Abstract

PURPOSE:To reduce size and thickness of a watch by improving integration density of a watch module, by composing a part of parts of the watch of a frame constituting a speaker. CONSTITUTION:A speaker 8 is arranged on the bottom surface of a covering member 3, and this speaker 8 is an electrically operated speaker composed of a cone 9, an annular voice coil 10, a permanent magnet 11, yoke 12 and a frame 13. And, the frame 13 is made of synthetic resin, to which outside circumference of the cone 9, on which the voice coil 10 is fixed, is attached and the permanent magnet 11 and the yoke 12, which constitute a magnetic circuit, are securely fixed. Further, one end of the frame 13 is extended and has a recess which is a liquid crystal cell positioning section 13a constituting a time indication section 2. By thus composing a part of the watch parts of a frame constituting a speaker, it is possible to reduce size and thickness of the watch.
