Title: Vehicle acoustic equipment controller
Inventor: HIRATA EIJI
IPC: H03G5/16
Filed: 1986-10-29
Abstract: PURPOSE:To remove the trouble of an adjusting operation and to improve the safety of driving by making an equalizer act automatically so that the output signal from a selected audio source comes to be a frequency characteristic for the audio source. CONSTITUTION:A change-over switch 7 selects an optional signal from plural signal sources. The equalizer 9 gives the prescribed frequency characteristic to the signal outputted from a sound volume 8 to adjust the largeness of the selected signal. The output signal from the equalizer 9 and a bit of selected source information from the switch 7 are inputted to a control unit 10. When the frequency characteristic and the sound volume of this output signal do not correspond to the audio source decided from the selected source information, the unit 10 reads out a frequency characteristic pattern signal and a sound volume changing signal corresponding to the audio source from a memory 11 and transmits them to actuators 12, 13. Accordingly, a driver need not adjust the equalizer at every switching of the switch 7.
