Abstract
A frameless audio transducer for mobile applications is provided. The invention relates to an audio transducer realized as speaker to transduce an electrical audio signal into acoustic sound or realized as receiver to transduce an acoustic sound into an electrical audio signal, which audio transducer is realized without a frame to align and fix the other parts of the audio transducer. The frameless audio transducer further includes coil lead support structures to reduce stress on the coil leads during operation.
