Soundproof Acoustic Microphone Device

One embodiment of the present invention relates to an acoustic microphone device capable of soundproofing.

In general, even if the public wants to practice singing and speaking, it is not easy to find a soundproof place, that is, a studio or other soundproof walls, so that a user can practice singing and speaking by installing a microphone in a room in a private house or apartment.

However, in the above case, due to the large amount of ambient noise, it was necessary to provide noise pollution to the surrounding people, causing frequent friction.In order to solve this problem, it is necessary to pay a considerable cost and to perform the practice by constructing a soundproof wall or soundproofing place. It is true that it is not easy for the general public to solve this aspect.

Eventually, a soundproof microphone was proposed to perform singing and speaking practice in a normal house or apartment without noise pollution.

One embodiment of the present invention provides an acoustic microphone device capable of soundproofing to enhance the sealing and to eliminate the feeling of friction. That is, in the present invention, the shape around the mouth changes from time to time when the song is changed from time to time, but the general soundproof microphone is unnatural due to the feeling of pressure due to the strong contact of the microphone body around the mouth for closeness, but in the present invention, cushion packing is applied. Cushion immediately adapts to minute changes around the mouth, improving contactability and providing a sound-proof acoustic microphone device that can relieve pressure and stuffiness with natural cushion contact.

It provides a sound microphone capable of soundproofing to increase the attenuation efficiency of the sound and vibration by the structure to install a plurality of attenuating pipes at regular intervals.

In addition, an embodiment of the present invention provides an acoustic microphone device capable of soundproofing having a volume control panel function. That is, in the present invention, the smaller the intake / exhaust mechanism through which the sound collected by the mask portion exits, the greater the attenuation effect, but the user is frustrated because of the remaining volume that is not lost. If the intake and exhaust vents are large, the exhaust volume is high but the sound attenuation function is considerably lowered. As a solution to this problem, the sound is high at high pitched sound, but the volume is small. Since the volume is low and the air intake / outlet is wider than that of the high sound, it is less affected by the attenuation rate.

When the cushion packing 111 is in contact with the face surface around the lips, the cushion reaction occurs well even at a small pressure so as not to give a pressure to the face, which may be detached to the inside of the body 120 to be described below.

In addition, the plate-shaped sound absorbing material 112 has a substantially flat plate shape, which can be detached inside the cushion packing 111. For example, but not limited to, the plate sound absorbing material 112 may be a sponge. This plate-shaped sound absorbing material 112 also performs a soundproofing role, can be replaced from time to time in hygiene. The material of the plate-shaped sound absorbing material 112 may be equally applied to other sound absorbing materials to be described below.

As such, one embodiment of the present invention provides an acoustic microphone device 100 capable of soundproofing which can enhance the sealing property and eliminate the frictional feeling. That is, in the present invention, the shape around the mouth changes from time to time when the song is minutely changed, but the general soundproof microphone is unnatural due to the feeling of pressure due to the strong contact of the microphone body around the mouth for close contact, but in the present invention, the cushion packing 111 in the mask.

The size of the air intake and exhaust 123 may be the same as the size of the air intake and exhaust 133 formed in the plurality of sound attenuation tubes 130 to be described below.

In addition, a thin opening degree control plate 124 may be further formed in the intake and exhaust mechanism 123 for attenuating the sound of the body part 120, but the opening degree adjustment plate 124 is also not limited thereto. It may be formed into a triangle, square, rectangle, pentagon, hexagon, heptagon, polygon or circle. The opening degree adjustment plate 124 is not limited, for example, but may have a form such as a diving board or a leaf spring that one side is fixed to the body 120 and the other side is free to rotate. Also, by way of example, but not limitation, the aperture control plate 124 may have a range of approximately 0.01 mm to 1 mm, preferably 0.06 mm to 0.6 mm, although the thickness varies depending on the material.

If the opening degree adjusting plate 124 has a thickness of less than about 0.01 mm, the opening degree of the intake / exhaust 123 may be opened so that the opening degree of the intake / exiting mechanism 123 is about 90% or more. If is greater than about 1 mm does not bend at a relatively large volume can be opened to about 10% or less of the opening of the intake and exhaust mechanism 123. The characteristics of the thickness of the aperture control plate 124 may be equally applied to other aperture control plates 134 to be described below.

In addition, a plurality of sound absorbing irregularities 125 for attenuating the sound may be further formed on the bottom surface 122 of the body part 120. Such a plurality of sound absorbing concave-convex portions 125 may further increase the sound attenuation and sound insulation efficiency by contacting the plate-shaped sound absorbing material 112 described above. For example, but not limited to, the plurality of sound absorbing irregularities 125 may have a semicircular shape, a triangle shape, a square shape, and the like, and the roughness may be about 1 μm to about 1000 μm.

In addition, the body portion 120 may further include a plurality of ring-type protrusions 126 formed to couple the plurality of sound attenuation tubes 130 to the rear surface of the bottom surface 122. The ring-type protrusion 126 may be formed in a substantially oval shape, a closed curve, or an open curve shape, which may be formed in a shape in which a circumferential length gradually increases from the center portion to the outside portion. The protruding height of the ring-type protrusion 126 may have a range of about 1 mm to 10 mm so that the plurality of sound attenuating tubes 130 and the cover 140 do not fall out after being combined.

The body portion 120 is, for example, but not limited to, silicone resin, polyvinyl chloride resin, polystyrene resin, polyethylene resin, polypropylene resin, acrylic resin, nylon, phenol resin, amino resin, epoxy resin, and the like. It may be formed of a synthetic resin. Here, the material may be applied to both the sound attenuation tube 130, the cover 140, and the handle 150 disclosed in the present invention. Moreover, this material can be applied to all the

mask portions

110, 210 and 310 disclosed in the present invention.

The plurality of sound attenuation tubes 130 may be coupled to the rear of the body portion 120 to attenuate the user's sound in a secondary and multistage manner. To this end, the plurality of sound attenuation pipe 130 each includes a side surface 131 and the bottom surface 132, similar to the body portion 120 described above, the air intake and exhaust formed in the bottom surface 132 for sound attenuation Sphere 133 may be further included. In addition, the sound attenuation tube 130 may further include a thin opening control panel 134 installed on the intake and exhaust 133. In addition, the sizes of the air intake and exhaust openings 133 and the opening adjustment plate 134 formed in the plurality of sound attenuation pipes 130 are the same as the sizes of the air intake and exhaust openings 133 and the opening adjustment plate 134 formed in the body portion 120. can do.

Each of the plurality of sound attenuation tubes 130 may be coupled to and fixed to each of the ring-type protrusions 126 formed at the rear of the body portion 120. Here, one or several sound attenuation tubes 130 may be separated from the rear of the body portion 120 and may not be coupled according to a user's need. Therefore, the user may use only the appropriate number of sound attenuation tubes 130 in combination with the ring-type protrusions 126 formed on the rear surface of the body 120 according to the required sound insulation level.

On the other hand, the plurality of sound attenuation tube 130 may have a form in which the circumferential length and height gradually increase from the center to the outside. That is, the circumferential length and height of the sound attenuating tube 130 located at the innermost are the smallest, and the circumferential length and height of the sound attenuating tube 130 located at the outer thereof are the circumferential length of the inner sound attenuating tube 130. And slightly larger than height. In this way, the circumferential length and height of the sound damping tube 130 located at the outermost side is the largest.

As such, one embodiment of the present invention provides an acoustic microphone device 100 capable of soundproofing which can enhance the sound attenuation function. That is, in the present invention, when the barrier ribs are independently formed at a predetermined interval from two or more thin plates than the soundproof structure of one thick plate, the vibration is reduced and the soundproofing efficiency is good. Due to the structure of installing a plurality of sound attenuating tubes 130 with a predetermined interval as described above provides an acoustic microphone device 100 capable of soundproofing to increase the attenuation efficiency of sound and vibration.

In addition, according to an embodiment of the present invention, the acoustic microphone apparatus 100 capable of soundproofing has openings and

adjustment plates

124 and 134 formed in the body 120 and / or the plurality of sound attenuation tubes 130 and the intake and exhaust direction of the user. The bending direction and the bending angle are automatically adjusted according to the amount of intake and exhaust. That is, when the user performs the intake operation, the outside air is inhaled through the intake and

exhaust vents

123 and 133. At this time, the opening

degree control plates

124 and 134 naturally bend in the intake direction. In addition, when the user performs the exhaust operation, the sound and air from the user are exhausted through the intake and

exhaust vents

123 and 133. At this time, the opening control plates 12 and 4134 naturally bend in the exhaust direction. In particular, when the displacement by the user is relatively small, the bending angles of the

aperture control plates

124 and 134 are relatively small, and when the displacement by the user is relatively large, the opening angles of the

adjustment plates

124 and 134 are relatively large.

In other words, the

aperture control plates

124 and 134 bend in the intake direction when the user intakes and bend in the exhaust direction when the user exhausts to open the intake and

exhaust mechanisms

123 and 133, but at the first bending angle when the user exhaust amount is the first exhaust amount. When the user's exhaust amount is the second exhaust amount larger than the first exhaust amount, the opening degree of the intake and

exhaust mechanisms

123 and 133 is autonomously adjusted by the second bending angle larger than the first bending angle.

As such, one embodiment of the present invention provides an acoustic microphone device 100 capable of soundproofing having an aperture control function. That is, in the present invention, the smaller the intake and

exhaust mechanisms

123 and 133 through which the sound collected by the mask unit 110 escapes, the larger the attenuation effect, but the user is frustrated because of the remaining volume that is not lost. Increasing the intake vents 123 and 133 increases the discharge volume, but the sound attenuation function is significantly lowered. Cursor should be small, but the pitch is low when the voice is low and the volume is large, so the attenuation rate is less affected even if the air intake / outlet (123, 133) is wider than when the voice is high. Thin

opening control panel

124 and 134 are installed on the 123 and 133 so that the

opening control panel

124 and 134 can be opened in both directions when discharging or inhaling according to the volume level. Acoustic microphone device 100 that can be soundproof by discharging and breathing naturally to eliminate the user's frustration to provide.

That is, the cover 140 also includes a side surface 141 and the bottom surface 142, the ring type projection 126 formed on the outermost side of the rear surface of the bottom surface 122 of the body portion 120 It can be coupled to and fixed to. In addition, a sound absorbing material 143 may be installed on the bottom surface 142 of the cover 140, and also a plurality of small through holes to allow sound and air to escape or air to enter approximately the center of the bottom surface 142. A plurality of 144 may be formed.

The handle 150 is coupled to approximately the center of the rear surface of the bottom surface 142 of the cover 140, which may be formed in a substantially cylindrical shape. For example, the handle 150 has one side open, the other side has a plurality of through-holes 152 may be formed in a cylindrical shape closed. In addition, the sound absorbing material 151 is built in the inside of the handle 150, so that the soundproofing efficiency is improved. Of course, the handle 150 is coupled to a region corresponding to the plurality of through holes 144 formed in the cover 140.

Figure 3a is a rear view showing the rear of the body portion 120 shown in Figures 2a and 2b, Figure 3b is a front view showing the interior of the sound attenuation tube 130 shown in Figures 2a and 2b, 3C is a cross-sectional view of the handle 150 shown in FIGS. 2A and 2B.

As shown in FIG. 3A, an intake and exhaust mechanism 123 may be formed at an approximately center of the bottom surface 122 of the body part 120, and the intake and exhaust mechanism 123 may have a bending direction and bending depending on the intake and exhaust direction and volume. An opening in which the angle is automatically adjusted may be formed in the control plate 124. In addition, the body 120 may include a plurality of mutually spaced protrusions 126 formed in a substantially elliptic type or a ring type on the rear surface of the bottom surface 122.

In addition, as illustrated in FIG. 3B, the sound attenuation tube 130 may include a side surface 131 and a bottom surface 132, and an intake and exhaust mechanism 133 may be formed at approximately the center of the bottom surface 132. The opening and closing control plate 134 may be formed in the intake and exhaust mechanism 133 to automatically adjust the bending direction and the bending angle according to the intake and exhaust direction and the volume.

In addition, as shown in Figure 3c, the handle 150 is in the form of a pipe open in the longitudinal direction, the sound absorbing material 151 may be coupled to the inside.

In addition, although not shown in the drawings, the embodiment of the present invention may further include a microphone installed in the body portion 120, which may be communicatively connected to the external acoustic device in a wired or wireless manner. In addition, the embodiment of the present invention may further include a wired or wireless control function attached to any one surface of the cover 140. Moreover, the embodiment of the present invention may further include an LED installed in the cover 140 and synchronously reacts to the sound.

4A and 4B are partial cross-sectional views illustrating an operating state of the aperture control panel 134 of the acoustic microphone apparatus 100 capable of soundproofing according to an embodiment of the present invention.

Soundproof sound microphone device 100 according to an embodiment of the present invention is the intake and

exhaust mechanisms

123 and 133 formed in the body portion 120 and / or a plurality of sound attenuation tube 130, and formed in the intake and exhaust mechanisms (123, 133) The opening may also include

throttle plates

124 and 134. Here, the opening

degree control plate

124, 134 may be adjusted in the bending direction and the bending angle according to the intake and exhaust direction and the intake and exhaust (ie, volume) by the user.

Here, the opening degree adjustment plate 134 formed in the intake / discharge mechanism 133 is demonstrated. In addition, when the opening degree control plate 134 is, for example, in the form of a square, only one side is coupled to the intake vent 133, and the other three sides are spaced apart from the intake vent 133 by a predetermined interval. Of course, the configuration and operation of the opening adjustment plate 124 also formed in the intake and exhaust mechanism 123 is also the same as the configuration and operation of the adjustment plate 134 is also formed in the intake and exhaust mechanism 133.

Specifically, as shown in FIG. 4A, when the user performs an intake operation, external air is intaken through the intake and exhaust vent 133, and the opening degree control plate 134 naturally bends in the intake direction. Here, the wide arrow direction is the intake direction.

In addition, as shown in FIG. 4B, when the user performs an exhausting operation (ie, when singing, practicing voice, or speaking loudly), the sound and air from the user may cause the air intake and exhaust mechanism 133 to move. The exhaust plate is then vented through the control plate 134 naturally in the exhaust direction. At this time, when the displacement by the user is relatively small, the bending angle of the opening degree adjustment plate 134 is relatively small, and when the displacement by the user is relatively large, the opening angle is also relatively large by the bending angle of the adjustment plate 134. That is, the opening degree control plate 134 is bent in the exhaust direction when the user exhausts to open the intake and exhaust mechanism 133, when the user's exhaust amount is the first exhaust amount is bent at the first bending angle and the user's exhaust amount is greater than the first exhaust amount When the second exhaust amount is bent at a second bending angle larger than the first bending angle, the opening degree of the intake and exhaust mechanism 133 is autonomously adjusted. Here, the wide arrow direction is the exhaust direction.

In this way, the user is comfortable breathing when using the soundproof microphone device 100 does not suffer from difficulty in breathing, and also the soundproofing efficiency of the soundproof microphone device 100 is automatically adjusted in accordance with the user's displacement and volume, Ease of use is improved.

As shown in FIG. 5, the acoustic microphone device 100 according to the embodiment of the present invention may be mounted and used in the headset 200. For example, but not limited to, the cover 140 may be connected to the headset 200 through the connection bar 201. Of course, a microphone (not shown) in the microphone device 100 may be electrically connected to the headset 200 through the connection bar 201.

Therefore, the user can listen to music through the headset 200, and can sing or practice speaking through the sound-providing acoustic microphone device 100, thereby improving convenience in use.

As shown in FIG. 6A, the soundproofing acoustic microphone device according to another exemplary embodiment of the present invention is different from the above-described mask part 110 (cushion packing) in the mask part 210 (particularly, cushion packing). It may have a structure.

It may include a support portion 213 in close contact.

Here, the cavity of the annular tube 211 may be further filled with, for example, a filler 212 such as, but not limited to, air, gel, and the like. The size of the tube 211 is greater than the thickness of the side portion 121 of the body portion 120, so that the tube 211 is in contact with the face surface first compared to the side surface 121 of the body portion 120. This is preferable.

In this way, as shown in FIGS. 6B and 6C, when any region of the tube 211 of the mask portion 210 is pressed, the upper and lower portions of the mask 212 other than the pressed point of the internal filling 212 that are not closed out are pressed. As it is pushed to any other point left or right, it comes into close contact with the face, so that the soundproof microphone device naturally closes the gap even if it is shaken.

Thus, for example, the shape around the mouth often changes minutely when singing, while the conventional soundproof microphone is unnatural due to the feeling of pressure due to the strong contact of the microphone body around the mouth for close contact, but cushion packing as in the present invention If you apply it to the cushioning of the mouth and the change around the mouth and up, down, left and right shake of the microphone is immediately adapted to improve contactability, and the natural cushion contact to solve the pressure and stuffiness.

As shown in FIG. 7, the acoustic microphone device capable of soundproofing according to another embodiment of the present invention is different from the above-described mask parts 110 and 210 (cushion packing) in the mask part 310 (particularly, cushion packing). It may have a structure.

For example, the mask part 310 may include an elastic contact surface 311 that gradually becomes concave from the outer side to the inner side, an elastic bending surface 312 that is bent to extend substantially in a “C” shape from the elastic contact surface 311, and It may include a support portion 313 extending from the elastic bending surface 312 is in close contact with the side surface 121 and the bottom surface 122 of the body portion 120.

In this way, the elastic contact surface 311 of the mask portion 310 is primarily in close contact with the face surface to perform sound insulation, and the "C" -shaped elastic bending surface 312 is bent freely in accordance with the movement of the face surface Do not let the sound leak out. That is, when singing, the shape around the mouth changes from time to time, and the concave elastic contact surface 311 and the "C" shaped bent surface 312 is such a slight change around the mouth and up, down, left, right of the microphone Adapt immediately to shaking to improve contact with the face.

What has been described above is only one embodiment for implementing the soundproofing acoustic microphone device according to the present invention, the present invention is not limited to the above-described embodiment, as claimed in the following claims of the present invention Without departing from the gist of the present invention, one of ordinary skill in the art will have the technical spirit of the present invention to the extent that various modifications can be made.
