도 1 및 도 2는 본 발명의 일 실시예에 따른 음향변환장치용 진동판을 제조하는 과정을 도시한 도면이다. 본 발명의 일 실시예에 따른 음향변환장치용 진동판은, 탄성력을 가지는 필름(100)으로 제조되며, 필름 재질은 PEEK나 우레탄, 또는 PEEK와 우레탄의 합지로 제조된다. 필름(100) 상에는 진동판에 부착되는 보이스 코일로 전기 신호를 인가하기 위해 전기 신호를 전달하는 통전 패턴(200)이 형성되어 있다. 또한, 보이스 코일의 인입선이 납땜되는 내부 납땜부(300) 및 터미널 등을 통해 전기 신호를 받아들이기 위한 외부 납땜부(400)도 필름(100) 상에 형성되어 있다. 1 and 2 are views illustrating a process of manufacturing a diaphragm for an acoustic transducer according to an embodiment of the present invention. The diaphragm for an acoustic transducer according to an embodiment of the present invention is made of a film 100 having elastic force, and the film material is made of PEEK or urethane, or a laminate of PEEK and urethane. On the film 100, an energization pattern 200 for transmitting an electrical signal is formed to apply an electrical signal to a voice coil attached to the diaphragm. In addition, an external soldering unit 400 for receiving an electrical signal through an internal soldering unit 300 and a terminal to which the lead wire of the voice coil is soldered is also formed on the film 100.
통전 패턴(200)과 내부 납땜부(300), 외부 납땜부(400)가 형성된 필름(100)을 진동판 금형(10) 상에 위치시키고 가압하여 진동판을 성형한다. 금형(10)은 진동판의 돔(110)을 형성하기 위해, 돔 형상의 돌출부(12)가 형성되어 있다. The diaphragm is formed by placing and pressing the film 100 on which the energization pattern 200, the internal soldering unit 300, and the external soldering unit 400 are formed on the diaphragm mold 10. In the mold 10, a dome-shaped protrusion 12 is formed to form the dome 110 of the diaphragm.
금형(10)에서 돔(110)이 성형된 다음, 필름(100)을 절단하여 진동판을 완성한다. After the dome 110 is molded in the mold 10, the film 100 is cut to complete the diaphragm.
도 3 및 도 4는 본 발명의 제1 실시예에 따른 음향변환장치용 진동판을 도시한 도면이다. 본 발명의 제1 실시예에 따른 음향변환장치용 진동판(1)은 진동판(1)의 외주를 따라 돌출된 돔(110)이 형성된다. 진동판(1)을 음향변환장치의 프레임에 안착할 수 있도록, 돔(110)은 진동판(1)의 최외곽에 형성되지는 않으며, 따라서 돔(110)의 외측에 안착부(120)가 구비된다. 또한 돔(110)의 내 측에도 필름으로 이루어진 내측부(130)가 존재한다. 3 and 4 are diagrams illustrating a diaphragm for an acoustic transducer according to a first embodiment of the present invention. In the diaphragm 1 for the acoustic transducer according to the first embodiment of the present invention, a dome 110 protruding along the outer circumference of the diaphragm 1 is formed. The dome 110 is not formed at the outermost side of the diaphragm 1 so that the diaphragm 1 can be seated on the frame of the acoustic transducer, and therefore, the seating part 120 is provided outside the dome 110. . In addition, there is an inner portion 130 made of a film on the inner side of the dome 110.
앞서 설명한 바와 같이, 진동판(1)에는 통전 패턴(200)이 일체로 성형되는데, 통전 패턴(200)은 돔(110)의 바깥측에서부터 돔(110)의 내부까지 연결되며, 보이스 코일로 전기적인 신호를 전달할 수 있도록 연결부(220)를 포함한다. 보이스 코일은 돔(110)의 내측부(130)에 부착되기 때문에, 프레임에 안착되는 안착부(120)로부터 내측부(130)까지 전기적인 신호를 전달할 수 있도록 형성되어야 한다. As described above, the conduction pattern 200 is integrally molded to the diaphragm 1, and the conduction pattern 200 is connected from the outside of the dome 110 to the inside of the dome 110 and electrically connected to the voice coil. It includes a connection unit 220 to transmit a signal. Since the voice coil is attached to the inner portion 130 of the dome 110, the voice coil should be formed to transmit an electrical signal from the mounting portion 120 mounted on the frame to the inner portion 130.
또한, 프레임 상에 형성되는 터미널 등과 납땜을 위한 외부 납땜부(400)가 돔(110)의 안착부(120)로부터 외부로 연장되어 형성된다. 외부 납땜부(400)는 전기적인 신호를 전달할 수 있는 통전 패턴이 진동판(1)을 형성하는 필름의 양 면에 모두 형성되고, 양 면에 형성된 통전 패턴을 땜납을 이용해 전기적으로 연결할 수 있도록 관통홀(410)이 형성된다. In addition, an external soldering portion 400 for soldering a terminal or the like formed on the frame is formed to extend outward from the seating portion 120 of the dome 110. The external soldering unit 400 has a conduction pattern capable of transmitting an electrical signal formed on both sides of the film forming the diaphragm 1, and through holes to electrically connect the conduction pattern formed on both sides with solder. 410 is formed.
또한 진동판(1)의 돔(110)의 내부에 위치하는 내측부(130) 내에는 보이스 코일의 인입선을 납땝하기 위한 내부 납땜부(300)가 형성된다. 통전 패턴(200)은 외부 납땜부(400)와 내부 납땜부(300)를 전기적으로 연결할 수 있도록 형성되며, 전기적인 신호가 간섭을 일으키기 않도록 서로 단락된 두 개 이상의 패턴이 구비된다. 바람직하게는 한 쌍의 내부 납땜부(300), 한 쌍의 외부 납땜부(400), 한 쌍의 통전 패턴(200) 구비된다. In addition, an inner soldering portion 300 for soldering the lead wire of the voice coil is formed in the inner portion 130 positioned inside the dome 110 of the diaphragm 1. The conduction pattern 200 is formed to electrically connect the external soldering unit 400 and the internal soldering unit 300, and two or more patterns are shorted to each other so that electrical signals do not cause interference.
