Hearing aid with pull-out-string, pull-out string, and method of making a hearing aid |
摘要 |
A pull-out string for connection to a hearing aid which is constructed for use in an ear canal near a tympanic membrane. The pull out string has two ends and a fixing element at each end for connection to the hearing aid. The pull-out string has a plurality of beads, the distance from each bead to an end of the pull-out string being unique. In a method of manufacturing a hearing aid provided with such a pull-out string, the pull-out string is secured to the hearing aid at one end and is severed at a desired distance from the hearing aid such that the pull-out string has a bead at the resulting free end. This results in a hearing aid having a pull-out string whose length can be chosen from many possible values and whose free end can be gripped satisfactorily.
