DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric
megaphone in which a handle is connected to a base and formed in a rod shape. Traditionally,
electric megaphones are used in places where mass gatherings or demonstrations take place to
help protect the dangers of security and mobs, most of which are microphones or connections to
trumpet shaped or pot shaped bodies Electric megaphone. Therefore, if the microphone and the
megaphone body are separately provided in the case of (1) lnl), it is often difficult for the mob
itself and the mob to fight against dangerous materials when they are attacked by the mob . In
order to respond to such circumstances, the present invention conventionally provides the abovementioned electric megaphone by providing the electric megaphone which is effective when the
security guard is possessed with a baton or it is necessary to use both the baton and the electric
megaphone simultaneously. The purpose is to meet the demands of the security personnel. In
other words, the speaker part and the body part are formed in a rod shape of substantially the
same diameter, and a small diameter cylindrical handle is extended at the rear end of the body
part. It is an object of the present invention to provide an electric megaphone having a function
as a protective armor by providing a protective mask at the opening end of the speaker to
improve the strength. Hereinafter, the configuration of the present invention will be described
with reference to the drawings. The electric megaphone 1 has a cylindrical speaker portion 2 in
which a body portion 3 which is slightly tapered rearward is continuously provided, and a
cylindrical handle 4 (2) smaller in diameter than the body portion is provided at the rear end of
the body portion. A cruciform protective mask 5 is provided at the open end of the speaker

section, which is extended by a spring joint 14. Each of the above parts is formed of steel to
improve strength, but may be formed of synthetic resin to reduce weight and facilitate
processing and assembly. The microphone switch 6, the volume controller 7, the alarm switch 8
or the handle 4 is provided in the rear of the body 6 so as to be close to the handle 4, and the
handle 4 is held to perform these operations. Connected by code 1o. In addition, the handle 4 has
a slightly enlarged diameter at its rear end to prevent slipping, and a band (not shown) is
attached to the rear end to be put on the neck or shoulder. The speaker unit 2 has a folded horn
structure as shown in FIG. 3, and the drive unit 11 is connected to the rear. An amplifier 12 is
built in the body 3, and the microphone cord 10, the microphone switch 6, the volume controller
7 and the alarm switch 8 are connected to the amplifier. In the back wall of the handle 4, a screw
(3) pulling contact terminal 16 is attached, and the battery 14 is held by being pushed by the
contact plate 15, and the contact plate is connected to the amplifier.
The protective mask protects the inner cylinder 16 and the inner cylinder 17 provided in the
speaker unit 2 and further forms a rib 18 of the evening book in a cross shape in order to
reinforce the outer wall (outer cylinder) of the speaker unit. However, in some cases the number
of ribs may be increased and in some cases it may be formed into a net shape. The microphone 9
is formed to be curved, and provided at one end thereof with a clamp 19 having a spring
installed therein, and fixed to a hat, a helmet or the like. The microphone may be wireless to
facilitate moving the megaphone. In the present embodiment, the speaker portion, the body
portion and the handle may be circular in cross section, square or other shapes. The above
electric megaphone is usually used as a megaphone by operating the microphone switch 6 and
the volume controller 7, and used as an alarm by operating the alarm switch 8 when notifying
danger or repelling a mob (4) Can be used as a protective armor in case of fire, earthquake, etc.
or when attacked by a mob. As described above, the present invention can not be used as a
regular electric megaphone, and can be used as a protective armor or a threat tool in a very
special case, so it can be used for general lectures. Also, there is an excellent effect that it can be
widely used when, for example, suppressing a mobbed group in disasters such as earthquakes
and typhoons.
