Definitions

  • the invention relates to a headphone with at least one decentralized arranged in a housing broadband sound transducer for reproducing a sound signal in the scope of at least substantially the entire hearing spectrum.
  • Such a headphone with decentralized sound transducer is known for example from WO 91 01 616 A2.
  • the sound transducer of this known headset is downwardly and predominantly frontwardly displaced to produce a sound event perceived by a headphone user in front of the head (front-end stereo headphone as a special case of a headphone for locating sound events outside the head of a headphone user).
  • This effect can be explained by the direction filter effect or comb filter effect of the pinna or the outer ear of a headphone user.
  • This perception of the sound event has the advantage over the in-head localization of conventional headphones with centrally located transducers per headphone housing that the user perceives the sound event in a manner that corresponds to the normal listening experience with no sound perceived sound events away from the ears of the User take place.
  • a surround sound headphone as a further development of this front-ear stereo headset with at least one additional sound transducer, which is also arranged decentrally, namely upwards and predominantly moved back (DE 42 36 765 A1).
  • this headphone sound events outside the head of a headphone user can be separated not only from the front, but also from behind and from the side of the head perceive.
  • This headphone represents the more general case of a headset to out-of-head location.
  • An object of the present invention is to provide a headphone of the type mentioned, whose playback quality is optimized with respect to the out-of-head localization of sound events.
  • a headphone with at least one decentralized arranged in a housing broadband sound transducer for reproducing a sound signal in the extent of at least substantially the entire Hörspektrums is provided as a special feature at least a high-frequency transducer for reproducing the high frequency range of the Hörfrequenzspektrums in addition to the broadband converter per headphone housing ,
  • the Hochtonschallwandler in the region of the center of the housing facing away edge of the broadband sound transducer is arranged in front of or outside of this.
  • the additional high-frequency transducer transmits the high-frequency spectrum above about 8 kHz.
  • the high-frequency sound transducer is preferably preceded by a high-pass filter.
  • the broadband transducer is arranged offset in the lower half of the housing, especially in the viewing direction of a headphone user forward.
  • the out-of-head localization in favor of a perception of sound events around the head of a headphone user is advantageously provided by another broadband sound transducer with at least one associated high-frequency sound transducer in the upper half of the housing, especially against the viewing direction of a headphone user , arranged offset to the rear.
  • FIG. 1 shows schematically a plan view of the equipped with two broadband transducers and additional Hochtonwandmin baffle (Buffer Board) of the housing of an embodiment of the headphone invention (surround headphone).
  • Buffer Board additional Hochtonwandlant baffle
  • reference numeral 1 denotes a pinna to be sounded, an earpiece or an outer ear of a headphone user
  • 2 denotes a grid-like support structure of a baffle or a buffer board of a headphone housing, not shown
  • 3 denotes an acoustically damping cover of this structure as part of the baffle or the buffer board, z.
  • FIGS. 7 to 12 denote high-frequency sound transducers positioned according to the invention.
  • the inventively positioned Hochtonschallwandler 7 to 12 are arranged in the region of the center of the headphone housing or the baffle 2, 3 away facing edge of the broadband sound transducers 4, 5 above or outside of these.
  • the high-frequency sonic transducer 9 comes to rest.
  • the Hochtonschallwandler 11 is relative to the secondary broadband sound transducer 5 to lie.
  • the Hochtonschallwandler 8 Adjacent to the edge of the primary broadband sound transducer 4, moved outside of this and in the counterclockwise direction relative to the radial arrow B, the Hochtonschallwandler 8 comes to rest. Still further in the counterclockwise direction relative to the radial arrow B shifted and at a distance from the edge of the transducer 4 is the Hochtonschallwandler 7 to lie.
  • each broadband sound transducer 4, 5 can also be assigned to a single high-frequency sound transducer. Due to their special positions, these high-frequency sound transducers serve, in their entirety or selected, the optimization of the out-of-head localization of sound events generated with the headphones, as explained in the introduction.
  • the tweeters 9 to 12 are connected in parallel to the primary and secondary broadband transducers 4, 5 by means of a high-pass filter with a crossover frequency of about 8 kHz.
