Abstract

PURPOSE:To obtain excellent presence, by supplying stereo signals, through the provision of small sized speakers at the left and right of a car front space, small sized speakers at the left and right of the middle of the space via a delay circuit, and large sized speakers at the back via an LPF. CONSTITUTION:The left and right outputs of a stereo audio equipment 13 consisting of stereo turner and stereo tape deck are balanced 14, a part of left and right signals for the front's share are respectively amplified 15 and 16 to drive front small sized speakers 4 and 5, the rest front left and right signals are delayed 17, 18 and amplified 19, 20, to drive small sized speakers 6 and 7 at the middle. The left and right signals of the balance adjuster 14 are amplified 23 and 24 via LPFs 21 and 22 having almost 150Hz cutoff frequency to drive large sized speakers 10 and 11. Thus, localization is given with the speakers 4 and 5 for the left and right, the feeling of reverberation is given with the speakers 6 and 7, low tone is provided with the speakers 10 and 11, allowing to form excellent presence in a narrow car space.
