[0001] The utility model relates to sound manufacturing technical field, especially a pot-shaped baffle loudspeaker box. BACKGROUND

[0002] The baffle loudspeaker box has simple structure and is convenient to manufacture.

[0003] At present, the materials used for manufacturing the baffle loudspeaker box are mostly wood boards or wood composite boards, and the loudspeaker is fixed by opening holes.

[0004] Although the traditional baffle loudspeaker box has certain advantages in theory, its defects are still very obvious.

[0005] Firstly, no matter how large the area of the baffle is, it is still impossible to realize true acoustic short circuit.

[0006] Secondly, the baffle is only about 20mm thick and has a planar structure, which is easy to resonate.

[0007] Thirdly, the baffle loudspeaker box and the cone-pot loudspeaker are in the same plane, without acoustic reflection and diffraction, so the directivity is poor.

[0008] Fourthly, the appearance is relatively dull and ugly, which is incompatible with the home environment.

[0009] Therefore, how to provide a pot-shaped baffle loudspeaker box to at least partially solve the above-mentioned defects is a technical problem to be solved by those skilled in the art at present. CONTENT OF THE UTILITY MODEL

[0035] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0036] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In the description of the present application, it should be understood that the terms "upper", "lower", "bottom" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation of the present application.

[0038] The present application aims to provide a pot-shaped baffle sound box, which can improve the directivity and sound pressure of the covering area of the sound box, and overcome resonance to a greater extent and effectively reduce resonance strength.

[0039] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0040] Please refer to Figures 1 to 3 The present application provides a pot-shaped baffle sound box, which comprises a pot-shaped baffle 100, a loudspeaker 200 and a support 300; the pot-shaped baffle 100 is in a pot-shaped structure, and a mounting hole is formed in the center of the bottom thereof; the loudspeaker 200 is fixedly installed in the mounting hole; and the support 300 is fixedly installed at the edge back of the pot-shaped baffle 100 and used for supporting the pot-shaped baffle 100.

[0041] Firstly, the pot-shaped baffle 100 in the present embodiment has high strength and stability, can uniformly bear the huge sound pressure after the loudspeaker 200 sounds, effectively reduces resonance strength, and overcomes the shortcoming that the traditional flat baffle sound box is prone to resonance; secondly, the cross section of the pot-shaped baffle 100 is circular, that is, the pot-shaped baffle 100 is composed of cylindrical bodies with different diameters, and this structure is similar to a submarine, a zip-top can and the like, and has particularly strong uniform pressure bearing capacity, can overcome resonance to a greater extent, and is used on a sound box, thereby effectively reducing sound dyeing and further reducing distortion.

[0042] Further, due to the reflection of the pot-shaped structure to the sound of the loudspeaker 200, the sound box directivity is stronger, which is different from the traditional flat panel type baffle sound box. The direction of the pot-shaped baffle 100 is consistent with the front of the loudspeaker 200, and the sound propagating to both sides is reflected and diffracted by the pot-shaped baffle 100, thereby realizing stronger directivity of the sound box and higher sound pressure in the coverage area.

[0043] Further, the pot-shaped baffle 100 better avoids or reduces the sound short circuit phenomenon, and greatly reduces the area of the baffle in the case of pursuing the same sound short circuit effect. The thickness of the baffle of the traditional flat panel type baffle sound box is generally about 10-30 mm, and if it is thicker, it will affect the sound production of the reverse diaphragm of the loudspeaker 200. Moreover, unless the flat panel type baffle is a whole wall, no matter how large the area of the baffle is, it is still impossible to realize true sound short circuit. The sound propagation speed in the air is 340 m / s, and even if the baffle width is 1200 mm (the loudspeaker 200 is installed in the middle), the baffle is only a few millimeters thick, and after 1.7 milliseconds, the sound waves in the two directions of the loudspeaker 200 will short circuit. The edge of the pot-shaped baffle 100 is often a certain depth from the bottom, and more importantly, due to the reflection and diffraction of the sound waves to the side caused by the pot-shaped baffle 100, the sound waves emitted by the reverse diaphragm of the loudspeaker 200 will not converge with the sound waves emitted by the front diaphragm for a long time, thereby avoiding or reducing the sound short circuit phenomenon. Therefore, it can be inferred from the above discussion that if the sound short circuit occurs in the same time, the maximum cross-sectional area of the baffle of the pot-shaped baffle 100 sound box is much smaller than that of the traditional flat panel baffle sound box.

[0044] In summary, these improvements will greatly reduce the distortion of the pot-shaped baffle 100 sound box, reduce the production cost of the pot-shaped baffle 100 sound box, and improve the appearance of the pot-shaped baffle 100 sound box, thereby improving the application scenarios of the pot-shaped baffle 100 sound box.
