본 발명은 콘덴서 마이크로폰 카트리지에 관한 것이다.The present invention relates to a condenser microphone cartridge.
마이크나 전화기, 테이프레코오더, 장난감등에 부착하여 음파를 전기적 신호로 변화시키는데 사용되는 콘덴서 마이크로폰 카트리지는 제 2 도에 도시된 바와 같은 구조의 것이 공지되어 있다. 즉, 이를 살펴보면, 하측 중앙에 통공(1)이 형성되어 그외부에 커버(2)가 부착된 케이스(3)의 내부에 극링(4)과 진동막(5)이 접착되어 있고, 그 상부에 고정전극(6)과 절연체(7)가 높여지며, 다시 그 상측으로 금속단자판(8)이 재치되어 그 일측에 증폭소자(9)의 입력선(10)이 접속되고, 상기 증폭소자(9)는 출력선(11)이 회로기판(12)에 납땜(13)으로 접속된 구조로 되어있다.Condenser microphone cartridges, which are used to attach a microphone, a telephone, a tape recorder, a toy, and the like to convert sound waves into electrical signals, are known to have a structure as shown in FIG. That is, looking at this, the through hole (1) is formed in the lower center and the pole ring (4) and the vibrating membrane (5) is bonded to the inside of the case (3) to which the cover (2) is attached to the outside, and the upper part The fixed electrode 6 and the insulator 7 are raised, and the metal terminal plate 8 is placed on the upper side thereof, and the input line 10 of the amplifying element 9 is connected to one side thereof, and the amplifying element 9 is provided. Has a structure in which the output line 11 is connected to the circuit board 12 by soldering 13.
그러나 이와 같은 종래의 콘덴서 마이크로폰 카트리지는 그 구성부품으로서, 유전체가 도포된 진동막(5)의 상측에 고정전극(6)과 금속단자판(8)이 연속하여 접속하고 있고, 고정전극의 절연을 위하여 원통형의 절연체(7)가 필요하게 되어 전반적으로 고가인 다수의 부품이 조립됨으로 인하여 제품의 크기가 커지고, 조립 공정이 복잡해지며 성능이 저하되는 문제가 있다.However, such a conventional condenser microphone cartridge is a component thereof, and the fixed electrode 6 and the metal terminal plate 8 are continuously connected to the upper side of the vibrating membrane 5 coated with a dielectric material. Cylindrical insulator 7 is required, and as a result, assembling a large number of expensive parts, the size of the product increases, the assembly process is complicated, and performance is degraded.
본 발명은 이와 같은 종래의 콘덴서 마이크로폰 카트리지의 문제점을 해소하기 위하여 연구된 것으로서 진동막의 상측에 증폭소자의 입력단자와 접속되어 절연링으로 절연된 고정전극을 재치하고, 그 상측에 정전기 물질이 도포된 유전체판을 재치함으로써, 종래와 같이 고가인 다수의 부품을 사용하지 않고도 일관된 공정으로 제반부품을 자동으로 조립시킬 수 있게 하여 제품원가를 줄이고, 성능이 보다 향상된 제품을 박형화시켜 제조할 수 있도록 한 것이다.The present invention has been studied to solve the problems of the conventional condenser microphone cartridge, and the fixed electrode connected to the input terminal of the amplifying element on the upper side of the vibration membrane and insulated by an insulating ring, and the electrostatic material is coated on the upper side By mounting the dielectric plate, it is possible to automatically assemble all the components in a consistent process without using many expensive components as in the past, thereby reducing product cost and manufacturing thinner products with improved performance. .
이하 본 발명을 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제 1 도는 본 발명의 콘덴서 마이크로폰 카트리지의 단면도로서, 하측중앙에 통공(1)이 형성되어 그외부에 커버(2)가 부착된 케이스(3)의 내부에 극링(4)과 진동막(5)이 재치되고, 증폭소자(9)가 회로기판(12)에 납땜(13)으로 고정된 콘덴서 마이크로폰 카트리지에 있어서, 상기 진동막(5)의 상부에 증폭소자(9)의 입력단자(10)와 접속되어 절연링(17)으로 절연된 고정전극(16)을 재치하고, 다시 그 상측에 정전기 물질이 도포된 유전체판(20)을 설치하며, 상기 고정전극(16)의 외주연에 수개의 통공(21)을 형성하여서 된 구조이다.1 is a cross-sectional view of the condenser microphone cartridge of the present invention, in which a through hole 1 is formed at a lower center thereof, and a polar ring 4 and a vibrating membrane 5 are formed inside a case 3 having a cover 2 attached thereto. In this condenser microphone cartridge, in which the amplifying element 9 is fixed to the circuit board 12 by soldering 13, the input terminal 10 of the amplifying element 9 and the input terminal 10 of the amplifying element 9 The fixed electrode 16 connected and insulated by the insulating ring 17 is placed, and a dielectric plate 20 coated with an electrostatic substance is installed on the upper side thereof, and several through holes are formed in the outer circumference of the fixed electrode 16. It is a structure formed by forming (21).
이와 같이 구성된 본 발명의 콘덴서 마이크로폰 카트리지는 절연링(17)에 의하여 케이스(3)와 절연된 고정전극(16)이 진동막(5)과 바로 접속된 상태에서 고정전극(16)의 상부에 유전체판(20)이 별도로 접착되어 있기 때문에 종래에 비하여 진동막(5)을 보다 얇게 구성할 수 있어 주파수특성을 향상시킬 수 있는 잇점이 있고, 동시에 유전체판(20)을 진동막(5)과 별도로 구성하므로 유전체판(20)의 두께를 보다 크게 할 수 있어 정전기 보유능력을 크게 함으로써 콘덴서 마이크로폰의 성능을 현저히 향상시킬 수 있는 효과가 있다.The condenser microphone cartridge of the present invention configured as described above has a dielectric on top of the fixed electrode 16 in a state in which the fixed electrode 16 insulated from the case 3 by the insulating ring 17 is directly connected to the vibrating membrane 5. Since the plate 20 is separately bonded, the vibrating membrane 5 can be made thinner than the conventional one, and thus the frequency characteristic can be improved, and at the same time, the dielectric plate 20 is separated from the vibrating membrane 5 separately. As a result, the thickness of the dielectric plate 20 can be made larger, and thus the performance of the condenser microphone can be remarkably improved by increasing the electrostatic capacity.
뿐만 아니라 본 발명의 콘덴서 마이크로폰 카트리지는 고정전극(16)의 외주연에 수개의 통공(21)이 형성되어 있어 지향성 및 주파수 특성을 조절할 수 있는 특징이 있다.In addition, the condenser microphone cartridge of the present invention is characterized in that the through holes 21 are formed on the outer circumference of the fixed electrode 16 to adjust the directivity and frequency characteristics.
이와 같이 본 발명의 콘덴서 마이크로폰 카트리지는 그 내부구조를 개선함으로써, 부품수를 줄이고 제조공정을 단축하여 생산원가를 절감시킬 수 있을 뿐만 아니라, 성능이 우수한 제품을 보다 박형으로 제조할 수 있는 효과가 있는 신규한 발명이다.As described above, the condenser microphone cartridge of the present invention improves its internal structure, thereby reducing the number of parts and shortening the manufacturing process, thereby reducing the production cost, and having the effect of making thinner products with better performance. It is a novel invention.
