Document Type and Number:
WIPO Patent Application WO/2023/179489
Kind Code:
A1
Abstract:
The present application provides a loudspeaker box, comprising a box body, a loudspeaker and 2N passive vibration assemblies, N being a positive integer. The loudspeaker is mounted on an upper box wall of the box body; the 2N passive vibration assemblies are uniformly distributed on the left side and the right side of the loudspeaker; each passive vibration assembly comprises a first passive vibration unit and a second passive vibration unit; the first passive vibration unit is mounted on the upper box wall of the box body; the second passive vibration unit is mounted on a lower box wall of the box body. According to the technical solution of the present application, the passive vibration assemblies are uniformly arranged on the two sides of the loudspeaker, and the first passive vibration unit and the second passive vibration unit of each passive vibration assembly are respectively arranged on the upper box wall and the lower box wall, so that the transmission of vibration energy of the loudspeaker and the passive vibration assemblies to the box body is weakened to the maximum extent, the resonance phenomenon of the box body is effectively weakened, sound radiation can be enhanced, and the bass sound quality of the loudspeaker box is improved.
