ULTRA-LOW FREQUENCY SOUND INTENSIFYING DEVICE UTILIZING VIBRATING MOTOR

摘要

PROBLEM TO BE SOLVED: To intensify an ultra low frequency sound of a device using an electroacoustic transducer to transduce an audio electric signal into a sound output. SOLUTION: The device includes a vibrating motor, a vibration transmission means that is worn on a body of a listener and delivers the vibration produced from the vibrating motor to the listener, and a motor control means for extracting a low frequency component of an audio electric signal to provide an output of a control signal of the vibrating motor. The motor control means detects a low frequency component of the audio electric signal to drive the vibrating motor and deliver the vibration to the body of the listener thereby allowing the listener to sense an ultra low frequency sound by its body.
