Field of the Invention The present invention relates to a wrist-worn communication device having a cushion. [0002] 2. Description of the Related Art In a conventional communication device, electronic components such as a microphone and a speaker are provided in a housing thereof. A microphone or a speaker is provided with an air chamber space between the microphone and the housing or the speaker and the housing in order to expand the sound. A hole as a sound collection port or a sound emission port is opened in a part of the housing to secure a sound transmission path to the outside of the housing. In addition, most conventional communication devices that are not worn on the arm have no waterproof function except when used for special applications. [0003] In recent years, the miniaturization of communication devices has progressed remarkably, and communication devices worn on arms have also come into practical use. In the communication device worn on the arm, unlike the communication device not worn, it is necessary to have a waterproof structure to prevent the infiltration of moisture such as sweat. Therefore, in general, waterproof sheets have been used from the viewpoint of waterproofness and air permeability. 10-05-2019 1 Structurally, a waterproof sheet was attached to the inside of the sound release opening and the sound collection opening to prevent water from entering. Also, in the case of an arm-type communication device, it has been devised to place each in two band portions attached to the body in order to place the speaker in the ear and the microphone in the vicinity of the mouth. [0004] SUMMARY OF THE INVENTION However, in the case of arm-worn communication devices, it is easy for hand marks and dust to adhere around the sound outlet other than sweat, and when it is attempted to remove this, the waterproof sheet is damaged. There was a problem that it was easy to kill. If the tarpaulin is damaged, the waterproofness is naturally lost. Further, in the case of a curved band with a small radius of curvature, even if the speaker unit was to be put on the ear when making a call, the sound was not audible because the sound release port portion was not in close contact with the ear. [0005] Then, this invention is made in view of the above, Comprising: It aims at providing the arm-worn type communication apparatus which maintain and improve the waterproofness of a speaker, and a user's audibility. [0006] SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a band portion of a wrist-worn type communication device, wherein a sound port connecting the inside and the outside of a case is an acoustic device. An arm having a housing cover bored in a portion facing the housing, and a cushion attached to the housing cover for arranging the outer shape of the sound conduction port at a position planarly outside the outer shape of the sound port It is a wearable communication device. [0007] An acoustic device such as a microphone or a speaker is provided inside the case in the band portion of the wrist-worn communication device. These acoustic devices are embedded by the housing cover after being fitted in the recess of the 10-05-2019 2 housing. In the housing cover, a sound port for connecting the inside and the outside of the housing after mounting is formed as a sound emission port or a sound collection port. As a result, an air passage passing through the acoustic device and the outside of the housing is secured, and efficient sound transmission is possible. As a part where the above-mentioned sound port is pierced, the part which faces audio equipment is suitable. [0008] When the arm-worn communication device is used by removing it from the arm, a cushion is provided on the band portion facing the user's face. The cushion has a sound conducting port at a position different from a position where the sound port is extended substantially perpendicularly outward with respect to the housing. By this, it becomes possible to conduct the sound, and even if it is pierced with a thin rod material from the cushion outer surface in an attempt to take dust etc. of the sound conductive port, the rod material can touch the sound port of the housing cover. It disappears. The cushion maintains the above-mentioned positional relationship by engaging with the housing cover. The cushion also helps to conform to the shape of the ear against which it is applied and to prevent the sound from scattering. [0009] According to the present invention, the housing cover forms an air chamber so as to face the sound output portion of the speaker embedded in the housing, and a waterproof sheet is attached to the back surface. It is a device. [0010] In the arm-worn communication device, a speaker for the user to listen to sound is embedded in the housing. An air chamber formed by the housing cover is provided immediately before the sound emitting portion of the speaker. The air chamber is air-tight, and the oscillation of air necessary for sound transmission is secured. In addition, a waterproof sheet is attached to the back of the housing cover in order to prevent rain, sweat, and the like from entering the speaker. The site to be 10-05-2019 3 attached may be only the connection portion between the air chamber and the sound opening, or may be the inner wall of the air chamber including the connection portion. [0011] This invention is an arm-worn communication device in which the acoustic device is a microphone, and a waterproof sheet is attached to a portion of the case cover on the rear side of the opening of the case cover that faces the microphone. [0012] The arm attachment according to claim 1 or 3, wherein the cushion attached to the housing cover protrudes outside the string connecting the hinge of the curved band portion and the speaker tip, and has a sound conducting port at the protruding position. Communication equipment. [0013] A microphone is also embedded in the band portion of the wrist-worn communication device. A waterproof sheet is attached to the rear side of the cover of the case cover at a portion facing the microphone. As a result, sweat and water do not enter the microphone embedded in the housing. In the cushion engaged with the housing cover, a sound transmission port is formed at a position different from the position in which the sound port is extended substantially perpendicularly outward with respect to the housing. As a result, it becomes possible to conduct sound and temporarily prevent damage to the moisture permeable / waterproof sheet and the microphone even if they are pierced with a thin rod material from the cushion outer surface in order to take dust etc. of the sound conduction port. Also, even if it is a curved band fitted to the arm, the sound of the speaker can be received without leaking to the outside [0014] DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail 10-05-2019 4 with reference to the drawings. The present invention is not limited by the embodiment. [0015] FIG. 1 is a side sectional view showing a cushion structure of a wrist-worn communication device according to an embodiment of the present invention. The wrist-worn communication device 1 comprises a main body 2 and a band 3. Here, for convenience, the band 3 on one side to which the speaker 4 is attached will be described, and the band to which the microphone is attached is the same as the band except the air chamber described later will not be described. [0016] The arm-worn communication device 1 performs communication by putting the band 3 part on the ear. A speaker 4 is provided in the housing 5 at a portion to be in contact with the ear. The speaker 4 is embedded in the recess of the housing 5 and then embedded by the housing cover 6. A sound port 7 for connecting the inside and the outside of the housing 5 after mounting is formed in the housing cover 6 as a sound output port. As a result, an air passage passing through the speaker 4 and the outside of the housing cover 6 is secured, and efficient sound transmission becomes possible. As a site where the above-mentioned sound port 7 is pierced, a portion which faces an acoustic device is preferred. [0017] Just in front of the sound emitting portion 8 of the speaker 4, an air chamber 9 formed by the housing cover 6 is provided. The air chamber 9 is air-tight, and the swing of air necessary for sound transmission is secured. In addition, a waterproof sheet 10 is attached to the back of the housing cover 6 in order to prevent rain, sweat and the like from entering the speaker 4. As a site ¦ part to which the prevention sheet ¦ seat 10 is stuck, it may be only the connection part of the air chamber 9 and the said sound opening 7, or even if it is an inner wall of the air chamber 9 containing the said connection part as shown to a figure. Good. As the waterproof sheet 10, it is preferable to use a moisture-permeable, waterproof sheet that allows moisture to pass while maintaining the waterproof function. [0018] 10-05-2019 5 A cushion 11 is provided on the band 3 facing the user's face. The cushion 11 has a sound conducting port 12 at a position different from the position where the sound port 7 is extended outward in a substantially vertical direction with respect to the housing 5. Here, the position of the case 5 extending substantially perpendicularly outward with respect to the housing 5 means that the center axis of the sound port 7 is substantially perpendicular to the housing 5 and the center axis is extended outward. Position at which the cushion 11 is hit. The term generally perpendicular refers to the case where the sound opening 7 and the sound conduction port 12 overlap even if the axis is slightly deviated from the mathematical vertical, a position extended substantially outward with respect to the housing. It is because it contains in ". Here, the case cover 6 is included in the case 5. As a material of the cushion 11, a soft material such as silicone rubber or urethane resin is preferable. [0019] The sound conduction port 12 makes it possible to conduct the sound from the speaker 4. In addition, since the sound port 7 and the sound transmission port 12 are not arranged in a straight line, even if a groove is formed in the path connecting the both ports 7 and 12 in the housing cover 6, the device for enlarging the sound path is realized. Good. If the cushion has such a configuration, even if the dust or the like of the sound conduction port 12 is removed from the outer surface of the cushion 11 with a thin rod material, the rod material in the sound port 7 of the housing cover 6 Will not touch. If the sound port 7 is not touched, the waterproof sheet 10 attached to the back of the sound port 7 is not touched. [0020] The cushion 11 maintains the above-mentioned positional relationship by engaging 13 with the housing cover 6. As for the manner of engagement, as shown in the figure, it may be hooked to the hook portion of the housing cover 6 or may be fitted into a hole or a projection provided on the housing cover 6. Furthermore, a part may be hooked on the engaging part provided in a part of the housing cover 6 and the other part may be covered so as to wrap the housing cover 6 and the housing 5. In this way, if the cushion can be removed by engagement, if the cushion becomes dirty, it is convenient to be able to easily remove wrinkles, dust and the like due to sweat by removing only the cushion and washing with water. 10-05-2019 6 [0021] FIG. 2 is a side sectional view showing a structure for projecting a cushion attached to a housing cover in the vicinity of a string connecting a hinge of a curved band portion and a speaker tip and having a sound conducting port at the protruding position. The cushion 31 in this case has a dome shape in the vicinity of the string connecting the hinge of the housing and the tip end of the speaker, and has a dome shape, and the waterproof structure of the housing cover 26 and the speaker 24 inside Etc. are the same as in FIG. However, by arranging the sound conduction port 32 of the cushion 31 in the vicinity of a string connecting the hinge portion of the housing and the tip end of the speaker portion, the distance from the ear to the sound conduction port 32 is shortened and the gap is eliminated. As a result, the sound emitted from the sound conduction port 32 does not leak to the outside and can be heard well. In addition, I was able to improve the secrecy by eliminating the sound leakage to the outside. [0022] As described above, according to the cushion of the arm-worn type communication device according to the present invention, the sound port 7 of the band case cover 6 and the sound conduction port 12 of the cushion do not overlap. When removing dirt, dust and the like attached to the microphone, the microphone 4, the speaker 4 and the tarpaulin 10 are not accidentally damaged. In addition, in the case of a curved band 3 formed of plastic or the like, it is difficult to conform to the contour of the face even when placed on the ear during a call, so the sound opening does not contact the ear and is hard to hear. It was difficult to secure the secrecy. According to the present invention, by disposing the cushion 11 on the arm-worn type communication device, the adhesion with the ear can be increased, and the sound can be prevented from being scattered, which makes it easy to hear. Furthermore, the cushion is appropriately crushed even when wearing the arm-worn type communication device on the arm to fill a gap formed between the arm and the arm, thereby improving the holding power and thus improving the portability of the communication device. be able to. [0023] As described above, according to the arm-worn type communication device according to the present invention, since the sound port of the band case cover and the sound transmission port of the cushion do not overlap, around the sound transmission port There is no risk of accidentally damaging the built-in audio equipment when removing adhering dirt, dust and the like. 10-05-2019 7 [0024] Further, according to the present invention, since the air chamber is formed to face the sound emitting portion of the speaker embedded in the housing and the waterproof sheet is attached to the back surface, the sound from the speaker Spreads easily, and waterproofness is also maintained. In addition, since the sound port on the band case cover and the sound transmission port of the cushion do not overlap, when removing dirt, dust, etc. attached around the sound transmission port, the moisture transmission / water proof sheet and the built-in acoustic device I will not hurt you. [0025] Further, according to the arm-mounted communication device according to the present invention, the waterproof sheet is attached to the rear side of the sound port of the housing cover and facing the microphone, so that the microphone embedded in the housing can be used. Sweat, water will not penetrate. In the cushion engaged with the housing cover, a sound transmission port is formed at a position different from the position in which the sound port is extended substantially perpendicularly outward with respect to the housing. As a result, the sound can be transmitted, and even if dust or the like from the sound conduction port is removed from the outer surface of the cushion with a thin rod, the waterproof sheet and the microphone will not be damaged. [0026] Further, according to the arm-mounted communication device according to the present invention, in the curved band formed by plastic etc., it is difficult to conform to the contour of the face even when placed on the ear at the time of a call, so the sound opening does not contact the ear. By arranging a cushion for things that are difficult to hear, adhesion with the ear can be increased, it can be heard more easily, and confidential speech performance can be enhanced. 10-05-2019 8
