Definitions

  • the present invention relates, in general, to an ergonomic earpiece and, more particularly, to an ergonomic earpiece which comprises a vibration system suitable for use in small sound or communication appliances, such as microphones, small audio systems and mobile phones, and can be worn in close contact with the external auditory meatus in addition to being used for a long period of time without causing inconvenience to the user.
  • small sound or communication appliances such as microphones, small audio systems and mobile phones
  • Speakers which are indispensable for sound and communication appliances, convert electrical signals into vibration energy to generate dilatational waves, thereby radiating sound waves.
  • current is sent to an electromagnet called a voice coil consisting of wire wrapped around a piece of magnetic metal.
  • an electromagnet running the current corresponding to voice signals through the coil creates a magnetic field.
  • the electromagnetic voice coil is located in the constant magnetic field of an adjacent permanent magnet.
  • Both electro- and permanent magnets are located in the center of the driver's cone.
  • the cone, or diaphragm consists of paper, plastic or pliable metal. As the current pulse and polarity changes, the electromagnet is alternately attracted to and repelled by the permanent magnetic field.
  • FIG. 1 shows a conventional undersized speaker housing 14.
  • the housing has a concave shape accommodating a vibration system, such as a diaphragm and a voice coil (both not shown) , and a plurality of holes provided at the periphery thereof, which function to reduce air resistance in the rear to assure the smooth vibration of the diaphragm, thereby showing flattened frequency characteristics .
  • the speakers embedded therein are also miniaturized.
  • the conventional speaker housing 14 suffers from problems as follows.
  • One of the determinants of speaker output is the capacity of the magnet installed in a speaker, which depends mainly on the magnet size.
  • the architecture of the holes which function to reduce air resistance upon the radiation of speaker sound so as to make sure smooth vibration of the diaphragm, is also important in determining the speaker output.
  • speakers are miniaturized with magnets of a certain capacity installed, it is difficult to form holes in the small housings. Holes, if formed, are not sufficient in number or cross section to smoothly transfer speaker sounds. Thus, suitable capacitance, speaker output and sound quality cannot be obtained.
  • FIG. 2 shows such a conventional earpiece 12.
  • the conventional earpiece 12 is in contact with the ear by being slightly put on in the external auditory meatus, so that the conventional earpiece is stably worn.
  • the earpiece cannot exhibit its performance fully as it is exposed externally.
  • another problem of the conventional earpiece is found in the body and cover surrounding the vibration system. Since the body and cover are made of synthetic resins or special metal in order to prevent deformation of the earpiece, the user suffers pain in the ear when wearing the earpiece in the external auditory meatus for a long period of time. Also, the clarity of sound is decreased because the earpiece does not tightly contact with the ear. Disclosure of the Invention

Abstract

L'invention porte sur un écouteur ergonomique (50) comportant un haut-parleur conçu pour loger un système vibrant (5) dont la taille extrêmement réduite n'affecte pas la qualité du son. Le corps (30) et la gaine (26) entourant le système vibrant (5) sont faits de silicone mou non toxique. La grande souplesse et l'élasticité du silicone rendent l'écouteur facilement adaptable à toute forme de conduits auditifs, et le coussin formé entre le haut-parleur (20) et la gaine et le corps permettent à l'utilisateur de porter l'écouteur pendant de longues périodes sans ressentir de douleur.
