Abstract

The invention discloses a sound production device and electronic equipment, the sound production device comprises a shell and a sound production unit, the shell is provided with an accommodating cavity and a sound outlet communicated with the accommodating cavity, the sound production unit is arranged in the accommodating cavity and divides the accommodating cavity into a front sound cavity and a rear sound cavity, and the sound outlet communicates the front sound cavity with the outside; the shell is further provided with a buffer cavity and a sound transmission hole communicated with the buffer cavity and the front sound cavity. The invention aims to provide a sound production device capable of effectively improving acoustic performance and hearing feeling, and the sound production device can effectively inhibit a polarization phenomenon.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a sound generating device and electronic equipment using the sound generating device. Background technique [0002] With the rapid development of science and technology, people have higher and higher requirements for the sound quality of electronic equipment, and the volume of sound-generating devices in electronic equipment is affected by the appearance and structure of electronic equipment, and its volume is also getting smaller and smaller. As an important and indispensable functional component of electronic equipment, the sound-generating device is an important part of the thin and light design of electronic equipment, so it is extremely important for the thin and light design of the sound-generating device. [0003] In the related art, the speaker box for side sounding includes a sounding unit housed in the housing, the sounding unit includes a diaphragm f...
