Abstract: A communication device comprising a housing with a housing wall encapsulating a housing interior. A microphone is arranged in the housing interior and communicates via an audio passage with the outside of the housing. An electrical socket is adapted to receive an electrical plug through a socket opening, which is accessible from the outside of the housing. The audio passage comprises the socket opening.

Abstract: A communication device comprises a housing with a housing wall encapsulating a housing interior. A microphone is arranged in the housing interior and communicates via an audio passage with the outside of the housing. An electrical socket is adapted to receive an electrical plug through a socket opening, which is accessible from the outside of the housing. The audio passage comprises the socket opening and the electrical socket includes a socket casing which surrounds the socket opening and extends in the insertion direction of the electrical plug. The socket casing includes through-going holes which form a part of the audio passage. The electrical plug is adapted to be removably inserted in the electrical socket and is provided with latching protrusions, which are adapted to be received in the through-going holes in the socket casing, when the electrical plug is inserted in the electrical socket.

Abstract: A communication device (1) comprising a housing (2) with a housing wall (3) encapsulating a housing interior (4). A microphone (5) is arranged in the housing interior (4) and communicates via an audio passage (9) with the outside of the housing (2). An electrical socket (6) is adapted to receive an electrical plug (7) through a socket opening (8), which is accessible from the outside of the housing (2). The audio passage (9) comprises the socket opening (8).

Abstract: Bulk yarns having improved elasticity and recovery and methods for their manufacture are described. A first embodiment of the invention involves providing a solution-dyed multifilament yarn of polybutylene terephthalate (PBT) and a multifilament yarn of a second thermoplastic polymer to an air jet texturizer such that the PBT component forms a core and the other yarn forms a plurality of loops and coils extending outwardly from the core. In addition to a high degree of elasticity and recovery, the composite yarn also has a low amount of shrinkage, which enables the yarns to be used in the production of woven fabrics without significant losses in fabric yield. Another embodiment of the invention involves false twisting a multifilament PBT yarn and a second multifilament yarn as individual threadlines to impart crimp thereto, then entangling the two components together using an air interlacing jet, to produce a bulk yarn having high elasticity and recovery.
