Sounder

Abstract

The invention provides a sounder. The sounder comprises a basin frame, a magnetic circuit system and a vibration system, the magnetic circuit system and the vibration system are contained in the basin frame, the vibration system comprises a vibrating diaphragm and a voice coil driving the vibrating diaphragm to vibrate and produce sound, the magnetic circuit system comprises a lower clamping plate and a magnetic steel assembly stacked on the lower clamping plate, and a rear sound cavity of the sounder is defined by the vibrating diaphragm, the basin frame and the magnetic circuit system. A leakage hole communicated with the rear sound cavity and the external space of the sounder is formed in the basin frame, the sounder further comprises an isolation net which covers the leakage hole and is integrally injection-molded with the basin frame, the isolation net comprises a central part opposite to the leakage hole and a fixing part which is located on the periphery of the central part and is fixedly connected with the basin frame, and the fixing part comprises an embedded part embedded in the basin frame; the basin stand comprises a covering part covering the embedded part, and the covering part is provided with a recessed part which is recessed from the surface, away from the embedded part, of the covering part to the direction close to the embedded part and is connected with the embedded part. Compared with the prior art, the sound generator provided by the invention has the advantage that the binding force between the isolation net and the basin stand is stronger.

Description

【Technical field】 [0001] The invention relates to the field of acoustic-electric conversion, in particular to a sound generator. 【Background technique】 [0002] With the rapid development of mobile communication technology in recent years, consumers are increasingly using mobile communication devices with voice functions, such as portable phones, handheld game consoles, laptop computers, laptop computers, multimedia players and through Other devices that communicate over public or private communication networks. And sound generator is as the playing device of voice, and its design quality directly influences the performance of mobile communication equipment. [0003] In related technologies, the sound generator includes a vibration system, a magnetic circuit system that drives the vibration system to vibrate and sound, and a basin frame that accommodates the vibration system and the magnetic circuit system. With the diaphragm of the vibration system as the boundary, the in...
