GREETING CARD WITH MUSICAL PERFORMANCE AND ELECTRONIC DEVICE FOR REGENERATING MUSICAL SOUND USED FOR SAID CARD

摘要

A musical tune generator has a read only memory (34) which stores information corresponding to the notes of a preselected musical tune. An oscillator (22) drives an address circuit (26) which sequentially accesses the memory locations in the read only memory (34). A progammable frequency divider (24) is also coupled to the oscillator output, and is controlled by a portion of the read only memory output (36). Output from the programmable frequency divider corresponds to notes of the preselected tune and are reproduced in an audible mode. In a preferred embodiment, the tune generator is encapsulated within a greeting card (40) and is controlled by a switch (16) which enables the preselected tune to be played when the greeting card is opened.
