Abstract

PURPOSE:To make a wrist watch of a thin type which generates an alarm, time signal, etc., by composing the diaphragm of a speaker of a high polymer element which is a high molecular piezoelectric body and by setting the speaker in a watch band connected to the electronic wrist watch. CONSTITUTION:As the diaphragm of a speaker used for a wrist watch having an alarming function, high polymer element 11 fitted to press plate 13, fitted to armor case 19 of the watch, via foamed urethane 12 is used. Case 10 is provided with sound holes 14 and the structure of the speaker is simplified to thin case 10 of the wrist watch. In member 23 forming watch band 22 in the same structure as watch body 21, high polymer element 11, foamed urethane 12 and press plate 13 serving as a lead wire are set to improvid the sound quality in comparison with that when the speaker is fitted to the case of the watch while thinning the structure on the whole.
