Lh surface [ The holder is made of a plastic material or rubber as a whole, because of the thin wall of 5. 籠 On the upper surface of! 5, there is a peripheral wall that accepts contact attachments pressed against the human body. The bone conduction speaker unit according to claim 8 for solving the above-mentioned problem is such that the bone-inductive speaker force is supported by the holder and a self-contact is attached to the teii wall. Become. The invention's effect

 According to the bone conduction speaker holder and the bone conduction speaker unit according to the present invention, the entire surface to be removed of the bone conduction speaker is made elastic, and is formed at the center of the inner surface. During non-calling, only the protrusions are in contact with the bone conduction speaker in a point-like manner, making it difficult for the contact to be transmitted to the contacts, and suppressing the appearance of sound due to the contact sound being added. Therefore, the occurrence of sound leakage can be suppressed. And during a call, press the contact attachment against the head etc. ^ ¾ force ^, Bj¾

The effect that the i¾ of the plate can be securely and sufficiently fitted to the contact attachment and the function of the bone conduction speaker can be exerted positively by the frT of the inner surface of ¾B being formed in a planar shape on the i¾b plate having a bone-inductive speaker force. There is.

 In addition, since the top 15 of the bone conduction speaker contained in the holder according to the present invention is hermetically sealed in the holder, the waterproofness and the dust proof I ”are maintained over the bone conduction speaker. The best mode for carrying out the invention

 The best mode for spiriting the present invention will be described with reference to the drawings. FIG. 1 is a top view of a bone conduction speaker unit using the bone conduction speaker holder according to the present invention, and FIG. 2 is a view thereof.

 The bone conduction speaker holder 1 according to the present invention is made of an elastic material such as elastic plastic or rubber, and surrounds and supports the whole bone conduction speaker force 2 and is movable to cover the upper surface of ^ ¾ 3 It consists of four.竊 corresponds to the shape of the bone conduction speaker 2 that goes inside the machine, and in the illustrated example, it has a body shape with rounded corners.

Overhang 5 and 6 forces s are formed at 黯 and υπ¾ ^ on the inner peripheral surface of 雜, respectively. The movable top surface 4 is integrally formed by extending the upper overhanging portion 5 of 竊 3 inward, but its peripheral edge. By making the part a thin-walled part 7, + ^ is given. On the inner surface of gradual 4, typically: ^ ¾, one or more 158 forces S are formed. This tip is always in contact with the ig¾ plate of the bone conduction speaker 2 in a dotted manner.

 The opening 13 at the bottom of the bone conduction speaker hono-reder 1 is used as the heel entrance of the bone conduction speaker force 2 and also serves as the bow I outlet of the electrical tie of the bone conduction speaker force 2. The lower overhanging portion 6 serves as a retainer after the bone conduction speaker 2 is loaded. In addition, a fixing overhang 9 is formed below the outer surface | 5 of the forehead 3. The overhang 9 for fixing is used to fix the bone conduction speaker unit composed of the bone conduction speaker holder 1 to the receiving »^ band l tongue casing 2 1 etc. , Screw holes 10 etc. Force S is suitable.

 The peripheral edge of the upper surface of the flange 153 is extended to Ji *, and a peripheral wall 11 1 force S that is flush with the outer surface of the flange 3 is formed. Inside the peripheral wall 1 1 is a contact member 1 2 force S to be pressed against the human body (main ^ IM part), and the contact 、 1 2 is employed there. The outer surface of the contact bracket 12 that contacts the human body is slightly curved, and the inner surface is in close contact with the upper surface of the top surface 4 when it is inside the peripheral wall 11 1 (usually craned). As a result, the “SJ” on the top 4 will be connected to the Iffig and surely contact 1 2.

 The structure of the bone conduction speaker 2 is not particularly different from that used in the past. In other words, in the middle of the yoke 1 5, the voice coin 1 6 is self-assembled, the magnet 1 7 is fixed to both sides j, and the side plate 1 8 that is set up from both jobs of the yoke 15 is used to support the β support plate 1 9 Is supported on the voice coil 1 6 with a dynamic gap. A central opening force S is formed on the viewing support plate 19, and a plate yoke 20 is fixed on the plate 19 so as to face it, and ^ 8 comes into contact with the upper surface of the plate yoke 20. It should be noted that the magnet is placed on the inside of the voice coil, and the door is formed in the stomach.

 158 When 158 is loaded with bone conduction force 2, its tip slightly lightly worms onto plate yoke 20 with bone conduction force 2 and the! 58 itself is elastic, so it can be contacted during a call. When the bracket 1 2 is pressed against the head, the surface of the plate yoke 20 with the bone conduction speaker force 2 is brought into close contact with the “^ ¾ 8 force S. In this state, the sound signal S is generated by the audio signal. Then, the contact is connected to contact 12 through 4 and bone conduction conversation can be performed as before.

When not talking, the tip of 雜 | 58 is attached to the plate yoke 20 with bone conduction speaker force 2. Because it is only lightly square! ^, Even if the plate yoke is 20 0 force S, it is difficult for the fiber to contact the contact 1 2 and that unintentional sound leakage occurs. It is done. The bone conduction speaker unit according to the present invention is a high-quality material, and the bone conduction speaker 2 is sealed in the bone conduction speaker holder 1 on its side surface, so that it is easy to be waterproof and anti-comfort. Have a tatami mat.

 In order to demonstrate the effectiveness of the present invention, the ratio between the conventional type of bone conduction speaker holder shown in FIG. 4 and the sample of the present invention was compared. This test measured sound leakage as a sound when a sine wave input was applied to each bone conduction speaker force. As is apparent from the Dharaf of FIG. 3 showing the result, the difficult product of the present invention uses the conventional bone conduction speaker holder over the entire frequency band of 500 Hz to 6 kHz! Better results than those obtained were obtained, and the present invention was able to produce) †.

 Although the present invention has been described in detail in its most preferred form, it is possible to construct a wide variety of different forms without departing from the spirit and scope of this invention. It will be apparent that the invention is limited in scope to the scope of the appended claims, but is not limited to that particular embodiment.
