(산업상의 이용분야)(Industrial use)
본 고안은 압전소자의 상하면에 진동판이 이중으로 설치된 압전스피커에 관한 것으로, 특히 상하 진동판사이에 댐퍼를 설치해서 음질의 개선을 도모한 이중진동판구조의 압전스피커에 관한 것이다.The present invention relates to a piezoelectric speaker provided with double diaphragms on the upper and lower surfaces of the piezoelectric element, and more particularly, to a piezoelectric speaker having a double vibrating plate structure that improves sound quality by providing a damper between upper and lower diaphragms.
(종래의 기술 및 그 문제점)(Prior art and its problems)
일반적으로 압전스피커는 자기물질의 결정에 기계적인 힘을 가하면 대전현상이 나타나는 한펀 그 결정을 전계속에 놓으면 기계적으로 찌그러지는 현상이 나타나는 압전소자에다 전압을 가하여 기계적 변형의 일종인 진동이 일어나도록하고, 이 진동을 진동판에 전달하여 음압을 발생시키도록 된 스피커로서, 종래에는 압전소자의 일면에 진동판의 일단부가 부착됨과 동시에 그 진동판의 타단부가 다시 프레임에 연결된 구조로 되어 있다.In general, a piezoelectric speaker applies a mechanical force to a crystal of a magnetic material, and when a crystal is placed on the front of the crystal, a voltage is applied to the piezoelectric element, which causes mechanical distortion. The speaker is configured to transmit the vibration to the diaphragm to generate a sound pressure. In the related art, one end of the diaphragm is attached to one surface of the piezoelectric element and the other end of the diaphragm is connected to the frame again.
그리나 이와 같은 구조로 된 압전스피커에 있어서는 그 진동특성상 청취감이 좋은 중, 저음을 발생시키지 못하기 때문에 고음전용 스피커나 신호용 부조등에만 사용해야 되는 제한이 따르게 되고, 특히 고음스피커에서는 압전소자 특유의 금속성 재생음이 발생되는 등의 문제점이 있었다.However, in the piezoelectric speaker having such a structure, the vibration characteristics of the piezoelectric speaker have a good listening feeling, and they do not generate low sound. Therefore, the piezoelectric speaker has limitations that should be used only for high-pitched speakers and signal relief. There was a problem that a playback sound is generated.
(고안의 목적)(Purpose of designation)
이에, 본 고안은 상기한 사정을 감안해서 안출된 것으로, 청취감이 좋은 중, 저음을 발생시킬 수 있게 됨과 더블어, 압전소자 특유의 금속성 재생음이 제거되어 음질의 향상을 도모할 수 있도록 된 압전스피커를 제공함에 그 목적이 있다.Accordingly, the present invention has been devised in view of the above-described circumstances, and the piezoelectric speaker is capable of generating low sound while having a good listening feeling, and removing the metallic reproduction sound peculiar to the piezoelectric element to improve the sound quality. The purpose is to provide.
(고안의 구성)(Composition)
상기 목적을 실현하기 위한 본 고안에 따른 압전스피커는 압전소자의 상, 하 양면에 진동판이 부착되어 있는 압전스피커에 있어서, 상기 상, 하진동판의 사이에 압전소자와 프레임에 접속되는 댐퍼가 설치된 구조로 되어있다.A piezoelectric speaker according to the present invention for realizing the above object is a piezoelectric speaker having a vibration plate attached to both the upper and lower surfaces of the piezoelectric element, a structure in which a damper is connected to the piezoelectric element and the frame between the upper and lower vibration plates. It is.
(작용)(Action)
상기한 구성으로 된 본 고안에 따른 압전스피커에 의하면, 이중구조의 진동판사이에 댐퍼가 설치됨으로써 청취감이 양호한 중, 저음영역이 확장됨과 더블어, 압전소자 특유의 금속성 재생음이 제거되게 된다.According to the piezoelectric speaker according to the present invention having the above-described configuration, the damper is provided between the diaphragm of the dual structure, the middle of the bass region is extended, and the double tone, the metallic reproduction sound peculiar to the piezoelectric element is removed.
[실시예]EXAMPLE
이하, 도면을 참조해서 본 고안의 실시예를 상세히 실명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
제1도는 본 고안에 따른 압전스피커(1)를 도시해 놓은 도면이고, 제2도는 그 단면도로서, 도면에 도시된바와 같이 본 고안에 따른 압전스피커는 압전소자(2)의 상하양면에 진동판(3)이 각각 부착설치되고, 이 상하진동판(3)의 사이에 상기 압전소자(2)와 프레임(4)에 접속되는 댐퍼(5)가 설치된 구조로 되어 있다.1 is a view showing a piezoelectric speaker 1 according to the present invention, Figure 2 is a cross-sectional view, as shown in the drawing, the piezoelectric speaker according to the present invention is a diaphragm (top and bottom surfaces of the piezoelectric element 2) ( 3) are attached to each other, and the damper 5 connected to the piezoelectric element 2 and the frame 4 is provided between the upper and lower vibration plates 3, respectively.
상기한 구조에 있어서는 상기 댐퍼(5)가 압전소자(2)의 진동을 제한하게 된다. 즉, 압전소자(2)의 진동주파수를 낮추게 된다. 따라서 종래의 압전스피커와 같이 압전소자(2)의 불필요한 고주파 진동이 진동판(3)에 전달되어 특유의 금속성 재생음이 발생되는 것이 방지됨과 더블어, 청취감이 좋은 중, 저음영역이 확장되게 된다.In the above structure, the damper 5 limits the vibration of the piezoelectric element 2. That is, the vibration frequency of the piezoelectric element 2 is lowered. Therefore, as in the conventional piezoelectric speaker, unnecessary high frequency vibration of the piezoelectric element 2 is transmitted to the diaphragm 3 to prevent the generation of a unique metallic reproduction sound, and double, the middle of the bass region with a good listening feeling is expanded.
즉, 댐퍼(5)로 압전소자(2)고유의 진동특성을 재생시킴으로서 출력음압특성을 향상시킬 수 있게된다.That is, the output sound pressure characteristic can be improved by reproducing the vibration characteristic peculiar to the piezoelectric element 2 with the damper 5.
(고안의 효과)(Effect of design)
이상 설명한 바와 같이 본 고안에 의하면, 청취감이 양호한 중, 정음이 확장됨과 더블어, 압전소자 특유의 금속성 재생음이 제거된 압전스피커를 실현할 수 있게 된다.As described above, according to the present invention, it is possible to realize a piezoelectric speaker in which the quietness is expanded, and the double tone and the metallic reproduction sound peculiar to the piezoelectric element are removed while the listening feeling is good.
