Abstract
Provided is a speaker device, which includes speaker units having different diameters and sound emission directions, and which is capable of suppressing variations in sound quality at a listening position, which are caused by changing an orientation in which the speaker device is installed. A speaker device has first and second speaker units, which have different diameters and sound emission directions, mounted thereto. A controller is configured to control, depending on the orientation in which the device is installed, an equalizer correction unit to correct frequency characteristics of acoustic signals input to the first and second speaker units so that sound quality is not varied at the listening position depending on the difference in diameter and sound emission direction.
