Description

Noise prevention resonator and installation method thereof {ANTI NOISE RESONATOR AND INSTALLATION METHOD THEREOF}

The present invention relates to a noise prevention resonator and a method of installing the same. More specifically, the resonator can be installed in the inner space of the ceiling or inner wall by a simple method, and a plurality of resonators can be installed using a corrugated structure and an adjustable length. It relates to a noise prevention resonator that can prevent noise generation by generating sound waves that selectively resonate with dog sound waves and a method of installing the same.

In general, wood plywood, gypsum board, synthetic resin materials, and metal are mainly used as finishing materials for buildings. Conventional finishing panels are mainly made of synthetic resin or light metal such as aluminum, and have a tubular base and side walls extending in all directions from the edges of the base.

In this way, the side wall portion of a conventional ceiling panel can be inserted and fixed into a clip mounted on a panel support member installed on the ceiling of a building. However, these ceiling panels have the limitation of aggravating indoor noise by reflecting most of them rather than absorbing voices and other noises generated in the installed room.

Accordingly, in order to eliminate or reduce such noise, various sound-absorbing materials are being used. The uses of sound-absorbing materials are generally divided into architectural and industrial purposes, and they are mostly used in combination with other materials and with component materials that play an auxiliary role.

Here, when using a sound-absorbing material to prevent noise, the sound absorption rate must be used as a selection criterion, and noise characteristics, use location, and use conditions must be taken into consideration.

These sound-absorbing materials include porous sound-absorbing materials, resonance-type sound-absorbing materials, and plate vibration-type sound-absorbing materials. Among these, resonance-type sound-absorbing materials utilize the resonance phenomenon of sound. To elaborate, by installing a resonant sound-absorbing material that resonates in the main frequency band of the generated noise at a predetermined location of the noise source, the noise can be canceled out using wave interference due to the phase difference between the generated noise and the resonating sound wave.

However, conventional resonance sound-absorbing materials are effective in canceling out sound waves of one or two or more frequencies, but do not properly respond to sound waves of multiple frequencies, so they do not sufficiently reduce noise. There was.

In particular, the key to preventing interfloor noise is to reduce low-frequency weight impact sounds, but conventional resonance-type sound absorbing materials were unable to effectively prevent low-frequency weight impact sounds.

Therefore, there is a need for a new noise-prevention resonance device and its installation method that can cover frequency bands other than the fixed frequency and thus reliably prevent noise generation.

It is provided to fully inform those who have the scope of the invention, and the present invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

This is a diagram schematically showing the resonance member shown in FIG. 2 being coupled to a sound-absorbing hole in the ceiling, and FIG. 4 is a modified example of FIG. 3.

As shown in these drawings, the noise-prevention resonator 100 according to an embodiment of the present invention is detachably coupled to the ceiling 110 (or inner wall) on which a plurality of sound-absorbing holes 110h for sound absorption are patterned. It may include a resonance unit 120.

Here, the resonance unit 120 is a plurality of resonance members 120a and 120b that are detachably coupled to the ceiling 110 and generate sound waves that selectively resonate with a plurality of sound waves of noise to remove a selected sound wave among the plurality of sound waves. may include.

With this configuration, it is possible to cover frequency bands other than the fixed frequency, thereby reliably preventing noise generation. In other words, noise may include sound waves having different frequencies, and in the case of the resonance unit 120 of this embodiment, it is possible to generate sound waves that resonate with each sound wave, thereby minimizing noise generation.

Describing each configuration, first, in the ceiling 110 of this embodiment, as shown in FIGS. 1 and 6, a sound-absorbing hole 110h for sound absorption may be formed in the thickness direction.

As sound waves of noise enter this sound-absorbing hole (110h), they can be absorbed. The sound-absorbing hole 110h is a cylindrical hole and has excellent sound absorption of sound waves in a relatively high frequency range. For example, sound waves in a low frequency range can be absorbed through the hole 110h of the ceiling 110, and thus noise generation can be prevented by removing sound waves in this frequency range.

As shown in FIGS. 1 and 6, a plurality of sound-absorbing holes 110h may be provided and formed in a certain pattern over the entire ceiling 110. As shown in FIG. 1, the plurality of sound-absorbing holes 110h may be arranged in a plurality of rows, so as to intersect with adjacent rows, that is, between the two sound-absorbing holes 110h of one row of the other adjacent row. It may have a structure in which one sound-absorbing hole (110h) is disposed. This can be understood through the patterning structure of the ceiling 110a shown in FIG. 6.

Alternatively, as shown in FIG. 6, a plurality of sound-absorbing holes 110h in the ceiling 110b may be provided in a checkerboard pattern (grid pattern). That is, a plurality of sound-absorbing holes 110h are arranged parallel to each other along one direction of the ceiling 110b, and a plurality of sound-absorbing holes 110h are arranged parallel to each other in a direction perpendicular thereto, thereby providing overall sound absorption. The pattern of the holes 110h may be a checkerboard pattern.

However, the arrangement structure of the plurality of sound-absorbing holes 110h is not limited to this, and it is natural that the arrangement structure may have a different pattern.

In this way, by forming the sound-absorbing hole 110h in the ceiling 110, noise generation can be reduced by absorbing certain sound waves within the noise.

Meanwhile, the resonance unit 120 of this embodiment can remove sound waves by generating sound waves that selectively resonate with each sound wave of noise having multiple sound waves. The resonance unit 120 of this embodiment may include a plurality of resonance members 120a and 120b provided in the shape of a corrugated tube, as shown in FIGS. 1 and 2.

Each resonance member (120a, 120b) has an overall cylindrical shape and is provided with regular wrinkles along the longitudinal direction, so that it can be stretched or shortened in the longitudinal direction by the wrinkles. Through this, the resonance members 120a and 120b can respond to a plurality of sound waves included in the noise.

For example, with respect to a first sound wave having a frequency of one band, the long resonance member 120a of FIG. 2 may generate a resonant sound wave to remove the first sound wave, or a second sound wave having a frequency of another band may be removed. With respect to sound waves, the short resonance member 120b of FIG. 2 generates a sound wave that resonates, thereby eliminating the second sound wave.

Likewise, sound waves having frequencies in other bands can also generate corresponding resonant sound waves by selectively adjusting the lengths of the resonance members 120a and 120b, and through this, the corresponding sound waves can be removed.

As shown in FIG. 2, the resonance members 120a and 120b of the present embodiment include a resonance body 121 provided in the form of a tube with an empty space formed inside and a corrugated portion 123 so that the length can be adjusted, It is provided at one end of the resonance body 121 and may include a coupling protrusion 125 coupled to the ceiling 110.

As described above, the resonating body 121 can be expanded or retracted by the wrinkled portion 123 of a wrinkled shape, thereby selecting the sound wave to be removed, and generating a sound wave that resonates with the selected sound wave to remove the corresponding sound wave. It can be removed.

Although not shown, the resonance body 121 may be provided with a resonance hole for resonance, and the sound wave may be introduced into the resonance body 121 by the resonance hole and the sound wave may be removed by resonance.

To elaborate, the resonance frequency of each resonance member (120a, 120b) of the above-described resonance unit 120 is, for example, dependent on the volume of the resonance body 121, the degree of wrinkles of the resonance body 121, or the diameter or depth of the resonance hole, etc. It can be decided by

In the conventional case, for this purpose, there was a complexity of having to manufacture the bodies forming the resonance part in different sizes. In the present embodiment, each resonance member (120a, 120b) having the same structure was stretched or shrunk using wrinkles to form each body. Since the resonance frequencies of the resonance members 120a and 120b can be adjusted, the structure can be simplified compared to the prior art, and each sound wave can be removed more reliably.

The resonance body 121 of these resonance members 120a and 120b can be coupled to the ceiling 110 using a coupling protrusion 125, as schematically shown in FIG. 3, and the coupling protrusion 125 is connected to the ceiling. By having a diameter corresponding to the sound-absorbing hole (110h) provided in (110), it can be fitted into the sound-absorbing hole (110h). However, it is not limited to this, and a separate coupling hole (not shown) may be provided in the ceiling 110, and the coupling protrusion 125 may be fitted into the coupling hole.

In addition, as schematically shown in FIG. 4, a separate guide tube 115 can be inserted into the sound-absorbing hole 110h or the coupling hole formed in the ceiling 110, and a coupling protrusion ( It is natural that 125) can be detachably combined.

These resonance members 120a and 120b may be arranged in various structures in the inner space of the ceiling 110. For example, as shown in FIG. 1, the resonance members 120a stretched out through wrinkles are positioned on the ceiling 110. The resonance members 120b, which are arranged along a straight line and folded through wrinkles to intersect them, may have a cross structure in which they are arranged along a straight line on the ceiling 110.

In Figure 1, the arrangement of the resonance members 120a and 120b having two lengths is shown and described in detail, but the longer extended resonance members or the shorter retracted resonance members can be appropriately placed on the ceiling 110. It is natural that it can be done.

Meanwhile, hereinafter, the installation method of the above-described noise prevention resonator will be described with reference to the drawings.

Figure 5 is a flow chart of the installation method of the noise prevention resonator of Figure 1, and Figure 6 is a diagram schematically showing each step of the installation method of Figure 5.

(S400) and may include a ventilation sheet attachment step (S500).

When each step is described with reference to FIG. 6, first, in the sound-absorbing hole forming step (S100) of this embodiment, a plurality of sound-absorbing holes (110h) for sound absorption are processed on the ceiling 110 or the inner wall to form a pattern. You can.

In the guide hole preparation step (S200) of this embodiment, a guide hole 10h for mounting the resonator 120 may be formed in the ceiling 110 or the inner wall. Through the guide hole 10h, the worker can access the inner space of the ceiling 110, and the resonator 120 can be mounted on the inner space of the ceiling 110 in the next resonator mounting step (S300). There is. Ceiling(110)

However, it is not limited to this, and of course, for example, a lighting fixture already installed on the ceiling can be removed and the resulting hole can be used as a guide hole.

Meanwhile, in the resonator installation step (S300) of this embodiment, the resonator unit 120 provided with resonance members 120a and 120b for resonance may be installed in the inner space of the ceiling 110. As described above, during the resonance unit mounting step (S300), the resonance members 120a and 120b mounted on the ceiling 110 generate sound waves that selectively resonate with a plurality of sound waves depending on the degree of wrinkles, thereby generating a sound wave selected from the plurality of sound waves. You can prevent noise by removing it.

In the guide blocking step (S400) of this embodiment, the guide hole (10h) is blocked, and through this, the installation of the noise prevention resonator 100 of this embodiment can be completed preferentially.

Meanwhile, in the ventilation sheet attaching step (S500) of this embodiment, a ventilation sheet (not shown) may be attached to the ceiling 110 or the outer surface of the inner wall to prevent the holed part of the ceiling from spoiling the aesthetics of the exterior. In the case of a ventilated seat, since noise can freely enter and exit, noise can be smoothly transmitted to the resonance unit 120, thereby preventing noise.

As such, according to an embodiment of the present invention, the resonator can be installed in the inner space of the ceiling or inner wall in a simple manner, and the resonator 120, which has a corrugated structure and can be adjusted in length, can be used to transmit a plurality of sound waves. Noise generation can be prevented by generating sound waves that resonate selectively.

In addition, since noise can be prevented by adjusting the length of the resonance members 120a and 120b having a single structure, the manufacturing process can be simplified compared to the prior art.

Meanwhile, hereinafter, a noise prevention resonator according to another embodiment of the present invention will be described, but description of parts that substantially correspond to the configuration of the sound absorption device of the above-described embodiment will be omitted.
