Abstract
A vibrator motor has a stationary piece and a moving piece hinged at one end. The moving piece does not generate substantial internal spring forces under the influence of an electromagnetic field, because it does not have a tail bracket. Other parts of conventional motors are also eliminated, so the motor is easier and less expensive to manufacture. In addition, the motor can be assembled and tuned before installation, which increases the ability to automate assembly.
