Abstract

PURPOSE:To produce a sound having a flat frequency property at all times for a tone correcting device of the automobile acoustic device, by interlocking the control of sound volume balance with the correction of sound for two speakers. CONSTITUTION:The signal received through the antenna 3 and the tuner 4 or the signal sent from the tape deck 5 is sent to the speakers 1 and 2 which are installed with an appropriate space secured between them via the preamplifier 7, the sound quality control circuit 11 consisting of a low pass filter or high pass filter, the main amplifier 8 plus the sound volume balance control means 9 and 10 each. The means 9 and 10 are coupled to each other to secure an adjustment of the sound volume in the opposite way to each other. The control circuit 11 is operated in coupling to the means 9 and 10 to secure an automatic correction to a flat frequency property in accordance with operation of the means 9 and 10. In such way, a sound having a flat frequency property at all times can be obtained.
