Abstract (en)
[origin: EP1841288A2] The sounding unit is composed of the sound outlet opening and ring-shaped cerumen protection unit. The ring-shaped cerumen protection unit has an open-porous material that protects the sound outlet opening (3) against a cerumen of the user. The cerumen protection unit is attached to the sound outlet opening so that the sound penetrates through the ring opening of the protection unit. The open-porous material is made from sponge (1) and absorbs the cerumen. An independent claim is also included for a protection method of sounding unit of hearing apparatus.
