Embodiment Construction

[0028] FIG. 1 shows an example of a hearing aid according to the prior art, in particular a hearing aid worn behind the ear, in a greatly simplified block diagram. A hearing aid basically comprises an input converter, an amplifier and an output converter as main components. The input converter is typically an acoustic receiver, such as a microphone, and / or an electromagnetic receiver, such as an induction coil. Output transducers are mostly implemented as electroacoustic transducers, such as small speakers or headphones, or electromechanical transducers, such as bone conduction headphones. Amplifiers are usually integrated in signal processing units. In the exemplary embodiment according to FIG. 1, one or more microphones 2 for receiving sound from the surrounding environment are incorporated in a hearing aid housing 1 designed to be worn behind the ear. A signal processing unit 3 , which is likewise located in the hearing aid housing, processes and amplifies the microphone ...

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.

Description

technical field [0001] The invention relates to a microphone protection device for preventing dust and / or moisture from entering the sound inlet of the microphone, comprising a dust-tight and / or hydrophobic and / or dust- and / or moisture-impermeable membrane. [0002] Furthermore, the invention relates to a hearing aid with a corresponding microphone protector and a microphone unit with a microphone and a microphone protector. Background technique [0003] Microphone protection should prevent dust and moisture from entering the microphone as completely as possible. Furthermore, the microphone protector should attenuate the sound input signal into the microphone as little as possible. Furthermore, the microphone protector should function for as long as possible, especially without clogging. These requirements can only be met by providing a larger surface for the membrane of the microphone protector. But this runs counter to the miniaturization being pursued in hearing aids. ...
