Abstract

PURPOSE: To reduce the distortion caused at the speaker cord, by connecting an amplifier between the adverse-phase output of an amplifier and a speaker to negate the voltage produced at an adverse-phase line.
CONSTITUTION: The signal supplied to the input terminal IN is amplified by the amplifier 14a to be delivered. The voltage produced by the impedance component and through the connection cord l5 that functions as the adverse-phase line of the speaker 22a is transmitted through the connection cord l4 to be supplied to the nonreverse amplifier 32. Receiving a supply of the detection signal from the amplifier 32, the reverse amplifier 33 produces an inverted output. This output signal is supplied to one input terminal of the amplifier 32 via the resistance R2 as well as to the negative pole input terminal 24B of the speaker 22a. As a result, a state equivalent to that under which the speaker cord is set at "0" is obtained. This equals the fact that the amplifier 14a is connected directly to the speaker 22a.
