So-called karaoke boxes or karaoke rooms where people can enjoy karaoke have been established in various places, regardless of age or sex, and the karaoke boom is increasing. For example, in commercial karaoke machines, not only the echo function but also the spread of laser discs causes lyrics guides, singing / breathing guides, etc. to be displayed on a large screen, making everyone feel like a star. While being proficient, he can easily sing difficult songs.

As a microphone used in the karaoke apparatus or the like, a hand-held microphone is used which is composed of a substantially spherical head portion and a round bar-shaped grip portion, and which is generally pole-shaped. A windshield net formed by weaving a steel wire is attached to the head portion of the microphone. This windshield net is formed by combining hemispherical members that are divided into upper and lower parts, and is joined by a windshield net connecting ring member around the circumference of the joint portion.

By the way, a user's breath, saliva, sweat or the like is sprayed on the head of the microphone. In particular,
In a microphone used by an unspecified large number of people in the above-mentioned karaoke room or karaoke snack, etc., a large amount of user's breath, saliva or sweat is blown to the head part and is included in them. A large amount of saliva, small pieces of food, liquor, etc. will adhere.

When the microphone used by another person is anxious, some people wipe the head part with a dish paper or a handkerchief, but sometimes they use it, but most people use it without much concern. As described above, the windshield net is attached to the head of the microphone,
Since the user's breath, saliva, sweat, etc. sprayed on this head portion enter the inside from the stitches of the windshield net,
It is not easy to clean it by wiping the outside.

Therefore, there is a problem in that the microphone emits an offensive odor due to the user's breath, saliva, sweat, etc. sprayed on the head portion, and bacteria are propagated, which is extremely unsanitary.

In order to solve the problems of the microphone used by such an unspecified number of people, various ideas have been proposed in which a sterilizing means, an antibacterial means or an aroma means is provided in the microphone. For example, real fairness 1

There is. The microphone cover is formed in a cap shape and is attached so as to cover the head portion of the microphone.

[0009]

The idea of the microphone cover provided with the above-mentioned sterilizing means, antibacterial means or aroma means is, for example, Japanese Utility Model No. 1-36.
In No. 396 "Microphone Cover", the operation of wrapping the microphone head part in the center part with the base cloth as the inside and collecting the cross-shaped star-shaped side pieces in the grip part and binding them with rubber bands is It is extremely difficult for someone to do. In addition, by enclosing a disinfectant, a desiccant or an aromatic agent between the two sheets,
The head part becomes stiff and the thickness becomes large, resulting in poor usability. In addition, there are various problems such as the sheet being torn by mischief, etc., and the enclosed disinfectant, desiccant, fragrance, etc. enter the inside of the head part and cause a failure. It has not been realized.

[0010] Also, in the case of "Kaikaihei 4-55896" Mic Cover ", since it is mounted so as to cover the head part of the microphone, the operation is simple, but if the microphone is swung too much for singing, the head There is a problem that the folded microphone cover attached to the part comes off.

[0011] Therefore, the present invention has been proposed for the purpose of providing a microphone cover which is easy to handle and in which microphones used by an unspecified number of people are always kept clean. is there.
