Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a warning light such as a rotating light or a flashing light equipped in an emergency or semi-emergency vehicle such as a police car or an ambulance, and a speaker equipped in the vehicle. The present invention relates to an improvement for facilitating continuous operation of a vehicle-mounted alarm device that generates a siren sound or broadcast.

(Prior Art) Emergency and semi-emergency vehicles such as police cars and ambulances are equipped with warning lights such as rotating lights and flashing lights, and speakers that emit warning sounds such as siren sounds and broadcast emergency guidance. A switch that activates the warning light and an amplifier with a warning sound function that drives the speaker are installed in the vehicle. The warning light, the speaker, and the amplifier with the alarm sound function were produced by different manufacturers, and these were mounted on the vehicle body by the bodybuilder. Therefore, the activation switch of the warning light (hereinafter referred to as a beacon switch) and the various control switches of the amplifier with an alarm sound function are separately installed in the vehicle, and therefore, the operator cannot operate the beacon switch and the amplifier with the alarm sound function. It was difficult to operate the control switch in a series of operations, and the operation was inconvenient.

In recent years, the number of equipment for emergency and semi-emergency vehicles tends to increase more and more, but many devices are swift and reliable even during busy times such as during driving of emergency and semi-emergency vehicles and / or during emergency and semi-emergency situations. Reliable operation is required. Moreover, the amplifier with the warning sound function must be installed within a range where it can be used by both the driver and the assistant, and the installation position is limited.

(Purpose of the Invention) The present invention eliminates the above-mentioned inconvenience and provides a warning light by a series of operations.
It activates the siren sound and broadcast to enable smooth emergency dispatch.

In addition, the present invention is equipped with a beacon switch in the same housing as an amplifier with an alarm sound function.
The control knobs of the amplifier are arranged on the same panel or substantially on the same plane to save space and make the operation convenient.

Further, the present invention is to provide an amplifier and a beacon switch with pilot lamps respectively so that the operating states of the amplifier and the warning light can be monitored.

(Embodiment) FIG. 1 shows a perspective view of an amplifier with an alarm sound function of the present invention. A beacon switch knob 3, a power switch knob 4, a tape input jack 5, a microphone are provided on a front panel 2 of an amplifier housing 1. A jack 6, a volume knob 7, and a siren switch knob 8 are arranged in a horizontal row. The panel 2 has a red pilot lamp 9 above the knob 3 and a green pilot lamp 10 above the knob 4.
Are arranged respectively.

FIG. 2 shows a block diagram of an amplifier with a warning sound function.

The terminal of the tape input jack 5 is input to the mixer 11, and the terminal of the microphone jack 6 is input to the mixer 11 via the microphone amplifier 12 and the microphone volume 13. For example, a first siren sound generation circuit 14 that generates a woo sound and a second siren sound generation circuit 15 that generates, for example, a fan fan sound are connected to interlocking switches 16a and 16b having two circuits and three contacts, and the switch 16a is a mixer. Entered in 11. The switch 16b is connected to the power switch 17. The interlocking switches 16a and 16b have a first siren sound terminal, a second siren sound terminal, and a neutral terminal between these terminals. The mixer 11 is connected to the main amplifier 18, and its output terminal is connected to the speaker terminals 19a and 19b.

The power line 20a of the main amplifier 18 is connected to the negative terminal 21a of the battery, the power line 20b is connected to the power switch 17,
It is connected to the positive terminal 21b of the battery via the fuse 22. A resistor 23 and an amplifier pilot lamp (LED) 24 are connected between the power supply lines 20a and 20b. Beacon switch 25 is connected to battery 27 and warning light 28 via terminals 26a and 26b. A resistor 30 and a beacon pilot lamp (LED) 31 are connected between a connection point 29 between the switch 25 and the terminal 26b and the negative terminal 21a of the battery. The lamp 24 is green and the lamp 31 is red.

The vehicle-mounted alarm device of the present invention is configured as described above and operates as follows.

The power switch knob 4 is pressed to turn on the switch 17 to put the amplifier in a standby state. At this time, the pilot lamp 24 lights up, and the green lamp 10 appears to light up on the panel, and the standby state is displayed.

Next, press the beacon switch knob 3 to switch 25
When is turned on, the circuit of the warning light 28 and the battery 27 is closed via the terminals 26a and 26b, and the warning light of the vehicle is turned on.
At the same time terminal 26a, switch 25, resistance 30, pilot lamp
31, terminal 21a, battery 27 circuit is closed, lamp 31
Lights up, the red lamp 9 on the panel lights up, and the lighting state of the warning light is displayed.

When the siren knob 8 is turned on, for example, to the first siren sound side, a DC voltage is supplied to the first siren sound generation circuit 14 by the circuit of the switch 16b, and the first siren sound generation that generates the woo-woo sound is generated. The circuit 14 operates, its output is input to the mixer 11 via the switch 16a, and the siren sound is generated from the vehicle-mounted speaker via the main amplifier 18 and speaker terminals 19a and 19b. When the knob 8 is turned on to the second siren sound side, a DC voltage is supplied to the second siren sound generation circuit 15 by the circuit of the switch 16b, and the second siren sound generation circuit 15 that generates a fan-fan sound operates. I do. The output is input to the mixer 11 via the switch 16a, and a siren sound is generated from a vehicle-mounted speaker via the main amplifier 18 and speaker terminals 19a and 19b.

When the output signal of the tape recorder is applied from the tape jack 5, the mixer 11, the main amplifier 18, the terminals 19a, 19
Played on the in-vehicle speaker via b.

Further, when an output signal of the microphone is applied from the microphone jack 6, the voice is broadcast from the in-vehicle speaker via the amplifier 12, the volume 13, the mixer 11, the main amplifier 18, and the terminals 19a and 19b.

(Effects of the Invention) Since the vehicle-mounted alarm device of the present invention is configured and operates as described above, a warning light activation switch (beacon switch) is provided.
Control knob 3, alarm sound start switch control knob 8, and amplifier control knob (power switch knob 4,
All three types of operation knobs such as the tape input jack 5, the microphone jack 6, and the volume knob 7) are arranged on the same panel of the amplifier. In the case of this embodiment, all the knobs are arranged in a line, so that the warning light Siren sound and loud sound broadcasting can be activated by a series of operations, and can be operated quickly and conveniently. Needless to say, the arrangement of the knobs is not limited to the above-described embodiment, and the arrangement of the knobs can be arbitrarily arranged to obtain the effect of the invention. Further, it is not necessary to arrange all the knobs on the same panel, and if they are substantially on the same plane, the operation becomes convenient.

Further, in the present invention, since the beacon switch 25 is housed in the amplifier casing, the casing of the beacon switch 25 is not necessary and the space can be saved. Therefore, it can be installed in a narrow space between the driver and the assistant.

Further, the warning light is mounted on the roof of the car, and it is difficult to confirm the lighting state. However, in the present invention, since the pilot lamp 9 is arranged immediately above the beacon switch knob 3, the operating state is easy. Can be confirmed.
