Slimming of a smart-phone is one of the key technologies in the current smart-phone industry. Because the vibration actuator is the thickest part of a smart phone, a slim linear vibration actuator has been developed. For the analysis of the vibration characteristic of a smart-phone, experiment has been used one of the most popular techniques, but it consumes a lot of cost and time especially in manufacturing prototype for experiment. Accordingly, as an alternative to experiments, mathematical modeling and analysis can be applied because it is simple and accurate. In addition, computation iteration can be carried out for optimal design. In this paper, a mathematical modeling is created for analysis of the vibration characteristics of a smart-phone applied with a horizontally vibrating linear actuator. In addition, the result of the mathematical analysis is compared with that of the experiment for verification.
