Abstract
In order to protect a microphone from moisture and/or dirt, there is provided a microphone protective device that needs only relatively little space for installation into an electroacoustic device for a relatively large effective surface area. For this purpose, the novel microphone protective device has an at least partially cylindrical-shell-shaped membrane, for preventing dirt and/or moisture from entering a sound inlet opening of the microphone.
