PURPOSE:To enjoy television broadcasting without bothering neighbors by incorporating a speaker in a remote control and emitting the sound of a broadcast station received by a television receiver. CONSTITUTION:The output side of a low frequency amplifier circuit 10 is connected to a remote control with built-in speaker 15 by switching a speaker connection switching circuit 12. The power source connection/disconnection part 20 of the remote control 14 is operated, and a power source is applied by controlling a power source circuit by a channel selection controller 17. Thence, the receiving station switching part 18 of the remote control 14 is operated, and a receiving channel is switched to a desired one by controlling the tuning element of a tuner 1 by the channel selection controller 17. Moreover, the sound volume adjusting part 19 of the remote control 14 is operated, and a sound volume is set at a desired sound volume by controlling the sound volume control circuit 11 of the low frequency amplifier circuit 10 by the channel selection controller 17. In this way, the sound of a desired broadcast station received by the television receiver emitted from the remote control with built-in speaker 15 can be heard. |
