Claim Text:
1. An audio reproduction apparatus comprising: first and second speakers for left and right channels with speaker units, the first and second speakers each being configured as a bare speaker in which the speaker unit is not housed in a speaker box and is not attached to a baffle plate, to enable mixing sounds emitted from front and rear of vibration plates of the first and second speakers; first and second microphones provided in areas where the sounds emitted from the front and rear of the vibration plates of the respective first and second speakers are mixed and cancelled; a low-pass filter configured to supply noise reduction audio signals obtained by phase-inverting audio signals collected by the first and second microphones to the first and second speakers; and circuitry configured to supply predetermined audio signals to the first and second speakers, respectively, wherein the noise reduction audio signals are obtained by performing correction based on a spaced transfer function between a first position of a source of a noise sound and a second position where the noise sound is to be reduced.
