  • the invention relates to an in-the-ear hearing aid (ITE hearing aid) for insertion into an auditory canal with the features of the preamble of claim 1.
  • ITE hearing aid in-the-ear hearing aid
  • Such a hearing aid is for example from the DE 39 08 673 A1 refer to.
  • Hearing aids are portable hearing devices which are generally designed to emit sound. Sound is generally understood to mean an acoustic signal, for example music and / or speech.
  • a hearing device is generally understood to mean any device which can be worn in or on the ear and produces a sound stimulus, for example a headset, headphones and the like. Hearing aids are also specially designed as hearing aids.
  • a hearing aid device is understood to mean a device for the care of a hearing-impaired or hearing-impaired person, which in particular wears the hearing aid device continuously or most of the time in order to compensate for a hearing deficit. According to general usage, hearing aids are also referred to as hearing aids.
  • hearing aids such as behind-the-ear hearing aids (BTE), hearing aids with external earphones (RIC: receiver in the canal) and in-the-ear hearing aids (ITE),
  • BTE behind-the-ear hearing aids
  • RIC hearing aids with external earphones
  • ITE in-the-ear hearing aids
  • concha hearing aids or channel hearing aids ITE, CIC
  • the hearing aids listed by way of example are worn on the outer ear or in the auditory canal.
  • implantable or vibrotactile hearing aids are available. The damaged hearing is stimulated either mechanically or electrically.
  • An ITE hearing aid and a method for producing such an ITE hearing aid are known from US Pat US 6 473 512 B1 refer to.
  • the described ITE hearing aid has a particularly elastic housing in order to improve wearing comfort.
  • the ITE hearing aid has a ventilation channel and a microphone arranged on an end wall (also called a faceplate).
  • ITE hearing aids are from the DE 39 08 673 A1 , the EP 2 986 032 A1 as well as the DE 202 08 601 U1 refer to.
  • a ventilation channel is formed between an outer wall and an inner wall.
  • the ventilation duct is also used as a sound duct.
  • a breakthrough to a microphone is formed in the inner wall.
  • a housing of a hearing aid in particular an ITE hearing aid, is adapted to an auditory canal of a user.
  • the object of the invention is to provide an ITE hearing aid with a large recording space.
  • the ITE hearing aid hereinafter referred to briefly as a hearing aid, is designed to be inserted into an auditory canal of a user.
  • the hearing aid has a housing which has an end wall and a side wall.
  • the inserted side wall is oriented towards an inner wall of the auditory canal of the user.

  • the housing of the hearing aid is preferably adapted in a user-specific manner.
  • the front wall When inserted, the front wall is oriented towards the front, ie it runs across the ear canal. The end wall completely or at least largely covers the opening to the auditory canal.
  • the hearing aid has at least one microphone for recording sound, for example speech and / or music.
  • the microphone is designed, for example, in the known manner of a sound transducer.
  • the hearing aid also has a sound opening arranged on an end wall of the housing for transmitting sound to the at least one microphone.
  • the sound opening is connected to the microphone via a sound channel, the sound channel being at least partially formed by a lateral recess in the side wall of the housing.
  • a wall thickness of the side wall at the location of the sound channel is at least reduced, so that the sound channel is integrated into the side wall.
  • the sound channel therefore runs at least partially within the side wall adapted to the auditory canal of the user.
  • the recess generally reduces the wall thickness of the side wall in the region of the sound channel from the inside of the side wall. The sound channel therefore runs along the side wall.
  • an interior is enlarged to accommodate the individual hearing aid components.
  • the microphone preferably has a sound inlet which is oriented in the direction of the recess.
  • sound entry is understood to mean a part of the at least one microphone which, for example, has a membrane for receiving the sound.
  • the microphone is generally positioned on the side next to the sound channel and delimits the recess on the side. Ie the microphone forms a boundary of the sound channel.
  • the microphone here is general understood a component which has a microphone housing with the sound inlet opening and a sound transducer lying inside the microphone housing. The sound channel therefore extends from the front wall within the side wall (in the direction of the side wall and thus in the direction of the ear canal).

  • a holder which is connected to the side wall and on which the at least one microphone is arranged.
  • the microphone is thus arranged laterally in the housing, so that a sufficient pick-up of the incoming sound is ensured.
  • the recess is open towards the end wall, i.e. the recess has no frontal boundary in the area of the side wall. This allows the recess to be produced easily.
  • the wall thickness of the side wall is reduced to form the recess, in particular only at the location of the recess.
  • the side wall has a larger wall thickness.
  • the sound channel thus runs, in particular, on the inside of the housing.

  • the advantage is that the sound channel can be easily integrated laterally into the side wall of the housing.
  • the recess is preferably designed as a wall opening.
  • a wall opening is understood to mean that the side wall is completely removed at the point of the cutout, so that the sound channel is open laterally towards the auditory canal.
  • the lateral recess of the sound canal is therefore only made in the inserted state through an inner wall of the auditory canal of the user.
  • the wall opening is at least and preferably only limited on three sides by a material of the side wall.
  • the three sides are preferably understood to mean all sides of the, in particular, rectangular recess, with the exception of the side which faces the end wall of the housing.
  • the sound channel is therefore formed by a slot-like opening in the side wall, which is open towards the front wall.
  • the at least three sides of the recess therefore only form an approximately U-shaped boundary. At least one, preferably both, of the intermediate surfaces spanned by this U-shaped boundary is / are open.
  • the recess is bounded on the outside by a material film.
  • “outward” is understood in the direction of the inner wall of the auditory canal of the user.
  • material film is specifically understood to cover the recess, for example in the manner of a film, in particular a water-repellent film.

  • the battery flap For this purpose, the battery flap For example, a material projection that has a bore as a sound opening, for example. The material projection covers an entrance to the sound channel. This in particular prevents, for example, dirt and / or cerumen from penetrating into the sound channel. At the same time, a "penetration" of the sound through the bore is ensured.
  • the battery flap has a protective element extending into the recess.
  • the protective element is preferably angled on the battery flap in the direction of the sound channel. It is used in particular to remove dirt, for example cerumen, that has penetrated into the recess.
  • the protective element is arranged on the battery flap in such a way that when the battery flap is opened, the protective element is pulled out of the recess and thus carries the dirt out of the recess.
  • the protective element is at least partially in contact with wall areas that delimit the recess.
  • the protective element bears in a form-fitting manner on the wall areas in the recess.
  • the protective element is expediently designed as a frame, which in particular lies positively in the recess.
  • this embodiment has the further advantage that the protective element does not cover the sound entry of the microphone and thus an undisturbed and undamped pickup of the sound from the microphone is ensured.
  • the ITE hearing aid described is designed as a channel hearing aid, preferably as a completely-in-the-canal hearing aid (CIC hearing aid).
  • CIC hearing aids of this type the end wall of the housing is arranged, for example, inclined in the direction of the auditory canal, as a result of which CIC hearing aids are optically inconspicuous.
