JPH07222272A - Chin strap fitted microphone - Google Patents

Abstract

PURPOSE:To provide microphone structure for preventing wind blowing noises or picking up the generated sounds of a mounting person by fitting the microphone into the elastic object of the chin strap of a helmet or a hat. CONSTITUTION:An elastic object 3 is fitted to a chin strap 2 fitted to a helmet 1. A double coated adhesive tape 5 is adhered to a microphone 4 and put into a prescribed position inside the elastic object 3 and the elastic object 3 and the microphone 4 are adhered. When the chin strap 2 is fixed with a chin strap 6 on the opposite side in the case of using this microphone, the installed microphone 4 is abutted to the side of the throat, the generated vibrations of the vocal chords are transmitted up to the microphone 4 as the vibrations by abutting the microphone 4 through the chin strap 2 and the thin elastic object 3 directly to the side of the throat. The whiz or noises are not inputted since the sound collection part of the microphone is covered with the chin strap 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a microphone attached to a chin strap so that noise other than that of the person concerned cannot enter.

[0002]

2. Description of the Related Art Conventionally, in mobile radio communication or in-vehicle communication (intercom), a microphone is a fleximble pipe fixed to a helmet, to which a microphone is attached at the tip of a flexible pipe, or a flexure fixed from a jig using a head. The thing which attached the microphone to the tip of the thimble pipe is known. There is also a throat type microphone since ancient times.

However, since this fleximble type microphone is installed in the front part of the mouth, external noise,
There were problems such as picking up wind noises and the like, which was a major obstacle to communication, and the structure for mounting the fleximble microphone was complicated and dropped, which interfered with driving the car.

Due to such a problem, it has not been used so much in a construction site where there is a large amount of noise and mutual communication while driving a motorcycle.

Further, in order to eliminate the drawbacks mentioned above,
There is also a throat type microphone, but in order to actually attach the microphone to the throat, a jig is wrapped around the neck and the microphone is applied to the microphone. The current situation is that there is no such product.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object thereof is to surround a microphone with an elastic body to prevent wind noise and to pick up a sound generated by a wearer. I am trying.

[0007]

[Means for Solving the Problems] Means of the present invention for achieving the above-mentioned object are as follows: a helmet or a hat having a microphone attached to the outside of the jaw strap, or an elastic member attached to the jaw strap. The microphone is attached to the configuration.

[0008]

The above structure will be described with reference to FIG. 1. Since the chin strap (2) is surrounded by the elastic body (3) and the microphone is mounted inside, the external noise and wind noise hardly enter the microphone. The microphone is applied directly to the side of the throat through the chin strap and thin elastic body, so that only the sound generated by the wearer is passed through.

[0009]

EXAMPLES Examples of the present invention will be described below.
The elastic body (3) is attached to the chin strap (2) attached to the helmet (1). (In general, it is attached as a cushioning material to motorcycles and car helmets.) The double-sided adhesive tape (5) is attached to the microphone (4) and put in a predetermined position in the elastic body to attach the elastic body and the microphone. To glue. There is also a method shown in FIG. 3 in which the microphone is directly attached to the chin strap by a simple method, although the noise prevention effect is poor.

[0010]

The present invention has the above-described structure, and when the chin strap (2) is stopped at the chin strap (6) on the opposite side when using this, the installed microphone hits the side of the throat and is generated. The vibration of the vocal cords is transmitted to the microphone as a result of the structure in which (3) and (2) are firmly applied. Microphone sound collection unit for wind noise and noise (2)
It will be blocked because it is blocked by.
