摘要

基于铜镍纳米复合材料电阻率和磁导率的权衡，提出了一种用于低功率电磁微扬声器制造的优化铜镍纳米复合材料线圈。在碱性非氰化铜基镀液中镀上200 μ m宽的复合线圈，并添加2g/L的Ni纳米粉末，在1至6kHz的频率范围内，与纯Cu线圈相比，扬声器的功耗可以节省40%。

An optimized Cu-Ni nanocomposite coil for low-power electromagnetic microspeaker fabrication

This paper presents an optimized Cu-Ni nanocomposite coil synthesized based on the trade-off of resistivity and permeability of the nanocomposite for low-power electromagnetic microspeaker fabrication. A 200µm wide composite coil plated in an alkaline noncyanide copper based bath that is added with 2g/L of Ni nanopowders can realize ∼40% power saving of the speaker performed in a frequency range of 1 to 6kHz as compared with the coil made of pure Cu for the same speaker design.
