A Study of Electrostatic Forces in Single-Acting Condenser Digital Transducer

Popis výsledku v původním jazyce

One of the possibilities to design a transducer with the direct digital-to-analog conversion, sometimes called a digital loudspeaker, is the miniature condenser transducer manufactured on a silicon chip. Only recently this micro technology has been madeavailable commercially, which opens further application possibilities. The proposed article is aimed at the study in which the back electrode of the electrostatic transducer is partitioned into sections having total areas proportional to powers of 2. Since the electrostatic force acting on the membrane is affected by the distribution of bit groups, which cannot be even, said electrostatic force will not be a linear function of the signal voltage. Correction coefficients for some arrangements are searched for.
