Patent ID: 8724843

Claim:
An electrodynamic sound-emitting device including an outer yoke shaped having a bottom and a side wall, a magnetic circuit having a magnet and an inner yoke disposed surrounded by the outer yoke, a coil disposed in a magnetic gap configured in the magnetic circuit, a diaphragm to which the coil is fixed, and a first elastic member for elastically joining the diaphragm to the side wall of the outer yoke, the electrodynamic sound-emitting device comprising: a casing for covering the outer yoke, so as to form a cavity by this casing, the diaphragm and an outer surface of the side wall of the outer yoke; and a second elastic member for joining an inner circumferential edge of the casing to an outer circumferential edge of the diaphragm without any gap therebetween; wherein this second elastic member is provided with pores by foaming and made of a material whose elastic modulus is lower than that of the first elastic member, but is not provided with the pores communicating through from a back surface of the second elastic member, that is an inner side of the casing, to a front surface that is the opposite side of this back surface, wherein the second elastic member is annular, a flange is provided along the circumferential edge of the diaphragm, extending in an axial direction of the magnetic circuit, and an outer circumferential surface of the flange and an annular inner circumferential surface of the second elastic member are joined to each other.
