The voice coil 23 that drives the upper diaphragm 21 to vibrate and sound, the upper diaphragm 21 is used to vibrate and sound, and the lower diaphragm 22 is used to strengthen the vibration of the upper diaphragm 21, and can prevent the polarization of the upper diaphragm 21, which can improve the acoustics of the speaker performance.

请参照图2以及图5，本实施例中的上振膜21包括第一振膜211和第二振膜212，第一振膜211和第二振膜212位于磁路***3相对的两侧，第一振膜211和第二振膜212分别固定于磁路***3和盆架11远离下振膜22的一端上，第一振膜211和第二振膜212位于磁路***3和盆架11之间，在壳体1的收容空间内，音圈23只占据部分空间，磁路***3与音圈23大小相近，从而在本实施例中，音圈23和磁路***3只占据第一振膜211和第二振膜212中间的部分空间，而与第一振膜211和第二振膜212相对的部分空间可以用于放置柔性电路板4，且具有足够的空间用于设计柔性电路板4的形状，而且可以适当增大下振膜22的面积以防止上振膜21的摇摆，从而改善扬声器的失真。Referring to FIG. 2 and FIG. 5 , the upper diaphragm 21 in this embodiment includes a first diaphragm 211 and a second diaphragm 212 , and the first diaphragm 211 and the second diaphragm 212 are located on opposite sides of the magnetic circuit system 3 . , the first vibrating membrane 211 and the second vibrating membrane 212 are respectively fixed on the magnetic circuit system 3 and the end of the basin frame 11 away from the lower vibrating membrane 22, and the first vibrating membrane 211 and the second vibrating membrane 212 are located in the magnetic circuit system 3 and the basin. Between the racks 11, in the housing space of the housing 1, the voice coil 23 only occupies part of the space, and the magnetic circuit system 3 and the voice coil 23 are similar in size, so in this embodiment, the voice coil 23 and the magnetic circuit system 3 only occupy Part of the space between the first diaphragm 211 and the second diaphragm 212, and the part of the space opposite to the first diaphragm 211 and the second diaphragm 212 can be used to place the flexible circuit board 4, and there is enough space for design The shape of the flexible circuit board 4 and the area of the lower diaphragm 22 can be appropriately increased to prevent the upper diaphragm 21 from swaying, thereby improving the distortion of the speaker.

请参照图2-图4，本实施例中的柔性电路板4设置在上振膜21与下振膜22之间，通过柔性电路板4可替换导线将音圈23通电，具体地，柔性电路板4包括与盆架11连接的第一连接边41、与音圈23连接的第二连接边42以及连接第一连接边41和第二连接边42的弹力臂43，在相关技术中，由于音圈23以及磁路***3占据了收容空间的大部分空间，从而无足够的空间用于避让弹力臂43，从而使弹力臂43设置在上振膜21和下振膜22正对形成的空间内，致使弹力臂43与下振膜22在弹力臂43朝向上振膜21的方向上相互重叠，从而使弹力臂43造成对下振膜22振动的干涉，使扬声器出现了纯音问题，本实施例中的弹力臂43在弹力臂43朝向上振膜21的方向上与上振膜21相对设置且与下振膜22错位设置。具体地，弹力臂43朝向上振膜21的方向指的是如图中的Z向，也是垂直于底盖12的方向。弹力臂43与上振膜21相对设置指的是在Z方向上，上振膜21与弹力臂43是具有重叠的，而弹力臂43与下振膜22错位设置指的是在Z方向上，弹力臂43与下振膜22不具有重叠的部分。本实施例中，由于弹力臂43与下振膜22在Z方向上不具有重叠的部分，因此弹力臂43不会干涉下振膜22的振动，因此不会造成扬声器的纯音问题，使扬声器的声学性能更佳。Referring to FIGS. 2-4 , the flexible circuit board 4 in this embodiment is disposed between the upper diaphragm 21 and the lower diaphragm 22, and the voice coil 23 is energized through the replaceable wires of the flexible circuit board 4. Specifically, the flexible circuit The plate 4 includes a first connecting edge 41 connected with the basin frame 11, a second connecting edge 42 connected with the voice coil 23, and an elastic arm 43 connecting the first connecting edge 41 and the second connecting edge 42. In the related art, due to the The voice coil 23 and the magnetic circuit system 3 occupy most of the storage space, so there is not enough space for avoiding the elastic arm 43, so that the elastic arm 43 is arranged in the space formed by the upper diaphragm 21 and the lower diaphragm 22 facing each other. In this case, the elastic arm 43 and the lower diaphragm 22 are caused to overlap each other in the direction of the elastic arm 43 toward the upper diaphragm 21, so that the elastic arm 43 interferes with the vibration of the lower diaphragm 22, and the speaker has a pure sound problem. In the example, the elastic arm 43 is disposed opposite to the upper vibrating membrane 21 in the direction in which the elastic arm 43 faces the upper vibrating membrane 21 , and is disposed at a dislocation from the lower vibrating membrane 22 . Specifically, the direction in which the elastic arm 43 faces the upper diaphragm 21 refers to the Z direction in the figure, which is also the direction perpendicular to the bottom cover 12 . The relative arrangement of the elastic arm 43 and the upper diaphragm 21 means that in the Z direction, the upper diaphragm 21 and the elastic arm 43 are overlapped, and the dislocation of the elastic arm 43 and the lower diaphragm 22 refers to the Z direction, The elastic arm 43 does not have an overlapping portion with the lower diaphragm 22 . In this embodiment, since the elastic arm 43 and the lower diaphragm 22 do not have overlapping parts in the Z direction, the elastic arm 43 will not interfere with the vibration of the lower diaphragm 22, so it will not cause the problem of pure sound of the speaker and make the speaker's Better acoustic performance.
