Abstract

The invention discloses an acoustic switch and a sound production device. The acoustic switch comprises a shell, a bearing piece, an execution assembly and a driving assembly, wherein the shell is provided with an accommodating cavity; the bearing piece is arranged in the accommodating cavity and connected with the shell, the accommodating cavity is divided into a first accommodating cavity and a second accommodating cavity by the bearing piece, and the first accommodating cavity and the second accommodating cavity are respectively communicated with the outside; the execution assembly is movably arranged in the first accommodating cavity and is provided with a closing position for moving to seal and isolate the first accommodating cavity and the second accommodating cavity in the direction close to the bearing piece and an opening position for moving to communicate the first accommodating cavity and the second accommodating cavity in the direction away from the bearing piece; and the driving assembly is arranged in the second accommodating cavity and connected with the execution assembly so as to drive the execution assembly to move to the closing position or the opening position in a reciprocating mode. According to the acoustic switch and the sound production device, the switching of acoustic channels is achieved, the structure is simple, and implementation and operation are convenient.

Description

technical field

[0001] The invention relates to the field of acoustic-electric conversion, in particular to an acoustic switch and a sound generating device. Background technique

[0002] With the continuous improvement of living standards, people's demand for sound is also increasing. In recent years, in order to meet the sound needs of users, sound-generating devices on the market, especially earphones, hearing aids, wearable devices that can emit sound, and electronic products that can emit sound, have continuously improved their performance.

[0003] At present, there are two types of in-ear earphones on the market. One is that the ear canal and the ear canal are not sealed. The low-frequency acoustic channel has always existed, and the active noise reduction effect of the headset will be weakened or the active noise reduction will be enhanced by greatly increasing the sensitivity of the low-frequency sound unit, which will cause great pressure on the user's eardrum. ...
