Description

A kind of structural bone conduction microphone of supporting type
Technical field
The utility model is used for communication apparatus or for detecting voice signal, is specifically related to a kind of structural bone conduction microphone of supporting type.
Background technology
General microphone utilizes air vibration to conduct, and belongs to completely open, but cannot shield background noise, under various noisy environment, cannot obtain the sound clearly oneself wanted.
Bone-conduction microphone is a kind of by directly fitting with sound source and conducting the device of sound, it only can conduct the signal of sound source of fitting with it, universal along with mobile phone and mobile device, various relatively noisy environment is more and more higher to communication need, require that mobile phone or equipment will have the ability of filter background noise, the vibration that bone-conduction microphone can be produced by the sound source of fitting with it is converted into the signal of telecommunication, thus masks the noise of environment.
The requirement of people to sound is now more next high, ites is desirable to obtain more clear and pure sound, and common bone-conduction microphone sensitivity is poor, and the unintelligible or noisy sound of background of the sound of transmission cannot be filtered dry only, so wish that the sound improved is more and more stronger.
Utility model content
The purpose of this utility model is for solving above-mentioned deficiency, provides a kind of structural bone conduction microphone of supporting type, thus obtains more clear and clean sound.
The purpose of this utility model is achieved through the following technical solutions:
A kind of structural bone conduction microphone of supporting type, comprise pickup parts, magnetic circuit part and signal of telecommunication conversion voice coil loudspeaker voice coil, pickup parts connect magnetic circuit part, magnetic circuit part connects signal of telecommunication conversion voice coil loudspeaker voice coil, described pickup parts comprise adhesive sheet, elasticity resonance plate and retainer ring, there is the reference column for connecting at adhesive sheet center, elasticity resonance plate is positioned over the reference column center on adhesive sheet and bonds with glue, retainer ring presses on elasticity resonance plate, described magnetic circuit part comprises magnetic core, T-shaped iron core and main body fixed mount, main body fixed mount center is porose, magnetic core is placed on the inside blend compounds water bonding along main body fixed mount center, T-shaped iron core is put in the bonding of main body fixed mount centre bore cap surface blend compounds water, T-shaped core center post direction inwardly.
The utility model also has some technical characteristics like this:
Described signal of telecommunication conversion voice coil loudspeaker voice coil is fixed on T-shaped iron core.
The elasticity resonance film perforation of described pickup part is connected with the main body fixed mount screw of magnetic circuit part.
Described elasticity resonance plate has highly sensitive a kind of version, replaceable another kind of version.
Described microphone passes through adhesive sheet and the magnetic circuit part adhesive of pickup part, impels magnetic field to change, and is exported by signal after producing the signal of telecommunication by the magnetic line of force of signal of telecommunication conversion voice coil loudspeaker voice coil cutting change.
The utility model has effect useful as follows:
The utility model is reasonable in design, easy to use, and the elasticity resonance plate structure of employing has very high sensitivity, can pick up trickleer vibration, be amplified by voice signal.
Accompanying drawing explanation
