Abstract: An earphone is provided that has two diaphragms that are stretched on a frame and that are driven by means of an electroacoustic sound transducer that is not provided in the region of the two diaphragms. Instead, the sound transducer is acoustically coupled to the two diaphragms via a sound duct. The sound transducer preferably has a front and a rear volume, wherein the front volume of the sound transducer drives the two (parallel) diaphragms via the sound duct. This allows the provision of no electroacoustic reproduction transducer in the central region of the earpiece of an earphone.

Abstract: There is provided a headphone or headset comprising at least one housing, at least one microphone for detecting interference sound, at least one active noise compensation unit for implementing active noise compensation based on the interference sound detected by the at least one microphone and for the output of a compensation signal. The headphone or the headset has at least one electroacoustic reproduction transducer for output of the compensation signal from the noise compensation unit and a circumaural cushion having a recess for receiving a spectacles side arm. The active noise compensation unit is adapted in noise compensation to take account of the effect of the recess in the ear cushion.

Abstract: There is provided a headset having a head band, at least one fork for receiving an earpiece and a receiving portion between an end of the head band and one of the forks. The fork is arranged pivotably about a pivot axis. The fork has a first end having a support element. The receiving portion has a slider having at least two receiving positions. The support element engages into one of the at least two receiving positions of the slider and thus limits the maximum deflection of the fork about the pivot axis.

Abstract: There is provided a headphone or headset comprising at ;east one housing (150), at least one microphone (120, 130) for detecting interference sound, at least one active noise compensation unit (100) for implementing active noise compensation based on the interference sound detected by the at least one microphone (120, 130) and for the output of a compensation signal. The headphone or the headset has at least one electroacoustic reproduction transducer (140) for output of the compensation signal from the noise compensation unit (100) and a circumaural cushion (160) having a recess (161) for receiving a spectacles side arm (210). The active noise compensation unit (100) is adapted in noise compensation to take account of the effect of the recess (161) in the ear cushion.

Abstract: There is provided an entertainment system comprising at least one seat, an electronic unit (100) for active noise reduction in the seat and at least one headphone (300). The headphone has an electro-acoustic reproduction transducer (310), a microphone (330) for recording interference signals and an adjusting unit (320) having an active filter for correcting a frequency response characteristic of the output signal of the microphone, for performing pre-filtration for active noise reduction and for the output of a corrected and filtered signal. The electronic unit (100) performs active noise reduction based on the corrected and filtered signal of the adjusting unit (320).

Abstract: A headset, which can have an electroacoustic reproduction transducer, a unit for performing active noise reduction and a boom microphone. The headset further can have a voltage converter unit for converting a supply voltage received into a supply voltage for the active noise reduction unit.

Abstract: There is provided a wireless communication system in an aircraft. The system has at least one wireless headset (100) having a first wireless transmitter/receiver and a cockpit (200). The cockpit (200) has a second wireless transmitter/receiver (230) for wireless communication with the at least one wireless headset (100).

Abstract: There is provided an earphone comprising a first housing (2) with a first control unit (30), a first electroacoustic reproduction transducer (W1, a first operating element (20) and a first microphone (40) for recording speech signals (SS). The first control unit (30) is electrically connected to the first operating element (20), the first microphone (40) and the first electroacoustic reproduction transducer (W1). The control unit receives an audio signal (AS) to be reproduced and in a first mode of operation the control unit outputs that signal for reproduction to the first electroacoustic reproduction transducer (W1). The earphone further has a second housing (3) with a second control unit (50) and a second electroacoustic reproduction transducer (W2). The second control unit (50) receives an audio signal (AS) to be reproduced and outputs that audio signal to the second electroacoustic reproduction transducer (W2).

Abstract: The invention relates to a device consisting of a storage device for storing electrical energy. This may, for example, be a battery, an accumulator or another electrical storage device, for example a capacitor (double-layer capacitor). In the present application, the object is now pursued of keeping the consumption of electrical energy as low as possible, to economize relative to previous solutions and to bring about a great simplification from the point of view of manufacturing.
