<p>Displacement of a moving diaphragm in an electroacoustic transducer is measured by modulating an electrical signal based on changes in capacitance between the voice coil assembly and the magnetic structure resulting from relative motion between the voice coil and the magnetic structure. The modulated electrical signal is demodulated to produce an output signal having a value proportional to the displacement.</p>
