Abstract:
A headphone with a headband is provided where the headband is adapted to ensure contact between an earpad and the head or ear of the user, and with a. a speaker unit b. an outer frame comprising a proximal perimeter with two first pivotal hinge points at diametrically opposed positions with respect to the speaker, c. a middle frame, having a proximal and a distal perimeter, hinged for pivotal movement with respect to the outer frame about a first axis defined by a line through the two first hinge points, and where the middle frame comprises second pivotal hinge points at diametrically opposed positions with respect to the speaker, and d. an inner frame having a proximal and a distal perimeter hinged for pivotal movement with respect to the middle frame, about a second axis defined by a line through the two second hinge points, whereby this axis is perpendicular to the first axis, and the speaker and the earpad is attached to the inner frame.
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 λ c 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. The invention may e.g. be used in portable communication devices with a wireless interface for communication with another device, in particular in a headset or a headphone or an active earplug.

Abstract:
The invention relates to an output reducing system for a telephone system, e.g. implemented in a headset, comprising an input line and an output line, where the input line is transmitting an incoming signal to an output transducer and where the output line in transmitting an outgoing signal from an input transducer, where in connection with the input line a compressor system is provided for reducing the output signal level.
