Loudspeaker box with dust preventing and clearing functions

Abstract

The invention discloses a loudspeaker box with dust preventing and clearing functions. The loudspeaker box comprises a loudspeaker box body, wherein a data interface is arranged in the middle of the back of the loudspeaker box body, the loudspeaker box body is internally provided with a support, a speaker is arranged outside the middle of the support, an isolation box is arranged outside the bottom of the support, a memory is arranged on the inner bottom of the isolation box, a controller is arranged beside the memory, and the data interface, the speaker and the memory are electrically connected with the controller. The loudspeaker box has the beneficial effects that an electrostatic generator supplements electric charge for an electrostatic electret board, and dust entering the loudspeaker box is absorbed through an electrostatic precipitation manner, so that the dustproof effect is achieved, and the sound generation effect of the loudspeaker box is guaranteed; and dust on the electrostatic electret board falls into a dust storage bin by stopping supplementing electric charge, and the dust storage bin is pulled out through a handle so as to clean the dust, so that a traditional dust clean manner based on disassembling is replaced, and the loudspeaker box is not disassembled frequently so as not to be damaged.

Description

technical field [0001] The invention relates to the field of sound boxes, in particular to a sound box with dust-proof and dust-cleaning functions. Background technique [0002] A speaker refers to a device that converts an audio signal into sound. In layman's terms, it refers to the built-in power amplifier in the main box of the speaker or the subwoofer box. After the audio signal is amplified, the sound is played back by the speaker itself to make the sound louder. The speaker is the terminal of the entire audio system, and its function is to convert audio power into corresponding sound energy and radiate it into the space. It is an extremely important part of the audio system, responsible for the task of converting electrical signals into acoustic signals for human ears to listen directly to. [0003] The applicant found that there are at least the following technical problems in the prior art: the speaker does not have a dust-proof structure, the external dust easily ...
