Sound emitting device for electronic timepiece

An electronic timepiece comprising:

• a disk-shaped permanent magnet;
• at least one yoke introducing magnetic flux produced by said magnet and forming, outside the periphery of said magnet, a magnetic gap having the magnetic flux in the vertical direction of the perimeter of said magnet and in the horizontal direction of the disk surfaces of said magnet;
• a diaphragm carrying, within the magnetic flux of the magnetic gap, a moving coil wound at right angles to said flux and adapted to be vibrated by the electromagnetic force received from said magnetic flux in response to variations in signal currents sent from a circuit block to said coil;
• a support member supporting said permanent magnet and said yoke as well as said diaphragm at the diaphragm peripheral portion and secured removably at the support member peripheral portion to a timepiece case, a plurality of openings being provided in a part of said support member except where said permanent magnet, yoke and diaphragm are supported, and said support member forming an air chamber which opens to the back of said diaphragm;
• a means for securing removably said support member to the case;
• a circuit means sending the signal currents to the moving coil;
• and
• a guard member locked on the surface of the case.
