Abstract: The present invention relates to a receiver module being adapted to be positioned in an ear canal, the receiver module comprising a receiver having a receiver housing, said receiver being adapted to receive a time dependent electrical signal, said receiver further being adapted to generate outgoing acoustic waves via an output port in the receiver housing in response to the received time dependent electrical signal, and expansible means surrounding at least part of the receiver housing, said expansible means having an opening aligned with the output port of the receiver housing so as to allow the generated outgoing acoustic waves to penetrate away from the receiver module and into the ear canal.

Abstract: A microphone assembly for mounting in an electronic communication device, and wherein the microphone assembly comprises one or more sound inlet port(s) with channels (7), and one or more microphone(s) inside a housing (1). One or more controlling means (5) are an integrated part of the microphone assembly, said controlling means comprising a sound inlet part (6) composing a button and being surrounded by a second casing part (8), the button being loaded by a spring (9). The housing (1) comprises a terminal (2) for grounding the microphone, a terminal (3) connected to e.g. a battery, and a terminal (4) for signalling out.

Abstract: A waterproof contact comprising a base plate, a side-wall extending from the base plate in a substantially vertical direction so as to form a housing, said housing having an opening essentially opposite to the base plate. A first and a second outer terminal penetrate the base plate so as to form a first and a second contact area on an inner surface of the base plate. A movable knob is adapted to be moved in a direction substantially perpendicular to a plane defined by the inner surface of the base plate, said knob comprising a bottom part positioned in the housing, a top part positioned outside the housing, and a middle part connecting said bottom and top part and being positioned in the opening of the housing. An electrical conductor is attached to said bottom part for providing electrical contact between said terminals, and the contact comprises sealing means for providing a waterproof seal between said housing and said movable knob.

Abstract: A battery holder for a microelectronic device, said holder comprising a frame having a substantially circular base and a curved portion with an upper and a lower surface. The curved portion encloses at least part of the substantially circular base, and the frame is adapted to hold a battery. A first conductor extends from a first part of the curved portion to a second part of the curved portion, and wherein a first end of the first conductor is positioned within the first part of the curved portion and wherein a second end of the first conductor is positioned within the second part of the curved portion. A movable member is positioned on the curved portion and adapted to provide an electrical connection between the second end of the first conductor and a point of contact within the second part of the curved portion.
