Problems solved by technology

However, the flat structure of the micro-speaker module will cause the cavity volume of the rear acoustic cavity to decrease, resulting in an increase in the resonant frequency F0 of the speaker and a decrease in low-frequency sensitivity, which will adversely affect the acoustic performance of the speaker

Abstract

The invention discloses a speaker module. The speaker module is characterized by comprising a module shell, a speaker assembly and aluminum-free silicate zeolite particles, wherein a containing cavity is formed in the module shell; the speaker assembly is arranged in the containing cavity, and the containing cavity is divided into a back vocal cavity and a front sound area by the speaker assembly; the back vocal cavity is filled with the aluminum-free silicate zeolite particles, and the aluminum-free silicate zeolite particles are formed in a way that zeolite raw powder particles are bonded by adhesives; first-stage hole channels are formed in the zeolite raw powder particles, the hole diameter range of the first-stage hole channels is 0.3 to 20 nm, and second-stage hole channels are formed between the zeolite raw powder particles in the aluminum-free silicate zeolite particles. The invention solves the technical problem to provide the speaker module with low resonant frequency.

Description

technical field [0001] The invention belongs to the technical field of loudspeakers, in particular, the invention relates to a loudspeaker module. Background technique [0002] As an energy converter that converts electrical signals into sound signals, the speaker module is an indispensable part of electro-acoustic products. A speaker module is usually composed of a housing and a speaker unit, and the speaker unit divides the inner cavity of the module housing into two cavities, a front acoustic cavity and a rear acoustic cavity. In order to improve the acoustic performance of the speaker module (such as reducing the resonant frequency F0 of the module and expanding the bandwidth), sound-absorbing parts are usually added in the rear acoustic cavity, and the sound-absorbing parts will absorb part of the sound energy, which is equivalent to expanding the volume of the rear cavity, thereby Achieve the effect of reducing the F0 of the module. The traditional sound-absorbing pa...
