- the vibration absorbing space 25 is formed between the charcoal sound absorbing layer 50 and the front plate 30 inside the unit cell 21.
- the sound wave is revolving in the inside) is configured so that the sound wave is lost while repeating the transfer of sound energy to the charcoal sound absorbing layer (50).
- the shape of the unit cells 21 in which the sound absorbing action as described above has the through-hole 35 as a narrow inlet, and forms a relatively wide space therein, such that some openings are like a resonance tube of an instrument. Except that the structure has a closed structure, so that the sound waves introduced into the unit cell 21 can be effectively lost by the charcoal sound absorbing material while roaming in the interior without going back to the room.
- the sound energy is transmitted to the charcoal granules 100 or the charcoal sound absorbing layer 50, the char particles received the sound energy in the process of extinguishing the sound pressure Fine vibrations are generated by this, and thus the charcoal particles can be expected to further promote the far-infrared emission and anion divergence effect of the charcoal.
- the present invention when the present invention is applied in the form of a door or the like to a place where strong sound is generated, such as an auditorium, a sound room, a movie theater, or the like, the sound generated indoors (that is, the vibration of the air) is narrow in the unit cell 21.
- the vibration generated indoors that is, the vibration of the air
- the far infrared and anion dissipation effects can be very high and the effect of the fragrance of the charcoal can be expected to spread into the room. It is more preferable because it is.
- FIG. 6 is a view showing a form in which the two configurations as described above, according to the charcoal granule 100 as shown in Figure 1 in the vibration-absorbing space portion 25 is provided as an empty space as shown in FIG. Can be configured to fill up.
- the charcoal granules 55 are more preferably configured to be easily vibrated by being filled in a non-bonded state without a binder or an adhesive, unlike the charcoal sound absorbing layer 50 formed by using a charcoal paste. Do.
- the charcoal sound absorption layer 50 smooth It may be made of one surface, but may be configured in other forms as illustrated in FIG. That is, for example, as shown in FIG. 7B, the center portion may be curved and concave, as compared with the peripheral portion. In this configuration, the surface area of the charcoal sound absorbing layer 50 becomes wider. Since the negative reflective surface converges toward the center, more efficient sound absorption is possible.
- the surface of the charcoal sound absorbing layer 50 may be roughly roughened to further increase sound absorption of the charcoal sound absorbing layer 50, or as shown in (c) of FIG.
- a protruding protrusion or embossing may be formed. Treatment of such embossing, grooves, etc. may be used in combination with the same shape as in FIG. 7 (b), and the treatment of the surface of the charcoal sound absorption layer 50 as described above may increase the sound absorption of the sound. It is also more effective in enhancing the promoting effect on the far infrared emission and the anion emission.
- the sound absorbing material is effectively collided and absorbed by the sound absorbing the charcoal sound absorbing as the room hovered within a certain unit cell space is very excellent Sound absorption and sound insulation can be produced.
- the existing door products are limited to a simple opening and closing function and, like glass, reflects most of the room sound, so that the reflection sound is excessively high, thereby reducing the indoor sound reverberation sound. It functions as a sound absorbing member, and in particular, some sound is reflected from the front plate 30 and some sound is absorbed through the through hole 35, so that an effect of qualitatively raising the room reverberation sound by controlling the appropriate reflection sound and noise absorption can be expected. have.
- the present invention in the process of absorbing the above-mentioned noise, the sound waves due to room noise hit the charcoal component to generate fine vibration by sound pressure, thereby promoting the emission of far infrared rays of charcoal.
- the effect can be obtained. That is, in the case of the previously developed charcoal-integrated products, it simply did not have a significant effect because there is no means for promoting the effect of charcoal simply by embedding charcoal, but according to the present invention as a sound absorbing material and far-infrared ray With the function of promoting the divergence of the advantage that can be solved the problem of the indoor air environment more effectively.
- the present invention can be widely used in the construction field such as interior sound absorbing boards and functional doors, and other various finishing materials or window materials.
