Abstract
An electronic system having a chime and strike program simulating the program of a Westminster clock including an actuating source, a solid state integrated circuit and a loud speaker. The integrated circuit includes a plurality of counters for activating a frequency synthesizer and both tone switching and generating circuits thereby to generate the strike and chime program on the hour and a chime program on the other quarter hours indicative of the time throughout a 24-hour period. The chime program is sequenced by a chime matrix.
Claims17
An electronic strike and chime generating system and the like comprising in combination:
- a. means commanding a chime program comprising a plurality of notes in ordered sequence;
- b. means activating said chime program commanding means upon at least each hour interval;
- c. means commanding a strike program, said strike program commanding means activated upon each said hour interval after completion of said chime program;
- d. frequency synthesizer means;
- e. means electrically connecting said frequency synthesizer both to said strike and chime program commanding means for response to the same thereby providing a plurality of outputs each comprising a multiple of the frequency of the fundamental tone of at least some of said notes of said programs;
- f. means for generating the fundamental frequency with selected harmonics of all notes of said programs;
- g. a loud speaker responsive to said generating means for sounding said programs;
- and
- h. means electrically connecting said loud speaker and said generating means.
