Abstract:
PROBLEM TO BE SOLVED: To provide a speaker which can reduce the number of components to reduce cost by integrally molding at least a diaphragm and a damper thereby simplifying a configuration, and which has wide reproduction frequency band even though it is the small-sized speaker with small diameter diaphragm, withstands a high input and is high in reliability and small in size.
SOLUTION: In the speaker 1 formed by arranging the damper in a voice coil bobbin 8 on which a voice coil 7 is wound, the damper 10 and a vibration part 11 are integrally formed to obtain a vibration system 9, the damper 10 of the vibration system 9 is fitted onto a magnetic circuit 5 in the voice coil bobbin 8, and the voice coil bobbin 8 is maintained in the magnetic gap of the magnetic circuit 5.
