Chamfers 2A1 and 2B1 are formed at portions where the slits 2A and 2B are connected to the outer shape.

At the approximate center of the cord holder 100, as will be described later, a first cord holding hole 3 is formed, which is a through hole having a diameter that allows the cord of the headphone to be locked and held by strong fitting. The first cord holding hole 3 and one through hole 1 </ b> A are connected by a slit 4.
The cord holder 100 is made of a known elastomer resin. Accordingly, the cord holder 100 can be elastically deformed, and the slits 2A, 2B, and 4 are passed through the cords 110CL, 110CR, and 110E of the headphones, and the earphone main body is strongly fitted into the through holes 1A and 1B. Can be held elastically.

Next, an embodiment of the headphone 110 provided with the cord holder 100 described above will be described with reference to FIG.
The headphone 110 includes a plug 110A connected to the headphone terminal 101A of the portable audio device 101, a left earphone 110BL, a right earphone 110BR, each of these earphones 110BL and 110BR, and a plug 110A. The cords 110CL and 110CR to be connected are provided. Electrical signals are supplied to the earphones 110BL and 110BR by the cords 110CL and 110CR.
The cords 110CL and 110CR are connected by a connector 110D, and the connector 110D and the plug 110A are integrated into a single cord 110E. The lengths of the code 110CL and the code 110CR may be different.

  In the cord holder 100 described above, for example, the cord 110E passes through the slit 4 and is held in the first cord holding hole 3. As a result, the cord holder 100 is locked to the cord 110E. The cord holder 100 is detachably attached to the cord 110E, and is configured to be used by being attached to the cord 110E for the purpose of preventing loss and convenience of handling.

The effect of the first embodiment will be described with reference to FIG.
FIG. 3A shows a state where the earphones 110BL and 110BR are held in the through holes 1A and 1B of the cord holder 100 when the headphones of the first embodiment are housed.

When the earphones 110BL and 110BR are attached to the through holes 1A and 1B, first, the cords 110CL and 110CR are passed through the slits 2A1 and 2B1, and then passed through the slits 110, and then the earphones 110BL and 110BR are passed through the through holes 1A. , 1B.
In this storage form, since the earphones 110BL and 110BR are integrated, it is possible to prevent the cords 110BL and 110BR from being entangled.

FIG. 3B shows an example of a state in which the cord length is optimized by eliminating the slack of the cord in the usage state of the headphones.
As described above, the cord 110E is held in the first cord holding hole 3.
Here, a length corresponding to the slack of the cord 110E (substantially equivalent to L in the figure) is turned back, passed through the slit 2B1, and wound several times between the through hole 1B and the outer shape. Since the surface of the elastomer resin has a high frictional resistance, the wound cord is held by the cord holder 100 by being wound several times.
Thereby, the slack of the code can be eliminated and the code length can be optimized. Of course, the winding may be performed on the through hole 1A, or may be wound so as to straddle both the through holes 1A and 1B.

As a second embodiment of the cord holder, a cord in which a second cord holding hole 5 independent of the first cord holding hole 3 is formed and the second cord holding hole 5 and the outer shape are connected via a slit 6 It is good also as the holder 100B. This is shown in FIG.
The cord holder 100B is formed with a first cord holding hole 3 that is a through hole having a diameter that allows the cord of the headphones to be held by strong fitting, and the first cord holding hole 3 and one through hole 1A. Are connected by a slit 4.
Furthermore, the second cord holding hole 5 independent of the first cord holding hole 3 described above is connected to the outer shape of the cord holder 100 </ b> B by the slit 6.

  The cord holder 100B is made of a known elastomer resin. Accordingly, the cord holder 100B can be elastically deformed, and the slits 2A, 2B, 4 and 6 can be passed through the headphone cords 110CL, 110CR and 110E, or the earphone main body can be passed through the through holes 1A and 1B. It can be held elastically with a strong fit.

  FIG. 2 shows an embodiment of the headphones 120 provided with the cord holder 100B described above. For example, the cord 110E passes through the slit 4 and is held in the first cord holding hole 3. As a result, the cord holder 100B is locked to the cord 110E. The cord holder 100B is detachable from the cord 110E, and is formed so as to be used by being attached to the cord 110E for the purpose of preventing loss and convenience of handling.

Next, the operation of the headphones 120 including the cord holder 100B described above will be described with reference to FIG.
FIG. 5A shows an example of a state in which the cord length is optimized by eliminating the slack of the cord when the headphones 120 are in use.
As described above, the cord 110E is held in the first cord holding hole 3.
Here, a length corresponding to the slack of the cord 110E (substantially equivalent to L in the figure) is folded back and allowed to pass through the slit 6 so as to be held by the second cord holding hole 5. Thereby, the slack of the code can be eliminated and the code length can be optimized.

Further, in the second embodiment, the cord length can be shortened and compactly stored while preventing the cord from being entangled.
FIG. 5B shows that when the headphones 120 of the second embodiment are housed, the earphones 110BL and 110BR are held in the through holes 1A and 1B of the cord holder 100B, respectively, and the cord 110E is folded back to make the second A state where the cord is held in the cord holding hole 5 is shown.

When the earphones 110BL and 110BR are attached to the through holes 1A and 1B, first, the cords 110CL and 110CR are passed through the slits 2A1 and 2B1, and then passed through the slits 110, and then the earphones 110BL and 110BR are passed through the through holes 1A. , 1B.
In this storage form, since the earphones 110BL and 110BR are integrated, it is possible to prevent the cords 110BL and 110BR from being entangled.

Further, the cord 110E is folded back by an arbitrary length L, passed through the slit 6, and held in the second cord holding hole 5.
By storing in such a form, the cord can be prevented from being entangled, and can be stored in a compact size by shortening the cord length.

  The first and second cord holding holes 3 and 5 are not limited to being formed at the positions described above. As shown in FIG. 4B, the cord holder 100C may be formed as cord holding holes 3C and 5 formed from the outer shape through slits 4C and 6 independently of the through holes 1A and 1B.

  Further, the slits 4 and 6 may be formed without forming the cord holding holes 3 and 5, but when the cord is sandwiched between the slits 4 and 6, the slit width is narrower than the cord diameter, so the slit 4 , 6 increases and the load on the cord holder increases, so it is desirable to form the cord holding holes 4 and 6 and hold the cords in the holes.

The width of each of the slits 2A, 2B, 4, 6 described above may be smaller than the outer diameter of the cord. Therefore, this width can be set wide enough to be substantially the same as the outer diameter of the through holes (2A, 2B) and the first and second cord holding holes (3, 5). In order to make it easy and difficult to come off, it is preferable that the width is approximately half the outer diameter of the cord.
Moreover, although it is good also as a slit which provides only a cut and is not normally open,
Since the force when passing the cord increases and it may be difficult to insert the cord, it is preferable to open the cord with the above-mentioned width.

In the embodiment of the present invention, since the cord holder is detachable from the headphones, for example, cord holders of various colors are formed, and the cord holder of the color matching the color of the clothes being worn. Fashion coordination is possible by selecting and attaching this to the headphones.
Further, even if the cord holder is unexpectedly broken, it is possible to replace only the cord holder without repairing or exchanging the entire headphone, so that the maintenance cost is extremely reduced.

  The embodiment of the present invention described above in detail is not limited to the above-described configuration, and may be modified as long as it does not depart from the gist of the present invention.
