Definitions

  • the invention relates to a hearing aid device which can be worn on the head of a user and has a device part which can be inserted at least partially into the auditory canal of the user and a connection piece connecting the device part to the earpiece, the hearing aid device having at least one input transducer for receiving it an input signal and conversion into an electrical input signal, a signal processing unit for processing and amplifying the electrical input signal and generating an electrical output signal, a receiver for converting the electrical output signal into an acoustic output signal and a voltage source for supplying power to the hearing aid, wherein the signal processing unit in the Device part and the listener are arranged in the earpiece and wherein the connector electrical conductors for electrically connecting the signal processing unit with the Includes handset.
  • From the DE 29801567 U1 is a portable behind the ear hearing aid with an insertable into the ear canal of a user earmold and the hearing aid to the earmold connecting flexible mounting bracket known in which the handset is located in the earmold and the mounting bracket electrical lines for connecting the handset with the behind the Ear-portable hearing aid includes.
  • the mounting bracket is detachably connected by jack and jack sockets with both the behind the ear portable hearing aid and with the earmold.
  • a sound tube to the sound outlet of the hearing aid.
  • the sound outlet of a hearing aid is often provided with a cerumen protection device.
  • a cerumen protection device Used as a cerumen protection device a membrane and in particular a closed, ie non-porous membrane used, so for the barometric pressure equalization venting for the trapped between the listener and the membrane volume is required. This closed-loop ventilation ensures that the static pressure on both sides of the membrane is the same and corresponds to the ambient air pressure. As a result, a distortion of the membrane is avoided with the resulting acoustic disadvantages.
  • the handset itself also requires a ventilation of the receiver diaphragm for barometric pressure equalization of the volume enclosed between the receiver diaphragm rear side and the receiver housing and not connected to the sound outlet opening of the receiver.
  • an opening usually in the form of a precision bore, is provided in the housing of the listener.
  • the hole in the receiver housing and the holes in the receiver membrane must be small in order to avoid acoustic feedback and not unnecessarily reduce the efficiency of the listener. They represent acoustically a low pass with a common cutoff frequency in the range of 1 Hz or an acoustic voltage divider with a strong attenuation.
  • Hearing aid handset and in particular the ventilation holes of such handset are very vulnerable to contamination, which is why the ventilation is usually in the device interior of the hearing aid, in which a relevant handset is used, directed.
  • the surrounding hearing aid housing protects the small one Bore from direct contact or direct connection to the ear canal in which the hearing aid in question is used.
  • the air exchange with the outside air required for barometric pressure equalization then takes place via already existing leaks in the hearing aid housing, for example in the area of the battery compartment or operating elements.
  • Object of the present invention is therefore to improve the ventilation of a listener for barometric pressure equalization in a hearing aid with a portable outside of the ear canal device part and a portable ear canal in the ear canal, in which the listener is located. This object is achieved by a hearing aid with the features of claim 1.
