Abstract
The pressure-difference microphone is arranged in a housing, and there is provided in one of the housing walls a single opening, directed onto the front side of the microphone, for feeding voice commands which can be produced in the acoustic near field of the housing. According to the invention, the arrangement of the microphone and/or the air volume which surrounds the microphone in this case are such that the microphone can be irradiated with sound through the opening, using the pressure-difference principle.
