Abstract
PURPOSE:To attain the compensation of a sound field which is faithful to the stereophonic logic, by using a transmission function compensating circuit consisting of a frequency characteristic compensating equalizer and an electric signal delaying circuit, and an electric signal inverting circuit, etc. CONSTITUTION:With a transmission function compensating circuit, etc., the input signal to be supplied to an input terminal IR of a speaker 2 which is set front to the external auditory meatuses 3 and 4 of a listener is supplied to the 1st transmission function compensating circuit 31 consisting of a frequency characteristic compensating equalizer 41 and an electric signal delaying circuit 42 for example. Then the output of the circuit 31 is supplied to the 2nd transmission function compensating circuit 32 consisting of a frequency characteristic compensating equalizer 43 and an electric signal delaying circuit 44. The outputs of both circuits 31 and 32 are added together by an adder circuit 45 to be supplied to a speaker 2. Then the input signal to be applied to an input terminal IL of the speaker 1 excepting the front speaker and the signal obtained by inverting the input signal to the terminal IR through an electric signal inverting circuit 46 are added together by an adder circuit 47 to be supplied to the speaker 1.
