Abstract
PURPOSE:To rationalize the production of the titled vibrating member with the improvement of the characteristics, by unifying a cone part to radiate the sound and a bobbin part to mount a voice coil by means of a sheet of synthetic resin and forming the voice coil with the film making technique. CONSTITUTION:For a vibrating member 14 for speaker, an edge 14a, a bobbin part 14b and a cone part 14c are formed into a body by means of a sheet of synthetic resin such as an aromatic polyester polyarylate film, etc. A voice coil 19 is formed on the part 14b by the vapor deposition of the chemical plating, and then a film of a desired shape is formed by the etching process, the mask vapor deposite or the mask plating method. The terminal of the coil 19 is drawn out to a part of the part 14c and then connected electrically to an external input terminal 8b attached to a frame 8 via a lead wire. In such way, both the number of processes and the time of production can be reduced. And the speaker efficiency is increased owing to use of a light-weight voice coil.
