Frameless audio transducer for mobile applications including optionally supported coil wire and leads

An audio transducer comprising:

• a membrane assembly, the membrane assembly comprising:
• a membrane having a top side and a bottom side and a periphery;
• and
• a ring plate assembly affixed to the periphery of the bottom side of the membrane, the ring plate assembly having two or more ring plate assembly mating elements;
• a coil assembly, the coil assembly comprising:
• a coil having a top side and a bottom side and a first lead and a second lead extending from the coil, the top side of the coil being affixed to the bottom side of the membrane;
• and
• a pair of contact pad assemblies, each contact pad assembly having:
• a body portion and a contact pad affixed to the body portion;
• wherein the body portion includes a first body mating element and a second body mating element;
• and
• a baseplate having two or more baseplate mating elements;
• wherein, when assembled, the two or more ring plate assembly mating elements interface with the first body mating elements of the pair of contact pad assemblies, and the second body mating elements of the pair of contact pad assemblies interface with the two or more baseplate mating assemblies to align the membrane assembly, coil assembly, and baseplate.
