Definitions

  • the invention relates to a deep-ear canal hearing instrument, in particular a hearing aid, for carrying deep in the ear canal of a user.
  • Hearing instruments can be designed as hearing aids.
  • a hearing aid is used to supply a hearing-impaired person with acoustic ambient signals that are processed and amplified for compensation or therapy of the respective hearing impairment. It consists in principle of one or more input transducers, of a signal processing device, of an amplification device, and of an output transducer.
  • the input transducer is typically a sound receiver, e.g. a microphone, and / or an electromagnetic receiver, e.g. an induction coil.
  • the output signal generator is usually as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z.
  • the output signal generator generates output signals that are routed to the patient's ear and are intended to produce a hearing perception in the patient.
  • the amplifier is usually integrated in the signal processing device.
  • the hearing aid is powered by a battery integrated into the hearing aid housing.
  • the essential components of a hearing aid are usually arranged on a printed circuit board as a circuit carrier or connected thereto.
  • Hearing instruments can be designed as a hearing aid, which is the compensation of a weakened or impaired hearing, commonly referred to as deafness, may also be designed as a so-called tinnitus masker.
  • Tinnitus maskers are used to treat tinnitus patients. They produce from the respective hearing impairment and depending on the principle of action also dependent on ambient noise acoustic Output signals that may contribute to reducing the perception of annoying tinnitus or other ear noises.
  • the term hearing instrument should also be understood tinnitus masker and other such devices.
  • Hearing aids are known in various basic housing configurations.
  • ITE hearing aids in-the-ear, in-ear
  • a housing containing all the functional components, including the microphone and receiver is mostly worn in the ear canal.
  • Completely-in-Canal (CiC) hearing aids are similar to the IdO hearing aids, but are fully worn in the ear canal.
  • BTE hearing aids behind-the-ear, behind-the-ear
  • a housing with components such as battery and signal processing device behind the ear is worn and a flexible sound tube, also referred to as tube, directs the acoustic output signals of a receiver from the housing to the ear canal.
  • RiC-BtE hearing aids (Receiver-Canal behind-the-ear) are similar to BTE hearing aids, but the receiver is worn in the ear canal and instead of a sound tube, a flexible earpiece tube conducts electrical signals instead of acoustic signals to the receiver, which is attached to the front of the tube , All housing configurations have in common is that as small a housing as possible be sought in order to increase the comfort and to reduce the visibility of the hearing aid for cosmetic reasons.
  • Deep-ear canal hearing aids are similar to the CiC hearing aids. However, while CiC hearing aids are typically worn in the outer portion of the external ear canal, deep ear canal hearing aids are advanced further toward the eardrum and at least partially supported in the inward portion of the external ear canal.
  • the outer ear canal is a skin-lined canal connecting the pinna to the eardrum.
  • this channel is formed of elastic cartilage.
  • proximal part of the channel is formed by the temporal bone and thus consists of bone.
  • the cartilaginous and bony parts of the ear canal are slightly bent towards each other so that they enclose a different angle from person to person.
  • the bony part of the ear canal is relatively sensitive to pressure and contact.
  • Deep-ear canal hearing aids are at least partially worn in the delicate bony part of the ear canal. When advancing into the bony part of the ear canal, they must also pass the mentioned kink, which can be difficult depending on the angle of the kink. In addition, small diameter and tortuous shapes of the ear canal can further complicate advancement. Deep-ear canal hearing aids must therefore be very small.
  • an ear canal hearing aid which is flexibly flexible designed to be able to adapt to the ear canal.
  • the electronic components of the hearing aid are arranged in different and mutually flexibly bendable housing parts.
  • the flexible bending connection is subject to elastic restoring forces which, depending on the seat in the auditory canal, cause the hearing device to feel uncomfortable pressure on the auditory canal wall.
  • CiC hearing aid known to wear in the bony part of the ear canal.
  • the housing of the hearing aid also has a flexibly bendable section.
  • the object of the invention is to provide a deep-ear canal hearing instrument that is inexpensive to manufacture and use, which has a small size, and comfortable deep in the ear canal, especially in the bony part of the ear canal is to be worn.
  • the invention solves this problem by a hearing instrument having the features of the independent claim.
  • a basic idea of the invention consists in a hearing instrument for carrying its ear canal with a housing, a signal processing device, and a receiver.
  • the signal processing device is arranged in the housing.
  • the receiver is partially disposed in the housing and partially outside the housing.
  • the housing can be made smaller overall.
  • the double wall in the form of the receiver wall on the one hand and the housing wall on the other hand which also helps to reduce the size.
  • any reduction in size is helpful to facilitate the insertion of the hearing instrument and irritation in this sensitive part of the ear canal by the permanent wear of the hearing Hearing instrument in it to avoid.
  • the only partially provided inside the housing arrangement of the receiver depending on the design allow a less expensive production, since the receiver is not mounted in a completely enclosed by the housing assembly and thus, depending on the design and subsequently, for example. for servicing purposes, accessible from outside the enclosure or can be replaced.
  • the receiver is arranged in an opening of the housing.
  • the opening of the receiver is thus not only accessible in the outside of the housing arranged part accessible from the outside, but can also be mounted or removed from the outside and replaced without having to open the housing.
  • the receiver has on its outer circumference a projection, for example a circumferential sleeve.
  • the projection stands with an undercut in the opening in mutual engagement, eg a circumferential groove.
  • the undercut is formed such that the receiver is fixed by the mutual engagement against slipping out of the opening.
  • FIG. 1 a hearing instrument of the prior art is schematically shown, which is designed as ear canal hearing aid. 1 It comprises a housing 7 which has a housing shape suitable for insertion and carrying in the ear canal. Depending on the size, shape and diameter of the housing 7, the hearing aid 1 can be further or less widely inserted into the ear canal of a hearing aid wearer. If the dimensions are sufficiently small, the hearing device 1 can be inserted as far as or into the bony part of the auditory canal, so that then a deep-ear canal hearing device is present.
  • the housing 7 is usually made of plastic and can be adapted individually to the contours of an ear canal of a hearing aid wearer. For this purpose, it may be produced, for example, after acquisition of 3D data of the auditory canal in accordance with this data by injection molding or in a rapid prototyping technology by means of the RSM process (Rapid Shell Manufacturing).
  • the outer circumference of the housing 7 can be made flexible be or have a flexible coating or sheath.
  • suitable soft and flexible material for example, silicone gels are considered.
  • a microphone 4 is arranged for recording ambient sound and convert it into electrical signals.
  • the microphone 4 is the output side connected to a signal input of a likewise arranged in the housing 7 signal processing device 5.
  • the signal processing device 5 processes and amplifies signals received by the microphone 4 in accordance with a signal processing algorithm, which is also referred to as a hearing program.
  • the signal processing device 5 is connected to a receiver 2, which converts the electrical signals received by the signal processing device 5 into acoustic output signals.
  • the electronic components in the housing 7 of the hearing aid 1 are supplied by a battery 3 with the required operating energy.
  • the battery 3 may be a disposable battery or a rechargeable battery.
  • the electronic components including battery 3 are electrically connected together in a manner not shown, e.g. via wiring or via a common rigid or flexible circuit carrier.
  • the Reveiver 2 outputs the acoustic output signals through a receiver opening 6 in the housing 7 to the outside.
  • the receiver opening 6 is arranged in the proximal side of the housing 7 to be supported in the auditory canal, so that the output signals are emitted in the direction of the eardrum of the hearing aid wearer.
  • the receiver 2 itself is arranged completely inside the housing 7. With the outside it is connected only via the receiver opening 6.
  • FIG. 2 a hearing instrument designed as a deep-ear canal hearing device 11 is shown schematically with a receiver 12 held by a cuff 20.
  • the receiver 12 is only partially within the housing 17 of the hearing device 11 arranged, but sometimes outside. He sticks out of the housing 17.
  • the housing 17 surrounds the receiver 12 only partially, which is why the housing 17 has a correspondingly smaller size.
  • the receiver 12 projects out of the proximal side of the housing 11 to be supported in the auditory canal, so that the diameter of the hearing device 11 in the proximal region is reduced to the diameter of the protruding part of the receiver 12.
  • the receiver 12 is arranged in an opening 18 of the housing 11.
  • a circumferential recess which is designed as a circumferential groove 19
  • the receiver 12 in turn has a peripheral on its outer circumference projection, which is designed as a sleeve 20 on.
  • the sleeve 20 is inserted into the groove 19 and therefore is in mutual engagement with this. Since the groove 19 and sleeve 20 are oriented transversely to the longitudinal extent of the opening 18, the receiver 12 is fixed because of the mutual engagement of the two against sliding out of the opening 18.
  • a battery 13 In addition to a part of the receiver 12, a battery 13, a microphone 14, and a signal processing device 15 are arranged in the housing 11.
  • a signal processing device 15 In addition to a part of the receiver 12, a battery 13, a microphone 14, and a signal processing device 15 are arranged in the housing 11.
  • a battery 13 In addition to a part of the receiver 12, a battery 13, a microphone 14, and a signal processing device 15 are arranged in the housing 11.
  • FIG. 3 is shown as a deep-ear canal hearing aid 21 executed hearing aid schematically.
  • the electronic components battery 23, microphone 24, signal processing device 25 and receiver 22 reference is again made to the preceding explanation of the prior art.
  • the receiver 22 is also only partially disposed within the housing 17, and partially outside of the housing 27 in this embodiment. However, it is not through a tongue and groove mechanism as previously explained in the opening 28th fixed. Instead, the receiver 22 is either fixed by a (slight) press fit frictionally in the opening 28, or it is glued.
  • FIG. 4 is a deep-ear canal hearing aid 31 with schematically explained as explained above outside the housing receiver in the intended use in the ear canal of a hearing aid wearer.
  • the auditory canal is formed in the distal region by the cartilaginous portion 40 and in the proximal region by the bony portion 41. In the proximal direction, it is closed by the eardrum 42.
  • the deep-ear canal hearing aid 31 is inserted into the bony ear canal section 41. Up to this section, especially the projecting from the hearing aid 31 part of the receiver is advanced.
  • the receiver has smaller dimensions than the housing of the hearing aid 31, so that it protrudes freely into the auditory canal without contact with the auditory canal wall. This positioning avoids irritation of the sensitive bony ear canal section 41 due to contact with the hearing device 31 or receiver. At the same time, positioning is achieved deep in the ear canal.
  • the invention relates to a deep-ear canal hearing instrument, in particular a hearing aid, for wearing deep in the ear canal of a user.
  • the object of the invention is to provide a deep-ear canal hearing instrument that is inexpensive to manufacture and use, which has a small size, and comfortable deep in the ear canal, especially in the bony part of the ear canal is to be worn.
  • the invention achieves this object by means of a hearing instrument having a housing (17, 17), a signal processing device (15, 25), and a receiver (12, 22).
  • the signal processing device (15,25) is arranged in the housing (17,27).
  • the receiver (12,22) is only partially in the housing (17,27) and partly outside of the housing (17,27) arranged.
  • the housing (17,27) can be made smaller overall. In the area in which the receiver (12,22) outside the housing (17,27) is arranged, eliminates the double wall in the form of the receiver wall on the one hand and the housing wall on the other hand, which also helps to reduce the size.
