The speakers use a thin flat diaphragm usually consisting of a plastic sheet coated with a conductive material such as graphite sandwiched between two electrically conductive grids with a small air gap between the diaphragm and grids.
Electrostatic plastic sheet.
Calsak plastics carries static dissipative pvc acrylic and polycarbonate for use in cleanroom glazing and structural applications as well as for use in dessicator cabinets and other cleanroom product applications.
It is defined as the electrostatic force in newtons on a hypothetical small test charge at the point due to coulomb s law divided by the magnitude of the charge in coulombs.
The electric field in units of newtons per coulomb or volts per meter is a vector field that can be defined everywhere except at the location of point charges where it diverges to infinity.
It s an old account of a weird phenomena created by giant plastic sheets at 3m corporation in short.
