Abstract
Little electric power, thin cellular phones are gaining remarkable popularity. Most recent cellular phones have a vibration function generated by a rotary vibration motor to notify the user of arrival of a message. We developed a little electric power, thin Linear Oscillatory Actuator (LOA). Its vibration acceleration is larger than that of rotary vibration motors. This paper describes: (1) the structure and operating principle of the LOA for cellular phones, (2) effect of a center yoke for increasing thrust force of the LOA, (3) influence of a center yoke on the LOA electric power for cellular phones, and (4) comparison between the LOA and rotary vibration motor.
