摘要： The invention regards an audio device and comprises a microphone and a sound canal allowing sound to pass from the surroundings to the microphone. Further a signal path from the microphone to a receiver is provided and powered by a current source, such that sounds received at the microphone may be enhanced and presented at the ear level of the user. According to the invention a protection screen is provided at the sound canal, whereby the screen comprises a first surface which faces the surroundings and a second surface which faces the sound canal whereby the screen has a slit formed opening between the first surface and the second surface whereby the transition between the first surface and the slit formed opening is smooth and gradual, and whereby a sharp edge forms the transition between the second surface and the slit formed opening.
