2. Thermal Modelling of Voicecoils in Microspeakers
University essay from Linköpings universitet/ReglerteknikAbstract : Microspeakers can overheat and break if not monitored and regulated. This monitoringis usually done by adding a pilot tone that introduces energy to the signal.A problem with this approach is the slow update rate of the temperature estimate.This in combination with a fast temperature rise could result in an audible regulationof the input.
