Abstract

The invention discloses a loudspeaker module and a portable terminal. The loudspeaker module comprises a shell, a sound production monomer, an acoustic transmission separator, a sound absorbing material and a support piece, wherein the shell is provided with an inner cavity; the sound production monomer is accommodated in the inner cavity, and divides the inner cavity into a front cavity and a rear cavity; the acoustic transmission separator is a flake and is accommodated in the rear cavity; a sound absorbing cavity is formed by the acoustic transmission separator and the inner wall surface ofthe shell in an enclosing manner; the sound absorbing cavity is filled with the sound absorbing material; the support piece is arranged between the sound production monomer and the acoustic transmission separator; and the side, which faces towards the sound production monomer, of the acoustic transmission separator is supported by the support piece, so as to form an avoidance gap between the acoustic transmission separator and the sound production monomer. The loudspeaker module disclosed by the invention has effects of ensuring that no collision occurs between the acoustic transmission separator and the sound production monomer and making full use of the space of the rear cavity.

Description

technical field [0001] The invention relates to the field of electroacoustic technology, in particular to a loudspeaker module and a portable terminal. Background technique [0002] The speaker module is an executive device for electronic equipment to realize audio playback. If the height of the installation space allows, a sound-absorbing cavity can be added in the speaker module, and sound-absorbing materials can be filled in the sound-absorbing cavity to improve the low-frequency acoustic performance of the speaker module. . In an existing loudspeaker module, the sound-emitting unit divides the inner cavity of the housing into a front cavity and a rear cavity, and the sound-absorbing cavity is formed by a sound-transmitting spacer arranged in the rear cavity and enclosed by the housing. In order to make full use of the rear cavity Space and to avoid the noise caused by the collision between the sound-transmitting spacer and the sound-emitting unit, it is necessary to ens...
