Definitions

  • the present invention relates to a sound tube for transmitting sound from a hearing device worn on the ear to the auditory canal of the user with a piece of tubing at one end of which an adapter is attached for connection to the hearing device.
  • hearing device is understood here in particular a hearing aid, but also any other ear-portable sound-emitting device, such as headphones, headset and the like.
  • the present invention is therefore specifically directed to a hearing aid with a sound tube mentioned above.
  • Hearing aids are portable hearing aids that are used to care for the hearing impaired.
  • different types of hearing aids such as behind-the-ear hearing aids (BTE), hearing aid with external receiver (RIC: receiver in the canal) and in-the-ear hearing aids (IDO), e.g. Concha hearing aids or canal hearing aids (ITE, CIC).
  • BTE behind-the-ear hearing aids
  • RIC hearing aid with external receiver
  • IDO in-the-ear hearing aids
  • ITE canal hearing aids
  • the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
  • Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
  • the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
  • the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
  • the amplifier is usually in one Signal processing unit integrated. This basic structure is in FIG. 1 shown using the example of a behind-the-ear hearing aid. In a hearing aid housing 1 for carrying behind the ear, one or more microphones 2 for receiving the sound from the environment are installed.
  • a signal processing unit 3 which is also integrated in the hearing aid housing 1, processes the microphone signals and amplifies them.
  • the output signal of the signal processing unit 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal.
  • the sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier.
  • the power supply of the hearing device and in particular of the signal processing unit 3 is carried out by a likewise integrated into the hearing aid housing 1 battery. 5
  • z. B. BTE hearing aid For behind or on the ear worn hearing aids, z. B. BTE hearing aid, the sound is guided by means of a sound tube to the ear. It is desirable that the sound tube is visually designed as little as possible conspicuous. Therefore, try to keep this tube as short as possible and also to the ear as far as possible to cling. For this purpose, custom sound tube formations are performed on high-priced hearing aids. Low-price devices try to cover the individual needs as far as possible with as few standard forms as possible. For example, for low-cost devices at least three different lengths of flexible sound tubes are currently provided, which also serve as a support hook for the hearing aid.
  • these sonic tubes are preformed, they are each to be provided as a left and right variant for a hearing aid to be worn on the left and a hearing aid to be worn on the right. This means that at least six sound tube variants are to be provided. This in turn requires six different manufacturing forms and six different part numbers. Overall, so arise increased storage and manufacturing costs for low-price hearing aids.
  • Such a hearing aid is for example from the patent US Pat. No. 6,681,022 B1 known.
  • a universal ear piece eartip
  • the sound tube also serves as a carrying hook and has several curvatures. Depending on the type of wear on the left or right ear, therefore, a suitable sound tube is to be selected.
  • a similar sound tube is also from the patent US 6 009 183 A known. There, too, the sound tube for wearing the hearing device on the left ear or on the right ear is interchangeable.
  • a hearing aid system with a hearing aid and a portable ear earmold known.
  • a sound tube with a quick coupling is used for detachable connection of the hearing aid with the earmold.
  • the sound tube may be directly connected to the earmold and the quick coupling may be between the free end of the sound tube and the top of the hearing aid.
  • the sound tube can also be divided into two tube sections, which can be connected and disconnected by means of the quick coupling.
  • EP 1 853 088 A2 an earmold to which a piece of tubing is mounted. This piece of tubing is plugged into another tube which connects to a hearing aid.
  • EP 0 997 057 B1 a behind-the-ear hearing aid system in which a tube of a hearing aid can be inserted into an ear piece.
  • a tube of a hearing aid can be inserted into an ear piece.
  • the Sound tube is stiffer than conventional hearing aids and may be provided at its end with annular barbs so that it can be firmly inserted into the earpiece.
  • the object of the present invention is to provide a sound tube for a hearing device which on the one hand conforms well to the respective ear and on the other hand brings low storage and manufacturing costs.
  • this object is achieved by a sound tube for transmitting sound from a hearing device worn on the ear to the auditory canal of the user, with a first piece of tubing, at the first end of which an adapter is attached for connection to the hearing device, further comprising a two-piece with the first piece of tubing formed second tube piece and a connecting piece, on the one hand, the second end of the first piece of hose and on the other hand, an end of the second piece of hose are fixed, wherein the connecting piece ensures that the first piece of hose relative to the second piece of hose is rotatable or pivotable.
  • the sound tube both for a hearing device that can be worn on the left ear and on the right ear.
  • the variety of variants of the acoustic tubes to be provided can be reduced, which ultimately reduces the storage costs and production costs for the hearing devices.
  • an adapter for an ear piece is attached to the free end of the second tube piece.
  • This ear piece may be, for example, an ear tip or a universal ear piece, which fixes the sound tube in the ear canal.
  • the second piece of tubing may have a prefabricated curvature in one spatial direction.
  • the connecting piece may be tubular and the two pieces of hose are rotatable relative to each other with respect to the longitudinal axis of the connecting piece.
  • one hose piece can be inserted into the first side of the connecting piece and the other hose piece into or onto the second side of the connecting piece. Due to the rotational symmetry of the connector, the pivot bearing can be easily realized here.
  • one of the two pieces of hose can be put on the connecting piece.
  • the insertion depth is variable.
  • the sound tube is variable in another dimension.
  • the connector in the axial direction one behind the other can have a plurality of circumferentially extending barbs on / to which one of the two pieces of tubing is rotatably inserted.
  • the barbs By the barbs, the friction is increased in the axial direction, but allowed due to their course in the circumferential direction of rotation.
  • first and / or second piece of hose is flexible.
  • a deformability is achieved, which is necessary to better adapt the sound tube individually.
