Speaker(s): Roger Grinnip, Principal Acoustical Engineer at Shure Incorporated
Electrostatic transducers are mechanically simple and can provide a number of performance benefits when used in acoustic applications. However, electrostatic transducers carry a stigma, are viewed as exotic, and have not found mainstream acceptance except in condenser/electret microphones. To most, the complication seems to stem from the unique electrical requirements, but a close look at the basic operation uncovers additional complications that can impede the performance benefits. To shrink the electrostatic transducer down to an earphone driver, with optimal performance, requires recognizing these “potholes” and finding the path to compromise.
