Problems solved by technology

[0003] In the prior art, in order to improve the acoustic performance of terminal products, it is often necessary to assemble two acoustic components at the upper and lower ends. There are three main methods: one is to assemble a Receiver at the upper end and an SPK module at the lower end. This method exists The defect of low volume; the second is to assemble an SPK module on the upper and lower ends at the same time. Compared with the first method, the sound effect of this method is better, but the sealed rear cavity will occupy a large space, which is not conducive to the small size of the produc

Abstract

Embodiments of the invention provide a sound production device and electronic equipment. The sound production device comprises a vibration system, a magnetic circuit system, a shell and an antenna, wherein the shell comprises an installation part with at least one open end and a back cavity part which is correspondingly arranged on the outer side of the first side wall of the installation part andis used for forming a rear cavity; the magnetic circuit system and the vibration system are fixed in the installation part; a back sound hole communicating with a magnetic gap in the magnetic circuitsystem and the back cavity is arranged in the position, right opposite to the back cavity, of the first side wall; and the antenna is arranged on the back cavity. According to the embodiments of theinvention, the volume of the sound production device can be reduced while the acoustic performance is ensured, and the antenna can be integrated on the small-volume sound production device in order toimprove the integration level.

Description

technical field [0001] The invention relates to the technical field of sound generating devices. Background technique [0002] With the development of consumer electronic products, the miniaturization design of consumer electronic products has attracted more and more attention. As a component of electronic products, sound generating devices have higher and higher requirements for integrated design. The integrated design of the sound generating device and the antenna has become a trend of technological development. [0003] In the existing technology, in order to improve the acoustic performance of terminal products, it is often necessary to assemble two acoustic components at the upper and lower ends. There are three main methods: one is to assemble a Receiver at the upper end and an SPK module at the lower end. This method exists The defect of low volume; the second is to assemble an SPK module on the upper and lower ends at the same time. Compared with the first method, ...
