マイクなどを使用して、歌唱や演説、講義ならびに会議など行う際、周辺への唾液などの飛沫の飛散が起こってしまい、この飛沫が唾液臭や、感染症の感染源になってしまう恐れも考えられる。これの低減にはマスクなどを装着して行う事が望ましいが、マスクなどを装着した状態では、本来の音声が発声できなかったり、息苦しさを感じてしまう場合もある。When singing, giving a speech, giving a lecture, or holding a meeting using a microphone, droplets of saliva or the like may be scattered around, and these droplets may become a source of saliva odor or infectious diseases. Conceivable. To reduce this, it is desirable to wear a mask or the like, but when the mask or the like is worn, the original voice may not be uttered or the person may feel stuffy.

カラオケ装置を店舗に有し、利用者にマイクを使用して歌唱などを行わせる料飲店ならびにカラオケボックスなどでは、1本または2本程度のマイクを、料飲店では1店舗で、カラオケボックスなどでは1部屋の利用者で使いまわすのが通常である。At restaurants and karaoke boxes that have karaoke equipment in stores and allow users to sing using microphones, one or two microphones can be used at restaurants, at one store at restaurants, and at karaoke boxes. It is usually used by one room user.

集会ならびに会議や授業、会見などを開催する際、参加者に発言内容が行き渡るよう、マイクを使用して発言を行うなどの際には、1本または少量本数のマイクを参加者で使いまわすことが一般的である。Participants should use one or a small number of microphones when making remarks using microphones so that the content of their remarks can be distributed to participants when holding meetings, meetings, classes, and press conferences. Is common.

これら上記のような場面などでのマイクの使用は、不特定多数が使いまわすことになり、マイク自体が唾液や素手で持つことにより汚染されてしまったり、感染症などの感染源になる懸念があった。The use of the microphone in these situations such as the above will be reused by an unspecified number of people, and there is a concern that the microphone itself will be contaminated by holding it with saliva or bare hands, or it will become a source of infection such as infectious diseases. there were.

マイク本体の汚染の問題を解決するため、特許文献1では、マイク全体にカバーを取り付ける方法が開示されている。また、特許文献2では、マイク全体にカバーを取り付ける方法が開示されている。In order to solve the problem of contamination of the microphone body, Patent Document 1 discloses a method of attaching a cover to the entire microphone. Further, Patent Document 2 discloses a method of attaching a cover to the entire microphone.

特許文献1に記載のカバーは、マイク本体をすべてカバー内に納めてしまうことにより、マイク自体の汚染を防止するようにしている。
特許文献2に記載のカバーは、マイク本体の集音部分のみ、樹脂で作られたカバーを磁石によって取り付けて保護するようにしている。また、これに類する形態として、集音部のみの保護は、このほかにも布や紙などで覆って保護する手段が多数散見される。
The cover described in Patent Document 1 is designed to prevent contamination of the microphone itself by housing the entire microphone body in the cover.
As for the cover described in Patent Document 2, only the sound collecting portion of the microphone body is protected by attaching a cover made of resin with a magnet. In addition, as a form similar to this, there are many other means for protecting only the sound collecting portion by covering it with a cloth or paper.

発声時の飛沫防止の手段として、特許文献3に記載のような、一般的にマスクと呼称される物の装着が行われており、マスクの装着以外でカバーと類する物として、特許文献4に記載のような外部から身体を保護するような形態が存在する。As a means for preventing droplets at the time of vocalization, a thing generally called a mask is attached as described in Patent Document 3, and as a thing similar to a cover other than wearing a mask, Patent Document 4 describes it. There is a form that protects the body from the outside as described.

図5は、マイク集音部カバー15の各部を示す。マイク集音部カバー部03は、飛沫飛散防止カバー11の手指装着部02と同様の物により手指に取り付けるため、一般的に使用されているマイクの集音部を覆える適当な大きさあれば、マイク集音部カバー部03自体に、マイク本体へ取り付け方法などの実施が不要である。機能上、材質は発生した音声を阻害せずマイクへ伝達することのできる材質が望ましく、軟質な樹脂、紙などが適しているが、金属や硬質な樹脂でも製作できる。FIG. 5 shows each part of the microphone sound collecting part cover 15. Since the microphone sound collecting part cover part 03 is attached to the fingers by the same thing as the hand mounting part 02 of the splash scattering prevention cover 11, if it has an appropriate size to cover the sound collecting part of a commonly used microphone. It is not necessary to attach the microphone sound collecting unit cover unit 03 itself to the microphone body. In terms of function, it is desirable that the material be a material that can transmit the generated voice to the microphone without disturbing it, and soft resin, paper, etc. are suitable, but metal and hard resin can also be manufactured.

図6は、図3の状態にマイク集音部カバー15を実施した形態を示す。マイク集音部カバー15は、飛沫飛散防止カバー11とともに、手指12の右手人差し指の第2関節と指の付け根の間に取り付けた状態で、手前より、飛沫飛散防止カバー11、マイク集音部カバー15、マイク集音部カバー15の中にマイク13がある状態を表す。FIG. 6 shows a mode in which the microphone sound collecting unit cover 15 is implemented in the state of FIG.
