[0002] With the development of science and technology, people's demands for the functions of electronic devices are becoming more and more diversified. In devices or furniture that come into contact with the human body, such as smart beds, massage chairs, and seats of new energy vehicles, there may be a demand for vibration functions with music and accompanying music. The pistols of game consoles have a certain recoil vibration and gunshot sounds when shooting in the game. Such demands are used to enhance the product experience.

[0003] Existing speakers have some problems in practical application, such as:

[0004] 1. The magnetic circuit is fixed on the basin frame, and the speaker has no vibration function when it sounds;

[0005] 2. The speaker has only one spring wave, and the anti-polarization is weak;

[0006] 3. Only one side of the cone is involved in the vibration, and the back side is sacrificed and unused, resulting in low sound energy efficiency;

[0007] 4. When the speaker is working, only the voice coil pushes the cone to make sound, while the magnetic circuit is fixed and does not participate in pushing the air to make sound, so the sound has no enhancement effect. Summary of the invention
