Abstract

본 발명은 자기회로내의 보이스코일에 음성전류를 흘려 발생하는 자장에 의해 진동판을 진동시켜 음성을 재현하는 다이나믹형 스피커에 있어서, 그 보이스코일을 원통이 아닌 평면상에 외권시켜 납작하게 형성하여 제조를 용이하게 하면서도 용도에 따라 다양한 형태를 갖게한 보이스코일을 평면상으로 형성한 다이나믹형 스피커에 관한 것으로서, 종래 원통형 코일보빈과 그 주면에 감긴 보이스코일을 가짐으로해서 제작상 불편한 점이나 한정된 형태의 결점을 제거코자, 코일선을 평면적으로 와권시켜 그 양면에서 입착판으로 압착하여 평판상의 가동코일판을 형성시키고 이를 1조의 막대형 자기 회로판 사이에 이겨 삽입하고, 그 일축 또는 양측 끝단에 진동판을 부착시켜 구성하므로서 그 제작을 용이하게 하고 목적이나 용도에 따라 다양한 형태의 스피커를 제공되게 한 것이다.The present invention relates to a dynamic speaker which reproduces a voice by vibrating a diaphragm by a magnetic field generated by flowing a voice current in a voice coil in a magnetic circuit, wherein the voice coil is formed by flattening the outer coil on a flat surface instead of a cylinder. The present invention relates to a dynamic speaker in which a voice coil having a variety of shapes is formed in a flat shape in accordance with the intended use, and has a conventional cylindrical coil bobbin and a voice coil wound around its main surface. In order to remove the coil wires, the coil wires are wound in a flat manner and pressed on both sides of the coil plate to form a flat movable coil plate, which is inserted between a pair of rod-shaped magnetic circuit boards, and a vibration plate is attached to one end or both ends thereof. It is easy to manufacture by constructing and various forms according to purpose or use It would be provided by the speakers.
