Abstract: A loudspeaker arrangement includes a loudspeaker and a trigger circuit for electrically triggering the loudspeaker. The loudspeaker has a loudspeaker diaphragm for generating an acoustic signal. A digital pulse test signal is applied to the loudspeaker via the trigger circuit during a respective test sequence, the digital pulse test signal having a duty cycle that is predetermined to change such that the duty cycle increases over a plurality of periods of the test sequence at the beginning of the test sequence, and the duty cycle decreases over a plurality of periods of the test sequence at the end of the test sequence. During the respective test sequence, a measurement variable, representative of a voltage drop on a reference circuit connected in series to the loudspeaker, is detected, and the loudspeaker arrangement is classified as functional on the basis of a comparison of the measurement variable and a predetermined reference value.
