Loudspeaker box

Abstract

The invention provides a loudspeaker box. The loudspeaker box comprises an upper cover, a lower cover and a single sound production unit. The lower cover and the upper cover enclose an accommodating space. The single sound production unit is arranged in the accommodating space. The lower cover comprises a top wall, a side wall and a supporting wall. The supporting wall is arranged around the single sound production unit. The accommodating space is divided into a front cavity and a rear cavity by the single sound production unit. A sound outlet hole is formed in the side wall. The lower cover further comprises a surrounding wall. The loudspeaker box further comprises a sealing assembly covering the enclosure bulkhead. A resonant cavity is defined by the surrounding wall, the supporting walland the sealing assembly. A through hole is formed in the supporting wall, the resonant cavity is communicated with the front cavity through the through hole, the sealing assembly comprises a cover plate fixed to the surrounding wall and a ventilation isolation piece arranged on the cover plate, the ventilation isolation piece and the cover plate are bonded and fixed through a glue layer, a leakage hole is formed in the sealing assembly, and the leakage hole is communicated with the rear cavity through the ventilation isolation piece. According to the loudspeaker box, the resonant cavity increases the cavity volume of the front cavity, the high-frequency acoustic performance is improved, and the leakage hole in the sealing assembly can balance the air pressure in the loudspeaker box.

Description

technical field [0001] The invention belongs to the technical field of electroacoustics, in particular to a speaker box. Background technique [0002] With the rapid development of science and technology, audio equipment is also developing rapidly. People have higher and higher functional requirements for audio equipment. For speaker boxes, more and more people put forward higher requirements for their audio performance. In related technologies, the space of the front cavity only includes the area directly facing the sounding unit and the area of ​​the sound guide channel, which is relatively single, which makes the high-frequency frequency response too high, resulting in poor sound quality such as harsh sound, sharp lip-tooth sound, or resonance frequency It falls in the sensitive frequency band of piano sound, which leads to poor quality of piano sound.
