[0019] Embodiment 1

[0020] In this embodiment, a sound cavity structure module is proposed, which can be applied to a television and can alleviate the vibration and sound problems.

[0021] Such as Figure 1 And Figure 2As shown, in an embodiment of the present utility model, the sound cavity structure module of the present utility model includes a bottom shell 1, a face shell 2, a first speaker 3, a second speaker 4, and a resistance amplifier 5. The face shell 2 is ultrasonically welded to the bottom shell 1, and the face shell 2 and the bottom shell 1 enclose an installation cavity. Specifically, a plurality of positioning posts can be provided between the face shell 2 and the bottom shell 1. Through the plurality of positioning posts, the face shell 2 and the bottom shell 1 can be connected together, and ultrasonic welding can be further performed at the positions of the positioning posts, thereby reducing the cost of gluing and manual gluing. Ultrasonic welding can also be performed at other outer edge contact positions between the face shell 2 and the bottom shell 1 according to requirements. The first speaker 3, the second speaker 4, and the resistance amplifier 5 are all installed in the installation cavity. In the present utility model, the first speaker 3 can be a high-frequency speaker, and the second speaker 4 can be a low-frequency speaker. The face shell 2 is provided with a first opening and a second opening, and the bottom shell 1 is provided with a third opening. The third opening is correspondingly arranged with the second opening. One side of the first speaker 3 extends into the first opening, the first side of the second speaker 4 extends into the second opening, and the second side of the second speaker 4 extends into the third opening. The first speaker 3 is connected to the resistance amplifier 5, and the high-frequency speaker is connected to the resistance amplifier 5, which can alleviate the problem of vibration noise caused by excessive power. Both the first speaker 3 and the second speaker 4 are connected to an electronic connector 6. The electronic connector 6 passes through the face shell 2 and the bottom shell 1. Glue can be applied at the position where the electronic connector 6 passes through the face shell 2 and the bottom shell 1 for further sealing. A plurality of reinforcing ribs 7 are respectively provided at the left and right rear parts of the second speaker 4. The plurality of reinforcing ribs 7 are all arranged on the face shell 2. The second side of the second speaker 4 passes through the plurality of reinforcing ribs 7 and extends into the third opening. In the present utility model, the plurality of reinforcing ribs 7 are specifically four. Two of them are spaced apart at the left part of the second speaker 4, and two of them are spaced apart at the right part of the second speaker 4. The four reinforcing ribs 7 correspond to the second speaker 4 front and back. The second side of the second speaker 4 specifically passes through the exact center of the four reinforcing ribs 7 and then extends into the third opening. The setting of the reinforcing ribs 7 can reduce the risk of vibration noise. The reinforcing ribs 7 can prevent the overall face shell 2 and other components from shrinking inward, avoiding insufficient space and thus generating vibration noise. A silicone buckle 8 is respectively provided at the left and right parts of the face shell 2. The silicone buckle 8 is an anti-vibration silicone buckle 8, which can effectively adjust the problem of vibration noise generated by the present utility model due to up-and-down and left-and-right swinging during operation, and can effectively alleviate the vibration noise.
