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]

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.

(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.

[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]
