Problems solved by technology

[0004] Also, in the case of the above-mentioned structure, a thinner cushioning material is used in order to suppress the thickness, but the cushioning effect of this cushioning material is weakened, and the isolation between the housing and the bone conduction speaker cannot be sufficiently ensured.
As a result, the return compensation becomes larger, so there is a problem that a large output cannot be avoided in order to avoid this situation.

Embodiment Construction

[0029] Preferred embodiments of the present invention will be described with reference to the drawings. In the following, a bone conduction speaker will be described as a bone conduction device, but this description is also applicable to a bone conduction microphone. That is, the reason is that the difference between the two devices is that the vibration is transmitted from the vibrating plate to the skull, or the vibration of the skull is picked up by the vibrating plate. Although the functions are different, the structure is substantially the same.

[0030] First, for Figure 1 and figure 2 The illustrated embodiment will be described. The embodiment shown here is characterized in that a bone conduction speaker 1 is used as a speaker, a recess 3 having a diameter larger than that of the bone conduction speaker 1 is provided on the casing 2 of the main body of the telephone, and the inner surface of the recess 3 is in contact with the A cushioning material 4 is provided bet...

Abstract

A portable telephone using a bone conduction speaker, enabling production of high output without an increase in the thickness of a housing of a telephone body and having no problem of the use in a noisy environment. In the portable telephone, a bone conduction speaker (1) is used as the speaker, a depression (3) having a diameter greater than that of the bone conduction speaker (1) is provided in a housing (2) of a telephone body, a cushioning material (4) is installed between the inner surface of the depression (3) and the outer surface of the bone conduction speaker (1), and the bone conduction speaker (1) is supported by the cushioning material (4) with a gap maintained between the speaker and the bottom of the depression (3) and with the vibration surface of the speaker being flush with or slightly projecting from the surface of the housing (2).

Description

technical field [0001] The present invention relates to a portable telephone using a bone conduction device, and more particularly, to a portable telephone using a bone conduction device as a speaker and / or a microphone, and the bone conduction device is Press against the head to listen to the voice of the receiver and pick up the bone conduction sound. Background technique [0002] Usually, for example, a method is adopted in which the bone conduction speaker 31 in a portable telephone using a bone conduction device is housed in the recessed portion 33 via a cushioning material 34 for ensuring isolation from the case 32, so that The recessed portion 33 is disposed at a proper position of the housing 32 along the thickness direction. The cushioning material 34 may only be disposed on the bottom surface of the recessed portion 33 ( Figure 10 ), can also be configured from bottom to side ( Figure 11 ). [0003] In the case of the above-mentioned portable telephone using t...
