The height at end.
Preferably, the width near described side wall one end for the described cover plate is less than described cover plate near described loudspeaker monomer one
The width at end.
The beneficial effects of the utility model are：
First, the speaker module that this utility model provides passes through setting and separates being made from a material that be thermally conductive of ante-chamber and back cavity
Cover plate, heat conducting cover plate can be conducted the heat in back cavity to ante-chamber, and due to ante-chamber, to connect result of ventilating heat dissipation good with going out acoustic aperture
Thus improving the radiating effect of whole speaker module, improve reliability and the acoustical behavior of speaker module.
2nd, heat conducting cover plate is made up of the aluminium oxide ceramics of high heat conduction, aluminium nitride ceramics, carborundum and liquid metal, due to
These materials are phase-change material, do not interfere with the performance of the antenna near speaker module.
