Definitions

  • the present disclosure relates to caps, also termed dome, flexible insert mount, ear tip or acoustic coupler, for hearing devices configured to be inserted in a user's ear canal. More particularly, the disclosure relates to an improved wax filter for the caps.
  • the ear canal produces wax (earwax), also known as cerumen, which serves as a natural lubricant for the ear canal.
  • cerumen also known as cerumen
  • hearing devices are in close contact with the user's ear, and thereby, hearing devices are exposed to the wax.
  • the wax enters through an opening such as a sound outlet of the hearing device and advances through an interior channel in the cap.
  • wax may be pressed into the cap until it reaches a wax filter right in front of an output unit of the hearing device.
  • the wax is trapped inside the hearing device.
  • the wax accumulates inside the cap and clogs the channel and/or the wax filter in front of the output unit. Consequently, this leads to a deterioration of the sound output such as a reduced volume or a muffled tone.
  • users may consider hearing devices as malfunctioning due to the deterioration of sound or even return them for repair.
  • the caps are clogged by wax and the function can be re-established by replacing the wax filter in front of the output unit.
  • a cap for a hearing device wherein the cap is configured to be inserted in the ear canal of a user.
  • the cap includes a dome-shaped part comprising a channel for receiving an acoustic signal from an output unit at a sound inlet and an opening connected to said channel, a first wax filtering element comprising a sound outlet, and a second wax filtering element.
  • the first wax filtering element protrudes from the dome-shaped part and is arranged to bridge the opening of the dome-shaped part.
  • the second wax filtering element at least partially protrudes from the dome-shaped part and/or from the first wax filtering element into a space between the first wax filtering element and the dome-shaped part.
  • the first wax filtering element and the second wax filtering element define a sound path from the channel to the sound outlet.
  • the first wax filtering element has an arched shape and protrudes from the dome-shaped part such as to form a bridge over the opening of the dome-shaped part. Thereby, the first wax filtering element protects the opening of the dome-shaped part and prevents wax from easily entering into the channel.
  • the second wax filtering element protrudes from the dome-shaped part and/or from the first wax filtering element into a space between the first wax filtering element and the dome shaped part.
  • the second wax filtering element provides a barrier between the opening and the sound outlet and prevents particles of wax that might fit below the arched shape of the first wax filtering element from entering into the channel.
  • the second wax filtering element increases the surface area and, thereby, supports retaining wax by providing additional surface area for adhesion of the wax.
  • the second wax filtering element may be formed in any shape, and can have, for example, a bar shape, a plate shape, or a three-dimensional shape.
  • the second wax filtering element may be implemented as a brush comprising fibers or filaments protruding from the dome-shaped part and/or from the first wax filtering element.
  • the second wax filtering element may be arranged so as to protrude through the opening of the dome-shaped part into the channel.
  • the cap may be provided with another second wax filtering element or a plurality of second wax filtering elements.
  • the first wax filtering element and the second wax filtering element together define a sound path from the channel to the sound outlet. Thereby, sound is guided from the channel along the second wax filtering element, and subsequently along the first wax filtering element to the sound outlet. Wax, which enters at the sound outlet, advances through the cap in the opposite direction of the sound.
  • the second wax filtering element may be arranged so as to divide a space between the first wax filtering element and the dome-shaped part into at least two sub-spaces.
  • the sub-spaces are disconnected from each other and thereby wax, which has entered into one sub-space, cannot advance from this sub-space to another sub-space directly. This prevents other sub-spaces from becoming clogged by wax, which has already entered into one sub-space, and thereby improves the robustness of the cap against clogging.
  • At least a part of the sound path defined by the second wax filtering element may be arranged in a direction different from that of the sound path defined by the first wax filtering element.
  • a labyrinth structure is created. This labyrinth structure is easily passed through by sound, but is much harder to be passed through by wax.
  • the sound path defined by the first wax filtering element and the second wax filtering element may also include several bends and changes in direction to further enhance the wax retention properties.
  • At least a part of the sound path defined by the second wax filtering element may be arranged in more than one direction so that one sub-space defines a first sound path direction and another sub-space defines a second sound path direction, which is different from the first sound path direction.
  • the first wax filtering element may at least partially cover the second wax filtering element. Accordingly, in a top view, the first wax filtering element is arranged above the second wax filtering element so that the second wax filtering element is at least partially covered and protected by the first wax filtering element. However, a part of the second wax filtering element may not be covered and may protrude through the sound outlet to the outside of the cap.
  • the second wax filtering element may comprise a portion that connects the first wax filtering element and the dome-shaped part across the sound outlet. This allows for reducing the opening cross-section of the sound outlet and, thereby, prevents particles of wax that might fit below the arched shape of the first wax filtering element from entering into the space between the first wax filtering element and the dome-shaped part. Despite the reduced opening cross-section, sound can easily pass through, whereas particles of wax are prevented from getting stuck in the cap.
  • the second wax filtering element may comprise a plurality of through holes so that the second wax filtering element has a grid structure.
  • the grid structure provides a reduced cross-section and allows only particles of wax, which are smaller than the through holes, to pass through. Thereby, the wax filtering capability is further improved.
  • the plurality of through holes may each have a polygonal shape.
  • the polygonal shape may be a triangular shape, a rectangular shape, or any other polygonal form.
  • the polygonal shape allows an arrangement of the plurality of through holes such that a portion of the second wax filtering element between two adjacent through holes has a simple structure such as a bar shape.
  • the first wax filtering element and the second wax filtering element may be integrally formed. Accordingly, both wax filtering elements may be manufactured in one step and an additional step of integrating the second wax filtering is not necessary.
  • the cap may comprise a plurality of holes arranged on the outer peripheral surface of the dome-shaped part. This allows ambient air to circulate into the inner side of the ear canal through the plurality of holes and prevents the cap from completely sealing the inner ear canal.
  • the cap may be made of at least two flexible materials, wherein an inner core part is made of a harder material than an outer part of the cap.
  • the outer part of the cap is made of a relatively soft and flexible material. Thereby, the outer part of the cap easily allows elastic deformation and ensures adaptability to the individual shape of the user's ear canal. Accordingly, a high comfort during use is achieved.
  • the inner core part enables a connection of the cap to the output unit, and by being made of a flexible material, the inner core part can elastically deform when being attached to the output unit. Accordingly, a simple connection between the cap and the output unit is achieved.
  • using a relatively hard but flexible material for the inner core part ensures a tight fit and prevents the cap from easily coming off the output unit, especially during use.
  • the cap may further comprise a third wax filtering element.
  • the third wax filtering element provides additional protection against wax entering through the cap and possibly damaging the output unit.
  • the third wax filtering element is provided in a cavity of the dome-shaped part and is connected to the sound inlet. Thereby, the third wax filtering element is arranged so that wax entering through the sound outlet first must pass the first wax filtering element and the second wax filtering element until it can reach the third wax filtering element.
  • the third wax filtering element is reliably accommodated inside the dome-shaped part, so that accidental coming off of the third wax filtering element is prevented, especially during use.
  • the third wax filtering element may be replaceable. Accordingly, the third wax filtering element can be removed and exchanged with a new one, in case it is clogged with wax. By replacing only the third wax filtering element, the cap itself may be reused several times. This allows for a reduction of the waste amount occurring during use of the hearing device.
  • the third wax filtering element may be adapted to be at least partly permeable for sound transmission and to be at least partly impermeable for material. Thereby, wax from the user's ear canal is prevented from passing through the third wax filtering element, whereas sound can pass through the third wax filtering element so that sound from the output unit can reach into the ear canal of the user.
  • a hearing device comprising the cap, which is adapted for being positioned in the user's ear canal.
  • the hearing aid may e.g. be a behind-the-ear type, an in-the-ear type or a receiver-in-the-ear type.
  • the electronic hardware may include microprocessors, microcontrollers, digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic devices (PLDs), gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure.
  • Computer program shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.
  • a hearing device may include a hearing aid that is adapted to improve or augment the hearing capability of a user by receiving an acoustic signal from a user's surroundings, generating a corresponding audio signal, possibly modifying the audio signal and providing the possibly modified audio signal as an audible signal to at least one of the user's ears.
  • the "hearing device” may further refer to a device such as an earphone or a headset adapted to receive an audio signal electronically, possibly modifying the audio signal and providing the possibly modified audio signals as an audible signal to at least one of the user's ears.

  • the hearing device is adapted to be worn in any known way. This may include i) arranging a unit of the hearing device behind the ear with a tube leading air-borne acoustic signals into the ear canal or with a receiver/ loudspeaker arranged close to or in the ear canal such as in a Behind-the-Ear type hearing aid, and/ or ii) arranging the hearing device entirely or partly in the pinna and/ or in the ear canal of the user such as in a In-the-Ear type hearing aid or In-the-Canal/ Completely-in-Canal type hearing aid, or iii) arranging a unit of the hearing device attached to a fixture implanted into the skull bone such as in Bone Anchored Hearing Aid or Cochlear Implant, or iv) arranging a unit of the hearing device as an entirely or partly implanted unit such as in Bone Anchored Hearing Aid or Cochlear Implant.
  • a “hearing system” refers to a system comprising one or two hearing devices
  • a “binaural hearing system” refers to a system comprising two hearing devices where the devices are adapted to cooperatively provide audible signals to both of the user's ears.
  • the hearing system or binaural hearing system may further include auxiliary device(s) that communicates with at least one hearing device, the auxiliary device affecting the operation of the hearing devices and/or benefitting from the functioning of the hearing devices.
  • a wired or wireless communication link between the at least one hearing device and the auxiliary device is established that allows for exchanging information (e.g. control and status signals, possibly audio signals) between the at least one hearing device and the auxiliary device.
  • Such auxiliary devices may include at least one of remote controls, remote microphones, audio gateway devices, mobile phones, public-address systems, car audio systems or music players or a combination thereof.
  • the audio gateway is adapted to receive a multitude of audio signals such as from an entertainment device like a TV or a music player, a telephone apparatus like a mobile telephone or a computer, a PC.
  • the audio gateway is further adapted to select and/or combine an appropriate one of the received audio signals (or combination of signals) for transmission to the at least one hearing device.
  • the remote control is adapted to control functionality and operation of the at least one hearing devices.
  • the function of the remote control may be implemented in a SmartPhone or other electronic device, the SmartPhone/ electronic device possibly running an application that controls functionality of the at least one hearing device.
  • a hearing device in general, includes i) an input unit such as a microphone for receiving an acoustic signal from a user's surroundings and providing a corresponding input audio signal, and/or ii) a receiving unit for electronically receiving an input audio signal.
  • the hearing device further includes a signal processing unit for processing the input audio signal and an output unit for providing an audible signal to the user in dependence on the processed audio signal.
  • the input unit may include multiple input microphones, e.g. for providing direction-dependent audio signal processing.
  • Such directional microphone system is adapted to enhance a target acoustic source among a multitude of acoustic sources in the user's environment.

  • FIG. 1A illustrates, in a perspective view, a cap 1 for a hearing device according to an aspect of the disclosure.
  • the cap 1 has a dome-shaped part 2, which has a curved outer peripheral surface. The curvature is convex so that the dome-shaped part 2 has a substantially hemispherical shape. Thereby, the apex of the dome-shaped part 2 is located at a tip end 9 of the dome-shaped part 2.
