Method for the output of acoustic signals

摘要

The invention relates to a device and a method for the output of acoustic signals. According to the invention, at least one facility part (2) of a technical facility (3) is used as a sound transducer, in that an electrical variable (= current I or voltage U) of the facility part (2) can be controlled such that the facility part (2), while using a parasitic effect, emits a sound field (SF1, SF2) in the audible frequency range from 16 Hz to 20000 Hz.
