This application claims priority to European patent application No. 17157633.3, titled “A Hearing Device with an Optical Identification,” filed on Feb. 23, 2017, which is incorporated herein by reference for its entirety.
The disclosed technology relates to a hearing system with a left and a right hearing device with an optical or visual identification to distinguish or identify the hearing devices.
Users want to easily identify hearing devices. For example, a user wants to be able to easily distinguish a left hearing device from a right hearing device or one hearing device model from another model. A method and system for identifying or distinguishing hearing devices is disclosed in EP 1890522. The patent discloses a colored plate, e.g., blue for the left hearing device and red for the right hearing device. Such color identifications have the disadvantages such as providing limited information (e.g., left or right) or being unhelpful for colorblind individuals. Accordingly, there exists a need to address these shortcomings and improve it.
In some implementations, the disclosed technology solves a problem of identifying a hearing device or distinguishing a hearing device from another hearing device. The disclosed technology can include an optical identification (also referred to as a “visual” identification) that is versatile and that enables the identification of device-specific information, such as serial number, type and class, or a left or right coding.
In some implementations, the disclosed technology includes a hearing system that comprises a left and a right hearing device each with a housing and an optical identification, wherein the optical identification comprises a first shield and a second shield that are arranged on the housing, wherein the second shield forms a part of the outer surface of the hearing device, wherein the second shield is arranged over the first shield and wherein the second shield is at least partially transparent. In some implementations, the shield is referred to as a “panel”, where panel is a flat or curved component that forms or is set into a surface of the hearing device (e.g., exterior or interior surface of a hearing device).
In some implementations, the disclosed technology has the advantage that various information about the hearing device can be allocated or located in one area of the hearing device. Additionally, the first and second shield can be used in any combination on a variety of hearing devices. The transparency of the second shield enables the visibility of information on the first shield through the second shield, at least partially. In some implementations, the hearing system comprises two hearing devices, where one hearing device is the “first hearing device” and the hearing device is the “second hearing device”. Although a first hearing device can be the left hearing device and second hearing device can be the right hearing device, it is also possible that the hearing devices are generic (e.g., not programmed for left or right).
At least partially transparent generally means that the entire second shield is made from a material that is transparent or semi-transparent. Alternatively, the second shield can comprise regions, like windows, that are transparent or semi-transparent. This enables a great number of variations and provides a great flexibility in application.
In an embodiment, the first shield comprises a first identification feature and the second shield comprises a second identification feature. Having different identification features on the first and second shield facilitates the recognition of each feature. In another embodiment, the first and second identification feature is at least one of sign or color. Signs and color can be easily detected and recognized by the human eye. A sign can comprise one or more signs and can comprise one or more type of signs. Signs can be selected from the group of letter, number and shape, alone or in combination.
In a further embodiment, the first identification feature is a sign and the second identification feature is a color. This enables the clear distinction between identification features on the first shield and those on the second shield. For example, technical information of the hearing device, such as serial number, type or class, can be allocated on the first shield and usage information, such as usage for the left or the right ear, can be allocated on the second shield. With this setup, the first shield can be used for any hearing device with the same technical specification and the second shield can be used for any hearing device that is to be placed in the same ear.
In some embodiments, the housing comprises a recess for receiving the second shield. This enables a substantially flush arrangement of the second shield with respect to the housing. Such a design is optically appealing and avoids protruding parts that are not comfortable for the user and are prone to things getting stuck on them.
In another embodiment, at least one outer rim of the recess forms a first retention for the second shield. With this, the second shield can easily be arranged and cantered within the recess. With one first retention, the second shield can be slipped in the recess from the side opposite the first retention. With two or more first retentions, the second shield needs to be flexible, meaning reversible deformable, so that it can be bent and squeezed in the recess to engage in a form fit with the corresponding part of the housing. With such a design, no additional fixation means is necessary.
In a further embodiment, the second shield comprises a disk-shaped body, wherein at least one inner rim of the body forms a first nose that is adapted to engage the corresponding first retention of the housing. The number of noses corresponds with the number of retentions in the housing. Alternatively, there can be less noses than retentions. The shape of each nose corresponds to the shape of each respective retention.
According to another embodiment, the second shield comprises a second nose that extends from the surface defined by the inner rim of the body and wherein the device further comprises a second retention for the second shield. The second retention abuts the housing from the inside at least in a central area of the recess. The second retention extends towards the second shield over the first shield and is adapted to engage the second nose of the second shield. The combination of the first retention with the first nose and the second retention with the second nose form a snap closure. Such a design does not require an additional fixation means, such as a screw that is difficult to tighten and can easily be lost.
In an embodiment, the part of the second retention that extends over the first shield is a notch. A notch can easily be manufactured and its design enables an accurate setting of a desired retention force. According to an embodiment, the second retention is an elongate element that is arranged in a central region of the recess of the housing and extends through a corresponding cut in the first shield. With this, the first shield is centered by the second retention.
In a further embodiment, the second retention extends through an inner surface of the recess and the area of the inner surface around the second retention is made of a sealing element. This prevents liquids and particles from entering the inner part of the housing, where electronics is located.
In yet another embodiment, the second retention is a flat element that extends over more than the entire width of the recess of the housing and extends sideways around the first shield. With this, the first shield is well positioned and no additional retention element is needed.
Per an embodiment, the second retention forms an inner surface of the recess and a sealing element is arranged around the second retention in the region where the second retention abuts the housing. The sealing element is for example an 0-ring or the like.
In a further embodiment, the hearing device comprises a relief on the side of the body of the second shield opposite to the first nose that is formed by the second shield and the housing, wherein the relief is adapted to allow the engagement with a tool for removing the second shield. The relief can be defined mainly by the second shield or can be defined mainly by the housing. The relief can be defined on at least three sides by the second shield and on at least one side by the housing or the relief can be defined on at least three sides by the housing and on at least one side by the second shield.
A hearing system can comprise a left and a right hearing device according to one of the above-mentioned embodiments.
According to another embodiment, the hearing device comprises a clearance that is adapted to form a snap connection with a corresponding loading station. The clearance can be formed in the housing or in the second shield. The allocation of the clearance in the second shield enables an easy adaption of the hearing device to a loading station by simply changing the second shield. In a further embodiment, the second shield is a circular disk, that can be inserted in a circular recess in the 25 housing. The recess in the housing comprising reliefs for receiving latches arranged on the circumference of the second shield. The second shield comprising a recess in which a tool, such as a screw driver, a coin or the like can be inserted for loosening the second shield within the recess of the housing by means of a rotary movement. The second shield and the housing forming a Bayonet closure.
The first shield can be arranged in a relief in the recess of the housing or can be arranged in a relief in the second shield. A sealing element can be arranged in a peripheral area of the second shield. The features of the above-mentioned embodiments of the hearing device can be used in any combination, unless they contradict each other.
