A preprocessing apparatus of a sound converter is provided to stabilize a sound output characteristic by standardizing a preprocessing operation of a vibration plate and a coil unit. An outgoing line of a coil unit has a specific form in a vibration plate. The coil unit is mounted on the vibration plate. The vibration plate generates the sound pressure. A jig base(110) fixes the position of the vibration plate. A jig plate(130) guides the form of the outgoing line. After the form of the outgoing line is guided, a connection member(120) separates a jig base and a jig plate. |
