Abstract

The present disclosure provides a sound system. The sound system includes a box body and a loudspeaker arranged in the box body. An internal space of the box body is partitioned into a first chamber and a second chamber by a partition board in a sounding vibration direction of the loudspeaker. A vibration side of the loudspeaker is intercommunicated with the first chamber, and a side of the loudspeaker opposite to the vibration side is intercommunicated with the second chamber. At least one of the first chamber and the second chamber is intercommunicated with the outside.

First claim

What is claimed is:

1. A sound system, comprising a box body and a loudspeaker arranged in the box body, wherein an internal space of the box body is partitioned into a first chamber and a second chamber by a partition board in a sounding vibration direction of the loudspeaker, a vibration side of the loudspeaker is intercommunicated with the first chamber, a side of the loudspeaker opposite to the vibration side is intercommunicated with the second chamber, and at least one of the first chamber and the second chamber is intercommunicated with the outside;
the first chamber is intercommunicated with the outside via a sound wave transmission channel penetrating through a side wall of the box body, and the second chamber is a hermetic chamber; and
a cross-sectional area of the sound wave transmission channel is smaller than an area of the vibration side of the loudspeaker.

2. The sound system according to claim 1 , wherein the sound wave transmission channel is arranged in the first chamber, the loudspeaker is arranged in the second chamber, and the sound system further comprises a resonance cover plate, which is arranged at a position on the exterior wall of the first chamber and corresponding to the vibration side of the loudspeaker.

3. The sound system according to claim 2 , wherein the resonance cover plate comprises a metallic plate or a ceramic plate.

4. The sound system according to claim 1 , wherein the loudspeaker is embedded into and fixed on the partition board.

5. The sound system according to claim 4 , further comprising a resonance cover plate, wherein a mounting hole is arranged at a position on the box body of the sound system and corresponding to the vibration side of the loudspeaker, and the resonance cover plate is mounted in the mounting hole.

6. The sound system according to claim 5 , wherein the resonance cover plate comprises a metallic plate or a ceramic plate.

7. The sound system according to claim 1 , wherein the first chamber and the second chamber resonate to sound when the loudspeaker generates a vibration.

8. The sound system according to claim 1 , wherein the partition board serves as a holder for mounting the loudspeaker.

9. The sound system according to claim 4 wherein the sound wave transmission channel is arranged in the first chamber, the loudspeaker is arranged in the second chamber, and the sound system further comprises a resonance cover plate, which is arranged at a position on the exterior wall of the first chamber and corresponding to the vibration side of the loudspeaker.

10. The sound system according to claim 9 , wherein the resonance cover plate comprises a metallic plate or a ceramic plate.

11. The sound system according to claim 2 , wherein the loudspeaker is embedded into and fixed on the partition board.

12. The sound system according to claim 11 , further comprising a resonance cover plate, wherein a mounting hole is arranged at a position on the box body of the sound system and corresponding to the vibration side of the loudspeaker, and the resonance cover plate is mounted in the mounting hole.

13. The sound system according to claim 12 , wherein the resonance cover plate comprises a metallic plate or a ceramic plate.

14. The sound system according to claim 4 , wherein the first chamber and the second chamber resonate to sound when the loudspeaker generates a vibration.

15. The sound system according to claim 4 , wherein the partition board serves as a holder for mounting the loudspeaker.
