Abstract
The invention specifies a sealing apparatus for a microphone opening in a front plate. It comprises a sound-permeable covering medium made of a first material and a sound-permeable membrane, with a sealant arranged on the exterior of the covering medium made of a second material being designed so as to produce a tight form fit between the covering medium and the front plate when said covering medium is inserted into the microphone opening. A front plate that is compatible with the sealing apparatus according to the invention is also specified. The advantage here is that the microphone opening can be sealed in a water-tight fashion and as a result protects a microphone positioned beneath it against external influences.
