Abstract

Provided is a sound reproduction device including: speakers; light emitting elements provided to a part of each of the speakers, or in a vicinity of each of the speakers; a detecting section configured to detect a beat of an audio signal reproduced by the speakers, and output a detection signal corresponding to the beat; and a light emission control signal outputting section configured to output a light emission control signal for controlling a light emission mode of the light emitting elements according to the detection signal. The light emission control signal outputting section outputs a first light emission control signal according to the detection signal, and outputs a second light emission control signal when a period in which the beat is not detected exceeds a set period, the second light emission control signal being for controlling the light emitting elements to perform a predetermined light emission mode.
