Double-sided multi-coil diaphragm loudspeaker

By employing a double-sided, multi-coil symmetrical wiring design on the planar diaphragm speaker, with 3-6 coils arranged in a clockwise-counterclockwise direction, signal enhancement and uniform diaphragm stress are achieved, thereby improving the speaker's sensitivity and sound quality.

Abstract

本发明公开了一种双面多线圈振膜喇叭，包括平面薄膜；平面薄膜的一面设有A面多线圈，平面薄膜的另一面设有与之匹配对应的B面多线圈，A面多线圈远离平面薄膜的一侧设有上支架，上支架中设有A磁铁组，B面多线圈远离平面薄膜的一侧设有下支架，下支架中设有与A磁铁组匹配对应的B磁铁组；A面多线圈上设有同圆心的A面平面线圈组，A面平面线圈组中设有M个依次导通电性连接的线圈，3≤M≤6，A面平面线圈组中相邻线圈之间设有线圈分隔间距，A面平面线圈组中相邻线圈的绕线方向相反；B面多线圈上设有与A面平面线圈组匹配对应的B面平面线圈组。本发明采用在膜片上进行对称双面多线圈线路重叠布线，提升振膜受力均匀性、灵敏度。
