Abstract
An information processing apparatus includes: two amplifiers that and output sound signals based on sound data to two speakers, respectively, that the stereo speaker has; a connector that connects the amplifiers to the two speakers; and a microphone. When a first stereo speaker is to be connected to the connector, the stereo speaker is connected so that the two speakers of the first stereo speaker are in phase with each other. When a second stereo speaker is to be connected to the connector, the stereo speaker is connected so that the two speakers of the second stereo speaker are in reverse phase with each other. The information processing apparatus outputs a sound signal based on predetermined sound data from the amplifiers to the stereo speaker, thus identifying the type of the stereo speaker connected to the connector based on the sound collected with the microphone.
