Abstract
A new audio transducer for mobile devices, in particular for a micro speaker, having a coil assembly having a coil, a pair of leads extending from the coil, and a flexible printed circuit having a pair of contact pads to which the leads are directly electrically connected. An advantage of this new speaker is the reduced number of electrical connections between the leads of the coil and the driver of the coil. This helps to reduce the number and size of the parts of the micro speaker and aids in increasing sound quality and durability of the speaker.
