It is a groundbreaking invention that can be used in a variety of functions, such as being able to actively contribute to the present invention, which is very useful and convenient in practical use.

Hereinafter, the present invention for achieving the above object will be described in more detail based on the accompanying drawings.

As shown in the accompanying drawings, FIGS. 1A to 4, the front wall surface 120 and the left and right wall surfaces in which the open upper portion 110 and the sound absorbing hole 121 are sealed by the combination of the upper cover 200 are formed. 130) 140 and the soundproof block 100 of a predetermined size consisting of the rear wall surface 150 and the bottom surface 160 is injection molded with a synthetic resin,

The sound absorbing recombination unit 101 and the resonance plate coupling unit 102 are sequentially formed in the soundproof block 100 so as to be spaced apart from each other at predetermined intervals,

When the sound absorbing material 300 is coupled to the sound absorbing material coupling part 101 and the resonance plate 400 is coupled to the sounding plate coupling part 102, the first, second, and third air layers 100a before and after the sound absorbing material 300 and the resonance plate 400 are combined. ) 100b and 100c are formed.

Therefore, when external noise is introduced into the soundproof block 100, the sound absorbing material 300 significantly attenuates the noise of the high frequency sound range, and in the resonance chamber 400a provided in the resonance plate 400, the noise of the low frequency sound range is particularly innovative. At the same time, it assists to increase the attenuation efficiency of noise in a plurality of air layers, namely, the first, second, and third air layers 100a, 100b, and 100c, and breaks down the noise of the high frequency range as well as the low frequency range. Will be attenuated.

On the other hand, on the left side of the soundproof block 100, the left and right coupling protrusions 103 having locking projections 103a at both ends are formed.

On the right side of the soundproof block 100, left and right connection coupling recesses 104 are provided with locking recesses 104a at both ends,

The left and right connection coupling protrusions 103 formed on the left side wall 130 of the one soundproof block 100 are connected to the left and right connection coupling recesses 104 formed on the right side wall 140 of the other soundproof block 100. When combined, the locking projection 103a provided at the left and right coupling protrusions 103 is firmly coupled to the locking groove 104a provided at the left and right coupling recesses 104 so that a plurality of soundproof blocks 100 are connected to each other. It is installed long connecting to left and right.

In addition, the sound insulation blocks 100 are formed by recessing the outer surface of the lower end of the front wall surface 120, the left and right wall surfaces 130 and 140, and the rear wall surface 150 by a predetermined height inwardly of the soundproof block 100. Upper and lower laminated lower coupling portion 105 was integrally formed at the lower end.

Therefore, simply by coupling the lower coupling portion 105 for the upper and lower laminations of the one side soundproof block 100 to the open top 110 of the lower soundproof block 100, a plurality of soundproof blocks 100 very simply It can be laminated high up and down.

On the other hand, the bottom surface 160 of the sound insulation block 100 is formed to be inclined downward from the front wall surface 120 to the rear wall surface 150 and formed a foreign material discharge hole 161 in the rear of the bottom surface.

Therefore, rainwater or washing water is easily discharged together with dust.

In addition, a fixing protrusion 402 is formed at the rear of the resonance plate 400 in which the resonance chamber 400a is formed,

Protrusion fixing holder 106 was formed on the inner surface of the rear wall surface 150 of the soundproof block 100.

Therefore, when the resonance plate 400 is installed, when the fixing protrusion 402 is coupled to the protrusion fixing holder 106, the fixing force of the resonance plate 400 is increased, so that the resonance plate 400 is firmly and stably without moving left and right before and after. Can be fixedly installed.

Here, the resonance plate 400 may be configured in various forms, in the present invention, in particular, the entrance 401 is a semi-circular resonance chamber 400a of narrow width is formed,

A resonance plate 400 having a bent connection end 403 is formed at one end and a connection end insertion piece 404 is formed at one end of the ends bent in a semicircular shape in both front left and right directions from the inlet 401. Used.

Therefore, when the resonance plate 400 is installed, when the coupling end 403 formed on one resonance plate 400 is coupled to the connection end insertion piece 404 formed on the other resonance plate 400, the resonance plates 400 are semi-lattice forms. It can be installed long connecting left and right.

In addition, the present invention forms a resonance plate lower end sealing portion (162a) is coupled to the lower end of the resonance plate 400 is sealed on the bottom surface 160 of the soundproof block 100,

The bottom surface 160, the bottom of the resonance plate 400 is coupled to the upper end of the resonance plate upper end sealing portion (162b) was formed.

Therefore, when the sound insulation blocks 100 are stacked up and down, the upper and lower ends of the resonance plate 400 are sealed by the lower end seal 162a and the upper end seal 162b of the resonance plate without any gap, so that noise is not lost. It is completely attenuated.

Meanwhile, the sound absorbing material 300 used in the present invention may be formed of various materials and structures, but in the present invention, the sound absorbing material 300 made of a polyester material in which an aluminum chip 301 is mixed in an irregular arrangement is used. use.

Therefore, since the external noise introduced into the sound absorbing material 300 made of polyester material causes diffuse reflection by the mixed aluminum chip 301 in an irregular arrangement, the noise attenuation efficiency is increased and the noise (especially the noise of the high frequency range) is dramatically increased. Attenuated.

When the soundproof block 100 of the present invention configured as described above is installed around a road by connecting a plurality of up, down, left, and right as shown in FIG.

External noise is introduced into the soundproof block 100 through the sound absorbing hole 121 formed in the front wall surface, and passes through the first air layer 100a to the sound absorbing material 300.

Then, in the sound absorbing material 300, the noise of the high frequency sound range is first filtered.

In this case, when the sound absorbing material 300 is made of a sound absorbing material 300 made of a polyester material in which an aluminum chip 301 is mixed in an irregular arrangement therein, external noise introduced into the sound absorbing material 300 is mixed in an irregular array. Since the diffuse reflection is caused by the chip 301, the noise of the low frequency range is partially attenuated, so that the noise attenuation efficiency is increased and the noise (especially the noise of the high frequency range) is significantly attenuated.

Meanwhile, the first attenuated noise through the sound absorbing material 300 is partially attenuated by the resonance plate 400 connected to the left and right in a semi-lattice structure while passing through the second air layer 100b, causing partial reflection again. The rest is introduced into the resonance chamber 400a through the narrow entrance 401 in front of the resonance chamber 400a provided in the resonance plate 400.

Then, the noise in the low frequency range, which is the main source of the noise, is transformed into a new out-of-phase oscillation of the waveform from the standing wave, resulting in phase cancellation for a specific frequency, thereby eliminating or attenuating the standing wave. The noise is attenuated by the car.

The remaining noise attenuated in the resonance chamber 400a (the reverberation generated by the vibration of the resonance chamber 400a) is formed between the resonance chamber 400a and the rear wall 150 of the soundproof block 100. Attenuation in the air layer 100c in the fourth order.

As a result, the soundproof block 100 of the present invention is not only easy to install the soundproof wall around the road because it is easy to assemble up and down, or to connect left and right, the sound absorbing material ( Not only the noise of the high frequency band by 300 is canceled, but also the noise of the low frequency band by the resonance chamber 400a provided in the resonance plate 400, and the first, second, and third air layers 100a and 100b therebetween. ) 100c, the noise is canceled, so the noise canceling efficiency is further maximized.

In addition, the bottom surface 160 of the sound insulation block 100 is formed to be inclined downward from the front wall surface 120 to the rear wall surface 150, and the foreign matter discharge hole 161 is formed in the rear of the bottom surface, so that the soundproof block ( 100) When rainwater or washing water flows into the inside, it is easily discharged through the foreign matter discharge hole 161 together with the dust.
