Reference numeral 3 denotes a controller including a CPU which sends a tone color switching signal in response to an ON signal of the switch 2. Reference numeral 4 denotes a sound generator for generating a music box performance music stored in advance. An audio amplifier 5 amplifies the output signal of the sound generator 4. Reference numeral 6 is a speaker, and 7 is a volume with a power switch. The volume is varied along with the power on / off control.
[0003]
As a control signal from the controller 3 to the sound generator 4, data / command (D / C) for timbre designation is sent as shown in FIG. 9 by pressing the pushbutton switch 2, and subsequently, the data No. constitutes the controller 3. The timbre is sent from the 8-bit CPU. Data (D0 to D7) and data / command (D / C) are read at the falling edge of the enable signal (E).
