ABSTRACT:
An optoelectronic pickup that generates a fluctuating voltage that is analogous to the vibrations of a vibrating body. When utilized with the vibrating body of a musical instrument and amplified and fed to a speaker the musical tones are reproduced at an amplified level. When the signal is fed to an FM transmitter the musical tones can be reproduced in any FM radio receiver. The device makes possible portable electric instruments and ‘wireless’-electrical instruments, i.e. a guitar that does not require a connecting cord or amplifier. The device anticipates new and unique musical instruments.
