Abstract :
In this paper, we proposed a coin shaped linear vibrator having a conical spring. The design of linear vibrator is simple rather than rotary vibrator, which leads to lower cost, easy manufacturing and long lifetime. To increase the vibration force of linear vibrator, we used conical spring. This paper details design procedure of the conical spring linear vibrator (CSLV) using electromagnetic field simulation, structural FE simulation and transient vibration analysis.
