The vibration system 1 is suspended on the base frame 2, the vibration system 1 and the base frame 2 form a sound cavity, and the magnetic circuit system 3 is arranged in the sound cavity of the base frame 2;
the voice coil 4 is attached below the vibration system 1; the voice coil 4 is electrically connected to the corresponding driving circuit, receives the electrical signal of the driving circuit and generates magnetic fields with different magnitudes, so as to generate an acting force with the magnetic circuit system 3 to drive the vibration system 1 to vibrate.
The elastic pieces 5 are arranged at four corner positions of the magnetic circuit system 3, connected between the vibration system 1 and the magnetic circuit system 3, and provide elasticity for deformation of the vibration system 1. In this embodiment, when the voice coil 4 is not driven by an electric signal, the elastic member 5 is not compressed by the vibration system 1 and the magnetic circuit system 3, is not stretched by the vibration system 1 and the magnetic circuit system 3, and is in a state of not receiving an external force. When the vibration system 1 vibrates, the elastic member 5 provides a force to the vibration system 1 in a direction opposite to the vibration direction of the vibration system 1, and prevents the vibration system 1 from colliding with the magnetic circuit system 3 or separating from the base frame 2 in the case of an excessive amplitude or the like of the vibration system 1. Meanwhile, as the vibration system 1 needs to overcome the reverse acting force of the elastic part 5 in the vibration process, the acting force of the voice coil 4 on the vibration system 1 can be increased, and a better sound effect is brought.

In this embodiment, the diaphragm and the dome are directly adopted in the prior art in the field, and are not related to the core improvement point of the present invention, and are not specifically described herein. If the vibration system 1 adopted in the embodiment only has a vibrating diaphragm, the elastic member 5 is connected between the vibrating diaphragm and the magnetic circuit system; if the vibration system 1 is composed of a diaphragm and a dome, the elastic member 5 is connected between the dome and the magnetic circuit system.
