Abstract: The invention concerns a communication device for placement at the ear of a user. A battery and transmission part is shaped to rest behind and above the ear lobe of a user and a speaker and microphone part is arranged to extend downwards in front of the ear canal. The two parts are interlinked to pivot, at least in the sagittal plane, with respect to each other and the battery and transmission part accommodates a battery as well as signal processing and transmission electronics, and the speaker and microphone part accommodates a speaker element and a microphone boom arm and further, the two parts have mating surfaces such that a pivotal motion between the two, when the device is not at the ear, will bring a surface of the first part and a surface of the second part together. Further the link between the two parts comprises a hollow ball joint connection allowing leads to pass through the ball joint. Also a magnet is inserted in the one part and a sensor for sensing the magnetic field from the magnet is comprised in the other part, such that the movement between the two parts may be registered and used to control the function of the device or for giving audible indication signals to the user.

Abstract: The invention relates to a communication device comprising a wireless interface for enabling wireless transmission and/or reception at a predefined wavelength λc to be established. The object of the present invention is to provide an antenna suitable for wireless communication in a portable communication device. The problem is solved in that the communication device comprises a housing having an electrically conductive part, the wireless interface comprising an antenna comprising a first quarter wavelength patch and a ground plane comprising an electrically conductive material, the first quarter wavelength patch being at least partially constituted by said electrically conductive part of the housing. This has the advantage of providing an alternative wireless interface for a communication device.
