IPC: H04R3/00
Filed: 1987-12-07
Abstract: PURPOSE:To prevent the occurrence of differences in acoustic pressure and phase at a point even if the distances from a right and left loudspeakers to the point are different from each other, by providing a remote control means which independently rotates tweeter sections of a right and left loudspeaker boxes and, at the same time, independently changes the acoustic pressures and phases of the tweeter sections. CONSTITUTION:When a user depresses the button of a remote control section at a remote place while he listens to sound of a tape recorder with a radio receiver or component stereo, the signal is received by a photodetecting section Z1 and the signal is transmitted to the terminal 11 of a remote control IC5 from the terminal 1 of the section Z1. When the signal is received, the voltage across the terminal 12 of the IC5 changes from OV to +5V and the +5V is applied across the terminal 5 of a motor normally/reversely driving IC4. When the +5V is applied to the terminal 5, the supply voltage VB of the IC4 is applied to the terminal 1. When the supply voltage is applied to the terminal 1, the supply voltage is applied to the normal-rotation terminal of a motor 7 and the motor 7 is driven in the normal direction. As a result, the tweeter section of a loudspeaker box is turned rightward.
