  • the magnetic force line of the magnet 240 may be directed to the voice coil 220, both the upper surface and the side of the magnet 240 is covered with one cover 250 and to the left and right sides of the cover 250 Bolt 265 is coupled with lid 270.
  • the cover 250 is preferably formed of a metal material that cannot be penetrated by the magnetic force line so that the magnetic force line of the magnet 240 can be concentrated toward the voice coil 220.
  • the bone conduction speaker 200 operates as follows. First, a current signal corresponding to a predetermined voice signal is transmitted to the voice coil 220. Then, the voice coil 220 is vibrated at a predetermined frequency by the repulsive force or attraction with the magnet 240, the pole piece 212, the curved surface 214. In addition, at this time, the diaphragm 230 located above the voice coil 220 is vibrated together by the vibration from the voice coil 220. In addition, the diaphragm 230 has a plurality of long holes 234 formed therein, so that the diaphragm 230 vibrates in a more amplified form than the voice coil 220.
  • the vibration phenomenon of the diaphragm 230 is transmitted to the scalp of the human body through the magnet 240 and the cover 250 mounted thereon. Then, even if the hearing impaired person has an abnormality in the eardrum or the osseous bone in the skull of the human body, the sound can be surely heard if the cochlear or auditory nerve is normal.
  • the bone conduction speaker 200 is made of a case 210, a voice coil 220, a diaphragm 230 and a magnet 240, as described above, the components are minimized and light weight. Of course, the manufacturing process is thus simple and the manufacturing cost can be reduced.
  • the magnet 240 is not installed inside the case 210 or the side of the voice coil 220, but is installed on the case 210 and the upper portion of the voice coil 220, so that the size of the bone conduction speaker 200 as a whole. Can be significantly reduced. That is, the bone conduction speaker 200 is miniaturized. Therefore, the bone conduction speaker 200 according to the present invention can be easily connected to and used in small electronic devices such as mobile phones, PDAs, and MP3 players.
