ABSTRACT:
An audio-responsive massage system includes a pad for contacting a user of the system; a plurality of vibratory transducers, each transducer having an eccentric element for vibrating the pad at variable intensity and associated vibration frequency in response to a power signal; a microphone for response to a remotely located source to provide an audio signal; an audio filter for selecting a desired frequency characteristic of the audio signal; a detector circuit for producing a control signal as an amplitude envelope of the audio signal and including a detector diode connected for feeding a low-pass filter; a power amplifier for producing the power signal in response to a control signal; and a sequencer for periodically activating different ones of the transducers for drive by the power amplifier. Also disclosed is a method for massaging a user in response to an audio source including the steps of providing a massaging pad having a vibratory transducer coupled thereto, and a coupler connected to the transducer for variably powering the transducer; contacting the user with the pad; operating an envelope detector in response to the audio source for producing a control signal; and feeding the control signal to the coupler for activating the transducer, thereby massaging the user with variable intensity in response to the amplitude envelope of the audio source.
