Definitions

  • the present application relates to an in-ear headset and an in-ear handset.
  • headsets typically have one or two handsets and a gooseneck microphone attached to one of the two handsets.
  • the listeners can be configured as capsule listeners, as earaufliehren listeners or as in-ear listeners.
  • the listeners have one or more electro-acoustic transducers to reproduce audio signals accordingly. In addition to playing audio signals, listeners are sometimes used to passively attenuate environmental noise.
  • US 4,646,872, US 4,441,576 and US 4,922,542 represent a general state of the art.
  • a headset which has one or two earphones with a custom-made earmold and a gooseneck microphone.
  • the custom earmold is attached to an ear of the user.
  • a gooseneck microphone for recording audio signals is attached to one of the receivers.
  • at least one acoustic channel can be provided for receiving an acoustic filter.
  • at least one channel may be provided in the receiver for receiving at least one acoustic filter.
  • a hearing protector having standard earplugs with a channel extending through the earmuff, with an acoustic filter having noise level dependent attenuation characteristics disposed in the channel.
  • a headset is provided with at least one handset and a headset microphone, the microphone is attached to one of the handset.
  • the listener has at least one electroacoustic transducer, a rear volume and a front volume in front of the transducer.
  • At least one first channel extends from the outside through the earphone to the front volume, with an acoustic filter disposed in the first channel.
  • a mechanical filter for protection against dirt and moisture in the first channel is arranged. Due to the mechanical closure of the channel, dirt can not penetrate through the outside-in acoustic channel.
  • the arrangement of the mechanical filter in the channel provides the filter without coupling to a rear volume of the listener.
  • the filter is placed in a bypass.
  • the mechanical filter is configured to mechanically close the channel without affecting the acoustic properties of the channel.
  • a mechanical closure is guaranteed without acoustic interference.
  • the often mechanically sensitive filter can be protected from dirt and moisture.
  • the mechanical filter is configured as a fine mesh gauze, as a membrane and / or as a hydrophobic unit.
  • the mechanical filter is designed to be interchangeable.
  • dirty or dirty mechanical filters can be easily replaced.
  • the listener has an enclosed rear earphone volume that is separate from the channel.
  • the channel is connected to the volume in front of the transducer.
  • At least one microphone for active noise cancellation is located in the earphone.
  • the headset has a unit for receiving an eartip, wherein the unit has a continuous having a channel in which a mechanical filter for protection against dirt is arranged.
  • Fig. 1 shows a schematic cross section through a headset according to an embodiment of the invention.

  • the listener can have at least one microphone M.
  • the microphone M may be arranged in or on the first channel K. Alternatively or additionally, the microphone M may be arranged in a region between the channel or the bypass K and the transducer W. This microphone can be used in conjunction with an active noise reduction unit for active noise reduction.
  • the electronics for the active noise cancellation can also be arranged on the board P in the rear volume RV.
  • an in-ear earphone which essentially corresponds to the earphone shown in FIG. 1, but no headset microphone HM is attached to the earpiece.
  • Such a ausgestaltetes headset or in-ear headset and thus designed in-ear earphone can be produced in large quantities, since a custom-made Otoplast is not necessarily required. Thanks to the MF mechanical filter, the headset and the in-ear earphone can also be used where dirt and moisture are present.
  • a spatial separation of the receiver volume and the first channel K can be made possible so that acoustic and electrical functional areas (ie the circuit board P with corresponding electronics) are spatially separated from one another. which are separated. By simply replacing the mechanical filter, cleaning is easy to accomplish.

  • the electronics can also be arranged on the outside of the receiver or in a separate housing on a cable of the headset or the in-ear receiver.
  • the mechanical filters or protective filters described above can be a mass product in the hearing aid industry, so that they can be produced inexpensively.
  • the mechanical filter can also be designed by a permanently installed membrane. It should be ensured that the membrane can be cleaned in a simple manner.
  • the receiver can have a plug (not shown), by means of which the first channel or the bypass can be mechanically and / or acoustically sealed to the outside.
  • This plug is designed to be removable, so that a user himself can remove or insert the plug. Thus, further protection against increased environmental noise level can be provided.
  • a unit E is further provided, which protrudes outwards and has a second channel K1.
  • the unit E serves to receive an ear tip T.
  • the unit E has a continuous channel K1, in which a further filter F, preferably a mechanical filter, can be arranged.
  • This second mechanical filter F serves to protect against dirt (eg, earwax) or moisture, which can penetrate through the channel K1.
  • the ear tip T is preferably designed to be interchangeable, so that the earpiece can be adapted to different ear geometries.
  • an ear mold in particular a custom-made ear mold, may also be fastened to the unit E, so that the earpiece sits better against the ear of a user.
  • On the board of the microphone amplifier and possibly an active noise compensation unit can be arranged.

Abstract

L'invention concerne un microcasque comprenant au moins un écouteur (H) et un microphone (HM) qui sert à enregistrer des signaux vocaux émis par un utilisateur du microcasque. Ledit microphone (HM) est fixé sur un des écouteurs (H). L'écouteur comprend au moins un transducteur électroacoustique (W), un volume postérieur (RV) et un volume antérieur (VV) à l'avant du transducteur électroacoustique (W). Un premier canal s'étend jusqu'au volume antérieur (VV) à travers l'écouteur. De plus, au moins un filtre acoustique (AF) et/ou un microphone (M) est/sont disposé(s) dans le premier canal (K), un filtre mécanique (MF) étant disposé dans ledit premier canal pour assurer une protection contre la saleté et/ou l'humidité.
