PROBLEM TO BE SOLVED: To provide a high-performance speaker which can be small-sized and thinned but improves sound pressure frequency characteristics.SOLUTION: A speaker 1 comprises a coupling member 8 which is coupled to a rear side of a diaphragm 2 and coupled to a voice coil bobbin 6. The coupling member 8 includes an annular outer peripheral connecting part 21 connected to an outer peripheral portion of the diaphragm, an annular voice coil connecting part 22 which is coupled to a central portion of the outer peripheral connecting part 21 and to which a distal end side outer peripheral portion of the voice coil bobbin 6 is fitted, and a center axis connecting part 23 which lays the outer peripheral connecting part 21 along a centerline of the outer peripheral connecting part 21. |
