ABSTRACT:
The diaphragm of a speaker is supported by a viscous supporting member placed in an annular gap defined between the periphery of the diaphragm and the inner surface of a frame structure and by a conventional damper. Grooves may be made in the periphery of the diaphragm and in the inner surface of the frame structure for receiving some portions of the viscous supporting member. In another embodiment, a film made of a resin is welded to the front surface of a diaphragm body which is made of a foam resin. In other embodiments, one or more reinforcing members are fixedly adhered to both the voice coil bobbin and the flat rear surface of the diaphragm.
