Patent ID: 8103044

Claim:
A speaker device comprising a first diaphragm in which an outer peripheral edge is connected to a frame through a first edge portion and in which an inner peripheral edge is connected to a voice coil bobbin, wherein the inner peripheral edge of the first diaphragm is accommodated in an adhesive receiver disposed in an outer peripheral surface of the voice coil bobbin, the first diaphragm, the adhesive receiver and the voice coil bobbin are connected to each other by an adhesive filled into the adhesive receiver, the adhesive receiver is formed by an annular bottom surface and a peripheral wall which cylindrically rises from a peripheral edge of the bottom surface, an adhesive reservoir having a U-shaped cross section is formed between the adhesive receiver and the outer peripheral surface of the voice coil bobbin in a state where the adhesive receiver is disposed on the outer peripheral surface of the voice coil bobbin, a step rising from the bottom surface toward an acoustic radiation is formed on the adhesive receiver in the adhesive reservoir, and the adhesive reservoir is embedded by the adhesive in a state where the inner peripheral edge of the first diaphragm abuts against an upper surface of the step.
