Problems solved by technology

However, the current portable electronic terminals are all developing in a thinner and smaller direction, such as Pad (tablet computer), etc., which are getting smaller and thinner, which leads to the inability of the loudspeaker module with a larger volume to be installed in the electronic terminal. Can not meet the needs of increasingly thin and compact electronic terminals

Abstract

The invention discloses a loudspeaker module, which relates to the technical field of electro-acoustic products. It is installed inside an electronic terminal and includes a housing. A vibration system and a magnetic circuit system are accommodated in the housing. The magnetic circuit system includes a The upper pot frame, the magnet and the washer are fixed in sequence in the pot frame, and the position of the side wall of the shell corresponding to the pot frame is provided with a rear sound hole, and the rear sound hole is connected to the inner part of the module. cavity and the inner cavity of the electronic terminal; the upper end of the side wall of the frame corresponding to the rear sound hole is provided with a chamfering plane, and the chamfering plane is set on the side wall of the frame near the One side of the rear sound hole. The loudspeaker module of the present invention solves the technical problems of the loudspeaker module in the prior art, such as large volume and easy distortion of low frequency. Demand, and high stability, long service life.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a loudspeaker module. Background technique [0002] The loudspeaker module is an important acoustic component in a portable electronic terminal, which is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. The loudspeaker module usually includes a casing, in which a speaker unit is accommodated, and the speaker unit includes a vibration system and a magnetic circuit system. The inner cavity of the existing speaker module is divided into two cavities by the vibration system. One is the front sound cavity located in front of the vibration system. The sound is transmitted out; the other is the rear sound chamber located behind the vibration system, the rear sound chamber is a closed cavity, which is used to improve the low-frequency performance of the speaker module and prevent acoustic short circuit. I...
