Abstract

PURPOSE:To make thin the watch, by enabling common use the oscillation plate and anti-magnet plate, through the use of amorphous magnetic material for the oscillation plate for sound production. CONSTITUTION:The dial 5 is pushed on the cell 1 to which the glass 2 is fixed, the oscillation plate 6 is fixed to the middle frame 3, and the back cover 7 having the hole 7a producing oscillation tone is attached to the cell 1. The piezoelectric element 17 is attached to the oscillation plate 6 to form the sound body and the oscillation plate 6 is made of amorphous magnetic material. Thus, external magnetic flux passes through the inside the oscillation plate 6 to assure the anti-magnetism of watch.
