Problems solved by technology

When the vibration transmission plate is assembled on the bone conduction speaker, the structure of the connection part is prone to deflection, causing it to generate uneven vibration, or when the deflection is large, the voice coil etc. will touch the magnetic plate, and finally an abnormal sound will be formed. , the sound quality degrades

Embodiment Construction

[0021] Various preferred embodiments of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0022] A preferred embodiment of the vibration transmission plate device of the bone conduction speaker of the present invention, such as image 3 As shown, the vibration transmission plate 8 is a flat plate structure, and the flat plate body 801 is provided with a plurality of intermittent ring holes 802, and a rib portion 803 is arranged between each ring hole, so that the ring holes form a discontinuous interval; and the connecting ribs of adjacent ring holes are staggered, so that a vibration-transmitting sheet that is both rigid and elastic can be formed, and a balanced axial reciprocating movement can be achieved without special machining accuracy. Inclined, so as to meet the sound quality effect of the vibration plate. The vibration transmitting piece can be made of stainless steel or beryllium copper, and of course othe...

Abstract

The invention discloses a vibration conduction sheet device for a bone conduction loudspeaker. The vibration conduction sheet device comprises a plain film body, wherein the plain film body is provided with multiple circles of intermittent annular holes; rib connecting parts are arranged among each circle of annular holes, so that the annular holes are spaced intermittently; and the rib connecting parts of adjacent circles of annular holes are arranged in a staggered way. The vibration conduction sheet device of the bone conduction loudspeaker is provided with multiple circles of annular holes, so that a vibrating plate can be displaced more greatly, high sensitivity is realized for the bone conduction loudspeaker, and the output power of vibration and sound is increased. Moreover, balanced axial reciprocating movement of the vibration conduction sheet can be realized in a non-deviated way without special processing accuracy, so that a good tone quality is achieved.

Description

Technical field [0001] The invention involves a vibration device of a bone -conducting speaker. Background technique [0002] The reason why people can hear the sound is because the vibration in the air conveys the vibration to the eardrum through the outer ear canal and drives the human auditory nerves through the vibration formed by the eardrum. [0003] When the bone -leaving speaker works, it is passed through human skin, subcutaneous tissue and bones to human hearing nerves, so that people can hear the sound.In normal circumstances, as long as it is not damaged by Chinese and foreign ear or plugged in the ear canal by hand, the sound is directly transmitted through the bones and the output power transmitted to the sound to the eardrum.application. [0004] like figure 1 It is a three -dimensional diagram of the existing technical bone -leaving speaker structure.In this structure, it consists of two parts: driving parts and vibration parts.Driven components include pot -like ...
