Abstract: A speaker in which an end of a magnetic assembly close to the diaphragm has a magnetic gap. A coil is wound around a coil former, and at least a portion of the coil is located in the magnetic gap. A connecting member is arranged on a side of the coil former close to a side wall of the accommodating cavity. An annular first damper is arranged between the coil former and the connecting member. The first damper is close to an upper end of the coil and is distal from a lower end of the coil. An annular second damper is arranged between the connecting member and the side wall of the accommodating cavity. The second damper is close to the lower end of the coil and is distal from the upper end of the coil.
