Abstract
The invention relates to a method for protecting a component () within an audio device () from the exceedance of a maximum internal temperature (TI), wherein a power loss (V) of the component () is determined, a measurement temperature (TM) is measured on the component (), a temperature difference (DT) for the component () between the measurement temperature (TM) on the component and the internal temperature (TI) is determined from the power loss (V) by means of a thermal model () of the component (), the internal temperature (TI) is determined as the sum of the measurement temperature (TM) and the temperature difference (DT), a permissible maximum value (VM) for the power loss (V) is determined on the basis of the internal temperature (TM) and known component data () of the component (), and the component () is operated in a normal operating mode (N) if the power loss (V) does not exceed the maximum value (VM) or the component () is otherwise operated in reduced-power economy operating mode (S) such that the power loss (V) is limited to the maximum value (VM). An audio apparatus (), having an audio device () that internally contains a component () that should be protected from the exceedance of a maximum internal temperature (TI), contains a protection module () for carrying out the method according to the invention.
