Definitions

  • the present invention relates to an ea ⁇ iece preferably but not exclusively for use with a cellular phone.
  • Hands-free kits for mobile phones have been proposed in which an electroacoustical transducer earphone is placed directly in the ear of a user. It is a concern that some such portable hands-free units may assist in channelling the radio frequency energy from the mobile phone to the head of a user.
  • radio frequency energy may be linked to brain tumors, cancer, headaches and tiredness, so that use of such hands-free kits may pose a threat to the health of the user.
  • an earpiece connectable to an electroacoustical transducer, the earpiece comprising a conduit for sound connected at one end to the housing and at the other end having an ear engaging means.
  • a combination of the ea ⁇ iece according to the invention and a said transducer is also envisaged.
  • a conduit having means for engaging the ear which reduces the transfer of radio frequency radiation from the ea ⁇ iece to the ear.
  • the ea ⁇ iece comprises a sound chamber which receives an electroacoustical transducer.
  • the electroacoustical transducer converts a received electric audio power signal to acoustical vibrations inside the sound chamber and the acoustical vibrations are conducted via the tube to reach an engaging member and the ear of the user.
  • the ea ⁇ iece thus electrically isolates the user's head from the transducer.
  • the described embodiment is compact, easy to use, requires no modification of the original equipment and is relatively inexpensive.
  • the ea ⁇ iece is formed from electrically insulating material and generally comprises a rubber cover 3, a sound chamber 4, a flexible tube 5 and a hollow ear engaging member 6.
  • An electroacoustical transducer unit 2 which is connected by means of an electric conductor wire 1 to a source of electric audio power, is received in the chamber 4.
  • the chamber 4 formed from PVC or ABS and is generally of hollow cylindrical form and has two openings 9 and 12 at opposed ends.
  • the flexible rubber cover 3 is inserted into an opening 12 in the chamber 4, providing a circumferential seal at 7.
  • the flexible rubber cover 3 may be formed from another material and/or molded together with sound chamber 4 as one unit.
  • the flexible tube 5 and member 6 may be formed from PVC, rubber or the like.
  • the member 6 has a formation 13 to engage the ear of the user.
  • the connections between chamber 4, tube 5 and member 6 are a push-fit to provide an acoustical seal.
  • the electroacoustical transducer converts the signals to acoustical vibrations inside the chamber 4.
  • the opening 12 of the sound chamber 4 is fully acoustical sealed at 7 and 11, and the chamber 4 thus conducts the acoustical vibrations generating by transducer 2 through opening 9 and along flexible tube 5 to ear engaging member 6.
  • the chamber 4 is of a size to receive and hold transducer 2 snugly with the transducer face pointing towards opening 9.
  • the chamber 4, tube 5 and ea ⁇ iece 6 are otherwise empty without unnecessary reflective surfaces, to assist acoustical vibrations from the transducer reaching the user's ear.
  • the ear engaging member 6 rather than the casing of the transducer 2 is placed in the ear of the user. Sound waves are transmitted from the transducer to tube 5 through a hollow ear engaging member 6 to the user's ear.
  • the tube 5 provides a spacing between the transducer 2 and the user's head to minimise the possibility of electrical energy being transferred.
  • the sound chamber 4, the electroacoustical transducer 2 and cover 3 may be disposed inside a cellular phone or other communicating device.
  • the transducer 2, wire 1, sound chamber 4 cover 3 may be manufactured as a single unit or the transducer, chamber, wire and cover may be replaced by an acoustically sealed transducer having a formation, with an opening, which formation can be connected to the tube.
  • the ea ⁇ iece of the present invention may be used in many types of equipment in which headphones or ea ⁇ hones are used, including cellular phones, hand's free phones, two way radio transceivers, MP3 players and the like.

Abstract

L'invention concerne une oreillette pouvant être connectée à un transducteur électroacoustique utilisé comme un écouteur. Cette oreillette comprend un logement (4) conçu pour recevoir le transducteur (2), un conduit (5) pour le son dont une extrémité est reliée au logement (4) et l'autre extrémité à un élément (6) à introduire dans l'oreille. Cette oreillette isole du transducteur (2) l'oreille de l'utilisateur.
