본 고안은 이중 진동판 스피커(DOUBLE CONE SPEAKER)에 있어서, 보조 진동판(SUB CONE)에 원추체를 형성시켜 고음특성을 개선시킨 개량된 이중 진동판스피커에 관한 것이다.The present invention relates to an improved dual diaphragm speaker in a double diaphragm speaker (DOUBLE CONE SPEAKER), in which a conical body is formed in an auxiliary diaphragm (SUB CONE) to improve high-pitched characteristics.
익히 아는 바와 같이 스피커는 자계 B(T) 내부에 있는 길이 L(M)인 도체에 전류 I(A)를 흘리면 도체는 전류와 자계면에 직각방향으로 힘이 작용하는 플레밍의 왼손법칙을 적용한 것으로써, 일정한 자계의 내부에 보이스코일을 직각으로 설치하고 여기에 음성전류를 흘리면그 전류에 비례하여 보이스코일이 상하운동하고 진동판과 공기의 압력변화로 인한 음이 발생하게 되는 것이다.As you know, the speaker applies the current I (A) to the conductor of length L (M) inside the magnetic field B (T), and the conductor applies Fleming's left hand law, which acts at right angles to the current and the magnetic surface. For example, if a voice coil is installed at a right angle inside a certain magnetic field and a negative current flows therein, the voice coil moves up and down in proportion to the current, and a sound is generated by a change in pressure of the diaphragm and air.
한편, 일반적으로 사용되고 있는 싱글 콘(SINGLE CONE) 스피커의 진동판(CONE)에서는 고음역에서의 찌그러짐 증가현상이 나타나기 때문에 이를 해결하고자 진동판의 안쪽에 보조진동판(SUB CONE)을 설치한, 소위 이중 진동판 스피커가 개발되어 사용되는 바 보이스코일이 감겨진 보빈과 진동판의 접합부에 상기 진동판보다 작은 각도로 벌어진 고음전용의 보조진동판을 붙인 것이다.On the other hand, in the diaphragm (CONE) of a single cone speaker, which is generally used, an increase in distortion in the high range appears, so that a so-called double diaphragm speaker installed with a sub vibration plate (SUB CONE) inside the diaphragm to solve this problem The developed and used bar voice coil is attached to the junction of the bobbin and the diaphragm wound with a subsidiary vibration plate dedicated for high sound at an angle smaller than that of the diaphragm.
그런데, 보조 진동판(SUB CONE)에 반사되는 반사음이 상호 간섭되어 특정한 위치에서는 음과의 산과 산, 골과 골이 겹치게 되므로 파상음이 발생하게 된다.However, the reflected sound reflected on the sub diaphragm (SUB CONE) is mutually interfering, so that the peaks and peaks, valleys and valleys of the yin and yang overlap at a specific position, so that a wavy sound is generated.
이에 본 고안은 상기와 같은 종래의 문제점을 해소하기 위해서 보조 진동판(SUB CONE) 내측에 원추체를 형성시켜 음의 반사를 적절히 조절하도록 보조 진동판의 경사각을 형성시켜 줌으로써 산과 산, 골과 골에 동시에 발생되지 않게 하기 위한 것이다.In order to solve the above problems, the present invention forms a cone inside the sub diaphragm, and simultaneously forms the inclination angle of the sub diaphragm to appropriately adjust the negative reflection, so that the acid and the mountain, the bone and the bone are simultaneously generated. It is to prevent it from becoming.
이하 첨부도면을 참고하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 포올(1)(POLE)과 마그네트(2)(MAGNET) 및 프레임(3)(FRAME)에 지지된 진동판(4)(CONE)과 보조진동판(5)(SUB CONE)으로 이루어진 이중 진동판 스피커에 있어서, 상기 보조진동판(5)에 다수의 원추체(7)를 등간격으로 형성시켜 완성된 이중 진동판 스피커이다.The present invention is a dual diaphragm consisting of a diaphragm 4 (CONE) and an auxiliary vibrating plate 5 (SUB CONE) supported on a pole (1) (POLE), a magnet (2) (MAGNET) and a frame (3) (FRAME). The speaker is a double diaphragm speaker formed by forming a plurality of cones 7 at equal intervals on the auxiliary vibration plate 5.
즉, 보조진동판(5)의 내부에 제2도에서와 같이 다수개의 원추체(7)를 형성시켜 둔 것으로서 이들은 등간격으로 배치되어진 구조를 이룬다. 따라서, 보조진동판내에서 발생하는 직접음과 간점음과의 간섭현상이 고르게 분포되어 불연속적인 파상음을 제거시켜주므로 고음특성이 향상됨은 물론 원음의 재현을 실현시킬 수 있는 효과가 있다.That is, as shown in FIG. 2, a plurality of cones 7 are formed inside the auxiliary vibration plate 5, and they form a structure arranged at equal intervals. Therefore, the interference between the direct sound and the point sound generated in the auxiliary vibrating plate is distributed evenly, thereby eliminating discontinuous wave sounds, thereby improving high-pitched characteristics and realizing the reproduction of the original sound.
