Definitions

  • the present disclosure relates to a hearing device comprising an earmould.
  • the hearing device further comprises a receiver housing arranged at least partly within the earmould, and a supporting structure configured to hold the receiver housing in place within the earmould, wherein at least part of the supporting structure comprises a material that is softer than the material used to make the middle part of the earmould.
  • Some hearing devices have an earmould that is placed at least partly within an ear canal of the user of the hearing device. This allows the receiver, i.e. speaker unit, within the earmould to be brought to sit relatively close to the tympanic membrane of the ear canal during use.
  • Wearing an earmould can be discomforting for the user for a variety of reasons such as occlusion and a poor fit of the earmould within the user's ear canal.
  • a hearing device comprising an earmould.
  • the earmould comprises a front end, a rear end opposite the front end, and a middle part arranged in-between the front and a rear end.
  • the front end comprises a front opening
  • the rear end comprises a rear opening.
  • the earmould is configured for the front end to be positioned facing a tympanic membrane of the user during use.
  • the hearing device further comprises a receiver housing arranged at least partly within the earmould, and a supporting structure configured to hold the receiver housing in place within the earmould.
  • At least part of the supporting structure comprises a material that is softer than the material used to make the middle part of the earmould.
  • the entire supporting structure is made from a material that is softer than the material used to make the middle part of the earmould.
  • the earmould, or at least the middle part of the earmould may be a hard earmould comprising, or being made entirely of, a material having a measured hardness of 60-100 shore D, such as of 70-90 shore D, such as of 75-85 shore D.
  • the earmould, or at least the middle part of the earmould may be made using 3D printing technology.
  • the earmould, or at least the middle part of the earmould may be made of a photopolymer resin such as a DLP (Digital light processing) resin.
  • the earmould is a hard shell earmould.
  • Hard shell earmoulds are commonly used for making custom earmoulds, i.e. earmoulds where at least part of it has been shaped to conform to a particular user's ear canal. Making an earmould as a hard shell makes the earmould more comfortable for the user and the earmould is more likely to stay in place in a user's ear canal compared to a soft earmould.
  • all or part of the earmould is configured to at least partially conform to at least part of the ear canal of the user.
  • the middle part of the earmould is made from an acrylic.
  • the supporting structure comprises silicone rubber, TPE, TPA, EPDM and/or LSR.
  • the supporting structure comprises a flexible material configured to stretch so as to accommodate the receiver housing during insertion of the receiver housing within the earmould and to hold the receiver housing in place after insertion. Having a supporting structure made from a softer material than that of the earmould allows for compensation of deviations during manufacture, such as low fidelity print resolution, i.e. for the receiver housing to be inserted in an earmould, which is not itself flexible enough to provide give during insertion and where even a small deviation during manufacture can make it difficult or impossible to insert the receiver housing, especially if the receiver housing is to be removable.
  • the receiver housing may be removably arranged within the earmould.
  • the supporting structure is configured such that the receiver housing is removably arranged within the earmould.
  • An exchangeable receiver allows the receiver to be exchanged if needed or desired. For example, the receiver may be replaced if it is defective, or as part of an exchange or upgrade of part of the hearing device. Having a removable receiver in the hearing device may extend the usable lifetime of the hearing device and save cost. Further, materials may be saved as the manufacturer may avoid a replacement of the entire earmould and instead replace only parts of the hearing device such as the receiver and/or one or more filters thus making the production and maintenance of the hearing device more sustainable.
  • the user may be able to keep an earmould that fit well even though part of the hearing device such as the receiver housing needed to be replaced. Additionally, as earmoulds can be difficult to fit for a user, the earmould may be part exchanged.
  • the hearing device comprises electronic components, which may be comprised e.g. in the receiver housing and/or within the earmould.
  • the hearing device may comprise electronic components and circuits that create, process, and/or cancel audible sound, such as electronic components that act to provide hearing compensation.
  • the receiver housing may comprise a receiver.
  • the receiver housing may comprise electronic components.
  • a receiver in an earmould of a hearing device is configured such that sound produced by the receiver travels through the front opening of the earmould. In this way, the receiver is able to deliver sound to the ear canal of the user.
  • the front opening may comprise a front filter configured to hinder contaminants from entering the earmould through the front opening.
  • Contaminants may be e.g. humidity, dirt, hair, oily substances (such as ear wax), i.e. the front filter may be a cerumen grid.
  • the front filter may be removable such that it can be replaced if needed.
  • the supporting structure may be arranged in a variety of ways to achieve the purpose of holding the receiver housing in place within the earmould.
  • the supporting structure comprises a plurality of supporting structures.
  • the supporting structure may be configured to allow the receiver housing to move, such as when the user talks or chews, which provides increased comfort for the user of the hearing device.
  • At least part of the supporting structure extends from an inside wall of the earmould.
  • the supporting structure comprises a fixation tip attached to the front end of the earmould.
  • the fixation tip may be part of the front opening.
  • the fixation tip may be configured to hold the receiver housing in place within the earmould.
  • the fixation tip comprises the front opening.
  • a fixation tip may be made custom for a user or may be provided as a standard part in a variety of sizes.
  • the receiver housing and/or an active vent coupled to the receiver housing may be held in place at the front opening.
  • the earmould further comprises a flexible and resilient element that is configured to cushion the receiver housing against an inside wall of the earmould.
  • the flexible and resilient element may comprise a foam material. The cushioning by the flexible and resilient element allows the receiver housing to move, such as when the user talks or chews, which provides increased comfort for the user of the hearing device.
  • the at least part of the supporting structure which is comprised in the front opening, may comprise a material that is softer than that of the middle part, and the receiver housing and/or an active vent coupled to the receiver housing may be removably attached to the supporting structure at the front opening.
  • An active vent comprises a valve and is configured to have an open state and a closed state, wherein the valve, in the open state, provides a fluid connection through a sound passage, and wherein the valve, in the closed state, hinders fluid connection through the sound passage.
  • a sound passage extends between the front opening and the rear end, and is configured to allow for fluid connection between the front opening and an outside of the earmould.
  • An active valve will form at least part of the sound passage.
  • the sound passage will thus allow fluid, such as air or liquids, to flow between the front opening and an outside of the ear canal during use of the hearing device.
  • fluid such as air
  • the open state fluid, such as air
  • the closed state the passage of fluid via the sound passage is blocked.
  • the active vent may be configured to being controlled by a vent control arrangement comprised in the hearing device.
  • An active vent may be positioned in-between the receiver and the front opening.
  • An active vent may be positioned such that sound produced by the receiver passes through the vent.

  • coupled is meant that the active vent and the receiver housing are physically coupled, for example as an active vent receiver.
  • the active vent is held in place within the earmould by at least part of the supporting structure. If the active vent is coupled to the receiver housing, holding the active vent in place within the earmould will hold the receiver housing in place within the earmould.
  • the receiver or receiver housing comprises a wired connection, which is configured to connect the receiver electronics with other parts of the hearing device, such as with a Behind-the-ear (BTE) part.
  • the supporting structure is configured to at least partially surround the wired connection.
  • the part of the receiver housing from where the wired connection extends may comprise a structure, which is configured to connect with the supporting structure.

  • At least part of the supporting structure is arranged at the rear end of the earmould.
  • the receiver housing takes up a significant part of the available space within the earmould.
  • some receiver housings have a comparatively large spout diameter, i.e. a comparatively large diameter of the structure, where sound exits the receiver housing.
  • active vent receivers which have an active vent comprised in the receiver housing, may have a larger spout diameter. Design of an earmould is challenged by the available space within the ear canal of the user, and if the overall dimensions of the earmould grow this may become a problem.
  • an increase in overall dimension of an earmould may reduce the insertion depth of the earmould and also how well it can fit inside the ear canal.
  • Having the supporting structure at the rear end or primarily at the rear end of the earmould may save space at the front of the earmould compared to fixation of the receiver housing at the front end. It may be advantageous to combine a soft material at the front opening providing an acoustic seal between the receiver housing and the earmould with a supporting structure at the middle part or the rear end providing the necessary force to hold the receiver housing in place.
  • the earmould further comprises a faceplate that is attached to the rear end of the earmould.
  • the faceplate may be configured to allow ambient sound from outside the ear canal of the user to pass through it.
  • the faceplate may be removably attached to the earmould.

  • the supporting structure is configured to suspend the receiver housing within the earmould.
  • the supporting structure may be configured to allow for the receiver housing to have some freedom of movement within the earmould. This will allow the receiver housing to move in response to forces acting on the earmould such as during movement of the user's jaws and may also dampen any vibrations from the receiver.
  • the receiver housing may be arranged within the earmould in such a way that at least part of or most of the outer surface of the receiver housing is not in contact with a supporting structure.
  • the receiver housing may be coupled to the earmould only at the front opening, possibly via an active vent.
