Description
본 발명은 스피커의 진동판을 두께가 얇고 가벼운 필름을 이용 원통형으로 구성하여 음량 재생효율을 높이고 조립 및 제작을 용이하게 한 원통형 진동판 스피커에 관한 것이다.The present invention relates to a cylindrical diaphragm speaker configured to form a cylindrical diaphragm using a thin and light film to increase volume reproduction efficiency and to facilitate assembly and fabrication.
종래 스피커는 원추형 진동판이나 돔형 진동판을 영구자석으로 구성된 자기회로 자장내에 설치된 음성코일에 부착시켜 이에 음성전류가 흐르면 진동하여 소리가 발생되게 구성하였던 것이어서 진동판의 각 부품을 접착제로 접착 고정하는 공정이 복잡할 뿐 아니라 정교성과 정밀도가 유지 되어야 하며 작업 인원의 증가로 생산원가의 상승원인이 되었고 접착제의 과다사용으로 스피커 진동부분의 중량이 증가되어 음색음향 등의 성능이 저하되는 등의 문제점이 있었다.Conventional speaker is a conical diaphragm or dome diaphragm attached to the voice coil installed in the magnetic circuit magnetic field consisting of permanent magnets, so that when the voice current flows it vibrates to generate sound, the process of adhesively fixing each part of the diaphragm with an adhesive is complicated. In addition, the sophistication and precision must be maintained, and the increase in the number of workers has led to an increase in production cost, and due to the excessive use of adhesives, the weight of the vibration part of the speaker is increased, resulting in deterioration of performance such as tone sound.
또한 원추형 또는 돔형 진동판은 진동판의 구조적 특성에 따라 분할공진이 발생하고 혼변조가 생기는 등의 문제점이 있었다.In addition, the conical or dome type diaphragm has problems such as split resonance and intermodulation depending on the structural characteristics of the diaphragm.
본 발명은 전기한 바와 같은 문제점을 제거코자 고안한 것으로서,The present invention has been devised to eliminate the above problems,
진동판을 얇고 연질의 필름으로 원통형 또는 반원통형으로 진동판을 구성하여 분할공진 및 혼 변조가 발생되지 않게 하여 음량재생효율을 높이고 조립 및 제작을 용이하게 하여 생산성 향상 및 생산원가의 절감을 도모하기 위한 것이다.The diaphragm is made of thin and soft film to form cylindrical or semi-cylindrical diaphragm to prevent split resonance and horn modulation so as to improve the volume reproduction efficiency, facilitate assembly and fabrication, and improve productivity and reduce production cost. .

스피커에 있어서,In the speaker,
보이스코일 보빈(1) 상부외측주변과 고정틀(2)에 유연한 재질의 와셔형 댐퍼(3)를 접착시키고,Bond the washer-type damper (3) of flexible material to the upper outer periphery of the voice coil bobbin (1) and the fixing frame (2),
이 댐퍼(3)의 상부 중앙에 가볍고 긴 고정대(4)를 길이 방향으로 접착 고정하여 두께가 얇고 가벼운 필름 진동판(5)(5')을 원통형으로 구부려 일측은 고정대(4)의 양쪽면에 접착고정하고 타측은 외측 고정틀(6)에 접착 고정하되,The light and long fixing stand 4 is fixed to the upper center of the damper 3 in the longitudinal direction to bend the thin and light film diaphragm 5 and 5 'into a cylindrical shape, and one side is attached to both sides of the fixing stand 4. Fixing and fixing the other side to the outer fixing frame (6),
필름 진동판(5)(5') 중앙부위에 좁고 긴 접착테이프(7)(7')를 길이 방향으로 부착하며 외측 고정틀(6) 중앙부위에 틈새(8)(8')를 형성되게 한 것이다.Narrow and long adhesive tapes (7) (7 ') are attached to the center of the film diaphragm (5) (5') in the longitudinal direction and a gap (8) (8 ') is formed in the center of the outer fixing frame (6). .
미설명 부호 9는 영구자석, 10은 폴피스이다.Reference numeral 9 is a permanent magnet, 10 is a pole piece.
이와 같은 본 발명의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention in detail as follows.
본 발명의 제작과정을 보면Looking at the manufacturing process of the present invention
먼저 보이스코일보빈(1)을 수직 운동시키기 위하여 유연한 재질의 와셔형 댐퍼(3)를 보이스코일보빈(1) 상부 외측 주변과 고정틀(2)에 접착시키고 이 댐퍼(3)의 상부 중앙에 가볍고 긴 고정대(4)를 길이 방향으로 진동판(5)(5')의 폭만큼 접착 고정시킨다.First, in order to vertically move the voice coil bobbin (1), a washer-type damper (3) made of a flexible material is bonded to the outer periphery of the upper part of the voice coil bobbin (1) and the fixing frame (2), and is light and long in the upper center of the damper (3). The fixing table 4 is adhesively fixed by the width of the diaphragms 5 and 5 'in the longitudinal direction.
이에 두께가 얇고 연질인 필름을 재료로 진동판(5)(5')를 반원통형 또는 원통형으로 형성하여 진동판(5)(5')의 일측은 상기 고정대(4)의 양쪽면에 접착 고정시키고 진동판(5)(5')의 중앙부위에 좁고 긴 접착테이프(7)(7')를 부친 후 진동판(5)(5')의 타측을 외측 고정틀(6)에 접착 고정시키므로 본 발명이 완성되는 것이다.Accordingly, the diaphragm 5, 5 ′ is formed into a semi-cylindrical or cylindrical shape by using a thin, soft film as a material. One side of the diaphragm 5, 5 ′ is adhesively fixed to both sides of the holder 4, and the diaphragm is formed. (5) After attaching the narrow and long adhesive tape (7) (7 ') to the central portion of the center portion of the diaphragm (5) (5') is fixed to the outer fixing frame (6), the present invention is completed will be.
여기서 진동판(5)(5')에 접착테이프(7)(7')를 부착하는 것은 진동판(5)(5')의 진동시 발생되는 분할 공진을 방지하기 위한 것이다.Attaching the adhesive tapes 7 and 7 ′ to the diaphragm 5 and 5 ′ is intended to prevent split resonance occurring when the diaphragm 5 and 5 ′ are vibrated.
이와 같이 제작된 본 발명의 스피커에 음성전류가 흐르면 보이스코일보빈(1)이 진동하고 이 진동이 댐퍼(3)의 고정대(4)에 전달되고 이 고정대(4)에 부착된 두께가 얇고 가벼운 필름재의 진동판(5)(5')에 진동이 전달되어 주변 공기를 진동시켜 소리를 재생시키는 것이다.The voice coil bobbin 1 vibrates when a voice current flows through the speaker of the present invention manufactured as described above, and the vibration is transmitted to the holder 4 of the damper 3, and the thin and light film attached to the holder 4 is thin. Vibration is transmitted to the vibration plates 5 and 5 'of the ash to vibrate the surrounding air to reproduce sound.
소리의 재생시 발생되는 정재파의 발생을 방지하고 억제하기 위해 고정틀 중앙 부위에 적절한 크기와 길이의 틈새(8)(8')를 형성하였다.In order to prevent and suppress the generation of standing waves generated during sound reproduction, gaps 8 and 8 'of appropriate size and length were formed in the center of the fixing frame.
이상과 같은 본 발명은 종래의 원추형 진동판이나 돔형 진동판과는 다른 구조인 반원통형 또는 원통형으로 진동판을 형성한 것으로 그 구조가 간단하고 생산성이 우수하며 특수재질이나 초정밀 가공이 필요치 않고 노동력의 감소로 제조원가를 절감할 수 있으며 원통형, 반원통형의 진동판 구조로 넓은 지향 특성과 고충실도 음향재생이 가능하며 진동판에서의 분할 공진 및 혼변조가 발생치 않아 음향재생 효율을 높일 수 있는 등의 효과가 있는 것이다.The present invention as described above is a diaphragm formed in a semi-cylindrical or cylindrical, which is a structure different from the conventional conical diaphragm or dome diaphragm, its structure is simple and excellent in productivity, and does not require special materials or ultra-precision processing, and reduces manufacturing costs. Cylindrical and semi-cylindrical diaphragm structure can reduce the size, wide directional characteristics and high fidelity sound reproduction, and can improve the sound regeneration efficiency because there is no split resonance and intermodulation in the diaphragm.
