Abstract

The embodiment of the invention relates to the acoustic and electric field, and discloses a loudspeaker box. The loudspeaker box comprises a shell and a sound emission unit accommodated in the shell,wherein the sound emission unit comprises a vibrating film used for emitting sound via vibration, the vibrating film and the shell are arranged at an interval to form a front sound cavity, the loudspeaker box also comprises a sound emission channel communicating with the outside via the front sound cavity, the front sound cavity and the sound emission channel jointly form a front cavity of the loudspeaker box, at least two through holes penetrating through the shell are formed at the position, corresponding to the front cavity, of the shell, each through hole is covered with an elastic wall, the elastic walls covering the at least two through holes have different resonant frequencies, and each elastic wall is used for absorbing the vibration of different frequency bands. The loudspeaker box can improve the problem of sound distortion, and enhance acoustic performance.

Description

technical field [0001] The embodiments of the present invention relate to the field of sound and electricity, and in particular to a speaker box for portable electronic products. Background technique [0002] With the advent of the mobile Internet era, the use of smart mobile devices is increasing. Among many smart mobile devices, sound playback is one of the most important functions, and this function is usually implemented by a speaker box. [0003] The speaker box in the prior art includes a housing, and a sounding unit housed in the housing. The sounding unit includes a diaphragm for vibrating and sounding. The diaphragm is spaced apart from the housing to form a front The sound cavity, the speaker box further includes a sound guide channel communicating the front sound cavity with the outside world, the front sound cavity and the sound guide channel together constitute the front cavity of the speaker box. [0004] However, the inventors of the present invention have f...
