Definitions

  • the present invention relates to a method of manufacturing a receiver-in-canal assembly comprising an elongated tube. Furthermore, the present invention relates to the receiver-in-canal assembly.
  • receiver-in-canal assemblies are manufactured in different sizes and shapes to fit different users. Furthermore, the tubes are manufactured in different shapes dependent on whether the receiver-in-canal assembly is for the left ear or for the right ear of a user. Consequently, the number of configurations has to be multiplied with two, thus doubling the number of different configurations.
  • the invention provides a method of manufacturing a receiver-in-canal assembly, the method comprising the steps of:
  • the method may further comprise a step of providing a receiver housing configured to be positioned in or at the ear canal of a user and being configured to comprise a receiver to output sound, and a step of attaching the receiver housing to a first end of the elongated tube.
  • a receiver housing configured to be positioned in or at the ear canal of a user.
  • the receiver housing is configured to comprise a receiver to output sound.
  • the receiver housing may comprise a front housing part and a rear housing part.
  • the receiver may be positioned in the rear housing part.
  • the receiver may be adapted to receive an electrical signal and output a corresponding audio signal.
  • an elongated tube configured for transfer of a signal.
  • the signal may be provided to the receiver housing.
  • an "elongated tube” should be understood as a hollow tube having a length being considerably longer than the diameter of the tube, such as a length being at least 5 times larger than the largest dimension of the tube in a direction perpendicular to the longitudinal axis.
  • the length of the tube may be in the range of 30-80 mm.
  • the diameter of the tube may be in the range of 0.5-2 mm.
  • the tube may be made from a plastic material, such as a polymer.
  • the provided elongated tube is straight.
  • the elongated tube may comprise at least one wire.
  • the at least one wire may be attached to the inner wall of the tube to ensure that the wire is kept in place both during the manufacturing process and during use of the hearing air.
  • the at least one wire may be moulded into the wall of the tube.
  • the tube may fulfil the function of a support structure in order to keep the receiver-in-canal assembly on the ear during its use.
  • the stiffness of the tube may be chosen to fulfil this requirement and also to protect the electrical wires inside the tube.
  • the tube material may also fulfil other requirements, such as biocompatibility, transparency, UV stability, chemical stability, and mechanical robustness/flex life and the like.
  • the tube may be made of Rilsan (as the main ingredient with other possible ingredients in low ratios), Pebax (as the main ingredient with other possible ingredients in low ratios), or a blend of the two in different percentages.
  • the tube may be formed as a two-layer tube comprising: an inner polymer layer and an outer barrier layer of a mineral-oil resistant polymer.

  • the receiver housing may be attached to a first end of the elongated tube.
  • the method comprises a step of bending the elongated tube to provide a first bent section and a step of arranging a first stiffening member at the tube to support the tube at the first bent section.
  • the first stiffening member may be made form a material being stiffer than the tube to thereby ensure that the elongated tube is not unbended to form a more or less straight tube. Alternatively or additionally, the stiffening member may due to its material thickness ensure that the elongated tube is not unbended.
  • the first stiffening member is rotated relative to the tube to adjust the receiver-in-canal assembly for a right or a left ear of a user.
  • the tube may be used for both a left and a right ear, as the tube and the stiffening member may rotate relative to each other and thus enable rotating of the tube both toward the right and the left side. This may be achieved as the opposite second end of the tube is rotated with the tube at the first stiffening member, whereby the second end may extend toward two opposite directions when rotating the tube and the stiffening member relative to each other.
  • the stiffening member may be releasably attached to the tube. It should however be understood, that the stiffening member may alternatively be fixedly attached to the tube.

  • the bent second being closest to the receiver housing will be denoted the first bent section whereas the bent section being further away from the receiver housing will be denoted the second bent section. It should however be understood, that this is a chosen term.
  • the first and second bent sections may just as well be used oppositely, and the chosen terms do not imply any limitation in this regard.

  • the shape of the first stiffening member may form the first bent section.
  • the first stiffening member may have a shape corresponding to the required shape of the first bent section.
  • the first bent section may simultaneously form the first bent section.

  • the connector housing may comprise a plug part configured for attachment to the elongated tube and a plug base configured for attachment to a behind-the-ear part of a hearing aid.
  • the behind-the-ear part may comprise electronics, controls, battery, microphone(s), and a receiver, if the receiver is not positioned in the receiver housing.
