    Abstract: Disclosed herein is an acoustic diaphragm for converting electrical signals into mechanical signals to produce sounds. The acoustic diaphragm comprises carbon nanotubes or graphite nanofibers as major materials. Preferably, the carbon nanotubes or graphite nanofibers are included or dispersed in the acoustic diaphragm. Since the acoustic diaphragm has excellent physical properties in terms of elastic modulus, internal loss and strength, it can effectively achieve superior sound quality and high output in a particular frequency band as well as in a broad frequency band.

    Abstract: Water-proofed natural pulp or organic synthetic fibers are with polyester-type fibers having a low melting point, and subjected to a paper fabrication process. The fabricated product is dried with hot air at a temperature higher than the melting point of the polyester-type fibers, thereby melt-bonding only intersections of the fibers without completely fusing the polyester-type fibers. The pressure of the hot air contributes to the formation of a predetermined shape. Thus, a water-proof diaphragm for a loudspeaker, having a large thickness, a low density, a high internal loss and a high stiffness, is obtained. By incorporating the thus formed diaphragm, a high-performance loudspeaker having a low distortion and a broad reproducing range is obtained.

    Abstract: A diamond vibration plate of a speaker which has high sound velocity or E/ρ would be superior in high-pitched tone performance. However, diamond vibration plates which are made overall from crystalline diamond were apt to split or break at a flange due to the high rigidity. The periphery of the flange is circularly cut by laser beams to eliminate rugged circumference. The laser treatment converts the crystalline diamond of the flange into non-diamond carbon. The vibration plate with a central spherical part of crystalline diamond and a periphery of a flange of non-diamond carbon excels both in high frequency property and mechanical strength.
