Abstract

The invention discloses a loudspeaker module. The loudspeaker module comprises a module shell which is equipped with a containing chamber; a loudspeaker assembly which is arranged in the containing chamber, wherein the containing chamber is partitioned into a front sound cavity and a rear sound cavity by the loudspeaker assembly; and non-foaming sound absorption particles with multi-level pore channel structures. The non-foaming sound absorption particles are filled in the rear sound cavity. The non-foaming sound absorption particles are formed by bonding zeolite raw powder particles. The non-foaming sound absorption particles are equipped with pore channels of three different pore diameter ranges of micropores, mesopores and macropores. The pore diameter range of the micropores is 0.3-0.9 nanometers. The pore diameter range of the mesopores is 2-40 nanometers. The non-foaming sound absorption particles are equipped with doping elements. The doping elements comprise at least one of boron, ferrum, titanium, potassium, calcium, stannum, cesium, germanium, magnesium, sodium and titanium.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular 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 parts are foamed foams, s...
