Abstract: There is provided a dynamic sound transducer having a diaphragm system (10) which has at least a first and second metallized surface (11) which are separated from each other by an insulating surface (12). The dynamic sound transducer further has a moving coil (20) with a coil wire (25). An end of the coil wire is electrically conductingly connected to the first metallized surface (11) and the other end of the coil wire is electrically conductingly connected to the second metallized surface (11).

Abstract: There is provided an auditory canal earphone comprising a housing (120) for receiving an electroacoustic transducer and a sound guide unit (130) on the housing (120) for feeding audio signals produced by the sound transducer into an auditory canal of a user of the auditory canal earphone. The sound guide unit (130) has an outside (136). The auditory canal further has at least one ear adaptor (200) with an inside wall (220) for at least partial placement over the sound guide unit (130) and an outside wall (210) for sealing off the auditory canal. The auditory canal earphone further has a tube (400) between the outside (136) of the sound guide unit (130) and the inside wall (220) of the ear adaptor (200).

Abstract: There is provided an earphone having at least one housing (10) and at least one electroacoustic transducer (20) having a first and a second surface (21, 22). The earphone further has a first volume (100) defined by the first surface (21) of the electroacoustic transducer (20) and by a first end (12) of the housing (10), and a second volume (200) defined by the second surface (22) of the electroacoustic transducer (20) and by a second end (11) of the housing (10). An opening (300) is provided between the first and second volumes (100, 200). A closing unit (30) serves to at least partially close the opening (300).

Abstract: There is provided a dynamic sound transducer having a diaphragm with a ridge. First and second grooves (20, 30) are arranged on a first side of the ridge in such a way that the first and second grooves cross each other.

Abstract: A phone, particularly an ear phone, is provided that features two transducer housings (41, 42) and a flexible head strap (43). The head strap (43) is pre-shaped in such a way that it is coiled up and has at least one turn in its relaxed and unworn state. In this way, the phone can be stowed in a space-saving fashion when it is not worn.

Abstract: There is provided an earphone having an ear hook, at one end of which is arranged a first end of a sliding shaft and at the other end of which (at the ear lobe abutment end) the cable is fixed. The housing of the electroacoustic transducer is connected to the second end of the shaft in such a way that the housing of the electroacoustic transducer can be moved in the longitudinal direction of the shaft.

Abstract: Method and devices for providing surround audio signals are provided. Surround audio signals are received and are binaurally filtered by at least one filter unit. In some embodiments, the input surround audio signals are also processed by at least one equalizing unit. In those embodiments, the binau-rally filtered signals and the equalized signals are combined to form output signals.
