5 : 사주면5: buy it

본 고안은 다수의 압전소자와 투명판을 이용하여 제작한 투명 스피커에 대한 것이다.The present invention relates to a transparent speaker manufactured using a plurality of piezoelectric elements and a transparent plate.

종래의 스피커는 제3도에서 보는 바와 같이 원형의 압전소자(13)하나를 후레임(11)내에 착설하는 진동판(14)에 부착시켜 제작하였다.The conventional speaker was manufactured by attaching one circular piezoelectric element 13 to the diaphragm 14 mounted in the frame 11, as shown in FIG.

그러나 이러한 스피커는 크기가 작은 원형의 압전소자 하나만 진동판에 부착시킨 것이기 때문에 음의 증폭능률이 좋지 못하고 저음 재생이 제대로 잘 되지 못하는 등의 결점이 있었다.However, such a speaker had only one small piezoelectric element of a small size attached to the diaphragm, so that the amplification efficiency of the sound was poor and the bass reproduction was not properly performed.

따라서 이런점을 해결하려면 스피커 자체를크게 제작해야 되므로 공간 면적을 많이 점유하게 되고, 특히 텔레비젼등과 같은 제품의 경우에는 제품의 규격상 소형 스피커를 부설하였지만 역시 제품의 일부분을 점유하게 되어 제품의 소형화와 다양한 디자인 개발에도 장애가 되는등의 페단도 있었다.Therefore, in order to solve this problem, the speaker itself needs to be made large, thus occupying a lot of space, and especially in the case of a product such as a TV, a small speaker is installed according to the specification of the product, but it also occupies a part of the product, thereby miniaturizing the product. There was also a pedan such as being an obstacle to the development of various designs.

본고안은 이와같은 점들을 해결하기 위해 원형의 압전소자 다수를 사각형상으로 되는 프레임의 세로 방향의 양측 내면에 일정간격으로 격리되게 부착하여 이들 사이에 진동판 역활을 하는 사각형상의 투명판을 일정 곡면이 유지되게 그 양측 단부를 압착시켜 스피커를 제작 하므로 진동판의 면적이 넓어져 음량이 증가되고 또 진동판 자체가 투명이기 때문에 텔레비젼의 경우에는 화면에, 액자의 경우에는 그 전면에 설치해도 되므로 스피커를 설치하기 위한 별도의 공간이 필요없게 되도록 고안한 것으로 첨부 도면에 의거 상술하면 다음과 같다.In order to solve these problems, the present invention attaches a large number of circular piezoelectric elements to the inner surfaces of both sides of the frame in a rectangular shape so as to be separated from each other at regular intervals. Since the speaker is manufactured by compressing both ends to maintain the volume of the diaphragm, the volume of the diaphragm is increased and the volume of the diaphragm itself is transparent. Therefore, the speaker may be installed on the screen in the case of a TV and in front of the frame in the case of a frame. It is designed to eliminate the need for a separate space as described above according to the accompanying drawings.

프레임(1)의 양측내면에 일정간격으로 격리되게 요입 형성한 수개의 결합홈(2)(2')에 수개의 원형 압전소자(3)(3')를 각각 일측부분이 끼워지게 결합 부착하고 비틀림 진동을 방지하기 위해 사주면(5)을 적정폭으로 절곡시킨 진동판용 투명판(4)을 음의 왜곡 현상을 방지하기 위해 일정곡면이 유지되게 그 양측 단부(4a)(4b)를 각 압전소자(3)(3')에 각각 접착시켜서 된 것이다.Several circular piezoelectric elements (3) (3 ') are coupled to one side of each of several coupling grooves (2) and (2') formed in a recess at regular intervals on both inner surfaces of the frame (1). The piezoelectric elements are disposed at both end portions 4a and 4b of the diaphragm transparent plate 4 having the inclined surface 5 bent to an appropriate width to prevent torsional vibration so that a constant curved surface is maintained to prevent negative distortion. (3) and (3 '), respectively.

미설명 부호 "6"은 텔레비젼이다.Reference numeral "6" is TV.

이와같이 구성되는 본고안은 진동판이 투명판(4)으로 되는 것이기 때문에 제2도에서와 같이 텔레비젼(6)의 경우에는 프레임(1)을 화면의 전면부에 설치해도 되며, 액자의 경우에는 액자의 전면부에 설치해도 되는 것으로 압전소자(3)(3')에 음성전압이 가해지면 프레임(1)의 세로면에 돌출된 결합부(2)(2')에 받쳐지게 부착된 이 압전소자(3)(3')의 진동막이 진동하게 되고 이에따라 투명판(4)이 공진을 일으켜 소리를 내게 되는 것이다.Since the diaphragm consists of a transparent plate 4 as described above, in the case of the television 6, the frame 1 may be provided at the front of the screen. The piezoelectric element (3) (3 ') may be provided on the front part. When a negative voltage is applied to the piezoelectric element (3) (3'), the piezoelectric element (2) (2 ') protruding from the vertical surface of the frame (1) is supported. 3) The vibrating membrane of 3 'vibrates, and thus the transparent plate 4 causes resonance and makes a sound.

따라서 본 고안은 텔레비젼의 경우 화면 전체로 부터 소리가 나오게 되는듯한 효과를 얻을 수 있어 생동감을 느낄 수 있게 됨은 물론 투명판(4)의 사주면(5)은 적정폭으로 절곡시켜 비틀림 진동을 방지하였고, 또 일정곡면이 유지되게 착설하므로 음의 왜곡면이 유지되게 착설하므로 음의 왜곡현상이 방지되며 면적도 넓어 음량이 증가되고 저음 재생능률이 향상된다.Therefore, the present invention can obtain the effect that the sound comes out from the whole screen in the case of the TV, and can feel the liveliness, as well as the inclined surface (5) of the transparent plate (4) to prevent the torsional vibration, In addition, the installation of a certain curved surface is maintained so that the distortion surface of the sound is maintained so that the distortion of the sound is prevented, the area is also wide, the volume is increased and the bass reproduction efficiency is improved.

또한 스피커를 별도로 제작할 필요가 없고, 그 두께가 얇아 실내공간을 점유하지 않게되며, 특히 텔레비젼의 경우에는 스피커의 설치 공간이 제거되므로 제품의 소형화나 다양한 디자인 개발에 매우 적합하며, 마그네트를 사용하지 않기 때문에 생산비도 절감되는 등 매우 실용적인 고안이다.In addition, the speaker does not need to be manufactured separately, and its thickness is thin so that it does not occupy the interior space. Especially, in the case of TV, the speaker installation space is eliminated, so it is very suitable for the miniaturization of products or the development of various designs. It is a very practical design because it also reduces production costs.
