Abstract

The invention discloses a sound production device. The sound production device comprises a magnetic conductive yoke, a shell and a metal net; the shell extends along the edge of the magnetic conductive yoke to form a ring shape, and a leakage port is formed in a gap between the shell and the magnetic conductive yoke; and a metal net covers the leakage port, and a plurality of air holes are formedin the positions, corresponding to the leakage port, of the metal net. According to the technical scheme, the reject ratio of products can be reduced.

Description

technical field [0001] The invention relates to the technical field of sound energy conversion, in particular to a sound generating device. Background technique [0002] In order to realize the full-filling technology of the rear acoustic cavity of the sound-generating device in the related art, a mesh cloth is generally arranged at the leakage port of the sound-generating device, and the mesh cloth and the shell of the sound-generating device are integrally injection-molded or fixed by bonding. [0003] However, because the shape of the mesh itself is difficult to maintain, it is easy to cause misalignment between the mesh and the leakage port during integral injection molding or bonding, which increases the defective rate of the product. Contents of the invention [0004] The main purpose of the present invention is to provide a sound generating device, aiming at reducing the defective rate of products. [0005] In order to achieve the above object, the sounding device ...
