Patent number: 10277970Abstract: There is provided a microphone unit (1) for an action camera, comprising a microphone capsule (10) having at least one speaking hole (11), and a water-tight enclosure (20) which water-tightly encloses the microphone capsule (10). The water-tight enclosure (20) has a water-impermeable passive diaphragm (25) which can oscillate freely and which allows incoming sound to pass substantially undisturbed. The microphone unit has a head (30) having a plurality of holes (31), the head (30) being provided outside the enclosure (20) in front of the passive diaphragm (25). The microphone unit further has a foam portion (40) which is provided in front of the head (30) and has an open-pore foam. The foam portion (40) is in contact with the head (30). The passive diaphragm (25) has an oscillatable minimum area of 20 mm2; wherein the foam portion (40) has pores which are sufficiently small so that the foam portion (40) can suck water residues away from the holes (31) in the head (30) like a sponge.Type: GrantFiled: September 1, 2017Date of Patent: April 30, 2019Assignee: Sennheiser electronic GmbH & Co.
