[0023] Specifically, the shell 100 is elliptical as a whole, and a speaker unit 400 is installed at the upper position of the inner cavity 110. A fixing frame 500 is arranged at the bottom to fix other components. The PCB board 200 is fixed on one side of the fixing frame 500. A certain accommodating space is formed between the speaker unit 400 and the fixing frame 500, and the space is used to accommodate the battery module 300. The position of the battery module 300 is fixed by attaching to the fixing frame 500, thereby making full use of the space of the installation cavity 110 from top to bottom; under the support of the fixing frame 500, the battery module 300 is located in the middle of the inner cavity, the overall center of gravity of the speaker is centered, the vibration is balanced during operation, the positions of the components are reasonably arranged and the space is fully utilized; the side wall of the shell 100 is made of a material with a light-transmitting effect. In this embodiment, the jade material with a light-transmitting effect is preferably used. The outer wall of the shell 100 is made of jade. The special material of jade makes the sound quality good. At the same time, its light transmittance can better display the lighting effect, or the ceramic material is used to process the side wall through the engraving process to achieve the light transmittance effect, so as to better display the lighting effect. Since the lighting component of the PCB board is located at the edge, when the light-emitting component 210 is working, it can shine from bottom to top to the light-transmitting side wall, and the lighting effect of the side wall is more transparent. The side wall of the shell 100 can display the lighting effect coordinated with the music, so that it is not easy to be blocked by other components in the installation cavity 110 with a smaller space, ensuring a better lighting effect; in addition, the inner side of the fixed frame 500 forms the installation space of the diaphragm 600, and is connected to the outside of the shell 100, which efficiently utilizes the space while the positions of the components are reasonably arranged, the overall structure is simple, and it is easy to produce.

[0024] Furthermore, an annular groove 120 is provided at the top of the inner wall of the housing 100, and the edge of the speaker unit 400 is hung on the annular groove 120.
