Abstract

PURPOSE:To exhibit excellent stereo effect, by supplying stereo signal through the provision of small sized speakers at the left and right of car space in the front and large sized speakers at the left and right of back side via an LPF having almost 150 Hz cutoff frequency. CONSTITUTION:Left and right outputs of a stereo audio equipment 11 consisting of a stereo turner and a stereo tape deck are balanced 12, and the outputs are amplified 13 and 14 respectively to drive small sized speakers 4 and 5. The left and right outputs of the balance adjusters 12 are amplified 17 and 18 via LPFs 15 and 16 having about 150Hz cutoff frequency to drive large sized speakers 8 and 9. The speakers 4 and 5 keep medium and high tone and the speakers 8 and 9 at the back side produce sufficient low tone by taking a trunk as a resonance box. Thus, excellent stereo sound field can be obtained in a narrow car space.
