Abstract

Embodiments of the present invention provide a loudspeaker module and electronic equipment. The loudspeaker module includes: a module casing, a loudspeaker monomer and sound-absorbing particles; the loudspeaker monomer divides the inner cavity surrounded by the module casing into a front sound chamber and a rear sound chamber; the rear sound chamber has a A filling area separated by a wall, the filling area has ports capable of realizing air circulation; the sound-absorbing particles are filled in the filling area and confined in the filling area; the ports of the filling area are connected to the mold A gap is formed between the inner walls of the group housing, and sound-absorbing cotton is arranged in the gap. The technical solution provided by the invention can reduce the degree of influence of the resonance caused by the gap on the acoustic performance of the loudspeaker module.

Description

technical field [0001] The invention belongs to the technical field of electroacoustic conversion devices, and in particular, the invention relates to a loudspeaker module and electronic equipment. Background technique [0002] A speaker is a device that converts electrical energy into sound energy, and is widely used in electronic devices such as mobile phones and computers. In the prior art, when a speaker is assembled with a terminal device, it is usually necessary to place a speaker unit in an external casing and assemble it into the terminal device in the form of a module. [0003] In the prior art, a retaining wall is usually arranged on the lower shell of the speaker, and mesh cloth is melted on the retaining wall to form a filling space for sound-absorbing particles. In order to ensure that the airflow can touch the sound-absorbing particles through the mesh, a certain slit is formed between the mesh and the upper shell of the module. The existence of the slit easi...
