IPC: H04R3/04
Filed: 1989-04-21
Abstract: PURPOSE:To prevent generation of nonlinear distortion even at a large output by constituting a device such that a level of a signal of a frequency band is adjusted only when the signal of the frequency band causing nonlinear distortion of a speaker reaches a level causing the nonlinear distortion or over. CONSTITUTION:A measurement changeover switch 18 switches an output of a speaker nonlinear distortion characteristic measuring circuit 13 to the position of a power amplifier 20, outputs a reference signal to measure the nonlinear distortion characteristic of the speaker 21. Then the switch 18 is turned to the position of a subtractor 10. Filter circuits 3, 4 users the information from the measuring circuit 13 to pass only the signal in the nonlinear distortion region and a level detector 7 detects its level and the result is inputted to an input distortion level discrimination circuit 8. The discrimination circuit 8 compares a signal from the level detector 7 with a preset value and inputs the result to a level adjustment device control circuit 9. The control circuit 9 outputs a control signal is response to the signal from the discrimination circuit 8 to a level adjustment device 6 to adjust the attenuation. Then a signal subjected to band limit by the filter circuit is subjected to level adjustment and a subtractor subtracts the result from the input signal.
