装置。 A sound source such as a tuner or tape recorder, a preamplifier that amplifies the voltage of the musical sound signal generated by the sound source, a main amplifier that amplifies the output of the preamplifier with power, and is driven by the output of the main amplifier and emits musical sounds into the car. In an in-vehicle audio device consisting of a speaker that produces sound, the sound source, preamplifier, power amplifier, speaker, etc. are shared by at least two types of vehicles, and one of the sound sources, preamplifier, power amplifier, speaker, etc. is used in one type of vehicle. At least a dedicated equalizer for one type of vehicle is provided that optimizes the frequency characteristics mainly in the mid-range when the speaker is installed at a predetermined reference position, and a dedicated equalizer is provided for the other type of vehicle in the same way. Among the frequency characteristics of the sound source, preamplifier, power amplifier, speaker, etc., at least when the speaker is installed at a predetermined reference position, a dedicated equalizer for the other type of vehicle is provided that optimizes the characteristics mainly in the mid-range. The dedicated equalizer is provided so that the frequency characteristics of the dedicated equalizer cannot be substantially changed by general users, and by selectively installing the dedicated equalizer for each vehicle type, a predetermined frequency characteristic compensated for each vehicle type can be obtained. An in-vehicle audio device characterized by:
