摘要:
The present invention relates to a miniature electro-acoustic transducer comprising a voice coil comprising an air gap voice coil portion at least partly positioned in an air gap of a magnet assembly, and a second voice coil portion attached to a diaphragm of the miniature transducer. The thickness of the second voice coil portion is 2-5 times larger than the thickness of the first voice coil portion. Moreover, the present invention relates to a voice coil for use in a miniature electro-acoustic transducer.
