Definitions

  • the present invention relates to a hearing aid according to the preamble of claim 1.
  • the hearing aid has a disposable in the ear plastic mold.
  • This plastic mold may be the hearing aid shell of an in-ear hearing aid or an earpiece that can be inserted into the ear, which belongs to a behind-the-ear device.
  • cerumen protection system From the speaker to the surface of the plastic mold extends a cerumen protection system.
  • a cerumen protection system protects the speaker from the ingress of cerumen. It creates a way for the sound from the speaker to the surface of the plastic mold, without cerumen can reach the speaker.
  • a hearing device in which a second acoustic sensor is provided. This is introduced together with an electroacoustic transducer (earphone) in the inner ear of the hearing aid wearer.
  • earphone electroacoustic transducer
  • This invention is achieved by placing a microphone in the cerumen protection system.
  • the invention makes use of the fact that especially in in-ear hearing aids at the tip of the hearing aid shell in height of the exit of the loudspeaker signal with a cerumen protection system can be ensured that sufficient space for a microphone is available in the cerumen protection system.
  • the cerumen protection system can be adapted to the presence of a microphone and, if necessary, be made larger accordingly.
  • the cerumen protection system may in particular be funnel-shaped.
  • the funnel shape is particularly suitable for the sound path from the speaker to the surface of the plastic mold, but ensures an expansion of the cerumen protection system in the vicinity of the surface of the plastic mold in which the microphone can be attached.
  • the funnel shape has a conical section that merges into a tubular section that extends to the surface of the plastic mold.
  • the microphone can either be arranged so that it is arranged with its diaphragm parallel to the sound outlet opening.
  • the microphone can record the sound in the ear canal particularly well.
  • the microphone can be arranged with its microphone diaphragm perpendicular to the sound outlet opening. In this embodiment, a particularly space-saving arrangement is ensured in particular with the funnel shape of the cerumen protection system.
  • the tubular portion may be of elliptical cross section, ie the cerumen protection system may have an elliptical cross section when hitting the surface of the plastic mold.
  • a microphone with a circular cross-section can then be fitted particularly well into the elliptical shape.
  • the hearing aid is housed in a plastic mold, in a so-called hearing aid shell.
  • the plastic mold has a tip which is inserted into the ear canal.
  • a tip 10 of an in-ear hearing aid according to the invention is shown in FIG 1 in the lateral section.
  • a speaker 12 is provided at the top 10.
  • the opening of the speaker 12 is not located directly on the surface of the plastic mold.
  • a cerumen protection system 14 is provided, which is shown funnel-shaped here.
  • the funnel shape has a small plug-like tubular portion at the bottom, then a widening portion, which in particular can also be conical, and then again a tubular portion which extends to the surface of the plastic mold 10.
  • a protective membrane 16 is provided above the sound outlet or the cerumen protection system, which is here shown open-pore, but may also be a closed protective membrane.
  • the space for receiving a microphone 18 is created.
  • the microphone 18 is arranged here so that it extends parallel to the surface of the plastic mold and thus parallel to the protective membrane, the microphone 18 being defined primarily by its microphone sound recording surface (eg the membrane, which is not specifically shown) is arranged parallel to the protective membrane.
  • FIG. 2 shows a top view of the tip 10 of the plastic mold of the in-the-ear hearing device according to the invention.
  • the tubular portion of the funnel shape 14 emerges here in a particularly elliptical cross section on the surface of the tip 10 in the plastic mold.
  • the elliptical shape is marked 20.
  • the microphone 18 fits into the elliptical shape 20 with a circular contour 22.
  • FIG. 3 shows an alternative embodiment of the in-the-ear hearing device according to the invention. Equal parts of the tip 10 of the in-ear hearing aid according to the invention are provided with the same reference numerals.
  • the embodiment according to FIG. 3 differs from that of FIG. 1 in the orientation of the microphone, which is designated here by 18 '.
  • the microphone can be designed as a particularly small sound pickup, which does not reach the level of conventional ear canal microphones qualitatively.
  • the invention makes use of the fact that in the cerumen protection system a suitable space is available to accommodate the microphone.
  • the cerumen protection system is adapted to the specific needs of accommodating the microphone.
  • the shown funnel shape with flared portion and subsequent tubular portion is particularly suitable for receiving a microphone.
