Abstract

PURPOSE:To orientate the actual acoustic image in the space, by converting two frequencies (1,500Hz and 3,000Hz) at least of the accoustic wave to frequencies with phases shifted by 90 deg. or adding these frequencies. CONSTITUTION:Frequency signals of, for example, 1,500Hz and 3,000Hz are caused to pass through band-pass filter 40 and are shifted in phase shifting circuit 41 by 90 deg.. Simultaneously, the original frequency signal with frequency components of 1,500Hz and 3,000Hz eliminated is formed by filter 42, and the synthesizing circuit which synthesizes outputs of phase shifting circuit 41 is used to orientate the acoustic image forward.
