1. A voice sound transmitting unit having the advantage of obtaining a pure voice sound signal of a user, the unit comprising:

  • an earpiece adapted to be inserted into the external auditory canal of a user and having a bone conduction sensor and an air conduction sensor, the bone conduction sensor being adapted to operatively contact a portion of the external auditory canal adjacent the mastoid bone to convert bone vibrations of voice sound information to electrical signals and the air conduction sensor being adapted to convert air vibrations of the voice sound information in the external auditory canal to electrical signals, the earpiece being smaller in size than the interior of the external auditory canal whereby the earpiece does not block the canal;

    a speech processor operatively connected with the earpiece, the speech processor being adapted to receive the electrical signals from the bone conduction sensor and the air conduction sensor and produce a voice sound signal; and

    a transmitter operatively connected with the speech processor and adapted to receive the voice sound signal for transmission.
