Abstract

PROBLEM TO BE SOLVED: To amplify conversation while radiating illumination light in a water disaster rescue at night so as to attain effectiveness as against an urgent situation by arranging an illumination light capable of forward illuminating at an external end part of an in-megaphone cylindrical body. SOLUTION: When a talk switch 7 is drawn by a forefinger, etc., a phone speaker part 1 is turned to a target and someone talks by voice with a degree to permit lips to touch a microphone part 3, a voice signal from the microphone part 3 is amplified from the phone speaker part 1 so as to be uttered. Volume is adjusted by a volume adjusting equipment. When a signal switch is depressed regardless of the drawing operation of the talk switch 1, signal sound, etc., such as siren sound and a pistol sound, etc. is amplified by a signal sound generating circuit and given. Since the illumination light 5 is arranged at the external end part of the in-phone cylindrical body 1b, illumination light can be radiated forward so that conversation is amplified while radiating illumination light of the illumination light 5 and utterd in water disaster rescue, etc., at night.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric megaphone used for, for example, water rescue, traffic control, and personnel guidance.

[0002]

2. Description of the Related Art Conventionally, as this type of electric megaphone, a structure having a horn speaker section, an amplifier section, a microphone section and a handle section is known.

However, when the voice signal is transmitted to the microphone unit, the voice signal is amplified by the amplifier unit and is emitted from the horn speaker unit.

[0004]

However, in the above-mentioned conventional structure, when it is used at night, for example, a flashlight for illuminating light and an electric megaphone are to be carried at the same time. It is blocked and it is very inconvenient for other simultaneous work, and sometimes I forget to carry a flashlight, so I can not say effectively in situations such as water rescue where it is time-consuming. There is an inconvenience that sometimes.

SUMMARY OF THE INVENTION The present invention is intended to solve such a problem, and in the invention according to claim 1 of the present invention, a horn speaker section, an amplifier section, The horn speaker unit includes a microphone portion and a handle portion, and the horn speaker portion includes a horn outer cylinder body and a horn middle cylinder body disposed inside the horn outer cylinder body. It is an electric megaphone characterized by having possible lighting.

The invention according to claim 2 is characterized in that a lighting switch for lighting or extinguishing the illuminating lamp according to claim 1 is arranged in the vicinity of the handle portion.

[0007]

1 to 3 show an embodiment of the present invention, in which 1 is a horn speaker section, 2 is an amplifier section, and 3 is an amplifier section.
Is a microphone section, 4 is a handle section, and the horn speaker section 1 is provided with a horn outer cylinder 1a and a horn middle cylinder 1b arranged inside thereof.

Reference numeral 5 denotes an illuminating lamp, which is the cylindrical body 1 in the horn.
A lighting switch 6 which is built in at the outer end of b and is capable of irradiating the illumination light forward and which turns on or off the illumination lamp 5 is provided near the handle portion 4.

The handle section 4 is provided with a talk switch 7, the amplifier section 2 is provided with a volume controller 8 and a signal switch 9, and the microphone section 3 is provided with a plurality of dry batteries 10.

In this case, the electric circuit is, as shown in FIG. 3, a horn speaker unit 1, a microphone unit 3, a dry battery 10, an amplifier circuit 11 in the amplifier unit 2, a signal sound generating circuit 12, a signal switch 9, a talk switch 7, and illumination. A lamp 5 and a lighting switch 6 are provided respectively, and an audio signal from the microphone section 3 is amplified and emitted from the horn speaker section 1 only when the talk switch 7 is triggered.
When the signal switch 9 is pressed irrespective of the trigger operation of the talk switch 7, the signal sound or the like is amplified by the signal sound generation circuit 12 and is emitted.

Since this embodiment has the above structure,
Pull the talk switch 7 with your index finger or the like, aim the phone speaker unit 1 at the target, and speak with a voice that your lips touch the microphone unit 3 lightly. The volume is adjusted by the volume controller 8, and when the signal switch 9 is pressed regardless of the trigger operation of the talk switch 7, the signal sound generation circuit 12 causes a signal sound such as a siren sound or a pistol sound. Is amplified and emitted. At this time, since the illuminating lamp 5 is arranged at the outer end of the tubular body 1b in the horn, it is possible to irradiate the illuminating light forward, and thus at night. At the time of water rescue of
A conversation can be amplified and emitted while illuminating the illuminating light of the illuminating lamp 5, and a target can be illuminated by illuminating the illuminating lamp 5 for effective conversation transmission and carrying a flashlight at the same time. It will not be blocked by both hands, and it will not be obligatory to carry a flashlight, so it will be very effective in situations such as water rescue where you are competing for the moment. Since the horn is provided at the outer end of the cylindrical body 1b, it does not hinder sound emission and storage and storage, and can be used comfortably.

Further, in this case, since the lighting switch 6 for turning on or off the illumination lamp 5 is arranged in the vicinity of the handle portion 4, the illumination lamp 5 can be turned on or off while the handle portion 4 is held. It can be done and the comfort of use can be increased.

The present invention is not limited to the above-described embodiment, and for example, in the above-mentioned embodiment, the horn speaker unit 1, the amplifier unit 2, and the microphone unit 3 are sequentially connected. However, it can be applied to an electric megaphone in which the microphone unit 3 is detachably configured,
In addition, a rechargeable battery may be used as the power source, and the specific structure of the electric circuit, the disposition position of the lighting switch 6 and the like are appropriately changed and designed.

[0014]

As described above, according to the present invention, when the speaker portion is aimed toward the target and the microphone portion is spoken with a voice that is lightly touched by the lips, the voice from the microphone portion is output. The signal is amplified from the horn speaker unit by the amplifier unit and is emitted. At this time, since the illuminating lamp is arranged at the outer end of the horn middle cylinder, it is possible to irradiate the illuminating light forward. Therefore, at the time of a rescue operation at night, for example, it is possible to amplify the conversation while illuminating the illumination light of the illumination lamp and to speak, and to illuminate the target by illuminating the illumination lamp, which is an effective conversation. With the transmission, there is no need to carry a flashlight at the same time, both hands are not blocked, and it is no longer obligatory to carry a flashlight. In Una situation is very effective,
Further, since the illuminating lamp is provided at the outer end of the cylindrical body of the horn, it does not interfere with the sound emitting action and the storage and storage, and can be used comfortably.

Further, in the invention according to claim 2, since the lighting switch for turning on or off the illumination lamp is arranged in the vicinity of the handle portion, the illumination lamp is turned on or turned on while holding the handle portion. It is possible to turn off the lights and improve the comfort of use.

As described above, the intended purpose can be sufficiently achieved.
