Abstract
A membrane (112) for an acoustic device including an electrical conductor (120) integrally formed within the membrane (112). The integrally formed electrical conductor (120) may be net-shaped and may be formed between two or more layers of membrane material. The integrally formed electrical conductor (120) may be electrically connected to the voice coil in an acoustic device, wherein the integrally formed electrical conductor (120) is adapted to provide an electrical signal to the voice coil during operation of the acoustic device. Additionally or alternatively, the integrally formed electrical conductor (120) may be electrically connected to one or more electrical and/or electronic components (240) affixed to the membrane (112).
