Abstract

A multi-actuator selectively performing audio and vibration generating operations is made by injection molding process of inserting a spring into a case forming an exterior appearance of the multi-actuator. The spring is inserted into the case using an exterior structure integrally formed with the spring, and the exterior structure is cut off from the case after the injection process is finished. In the method of inserting the spring into the case, a plurality of guide holes are formed on the exterior structure and outside springs in a spring array state, and the springs are disposed and inserted into the injection-molding in the array state so that a productivity is improved. Since interference between the springs and the injection molding, deformation of the springs is prevented.
