A sound plug 100 according to the present invention has a switching mode for switching between a mode in which the sound plug 100 is recognized as being inserted in the jack 700 and a mode in which the sound plug 100 is recognized as not being inserted in the jack 700. It is included. In this case, since it is not necessary to remove the plug, it is possible to prevent the plug from being removed and lost. [Selected figure] Figure 1 Acoustic plug [0001] The present invention relates to an acoustic plug connected to a device. [0002] An acoustic plug is standard equipment for the equipment. For example, there is an earphone terminal as an example of the acoustic plug. In recent years, development of devices using the earphone terminal has been advanced. [0003] For example, in Patent Document 1 (Japanese Patent Laid-Open No. 2010-136388), jack 10-05-2019 1 terminals for voice input and output of a portable terminal are diverted to connection terminals for digital cameras, input terminals for data communication cables such as USB cables, etc. Discloses a digital camera for portable information terminals and a portable information terminal connected digital camera device which do not need to have a dedicated terminal. [0004] The digital camera for portable information terminals of Patent Document 1 is a digital camera for portable information terminals connected to a portable information terminal provided with a jack terminal, wherein the digital camera body having a plug attachable to and detachable from the jack terminal, an audio circuit and an image circuit And when the plug is inserted into the jack terminal and electrically connected, the digital camera body transmits an image signal via the plug and the jack terminal. It transmits to the said portable information terminal. [0005] Further, in Japanese Patent Application Laid-Open No. 2013-51626, in the ear canal insertion type earphone device having a noise canceling function, the conventional configuration in which the battery box is formed in the cord upper housing portion is reviewed, An earpiece device with excellent acoustic performance is disclosed. [0006] The earphone device described in Patent Document 2 is an ear canal insertion type earphone device having a noise canceling function, and includes an L channel side housing portion in which an L channel side driver unit for emitting an L channel sound is accommodated, and an R channel An R channel side housing unit in which an R channel side driver unit that emits a sound is accommodated, and at least a microphone and a battery for noise canceling are respectively accommodated in the both housing units. [0007] JP, 2010-136388, A JP, 2013-51626, A [0008] As described above, in the digital camera for a portable information terminal that does not need to have the dedicated terminal disclosed in Patent Document 1, the camera can be easily connected to the earphone jack. 10-05-2019 2 In addition, in the ear canal insertion type earphone device having a noise canceling function of Patent Document 2, it is described that the wearing feeling and the acoustic performance can be made excellent. [0009] However, jacks in various devices are miniaturized, and naturally the acoustic plug is also miniaturized. In particular, the acoustic plug has come to communicate wirelessly with an earphone or the like, and in the absence of an earphone cable, it is further miniaturized. Therefore, the possibility of loss increases when the acoustic plug is removed. [0010] An object of the present invention is to provide an acoustic plug that can switch between a plug insertion mode and a non plug insertion mode with the plug inserted. [0011] (1) The acoustic plug according to one aspect includes a switching mode for switching between a mode in which the plug is recognized as being inserted in the device and a mode in which the plug is recognized as not being inserted in the device in a state of being inserted into the device. It is [0012] In this case, the acoustic plug can switch between a mode in which the plug is recognized to be inserted and a mode in which the plug is recognized not to be inserted. As a result, when the plug is inserted into the device, it can be recognized that the plug is not 10-05-2019 3 inserted into the device. [0013] For example, when playing music conventionally, it was necessary to remove the plug when inserting the plug and making it function as a microphone and a speaker during a call, but since the plug is small, it is likely to be lost There was a problem that. However, since the acoustic plug according to the present invention can be recognized that the plug is not inserted when it is inserted into the plug insertion port (plug jack), the acoustic plug can be prevented from being lost. [0014] (2) In the acoustic plug according to one aspect, the switching mode may be at least one of a mechanical system and an electrical system. [0015] In this case, since the switching mode includes at least one of the mechanical system and the electrical system, the mechanical system can be mechanically switched reliably, and the electrical system can be switched easily. [0016] (3) An acoustic plug according to a third aspect of the present invention is the acoustic plug according to the second aspect, wherein in the mechanical system, the tip of the plug may be eccentrically formed from the axial center. [0017] In this case, since the tip of the plug is eccentrically formed from the axial center, the eccentrically formed portion is inserted in the mechanical insertion recognition portion provided on the back side of the insertion port of the device. The case where the insertion recognition portion is touched and the case where the insertion recognition portion is not touched can be easily switched. 10-05-2019 4 [0018] (4) The acoustic plug according to the fourth aspect of the present invention is the acoustic plug according to the second or third aspect of the present invention, wherein the mechanical system may be provided with an unevenness switching mechanism in the circumferential direction at the tip of the plug. [0019] In this case, since the unevenness switching mechanism is provided in the circumferential direction of the tip of the plug, the plug is switched to the convex state in a state where the plug is inserted in the mechanical insertion recognition portion provided on the back side of the insertion port of the device. As a result, it is possible to easily switch between the case where the insertion recognition portion is touched and the case where the insertion recognition portion is not touched by switching to the concave state. [0020] (5) In the acoustic plug according to the fifth aspect of the present invention, in the acoustic plug according to the second to fourth aspects, the mechanical system may be provided with an unevenness changing mechanism in the axial direction at the tip of the plug. [0021] In this case, since the concavo-convex change mechanism is provided in the axial direction at the tip of the plug, the plug changes into a convex state in a state where the plug is inserted in the mechanical insertion recognition portion provided on the back side of the insertion port of the device. It is possible to easily switch between the case where the insertion recognition portion is brought into contact and the case where the insertion recognition portion is not brought in contact by changing the concave state. [0022] (6) The acoustic plug according to the sixth aspect of the present invention is the acoustic plug according to the second aspect of the present invention, wherein the mechanical system has the GND portion and the microphone signal portion alternately arranged in the axial direction of the plug May be [0023] In this case, since the GND portion and the microphone signal portion are alternately arranged in the axial direction of the plug, both types of CTIA and OMTP can be accommodated. 10-05-2019 5 [0024] (7) The acoustic plug according to the seventh invention is the acoustic plug according to the second invention to the sixth invention, wherein the mechanical system comprises a left audio signal unit, a right audio signal unit, a GND unit, a microphone signal unit, an insulation A left audio signal unit, a right audio signal unit, a GND unit, a microphone signal unit, and an insulating unit may be formed of a stretchable member, and may be deformed by the operation of the operating unit.

It may be done. [0027] In this case, since any one of the left audio signal unit, the right audio signal unit, the GND unit, the microphone signal unit, and the insulating unit has a mechanism for shifting the axial center, the axial center is shifted by the rotation operation of the operation unit. And friction with the inner wall of the jack can be increased. 10-05-2019 6 As a result, when an accessory or the like is attached to the operation unit, it is possible to realize removal prevention. [0028] (9) In the acoustic plug according to the ninth aspect of the present invention, in the acoustic plug according to the second aspect, the electrical system may have an insulating portion in a part of the tip of the plug. [0029] In this case, since the insulating portion is provided in part of the tip of the plug, the insulating portion is inserted in the electrical insertion recognition portion provided on the back side of the insertion port of the device. The case where the insertion recognition portion is brought into contact and the case where the conduction portion is not brought into contact with the insertion recognition portion can be easily switched. [0030] (10) The acoustic plug according to the other aspect switches the mode for switching between the mode for causing the device to recognize that the plug is inserted and the mode for causing the device to recognize that the plug is not inserted while being inserted into the device. The mechanical system in the switching mode has a left audio signal unit, a right audio signal unit, a GND unit, a microphone signal unit, an insulator and an operation unit, and the left audio signal unit, the right audio signal unit, the GND unit, the microphone Either one of the signal unit and the insulating unit may be formed of a stretchable member, and may be deformed by the operation of the operation unit. [0031] In this case, since any one of the left audio signal unit, the right audio signal unit, the GND unit, the microphone signal unit, and the insulating unit is formed of an elastic member, the elastic member is deformed by the operation unit. The friction with the inner wall of the jack can be increased. As a result, when an accessory or the like is attached to the operation unit, it is possible to realize removal prevention. 10-05-2019 7 [0032] (11) The acoustic plug according to the other aspect switches between a mode in which it is recognized that the plug is inserted in the device and a mode in which it is recognized that the plug is not inserted in the device in a state of being inserted in the device.

In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description about them will not be repeated. [0036] (One Embodiment) FIG. 1 is a schematic plan view showing an example of an acoustic plug 100 according to the present embodiment. 2 is a schematic perspective view showing a part of the acoustic plug 100, FIG. 3 is a schematic side view of the acoustic plug 100 of FIG. 2, and FIG. 4 is a schematic view of the acoustic plug 100 of FIG. It is a top view. [0037] As shown in FIG. 1, the acoustic plug 100 includes a left audio signal unit 110, a right audio signal unit 120, a GND unit 130, a microphone signal unit 140, a direction display unit 141, a knob unit 143, an accessory unit 142 and an insulating unit 150. Including. The direction display unit 141 displays the direction in which the sound plug 100 described later is inserted into the jack 700. In addition, the knob portion 143 rotates around the axis of the acoustic plug 100. Furthermore, the accessory unit 142 includes various devices or devices. [0038] Next, in FIGS. 2 to 4, the left audio signal unit 110, the right audio signal unit 120, the GND unit 130, the microphone signal unit 140 and the insulating unit 150 which are a part of the acoustic plug 100 are extracted and described. . [0039] 10-05-2019 10 As shown in FIGS. 2 to 4, the insulating unit 150 is between the left audio signal unit 110 and the right audio signal unit 120, between the right audio signal unit 120 and the GND unit 130, the GND unit 130 and the microphone signal unit. It is formed between 140. [0040] Further, as shown in FIGS. 2 to 4, the left audio signal unit 110 is eccentric to the axial center PJ of the right audio signal unit 120, the GND unit 130, the microphone signal unit 140, and the insulating unit 150. It is formed. That is, the protrusion 112 is formed between the curved surfaces 111 and 113 formed conventionally, and the surface 114 is opposite to the protrusion 112 so that the surface 114 is formed with respect to the axial center PJ. The curved surfaces 111 and 113 and the protrusion 112 are scraped on the side. [0041] Next, FIGS. 5 and 6 are schematic explanatory views showing a cross-sectional state in which the acoustic plug 100 shown in FIGS. 1 to 4 is inserted into the jack 700. FIG. [0042] As shown in FIGS. 5 and 6, the jack 700 is formed with terminal lines 710, 711, 720, 730, 740. In addition, a contact point 712 is formed between the terminal line 710 and the terminal line 711. [0043] As shown in FIG. 5, when the acoustic plug 100 is inserted into the jack 700 and the knob portion 143 is disposed vertically upward, the terminal line 710 is pushed vertically downward by the left audio signal unit 110, and the terminal The contacts 712 with the line 711 are separated. 10-05-2019 11 In this case, the terminal line 710 is in contact with the left audio signal unit 110. Also, the terminal line 720 is in contact with the right audio signal unit 120, the terminal line 730 is in contact with the GND unit 130, and the terminal line 740 is in contact with the microphone signal unit 140. [0044] Further, as shown in FIG. 6, when the acoustic plug 100 is inserted into the jack 700 and the knob portion 143 is disposed so as to be rotated vertically downward, the left audio signal portion 110 is eccentric, so the terminal line 710 is separated from the left audio signal unit 110, and the contact 712 of the terminal line 710 and the terminal line 711 is brought into contact. Also, the terminal line 720 is in contact with the right audio signal unit 120, the terminal line 730 is in contact with the GND unit 130, and the terminal line 740 is in contact with the microphone signal unit 140. [0045] In this case, even when the acoustic plug 100 is inserted into the jack 700, as shown in FIG. 6, since the left audio signal unit 110 is not physically in contact with the terminal line 710, the terminal line 710 and the terminal line The contacts 712 of 711 are in contact, and the terminal lines 710 and 712 are shorted. As a result, since the terminal line 710 and the contact point 712 are shorted although the acoustic plug 100 is inserted, the jack 700 can determine that the acoustic plug 100 is not inserted. [0046] Another Example Next, another example of the acoustic plug 100 shown in FIGS. 1 to 6 will be described. In the following, as described in FIGS. 2 to 4, a part of the acoustic plug 100 will be described.

[0048] Hereinafter, as shown in FIG. 7, in the acoustic plug 100 a, differences from the acoustic plug 100 of FIGS. 2 to 4 will be described. [0049] In the sound plug 100 a of FIG. 7, a left audio signal unit 110 a is formed instead of the left audio signal unit 110. The left audio signal unit 110a is formed with a concavo-convex mechanism 113a having a concavo-convex portion in comparison with the conventional left audio signal section 110a. The concavo-convex mechanism 113a moves in the direction of the arrow P2 by moving the operation unit 145 in the direction of the arrow P1. Conversely, the concavo-convex mechanism 113a moves in the direction opposite to the arrow P2 by moving the operation unit 145 in the direction opposite to the arrow P1. [0050] As shown in FIG. 8, when the concavo-convex mechanism 113a moves in the direction of the arrow P2, as shown in FIG. 5, the left audio signal unit 110a contacts the terminal line 710, and the contact 712 separates. Further, as shown in FIG. 9, when the concavo-convex mechanism 113a moves in the opposite direction to the arrow P2, as shown in FIG. 6, the left audio signal unit 110a separates from the terminal line 710 and the contact 712 contacts Do. [0051] The operation unit 145 may be connected to the knob unit 143 and the accessory unit 142, may be provided separately, and may be rotated as well as axially extended and contracted. 10-05-2019 13 [0052] Still Another Example Next, FIGS. 10 and 11 are schematic views showing another example of the acoustic plug 100. FIG. 10 and 11 are schematic perspective views showing an example of the acoustic plug 100b. [0053] Hereinafter, as shown in FIGS. 10 and 11, in the acoustic plug 100b, points different from the acoustic plugs 100 and 100a of FIGS. 2 to 4 will be described. The acoustic plug 100b has a left audio signal unit 110b made of a spherical shape. In the sound plug 100b, the left audio signal unit 110b is moved in the direction of the arrow P3 by moving the operation unit 145 in the direction of the arrow P1. Conversely, the left audio signal unit 110b moves in the direction opposite to the arrow P3 by moving the operation unit 145 in the direction opposite to the arrow P1. [0054] Further, as shown in FIG. 10, when the left audio signal unit 110b moves in the direction of the arrow P3, as shown in FIG. 6, the left audio signal unit 110b separates from the terminal line 710 and the contact 712 contacts. When the left audio signal unit 110b moves in the direction opposite to the arrow P3, as shown in FIG. 5, the left audio signal unit 110b contacts the terminal line 710, and the contact 712 is separated. [0055] Still Another Example Next, FIGS. 12, 13 and 14 are schematic views showing another example of the acoustic plug 100. FIG. FIG. 12 is a schematic perspective view showing an example of the acoustic plug 100c, and FIG. 13 is a schematic side view of the acoustic plug 100c. 10-05-2019 14 [0056] As shown in FIG. 12 and FIG. 13, the difference between the acoustic plug 100 c and the acoustic plugs 100, 100 a and 100 b will be described. The acoustic plug 100c has a left audio signal unit 110c and a right audio signal unit 120, and further has a plurality of GND units 130c, a plurality of microphone signal units 140c, and insulating units 150 and 150c. [0057] As shown in FIGS. 12 and 13, the plurality of GND units 130c and the plurality of microphone signal units 140c are alternately arranged at 90 degrees by being divided. In addition, the microphone signal unit 140c is disposed adjacent to the entire periphery of one GND unit 130c. Also, the GND portion 130c is disposed adjacent to the entire periphery of one microphone signal portion 140c. In addition, an insulating unit 150c is provided between the GND unit 130c and the microphone signal unit 140c. As a result, the GND portion 130c and the microphone signal portion 140c are alternately arranged. [0058] As a result, since the GND portion 130c and the microphone signal portion 140c are alternately arranged, it is possible to connect any type of cellular telephone industry association (CTIA) and open mobile terminal platform (OMTP). [0059] Subsequently, FIG. 14 is a schematic perspective view of the acoustic plug 100 d, FIG. 15 is a schematic explanatory view of an AA cross section of the acoustic plug 100 d, and FIG. 16 is a BB cross section of the acoustic plug 100 d.

As shown in FIGS. 15 and 16, microphone signal units 140d and GND units 130d are alternately arranged in the axial direction. An insulating unit 150d is disposed between the GND unit 130d and the microphone signal unit 140d. [0063] As a result, since the GND portion 130 d and the microphone signal portion 140 d are alternately arranged, it is possible to connect any type of Cellular Telephone Industry Association (CTIA) and Open Mobile Terminal Platform (OMTP), Furthermore, when the GND portion 130 d and the microphone signal portion 140 d are unnecessary, the plurality of resin portions 160 d come into contact with the terminal lines 730 and 740 and there is no electrical continuity, so that the microphone output can be cut. [0064] In the acoustic plugs 100c and 100d shown in FIGS. 12 to 16, the decentered left audio signal unit 110 shown in FIGS. 1 to 4 may be provided instead of the left audio signal units 110c and 110d.

Further, the sound plug 100 f is provided with a character cover fixing projection 177. As a result, the character cover made of an elastic body can be inserted into the character cover fixing projection 177 and fixed. In addition, in the acoustic plug 100f, the insertion protection portion 170 or the character cover fixing projection 177 may be formed in a polygonal shape, an elliptical shape, or a circular shape. In that case, when the character cover is attached, the direction of the acoustic plug 100f can be easily confirmed. [0067] Still Another Example FIGS. 20 to 22 show still another example of the acoustic plug 100. FIG. FIG. 20 shows a schematic plan view of the acoustic plug 100g, FIG. 21 shows a schematic plan view of the acoustic plug 100g when the state changes, and FIG. 22 schematically shows the acoustic plug 100g when the state is further changed. A top view is shown. [0068] The acoustic plug 100g shown in FIGS. 20 to 22 includes a left audio signal unit 110g made of a 10-05-2019 17 conductive stretchable material. The left audio signal unit 110 g is deformed by the operation of the operation unit 145. [0069] Specifically, as shown in FIG. 20, when the acoustic plug 100g is inserted into the jack 700, the left audio signal unit 110g does not physically contact the terminal line 710, and the contact 712 is in contact with it. Become. Next, as shown in FIG. 21, when the operation unit 145 is moved in the direction of the arrow P1, the left audio signal unit 110g made of a conductive stretchable material deforms and contacts the terminal line 710, and the contact 712 separates. Do. [0070] As a result, the left audio signal unit 110 g conducts with the terminal line 710. Furthermore, as shown in FIG. 22, when the operation unit 145 is further moved in the direction of the arrow P1, the left audio signal unit 110g made of a conductive stretchable material is deformed and contacts the inner wall of the hole of the jack 700, The friction between the acoustic plug 100g and the jack 700 is increased, and it becomes difficult to pull out. [0071] Note that a latch mechanism or latch structure capable of maintaining or holding each state shown in FIG. 20, 21 or 22 may be separately provided. [0072] Still Another Example FIGS. 23 to 25 show still another example of the acoustic plug 100. FIG. FIG. 23 shows a schematic plan view of the acoustic plug 100h, FIG. 24 shows a schematic plan view of the acoustic plug 100h at the time of a state change, and FIG. 25 schematically shows the acoustic plug 100h when the state is further changed. A top view is shown. [0073] 10-05-2019 18 The acoustic plug 100 h shown in FIGS. 23 to 25 includes a right audio signal unit 120 h made of a conductive stretchable material. The right audio signal unit 120 h is deformed by the operation of the operation unit 145. [0074] Specifically, as shown in FIG. 23, before the sound plug 100h is inserted into the jack 700 and the operation unit 145 is pulled out in the direction of the arrow P1, the right audio signal unit 120h is not deformed. Next, as shown in FIG. 24, when the acoustic plug 100h is inserted into the jack 700 and the operation unit 145 is pulled out in the direction of the arrow P1, the right audio signal unit 120h is deformed from the axis toward the outer periphery. As a result, it contacts the inner wall of the hole of the jack 700, the friction between the acoustic plug 100h and the jack 700 increases, and the extraction becomes difficult. [0075] Furthermore, as shown in FIG. 25, when the operation unit 145 is further moved in the direction of the arrow P1, the right audio signal unit 120h made of a conductive stretchable material is deformed and contacts the inner wall of the hole of the jack 700, The friction between the acoustic plug 100 h and the jack 700 is increased, and the extraction becomes even more difficult. [0076] In the above description, the right audio signal unit 120h is made of a conductive stretchable material, but the invention is not limited thereto. The insulating unit 150 may be formed of a nonconductive stretchable material. The microphone signal unit 140 may be formed of a conductive stretchable material. [0077] In addition, a latch mechanism or latch structure capable of maintaining or holding each state shown in FIG. 23, 24 or 25 may be separately provided. [0078] 10-05-2019 19 (Still Another Example) FIGS. 26 and 27 show still another example of the acoustic plug 100. FIG. FIG. 26 shows a schematic plan view of the acoustic plug 100j, and FIG. 27 shows a schematic plan view of the acoustic plug 100j at the time of state change. [0079] As shown in FIGS. 26 and 27, the acoustic plug 100j includes a right audio signal unit 120j, a GND unit 130j, and a microphone signal unit 140j. The right audio signal unit 120j, the GND unit 130j, and the microphone signal unit 140j individually move the axial centers in different directions by rotating the operation unit 145 in the direction of the arrow R1. [0080] Specifically, as shown in FIGS. 26 and 27, the sound plug 100j rotates the operation unit 145 in the direction of the arrow R1, whereby the right audio signal unit 120j and the microphone signal unit 140j move vertically upward. As a result, the GND portion 130 j moves vertically downward. As a result, it contacts the inner wall of the hole of the jack 700, the friction between the acoustic plug 100j and the jack 700 increases, and the extraction becomes difficult. [0081] Further, in the above description, although the axial centers of the right audio signal unit 120j, the GND unit 130j, and the microphone signal unit 140j are moved, the present invention is not limited to this, the right audio signal unit 120j, the GND unit 130j, Alternatively, one or two axes of the microphone signal unit 140 j may be moved, and horizontal and vertical directions may be used instead of the vertically upward and downward directions. 10-05-2019 20 [0082] Although the operation unit 145 has been described, the present invention is not limited to this, and a cable or an accessory may be attached to the operation unit 145. In this case, it is possible to form a fall prevention structure when a cable, an accessory or the like is attached. Furthermore, although the operation unit 145 is rotated in the direction of the arrow R1, the present invention is not limited to this, and a push type operation unit of push-in may be used. [0083] Furthermore, in the above embodiment, although the microphone signal units 140 to 140j are used, the present invention is not limited to this, and a microphone signal unit for noise canceller may be further provided, and the microphone signal units 140 to 140j. May be divided into left and right microphone signal sections. [0084] Also, although the acoustic plugs 100, 100a to 100j have been described in the present embodiment, the present invention is not limited to this, and the present invention can be applied to plugs other than the plugs relating to acoustics. [0085] In addition, a latch mechanism or latch structure capable of maintaining or holding each state shown in FIG. 26 or 27 may be additionally provided. [0086] In the case where the terminal line 710 contacts or separates from the left audio signal unit 110 by the rotation of the left audio signal unit 110 as shown in FIG. 5 or 6, when the user rotates the knob 143, the left The audio signal unit 110 rotates. The change from the state in which the terminal line 710 contacts the left audio signal unit 110 10-05-2019 21 to the state in which the terminal line 710 is in the separated state has an effect that the user can easily determine by the change in the force required for rotation. Further, the end portion of the left audio signal unit 110 may be provided with unevenness so that a click feeling may be generated when changing from the state in contact with the left audio signal unit 110 to the separated state. [0087] As described above, the acoustic plugs 100, 100a to 100j according to the present invention can switch between a mode for recognizing that a plug is inserted and a mode for recognizing that a plug is not inserted. As a result, when the acoustic plug 100 is inserted into the device, it can be recognized that the acoustic plug 100 is not inserted into the device. Since the sound plug 100 can be recognized as not being inserted into the jack 700 when the sound plug 100 is inserted, loss of the sound plug 100 can be prevented. [0088] Further, since the acoustic plugs 100g and 100h have conductive stretchable members, the friction between the acoustic plugs 100g and 100h and the inner wall of the jack 700 can be enhanced. As a result, extraction prevention of the plugs 100g and 100h from the jack 700 can be realized. In addition, since the acoustic plug 100 j has a mechanism for shifting the axis, extraction prevention can be realized similarly. [0089] The sound plug according to the present invention corresponds to a mode in which the state of FIG. 5 recognizes that it is inserted, corresponds to a mode in which it recognizes that the state is not inserted, and the left audio signal unit 110 switches In the mode, the acoustic plugs 100, 100a to 100j correspond to the acoustic plugs, the left audio signal unit 110 corresponds to the eccentrically formed mechanical system, and the concavo-convex mechanism 113a corresponds to the concavo-convex switching mechanism in the circumferential direction. Correspondingly, the left audio signal unit 110b corresponds to the unevenness changing mechanism in the axial 10-05-2019 22 direction, the GND units 130 and 130c correspond to the GND units, and the microphone signal units 140, 140c, 140d and 140j correspond to the microphone signal units, and the left The audio signal units 110, 110a, 110b, 110c, 110d, and 110g correspond to left audio signal units, and the right audio signal units 120, 120j, and 120h correspond to right audio signal units. Correspondingly, the insulating portions 150, 150c and 150d correspond to the insulating portions, the operation portion 145 corresponds to the operation portion, the left audio signal portion 110g and the right audio signal portion 120h correspond to the elastic members, and the right audio signal portion Reference numerals 120 j and 130 j and the microphone signal unit 140 j correspond to a mechanism for shifting the axis.
