Abstract

The invention discloses a sound box, comprising a first box body and a second box body. The first box body and the second box body are not communicated. A loudspeaker is set on a front panel of the first box body. A circuit board electrically connected with the loudspeaker is set in the second box body. A sound box light is set on the loudspeaker. The sound box light is electrically connected withthe circuit board through a lead wire. The sound box light comprises a central board, an annular holder, connection bridges, a drive board and an LED light bar. The annular holder is set at the periphery of the central board. The central board is connected with the annular holder through the connection bridges. The LED light bar is fixed on the annular holder. LED lights are set on the LED lightbar at intervals. The drive board is fixed on the central board. A drive circuit for driving the LED light bar to work is set on the drive board. According to the sound box provided by the invention,the frequency of opening a voice cavity part of the sound box can be reduced, the leakproofness of the sound box is improved to the greatest extent, the sound quality of the sound box is ensured, andthe service life of the sound box is improved finally.

Description

technical field [0001] The invention relates to a sound box, in particular to a sound box. Background technique [0002] At present, most speakers arrange the speaker and the circuit board in the same sound cavity. Although this arrangement can facilitate assembly and processing, when there is a problem with the components in the speaker and need to be reworked, repaired or replaced, it must be Open the sound cavity of the speaker to perform related operations; because the airtightness of the sound cavity of the speaker has a major impact on the sound quality of the speaker, when the box of the speaker is disassembled and assembled many times, the airtightness of the sound cavity of the speaker will be greatly reduced, thus affecting the sound quality of the speaker. The sound quality will eventually affect the service life of the speaker; [0003] In addition, in order to enable the speakers to produce a stronger bass effect, most audio speakers often use an inverted struc...
