Coaxial Speaker

A coaxial speaker, comprising:

• a magnetic circuit system comprising:
• a bottom plate;
• a first magnetic unit comprising a first magnet disposed on the bottom plate and a first yoke attached to the first magnet;
• and
• a second magnetic unit arranged on an inner side of the first magnetic unit and spaced apart from the first magnetic unit for forming a first magnetic gap, comprising a second magnet in an annular shape disposed on the bottom plate, a second yoke attached to the second magnet, a third magnet in an annular shape attached to the second yoke, and a third yoke attached to the third magnet, wherein the second yoke comprises an annular plate sandwiched between the second magnet and the third magnet, and a bending portion bent and extending from an inner edge of the annular plate in a direction away from the second magnet, the third magnet and the third yoke are spaced apart from the bending portion for forming a second magnetic gap;
• a first sounding unit comprising a first diaphragm and a first voice coil locating in the first magnetic gap and driving the first diaphragm for vibrating and emitting sounds;
• and
• a second sounding unit coaxial with and surrounded by the first sounding unit, comprising a second diaphragm and a second voice coil locating in the second magnetic gap and driving the second diaphragm for vibrating and emitting sounds.
