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 make calls in the car with as little interference as possible.
  • noise-compensated headphones are connected via a conventional headphone jack, via which the Au audio signal to be transmitted is entered.
  • 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, amplified accordingly 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.
  • US 6,567,524 B1 shows a handset with a microphone, an active noise cancellation unit and a wireless receiver.
  • the noise cancellation unit and the wireless receiver may be arranged in a common housing.
  • US 2001/0046304 A1 shows a headset with a microphone, an active noise compensation unit and a wireless receiver.
  • the noise compensation unit and the receiver may be arranged in a common housing.
  • EP 1 094 685 A2 shows a headset with a microphone, an active noise compensation unit, a wireless receiver and an information storage.
  • the noise compensation unit and the wireless receiver may be arranged in a common housing.
  • a headset is provided with a microphone and an active noise cancellation unit to compensate for background noise.
  • the headset includes a wireless receiver for wirelessly receiving an audio signal to be reproduced. Both the active noise cancellation unit and the wireless receiver are housed in the same housing in or on the headset.
  • the headset also has an information storage for storing and reproducing audio signals, the information storage having at least one reproduction converter for reproducing the stored audio signals or the audio signals received by the wireless receiver.
  • the information store is configured to stop playback from the information store when the wireless receiver receives a message.
  • information or audio signals can be intentionally forwarded to the wearer of the headset without these signals being compensated away by the noise canceling unit.
  • the invention is based on the idea of implementing the receiver in or on the headset instead of an additional device for wireless reception of audio signals.
  • an additional device for wireless reception of audio signals Only a single device for active noise cancellation and for wireless reception must be provided, which increases the comfort.
  • FIG. 1 shows a schematic representation of a headphone (K) according to a first example.
  • the headphone (K) has two earcups (OM) and a plug (S).
  • an active noise cancellation unit (ASK) In one of the earcups OM an active noise cancellation unit (ASK), a wireless receiver (I) and a playback transformer (W) is arranged.
  • ASK active noise cancellation unit
  • I wireless receiver
  • W playback transformer
  • audio signals can be wirelessly transmitted to the headphones.
  • the plug (S) can be omitted since now all the audio signals to be reproduced are received via the wireless receiver.
  • the active noise cancellation unit and a wireless receiver is realized in a common housing.
  • FIG. 2 shows a schematic representation of a headphone according to a second example.
  • the headphone in turn has two earcups (OM), in which the playback transducers (W) are arranged. While in the headphone according to the first example, the active noise cancellation unit (ASK) and the wireless receiver (I) have been realized in one of the ear cups (OM), these two units are implemented in an external housing (G). As in the first example, the plug may be omitted when the audio signals to be reproduced are received over the wireless receiver (I).
  • ASK active noise cancellation unit
  • I wireless receiver
  • FIG. 3 shows a headphone according to a third example.
  • the headset is essentially based on the headphone according to the first example.
  • an ear microphone (M) is also provided in the pinna (OM).
  • the ear microphone M is placed under the noise-compensated headphone in the ear canal.
  • An electrical equalization necessary for good speech intelligibility i. Frequency response adjustment, dynamics control and dynamic compression of the ear microphone (M) signal are also implemented together with the Active Noise Compensation Unit (ASK).
  • the equalization unit may be disposed in the headphone / noise enclosure housing.
  • the active noise canceler can be used for bidirectional communication, i. a headset can be realized.
  • the ear microphone (M) used to record the language of a user in the headset.
  • the use of the ear microphone also reduces a problem of biological feedback from a person. People who wear noise-compensated headphones sometimes have a lower voice, since they perceive themselves to be significantly quieter and therefore have no reason to speak louder.
  • a headset can also be provided with a boom microphone instead of or in addition to the ear microphone.
  • the wireless receiver (I) can thereby be realized wirelessly, for example, by DECT, by Bluetooth or by WLAN technology.
  • the receiver (I) may 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.
  • the invention additionally provides an information memory for storing audio signals.
  • an information memory can be used as a semiconductor memory, as a semiconductor memory with a source reduction function (AAC, MP3, etc.), be designed as a magnetic tape memory or as opto-electronic memory.
  • the information storage is configured to stop playback from the information storage 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.
  • certain components such as a preamplifier, a power amplifier, or the like, may be common to each other. be used for both the noise compensation signal and the audio signals from the information receiver or the information store, so that these components need not be provided in duplicate.
  • a common volume control, a common power supply and / or a common housing may be provided.
  • the 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 may also be provided so that corresponding audio data may 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 preamplifier, a power amplifier, or the like can be commonly used by the audio player and the active noise canceling unit.
