Description

一种导电件及发声装置 技术领域
本发明涉及电声技术领域，更具体地，本发明涉及一种导电件及发声装置。
背景技术
现有发声装置等电子产品一般包括注塑于其壳体中的导电件，电子产品内的电子元件通过导电件与外部电路电连接在一起。
尤其是，在发声装置中，其振动组件一般包括音圈。注塑于其外壳中的导电件将音圈与外部电路电连接在一起，以输入声音电信号。
在导电件上设有用于与音圈引线焊接在一起的焊盘，以及用于与外部触盘上的触点弹性接触的弯折部分。因而，现有导电件一般由不锈钢材质制成，以保证导电件的硬度以及弯折的可靠性。
但是，导电件完全由不锈钢材质制成，会导致导电件的整体阻抗值大，导致信号传递的不通畅。实践中，完全由不锈钢材质制成的导电件的阻抗值一般大于0.08Ω。
尤其是，发声装置的振动组件一般通过导电件与外部电路电连接在一起。导电件阻抗值大会影响信号的传递，导致灵敏度低，进而影响声学性能。
此外，不锈钢导磁率高，会影响发声装置等电子产品的整体天线性能。
因此，有必要对现有导电件进行改进。

该实施例中，所述第二电连接部102穿出所述壳体14的方式可以有多种。可选地，参考图2，在所述壳体14上设有避让槽。所述第二电连接部102的部分穿出所述避让槽。例如，所述触点1022的位置可高出于所述避让槽周侧的壳体14外表面。
该实施例中，所述第二电连接部102上的触点1022需与外部电连接件电连接在一起。可选地，参考图1至图3，所述第二电连接部102还可以包括第三弯折位置1023。所述第三弯折位置1023位于所述中间部101 与所述第一弯折位置1020之间。在所述第三弯折位置1023，沿所述中间部101的宽度方向弯折。这样，能使所述触点1022与外部电连接件之间的位置相对应。
此外，参考图1至图3，由于所述壳体14结构、外部电连接件位置的限制，所述中间部101可弯折设置。
所述中间部101的弯折位置材质可与其他位置材质保持一致。例如，所述中间部101可全部由铜材质制成。
所述中间部101的弯折位置材质也可与其他位置材质不同。例如，所述中间部101的弯折位置材质可由不锈钢等高机械强度材质制成。
这样，通过所述中间部101的弯折设计，能使得所述第一电连接部100对应于所述发声装置组件的位置，所述第二电连接部102对应于外部电连接件的位置。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
