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.

Information processing apparatus and control method

An information processing apparatus includes a processor which executes an OS; a speaker which outputs a sound; a short-distance wireless communication unit which outputs first information indicating that a specific signal is received by short-distance wireless communication; an EC which outputs first sound data to output a sound in response to acquiring the first information output from the short-distance wireless communication unit; and an audio processing device which exclusively switches between the sound based on the first sound data output from the EC and a sound based on second sound data output from the processor by processing based on the OS in order to output either one of the sounds from the speaker. When acquiring the first information output from the short-distance wireless communication unit, the EC causes the audio processing device to output the sound based on the first sound data from the speaker.

Provided are a touch pen and a touch pen system with a compact and low-cost configuration when an erase function is installed therein. The touch pen system includes a capacitive touch panel; a touch pen having a pen tip for specifying an arbitrary position on the touch panel and a pen rear end portion formed with a predetermined conductive pattern; predetermined pattern detection mechanism that detects contact of the predetermined conductive pattern with the touch panel; and an erase implementation mechanism that implements an erase function when the predetermined conductive pattern is detected.
