Definitions

  • the present invention relates to an improved earphone for use with communication equipment emitting radio frequency (RF) radiation, such as cellular telephones or others, in which hazardous risks are reduced.
  • RF radio frequency
  • the RF radiation can in principle be shielded by various means, but these are heavy, cumbersome and thus not user friendly. Another drawback of such shielding arrangements is that they can interfere with the quality of reception and transmission.
  • the intensity of the radiation diminishes as a square function of the distance from the source of radiation, i.e. from the antenna. Accordingly, devices have been suggested which may be attached to the ear piece to increase distance between the antenna and the user's head. In order not to affect the hearing ability of the sound emitted from the ear piece, it has also been suggested to use a spacer with walls defining a sound channel for sound transmission from the ear piece to the user's ear. An example of such a device is that described in German Utility Model DE 97-U2-00243.
  • the invention is concerned with an acoustic earphone for retaining an earphone connected to a radio frequency transmitting device at an extended distance from the user's head whereby acoustic communication is facilitated via an acoustic tube.
  • an acoustic earphone for transmitting sound from a transducer sound source, the earphone comprising a sound transmitting tube portion extending between an ear tip member for engaging the external ear canal of a user, and a sound receiving end fitted to said sound source.
  • the sound receiving end is integrally formed or fixedly attached to the sound source. According to another embodiment, the sound receiving end is removably attached to the sound source which.
  • a typical example of the invention is an earphone connected via a wire to the mobile cellular phone.
  • either one or both of the sound source, namely earphone, and the sound receiving end is fitted with a Faraday cage providing an electrostatic shield, preventing or reducing radiation from the earphone.
  • the sound transmitting tube distances the earphone from the user's ear and head. This distance may vary between several millimeters up to several centimeters.
  • the earphone is adapted for placing adjacent a user's ear and where the housing thereof is received within a Faraday cage, typically made of a mesh wire or metallic foil, or a combination thereof, for reducing or eliminating radiation of a magnetic wave.
  • a Faraday cage typically made of a mesh wire or metallic foil, or a combination thereof, for reducing or eliminating radiation of a magnetic wave.
  • Fig. 1 is an exploded view of an acoustic earphone in accordance with the present invention detached from an earphone connectable to a communication device, the earphone comprising a Faraday cage;
  • Fig. 2 illustrates the components of Fig. 1 in their assembled position
  • Fig. 3 illustrates an acoustic earphone in accordance with the present invention, integrally fitted with a Faraday cage
  • Fig. 4 illustrates an acoustic earphone integrally fitted with an earphone connectable to a cellular phone
  • Fig. 5 is a perspective exploded view of an embodiment of the invention, wherein the earphone is entirely shielded by a Faraday cage and the acoustic earphone is different;
  • Fig. 6 is a sectional view of still another embodiment of the invention according to the present invention.
  • FIGs. 1 and 2 illustrating an acoustic earphone in accordance with the present invention, generally designated 10, and an earphone generally designated 12 of the type which is detachably connectable to a cellular phone.
  • Earphone 12 comprises an ear tip 14 with a cylindrical housing, the ear tip being formed with a Faraday cage 16 for reducing or eliminating radiation emitted from the ear tip. Extending from the ear tip there is a cord 17 fitted with a microphone 18 and a plug 20 for detachably connecting to a suitable socket of a cellular phone (not shown).
  • the earphone 12 is of standard structure as known per se, the addition being the provision of the Faraday cage 16 typically, a fine wire mesh.
  • the acoustic earphone 10 comprises a sound receiving end 26 and an ear tip 28, with an acoustic, sound transmitting tube portion 30 extending therebetween.
  • Ear tip 28 is anatomically designed for engaging the external ear canal of a user and the sound receiving end 26 is fitted with a receptacle for snugly accommodating the housing 14 of earphone 12, as can be seen in the assembled position of Fig. 2.
  • the length of the sound transmitting tube portion 30 ensures that the earphone 12 is retained at a distance from the user's head. This distance may vary, beginning several millimeters and up to several centimeters. The distance obviously depends on the length of the acoustic earphone, namely, the length of tube portion 30. In some particular embodiments, the length of the tube portion may be minimal, whereby the ear tip and the shell like portion receiving the earphone actually adjoin one another.
  • earphone 12 seen in Fig. 1 is in itself a suitable solution for eliminating or reducing magnetic radiation, as the ear tip 14 is received within the Faraday cage 16.
  • Fig. 3 is principally similar to the embodiment seen in Figs. 1 and 2 wherein the acoustic earphone designated 40 has the same general appearance as earphone 10 in Figs. 1 and 2 with the addition of a Faraday cage 42, integrally formed at the sound receiving end in the form of a fine wire mesh embedded in the shell-like receptacle portion.
  • This device is suitable for use with existing earphones and may be used as an add-on device.
  • Fig. 4 discloses an acoustic earphone 50 integrally fitted with an earphone 52, connectable by means of cord 54 to a cellular phone (not shown).
  • a Faraday cage 58 which is integrally fitted at the sound receiving end 60 of the acoustic earphone 50.
  • a sound transmitting tube 62 Extending from the sound receiving end 60 there is a sound transmitting tube 62 terminating at an ear tip 66 which is fitted with a resilient tip 68 providing improved acoustic isolation from environmental noise and for improved grip within the external ear canal of the user.
  • the ear tip 70 of earphone 72 is entirely shielded with a Faraday cage which at its ear engaging side is in the form of a mesh of wire 74 and at its other side it may be either in the form of wire mesh 76 as illustrated, or in the form of foil.
  • the acoustic earphone 80 comprises an ergonomic ear tip 82, a sound receiving end 84 in the form of a shell adapted for fixedly engaging over ear tip 70 of earphone 72 and a intermediate tube portion 88.
  • the acoustic earphone 80 is made of essentially rigid material though its ear tip 82 may be coated with a cushioning material for comfort while inserted in a person's ear.
  • the acoustic earphone 80 may be integrally formed with the earphone 72, as already explained in connection with the previous embodiments.
  • the Faraday shield portions 74 and 76 may be embedded within the structure of the ear tip 70, namely, embedded within the molded material of the structure.
  • Fig. 5 differs from the previous embodiments in that the actual length of the acoustic earphone is shorter. This however is subject to changes depending on different designs, as may be required.
  • Fig. 6 illustrates yet still another embodiment of the invention wherein the acoustic earphone 90 is integrally formed with the earphone 92.
  • the acoustic ear piece comprises a hollow rigid housing comprising an ear tip end 96 adapted to be inserted into an ear canal of the user, and a shell portion 98 fitted integrally over the ear tip 100 of ear phone 92, there being an intermediate rigid tube portion 104 extending between two ends of the acoustic earphone.
  • the Faraday cage 110 is fitted within the shell-like end portion 98 forming a radiation shield between the user's ear and the ear tip 100.
  • the assembly may be an add-on type article for use with conventional earphones or, it may be integrated with an earphone.
  • the ear tip member may be of any suitable design for comfortably and efficiently engaging the user's external ear canal for providing comfort, acoustic isolation and self retaining of the acoustic ea ⁇ hone within the user's ear.
  • a suitable auricle-attachment member may be provided for retaining the acoustic ea ⁇ hone to the user's ear.
