Patent ID: 7917239

Claim:
An information processing apparatus comprising: a body; an amplifier provided in the body, and amplifying a sound signal to output sound from a speaker; a first system provided in the body, the first system including a storage storing a first sound data and a sound device which generates an analog sound signal from the first sound data and supplies the generated sound signal to the amplifier, and configured to operate under the control of an operating system, and further, outputting sound using the first sound data when the body is in a power-on state; and a second system provided in the body, the second system configured to operate independently from the first system, and including a semiconductor memory storing a non-compression format second sound data and a digital-to-analog converter, which converts the second sound data into an analog sound signal and supplies the converted analog sound signal into the amplifier, and further, outputting sound using the second sound data when the body is in a power-off state, wherein the amplifier has a function of amplifying an input sound signal with a predetermined amplification factor, and supplying the amplified sound signal to the speaker, wherein the semiconductor memory stores one or more digital sound data having the same sound output from the speaker as the second sound data but different volumes than the second sound data; and wherein the second system further comprises: a second semiconductor memory that stores volume information; a selecting section which selects one of the one or more digital sound data having different volumes in accordance with the volume information; and a transferring section which transfers the selected sound data to the digital-to-analog converter.
