<p>An apparatus for transducing between an acoustical signal and an electrical signal, comprises a backplate assembly comprising a charged layer and a conductive layer and a diaphragm assembly positioned at a predetermined distance from the backplate assembly. The diaphragm assembly comprising a support structure and a diaphragm, the diaphragm vibrates in response to an acoustical signal, is monolithically formed on the support structure, wherein the support structure and the diaphragm are composed of a common material having a thermomechanical property. The apparatus further comprises a spacer, a printed circuit board (PCB), and a housing. The spacer is formed between the backplate assembly and the diaphragm assembly, collectively constituting a motor portion. The motor portion and the PCB are disposed in the housing.</p> |
