[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 This invention relates to a microphone cover.

[0002]

[Prior art]

 Although karaoke has become popular in recent years, an unspecified person uses one microphone in karaoke facilities such as karaoke rooms. In addition, in many cases, the microphone is placed close to the mouth to sing, and it is inevitable that saliva adheres to the sound collecting part of the microphone. As a result, there is a risk of contact with saliva of another person via the sound collecting part of the microphone, and not only the lack of cleanliness, but also the risk of transmission of an infectious disease. However, as a means for keeping the sound collecting section of the microphone clean, a method of wiping with a cleaning agent has been known, but wiping is time-consuming, and for karaoke using the same microphone while changing in a short time. not appropriate. Simple means are required.

[0003]

[Problems to be solved by the device]

 Wiping with the above-mentioned cleaning agent is not only time-consuming, but may be completely cleaned or may be insufficient due to the work of the person who wipes it, and it cannot be expected to completely eliminate the risk of infection. Therefore, the present invention is easy to handle and always obtains a certain level of cleanliness, and is intended to keep the microphone sound collecting section clean at low cost.

[0004]

[Means for Solving the Problems]

 In this invention, a microphone cover is attached to the periphery of a perforated sheet of a size that covers the sound collecting part of the microphone, by attaching a string around the body of the microphone to fix the perforated sheet to the microphone. is there. A sheet that covers the body of the microphone may be continuously provided on the peripheral edge of the porous sheet (claim 2). A non-woven fabric is suitable as the material for the porous sheet (claim 3), but porous paper, cloth, gauze or the like can also be used. Further, it is preferable that a bactericidal agent or an antibacterial agent is incorporated (Claim 4). The cord for fixing to the microphone may be a regular cord that is tied at the ends and fixed, but if it is an annular rubber cord, the workability of attachment and detachment is good (Claim 5).

[0005]

[Action]

 The microphone cover of this invention is used by fixing it to the sound collecting part of the microphone with a string, and it is exchanged at any time. Since the material that covers the sound collecting part of the microphone is a porous sheet, the sound collecting effect of the microphone is almost the same as when the cover is not attached, and there is no practical effect. In particular, since non-woven fabric is extremely flexible and lightweight, there is almost no noise due to contact between the sheet and the sound collecting part, and the surface is slightly fluffed. The sound collection part is kept clean because it prevents it from reaching the part. If the porous sheet contains a bactericidal agent or an antibacterial agent, a bactericidal or antibacterial effect can be obtained, so that the replacement interval of the cover can be made relatively long.

[0006]

[Embodiment of device]

 In the figure, a rubber cord 4 is sewn in an annular shape on the peripheral portion of a thin non-woven fabric 3 having a size to cover the sound collecting portion 2 of the microphone 1 to form the microphone cover of the present invention. The non-woven fabric 3 is a polypropylene non-woven fabric, and contains an antibacterial agent (for example, a metal ion such as copper ion as a component and exhibiting an antibacterial effect by sustained release of metal ions) or a bactericide. Microphones for karaoke generally have a spherical sound collecting part, and their sizes are almost the same. Since the non-woven fabric is slightly stretched, the non-woven fabric 3 can be used for most of the microphones for caraque, if a non-woven fabric suitable for the size of the sound collecting portion of an average microphone for caraque is prepared. Since the sound collecting portion is generally spherical, by winding the rubber cord 4 around the base of the sound collecting portion 2, the microphone cover is securely fixed and does not come off during use.

The microphone cover configured as described above is replaced at any time. For example, if the Karaoke facility provides this cover, it will be replaced and thrown away after each singer. Also, if an individual holds a special cover, they can attach their own cover when singing. Therefore, if a new cover or a cover for yourself is attached, the microphone can be used without being contaminated by other people's saliva, etc., and the risk of infection by various bacteria is eliminated.

Here, the effects of using the nonwoven fabric as the porous sheet are as follows. First, thin non-woven fabrics are extremely flexible and lightweight. When a microphone is used, it is unavoidable that the cover vibrates due to air pressure during vocalization and hits the sound collecting part of the microphone. If the cover is inflexible or heavy, the sound of vibration becomes loud and is picked up by the microphone as noise. However, if the nonwoven fabric is flexible and lightweight, the volume generated by the contact between the nonwoven fabric and the sound collecting part is negligible and can be ignored in practice. Moreover, since the nonwoven fabric has a high aperture ratio, the decrease in sound volume due to transmission through the cover is slight. Therefore, sound can be collected in substantially the same state as when the cover is not used, and noise is not mixed. Second, the non-woven fabric has fine fluffs on the front and back sides, which are not smooth. The fluff has the function of blocking the passage of saliva. That is, when the saliva of the microphone user adheres to the nonwoven fabric, if the surface of the cover made of vinyl is smooth, the saliva easily passes through the through hole and reaches the sound collecting part of the microphone. However, saliva is blocked by the presence of fluff, and it is difficult for saliva to permeate the cover, so that saliva is prevented from adhering to the sound collecting part of the microphone as much as possible, and the sound collecting part of the microphone is Always kept clean. Also, for the same reason, it is possible to prevent saliva adhering to the sound collecting part of the microphone from passing through the cover and adhering to the surface side. Therefore, saliva adhering to the microphone does not ooze out on the surface of the newly installed microphone cover, and cleanliness is ensured. Thirdly, a thin non-woven fabric has a property of being stretched strongly in tension. Therefore, even if the sound collecting part of the microphone is slightly larger than the size of the non-woven fabric, the non-woven fabric can be accommodated and mounted by stretching. That is, there is a wide allowable range of the size of the sound collecting part of the microphone that can be supported by one standard microphone cover. This leads to lower costs.

Next, the effect of incorporating a bactericidal agent or antibacterial agent into a porous sheet such as a nonwoven fabric is as follows. First, since a bactericidal action is obtained by including a bactericide, various bacteria contained in saliva attached to the porous sheet are sterilized. Therefore, a clean condition can be obtained without necessarily changing the cover each time the singer changes. This is especially effective when it is not possible to replace the cover with each alternate singer, such as when singing while turning one microphone in a group. Secondly, by the action of the bactericidal agent or the antibacterial agent, it is possible to sterilize the germs attached to the porous sheet during the storage of the microphone cover or suppress the growth thereof. Therefore, regardless of the storage condition, the new cover does not have bacteria attached to it, and can be used safely. Even if an individual has a dedicated microphone cover, there is no risk of germs growing during storage and it is kept clean. An antibacterial agent containing a metal ion such as copper ion has a high antibacterial effect in the presence of water. Therefore, the microphone cover, in which saliva is present, has a sufficient function of the antibacterial agent containing metal ions.

2 and 3, a body cover 6 that covers the body portion 5 of the microphone 1 is connected to the peripheral edge of the nonwoven fabric 3 that covers the ambient sound portion 2. Here, the non-woven fabric 3 and the body cover 6 may be integrally formed of one non-woven fabric, or may be sewn or bonded as separate bodies. Reference numeral 7 in FIG. 3 is a slit for facilitating attachment of the body cover 6. Since the body portion 5 of the microphone 1 is covered by the body cover 6, the microphone can be used without touching sweat or oil gripped by another person. It is preferable that the body cover 6 also contains an antibacterial agent or a bactericidal agent.

[0011]

[Effect of device]

 According to this invention, since the sound collecting portion of the microphone is covered with the microphone cover formed of the perforated sheet, it is possible to always use the microphone in a clean state by replacing the microphone cover. Therefore, there is no feeling of cleanliness during use and there is no risk of being infected by bacteria. Moreover, the clean state can be maintained only by attaching and detaching the cover, which is extremely simple and inexpensive because of the structure for attaching the string to the porous sheet.
