Abstract

The invention discloses a sound generation device, and the device comprises a vibration system and a magnetic circuit system. The vibration system includes a diaphragm having a first surface and a second surface opposite to the first surface. The magnetic circuit system is located at a side of the second surface of the diaphragm. A part, communicated with a space at a side of the first surface, ofthe sound generation device is provided with a first sound generation hole, and a part, communicated with a space at a side of the second surface, of the sound generation device is provided with a second sound generation hole. A waterproof gas-permeable member is disposed on the second sound generation hole. According to the technical solution of the invention, the device can realize the two-waysound generation function of the sound generation device.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a sound generating device. Background technique [0002] Terminal devices (such as mobile phones, cordless phones, notebook computers, digital cameras, bluetooth earphones, etc.) have been ubiquitous in people's daily life. For the loudspeaker, an important part of the end device, the diaphragm radiates sound energy in both forward and reverse directions during operation. Generally, the loudspeaker only utilizes the sound wave energy radiated in the forward direction, but does not make good use of the sound wave energy radiated in the reverse direction. Therefore, the existing loudspeakers generally can only realize the one-way sound emitting function, which restricts the application of the loudspeakers to a large extent. Contents of the invention [0003] The main purpose of the present invention is to provide a sounding device, aiming at realizing the two-way sounding ...
