    DETAILED DESCRIPTION OF THE INVENTION
  • The helmet of the present invention comprises a shell (1) and on each of its sides, where the ears of the user are usually located, an internal structure (3) and an external structure (2). These structures recreate the acoustic form of human ears. The helmet also comprises a viewing hole in the shell (1).
  • The internal structure (3) is arranged inside the helmet, while the external structure (2) is disposed on the outside thereof and the two are coupled with the shell (1). Both internal and external structures (2 and 3) comprise hearing holes, which are aligned with a hearing hole of the shell (1), when said structures are coupled to the shell (1), allowing the entry of sound from the outside.
  • Particularly, the internal structure (3) may comprise an ear pad (4) and a cone (5).
  • The external structure (2) may comprise an ear-shaped element (8) and optionally a liner (9).
  • The cone (5) may comprise a coupling trumpet (10) to the ear pad (4). The ear pad (4), the trumpet coupling to the ear pad (10) and the cone (5) each comprise a hearing hole. The hearing holes are aligned when the internal structure (3) and the external structure (2) are assembled to the shell (1).
  • Particularly, the trumpet (10) is inserted in the hearing hole (13) of the ear pad (4), to couple said pad (4) to the cone (5).
  • In a preferred embodiment of the invention, the cone (5) and the trumpet (10) are made of a ductile material, which makes it possible to deform the trumpet (10) to insert it into the hearing hole (13) of the ear pad (4). Preferably, the ductile material may be silicone.
  • The ear-shaped element (8) comprises a hearing hole, which is aligned with the hearing ports of the ear pad (4), of the coupling trumpet (10) to the ear pad (4), of the cone (5) and the shell (1), when joining with the latter.
  • The ear-shaped element (8) can comprise holding structures (11) on its internal face. The cone (5) may comprise connecting holes (15) for receiving the fastening structures (11). Likewise, the shell (1) can comprise coupling holes (12) through which the fastening structures (11) of the ear-shaped element (8) pass, thus coupling both the cone (5) and the element in shape of ear (8) to the shell (1).
  • In a preferred embodiment of the invention, a filter (6) can be disposed within the hearing hole (16) of the cone (5).
  • Additionally, a piece of fabric (7) can be inserted into the hearing hole (14) of the shell (1) and into the hearing hole (17) of the ear-shaped element (8), said piece of fabric being also adhered to the hearing hole (16) of the cone (5). Optionally, the piece of fabric adheres to the cone (5), on top of the filter (6).
  • The external structure (2) may comprise a lining (9) on the ear-shaped element (8), to protect it from rain and foreign elements. The liner (9) can be fastened to the wall of the internal part of the ear-shaped element (8), for example by means of an adhesive.
  • All of the hearing holes (13, 14, 16, and 17) are aligned, and are arranged perpendicularly to the user's ear canal.
  • The sound signal enters through the external structure (2) and transduces acoustically to the cone (5). Subsequently, the trumpet (10) transmits the sounds to the user's ear, generating also a closure of the signal. Therefore, the ear accommodates the perception by psychoacoustics and perceives the relative location and distance of the sound sources. Thanks to the size of the cone that is attached to the ear of the user, it is possible to increase the perception of the audible and directional frequencies, which generate the perception of location and distance more easily for the user.
  • In a preferred embodiment of the invention, the ear pad (4) can be made of imitation leather, the filter (6) can be of windproof foam, the piece of fabric (7) can be stuffed, the shell (1) can be made of polycarbonate, the ear-shaped element (8) can be made of silicone and the lining (9) can be made of a fabric that is resistant to heat and UV rays. However, this list is not limiting and similar materials may be employed.
