Problems solved by technology

[0003] The sounder of the related art includes a front cover, a voice coil, and a magnetic frame for containing the voice coil. For the sounder of this structure, a hearing-aid voice coil is added under the front cover of the sounder or at the bottom of the magnetic frame. The problem lies in: Adding a hearing aid voice coil when the height of the sounder is limited will take up a lot of vibration space, and the induction magnetic field of the hearing aid voice coil will not be too strong, and the anti-interference ability is weak

Abstract

The invention provides an acoustic generator which comprises a magnetic frame and a hearing aid voice coil, wherein the magnetic frame is provided with a side wall and a lower bottom surface connected with the side wall; and the hearing aid voice coil is sleeved on the side wall. The acoustic generator can greatly improve the induced magnetic field of the hearing aid voice coil so as to improve the integral hearing aid function of the acoustic generator.

Description

【Technical field】 [0001] The invention relates to the field of sound generator design, in particular to a sound generator with strong anti-interference ability. 【Background technique】 [0002] With the development of electronic technology, electronic communication equipment is gradually developing in the direction of lightness, lightness and high sound quality. Therefore, how to realize the light and thin design of electronic communication equipment with high sound quality performance under the premise of ensuring product reliability has become a problem that the industry pays more attention to. [0003] The sounder of the related art includes a front cover, a voice coil, and a magnetic frame for containing the voice coil. For the sounder of this structure, a hearing-aid voice coil is added under the front cover of the sounder or at the bottom of the magnetic frame. The problem lies in: Adding a hearing-aid voice coil when the height of the sound generator is limited will t...
