開昭51−65609号公報参照）。(Prior Art) Conventionally, in a so-called hand-held electric megaphone, in which an amplifier section and a microphone section are connected to the rear side of a horn-shaped speaker section, and a handle is attached to the bottom surface of the amplifier section, the horn of this speaker section is attached to the front side. It is known that the opening is enlarged toward the front and that at least a portion of the opening is made of a transparent material (for example, see Japanese Utility Model Publication No. 51-65609).

づらいという問題点があつた。 However, even if you hold the steering wheel in your hand and bring your mouth close to the microphone located at the rear end and try to check what's ahead through the opaque horn, the transparent horn is formed on an inclined surface, so the visibility is limited. Especially when targeting specific people on the move, it is difficult to accurately track and amplify the target, making it difficult to accurately convey the content of the amplification message. The problem was that it was difficult and difficult to use.

An amplifier section and a microphone section are sequentially connected to the rear side of the speaker section, the speaker section has a horn, and the horn is made of transparent synthetic resin, and
A transparent window portion having a plane perpendicular to the inclined surface of the horn that is continuous with the upper surface of the amplifier portion is formed.

明ホーンを介して確認される。(Function) With this structure, when the megaphone is in use, the user's line of sight is almost orthogonal to the transparent plane window, allowing the user to see through the target in front without image distortion, and to direct the user toward the target. Accurate outgoing amplification is performed. In addition, the overall positional relationship can be confirmed through transparent horns other than the plane window.

ともに透明な合成樹脂で一体に形成されている。 In this electric megaphone, as shown in FIG. 1, an amplifier section 2 and a microphone section 3 are sequentially connected to the rear side of a speaker section 1, and a handle 4 is attached to the lower surface of the amplifier section 2. The speaker part 1 has a horn outer cylinder 5 which extends and opens while expanding in diameter toward the front.
Inside this horn outer cylinder 5, a horn middle cylinder 6 and a horn inner cylinder 7 are disposed coaxially in order to provide horns 5, 6, and 7 forming a folded sound path. The horn outer cylinder 5 and the horn inner cylinder 6 are integrally formed together with the connecting piece 8 from transparent synthetic resin.

である。 A viewing window portion 9 having a vertical plane is provided on the inclined surface of the horn outer cylinder 5 that is continuous with the upper surface of the amplifier portion 2.
is formed by sinking or protruding from the slope. As transparent synthetic resins, polycarbonate, cellulose, polyethersulfone, polymethylpentene, polypropylene, polysulfone, polystyrene, methacrylic, polyvinyl chloride, etc. can be used, but they have good impact resistance, weather resistance, injection moldability, dimensional stability, Considering the cost of rigid raw materials, etc., it is appropriate to use polycarbonate resin.

When the microphone is held in the hand and the mouth is brought close to the microphone part 3, the front can be seen through the transparent horn outer cylinder 5, so even when the listener or user is on the move,
Electric megaphone horn 5, 6, always in the right direction
7 can be aimed at, and the loudspeaker content can be accurately transmitted over a longer distance. Furthermore, since the front view is not obstructed during use, the listener's reactions and movements can be confirmed, making it easier to use. especially,
The viewing window 9 is a transparent surface that is almost orthogonal to the viewing direction, so the object viewed through it will not be optically distorted, and the direction of sound wave emission can be aligned with the target within the service area. It becomes easier.
