Definitions

  • the present invention relates to a headphone system, and relates particularly, though not exclusively, to lightweight compact headphones for mobile use.
  • a known headphone system having an integral source of music signals is disclosed in US 5,640,458.
  • headphone systems which include an integral source of audio signals.
  • headphone systems including a receiver for radio broadcasts are known, but the headphones in such systems cannot be used with other sources of audio signals, such as a MiniDisc® player or the MP3 player described in US 5,640,458. They are also bulky.
  • the headphone system disclosed in US 5,640,458 is a dedicated system which cannot be used to listen to other sources. Further, only about 30 minutes worth of programme can be held in the semiconductor memory described in US 5,640,458, which would not be long enough for a long-haul flight, for example.
  • the present invention shown in Figure 1, comprises a headphone system, having a pair of loudspeakers (1,2) coupled to a headband (3), in the present example a horseshoe or U shape made of a resilient material, which is integrated with a removable securable cartridge system (4), where the cartridge is a music/sound source which is interchangeable, so that for example an MP3 player cartridge can be exchanged for another with different programme material stored in it, or exchanged for a radio receiver or a MiniDisc® player.
  • the sound/source cartridge can be one of several types, for example :-
  • radio link option b) above would be useful for electronic musical instrument applications, where a musician wishes to practice a "silent" instrument and listen to the synthesised sounds via headphones, and for a cordless interface to aircraft entertainment systems.
  • the MP3 player option c) is also valuable in non-domestic applications, such as the "Audio Guide", where the unit is used to guide visitors around a place of interest, and also provide an informative commentary, cued by location.
  • MP3 cartridges may be loaded with different language options, or different levels of detail for example, such that the headphone system of the present invention can be loaded with custom material for different users.
  • a major advantage of the cordless aspect of the invention will be in aircraft.
  • Current headphone cables interfere with activities such as eating, reading, leaving the seat, and so on.
  • the audio source is integrated with the headphone system, however, there is no cable with which the user can become entangled.
  • the headphone system of the present invention has a number of advantages.
  • the system is flexible, because a user can for example use one cartridge whilst at home and another whilst travelling.
  • the headphones are lightweight, because only a single source is carried by the headband at any given time. The user need purchase only those cartridges they require, and the user does not need to purchase an additional set of headphones with each new function.
  • a mobile phone cartridge and a microphone or a TV tuner cartridge and a head mounted display unit. It is also possible to include digital signal processing circuitry to provide enhanced audio or virtualised surround sound etc. It is also simple to include an external noise cancellation system into the headphones, such that external noise is detected by an externally mounted microphone and cancelled by electronic subtraction, which is well known in the art.
