摘要： A speaker diaphragm assembly comprises a body made of a foam resin, and a sound radiating surface portion integrally formed with the body. In one embodiment, the sound radiating surface portion is made of a foam resin the density of which is greater than that at the body. In another embodiment, the sound radiating surface portion comprises a thin layer made of a solid resin, which thin layer is welded to the body. The rear end portion of the body may be reinforced in the same manner. In another embodiment, a supporting member is attached to the side surface of the diaphragm body for increasing the efficiency in vibration transmission from the voice coil. In another embodiment, a ring-like recess is made in the side surface of the body for spaced electrical terminals, to which heat is transmitted from the voice coil via lead wires, from the body, while a sub cone having low thermal conductivity is sandwiched between the lead wires and the body.

摘要： 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.
