MANUFACTURING METHOD FOR MAGNETIC CIRCUIT FOR LOUDSPEAKER AND MAGNETIC CIRCUIT FOR LOUDSPEAKER OBTAINED BY EMPLOYING THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for a magnetic circuit for a loudspeaker used for a loudspeaker applied to various acoustic devices and the magnetic circuit for the loudspeaker obtained employing the method that can solve tasks caused by an adhesive used at assembling of the magnetic circuit. SOLUTION: In the manufacturing method for the magnetic circuit for the loudspeaker, a one-component aerobic acrylic based adhesive B is applied to a joint face between a magnet 3 and a plate 4 and a joint face between the magnet 3 and a yoke 2 through printing to enhance coating accuracy and prevent protrusion of the adhesive into a magnetic gap 1a, and the method contributes to the stability of the quality of the magnetic circuit for the loudspeaker especially for a small-sized loudspeaker.
