Abstract

The invention discloses a loudspeaker monomer and a loudspeaker module. The loudspeaker unit comprises a central magnet, a concave hole is formed in the middle area of the central magnet, and the concave hole penetrates through the central magnet in the thickness direction of the central magnet, or the concave hole is a blind hole with the depth extending in the thickness direction of the centralmagnet. According to the technical scheme, the magnetic flux leakage phenomenon can be reduced.

Description

technical field [0001] The invention relates to the technical field of sound energy conversion, in particular to a loudspeaker unit and a loudspeaker module. Background technique [0002] Traditional loudspeakers include a magnetic yoke and a magnet combined with one side of the magnetic yoke, which inevitably makes the magnetic yoke surface and the front cover of the speaker have higher magnetic flux leakage, which is the characteristic of the widely used speakers now. a commonality. Because the speaker has high magnetic flux leakage, when the speaker is placed on the top of the mobile phone or used near a product such as a Pad with a camera, the high magnetic flux leakage will affect the normal operation of the camera. Contents of the invention [0003] The main purpose of the present invention is to provide a loudspeaker unit and a loudspeaker module, aiming at reducing the magnetic flux leakage phenomenon of the loudspeaker. [0004] In order to achieve the above obj...
