Method and device for identifying the position of loudspeaker boxes in a loudspeaker box arrangement
Patent number: 9872118Abstract: A method for identifying the position of loudspeaker boxes in a loudspeaker box arrangement includes the operation of a first loudspeaker box in the loudspeaker box arrangement as an acoustic test signal generator. An acoustic test signal from the first loudspeaker box is received at other loudspeaker boxes in the loudspeaker box arrangement. A positional relationship between the signal-generating first loudspeaker box and at least one of the other loudspeaker boxes in the loudspeaker box arrangement is ascertained on the basis of the acoustic test signal received in the other loudspeaker boxes.Type: GrantFiled: April 20, 2016Date of Patent: January 16, 2018Assignee: D&B AUDIOTECHNIK GMBHInventors: Frank Bothe, Matthias Christner, Fabian Braun -
Patent number: 9288571Abstract: A loudspeaker system has a loudspeaker housing that comprises at least a first and a second housing chamber. The loudspeaker system has a bass loudspeaker that is mounted on a partition between the first housing chamber and the second housing chamber, wherein the back of the bass loudspeaker has the first housing chamber present and the front of the bass loudspeaker has the second housing chamber present. The partition contains at least one bass reflex opening. A phase correction element is arranged at the front of the bass loudspeaker in the second housing chamber. The bass reflex opening opens into the second housing chamber and is arranged in a region adjacent to the phase correction element.Type: GrantFiled: September 24, 2014Date of Patent: March 15, 2016Assignee: d&b audiotechnik GmbHInventors: Matthias Christner, Nico Paul

Patent number: 9071212Abstract: An audio amplifier may comprise a signal limiting circuit and a power amplifier. The signal limiting circuit may be configured to limit an audio signal received at an input and to provide it as a limited audio signal at an output. The power amplifier may have a supply connection which may be coupled to a power supply unit in order to supply power to the power amplifier. The power amplifier may be configured to amplify a signal, which may be based on the limited audio signal, and to provide it as a level-limited audio signal at an output which may be coupled to a load, so that the load may be operated at limited power. The signal limiting circuit may be configured to produce an audio signal which may be limited depending on the load.Type: GrantFiled: September 27, 2012Date of Patent: June 30, 2015Assignee: d&b audiotechnik GmbHInventors: Sven Moertel, Claus Renftle, Hermann Vogt
