PROBLEM TO BE SOLVED: To solve the problems that both support springs are not easily parallelized and a performance is not improved when a case is formed by joining two frames for which the two support springs are respectively insert-molded in a multifunctional converter for suspending a magnetic circuit part on both surfaces by the two support springs and generating sound or vibrations by electric signals. SOLUTION: The case is constituted of one frame 13, and the magnetic circuit part composed of a pole piece 3, a magnet 4, a top plate 5 and a weight 6, etc., is suspended on both surfaces by the two support springs A and B (7, 14). The support spring A is insert-molded in the frame, the support spring B is not inserted, a support spring outer shape is fitted to a short cylinder part provided on the end part outer periphery of the frame, and it is pressed by a fixing ring 15 and joined with an adhesive material. The short cylinder part is provided with a notch 13b, the projected part (similar to 15a) of the support spring is fitted to the notch, and the direction of the arm of the support spring is determined. Thus, a high-performance multifunctional converter capable of parallelizing both support springs and determining the direction of the support springs is obtained. COPYRIGHT: (C)2006,JPO&NCIPI
