This application claims priority of German application No. 10 2005 037 897.8 filed Aug. 10, 2005, which is incorporated by reference herein in its entirety.
The present invention relates to a hearing device, especially a hearing aid, with a program switch to switch into a number of hearing programs, and a programming socket for connecting the hearing device to a programming device.
Numerous hearing devices are provided with the facility for selecting different hearing programs. To this end they have a pushbutton switch which allows the individual programs to be selected at the push of a button.
In addition modern hearing aids generally posses a programming interface via which individual programming is possible. The programming interface is mostly realized as a programming socket or a programming contact.
The pushbutton switch for program selection usually needs a separate control since it is generally very small. A plastic button which presses on a membrane switch is frequently used for this purpose. The button simultaneously represents a cover and a protection for the membrane switch.
A further cover is provided as a rule for the programming socket. This serves to keep the electrical contacts of the programming circuit free from contamination.
A behind-the-ear hearing device is known in this context from DE 296 02 921 U1 which features a covering device for the programming socket and a pushbutton. The covering device is embodied a hinged flap and additionally features a mounting with a cutout for a control.
In addition a programmable hearing aid is known from publication DE 88 00 629 U1 or publication EP 0 591 791 B1 in which the programming socket can be covered by a simple flap
The object of the present invention is to simplify the design of a hearing device or a hearing aid.
In accordance with the invention this object is achieved by a hearing device, especially a hearing aid, with a program switch to switch into a number of hearing programs and a programming socket for connecting the hearing device to a programming device, as well as a cover unit which is embodied in one piece and covers both the program switch and the programming socket, with the covering device having a locking element, with which it is retained in the closed state over the program switch and the programming socket so that it can be removed, and with the cover unit able to be moved slightly in the closed state so that the program switch can be actuated by its movement.
Advantageously the inventive solution saves on one plastic part, since the cover unit has multiple functionality. On the one hand it covers both the programming switch and also the programming socket and on the other hand it is also used for actuation of the program switch. Consequently one fewer injection molding tool needs to be manufactured for hearing aid production, and in manufacturing as well as in service one fewer part needs to be handled.
Preferably the cover unit is supported on a hinge on the housing of the hearing device. This type of support is simple to implement and to install.
In accordance with a further development the cover unit on the distal i.e. free end in relation to the pivot axis features a touch section, and the program switch lies in the closed state between the pivot axis and the touch section, so that a pressure on the touch section magnifies a pressure on the program switch through a lever action. In this way the operating convenience of the hearing device can be increased.
In accordance with an alternate embodiment the cover unit can be supported to enable it to slide on the housing of the hearing device, so that the program switch can be actuated by a sliding movement of the cover unit. Such a slider would possible have the advantage over a flap of reducing the danger of loss or damage to it when the programming socket is uncovered.
The locking element is usefully a snap-in element. This allows a releasable lock to be implemented in a very simple manner.
Furthermore the programming switch can be implemented by a membrane switch. Such a membrane switch represents a low-cost standard component.
The invention will now be explained in more detail on the basis of the enclosed drawings, which show:
The exemplary embodiments described in greater detail below represent preferred embodiments of the present invention.
The behind-the-ear hearing aid shown in
An enlarged view of the cover unit 2 is shown in
Below the cover unit 2 a membrane switch 4 can be seen which serves as a program switch. It is connected via a cable 5 to a signal processing unit or the hearing device not shown in the drawing.
Below the control 2 there is also a programming socket 6, with which the hearing aid can be individually programmed.
The cover unit 2 is embodied in one piece, as an injection-molded part in this case. It features a hinged support section 3, and at its free end a raised control section 7 with ridges 8 to make it easier to grip. There is space below the raised control section 7 which is embodied as a bell shape, for the programming socket 6 in the closed state shown in
At the outermost free end of the cover unit 2, i.e. at the tip of the control section, there is a molded-on hook 10. In the closed state of the cover unit shown in
The cover unit 2 can be opened by least 90 degrees around the hinged support 3. This results in the position illustrated in
In the opened state shown in
The cover unit 2 thus has the following functionalities:
Covering the program switch,
Covering the programming socket,
Control for the program switch and
Transferring the actuation force for the program switch.
