DESCRIPTION JPS52151067
Description of the Invention Alarm watch t Standard signal generator device is electronically
divided and vibrated by an electro-mechanical converter, the first diaphragm to be produced and
the space provided to face each other An alarm watch characterized in that the second
diaphragm is provided with a waterproof structure in a buzzer having a second diaphragm
vibrated in a subordinate manner by the vibration of the diaphragm. 11. An alarm watch
according to claim 1, wherein the second diaphragm is fixed to a buzzer case with a waterproof
function and fixed to a buzzer case via a waterproof pattkin. 5. An alarm watch according to
claim 1, wherein the second diaphragm is seam-welded to a buzzer case fixed to the watch case
with a waterproof function. An alarm watch according to claim 1, wherein the first diaphragm is
fixed to the watch module and the second diaphragm is fixed to the watch case with a waterproof
function.

DETAILED DESCRIPTION OF THE INVENTION The non-invention relates to the structure of the
buzzer of an alarm watch having a waterproof function. The buzzer of the alarm watch with the
conventional waterproof function makes the diaphragm function waterproof by causing the
electric signal to be vibrated by the electric-mechanical converter and transmitting the vibration
as sound to the outside of the watch. It has a structure to prevent water from entering the watch
module inside the diaphragm. The structure is well known in which the periphery of the
diaphragm is fixed to a buzzer case or watch case via a packing. However, this structure changes
the natural frequency of the diaphragm depending on how the patch is held, and the area of the
diaphragm used for the watch must be small, and if the area is completely fixed, the natural
frequency is high. There is a drawback that it is necessary to The invention is illustrated by a
specific example, which is considered EndPage: 1 to eliminate these drawbacks. FIG. 1 is an

embodiment of the present invention. The watch case body 1 is combined with a waterproof
function through the middle pig 3 and the case pad 2 and further the sound release hole IAa1? It
is also coupled to the provided back pig 14. The buzzer frame 5 has a waterproof function on the
middle pig 3 through the buzzer pad 4 and is joined with the screw portion 5a. The S core 6
adheres to the lower surface of the coil 7 and the magnetic core 8t-and the terminal of the coil 7
fixed between the buzzer middle frame 9 and the caulking portion 5b of the buzzer frame 5 is
connected to the watch module It is done. The first diaphragm 15 of the magnetic iron piece 12
is placed on the lower step of the inner frame 9 of the buzzer and is attracted by one magnet by
the magnetic force of the magnet 8. The second diaphragm 10 is connected between the buzzer
frame 5 through the middle frame 9 and the imaging plate patch 11 so as to have a waterproof
function. FIG. 2 shows another embodiment of the present invention, and only the portions
different from FIG. 1 will be described. The second vibration-seamless plate 10t-Paskin etc. are
not directly interposed to the buzzer frame 5 to maintain direct airtightness. It is welded. FIG. 3 is
another embodiment of the present invention. The middle pig 3 is joined with the waterproof
function to the watch case body 1 via the case pad 2 with a waterproof function, and is further
joined to the discharge hole 14 and the back pig 14 provided with a hook. The buzzer frame 5 is
fixed by a magnetic core 6t force shimming portion 5 where a coil 7 and a magnet 8 are bonded
to the upper surface portion, and a first diaphragm 13t- put the magnetic iron piece 12 on the
lower step in the lower surface Is attracted by the magnet 8 and keeps its position, the lower
surface outer rim is an edge! ll5a%-Place on the middle frame 3 and insert the Pusanono Tsukin
16 together with the second diaphragm in which the outer side III is bent on the cylinder and fix
it to give a waterproof function.
FIG. 4 is another embodiment of the present invention. The upper surface of the watch case 1 is
fixed with a glass 17, and is fixed with a waterproof function along with a back pig 14 provided
with a sound emission hole 14a via a watch module 18t-case middle frame 19'li pinching case
case 2 Ru. The magnetic core 6 to which the coil 7 and the magnet 8 are adhered is fixed to the
watch module 18 by the buzzer case 5. The first vibration 'J plate with the S iron piece 12 is
placed on the lower surface of the buzzer case 5 and held in position by the suction force of the
magnet 8. On the other hand, the second diaphragm 10 is fixed by seam welding in which the
welded portion 14bK airtightness of the back pig is detected. Since the first vibration plate can be
simply supported so that its position can be detected by the suction force of the magnet by
taking the structure as described above, the vibration is stabilized, and the frequency due to
manufacturing variations In addition, it is possible to reduce the vibration frequency lower than
the one that would fix the periphery of 4 with a small area shooting plate. In addition, in order to
perform the waterproof function with the second diaphragm, there is an effect that it can be used
even with a material having relatively low corrosion resistance. On the other hand, unlike the
first diaphragm which is directly vibrated, the second diaphragm is easy to manufacture because
it has little influence on the variation in manufacture and the volume and the like due to the
peripheral fixing.
