A filter for a microphone system of a miniature electronic device. The filter includes a sound inlet and a sound outlet, wherein the filter is adapted to be mounted on a surface of a printed circuit board.

Filter for a microphone system, a microphone system, a miniature electronic device and a method of equipping a printed circuit board

A hearing device comprising a locking mechanism for connecting an external component to the hearing device, the locking mechanism comprising a part () arranged at or in the housing wall () of the hearing device, moveable from or out of the housing wall such that by moving the part back towards the housing wall a section of the part is fixing a connecting element of the external component to the hearing device or housing of the hearing device respectively.

Hearing device comprising a locking mechanism for an external connector and method thereof

A hearing device with a connecting portion () for the connection of a hook or acoustic tube comprises an inside thread () or internal thread portion at the connecting portion intended for the attachment of a hook or acoustic tube.

Attachment of a hook to a hearing device

For the connection of a programming device to a hearing device an insertable plate () into the casing or frame of the hearing device is provided, comprising on one side contacts () to the hearing device electronics and on the other side contact pins (), provided for the connection of a contact adapter/cable system of the programming device.

Integral connector for programming a hearing device

In a hearing device with an audio signal processing stage () and an Rf signal processing stage () the Rf signal processing stage is realized in one module (), whereas the audio signal processing stage is realized in a second module (). The two modules are releasably interlinked by means of a releasable positive locking link ().

The inventive control element is provided with a mechanical actuator () and an electrical or electromechanical switching element (), whereby the switching element () comprising of at least one push button () reacting upon pressure. Thereby, the actuator () is arranged elastically or resiliently relocatable or tiltable with respect to the switching element () or the push button () respectively and an actuating cam () is further provided at the actuator () facing the push button (), whereby the actuator () and the switching element () are not directly connected to each other. The dividing of the control element into two parts, one mechanical actuating part () and one electrical switching part (), permits the replacement or exchange only of the mechanical actuating () part without any influence to the electrical switching part (). The replacement or exchange therefore may take place without the need of desoldering of the electrical switching part () from its printed circuit board or from its connected wires.

Control element with a mechanical actuator

The switching element ( ) of the switch per this invention is closely enveloped, at least in the area of its free end, by an elastic diaphragm ( ) which also encloses, at a distance, the contact surfaces ( ) facing the switching element ( ) and which is tightly connected to the switch housing ( ). This tightly seals the contact region against the external environment of the switch and thus reliably prevents contamination and oxidation of the contact surfaces. As another advantageous feature, the number of switch components is thus reduced, a mechanical spring is not needed for retaining the switching element ( ) in its engaged position, and the design permits miniaturization.
