An electrostatic transducer, a diaphragm (2) therefor, and corresponding methods of manufacture are disclosed. The electrostatic transducer is preferably for use in a motor vehicle. A composite laminated diaphragm (2) is manufactured by providing a first insulating layer (4), providing a conductive layer (6) on a surface of the first insulating layer (4), and bonding a second insulating layer (10) to the conductive layer (6) such that the second insulating layer (10) extends over the conductive layer (6). The first and second insulating layers (4, 10) each comprise a sheet of uncharged insulating material. The thickness of the composite laminated diaphragm (2) is less than 20 μm. Manufacturing the electrostatic transducer comprises securing a first conductive stator, a first insulating spacer and the diaphragm (2) in a stack with the first insulating spacer between the first conductive stator and the diaphragm (2) to provide a spacing of less than 1 mm between the first conductive stator and the diaphragm (2).
A method of manufacturing an electrostatic transducer suitable for use in a motor vehicle, the method comprising manufacturing a composite laminated diaphragm and assembling the electrostatic transducer;
An electrostatic transducer suitable for use in a motor vehicle comprising:
