Abstract

PURPOSE:To improve frequency characteristics and reduce the distortion for a speaker, by producing a sum signal of a signal delivered from the 1st operational amplifier and an input original signal through the 2nd operational amplifier and driving the speaker based on the output of the sum signal. CONSTITUTION:A detection signal S1 is supplied to an amplifier 3 and amplified so that a signal level becomes equal to the same value as an input original signal Sin at a frequency band higher than the low band resonance frequency of a speaker 1. Both output S2 of the amplifier 3 and the signal Sin are supplied to an operational amplifier 4, and a signal based on a difference of both inputs is delivered from the amplifier 4. This difference signal plus the signal Sin are supplied to an operation amplifier 5, and a signal based on a sum of both inputs is delivered from an amplifier 6. The output of amplifier 5 is amplified again by the amplifier 6 and then applied to the speaker 1.
