Abstract

PURPOSE:To make thin the electronic unit and to increase the efficiency of sound, by oscillating the display window glass via the piezoelectric element fixed with conductive adhesives. CONSTITUTION:The thermal setting type conductive adhesives 28 is coated at the back of the surface glass 22 of electronic unit such as watches in a given thickness and the piezoelectric element 25 providing the electrodes 26, 27 is pressed to the adhesives 28 and heated, then the element 25 is fixed to the glass 22 with the adhesives 28 and the glass 22 is oscillated via the element 25 to perform sound discharge. With this constitution, the electronic unit is made thin and the electric connection is made easy and sure, to increase the efficiency of sound discharge with the sound from the front.
