PROBLEM TO BE SOLVED: To provide a speaker which reduces labor hours in manufacturing, achieves a high reproduction sound pressure level, and realizes high efficiency.SOLUTION: A speaker includes: a magnetic circuit 10 which is stored in a frame 5 and has a magnetic gap G; a diaphragm 2 supported by the frame; and a voice coil 9 which is connected with the diaphragm 2 through a voice coil fastener 6 and is disposed in the magnetic gap. The voice coil fastener 6 includes: a plate-like body 7 which is provided on the inner surface side of the diaphragm in a lamination state; a coil bobbin 8 fastened to the plate-like body, the coil bobbin 8 where the voice coil is wound around an outer peripheral surface; and support pins 16 which are fastened to the plate-like body and extend in a bottom surface direction of the frame. The frame 5 is provided with support members 15, each of which is connected with the support pin 16, supports the voice coil fastener 6, and may deform in a vibration direction of the diaphragm. |
