HEARING DEVICE WITH FIXATION ARRANGEMENT

FIELD

The present disclosure relates to a hearing device having a housing configured to be arranged in the ear canal or behind the outer ear of a user. The present disclosure more particularly relates to a hearing device having an attachment arrangement attached to the housing, wherein the attachment arrangement comprises a first attachment part and a second attachment part configured to be arranged at opposing sides of the pinna of the user.

BACKGROUND

For e-health hearing devices (including hearing aids), it is often desired to arrange sensor elements (e.g. electrodes) in contact with the wearer's skin. Especially for hearing aid as behind-the-ear (BTE) and receiver-in-the-ear (RITE) types, it is difficult to ensure attachment of the sensor elements with a sufficient pressure towards the skin in order to maintain skin contact.

The prior art suggests the use of adhesives. However, this solution is expensive over time, and can lead to allergy issues (allergic reactions). Other prior art solutions apply clamps or springs. These solutions are associated to several drawbacks as they are often difficult to handle and can pinch or abrade the skin. Additionally, a range of clamp sizes must be stocked and selected by the hearing care professional.

Therefore, there is a need to provide a solution that addresses at least some of the above-mentioned problems. The present disclosure provides at least an alternative to the prior art.

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. Such audible signals may be provided in the form of an acoustic signal radiated into the user's outer ear, or an acoustic signal transferred as mechanical vibrations to the user's inner ears through bone structure of the user's head and/or through parts of middle ear of the user or electric signals transferred directly or indirectly to cochlear nerve and/or to auditory cortex of the user.

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 an In-the-Ear type hearing aid or In-the-Canal/Completely-in-Canal type hearing aid.

A “hearing system” refers to a system comprising one or two hearing devices, and 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.

In general, a hearing device 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 attraction members 10, 10′, 12, 12′ may be may be made in magnetic or magnetisable material (e.g. permanent magnets) or an electrostatic material.

A sound tube 16 extends from the housing 4 to the earmould 8. Hereby, sound generated by a receiver (not shown) arranged in the housing 4 can be transmitted into the ear canal of the user through the sound tube 16 and the earmould 8.

The housing 4 comprises a first sensor element 14 having a plate-shaped contact surface abutting the ear 6 hereby being in contact with ear 6. The housing 4 comprises a second sensor element 14′ provided with a plate-shaped contact surface abutting the ear 6 and thus being in contact with ear 6. The sensor elements 14, 14′ may be electrodes or other types of sensors configured to detect desirable signals/inputs.

FIG. 10 illustrates a schematic, cross-sectional view of a hearing device 2 according to another embodiment of the disclosure. The hearing device 2 is an ITE hearing aid 2 comprising a housing 38 arranged in the ear canal 30 of the user. An electric wire member 36 extends between the housing 38 and a first attachment part 8 arranged at one side of the outer ear 6 of the user. A second attachment part 8′ is arranged at the opposite side of the outer ear 6. The first attachment part 8 and the second attachment part 8′ constitute an attachment arrangement 32.

The first attachment part 8 is provided with two attraction members 12, 12′ arranged and configured to be attracted by opposing attraction members 10, 10′ provided in the second attachment part 8′.

The first attachment part 8 is furthermore provided with sensor elements 34, 34′ arranged and configured to interact with corresponding sensor elements 14, 14′. The sensor elements 14, 14′, 34, 34′ may be formed as transmitter units and receiving units, respectively. Hereby, the sensor elements 14, 14′, 34, 34′ can be used to transmit light and detect the received fraction of the light.

It should be noted that in view of any of the embodiment described herein it may be that:

- The sensor element could form an integrated part of the attraction members.
- On or more of the sensor elements are active actuators, e.g. LEDs for shining light through the ear, or for sourcing light to be reflected (perhaps internally) from the ear. Actuators can also be electrodes to electrically stimulate the nerves in the ear.
- On or more of the sensor elements pick up light from the skin or transmitted in the ear.

As used, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well (i.e. to have the meaning “at least one”), unless expressly stated otherwise. It will be further understood that the terms “includes,” “comprises,” “including,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. It will also be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element but an intervening elements may also be present, unless expressly stated otherwise. Furthermore, “connected” or “coupled” as used herein may include wirelessly connected or coupled. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. The steps of any disclosed method is not limited to the exact order stated herein, unless expressly stated otherwise.

It should be appreciated that reference throughout this specification to “one embodiment” or “an embodiment” or “an aspect” or features included as “may” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosure. Furthermore, the particular features, structures or characteristics may be combined as suitable in one or more embodiments of the disclosure. The previous description is provided to enable any person skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other aspects.

The claims are not intended to be limited to the aspects shown herein, but is to be accorded the full scope consistent with the language of the claims, wherein reference to an element in the singular is not intended to mean “one and only one” unless specifically so stated, but rather “one or more.” Unless specifically stated otherwise, the term “some” refers to one or more.

Accordingly, the scope should be judged in terms of the claims that follow.
