具备安装有音圈的振动板的扬声器单元制造技术

本发明专利技术提供一种能够抑制引线的断线不良的扬声器单元。扬声器单元具备振动板、固定在振动板上的音圈、与音圈连接且向音圈通电的引线。振动板包括固定音圈的环状的固定部、相对于固定部向固定有音圈的面侧突起且沿着固定部延伸的外侧凸部。外侧凸部具有顶部。在外侧凸部形成有顶部的一部分凹陷的凹陷部。引线在凹陷部的内部配置成横穿外侧凸部。

Speaker unit having a vibrating plate mounted with a voice coil

The present invention provides a speaker unit capable of suppressing undesirable disconnection of lead wires. The speaker unit is provided with a vibrating plate, a sound coil fixed on the vibration plate, a lead connected with the voice coil and energized to the voice coil. The vibrating plate comprises an annular fixing part of a fixed sound ring and a lateral projection projecting along the surface of the sound ring relative to the fixing part and extending along the fixed part. The outer convex portion has a top. A concave portion with a depression at the top is formed at the outer convex portion. The leads are arranged inside the recessed portion to cross the outer projection.
