Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a microphone accommodating part in an electric megaphone.

Most of the micro hangers in conventional electric megaphones were simply an L-shaped metal fitting attached to the rear end of the main body case, so external objects could collide with the microphone hung on the L-shaped metal fitting. This puts an excessive load on these retaining parts, causing problems such as damage or the microphone coming off the hanger.

In addition, since the microphone cord's lead-out portion from the microphone case is also located outside the main body case along with the microphone, it is directly affected by external forces and bends, resulting in wire breakage.

In view of this, the present invention provides a microphone accommodating section consisting of first and second recesses having different depths and a microphone hanger in the rear part of the main body case, and connects the microphone and the cord pull-out section of the microphone. It is an object of the present invention to provide a structure of a microphone accommodating section in an electric megaphone, which protects the microphone from external force and prevents the microphone cord from being disconnected by being accommodated in both of the recesses.

Hereinafter, the structure of the present invention will be explained with reference to the drawings in terms of embodiments.

As shown in Figures 1 to 4, 1 is an electric megaphone;
A speaker section 4 formed by combining a horn unit 2 and a drive unit 3, a main body case 7 that houses an amplifier 5 and a battery 6 and is connected to the rear part of the speaker section 4, a battery contact plate 8, and a microphone accommodating section. 9, and the main part consists of a lid body 12 connected to the rear of the main body case 7 by a hinge 10 and an opening/closing tool 11, and a handle 13 attached to the upper part of the main body case 7. Become something.

The main body case 7 includes an inner wall body 14, an outer wall body 15, and a connecting body 7a.
, 7b, 7C, and 7d are integrally molded from ABS resin or other composite resin, and guide rails 16 are provided opposite to each other on the left and right inner sides of the inner wall body 14.

The guide rail 16 is configured to be inserted with an amplifier 5 having a printed circuit board 18 attached in parallel to an L-shaped chassis 17.

19 is a support leg that supports the electric megaphone. 20 is a curled cord whose one end is soldered to the printed circuit board 18, and a notch 21 provided in the inner wall body 14 and the outer wall body 15.
It is derived to the outside through.

A rubber bushing 23 is fitted into the notch 21 to prevent wear caused by sliding contact between the curl cord 20 and the notch 21.

One turn of the curl cord 20 is pushed into the space between the inner wall 14 and the outer wall 15, and the bent portion functions as a cord stopper.

Note that holes may be used instead of notches.

At the rear of the lid body 12, there is a first recess 2 in which a microphone cord pullout part 25 of the microphone 24 is mainly accommodated on the lower side.
6a, and the depth is deeper than the first recess 26a on the upper side,
A second recess 26 in which the upper half of the microphone 24 is housed
b are provided, and further a second recess 26b and a first recess 26 are provided.
from the approximate center of the stepped portion 28 formed by the second
A microphone hanger 27 with a T-shaped cross section extending from the fish part 26 b
is installed protrudingly.

Incidentally, the microphone hanger 27 is formed integrally with the lid body 12 by using resin.

The microphone 24 has a case formed with a zero-shaped engagement recess 29 that fits into the microphone hanger 27, and a leaf spring that elastically presses the microphone hanger 27 when the recess 29 is engaged with the microphone hanger 27. 30 is attached to prevent the two from coming apart.

Further, the car record 20 is pulled out from the center of the lower part of the case of the microphone 24 via a cord bushing 31.

Further, the microphone 24 slightly protrudes rearward from the microphone accommodating portion, so that it can be easily attached and detached.

Note that 32 is a hanging band that connects the speaker section 4 and the lid body 12.
It is attached to.

33 is a talk switch, and 34 is an electronic component mounted on the printed circuit board 18.

Next, the procedure for hooking the microphone 24 to the microphone hanger 27 will be explained.
7 and slide it downward.

Then, the plate spring 30 prevents the microphone 24 from detaching from the microphone hanger 27.

In this state, the microphone 24 is in the second recess 26b, and the cord pullout part 25 of the microphone 24 is in the first recess 26b.
6 It is stored in a.

Conversely, when removing the microphone 24, it is sufficient to simply slide the microphone 24 upward.

Therefore, since the microphone 24 is surrounded by the peripheral walls of the first and second recesses in the hooked state, almost no external force is directly applied to the microphone hanger 27.
The microphone 24 and the microphone hanger 27 are protected without applying excessive force to the engagement recess 29.

At the same time, since the microphone cord pull-out part of the microphone is also housed in the first four parts, no force is directly applied from the outside, and disconnection accidents are prevented.

Since the present invention is constructed as described above, it has the excellent effect of protecting the microphone and the microphone hanger from external forces and preventing their damage, as well as reducing disconnection accidents that tend to occur at the microphone cord pull-out section. have
