[0007] A closed frame, the closed frame is installed on the surface of the box body and covers the second speaker, and a buffer belt is provided on the surface of the closed frame, and the buffer belt is arranged in a ring shape;

[0008] A pressing frame, the pressing frame is clamped with the closed frame, the pressing frame and the closed frame clamp a buffer belt, and the buffer belt fills the gap between the pressing frame and the closed frame, thereby improving the stability of the connection between the pressing frame and the closed frame, avoiding the vibration of the pressing frame and the collision with the closed frame, and avoiding abnormal noise problems;

[0009] The dust cover is snap-connected with the closed frame and is located outside the second speaker to protect the second speaker from dust and prevent the dust from affecting the sound quality of the second speaker.

[0010] Furthermore, an upper cover is installed on the top of the box, and a main control board is installed on the inner wall of the upper cover. The main control board can be used to control the volume, mode, switch and other functions of the audio. A display screen is installed on the surface of the upper cover, and the information of the sound source can be viewed through the display screen.

[0011] Furthermore, the surface of the closing frame is provided with a first bayonet, a second bayonet and a third bayonet arranged in a ring, the surface of the clamping frame is provided with a first hook and a second hook arranged in a ring, and the first hook and the second hook are connected to the first bayonet and the second bayonet, and the surface of the dust cover is provided with a third hook connected to the third bayonet, which makes it more convenient to assemble the speakers and also more convenient to disassemble the speakers for cleaning, thereby simplifying the production process of the speakers.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The clamping frame and the closed frame are clamped together by the second hook and the third hook, and a buffer belt is set between the clamping frame and the closed frame. The buffer belt is used to improve the compactness of the clamping frame after assembly, and a cotton block is used to cushion the clamping frame to ensure that the clamping frame does not rub against the closed frame, thereby preventing abnormal noise from occurring after the speaker is assembled.

[0014] (2) The closed frame and the closed cover are assembled and spliced ​​through the box. The closed frame and the closed cover are both arc-shaped. The number of closed frames and closed covers to be used can be determined according to the height of the box. Since the volume of the speaker is changed, the number of speakers can be flexibly adjusted, which is convenient for the production of the speaker. BRIEF DESCRIPTION OF THE DRAWINGS
