Definitions

  • the present invention refers to a receiver module for a hearing device, to a hearing device, such as a behind-the-ear (BTE) hearing aid, or a receiver-in-the-ear (RITE) being equipped with the receiver module and to an earpiece of a hearing device comprising the receiver module.
  • BTE behind-the-ear
  • RITE receiver-in-the-ear
  • a conventional hearing device or hearing aid which is, for example, disclosed in document US 2005/0244026, comprises a flexible earpiece to be inserted into the outer part of the ear canal of a user for wearing the hearing aid, and the flexible earpiece is connected to a BTE device through a connecting tubular element.
  • the flexible earpiece may comprise a receiver, i.e. a hearing aid speaker, which is mounted on the earpiece so as to inject sound into the user's ear canal (re- DC-in-the-ear (RITE) hearing aid) as well as a vent.
  • the BTE element of the hearing aid comprises the receiver, the sound is injected into the tubular connector communicating the sound to the earpiece arranged in the user's ear canal.
  • document US 5 606 621 discloses a hybrid BTE and a CIC (com- pletely-in-the-canal) hearing aid, wherein the earpiece is implemented as a CIC element and placed into the user's ear canal in such a manner so as to touch the bony region of the ear canal.
  • the CIC element deep into the bony region of the ear canal occlusion effect may be avoided while a high gain still can be maintained since sound communicated through the tissue into the ear canal (instead of from ear opening) may freely escape the ear canal.
  • reference US 2004/0010181 discloses a further hybrid BTE/CIC hearing aid which comprises a connector for communicating the process sound sig- nals from BTE element to a speaker in the CIC part.
  • the connector is detachably connected to either the BTE or CIC part and is designed to be inserted into the ear canal so deep as to touch the bony part of the ear canal.
  • the connector therefore must be sufficiently rigid to allow the connector to be used to insert and remove the CIC element from the ear canal of the user.
  • a hearing aid having the receiver being arranged in the ear (RITE hearing aid) is known for good sound quality since a receiver tube for carrying the sound from a receiver behind the ear and into the ear canal is not necessary.
  • RITE hearing aid only an electric wiring is used for communicating electrical signals representing the sound signals which are picked up by the microphone to the receiver module, which isinserted into the ear canal of the user.
  • a RITE hearing aid has only one microphone for picking up sound signals surrounding the user and this microphone is located at the receiver module, that is, the microphone is arranged in the user's ear canal. In this way the microphone will point outwards from the ear canal in order to pick up the sound signals from the outside.
  • the advantage is to preserve natural directional cues due to the microphone position at the natural sound entrance of the ear canal. Only one microphone is used and therefore the usual subtractive directionality provided from two omni-directional microphones is not to be used, and this has advantages such as reduced microphone noise. Instead, spatial cues will help people having mild hearing loss in getting better speech under- standing.
  • an adaptation to the acoustical conditions of the user's ear canal is required. This will facilitate the achievement of an acoustical impression for the user, wearing the hearing device, which is as natural as possible while compensating the user's hearing loss.

  • the receiver module is adapted for insertion into a canal element.
  • the assembly of receiver module and canal element is placeable in a user's ear canal.
  • the hearing device further comprises a circuit module which is electrically connected to the receiver module by a connector.
  • the receiver module comprises a distal end exposed to the closed portion of the user's ear canal and a sensor is arranged at the receiver module and the sensor is adapted for sensing acoustical conditions, such as sound pressure in the closed portion of the user's ear canal and for generating corresponding electrical signals. Further, the connector for communicating the electrical signals to the circuit module is established, such that the processing of the signals may be performed in the circuit module. Fastening elements adapted for removably fixing the receiver module in the canal element are also provided.
  • the specific receiver module facilitates a proper setting and calibration of the hearing device, since on the one hand the sensor is provided at the receiver module and adapted to be exposed to the user's ear canal and on the other hand a mechanical structure of the receiver module is provided which allows an easy replacement of an ordinary receiver module for regular daily use with the specific receiver module for measuring and calibration.
  • the easy replacement of the two receiver modules: the one for regular daily use, and the one for calibration purposes, is possible as they have basically the same size and almost the same acoustical and mechanical properties. This leads to a time-saving testing and setting (calibration) process of the hearing device, and the user can be sure that the setting of the hearing device is made the best way based on the real (natural) sound situation in the ear canal.
  • the fastening elements of the receiver module may be adapted for engagement with a snapping element of the canal element.
  • the snapping element allows the placement of the receiver modules in a secure manner in the canal element, and further the snapping element leaves the hearing care professional in no doubt that the receiver module and the canal element are correctly positioned in relation to each other.
  • the fastening elements of the receiver module may further be adapted for engagement with a canal element comprising compliant parts of a flexible dome.
  • a compliant part may comprise hollow pipe part arranged centrally of dome elements made of flexible material.
  • the fastening elements may be shaped as circumferential beads on the receiver module placed close to the distal and the proximal end thereof, such that the pipe element is to fit in between the beads.

  • the respective sensors 40 and 50 are located at a predetermined position on or at the respective receiver modules 21 or 21T.
  • the present invention is, of course, not limited to the arrangement shown in Figs. 1 - 5, and any other suitable arrangement of the sensors 40 and 50, respectively, in conjunction with the corresponding receiver modules 21 or 21 T is possible without affecting the function of the components of the hearing device 10 according to the present invention and without giving up the advantages obtained.

Abstract

La présente invention porte sur un module récepteur (21 T) d'un dispositif auditif (10). Le module récepteur est conçu pour une insertion dans un élément de canal (22) du dispositif auditif qui comprend en outre un module de circuit (11). L'élément de canal est destiné à être placé dans le canal de l'oreille d'un utilisateur et définit une partie fermée du canal de l'oreille de l'utilisateur entre l'élément de canal et la membrane du tympan de l'utilisateur. Le module récepteur comprend un capteur (50) agencé à une extrémité distale (25) du module récepteur pour détecter des conditions acoustiques (signaux sonores) dans la partie fermée du canal de l'oreille de l'utilisateur et générer des signaux de détection correspondants qui sont soumis à un traitement prédéterminé par ledit module de circuit, un connecteur (12) pour communiquer lesdits signaux de détection audit module de circuit, et des éléments de fixation (24, 27) pour fixer de façon amovible ledit module récepteur dans ledit élément de canal.
