Abstract

PURPOSE:To obtain a preferred sound volume level by storing a sound level signal to a memory in a form of digitized information and using an operation section to select the stored content. CONSTITUTION:When a preset section 7 executes [sound volume up] or [sound volume down] operation to obtain a preferred sound volume level, a microcomputer 8 increases or decreases a counter 3 and the digitized information of the counter at this time is stored in a memory 1C. The operation section 9 has key matrix circuits of number of pieces of information stored therein, and the microcomputer 8 reads the stored content by selecting optionally the desired storage sound level signal and reading it, and the result is outputted to a D/A converter 4. Circuits after the D/A converter 4 and succeeding are the same as conventional examples.

Therefore, as shown in FIG. 1, the circuit uses signals from the operating section 1 for "volume amplifier" and "volume down" to turn the volume counter 3 "up" or "up" or "down" by the microcomputer 2.
'down'. Then, in the 84th step, D/Mucomparta 4
This output is taken out as a DC voltage through the integrating circuit 5 and added to the volume control voltage of the audio output circuit 6. For this reason, in order to obtain the desired volume level, you must use "volume up" or "volume down" operations continuously, and depending on the operation method when searching for the desired volume level, you may have to It was easy to put away and the operability was poor.
