[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present invention provides a technical solution: a novel sound cavity speaker, including an installation housing 1, a lower cover 101 and a terminal piece body 2. A lower cover 101 and a terminal piece body 2 are provided on one side of the installation housing 1. A magnet body 3, a voice coil body 301, a pole piece body 302 and a sound film body 303 are arranged inside the installation housing 1. The side of the installation housing 1 away from the lower cover 101 is connected to the cover plate 4 through a locking bolt 402. A dust-proof film 401 is connected to the middle of the cover plate 4. An installation groove 5, a guide groove 505 and an insertion slot 6 are opened inside the installation housing 1. The inside of the installation groove 5 is elastically connected to an abutting block 502 through a connecting spring 501. A top of the terminal piece body 2 is connected to an insertion block 601;

[0022] One side of the abutting block 502 is slidably connected to the guide groove 505 through a guide block 504. One side of the terminal piece body 2 is inserted into the installation groove 5, and the insertion block 601 at the top of the terminal piece body 2 is inserted into the insertion slot 6. A pushing block 503 is connected to the top of the abutting block 502. The internal dimension of the voice coil body 301 matches the external dimensions of the magnet body 3 and the pole piece body 302. The installation grooves 5 are symmetrically arranged about the central axis of the installation housing 1.

[0023] During specific implementation, to avoid the problem of the terminal block body 2 being extruded and falling off, when installing the terminal block body 2, through the pushing block 503 on the top of the abutting block 502, the abutting block 502 and the guiding block 504 on one side of the abutting block 502 are pushed along the guiding block 504 towards the side where the connecting spring 501 is located. After the inserting block 601 on the top of the terminal block body 2 is placed into the installation groove 5 and inserted into the inserting groove 6, the pushing block 503 is released. The abutting block 502 can then be reset along the guiding groove 505 under the action of the connecting spring 501 and abut against the inserting block 601 to limit the inserting block 601. Among them, the setting of the guiding block 504 and the guiding groove 505 can improve the stability of the abutting block 502 during movement, and the setting of the pushing block 503 facilitates the pushing of the abutting block 502. This new type of sound cavity speaker can further limit the inserted and limited inserting block 601, effectively reducing the probability of the inserting block 601 falling off from the inserting groove 6 and improving the stability of the sound cavity speaker during use.

[0024] Refer to Figure 1 and Figure 4 As can be seen, a positioning mechanism 7 is provided inside the installation groove 5.

One end of the reset spring 702 is connected to a positioning block 703. A positioning groove 704 is opened inside the installation housing 1, and the positioning block 703 is inserted into the positioning groove 704.

[0025] During specific implementation, to further enhance the stable effect when the sound cavity speaker works, after the abutting block 502 abuts against the inserting block 601, the installer adjusts the position of the abutting block 502 until the groove 701 inside the abutting block 502 is aligned with the positioning groove 704. At this time, the positioning block 703 in the groove 701 will pop out under the action of the reset spring 702 and be inserted into the positioning groove 704 to limit the position of the abutting block 502. This new type of sound cavity speaker is provided with a positioning mechanism 7, which can further enhance the limiting effect on the inserting block 601 and has a better anti-loosening effect.

[0026] In summary, when using this new type of sound cavity speaker, during operation, through the resonance and reflection of the magnet body 3, voice coil body 301, pole piece body 302, and sound film body 303 inside the installation housing 1 and the lower cover 101, and under the protection of the cover plate 4 and the dust-proof film 401, the sound quality and volume of the sound are improved.
