Abstract: A method for manufacturing a speaker diaphragm used for a range of audio equipment, a speaker diaphragm made using this manufacturing method, and a speaker employing such diaphragms. This manufacturing method for a speaker diaphragm offers good productivity, preventing deviation in wettability and heat deformation of speaker diaphragms in plasma treatment, and also offers a speaker with good input power durability. A meshed etching tunnel (2) made of aluminum is disposed inside a cylindrical quartz reactive chamber (1), and speaker diaphragms (4) are aligned inside the tunnel at a certain interval. Opposing electrodes (5) are disposed outside the reactive chamber (1). Plasma is applied at low temperature to prevent heat deformation. Uniform wettability is also assured by the use of the meshed etching tunnel (2), achieving high productivity.

Abstract: A speaker edge is made of a thermosetting composition consisting of a polyurethane prepolymer and an inactivated solid polyamine as a latent hardener. A gas is dispersed in the thermosetting composition, prior to feed into a mold, so that it can foam and solidify to give the speaker edge. In a method of making the speaker edge, the composition will be injected into a female mold segment heated below the critical thermosetting temperature, foaming the composition. Then placed in the female segment is a male segment heated above the critical temperature, causing the ingredients to react with each other to solidify in the mold.

Abstract: A diaphragm is gained by the co-molded of a dome part, a voice coil junction part, a cone part and a peripheral part through the injection mold of thermoplastic resin. The thickness of the central part of the dome is made great so that the resonance amplitude in this part becomes small. In addition, an annular rib is integrally provided to the voice coil junction part so as to increase the junction strength between the diaphragm and the voice coil bobbin. Thus, the electromagnetic driving force of the voice coil can be effectively transmitted to the diaphragm so that a loud speaker with excellent characteristics can be gained.
