Abstract
Description
따라서 본 발명 스피커의 실시 예를 설명하면 다음과 같다.
일반적으로 정상적인 소리가 형성되려면 표1에서 보는 것 같아 완전한 파형이 형성되어야 한다.
즉 A에서 B까지의 좌형은 스피커(1)의 뒷면에서 발생되는 후면 발생음을 표현한 것이고, B에서 C까지의 곡선은 스피커(1)의 전면 발생음을 표현한 것이다.
[표 1]
또한 표 2는 전면 진동판의 위상을 보면 D에서 E까지는 진동판이 최전면에서 최후면으로 가는 것을 표시하였다.
[표 2]
이때는 전면에서는 공기에 충격을 주지 않으므로 전면 발생음이 나지 않으뒤쪽, 진동판(4) 후면에서는 G에서 H까지 진행하며 뒤쪽 공기를 충격하므로 후면 발생음이 진동판(4)을 중심으로 뒤쪽으로 진행하는 소리가 발생된다.
이와 반대로 E에서 F까지는 진동판(4)의 전면이 앞쪽의 공기에 충격을 가하여 진동판(4)의 전면에서 소리가 발생하여 앞쪽으로 진행하고 진동판(4)의 후면에서는 H에서 I까지 처럼 최후면에서 최전면으로 진행하기 때문에 진동판(4)의 후면의 공기의 충격을 주지 못 하므로 후면에서는 소리가 발생하지 않는다.
표 2의 설명을 그림으로 표시하면 표 3처럼 된다.
[표 3]
◈ K는 전면 발생음
◈ J는 후면 발생음
◈ L은 전후면에서 소리 나지 않는 부분이다.
표 4는 보는 바와 같이 E에서 F까지와 G에서 H까지가 합쳐져서 완전한 좌형을 형성하는 결과이다.
[표 4]
표 5는 후면 발생음이 유도커버(2)에 반사되어 전면부로 보내는 현상을 그린 그림이다.
[표 5]
따라서 본 발명의 명세서에서 음역대는 스피커(1)의 진동판(4)이 최전면에서 최후면으로 가는 동안을 발하는 표시 " " 에 해당하며, 양역대라 함음 진동판(4)이 최후면에서 최전면으로 진행하면 전면 발생음을 발생시키는 표시 " "를 말한다.
[표 6]
표 6은 현장음을 구현하는 스피커(1)의 작동 예이며, 가운데에서는 전면 발생음 영역이며, 테두리의 부분은 후면 발생음이 반사 유도되어 나오는 공간이다.
[표 7]
표 7은 후면 발생음 영역과 전면 발생음 영역이 합하여 표 1과 같은 완전한 좌형을 형성하여 마이크로 들어가는 소리를 들을 수 있으며, 일반적인 스피커에서는 앞소리와 뒷소리가 어울리지 못하고 따로 다른 방향에서 움직이므로 서로 어울리지 못하여 명료도가 떨어지고 듣는이가 짜증나는 결과로 다가온다.
Claims (3)
- 전면부터 진동판, 댐퍼, 리드 와이어가 순차적으로 위치하여 진동판과 간격을 형성한 상태로 진동판을 감싸는 프레임과 상기 프레임 중앙에는 통공되어 진동 코일, 요크, 마그네트 등으로 구성되어 있으며, 프레임 외주 일측단에는 진동 코일과 접속되며 외부 접속단자와 접속되도록 된 접속부가 마련된 스피커에 있어서,상기 진동판을 감싸는 프레임의 외주면 중앙에 부착되어 간격을 형성한 상태로 전면으로 감싸지게 포개져 진동판의 후면으로 발생되는 후면발생음을 스피커의 전면으로 유도 반사하여 전면발생음과 동시에 출력할 수 있도록 개구부가 형성된 유도커버가 부착된 것을 특징으로 하는 현장음을 구현하는 스피커.
- 제 1항에 있어서,상기 진동판의 후면에 프레임을 대체하여 감싸지도록 유도커버가 부착된 것을 특징으로 하는 현장음을 구현하는 스피커.
- 제 1항에 있어서,고음역 스피커에 있어서, 마그네트 후면에는 유도돌기가 일체로 형성된 반구형 유도커버가 긴밀하게 위치한 것을 특징으로 하는 현장음을 구현하는 스피커.
