摘要:
本发明涉及平板扬声器,尤其涉及通过多层音圈薄膜的阻抗控制,可增大感应电动势的具有多层PCB图形音圈薄膜的平板扬声器。根据本发明的具有多层PCB图形音圈薄膜的平板扬声器,将音圈进行PCB(Printed Circuit Board)图形印刷,并包含由4层以上的偶数层层压的音圈薄膜,所述音圈薄膜按2层相互串联连接,串联连接的音圈薄膜相互并联连接。
摘要(英):
The present invention relates to a flat-panel speaker, and more particularly, to a flat-panel speaker having a multilayer PCB pattern voice coil film, which enables induced electromotive force to be increased by controlling the impedance of the multilayer voice coil film. The flat-panel speaker having the multilayer PCB pattern voice coil film according to the present invention is characterized in that the voice coil comprises: a PCB (printed circuit board) pattern printed thereon and voice coil films stacked in an even number of 4 layers or more. Two layers each of said voice coil films are mutually connected in series, and the serially-connected voice coil films are connected to each other in parallel.
