Therefore, the combination of many parts used in the vibration part is singulated by insert injection to minimize the characteristic dispersion of the vibration part and to the center of the permanent magnet. It is a technology designed to realize mass production that can maintain a certain distance between field coils and permanent magnets and to maintain certain characteristics when fixing a shaft and using JIG at the center of each case.

In order to achieve the above object, it is possible to standardize the assembly work by separately inserting the flange part of the leaf spring, which can be changed according to the metal joining method, through injection molding.

2. 샤프트에 영구자석을 JIG를 사용하여 일정한 위치에 고정시킨 다음, 그 샤프트를 하case에 고정하여 진동부의 상.하 반복운동시 일정한 진폭을 유지할수 있도록 한다.2. Fix the permanent magnet on the shaft at a certain position using JIG, and then fix the shaft to the lower case so that it can maintain a constant amplitude during the up and down repeated movement of the vibration part.

3. 진동부를 구성하는 부품중 브라켓에 환형계자코일, 진동자를 접착하고 그 바닥면에 인쇄회로기판을 접착한후 1차 인써트사출된 판스프링과 함께 2차 인써트사출금형을 사용하여 진동부의 각부품 체결부위와 판스프링 고정부위를 사출폼화하여 단품화한다.3. Attach the annular field coil and the vibrator to the bracket among the components constituting the vibrating part, and attach the printed circuit board to the bottom surface of each part of the vibrating part using the secondary insert injection mold together with the plate insert with the first insert. The fastening part and the plate spring fixing part are molded separately by injection foaming.
