Control panel with activation zone

An interchangeable hearing aid control panel with at least one activation zone arranged in connection with a layered structure. The layered structure has an electrically non-conducting substrate, an electrically conducting path arranged in connection with the substrate, and an electrically conducting member, such as a conducting foil, arranged at a predetermined distance from the activation zone. The activation zone can be either in a deactuated or in an actuated state. In the actuated state the conducting member and the conducting path are electrically connected while disconnected in the deactuated state. Electrical connection to an associated hearing aid is by means of a connector, such as a plug, enabling the control panel to be easily changed. Preferably, the connector is formed by a piece of flexprint. The layered structure may comprise a second conducting path. In preferred embodiments activation zones are indicated by “poppel domes” formed by a surface layer covering the layered structure. The activation zones may form an MTO control or a volume control. To fit BTE hearing aids, the layered structure preferably has an elongated structure with a length of 1-4 cm. Other shapes can be formed to fit ITE, ITC and CIC hearing aids. In preferred embodiments, the control panel comprises one or more Silicon-based microphones protected behind a surface layer of the control panel.

Lifting support device for key, key and keyboard

The invention relates to a lifting support device for a key, the key and a keyboard. The lifting support device comprises a first connection rod and a second connection rod. The first connection rod is provided with a first arm portion and a second arm portion, the first arm portion is provided with a first opening groove, and the second arm portion is provided with a first protrusion portion. The second connection rod is provided with a third arm portion and a fourth arm portion, the third arm portion is provided with a second protrusion portion, and the fourth arm portion is provided with a second opening groove. The second protrusion portion extends along a first direction and abuts against the first opening groove, and the first protrusion portion extends along a second direction and abuts against the second opening groove, so that the first connection rod is connected with the second connection rod and the first direction is opposite to the second direction. When the second protrusion portion abuts against the first opening groove and the first protrusion portion abuts against the second opening groove, the first connection rod and the second connection rod can pivot along a virtual axis, and the first direction and the second direction are vertical to the virtual axis respectively. By means of the design, the structure is simple, the assembly is convenient, machining and assembly complexities are reduced, and the material manufacture cost is decreased.
