[0002]

2. Description of the Related Art FIG. 7 is a configuration diagram of a conventional earphone, and FIG. 8 is a perspective view when the earphone of FIG. 7 is attached.

In these figures, an earphone 1 includes a plug 3 connected to a reproducing device, earphone bodies 5 and 7 worn on the ears, and cords 9 and 11 connecting the plug 3 and the earphone bodies 5 and 7. It is roughly divided into.

In the middle of the cords 9 and 11, there is provided a box 13 for controlling the volume for adjusting the reproduction volume and the reproduction equipment to which the earphone 1 is connected. The cord between the box 13 and the plug 3 is provided. 9 and 11 are integrated, and the cords 9 and 11 between the box 13 and the earphone bodies 5 and 7 are separated.

Furthermore, in order to prevent the earphone bodies 5 and 7 from coming off the ears due to the weight of the box 13, a hook (not shown) attached to clothes is attached to the box 13.
Is provided.

When the earphone 1 having such a structure is mounted, the cords 9 and 11 separated between the box 13 and the earphone bodies 5 and 7 may be disengaged from the ears.

The same applies when the box 13 is moved while the box 13 is being operated. In order to solve such a problem, earphones having the configurations shown in FIGS. 9 and 10 have been proposed.

In the figure, a strap holder 21 is provided on separate cords 9 and 11 between the box 13 and the earphone bodies 5 and 7. This strap holder 2
Reference numeral 1 includes a first strap holder 23 provided on the cord 9 and a second strap holder 25 provided on the cord 11 and detachable from the first strap holder 23.

Then, as shown in FIG. 10, when the earphone is worn, the first strap holder 23 and the second strap holder 23 are attached at the rear of the neck.
And the strap holder 25 of No. 1 are engaged with each other to form a necklace-shaped cord annular portion 27.

By forming the cord annular portion 27 as described above, even if the cords 9 and 11 are hooked, the earphone bodies 5 and 7 are unlikely to come off from the ears. Further, even if the box 13 is moved while the box 13 is being operated, the earphone bodies 5 and 7 are also unlikely to come off from the ears.

An example of the structure of the strap holder 21 will be described with reference to FIGS. 11 and 12. In these drawings, each of the first strap holder 23 and the second strap holder 25 has a substantially hollow hemispherical shape.

An outer step portion 23a is formed along the entire circumferential direction on the outer peripheral surface of the first strap holder 23 near the open surface, and an inner peripheral surface of the second strap holder 25 near the open surface is formed. An inner step 25a engageable with the outer step 23a of the first strap holder 23 is formed along the entire circumferential direction.

Further, the first strap holder 23 has
Tongue portion 23b protruding from the inside through the open surface to the outside
However, the second strap holder 25 is formed with a tongue portion 25b that projects outward from the inside through the open surface.

Then, the outer step portion 23a of the first strap holder 23 and the inner step portion 25a of the second strap holder 25 are engaged with each other, and the first strap holder 2
When the third strap holder 25 and the second strap holder 25 are integrated, the tongue portion 23b of the first strap holder 23 and the second strap holder 25
The tongue portions 23b and 25b are provided so that the tongue portion 25b of the strap holder 25 of FIG.

The tongue portion 25 of the second strap holder 25 of the tongue portion 23b of the first strap holder 23
A protrusion 23c is formed on the surface facing b. Similarly, the first portion of the tongue portion 25b of the second strap holder 25 is
On the surface of the strap holder 23 facing the tongue portion 23b, a protrusion 25c capable of contacting the protrusion 23c of the first strap holder 23 is formed.

The first strap holder 23 having the above structure
To integrate the second strap holder 25 with the second strap holder 25, as shown in FIG.
The first strap holder 23 and the second strap holder 25 are in a state where the tongue portion 23b of the third strap holder 3 and the tongue portion 25b of the second strap holder 25 can overlap each other.
, And the first strap holder 23 is moved in the direction of arrow I.

Then, the protrusion 23c of the tongue portion 23b of the first strap holder 23 is fixed to the second strap holder 2
After overcoming the protrusion 25c of the tongue portion 25b of No. 5, the integration of the first strap holder 23 and the second strap holder 25 is completed.

[0018]

However, the strap holder 21 having the above structure has the following problems.

(1) The first strap holder 23,
When integrating with the second strap holder 25,
When the tongue portion 23b of the first strap holder 23 and the tongue portion 25b of the second strap holder 25 can overlap with each other, the first strap holder 23 and the second strap holder 23
The strap holders 25 and must be positioned.

That is, circumferential positioning is required. In particular, this strap holder 21 comprises a first strap holder 23 and a second strap holder 2 behind the neck.
Since 5 and 5 are integrated, there is a problem that it is very difficult to handle.

(2) Since the first strap holder 23 and the second strap holder 25 are substantially hemispherical, there is also a problem that they are small and difficult to grip. The present invention has been made in view of the above problems, and a first object thereof is to provide a strap holder for an earphone that can be easily integrated.

A second object is to provide a strap holder for an earphone that is easy to grip.
