Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] Please see Figs. 1-4 In this embodiment of the present invention, a vibrating horn includes a housing 1 and a sound-producing component 2. The housing 1 includes an upper cover 11 and a lower cover 12, both of which are hollow structures with one end closed and the other end open.

The sound-producing component 2 includes a voice coil 21, a U-shaped iron 22, a magnet 23, a bearing 24, a washer 25, and a first spring. The first spring 26 and the second spring 27 are disposed in the cavity and below the upper cover 11. The voice coil 21 is disposed in the cavity and below the voice coil 21. The lower end of the voice coil 21 extends into the U-iron 22. The magnet 23 is disposed in the U-iron 22. The bearing 24 passes through the magnet 23. Both ends of the bearing 24 protrude from the U-iron 22 and are respectively connected to the upper cover 11 and the lower cover 12. The first spring 26 and the second spring 27 are respectively disposed at both ends of the bearing 24. The first spring 26 is located above the magnet 23 and the second spring 27 is located below the U-iron 22. The washer 25 is disposed between the magnet 23 and the first spring 26.
[0022] When an audio signal passes through the voice coil 21, an alternating magnetic field is generated within it. This causes the U-shaped iron 22 to magnetically cut against the magnet 23, and the magnet moves in accordance with the audio signal, thus causing the horn to vibrate. During operation, the heat generated by the electrical signal passing through the voice coil 21 is dissipated into the surrounding environment through the heat dissipation channel 14 and the first heat dissipation hole 15, preventing heat buildup, improving heat dissipation, and extending the horn's lifespan.
