Abstract

PURPOSE:To inform surely an emergency alarm broadcast to a recipient by controlling sound from being listened to from a speaker automatically even when an earphone plug or a headphone plug is plugged in and the emergency alarm broadcast is received. CONSTITUTION:When an alarm signal is inputted to a coincidence detection and external control section 4 from a broadcast reception section 1 and the signal is coincident, an extent control signal is fed to a sound signal amplifier section 2 and a switch circuit 3. When the external control signal is fed to the sound signal amplifier section 2, a receiver whose power is turned off is controlled to be activated and the level of a sound signal is set and the sound is outputted in a prescribed sound volume. Similarly, when a control signal is fed from the signal coincidence detection and external control section 4 is fed to the switch circuit 3, the switch circuit 3 is thrown to the 2nd switch position (b) from the normal 1st switch position (a). When the switch circuit 3 is thrown to the 2nd switch position (b), the sound signal inputted to a common terminal (c) of the switch circuit 3 connects directly to a speaker via the 2nd switch position (b).

BACKGROUND TECHNOLOGY In general, receiving devices such as radio receivers and television receivers use internal speakers to listen to the audio, and when listening through earphones, headphones, etc., it is possible to listen to the audio by inserting an earphone plug or headphone plug. The system is designed to cut off audio output from the internal speaker. The method for outputting audio from the internal speaker is the same for emergency warning broadcast receivers as it is for attaching and detaching plugs such as earphones and throat horns to and from jacks. In other words, a conventional emergency warning broadcast receiver consists of a broadcast receiving section, an external control section that outputs several emergency warning signals, an audio signal amplification section, an earphone jack, and a speaker, and the audio signals received by the broadcast receiving section are The amplification section and the signal are input to the external control section. Normally, when the receiver is powered on, the audio signal is connected to the switch circuit of the earphone jack via the audio signal amplification section. Here, if the earphone plug is not inserted, the switch circuit of the earphone jack is in a conductive state and connected to the speaker, and an audio signal is generated from the speaker, and if the earphone plug is inserted, the switch circuit of the earphone jack is in a conductive state and connected to the speaker. is cut off, the audio signal is input to the earphone, and there is no audio output from the speaker.

Next, the operation when an emergency warning broadcast is received will be explained. An alarm signal is inputted from the broadcast receiving section to the external control section 4, and when the signals match, an external control signal is applied to the audio signal amplification section 2 and the switch I child circuit 3VC. When an external control signal is applied to the audio signal amplification section 2, when the receiver is turned off and is not operating, it is controlled to operate, and the level of the audio signal is set so that audio is output at a constant volume. controlled so that Also, even when the receiver is powered on, the audio is controlled to be output at a constant volume. Similarly, when a control signal is applied to the switch circuit 3 from the external control unit 4, the switch position of the switch circuit 3 changes from the normal first switch position (body) to the second switch position (b). . When the switch circuit 3 is in the second switch position (b), the audio signal input to the common terminal (C) of the switch circuit 3 is directly connected to the speaker via the second switch position (b). As shown in the diagram, you can hear audio output from the speaker even if the earphone plug is inserted.
