Electronic musical box
First Claim
1. An electronic musical box comprising:
- pulse generator means for generating a unitary pulse for a note whose duration is the shortest in a given musical score and generating integer numbers of unitary pulses for the other notes therein;
tone pitch signal generating means for generating coded tone pitch signals coded by a plurality of tone pitch switches so as to correspond to the tone pitches of the notes in said musical score;
memory means having a plurality of addresses and responsive to said pulse generator means for storing each of said coded tone pitch signals in a number of successive addresses of said memory, said number being equal to the number of unitary pulses generated by said pulse generator means; and
musical tone generating means for reading data stored in said memory means thereby obtaining musical tones from the outputs of said memory means at a desired time.

Abstract
An electronic musical box is disclosed in which a musical score can be readily stored and reproduced and the musical score can be easily changed to another. The musical box includes a pulse generator for generating a unitary pulse for a note whose duration is the shortest in the musical score and generating integer numbers of unitary pulses for other notes in the musical score. A tone pitch generating circuit generates tone pitch signals coded by a plurality of tone pitch switches so as to correspond to the tone pitches of the notes in the musical score. The coded tone pitch signals are stored in a memory, and a musical tone generating circuit reads data stored in the memory and generates musical tones.
