Problems solved by technology

However, the dust-proof mesh is usually connected to the cavity by hot-melt, and a separate hot-melt width needs to be made in the cavity, which wastes the cavity filling space, and the strength of the hot-melt connection is unstable, and the dust-proof mesh is easy to fall off and fail

Abstract

The invention discloses a sound production device and a method for making the same. The sound production device comprises a frame with an accommodating space and openings at two ends, a first cover plate which is in covering connection with the opening at one end of the frame, a second cover plate which is in covering connection with the opening at the other end of the frame, an isolation net and a sound producer; the isolation net is connected onto the frame through injection molding; the accommodating space is divided into a front cavity and a rear cavity through the isolation net; the first cover plate, the frame and the isolation net encloses the front cavity; the second cover plate, the frame and the isolation net encloses the rear cavity; the sound producer is accommodated in the front cavity; the sound production device further comprises sound absorption powder which fills the rear cavity; and the sound absorption powder is sealed in the rear cavity through the isolation net. The sound production device provided by the invention has the advantages of excellent low-frequency performance and high reliability.

Description

【Technical field】 [0001] The invention relates to a sounding device, in particular to a sounding device used in portable electronic products and a method for making the sounding device. 【Background technique】 [0002] In the process of rapid development of portable electronic products such as mobile phones, users have increasingly strong requirements on the functionality of products, and thus, the development of sound-generating devices has also accelerated accordingly. [0003] A sound-generating device in the related art includes a housing with a cavity and a sounder unit mounted on the housing. Since the cavity is a closed structure and the volume of the cavity is relatively small, the resonance frequency of the sound-generating device is high, resulting in poor low-frequency performance of the sound-generating device, and it is difficult to play a thick and rich bass. However, the development of miniaturization of sound-generating devices has limited the specifications ...
