−たトーンコントロール回路。A first capacitor, a single-axis single-unit first variable resistor, and a second capacitor are connected in series between a terminal to which an audio signal is supplied and ground, and a third capacitor and a third capacitor are connected in series. , a resistor and a second variable resistor for volume residual adjustment are connected in series, and a movable element of the first variable resistor is connected to a connection point between the resistor and the second variable resistor. and the above first
a capacitor, a first variable resistor, a second capacitor,
゛The values of the third capacitor, the resistor, and the second variable resistor are selected, and the movable element of the first variable resistor is connected to the second variable resistor.
When the movable element of the second variable resistor is located on the side of the capacitor, the audio signal with attenuated low and high frequencies is extracted from the movable element of the second variable resistor, and the movable element of the first variable resistor is located on the side of the capacitor. When located on the side, the movable element of the second variable resistor outputs the audio signal whose frequency characteristics are higher than the audio signal whose low and high frequencies are attenuated, or whose frequency characteristics are substantially flat. let it be taken out
