Definitions

  • the present invention relates to an electroacoustic transducer for sound generation and / or amplification for the ear.
  • Electroacoustic transducers for sound conversion and / or amplification for the ear are known, for example, in the form of hearing aids or hearing aids that are on the market. Such hearing aids have a microphone for recording the acoustic energy and for converting them into electrical signals, which are amplified in an amplifier and then converted back into sound signals, so that the sound events are raised to a higher sound level and thus still belong to the hearing impaired can be.
  • One type of this hearing aid is the pocket hearing aid in which the receiver via a flexible line with the actual device and the supply unit is connected to a battery or e'twa 'a rechargeable accumulator. The listener is inserted into the ear.
  • Such pocket hearing aids are cosmetically unsatisfactory, since the connecting line between the earphone plugged into the ear and the device which the user wears on the body in the outer clothing is visible to everyone. In addition, it is inconvenient and inconvenient for the user to move the handset with the connecting line from a pocket of the outer clothing to the ear, every time he dresses.
  • head-hearing devices are also known, in which all components are accommodated in a single housing.
  • These head devices are worn behind the ear as so-called behind-the-ear hearing aids, in the arms of glasses as so-called hearing glasses or in the auricle and in the external auditory canal as so-called in-the-ear hearing aids.
  • these embodiments of hearing aids have a more compact structure, they remain unsatisfactory for cosmetic reasons. With none of these devices, it is possible to hide that a hearing aid is worn or used, because the devices are still visible and stand out despite all efforts.
  • the invention is therefore based on the task of creating an electroacoustic transducer for sound generation and / or amplification for the ear which is not visible to third parties.
  • the transducer is implanted in a bone close to the ear.
  • the bone provided for receiving the transducer is surgically provided with a bone cavity, the miniaturized transducer is inserted, and the surgical field is then completely closed again. The transducer is then invisible under the skin.
  • the transducer is preferably implanted in the bone behind the ear cup, the so-called mastoid bone.
  • the implanted transducer can be connected via an electrical line to a power supply unit arranged outside the bone.
  • the power supply unit can be, for example, a battery or an accumulator that is rechargeable.
  • the power supply unit is also implanted at one point on the head or body and is therefore arranged so that it is invisible to third parties.
  • Batteries and accumulators “have such small dimensions nowadays that they can be implanted under the skin, for example, near the ears, somewhat above the hairline.
  • the power supply unit is implanted in the bone together with the transducer.
  • the power supply unit and the converter are preferably a unitary component, so that the implantation of this component also includes the implantation of the power supply unit.
  • the transducer has a connection piece which projects outwards from the implanted transducer through the bone.
  • This neck or extension can, for example, protrude somewhat from the skin in the area of the auricle, for example under the hairline.
  • the converter can be adjusted or adjusted via the nozzle.
  • a corresponding button can be provided on the outer end of the neck.
  • the adjustment can include a volume setting but also other setting options, such as a sound aperture setting for changing the sound characteristic and / or the switching on and off.
  • the line connecting the transducer to the supply unit can be guided over or through this connector.
  • a particularly advantageous embodiment of the invention consists in the fact that the supply unit implanted together with the transducer can be charged and that the charging takes place via the connecting piece.
  • a rechargeable supply unit which contains, for example, an accumulator, is normally sufficient for 24 to 48 hour operation.
  • the charging can be carried out by means of a charging device over the nozzle, either during sleep or in the evening while reading or watching TV.
  • the sound is emitted through a sound exit channel, which extends from the implanted electroacoustic transducer through the auditory canal wall into the auditory canal. That way again ensures that no externally visible objects or arrangements are visible.
  • the transducer has a bone transmission vibrator.
  • the electrical signals which may be amplified, are not converted into acoustic waves which are transmitted via the air, but into vibrations which are transmitted by the bone transmission vibrator and propagated as structure-borne noise.
  • mount the bone transmission vibrator directly on the labyrinth block.
  • An alternative option is to attach the bone transfer vibrator to the bony outer shell of the snail. In this way an optimal transmission of the sound is achieved.
  • This embodiment of the invention is also particularly advantageous because acoustic feedback, which is expressed by strong whistling, is avoided with certainty.
  • the transducer is a hearing amplification device for artificial sound amplification.
  • the hearing enhancement device has a microphone for recording and converting the acoustic energy into an electrical variable.
  • a particularly advantageous development of the invention is characterized by a sound entry channel, which extends from an outer region of the auditory canal through the auditory canal wall to the microphone of the hearing amplification device. Since the entry of the sound entry channel lies in the auditory canal, it is not visible from the outside, so that a further cosmetic safety for the patient can be created.
  • a very advantageous embodiment of the electroacoustic transducer according to the invention is that the transducer is an electrical receiver which receives electrical signals and converts the electrical signals into acoustic signals.
  • High-frequency receivers for example radio receivers t , etc., are preferably used here.
  • the use of the electroacoustic transducer according to the invention as an electrical receiver is very advantageous, for example, for teaching and addressing the hearing impaired, without the need for an electrical connection. Again, it is ensured that the electrical receiver is completely invisible due to the implantation.
  • the electroacoustic transducer designed in this way as an electrical receiver can, however, also be used for a wide variety of other tasks, for example for controlling and instructing people without third parties gaining knowledge of it.
  • the receiving antenna of the electrical receiver is implanted in the bone together with the latter.
  • An alternative possibility is to arrange the receiving antenna in the socket. It is also possible that the receiving antenna protrudes outwards through the connection piece if this should be necessary for the reception conditions.
  • a particularly advantageous embodiment consists in that the receiving antenna projecting outward through the connecting piece is connected to a spectacle frame.
  • the spectacle frame can be made of a metal and at the same time serve as part of the receiving antenna, so that the reception properties of the antenna can be improved without the receiving antenna itself appearing.
  • the electroacoustic transducer is a so-called tinnitus masker.
  • Such maskers are devices that are worn like hearing aids and produce a sound. These maskers are used in people who suffer from ear noises (tinnitus). Such maskers overlay the subjectively heard noises with background music or a background tone, which have humming, sounding, rushing, whistling and hissing sound character and can also be very complex. Through the sound production of the masker these - noises are "masked", since such tones are perceived more pleasantly than the ear noise itself. Due to the possibility of adjusting and adjusting the masker with regard to volume, sound character composition, frequency etc. via the nozzle, one can be readjusted at any time Adjustment of the generated tones possible.
  • the electroacoustic transducer is an electrical transmitter that emits electrical signals. In this way it is possible to carry and operate transmitters unnoticed by outsiders.
  • the transmitting antenna can be implanted together with the transmitter in the bone, arranged in the socket or protrude outwardly through the socket, with the possibility being provided by to connect the connecting piece projecting outwards with an eyeglass frame which is enlarged and optimized transmission antenna can serve.
  • the power supply unit it is possible to mount the power supply unit on a skin area behind the auricle, so that it can be reached and replaced at any time from the outside without the need for a surgical intervention, however small, to replace the unit . Since the unit is located behind the auricle and is extremely small these days, it is also not visible to outsiders.
  • the transducer (7) is arranged directly under the skin on the bone. This is also advantageously done behind the ear. Due to the progress of microelectronics today, the transducers can be made so small that they can practically be attached and attached to the bone as thin disks under the skin.
  • Embodiments also consist of generally implanting electronic micro devices, for example microchips, microcomputers and / or measuring devices in the body and in particular in a bone, advantageously close to the ear.
  • the figure shows a partial cross section through the human ear.
  • the auditory canal 2 leads from the ear cup 1 to the eardrum 3.
  • Above the auditory canal 2 is the cranial bone 4, the area of which adjoining the auditory canal 2 is the so-called mastoid 5.
  • a bone cavity 6 is operatively formed in the mastoid 5, in which the electrical troacoustic transducer 7 is in the form of a hearing aid.
  • a connecting piece 8 protrudes through the skull bone 4 and ends behind the ear cup 1 directly on the scalp.
  • At the outer end of the connector 8 there may be a button 9 for adjusting the amplifier.
  • a sound entry channel 10 is provided which extends from the sound entry opening 11 to a microphone of the sound reinforcement device 7. Through this sound entry channel 10, the sound reaches the microphone, where it is converted into an electrical signal, which is amplified in an amplifier circuit of the amplification device 7. The amplified signal is then converted into a sound signal and reaches the ear canal and the eardrum 3 via a sound exit channel 12.
  • the entire hearing enhancement device 7 is implanted completely invisibly in a bone area of the cranial bone.
  • the sound inlet duct 10 and the sound inlet opening 11 are not visible from the outside, and neither is the sound outlet duct 12, so that the entire system does not appear in any way.

Abstract

Un transducteur électro-acoustique, par exemple un appareil pour sourds ou un récepteur de signaux de haute fréquence, se loge entièrement dans une cavité chirurgicalement ménagée dans les os adjacents à l'oreille, ce qui fait que l'appareil est complètement invisible. De préférence, un accumulateur rechargeable est implanté en même temps que le transducteur électro-acoustique. Le transducteur peut comprendre un tube au moyen duquel il peut régler l'amplificateur, effectuer d'autres réglages éventuels ou charger l'unité d'alimentation, par exemple.
