Definitions

  • the present invention relates to a headphone and a headset.
  • the use of active noise cancellation units in headphones is known, for example, from the Sennheiser HDC 451, PXC 250 and HMEC 25 headphones.
  • the background noise or ambient noise is detected by a microphone and fed to the active noise cancellation unit, whereby this background noise is compensated in such a way that the background noise is perceived only quietly.
  • Application for such noise-compensated headphones are known in the cockpit of an aircraft to suppress aircraft noise and privately usable headphones for suppressing the aircraft noise in a passenger cabin.
  • headsets with such a noise compensation can also be provided in the car in order to be able to telephone as quietly as possible in the car.
  • noise-compensated headphones are connected via a conventional headphone jack, via which the audio signal to be transmitted is transmitted.
  • This audio or external signal can represent, for example, an entertainment program or music on board an aircraft or a telephone signal.
  • This audio signal is fed in via the amplifier located in the noise compensation unit, correspondingly amplified and output together with the signals of the noise compensation unit.
  • headsets or headsets which in addition to the headphones also have a voice microphone or a boom microphone.
  • a power supply is provided either by an additional connection or by a battery supply.
  • the active noise compensation unit is connected to the headphones.
  • a headphone with an active noise cancellation unit is provided to compensate for background noise.
  • the headset has a wireless receiver for wirelessly receiving a reproduced audio signal.
  • information or audio signals may be intentionally directed to the wearer of the headset. be routed without these signals are compensated away by the noise cancellation unit.
  • both the active noise cancellation unit and the wireless receiver are housed in the same housing in or on the headphones.
  • the present invention also relates to a headset with an active Störschallkompensationstechnik for active compensation of Stör ⁇ noise. Furthermore, a wireless receiver is provided for wireless reception of audio signals to be reproduced.
  • the invention also relates to a headphone with an active Störschallkom ⁇ compensation unit for active compensation of background noise and an Informati ⁇ ons Grande for storing and reproducing audio signals.
  • the invention is based on the idea of implementing the receiver in or on the headphone or the headset, instead of an additional device for wirelessly receiving audio signals.
  • an additional device for wirelessly receiving audio signals instead of an additional device for wirelessly receiving audio signals.
  • FIG. 1 shows a schematic view of a headphone according to the first embodiment
  • Figure 2 shows a schematic representation of a headphone according to the second embodiment
  • Figure 3 shows a schematic representation of a headset according to the third embodiment.
  • FIG. 1 shows a schematic representation of a headphone K according to the first embodiment.
  • the headphone K has two earcups OM and a plug S.
  • an active noise canceling unit ASK In one of the ear cups OM, an active noise canceling unit ASK, a wireless receiver I and a playback animal W are arranged.
  • the wireless receiver I allows audio signals to be wirelessly transmitted to the headphones.
  • the plug S can be dispensed with, since now all the audio signals to be played back are received via the wireless receiver.
  • the active noise cancellation unit and a wireless Empfän ⁇ ger is realized in a common housing.
  • Figure 2 shows a schematic representation of a headphone according to a second embodiment.
  • the headphone in turn has two earcups OM, in which the playback transducer W are arranged. While in the headphone according to the first exemplary embodiment the active noise canceling unit ASK and the wireless receiver I have been realized in one of the auricles OM, these two units are implemented in an external housing G. As in the first embodiment, the plug can be omitted if the audio signals to be reproduced are received via the wireless receiver I.
  • FIG. 3 shows a headphone according to the third embodiment.
  • the headphone according to the third embodiment is basically based on the headphone according to the first embodiment.
  • an ear microphone M is also provided in the ear cup OM.
  • the ear microphone M is arranged under the noise-compensated headphone in the ear canal.
  • the voice recording of this ear microphone via the eustachian tube, which represents a connection between the mouth / throat and the inner tube.
  • the equalization unit can be arranged in the headphone / soundproof housing.
  • the active Stör ⁇ sound headphones can be used for bidirectional communication, ie a headset can be realized.
  • the ear microphone OM is used according to the third embodiment, to record the language of a user in the headset.
  • a headset can also be provided with a boom microphone instead of or in addition to the ear microphone.
  • the wireless receiver I according to the first, second and third adopteds ⁇ example can be realized wirelessly, for example, by DECT, by Bluetooth or by wireless technology.
  • the receiver I can also be implemented as a radio receiver (FM / AM / DAB / DVB-T).
  • a radio transmission receiver such as wireless headphones is possible.
  • an infrared or an ultrasonic receiver is also possible.
  • an information memory for storing audio signals may alternatively or additionally be provided.
  • Such an information memory can be used as a semiconductor memory, as a semiconductor memory. be designed with a source reduction function (AAC, MP3, etc.), as a Magnetband ⁇ memory or opto-electronic memory.
  • the information memory can be configured such that the playback from the information memory is stopped when the wireless information receiver receives a message such as a telephone call. After the end of this message, the reproduction of the audio signals stored in the information memory can be restarted.
  • the active noise cancellation unit may be shared, i. Both the noise compensation signal and the audio signals can be used by the information receiver or the information memory, so that these components do not have to be provided twice. Furthermore, a common volume control, a common power supply and / or a common housing can be provided.
  • an audio player such as an MP3 player may be provided to reproduce the audio data stored in the semiconductor memory.
  • the audio signals to be played back by the audio player may also be received via the wireless receiver.
  • a slot for a semiconductor memory card can also be provided, so that corresponding audio data can be stored in advance on the memory card and the audio data stored thereon can then be played back on the audio player, as far as the card is inserted into the slot.
  • a Vorver ⁇ amplifier By integrating the MP3 player in the above-mentioned headphones or in the above-mentioned headset, for example, a Vorver ⁇ amplifier, a power amplifier or the like can be used together by the audio player and the active noise cancellation unit.

Abstract

L'invention concerne un casque d'écoute (K) doté d'une unité de compensation du bruit parasite active (ASK) destinée à compenser le bruit parasite. Ce casque d'écoute comprend également un récepteur sans fil (I) permettant la réception sans fil d'un signal audio à reproduire. Grâce à ce récepteur sans fil (I), des informations ou des signaux audio peuvent être transmis au porteur du casque d'écoute (K) de façon dirigée ou intentionnelle, sans que ces signaux soit éliminés par l'unité de compensation du bruit parasite (ASK).
