Abstract (en)
[origin: WO2012022382A1] In order to protect a microphone from moisture and/or dirt, the invention aims to produce a microphone protective device (22, 32) that needs only relatively little space for installation into an electroacoustic device for a relatively large effective surface area. For this purpose, the invention relates to a microphone protective device (22, 32) having an at least partially cylindrical-shell-shaped membrane (24, 34), for preventing dirt and/or moisture from entering a sound inlet opening (26, 37) of a microphone (21, 31).
