DESCRIPTION JPS5675800
Description 1, title of the invention
Electromagnetic type sweat body for watch
3. Detailed description of the invention The alarm ring is for a melody emitting a watch,
especially for a watch speaker; d, the dog of the whole watch) is limited in size and design
constraints so that downsizing and thinning are desired It has become. The object of the present
invention is to provide a compact and thin electromagnetic type sounding body based on the
above-mentioned safety device, and the structure of the present invention will be described
mainly with reference to the drawings hereinafter, mainly relating to the structure. FIG. 1 is a
main purchase reason of the sound generator for a watch of the present invention. 2 is a plan
view of the sounding body of FIG. 1. FIG. 3 is a plan view of another embodiment of the present
invention in which the permanent magnet of FIG. 1 is replaced with a pond shape. Is an
explanatory view showing an excitation winding. In FIG. 1, reference numeral 1 denotes an
acoustic diaphragm made of a magnetic material and having a thickness of 10 to 20 .mu., Which
is substantially oval and has a crown insertion portion 1cL. A magnetic plate 2 is fixed to the
center of the acoustic diaphragm and may be pure iron or an amorphous material. Reference
numerals 3 and 4 denote base plates of a magnetic material, and reference numeral 5 denotes a
frame of a nonmagnetic material. The base brazes 7 '' 3, 4 and the frame 5 constitute a sound
generator main body and have a substantially oval shape. The projections 6 and 7 are made of a
magnetic material. 8, 9 are excitation windings, and 10.11 are their lead wires. A permanent
magnet 12 is embedded in the same plane as the base plates 3 and 4 between the projecting
yokes. The company insertion part 1-a of the acoustic diaphragm 1 is inserted into the outer
peripheral part of the case 5 of the sound generator main body. FIG. 2 is a plan view of the sound
generator of FIG. 1 with the acoustic diaphragm 1 removed. In the figure, the sound producing

body of the present invention has a substantially oval shape, the projecting yokes 6.7 are
arranged in the longitudinal direction, and the permanent magnet 12 is in the shape of a square
bar and disposed in the dead space between the projecting yokes. The magnetic poles have
different polarities in the direction of the projecting yoke 6.7. FIG. 3 is a plan view of an
embodiment in which the permanent magnet of FIG. 1 is replaced by another shape, in which
three divided square permanent magnets 13 and 14.15 are disposed in the dead space between
the projecting yokes. It is set up. Although the magnetic poles are different from each other in
the direction of the projecting yoke as in the case of FIG. 2 in the above embodiment, the shape
of the permanent magnet is rectangular, but may be other shapes such as the original mold . FIG.
4 shows an excitation winding 1-99, as is apparent from the description of one or more of the
following in the inner row (with respect to the two projecting yokes 6.7). According to the
present invention, more excitation windings can be made in a limited space, and a sound
generator for a watch with low power consumption can be realized, and permanent magnets can
be effectively disposed in the dead space of the base plate of the sound generator body. The
practical effects that can be achieved are small and thin, and the practical effects are very large,
and there is an effect such as incorporating a new sense in the product.
