A multi-function speaker, comprising:
- a frame having a housing space, comprising:
- two first side walls oppositely disposed to each other;
- two second side walls oppositely and configured to connect two first side walls respectively;
- a vibration system accommodated in the housing space;
- a magnetic circuit system accommodated in the housing space, which comprises:
- a lower plat;
- a primary magnet disposed on the lower plate;
- two secondary magnets disposed on both opposite sides of the primary magnet in a direction parallel to the second side wall;
- an upper plate disposed on the secondary magnet, the upper plate comprises:
- a main body portion disposed on the secondary magnet;
- and
- protrusions which protrude from both ends of the main body portion in the vibration direction and distal from the secondary magnet;
- an elastic body fixed to the frame and configured to suspend the magnetic circuit system in the housing space, the elastic body comprises two elastic pieces of the same structure, and the elastic piece includes:
- a first fixed portion fixedly connected to the first side wall;
- a second fixed portion fixedly connected to the protrusion;
- and
- an elastic portion connected the first fixed portion and the second fixed portion, wherein the elastic portion comprises two first elastic portions extending from two opposite ends of the first fixed portion and a second elastic extending from one end of the first elastic portion, the second elastic portion comprises a first elastic arm proximal to the second side wall, a second elastic arm proximal to the primary magnet and a first connected arm configured to connect the first elastic arm and the second elastic arm, one end of the first elastic arm distal from the first connected arm connects the first elastic portion, one end of the second elastic arm distal from the first connected arm is connected to the second fixed portion.
