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 200 mum wide composite coil plated in an alkaline noncyanide copper based bath that is added with 2 g/L of Ni nanopowders can realize ~40% power saving of the speaker performed in a frequency range of 1 to 6 kHz as compared with the coil made of pure Cu for the same speaker design.
