Abstract
The present invention provides a sound outputting apparatus, including: a housing; an electro-acoustic conversion section provided in the housing and configured to acoustically reproduce and output a sound signal; an acousto-electric conversion section provided at a position of the housing at which sound acoustically reproduced by the electro-acoustic conversion section can be collected; a removing section configured to remove a component of the sound signal from an output signal to be outputted from the acousto-electric conversion section based on an acoustic transfer function between the electro-acoustic conversion section and the acousto-electric conversion section; a decision section configured to decide whether or not a predetermined operation is performed for the housing based on an output signal from the removing section; and a control section configured to control so that a predetermined process is performed based on a result of the decision by the decision section.
