摘要

The membrane (10) has a membrane main structure comprising a non-woven structure that is formed by electro-spinning of fibers in the form of nanofibers with diameter of 200nm and 500nm or in the form of microfibers with a diameter of 1mu m-3mu m. The membrane main structure is made of polylactic acid or flupropolymer. The membrane main structure is held by plastic made holding frame (11). The holding frame is fixed in front of opening in hearing aid by a fastening unit (12). Independent claims are included for the following: (1) cover; (2) hearing aid; and (3) method for manufacturing hearing aid.
