Abstract
An audio signal supplying device includes a connection terminal which is connected to a speaker unit and which outputs an audio signal to the speaker unit, a specifying section which specifies a type of the speaker unit connected to the connection terminal, an acquiring section which acquires a parameter corresponding to the type of the speaker unit specified by the specifying section from an outside, a storing section which stores the parameter acquired by the acquiring section, an inputting section into which the audio signal is input, an acoustic characteristic controlling section which adjusts an acoustic characteristic of the audio signal input into the inputting section based on the parameter stored in the storing section, and a supplying section which supplies the audio signal whose acoustic characteristic is adjusted by the acoustic characteristic controlling section to the connection terminal.
