Document Type and Number:
WIPO Patent Application WO/2021/056899
Kind Code:
A1
Abstract:
Disclosed is a sound generation device, comprising a housing, a magnetic circuit system and a vibration system being mounted on the housing. The vibration system is conducted with an external circuit by means of a signal access terminal arranged on the housing, and the vibration system comprises a vibrating diaphragm assembly, a voice coil assembly and a centering disk, both the voice coil assembly and the centering disk being fixedly connected to the vibrating diaphragm assembly in the vibration direction of the sound generation device, and the centering disk being located outside the voice coil assembly in the direction perpendicular to the vibration direction of the sound generation device; and the magnetic circuit system is provided with a wire passing portion, a lead wire connected to the voice coil assembly passing through the magnetic circuit system and extending to the signal access terminal to be electrically connected to the signal access terminal. The technical effect of the present invention is that the structure of the sound generation device reduces the height of the sound generation device, and simplifies the process of assembling the sound generation device.
