PROBLEM TO BE SOLVED: To provide a speaker set in which output from a center speaker can be altered quickly and easily. SOLUTION: The speaker set comprises a separation circuit 30 and a comparison circuit 32 constituting a proximity detecting means, and a switching circuit 34. Output mode of a center speaker 20 is converted based on a detection signal from the comparison circuit 32. Since the output of the center speaker 20 is switched by simply altering the distance of an L channel speaker 12 and an R channel speaker 16, conventional operation of a switching means is not required for the user and the output of the center speaker 20 can be switched quickly and easily. |
