Abstract

PURPOSE: To obtain stable reproducing characteristic by converting a detection output of a detection means detecting the quantity and direction of a movement of a head of a listner into a control data and giving the control data to a change circuit of transfer function and a variable delay circuit so as to vary the transfer function and the delay time.
CONSTITUTION: A direction signal Sd changing 0 or 1 depending on the head of the listner turned clockwise and counter clockwise is extracted from a detection circuit 72. Pulses Pa of a number proportional to a varied angle when the listner changes the direction of the head are extracted from a detection circuit 73. Then the signal Sd is supplied to a memory 77 as an address signal to read a control data from the address corresponding to the table in the memory 77. Thus, since audio signals L, R fed to a headphone 6 become a main audio signal and a crosstalk component having a transfer function and a delay time depending on the direction of the head of the listner, the stereo sound field presence equivalent to the stereo reproduction by speakers is obtained.
