Definitions

  • the invention relates to apparatus for emphasising sounds and in particular, apparatus which helps to filter out background noise.
  • apparatus for emphasising sounds comprises a member having a concave surface which defines first and second adjacent openings, the plane defined by each opening being at an angle to the other, whereby the apparatus may be put on an ear of a user so that the ear projects into the first opening and sound waves entering the second opening are reflected from the concave surface towards the first opening and into the ear.
  • the angle is approximately a right angle and typically, the second opening is directed in a generally forwards direction when the apparatus is placed on the ear of the user.
  • the member is in the form of a sheet of material which may be formed from a metal, a plastic, a foam material, paper or any other suitable material.
  • the apparatus comprises a pair of such members.
  • the concave surface is defined by a locus of points which are all substantially the same distance from a given, imaginary point.
  • the surface could be formed from a portion of an ellipsoid, or be plurality of abutting planar surfaces which together define a generally concave surface which may be a portion of a polyhedron.
  • the or each member defines a surface which is generally one quarter of the inside surface of a spherical shell.
  • the apparatus includes a strap, the pair of members being connected one at each end of the strap so as to form a head set similar to a pair of headphones.
  • the apparatus further comprises a head-band which can be put horizontally on and around the head of the user.
  • a connecting portion on each member to connect each member to the head-band.
  • the connecting portion may detachably connect each member to the head-band.
  • the apparatus may be included into a hat, such as a baseball cap so that the apparatus depends from the lower edge of the hat.
  • the apparatus may also include a neck-band to provide further securement of the apparatus onto a user.
  • the apparatus may further comprise retaining means attached to the or each member which engages with the ear of the user to retain the apparatus on the ear. This could be provided by the inherent resiliency of the member which could enable it to be "clipped" into place on the ear of a user.

  • a member 1 which has a concave inner surface 2.
  • a mounting hole 3 is provided externally on the member 1.
  • the surface 2 is defined by the inner surface of a quarter segment of a spherical shell. That is, the surface 2 is defined by a locus of points which are all equidistant from a centre.
  • the member 1 has two edges 20, 21 which are at approximately 90° to each other. One edge 21 has a strip of padding 9 attached to it.
  • two members 1 are connected by a head strap 4 so as to form a head set similar to a pair of headphones.
  • the strap 4 has engaging lugs 22 which engage with the holes 3.
  • a user can put one member 1 of the apparatus on each ear by placing the padding 9 against the skin around the ear, so that the edge 20 and the head of the user define an opening 8 which faces generally forwards.
  • a signal of interest to the user will enter the opening 8 and is reflected by the inner surface 2 into the ear, and at the same time, the member 1 will keep away the background noise from other directions.
  • Such apparatus for emphasising sounds could be used by an audience in a concert hall or theatre, the opening 8 and inner surface 1 assisting the audience to collect the signal of interest from the stage, and prevent or reduce the noise from behind or other areas. This principle is shown in Fig. 5.
  • Figs. 3 and 4 show a second example of the apparatus for emphasising sounds as a head-set which comprises a ring-formed head band 6 and a connecting item 5 on each member 1.
  • the ring-formed head band 6 could be put horizontally on the head of a user, the members are connected with the strap 6 by the recess 7 in the connecting item 5. Each member may be moved along the strap 6 so as to choose the proper position.
  • Figs. 6A and 6B show a modification to the apparatus shown in Figs. 1 and 2.
  • the members 1 are interconnected by a head strap 4 and two head adjustment straps 10, 11.
  • the adjustment straps 10, 11 are provided with ratchet notches 12 which co-operate with a corresponding ratchet mechanism (not shown) within the headband 4. This enables the height of the headband 4 to be adjusted relative to the members 1 for users with different sized heads.
  • the adjustment straps 10, 11 are connected to the members 1 at their uppersides by means of split rivets 13 which co-operative with a recess formed in a connector 14 which is formed on the outside surface of each member 1.
  • Fig. 7 shows an exploded view of the fixing system shown in Figs. 6A and 6B in which the split rivet 13 has a lug shoulder 18 formed at its lower end and a split 19 in its lower end to enable flexing of the shoulders 18 relative to the main body and top of the rivet 13.
  • the rivet 13 secures the adjustment strap 16 to the connector 14 by passing through a hole 25 in the adjustment strap 10.
  • the shoulders 18 may flex towards each other due to the split 19 in the rivet 13.
  • the shoulders 18 then engage in a recess 26 within the connector 14 to secure the adjustment strap 10 to the member 1.
  • Similar connectors 14 are formed on the bottom side of each member 1 to enable a neck strap 15 and neck adjustment straps 16, 17 to be coupled to the members l by means of a split rivet 13.
  • the neck adjustment straps 16, 17 also have ratchet notches 12 formed onto their surface which engage with a ratchet mechanism (not shown) within the neck strap 15. This enables the neck strap 15 to be adjusted to suit different users.
  • the addition of the neck strap 15 has the advantage of providing a more secure fit of the members 1 on a user.
  • FIG. 8A and 8B A modification of the apparatus shown in Figs. 3 and 4 is shown in Figs. 8A and 8B.
  • the apparatus is similar to the apparatus shown in Figs. 6A and 6B except that the head strap 4 and head adjustment straps 10, 11 have been replaced by two headbands 30 which are interconnected by two head band adjustment straps 31, 32 which are connected to the member 1 by the split riveting system shown in Fig. 7 and described above.

  • FIGS. 9A and 9B show a moulded helmet 40 which has the members 1 moulded into the helmet 40 and padding 41 around the inside of the members 1, within the helmet 42.
  • An aperture 42 is formed in the helmet adjacent each member 1 and padding 41 to permit sound to be reflected from each member 1 into the ear of a user.
  • Figs. 10A and 10B show a member 1 which has been moulded into a sheet of material 45 and which is provided with two fixing apertures 46.
  • the device shown in Figs. 10A and 10B enables the members 1 to be retrofitted to an existing piece of headwear, such as a sports helmet or to enable the members 1 to be detachably connected to a piece of headwear, for example to enable them to be easily replaced or to enable them to be used with the piece of headwear when desired.
  • Figs. 11A to 11D show a modified member 51 which incorporates an insulation layer 52 which covers the exterior surface of relatively ridged inner member 53.
  • the insulation 52 extends around the edge of the member 51 to additionally provide the padded section 9 which sits adjacent to the ear.
  • the insulation 52 may be provided in order to help damp out extraneous sounds from behind or to the side of a user to help a user concentrate on the sounds emanating from the direction in which a user is facing.
  • the member 1 could be incorporated into other retaining devices, for example, it could be included into a hat, such as a baseball cap. This may be used for sports to cut out the background noise for both participants of the sports and spectators. This enables both competitors and spectators to pay full attention to the respective sport.
  • the invention could also be used for hunting, military applications, and rescue operations to enable the user to concentrate fully on what he is doing.

Abstract

Appareil d'accentuation du son comprenant un élément (1) doté d'une surface concave (2) délimitant deux ouvertures voisines (8). Le plan délimité par chaque ouverture forme une angle tel avec l'autre ouverture que lorsque l'appareil est mis en place sur l'oreille de l'utilisateur de telle sorte que l'oreille s'engage dans l'une des ouvertures, les ondes sonores pénétrant dans l'autre ouverture (8) sont réfléchies par la surface concave (2) en direction de la première ouverture, d'où elles entrent dans l'oreille.
