Abstract: A coupling structure of a signal converting apparatus comprises: a frame having at least two coupling protrusions horizontally formed at an outer circumference thereof; a coupling member for coupling the signal converting apparatus; and a cylindrical coupling body being formed at an upper face of the coupling member and having horizontal and vertical cuts in a certain shape to correspond to the coupling protrusions wherein the coupling protrusions are inserted into a cylindrical coupling body of the coupling member, is rotated by a selected angle and is latched on the vertical and horizontal coupling grooves of the cylindrical coupling body such that the coupling member is integrally coupled to the signal converting apparatus.

Abstract: A signal converter used in various electronic communication products saves power consumption and prolongs the time for usage thereof by its structural characteristics. The signal converter functions as a vibrator, a speaker, and a receiver, etc. together, and generates vibration or sound by magnets installed such that a repulsive force or an attractive force generated from magnets and excitation coils is directed to the same direction so as to remove an inefficient functional operation.
