PURPOSE:To eliminate a limit to the action range of a listener and to remove a failure that a cord is caught, an earphone is taken off and listening can not be performed by attaching a receiver and the earphone or a speaker, etc., capable of listening to sound from the receiver to the remote control box of an audio equipment provided with a sound oscillator function and thereby listening to the sound through the earphone without the cord. CONSTITUTION:Inside the remote control box 2, the receiver for receiving the sound of a television 1 is arranged and an earphone jack 3 for outputting the sound from the receiver is provided. Then, when the power source of the remote control box 2 is turned ON and an earphone plug 4 is mounted to the earphone jack 3 of the remote control box 2, the sound of the speaker of the television 1 is silenced by remote control and the sound of the television 1 can be listened to only by the listener himself/herself through the earphone 5. Also, a small-sized speaker may be built in the remote controller instead of the earphone 5. |
