Abstract
Provided is a speaker device including a cabinet whose direction is changed in accordance with an installation state, and capable of detecting the direction of the device based on received optical signals. The speaker device can be installed in a state in which the speaker device is placed on a rack such that a receiving unit faces a listening position, and a state in which the speaker device is hung on a wall such that a receiving unit faces the listening position. Voltage converting units are configured to convert photocurrents output by light receiving elements according to received light amounts of an infrared ray from an infrared remote controller to voltage signals to output the signals to a controller. The controller compares amplitudes of the voltage signals to each other, thereby detecting a state (direction) of the speaker device.
