  • the receiver housing is surrounded by an expandable material, which may be expanded against the walls of the canal.
  • the insertion members of the ear piece prefferably be replaced at certain intervals. Typically, only those parts which come into contact with the ear canal are replaced and the electronics (i.e., the receiver or receiver module) are returned into the canal. It is quite difficult and cumbersome to refurbish currently available state of the art devices and it is therefore desirable to render the refurbishment, and even the original assembly, less complicated and more effi ⁇ cient .

  • the inflatable ear mold (IEM) must be filled with a fluid (air or other gas, liquid) to assure the tight fit in the ear canal. Since the IEM must be replaceable, there is a need for a clever connection between the fluid source (e.g. a pump) and the IEM. Also, the handling and normal operation of such ear molds is a problem, because connecting two parts in a fluid-tight manner normally requires a special alignment of the two parts. This is even more critical at the very small dimensions which are of primary interest here.

Abstract

L'invention concerne un écouteur (4) qui est formé pour être introduit et placé dans un canal auditif externe (2). L'écouteur comporte un ballon gonflable (9) qui peut être gonflé et dégonflé sélectivement. Quand le ballon est gonflé, il se dilate et vient se loger contre les parois du conduit auditif (2). À l'état dégonflé, il peut être retiré du conduit auditif (2). L'écouteur comporte un module récepteur (5) avec un générateur de son (12) et une connexion avec un dispositif extérieur (appareil auditif, lecteur de MP3, téléphone portable par exemple). Les ondes sonores produites dans le module de récepteur sont guidées vers le tympan (3) par un support (6) qui tient aussi le ballon (9). Dans un autre mode de réalisation, l'écouteur (4) conduit simplement les ondes sonores qui sont générées par un dispositif externe tel qu'un appareil auditif de type « contour d'oreille ». Un module de pompe à air (7) est fourni pour gonfler, ou dégonfler sélectivement, le ballon (9). Lorsque le porte-ballon (6) est connecté au module récepteur (5), une connexion automatique est formée entre l'intérieur du ballon (9) et le module de pompe à air (7).
