Abstract

The invention discloses a loudspeaker module, and relates to the technical field of electroacoustic products. The loudspeaker module comprises a module shell, and a loudspeaker monomer is contained in the module shell and divides a whole module inner cavity into a front acoustic cavity and a back acoustic cavity; a sound absorption cavity is arranged in the back acoustic cavity in a hanging mode and filled with sound absorption materials, a shell of the sound absorption cavity is provided with a filling opening used for filling the sound absorption materials, and the filling opening is covered with a sealing sheet; the two opposite sides of the shell are each provided with a net-shaped part, and gaps are formed between the two sides, provided with the net-shaped parts, of the shell and the module shell respectively. The loudspeaker module solves the technical problem that in the prior art, the sound absorption effect of sound absorption materials of a loudspeaker module is poor. The loudspeaker module has the advantages that the sound absorption function of the sound absorption materials can be fully achieved, the sound absorption effect is good, F0 is lower, the acoustic performance is obviously improved, and the sound quality is better.

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 of portable electronic equipment, which is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. Existing speaker modules usually include a shell, in which a speaker unit is accommodated, and the speaker unit divides the entire module inner cavity into two cavities, a front acoustic cavity and a rear acoustic cavity. As the volume of the cavity of the speaker module becomes smaller and smaller, in order to make the speaker module perform well, reduce the F0 (resonant frequency) of the module, and improve the sound quality, technicians usually add sound absorption in the rear sound cavity Material, the sound-absorbing material will absorb part of the sound energy, which is equivalent to expanding...
