Examples

The embodiment of the utility model provides a sound box structure, as shown in fig. 1-4, including casing 1 and loudspeaker 2, casing 1 is last to have seted up first sound chamber 11 and second sound chamber 12, and first sound chamber 11 and second sound chamber 12 are independent cavity separately, and the cross-sectional area of second sound chamber 12 is greater than the cross-sectional area of first sound chamber 11, is provided with the division board in the first sound chamber 11, and the division board separates first sound chamber 11 for left cavity 111 and right cavity 112, and second sound chamber 12, left cavity 111, each fixed at least one loudspeaker 2 that is provided with in the right cavity 112. The sound box body structure with the structure is adopted, wood, plastic or metal materials are selected to manufacture the sound box, and the specific shell 1 is made of the wood, the plastic, the metal materials and the like. When the box body is made of all metal materials, the sound box with the structure can well play the metal attribute of tone quality.

Furthermore, when the thickness of the shell 1 is between 2mm and 10mm, more preferably 5mm, the structural design of the ultrathin wall thickness can better match the original material characteristics, and further ensure the sound plumpness and flexibility. Wherein, the thickness of the shell 1 with the thickness of 5mm can better give consideration to the sound quality and the firmness of the box body.

The first sound cavity 11 is provided with a first cover plate 14, and a sound outlet 141 is formed at a position of the first cover plate 14 corresponding to the loudspeaker 2. The second cover plate 15 is arranged on the second sound cavity 12, a through hole 151 is formed in the second cover plate 15, and the loudspeaker 2 is embedded into the through hole 151. The first cover plate 14 and the second cover plate 15 have a seal structure with the corresponding horn 2. Through the seal structure between this apron and loudspeaker 2, the condition of distortion can be reduced to such sealed design, and then guarantees the audio, finally promotes tone quality. The sealing structure may more specifically be a sealant.

The left and

right chambers

111 and 112 are symmetrically disposed with a partition plate. The horns 2 in the left cavity 111 and the right cavity 112 are both arranged on the side far away from the partition plate. The two horns 2 are arranged relatively far away from each other, so that the structure can reduce the problem of resonance caused by the close distance of the two horns 2.

In consideration of the sound effect, the ratio of the loudspeaker 2 to the sound cavity needs to be adjusted. In the debugging process, on the basis of the sound box body structure of the embodiment, the volume ratio of each sound cavity to the inner loudspeaker 2 is set to be 1.5: 1 to 2:1, the sound effect ratio can be better. The volume ratio of the first sound cavity 11 to the loudspeaker 2 arranged in the first sound cavity is 1.7:1, and the volume ratio of the second sound cavity 12 to the loudspeaker 2 arranged in the second sound cavity is 1.7:1, so that a better sound effect can be presented.

The sound box body structure of the utility model can reduce the resonance problem of the loudspeaker and the shell by designing different sound cavities for the loudspeakers; the thickness and the material of casing after preferred cooperate the structure after the box improves, have guaranteed the plumpness and the pliability of sound, finally realize neither distorting can guarantee the quality again.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
