Definitions

  • the invention relates to a device for reproducing audio signals.
  • the invention also relates to a method for reproducing audio signals.
  • the invention also relates to a vehicle, a building and a mobile terminal.
  • the DE 10 2005 052 904 A1 describes a system for reproducing audio signals with means for generating virtual sound sources by means of loudspeakers arranged horizontally next to one another.
  • a loudspeaker panel is assigned to each playback channel and consists of two horizontally and closely spaced loudspeakers.
  • a 3 dB filtering takes place in a filter module in each playback channel.
  • a system assembly is assigned to each loudspeaker panel.
  • the system board contains an input module, a switching module, a filter module and an amplifier module.
  • WFS wave field synthesis
  • an audio signal is fed into the input module at the input.
  • the switching module is switched to non-WFS mode, the audio signal reaches the filter module.
  • the audio signal processed in this way is fed to each loudspeaker of the loudspeaker panel via the amplifier module.
  • the invention is based on the object of specifying a device for reproducing audio signals which is improved over the prior art, an improved method for reproducing audio signals and a vehicle, a building and a mobile terminal.
  • the object is achieved according to the invention by a device which has the features specified in claim 1, by a method which has the features specified in claim 6, by a vehicle which has the features specified in claim 7, through a building which has the has features specified in claim 8, and by a mobile terminal which has the features specified in claim 9.
  • the device for reproducing audio signals comprises a plurality of reproduction units which are designed for separate output of audio signals and each comprise at least two loudspeakers for at least stereophonic output of the audio signals.
  • the device further comprises a control unit for controlling the playback units, the controller comprising a coordination of the separate outputs of the audio signals carried out by means of the playback units.
  • the device enables a separate, at least stereophonic output of audio signals, so that, for example, audio signals output from different sources in a musical work can be output separately, but in a time-coordinated manner with one another. This significantly improves the sound quality and, due to a demarcation between the audio signals from the different sources, the intelligibility of musical works.
  • control unit is designed to control several playback units in such a way that singing of a musical work and a tone sequence of the same musical work generated by means of at least one musical instrument can be outputted synchronously by separate playback units. This promotes both the improved intelligibility of text components of a musical work and the improved perception of musical instruments.
  • control unit is designed to control multiple playback units in such a way that tone sequences of a musical work generated by multiple musical instruments can be outputted synchronously by separate playback units for each musical instrument and / or for multiple groups of musical instruments.
  • tone sequences of a musical work generated by multiple musical instruments can be outputted synchronously by separate playback units for each musical instrument and / or for multiple groups of musical instruments.
  • a group of musical instruments for example string instruments or wind instruments, or musical instruments with at least essentially the same timbre can be reproduced separately, whereby the sound quality increases.
  • the separate playback for each musical instrument of a musical work produces a further improved sound quality.
  • the audio signals include at least one playback unit singing a musical work. With such a separate output of vocals, the intelligibility of text components of a musical work can be significantly improved.
  • the audio signals of at least one playback unit comprise a sequence of tones of a musical work generated by means of at least one musical instrument.
  • control unit is designed to convert a musical work into audio signals that include singing of the musical work, and audio signals that include a tone sequence of the musical work generated by means of at least one musical instrument, and / or audio signals that contain a precisely a musical instrument generated tone sequence of the musical work comprise to separate.
  • This enables a musical work to be fed to the control unit, in particular in any audio format, and the control unit performs the separation of the audio signals for different sources of the musical work.
  • no prior separation or supply of already separated musical works is necessary, which enables a very high level of user comfort.
  • the playback units each include at least one amplifier.
  • a playback volume of the individual audio signals can be controlled individually and separately by appropriate control of the playback units, whereby a highlighting of certain audio signals, for example singing, and / or a receding of certain audio signals in the background, for example selected musical instruments, can be implemented. This enables an audio setting that can be individually adapted to a particular musical work and / or listener.
  • the reproduction units are controlled by the control unit in such a way that they output singing of a musical work and a tone sequence of the same musical work generated by means of at least one musical instrument, separately and in synchronism.
  • the playback units are controlled by means of the control unit in such a way that these tone sequences generated by means of a plurality of musical instruments are musical Output for each musical instrument and / or for several groups of musical instruments separately and synchronously.
  • the method enables a separate, in each case at least stereophonic, output of audio signals, so that, for example, audio signals output from different sources in a musical work can be output separately, but in a time-coordinated manner with respect to one another. This significantly improves the sound quality and, due to a demarcation between the audio signals from the different sources, the intelligibility of musical works.
  • Both the device described above and the method described above can be used not only for use in musical works but also for use in other audio signals.
  • better intelligibility of the speech and the song and an improved sound quality can be achieved through separate output of speech, song and / or sound effects.
  • the vehicle according to the invention comprises a device described above for reproducing audio signals.
  • musical works, video material and / or audio books with particularly high sound quality can be output within the vehicle.
  • the building according to the invention comprises a previously described device for reproducing audio signals.
  • musical works, video material and / or audio books with particularly high sound quality can be output within the building, for example a cinema, sound studio and other rooms.
  • the mobile terminal according to the invention comprises a previously described device for reproducing audio signals and is, for example, as Mobile phone, in particular smartphone, mobile computer or portable media player.
  • Mobile phone in particular smartphone, mobile computer or portable media player.
  • musical works, video material and / or audio books with particularly high sound quality can be output by means of the mobile terminal.
  • FIG. 1 a block diagram of a possible embodiment of a device 1 for reproducing audio signals A1 to An is shown.
  • the device 1 which is provided, for example, for an application in a vehicle and / or a building and / or a mobile terminal, for example a mobile phone, mobile computer or portable media player, comprises several playback units 2.1 to 2.n and a control unit 3 a control of the playback units 2.1 to 2.n.
  • the playback units 2.1 to 2.n each include an amplifier 4.1 to 4.n and in each case at least two loudspeakers 5.1 to 5.m for an at least stereophonic output of the respective audio signals A1 to An.
  • the respective amplifier 4.1 to 4.n and the associated loudspeakers 5.1 to 5.m of each playback unit 2.1 to 2.n can be present as separate units.
