본 고안은 피아노의 울림판(향판)외측에 피아노음을 방음시킬 수 있도록 구성한 방음판을 부착하여 연주장소가 아닌 주택가에서 피아노를 칠때 주위의 사람에게 소음공해를 일으키지 않도록한 것이다.The present invention attaches a soundproof plate configured to soundproof the piano sound outside the sounding board of the piano so that it does not cause noise pollution to people around when playing the piano in the residential area instead of the playing place.

종래의 피아노는 피아노의 뒤울림판이 개방되어 있기때문에 피아노를 칠때 피아노선에서 발생한 음의 진동이 후면의 울림판에 의하여 확대되어 울림공간을 통해 외부로 퍼지기 때문에 이웃집까지 피아노소리가 크게 들리게 되므로 피아노 소리를 싫어하는 사람에게는 소음공해가 되는 불편이 있고, 그랜드 피아노와 같은 대형 피아노의 경우는 유리섬유와 보호-시트로 접합구성된 흡음판을 공명판 뒤쪽에 당접시키고 있지만 외부와 완전밀봉이되지 않아서 방음효과를 얻을 수가 없는 불편이 있었다.In the conventional piano, since the backing plate of the piano is open, when the piano is played, the vibration of the sound generated from the piano line is enlarged by the backing board and spreads out through the ringing space, so the piano sounds to the neighboring house, so the piano sounds For those who do not like it, there are inconveniences of noise pollution. In the case of large pianos such as grand pianos, the sound-absorbing plate made of glass fiber and protective sheet is abutted on the back of the resonance plate. There was inconvenience.

본 고안은 위와같은 종래의 결점을 시정하기 위하여 안출한 것으로 울림판의 외측에 방음판을 부착하여 피아노 소리가 외부로 크게 울려퍼지는 것을 막아 이웃주민에게 소음피해를 주지 않도록한 것인데, 이를 첨부도면에 의거 상세히 설명하면 다음과 같다. 스티로폴 발포수지제 가림판(1)의 내면에 스폰지로된 흡음판(2)을 접착하여 방음판(가)을 구성하고 이를 피아노(4) 뒤울림판(5)의 윤곽테(4a)에 접착테이프(3)로 접착하여 울림공간부(5a)가 외부와 완전히 구획되게 밀봉시킨 구조이다.The present invention was devised to correct the above-mentioned drawbacks, and by attaching a soundproof plate on the outside of the sounding board to prevent the sound of the piano from ringing out loud to the neighboring residents so as to avoid noise damage to the neighbors. The explanation is as follows. A sound-absorbing plate 2 is formed by adhering the sound absorbing plate 2 made of sponge to the inner surface of the styropol foamed resin blocking plate 1, and the adhesive tape 3 is attached to the contour frame 4a of the pitching plate 5 of the piano 4. It is a structure in which the ringing space portion 5a is sealed to be completely partitioned from the outside by adhering with a).

이와같이된 본 고안은 방음판(가)의 구성이 스티로폴 발포수지제로된 가림판 (1)이므로 제조하기 쉽고 가벼운 이점이 있으며 내면에 스폰지판으로된 흡음판(2)을 접착하였기 때문에 피아노 뒤울림판의 외측에 설치하여 외주를 윤곽테(4a)에 접착시키면 뒤울림부가 완전히 밀봉되어 피아노를 치게되면 뒤울림판에서 울려나오는 음의 진동이 스폰지판으로 된 흡음판(2)에서 바로 흡수되어서 음의 진동이 확대될수 없고, 스티로폴 발포수지로된 가림판(1)에 차단되므로 울림공간(5a)외부로 음이 퍼져나오지 못해 음이 외부로 확산되는 것을 막아 소음공해를 줄일수 있으며, 방음이 필요치 않을때는 접착테이프(3)를 박리하고 방음판(가)을 제거할 수 있기 때문에 피아노를 손상시키지 않고 방음을 할수있어 실용적이고, 안전한 이점이 있는 것이다.The present invention has the advantage that it is easy and easy to manufacture because the soundproof plate (A) is made of styropol foamed resin, and the sound-absorbing plate (2) made of sponge plate is adhered to the inner surface to the outside of the piano lapping plate. When the outer periphery is attached to the contour frame 4a by the installation, the rim is completely sealed and when the piano is played, the vibration of the sound coming out of the hoop is absorbed directly from the sound absorbing plate 2 made of sponge, so that the vibration of the sound cannot be expanded. Since it is blocked by the screening plate (1) made of styropol foamed resin, the sound does not spread outside the sounding space (5a), preventing the sound from spreading to the outside, and reducing the noise pollution. Since it is possible to peel off the soundproof plate and remove the soundproof board, it can be soundproofed without damaging the piano.
