Abstract

一种有挡圈的音圈骨架,包括一个音圈骨架1,在音圈骨架的圆柱面上绕制线圈的位置边缘有至少一条环形的挡圈2。绕上线圈后,线圈的边缘与挡圈相靠在一起,在胶水变软时,挡圈起到阻挡的作用,能有效地防止线圈从音圈骨架上脱落下来,从而提高音圈的耐温性能,延长使用寿命。

Description

有挡圈的音圈骨架
本实用新型涉及一种扬声器音圈骨架的结构，一种有挡圈的音圈骨架。
音圈骨架是扬声器音圈的一个部件，在音圈骨架上绕上线圈后就成为音圈，音频信号电流在线圈中流过时，音圈受到磁场力的作用而振动，推动与之相连的音盆一起振动，发出声音。音圈骨架一般采用纸、工程塑料、铝等材料来制作。线圈采用耐热绝缘漆包线，用胶水粘在音圈骨架上。音圈工作时会发热。大功率的扬声器的音圈，在大功率输入下工作时，线圈在短时间内就会产生大量的焦耳热。粘结漆包线的胶水会因高温而软化甚至焦化，从而导致线圈的两端发生散圈的现象，或者整个线圈脱落。
本实用新型的目的是提出一种能防止音圈线圈脱落的音圈骨架的结构。
这种有挡圈的音圈骨架，包括一个音圈骨架，在音圈骨架的圆柱面上绕制线圈的位置边缘有至少一条环形的挡圈。
这种有挡圈的音圈骨架，绕上线圈后，线圈的边缘与挡圈相靠在一起，在胶水变软时，挡圈起到阻挡的作用，能有效地防止线圈从音圈骨架上脱落下来，从而提高音圈的耐温性能，延长使用寿命。
附图1是这种有挡圈的音圈骨架的结构图；
附图2是有挡圈的音圈骨架的第二种结构图；
附图3是有挡圈的音圈骨架的第三种结构图；
附图4是有挡圈的音圈骨架的第四种结构图；
附图5是有挡圈的音圈骨架的实际应用原理图。
如图1和图2所示，这种有挡圈的音圈骨架，包括一个音圈骨架1，在音圈骨架的圆柱面上绕制线圈的位置边缘有至少一条环形的挡圈2。图1和图2中都为一条挡圈。图1中的挡圈位于线圈位置的下边缘，图2中的挡圈位于线圈位置的上边缘。图中3为挡圈上穿导线线头用的缺口。
如图3所示，这种有挡圈的音圈骨架上的环形挡圈2也可以有两条，分处于线圈位置的上下两边缘处。对线圈上下两边的散圈现象都能起到有效的防止作用。
如图4所示，这种有档圈的音圈骨架也可以在线圈位置的上下两边缘和中部各有一条挡圈2。或者再多几条挡圈，更能起到对线圈的固定作用。
如图5所示，这种有挡圈的音圈骨架使用时，线圈4粘在音圈骨架的下端，线圈的边缘与挡圈2相靠，能起到很好的防止线圈散圈的作用。线圈的外表面还可以贴上一层固定膜5，也能起到加固线圈的作用。音圈骨架如果采用铝合金来制作，还能起到对线圈散热、降温的作用。

Claims (3)
