20080025539
This application claims priority of German application No. 2006 030 600.7 filed Jul. 3, 2006, which is incorporated by reference herein in its entirety.
The invention relates to an otological device, for example, a hearing aid or a tinnitus masker, to be worn in the area of a listener's ear.
DE 332 810 0 A1 discloses a miniature sound transmission device, which comprises a holding device for wearing on a pinna. The holding device for wearing on a pinna can be tucked into an auditory canal.
DE 297 184 83 U1 discloses a holding device for the attachment of otological devices. The holding device is designed to be connected to an otological device. The holding device has interconnected support elements which are each provided for securing the holding device with a positive fit on the inside of a concha.
With in-the-ear hearing aids known from the prior art, there is the problem that the hearing aid is difficult for a user to access or can be difficult to remove. A further problem is that an in-the-ear hearing aid completely closes the auditory canal, something that is associated with a corresponding sensation for a wearer when worn and with a corresponding optical impression for other people.
With behind-the-ear hearing aids, there is the problem that it is only with difficulty or with very considerable discomfort that such hearing aids can be worn in conjunction with a visual aid.
The problem is solved by an otological device, for example, a hearing aid or a tinnitus masker, to be worn in the area of a listener's ear, the otological device being designed to be worn at least partially attached to the tragus of a listener's ear.
Such an otological device can advantageously be designed so that it does not completely close an auditory canal. A further advantage is that such an otological device can be worn on the tragus of a listener's ear and thus does not have a clip to attach it behind a listener's ear so that a visual aid and a hearing aid can be worn together.
In a preferred embodiment, the otological device has a holding device, which is designed to encompass at least partially a tragus of a listener's ear. Preferably, the otological device can be attached to a tragus, in particular with a positive or non-positive fit. As a result, the otological device can be worn on a tragus in such a way that it cannot be dislodged from the tragus by accelerations caused in particular by the movements of a wearer.
For example, the holding device can at least partially enclose a tragus—in particular between two gripping elements formed by the holding device or by a clip that is thus formed and thus lock onto the tragus.
In an advantageous embodiment, the holding device is at least partially formed by a retaining clip that is functionally connected to the otological device, the retaining clip being designed to at least partially enclose a tragus of a listener's ear.
Advantageously, the retaining clip can be connected to the otological device by means of a spring element. The spring element can advantageously have a lower modulus of elasticity than the retaining clip itself. As a result thereof, a contact pressure of the retaining clip on a tragus can advantageously be predetermined by means of a modulus of elasticity of the spring element.
In an advantageous embodiment, the retaining clip is integrally connected to at least one housing component of the otological device.
In this way, during a production process a retaining clip can be molded onto an otological device in a simple manner, and for example, manufactured in an injection molding step of an injection molding process.
In a preferred embodiment of the holding device, said holding device has holding tongs which are partially formed by a retaining clip of the aforementioned type and partially by a housing component of the otological device. In this way, holding tongs can advantageously be formed, one holding tong claw being formed by the retaining clip and one holding tong claw provided to apply counter-pressure being formed by at least one part of the hearing device housing.
In an advantageous variant of the otological device, the retaining clip is connected to the otological device by means of a joint, in particular a pivotable joint or a ball joint.
For example, in the case of an embodiment having a pivotable joint, the retaining clip can be functionally connected to a push spring which is arranged and designed to push the retaining clip onto a tragus, preferably onto the side of the tragus that faces the auditory canal. A hearing device housing or a part of a hearing device housing, for example, can form a counter-bearing for the push pressure that is thus exerted.
In the case of a ball joint, the otological device can, for example, have a locking device, in particular having a bayonet pin, which is designed to provide spring-actuated locking of a ball of a ball joint.
In addition to the ball joint, in a variant of an otological device having a ball joint, a retaining clip can be connected to a housing of the otological device by means of the ball joint and in particular also have a push spring to push the retaining clip against a tragus.
In an advantageous embodiment, the holding device is at least partially spring-mounted such that a sufficient push pressure on the tragus can be generated to secure the otological device on a tragus.
In this embodiment, the retaining clip itself can, for example, have a modulus of elasticity and/or, in an area of the retaining clip in which the retaining clip is molded onto a hearing device housing, a geometrical shape which gives the retaining clip an increased mobility in this area, in particular the ability to pivot.
In a preferred embodiment, in an arrangement provided for wearing on a listener's ear, the otological device is at least partially arranged outside the concha without gripping behind the pinna. In this way an otological device can be perceived by another person as being turned outwards.
In an advantageous embodiment of the otological device, the otological device has a mechanical interface for connection to a decorative plate, the decorative plate being designed to at least partially conceal the otological device, such that the otological device cannot easily be seen or cannot be seen at all by a third party when the otological device is worn on a listener's ear. In this embodiment the impression given to another person is rather that of a piece of jewelry.
In a preferred, advantageous embodiment of the otological device, in an arrangement to be worn on a listener's ear, the otological device is designed to fill only partially the auditory canal and/or the concha. As a result, advantageously, it is at least partially possible for other people to see into an auditory canal of a wearer of the otological device and in this way a natural appearance can be conveyed. In this embodiment, the otological device is perceived, for example, as a piece of jewelry or as an unobtrusive auxiliary device.
An otological device can advantageously have a mechanical interface for connection to a covering element. Such a covering element can, for example, convey the impression of a piece of jewelry or can advantageously form a piece of jewelry itself.
Advantageously, such an interface can be formed on one side of the otological device by an indentation or an opening or a recess in a hearing device housing, which is designed for the insertion of or connection to a corresponding counterpart in a covering device.
A covering device for an otological device of the aforementioned type can advantageously comprise a tappet or a peg or a pin which is designed for insertion into a corresponding recess in an otological device. Naturally the otological device or a housing of the otological device can have a tappet, a peg or a pin or suchlike which is, in each case, designed to engage with a corresponding recess of a covering device with a non-positive and/or positive fit.
In this embodiment, a covering device can advantageously have a corresponding recess, indentation or an opening, into which a tappet or a peg or a pin of an otological device can engage.
An otological device which is designed as a hearing aid can have a sound receiver and a sound generator.
The sound receiver is designed to receive sound waves and to generate a microphone signal representing the sound waves received.
The sound generator is designed to generate a sound as a function of a power signal received at the input end.
The hearing aid preferably has a transmission unit, which is connected at the input end to the sound receiver and at the output end to the sound transmitter and in which the transmission unit is designed to generate a power signal as a function of a microphone signal received at the input end, which power signal at least partially represents the microphone signal.
Advantageous materials for a hearing aid housing are biocompatible and can in each case comprise polypropylene, polyethylene, polyester, polyamide, polystyrene or polycarbonate or a combination thereof.
An advantageous embodiment of the otological device can comprise (in particular in addition to a holding device for locking onto a tragus) a support device which is designed to support the hearing aid additionally on at least one edge section of the concha and/or on a wall area of the concha with a positive and/or non-positive fit.
Such a support device can advantageously be designed as a ring support which is formed by an open ring having a first and a second open end.
The first open end of the ring support is preferably connected to the holding device, in particular to a retaining clip, in particular in a separable-manner. The second open end of the ring support is preferably connected to a section of the housing of the otological device, in particular in a separable manner.
The ring support is preferably designed to be elastic. For example, the ring support can be formed using a thermoplastic.
Further advantageous design variants of an otological device result from the features set out in the dependent claims or from a combination of the features set out in the dependent claims.
The invention is now described below with reference to the figures and further exemplary embodiments of an otological device.
