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 31 (see FIG. 9) that is attached to the sound collecting portion of the microphone. This structure consists of a substantially cylindrical hood portion 32 having elasticity, and a microphone-adhering body 33 for fixing the microphone-side opening at one end of the hood portion in close contact with the microphone. A sound deadening urethane 43 is attached to the hood 32, and the mouth-side opening 41 at the other end of the hood 32 is pressed against the user's mouth to produce a voice inside the hood.

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 32 via the microphone fitting body 33 that fits around the microphone. However, when vocalizing inside the closed hood 32, there is no way for the air to escape, so it is not possible to cover the nose with at least the mouth when singing. Moreover, with this technology, 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 passage, 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.

In this way, as for the microphone, using a handheld microphone that can be held with one hand, which is usually used, is significant in terms of normal sound characteristics and for practice. room remains.

The present invention is based on research into a soundproof microphone system that does not press against the user's mouth and occurs in a sealed space, and allows practice with a familiar hand-held microphone. To provide a soundproof microphone system that can be used even in a living space without worrying about neighbors.

The soundproof microphone system of the present invention includes a sealed soundproof case body having a microphone fixing portion for housing the microphone at a predetermined position inside and an opening/closing structure for allowing the microphone to be taken in and out; A mouthpiece that has an opening that penetrates the head part that picks up the sound of the microphone and is pressed against the mouth including the nose to seal the inside of the soundproof case body, and further the soundproof case body. It is partially composed of a muffling exhaust port having an air hole, the mouth part is pressed against the mouth, the sound of the mouth and nose is guided into the soundproof case body, and voice is generated in a closed state except for the muffling exhaust port. In this way, it is possible to speak naturally with your own microphone.

A second aspect of the present invention is characterized in that a handle for gripping the soundproof microphone system is provided on a part of the outside of the soundproof case body.

In claim 3, the soundproof case main body is provided with an insertion hole into which a hand is inserted in order to grasp the microphone fixed in the soundproof case main body, and when the hand is inserted, the space between the wrist and the insertion hole is sealed. Since it is configured with a wrist sealing member to hold the microphone directly and sing, you can practice as usual without being aware that you are using a soundproof microphone system.

Further, in claim 4, the sealing member is a glove for gripping the microphone, the wrist portion of the glove is fixed to the insertion hole, and the space between the wrist and the insertion hole is maintained in a sealed state by the glove-adhering member. there is

In claim 5, the fixing member for the microphone fixed inside the soundproof case main body is fixed inside the soundproof case main body, one end of which has a projecting portion outside the soundproof case main body, and is fixed to an appropriate microphone stand. It is also possible to practice singing freehand by configuring it so that it has a microphone stand fixing part.

In claim 6, in order to cover the nose and mouth, the lip portion is formed so that the faces facing the nose and mouth are formed in a substantially triangular or substantially elliptical shape, and are attached so as to be rotatable in the left-right direction. , The mouthpiece rotates even when the microphone is held from directly below or from the side, so the approximately triangular or approximately elliptical projection should always be aligned with the position of the nose and the mouthpiece should be in close contact. We are making it possible.

In claim 7, sound absorbing material is attached to the inside of the soundproof case main body, so that unnecessary reflected sound and the like can be absorbed in the soundproof case.

An embodiment of the soundproof microphone system of the present invention will be described based on the drawings. FIG. 1 is a side cross-sectional explanatory view showing a state in which a singer uses the soundproof microphone system of the present invention, and FIG. 2 is a front explanatory view showing the state of the soundproof microphone system of the present invention viewed from the front. It is a diagram. The configuration of a basic soundproof microphone system will be described below.

This soundproof microphone system 1 includes a microphone fixing portion 2 for housing a microphone 5 at a predetermined position inside, and a closed soundproof case main body 4 having an opening/closing structure for allowing the microphone 5 to be taken in and out. . The soundproof case main body 4 has an opening 6a penetrating therethrough facing the head part for picking up the sound of the microphone 5 housed in the soundproof case main body 4, and is pressed against the mouth to seal the inside of the soundproof case main body 4. and a muffler exhaust port 8 having an air hole in a part of the soundproof case main body 4, and the muffler exhaust port 8 is pressed against the mouth including the nose. 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 6 against the mouth toward the inside of the soundproof case body 4, the internal pressure does not rise and the practitioner can sing naturally from the nose and mouth.
The noise reduction exhaust port 8 is constructed as shown in FIG. 5, but the flow of sound from the noise reduction exhaust port entrance 8a to the noise reduction exhaust port 8b 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.

The soundproof case main body 4 may be provided with an appropriate handle (not shown) on the outside of the soundproof case main body 4 as shown in claim 2 of the present invention. When singing while holding the microphone 5 housed in the case body 4 by hand, as shown in FIG. A wrist sealing member 10a is provided to seal the space between the wrist and the insertion hole 9 when the wristband is inserted. The wrist sealing member 10a is made of silicon material and expands even when the hand is inserted, but when the microphone 5 is grasped, it wraps around the wrist and fills the gap between the insertion hole 9 and the wrist H to seal the inside of the soundproof case body 4. can be kept in

In addition to gripping with bare hands, as shown in FIG. 11 and the insertion hole 9 are fixed via a glove contact member 10b that seals the space between the wrist and the insertion hole 9. As shown in FIG. Specifically, the glove contact member 10b is made of a hard silicone material, and is tightly fitted in such a manner that the groove of the glove contact member 10b fits into the insertion hole 9. It is fixed to the member 10b with an adhesive or the like. The insertion hole 9, the wrist sealing member 10a, and the glove contact member 10b are not adhered with an adhesive or the like, but are detachably fixed in a tightly fitted state. This is because, as will be described later, it is desirable to make it detachable when the insertion hole is covered, or when the soundproof case main body 4 is opened by the opening/closing structure, particularly in the case of an embodiment of a glove.

Moreover, in order to grasp the microphone 5 through this glove 11, it is configured in a special shape. As shown in FIG. 6, a hole for holding the microphone 5 is provided in the center so that the microphone 5 can always be held regardless of whether the hand is inserted with the right hand or the left hand. It is designed so that users who practice singing can use it regardless of whether they are right-handed or left-handed.

One end of a microphone fixing portion 2 for housing a microphone 5 housed in the soundproof case main body 4 at a predetermined position is fixed inside the soundproof case main body 4 in order to support the weight of the soundproof case main body 4. Both must be firmly fixed. In order not to block air from escaping from the top hemisphere and the rear hemisphere of the microphone grip, a fastener with a narrow width (approximately 1 to 2 cm) is preferable. Moreover, a strong spring clip requires a width and is difficult for women to handle, so it is preferable to use a screw.

In addition, the microphone 5 is fixed and fixed in the soundproof case body 4, and one end of the microphone has a projecting part outside the soundproof case body 4, and has a microphone stand fixing part 12 fixed to an appropriate microphone stand. It is configured.

When using a microphone stand, as shown in FIG. 7, the microphone stand fixing part 12 is turned downward and fixed to the microphone stand support 14. Since there is no need to grip with a bare hand, a hole in the wrist sealing member 10a exists, so a separate sealing lid (not shown) or the like must be prepared. When using this sealing lid, the wrist sealing member 10a is removed, or in the case of the glove 11, the glove sealing member 10b is removed and pushed into the soundproof case body 4 so that the insertion hole 9 can be directly covered. is preferred.

In addition, the soundproof microphone system 1 can be used by using a microphone stand or holding the microphone 5 by hand. Moreover, when holding the microphone 5, the hand supports the microphone 5 from below, holds the microphone 5 from the side, or has a completely circular shape such as a substantially triangular shape or a substantially elliptical shape depending on whether the hand is right-handed or left-handed. Otherwise, as shown in the front view of FIG. 2, the mouthpiece 6 is constructed so that it can be rotated to the right or to the left to closely cover the nose and mouth.

Even if the mouthpiece 6 is fixed to the mouthpiece fixed plate 7 and the fixed plate 7 is rotatable with respect to the soundproof case main body 4, this rotation mechanism does not prevent the mouthpiece 6 and the fixing plate 7 from being attached to each other. may be circular and rotatable, but the configuration is not limited as long as at least the mouthpiece 6 is rotatable with respect to the soundproof case main body 4 .

Further, the soundproof case main body 4 has an opening/closing structure for storing and removing the microphone 5. As can be seen in FIGS. It is However, as can be seen in FIG. 2, the soundproof case main body 4 is not left-right symmetrical. Since the microphone stand fixing portion 12 is positioned as an extension of the microphone fixing portion 2 at the upper portion, the opening where the snap lock 3a exists is shifted to the right due to the problem of strength. As for the range of shifting to the right, the soundproof case main body 4 is manufactured by separately molding the right side and the left side in FIG.

Alternatively, the soundproof case body 4 of FIGS. 1 and 2 may be divided into two parts, the upper part and the lower part, and the hinge 3b and the snap lock 3a may be provided on the left and right sides. In the case of Embodiment 3 (claim 3) in which the glove sealing member 10b is attached, it is difficult to open unless the glove sealing member 10b is removed before opening the snap lock 3a, but there is no restriction on the opening/closing structure.

As described above, in the soundproof microphone system 1, an appropriate sound absorbing material such as urethane is attached to the inside of the soundproof case main body 4 so as not to generate an unnatural echo sound inside.

Further, the soundproof case body 4 of the soundproof microphone system 1 of the present invention is configured in a shape in which the central portion is cylindrical and narrowed from side to side as shown in FIG. The soundproof case main body 4 may be barrel-shaped as long as it is cylindrical and the mounting surface of the hinge can be made flat. Furthermore, if it does not affect the acoustic characteristics, it may be a cube. There are no restrictions on shape.

The cord 14 of the microphone 5 can be protruded from a cord ejection hole (not shown) previously provided when the microphone 5 is housed in the soundproof case body 4. A cord shield 15 having slits in the direction seals the inserted cord ejection hole.

The soundproof microphone system 1 is configured as described above, but by doing so, as shown in FIG. By connecting the microphone signal from the soundproof microphone system 1 to the audio interface 18 and listening with the earphone 19, the karaoke performance can be quietly enjoyed anywhere.

In the present invention, as a result of various studies, the lip portion 6 is adapted to cover the nose as well. Focusing on the fact that the singing voice is also emitted from the nose, in order to collect the natural singing voice that is usually sung, the microphone 5 housed in the soundproof case main body 4 is connected to the sound. A structure that can collect sound from both the nose and mouth with a single microphone without worrying about pressure is desirable.

The material of the soundproof case main body 4 in the soundproof microphone system 1 may be made of resin or paper. In particular, if it is made of paper, it is possible to use a slightly thicker case made by a molding method, which is lightweight and increases the soundproof effect. can.

Furthermore, in the case of the microphone 5 for personal use, especially in the case of a dynamic microphone, it functions as a sound collecting device unless it is structurally designed to exhaust toward the hemisphere at the tip of the grill bowl and the hemisphere in the latter half. is fatally lost.

Thus, in the soundproof microphone system of the present invention, the soundproofing function is effectively enhanced, the microphone 5 is made to function effectively, and the user can pick up sound in a natural state without being affected by internal pressure or the like. ing.

The present invention allows you to easily set the microphone with your familiar microphone and practice singing quietly anywhere without worrying about the surroundings, and even in situations where you have to stay at home. It is possible to provide a soundproof microphone system that enables natural vocalization practice with voice and is excellent in terms of mental health.
