The speaker 100 comprises a vibration structure, a magnetic circuit system and a support structure. The vibration structure may comprise a bend ring 120, a voice coil 122, a dustproof cover 124, a damper 126 and a diaphragm 128. The magnetic circuit system may comprise a main magnet 160, a sub-magnet 162, an upper pole piece 164 and a lower pole piece 166. The support structure may comprise a bracket 140. The bracket 140 is used for accommodating the vibration structure and the magnetic circuit system. The speaker of the present disclosure is not limited thereto, and may have more or less components.

In the vibration structure, the radial outer brim of the bend ring 120 is connected to the bracket 140, and its radial inner brim is connected to the diaphragm 128. The radial outer brim of the damper 126 is connected to the bracket 140, and its radial inner brim is connected to the voice coil 122. When an electrical signal (a sound signal) enters the voice coil, the voice coil can vibrate, in a magnetic gap, along the axis of the speaker, and the vibration of the voice coil will drive the vibration of the diaphragm. The connection between the bend ring 120 and the bracket 140 will be described in more detail below.
