Description

TECHNICAL FIELD The present invention relates to a soundproof microphone system that can be used in living spaces such as vocal practice and karaoke without worrying about neighbors.

So far, many instruments have been proposed as silent instruments, such as soundproof pianos combined with electronic circuits, trumpets with muted bells, and saxophones that cover the entire instrument. has hardly been done, and for example, as a few examples, the one shown in Patent Document 1 has been proposed.

This patent document 1 proposes a microphone cover 51 (see FIG. 8) that is attached to the sound collecting portion of the microphone. This structure consists of a substantially cylindrical hood portion 52 having elasticity, and a microphone-adhering body 53 for fixing a microphone-side opening at one end of the hood portion in close contact with the microphone. A sound deadening urethane 63 is adhered thereon, and the opening 41 on the other end of the hood portion 52 is pressed against the user's mouth, so that the voice is produced inside the hood portion.

However, this is welcome in that a previously owned microphone can be used by fixing the head (sound collecting part) of the microphone in the hood part 52 via the microphone fitting body 53 that fits around the microphone. However, when vocalizing inside the closed hood 52, there is no way for air to escape, so at least the mouth is not covered with the nose when singing. Moreover, with this technique, when the user speaks, the internal pressure increases and the voice does not sound natural, and the voice becomes muffled. It was practically difficult to sing and I couldn't even raise my voice.

Therefore, in Japanese Patent Application Laid-Open No. 2002-100001, the voice must include not only the voice from the mouth but also the sound from the nose, but this point was not taken into consideration. However, prior to this Patent Document 1, as the technology of Patent Document 2, an oral microphone 4 was placed in a funnel-shaped sound collecting device that covers the mouth, and air escapes when the user speaks from the mouth or vagina. A tail tube 15 is disclosed. Further, as for the sound from the nose, a technique is disclosed in which the nasal microphone 3 provided outside the funnel is used to collect the sound.

In the case of Patent Document 2, since there is an air escape route, it is easy to vocalize, a more natural voice can be obtained, and the sound deadening property is also excellent. As described above, in Patent Document 2, the nasal microphone 3 on the outside of the funnel and the oral microphone 4 on the inside of the funnel collect sounds separately. Since the collected sound is not a mixture of the collected sounds from the nose and mouth, it is felt that the vocalization is not natural.

Prior to describing the present application, patent document 3 already filed by the applicant of the present application will be described. As shown in FIG. 22 and a closed soundproof case body 24 having an opening/closing structure that allows the microphone 25 to be taken in and out is formed. It has an opening 26a penetrating the microphone 25, which is housed in the soundproof case main body 24 and faces the head portion that picks up the sound of the microphone 25, and is pressed against the mouth to seal the inside of the soundproof case main body 24. and a muffler exhaust port 28 having an air hole in a part of the soundproof case main body 24. Other than that, it is configured to generate voice in a sealed state.

As a result, even if the practicer sings by pressing the mouth part 26 against the mouth toward the inside of the soundproof case body 24, the internal pressure does not rise and the practitioner can sing naturally from the nose and mouth. The noise reduction exhaust port 28 is configured as shown in FIG. 6, but the flow of sound from the noise reduction exhaust port entrance 28a to the noise reduction exhaust port 28b is indicated by arrows for convenience, and air flows in and out in both directions. can come and go. As for the sound, a nested reflector is installed inside, and the internal sound is attenuated and discharged to the extent that it leaks a little, but the sound leakage is almost unnoticeable. Conventionally known muffled exhaust ports can be used.

Also, as shown in FIG. 5, the glove sealing member 30b has a glove 31 disposed thereon for gripping the microphone 25, and a wrist portion of the glove 31 and the insertion hole 29 for fixing the wrist portion of the glove 31 to the insertion hole 29. 29 is fixed via a glove contact member 30b that seals the space between them.
