Title:
SOUND PRODUCTION DEVICE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/035870
Kind Code:
A1
Abstract:
Disclosed is a sound production device, comprising: a vibration assembly, wherein the vibration assembly comprises a voice coil (4), and a support structure (5) connected to the voice coil (4) and supporting the voice coil (4); a diaphragm (1), wherein one end of the diaphragm (1) is fixedly connected to the support structure (5) by means of a first cone (2); and a cover body (3), wherein the cover body (3) is connected to one end, close to the diaphragm (1), of the support structure (5); and the sound production device further comprising a reinforcing part, wherein one end of the reinforcing part is fixedly connected to the first cone (2), and the other end thereof is combined with the cover body (3). The sound production device can effectively improve the FR high-frequency response. In addition, further disclosed is an electronic apparatus using the sound production device, and the high-frequency acoustic performance of the electronic apparatus is thus better.
