Description

[Detailed Description of the Invention] The present invention relates to an ear hook type earphone device that can be hung on the left and right ears.

In conventional earhook type earphones, the earhook part is directly fixed to the outer periphery of the earphone body, or a support arm is set up on the outer periphery of the earphone body, and one end of the earhook part is fixed to this support arm. .

For this reason, the earphones were designed to be used only for the right or left ear, and were extremely difficult to wear when worn in the opposite direction.

Also, if you hang the earphone upside down, the earphone body will be upside down and the lead wire outlet will be on top, so if the lead wire is pulled, the earphone will easily come off and the stability when wearing it will be extremely poor. Met.

This invention was developed in consideration of the above circumstances, and it can be hung on either the right or left ear, has good wearability, and the lead wire outlet is always downward when worn on either the left or right side, ensuring stability when worn. The purpose is to provide a good earphone device.

Embodiments of the present invention will be specifically described below with reference to the drawings.

In Figure 1, 1 is the earphone main body, 2 is the lead wire lead-out part,
3 is an earmuff part.

A support arm 4 is erected on the outer periphery of the earphone main body in a direction opposite to the lead wire lead-out portion 2.

This support arm 4 is made of elastic, soft alloy or resin, and has a cylindrical attachment part 5 at its tip, and a fitting which is a through hole passing through this attachment part 5 is located in the center of this attachment part 5. A matching hole 6 is provided.

The fitting hole 6 is divided into two by a line connecting the lead wire lead-out portion 2 of the earphone main body 1 and the support arm 4, and opens toward the front and rear, respectively, and the axis of the fitting hole 6 and The cross-sectional shape in the orthogonal direction is a polygonal shape symmetrical with respect to the axis, that is, a so-called serration shape in which triangular teeth are carved on the inner peripheral wall.

Further, a split 7 is provided along the side surface of the mounting portion 5.

On the other hand, reference numeral 8 denotes an ear hook part, and one end thereof is provided with a fitting convex part 9 that removably fits into the above-mentioned fitting hole 6, and this fitting convex part has serrations similar to the above-mentioned fitting hole 6. It has a shape and is fitted by the elasticity of the mounting portion 5.

According to such a configuration, the ear hook part 8 is attached to the mounting part 5 provided at the tip of the support arm 4 before being divided into two by a line connecting the lead wire lead-out part 2 of the earphone main body part 1 and the support arm 4. ,
Since it can be attached and detached from the rear side, that is, from the directions A and B in the figure, it can be hung on either the left or right ear and has good wearability.

Furthermore, since there is no need to turn the earphone main body 1 upside down, the lead wire lead-out portion 2 is always at the bottom, providing good stability when worn, and the lead wire will not easily come off even if it is pulled.

Furthermore, even if a label with a brand name or the like is affixed to the back of the earphone body 1, the letters will not be upside down. Since the angle α between the ear hook 8 and the center line of the earphone body 1 can be arbitrarily set, the angle of the ear hook 8 can be freely adjusted to suit one ear of each individual. It is something.

In addition, the split 7 provided along the end surface of the attachment part 5 in this embodiment connects the fitting convex part 9 of the ear hook part 8 to the fitting hole 6 of the attachment part 5.
It is not necessarily necessary as long as it can be press-fitted or snap-fitted into the body.

Moreover, although the fitting hole 6 is made to pass through the attachment part 5, fitting holes may be provided at both ends of the attachment part 5, and it is not necessarily necessary to make the fitting hole pass through the attachment part 5.

As explained above, according to the present invention, when the earphone body is hung on either the left or right ear, the lead wire lead-out portion always stays at the bottom when worn on either the left or right side, improving stability when worn. By arbitrarily setting the angle between the ear hook part and the earphone body, the degree of negativity can be adapted to each individual using the earphone, which has a great practical effect.
