Abstract

When volume-changeable elements are used in earpiece apparatus, a valve apparatus for expanding and contracting purposes is provided. A valve apparatus is provided with a discharge opening for the outlet of air from the volume-changeable element. The discharge opening can be closed directly by the volume-changeable element itself.

Description

technical field [0001] The invention relates to a valve device 4 for a variable volume element 6 on an ear piece device 2 with a valve device for supplying and / or leading out a medium to the variable volume element 6 A pressure channel 8 for the medium, wherein the pressure channel 8 has a supply portion 10 which opens into the inner region 14 of the variable volume element 6 , and wherein the pressure channel 8 leads through the outlet opening 12 to the ear piece 2 and The outer area of ​​the variable volume element 6 . [0002] Furthermore, the invention relates to a method comprising: introducing an ear piece device 2 with a variable volume element 6 into the ear canal 26 , providing pressure to the variable volume element 6 through a pressure channel 8 in the ear piece device 2 . medium. Background technique [0003] Preferably, the invention is used in a hearing aid unit. A hearing aid unit is understood here to mean any sound output device which can be worn in or on...
