본 고안은 전자악기에 있어서, 음을 발생시키는 건반에 이중의 접점 방식을 채용하여 음의 강약 조절을 할수 있도록 한 전자악기의 이중접점 장치에 관한 것이다.The present invention relates to a double-contact device of an electronic musical instrument in the electronic musical instrument, which adopts a double contact method to the keyboard for generating sound, so that the intensity of the sound can be controlled.

종래의 전자악기에 채용된 건반장치는 건반의 저면부에 누름부를 형성하고 이에 접점부를 형성하며 접점부에 접점되는 고무 스위치는 프린트 기판에 설치토록되어 있었는바, 이와같은 종래의 것은 고무 스위치와 접점부의 구성이 복잡하게되어 있었고, 작은 부품들로 구성되어 있어 이들의 제작, 조립작업이 난해하게 되었으며, 또한 건반의 복귀를 위한 별도의 복귀스프링등을 구비해야 하므로서 보다 양질의 음, 강약 조절이 곤란한 점동의 문제점이 있었다.The keyboard device employed in the conventional electronic musical instruments is to form a pressing portion on the bottom of the keyboard, and to form a contact portion thereon, and a rubber switch contacting the contact portion is installed on the printed board. The parts are complicated, and they are made of small parts, making them difficult to manufacture and assemble. Also, it is difficult to control the sound quality and strength by providing a separate return spring for returning the keyboard. There was a problem of viscous.

본 고안은 상기와같은 문제점을 감안하여 이중접점 방식의 탄력편을 채용하므로서 보다 효과적인 음의 강약을 조절할 수 있도록 하고 구조 또한 간단하게 구성하며 건반의 복귀를 상기 탄력편으로서 이룰수 있도록 안출한 것으로 이를 첨부한 도면에 의거하여 상세히 설명 하면 다음과 같다.In view of the above problems, the present invention adopts a double contact type elastic piece so that the effective sound intensity can be adjusted, the structure is also simple, and the return of the keyboard can be achieved as the elastic piece. When described in detail based on one drawing is as follows.

작동공(2)과 걸림부(3)를 형성한 샤시(1)의 일측에 힌지공(4)을 형성하고, 이에 힌지홈(6)과 걸림편(7) 및 누름부(8)를 가진 건반(5)을 회전승강 가능하게 설치한다.A hinge hole 4 is formed at one side of the chassis 1 in which the operating hole 2 and the locking part 3 are formed, and the hinge hole 6 and the locking piece 7 and the pressing part 8 are formed. The keyboard (5) is installed to be rotatable.

상기 샤시(1)의 저면에는 접점탄소막(14), (15)을 갖는 프린트기판(13)을 체결설차하되 프린트기판(13)에는 탄력편(9)을 고정설치한다.The printed circuit board 13 having the contact carbon films 14 and 15 is fastened to the bottom of the chassis 1, and the elastic piece 9 is fixed to the printed board 13.

탄력편(9)에는 도면의 표현상 우측부에 벤딩부(10')를 형성하고, 좌측부에는 절곡부(10)를 형성시켜 이 절곡부(10)의 우측과 좌측에서 제1 및 제2전성 실리콘 고무(11), (12)를 하측으로 설치 구성하여서 된것이다.The elastic piece 9 has a bending portion 10 'formed at the right side in the representation of the drawing, and a bent portion 10 is formed at the left side, so that the first and second conductive silicons are formed at the right and left sides of the bent portion 10. The rubbers 11 and 12 are installed downward.

그리고, 상기의 탄력편(9)은 전기가 통하지 않는 부도체로 형성되어 있다.The elastic piece 9 is formed of an insulator through which electricity does not pass.

이상과 같이 구성된 본 고안은 제2도와 같은 상태에서 건반(5)을 누르면 샤시(1)의 힌지공(4)에 걸려있는 건반(5)의 힌지홈(6)에 의하여 건반(5)의 일측이 회전 하는 상태로 하강하게 되고 이에 따라 누름부(8)가 하강하여 탄력편(9)의 좌측선단을 누르게된다.The present invention configured as described above has one side of the keyboard 5 by the hinge groove 6 of the keyboard 5 hanging on the hinge hole 4 of the chassis 1 when the key 5 is pressed in the state shown in FIG. This rotates to the lowered state and accordingly the pressing portion 8 is lowered to press the left end of the elastic piece (9).

탄력편(9)의 선단이 누름부(8)에 의해서 벤딩부(10')를 중심으로 하강하게 되면, 제1도전성 실리콘 고무(11)가 프린트기판(13)의 접점탄소막(15)에 접속하게 되며 상기 제1 및 제2전성 실리콘 고무(11), (12)가 각기의 접점탄소막(14), (15)에 접속되는 시간차에 반비례하여 음의 강약이 조절되면서 발성하게된다. 그런데, 상기에서 제1 및 제2전성 실리콘고무(11), (12)가 각기의 접점탄소막(14), (15)에 시간차를 두고 접속되는 이유는 탄력편(9)의 좌측에 상향으로 경사지게 절곡부(10)를 형성하였기 때문이다.When the tip of the elastic piece 9 is lowered about the bending part 10 'by the pressing part 8, the 1st conductive silicone rubber 11 is connected to the contact carbon film 15 of the printed circuit board 13. The first and second conductive silicone rubbers 11 and 12 are inversely proportional to the time difference connected to the respective contact carbon films 14 and 15, so that the negative strength and weakness are controlled. However, the reason why the first and second conductive silicone rubbers 11 and 12 are connected to the respective contact carbon films 14 and 15 with time difference is that the first and second conductive silicone rubbers 11 and 12 are inclined upward on the left side of the elastic piece 9. This is because the bent portion 10 is formed.

한편, 누르던 건반(5)을 놓게되면 탄력을 가진 탄력편(9)은 벤딩부(10')를 중심으로 탄발력이 발생되고 이의 탄발력이 건반(5)의 누름부(8)에 전달되어 건반(5)의 복귀되며 복귀완료시에는 걸림편(7)이 상기 샤시(1)의 걸림부(3)에 걸려 복귀시의 한계점을 제어하게되고, 탄력편(9)과 누름부(8)는 샤시(1)의 작동공(2)위치에서 작동된다.On the other hand, if you release the pressed key (5), the resilient piece (9) having elasticity is generated by the elastic force around the bending portion 10 'and its elastic force is transmitted to the pressing portion (8) of the keyboard (5) When the return of the keyboard 5 is completed and the return is completed, the locking piece 7 is caught by the locking part 3 of the chassis 1 to control the limit point at the time of return, and the elastic piece 9 and the pressing part 8 Is operated in the operating hole (2) position of the chassis (1).

한편, 상기와같이 작동하는 탄력편(9)을 몰드(MOLD)물에 탄력을 부여하여 이용할 수도 있고, 탄성을 가진 금속재로도 할 수 있다.Meanwhile, the elastic piece 9 operating as described above may be used by imparting elasticity to the mold (MOLD) water or may be a metal material having elasticity.

그런데, 상기의 탄력편(9)은 전기각 통하지 않는 부도체로 형성한다.By the way, the elastic piece 9 is formed of an insulator that does not pass through the electric angle.

이상과 같은 본 고안은 별도의 복귀스프링이나 복잡한 구성의 고무스위치장치가 필요없이 간단한 구조의 이중접점을 가진 탄력편을 설치하므로서 음의 강약을 보다 효과적으로 조절할수 있고, 또한 복귀력이 우수할 뿐만아니라, 제작 및 작업공수가 종래에 비하여 월등히 절감되는 점등의 특징을 지닌 것이다.The present invention as described above, by installing a resilient piece having a double contact of a simple structure without the need for a separate return spring or a complicated rubber switch device, it is possible to more effectively control the negative strength and strength, as well as excellent return force. , The manufacturing and workmanship is characterized by the lighting is significantly reduced compared to the conventional.
