Description

  The present invention relates to an emergency broadcast receiving loudspeaker, and more particularly to a self-supporting emergency broadcast receiving loudspeaker that can be installed outdoors and perform its function without human work.

The Japan Meteorological Agency uses the nationwide instantaneous warning system (commonly known as J-ALERT) to broadcast emergency warnings on TV. When this emergency alert is transmitted, the information is distributed to residents outside by operating disaster prevention radio etc.
As a result, there are so many earthquakes that Japan is said to have entered the period of seismic activity, and the importance of emergency warning broadcasts against earthquakes and tsunamis has become higher than before.
However, in order to further increase the certainty of transmission, the above-described transmission method remains uneasy.
For example, even if an emergency warning for a tsunami after an earthquake occurs is transmitted by administrative radio or the like, the person in charge has already suffered from the earthquake and cannot respond.
In addition, the range in which the voice can be delivered by the disaster prevention radio is the range centering on the source where the person in charge is located, and it is not possible to cover places where people do not normally enter.

[Emergency warning broadcast]
When receiving the FM broadcast radio wave via the FM antenna 47 (FIG. 1), the receiving unit 55 outputs the sound information included therein to the audio signal switching control unit 57. The audio signal switching control unit 57 switches to an audio signal and outputs the audio signal at the maximum volume according to a control command from the control board 49.
Further, when the control board 49 receives an emergency warning signal start signal “Piropiro”, the control board 49 outputs an alarm issuing signal via the alarm issuing unit 59 and outputs the above sound output to the external loudspeaker amplifier (AMP) 33 (FIG. 3). Is turned on and amplified, and then the speaker 43 (FIG. 1) broadcasts loudly.
Therefore, when an emergency alert broadcast signal is received, the emergency alert is automatically broadcast with loud sound from the speaker 43.
In parallel, since the warning issuing unit 59 operates the red rotating lamp 41 (FIG. 1), it can be visually confirmed that an emergency warning is being broadcast.

[Other radio broadcasts]
A forced broadcast switch 25 (FIG. 3) is also provided. Even when the forced broadcast switch 25 is pushed up, the external loudspeaker amplifier (AMP) 33 is turned on and amplified, and then the loudspeaker 41 can be broadcasted.
Therefore, even if it is not an emergency warning broadcast, it is possible to broadcast loudspeaking by using the forced broadcast switch 25, and it can also be used for notification of an evacuation place or a disaster situation.

  The FM reception state display LED 17 (FIG. 2) blinks slowly during reception of FM radio waves, and blinks quickly during non-reception, so that the standby state can be confirmed.

The audio signal switching control unit 57 is provided with a recording device connection output terminal 37 and a playback device connection input terminal 38 (FIG. 3), and is connected to an IC recorder or the like to record broadcast contents. The recorded sound can be broadcasted through the speaker 43.
Therefore, necessary broadcast contents can be repeatedly broadcast later.

[Microphone broadcasting]
In addition, the audio signal switching control unit 57 is also provided with a hand microphone 35 (FIG. 3). By pressing the microphone broadcasting / FM broadcasting / external device broadcasting switching switch 27 (FIG. 3), the microphone side is opened. The utterance can be input. By operating the hand microphone 35, the loudspeaker 43 (FIG. 1) can be broadcasted in the same manner as when the broadcast radio wave is received by the external loudspeaker amplifier (AMP) 33 (FIG. 3).
Therefore, it can be used as a source of information unique to the user.

<Function confirmation unit: Fig. 5>
The function test switch 29 (FIG. 3) is used for the above-described function confirmation.
When the function test switch 29 is pressed, the control board 49 forcibly sounds the battery voltage drop alarm buzzer 53, turns on the red rotating lamp 41, and turns on the external loudspeaker amplifier 33.
Therefore, it can be confirmed whether the function is working normally auditorily and visually.

<Additional function part: Fig. 6>
The control board 49 is provided with a USB charging terminal 39 and can be used for charging a battery such as a mobile phone.
In addition, emergency warning broadcast reception signal output terminals 61 and 61 are provided, and when this is connected to an external device, it can be input as a no-voltage contact signal to the no-voltage contact circuit of the external device. It can be used to activate external devices such as.
