DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tire for an alarm
buzzer which is installed at a place where a tire pressure alarm for a car and a hot water 11 mud
water are exposed. A tire pressure warning system is generally mounted on the tire-mounted
wheel as shown in FIG. In this figure,-indicates a brake drum, and the brake drum has a bolt 3
protruding from this and a screw + screw 4 screwed to this, and the road wheel s of the wheel 1
is mounted on the wheel / Device t-do. 6 is an air valve used to inject air into the tire. -25 碌 lt
<2K't Y'7 'shaped 1'r mounting provides air pressure + torque. Melt 3 and Nara) 1 is a tire
pressure sensor and a tire pressure alarm device consisting of # 11 dry wheel rotation detection
switch, alarm buzzer, and buzzer drive circuit housed inside case 1 at the center outside of the
road wheel S Also used to attach to Pressure sensor 7tf The tire pressure is constantly received
through the air pulp weir at the time of installation shown in the figure, and this pressure switch
is closed when this value falls below the set value. When this air pressure sensor is closed, the
power of the dry cell is It is supplied to the buzzer drive circuit through the wheel (b) shift
imitation switch stuck during rotation, and the alarm buzzer can be energized by the operation of
this circuit to notify a drop in tire air pressure. By the way, the above-mentioned alarm buzzer is

usually inclined as shown by 10 in FIG. 2, and the diaphragm 12 provided with the piezoelectric
element 7 is supported by the end face opening of the case 1 by the annular rubber member 3 of
H section. It is universal. And this alarm buzzer 10 emits an alarm-sound when the
photographing moving board 12 picks up by applying a voltage through the lead wire Ia, and this
alarm sound receives the m-side board / 2. Resonant cover noII @ mouth 1 mouth 6
directionality is given to the driver. Therefore, when the vehicle is running on a rainy day or
traveling on a snowy road, muddy water intrudes into the diaphragm 12 and wears on the
diaphragm 12 when the vehicle travels on a rainy day or on a snowy road. In fact, as shown in
FIG. 2 at 17, the rotary centrifugal force of the wheel 1 causes mud to be deposited around the
annular member 3. In this case, the sound pressure level is determined because the movement of
the diaphragm 72 is restricted by the mud 17, or the volume of the noise chamber defined
between the vibration & / 2 and the resonance cover / j changes, etc. In the worst case, the alarm
buzzer 70 can not emit sufficient power, and in the worst case, it becomes inoperable. From
these points of view, the present invention proposes an alarm buzzer with measures against
muddy water by changing the shape of the base plate support member by 'mm' here.
In the present invention for this purpose, as shown in FIG. 3, the elastic annular member 13 for
supporting the diaphragm 12 has a minimum diameter at the end face on which the inner
peripheral surface / 31 L is attached to the diaphragm / 2VCMP. And II? It is shaped to expand
so as to increase the blind diameter as it goes away from the plate l-c, and the other end inner
pole of the member inner circumferential surface / Ja is made to continue smoothly at the end
face opening @ JaLK of the case l. The alarm buzzer of the present invention in which the 1113h
plate support member / 3 is shaped as described above, the muddy water to be deposited as
shown at 17 in FIG. The outer cover is moved smoothly out of the case 5 along the inner
thickened surface / jaK, and finally scattered from the resonance chamber through the opening
14 of the resonance cover 13. Therefore, there is no accumulation of mud as indicated by / 7 in
the first figure, which causes the sound pressure level to decrease due to the sedimentation mud,
which has been brewed with the conventional intelligence buzzer, and the good news buzzer
Certainly 1 button! Can be prevented. It is not necessary to use a flat surface if the inner
peripheral surface / 3a of the diaphragm support member 13 is a flat surface or if the inner
circumferential direction / JtLd is outside in the case of the preferred 1MI @ l shown. Needless to
say, even in the case of, for example, a continuous curved surface, the effects of the present
invention can be achieved.
