Abstract
A musical tone generating apparatus employs an array of microresonant structures to generate the harmonic component signals of a musical tone to be generated. The microresonant structures produce high frequency signals which are down converted to audio frequency range by mixing them with a high frequency reference signal. The desired tone color is achieved by modifying the relative amplitudes of the harmonic component signals to produce a desired tone color. A large number of microresonators are preferably integrated on a single integrated circuit substrate to provide a variable tone generating system in a relatively compact environment.
