ABSTRACT:
Speaker damper (12) used in a speaker including frame (5), magnetic circuit (1) coupled to frame (5), voice coil unit (2) inserted into magnetic gap (8) provided in magnetic circuit (1), and diaphragm (3) coupled to frame (5) and voice coil unit (2) at its outer and inner peripheral ends, respectively. Speaker damper (12) is coupled to voice coil unit (2) and frame (5) at its inner and outer peripheral ends, respectively, and has first supporting portion (10) having a first elastic modulus at its inner peripheral end and second supporting portion (11) having a second elastic modulus different from the first elastic modulus at the outer peripheral side of first supporting portion (10). This configuration can reduce the distortion of a speaker, even if the amplitude amount of voice coil unit (2) becomes large, and a large load is not applied to vibrating voice coil unit (2).
