Abstract

PURPOSE:To form easily a means for measuring pressure, by sticking a strain sensor into an electroacoustic transducer. CONSTITUTION:An electroacoustic transducer is constituted of a lower yoke 8, a coil 9, a magnet 10, a resonance plate 7 for forming a double diaphragm, a sounding plate 5 and a diaphragm supporting frame 11 for supporting them, and when sounding, an electric signal is converted as vibration of the resonance plate 7 first, its vibration is transmitted to the sounding plate 5 through an air chamber 12, and is transmitted as a sound into the air through a sounding hole 4. When said strain sensor 6 is tuck to the inside of the sounding plate 5, water pressure is transmitted to the sounding plate 5 through the sounding hole 4 in the water. The sounding plate 5 is bent toward the air chamber 12 in accordance with water pressure, and an output of the stuck strain sensor 6 is varied in accordance with pressure. In this way, it is unnecessary to install newly a pressure sensor onto the surface of a wrist watch, a limit by dimensions is eliminated, and the existing airtightness and durability can be maintained in respect of its structure.

Description

[Detailed description of the invention] The present invention relates to an electronic wristwatch with a pressure sensor,
Specifically, they are an electronic wristwatch Kv equipped with a function of detecting pressure by using a strain sensor in an electroacoustic transducer.

The only information about pressure Kp- in the environment surrounding us that is directly effective in our lives is information about V pressure and water pressure.

If you are able to use the power pressure, you can apply the last total π to the ship, and know the change in the fire pressure.
There are 7. Regarding water pressure, a multi-π depth gauge is recommended for use, and is indispensable for divers. However, since this is a modern search belt, there is no pressure detection method that anyone can use, and it is inconvenient to use it because it is impossible to obtain information on Takama and ice deep pipes. 7 blamed.

The object of the present invention is to use the 'F-Kunne Il!' which is used in electronic wristwatches. The object of the present invention is to provide a means for measuring the pressure of the Heyi River by pasting a sensor in the exchanger.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a top view of oil FN according to an embodiment of the present invention.

Except for the fact that the sound emitting plate 5π distortion sensor + 6 is pasted, it has a six-dimensional structure, and it has a double diaphragm at the current size. No.Here, the electric sound box yIf converter consists of 8 lower yoke irons, 19 coins, and 10 magnets.
Consisting of a sounding board 7, a sound emitting board 5, and a diaphragm support frame 11 supporting them, which form a double diaphragm, the electric signal is pushed as the vibration of the sounding board 7 when sound is produced. ,
The vibration is transmitted to the sound emitting plate 5 through the empty room 12,
As sound through sound emission hole 4! I can convey it to you. glass 1
, the voice button 3, and the sound plate 5 are equipped with a pariquin.

The electrical sound transducer with a double diaphragm has the advantage of having excellent electrical characteristics compared to the W acoustic transducer with a single diaphragm, and has a structure that can withstand high force. She has a sexual characteristic of being stubborn, and is actually 10Q.

There are 4#ζh in use that cannot withstand water depths under N. When mounting a pressure sensor → on a watch VC, the mounting method and the structural shape of the watch body are always important! vl
However, the present invention in which the φ-sensor 6 is attached to the inside of the sound emitter 1#5 does not impair the sealability and robustness of the prior art. In this article, we will discuss the detection of water pressure. In the underwater fender, water pressure passes through the sound emitting hole 4 and reaches the sound emitting plate 5.
The missionary is leaked.

The sound emitting plate 5 moves toward the air chamber 12 according to the water pressure and emits sound.
The skewer force of the strain sensor 6 attached to Fi5Vr is the pressure fF.
Do! I'm going crazy.

Chiku 2M is a block diagram of an embodiment of the present invention. Distortion Ten-1
+6 power 2, lightning boil, voltage, etc. Ah, that-!
Get used to converting logical data f using the V-circuit 13. By this data 4 conversion circuit 14, the water depth can be displayed.
After being converted to F, it is shown on the display 19KF via the lever/driver 18.

The clock function consists of counting pulses from the oscillation circuit 15 through the dividing circuit and path 16 by the counting circuit 17, passing through the decoder/driver 18, and displaying the time on the IH+91c.

The present invention is characterized by the fact that the electronic clock has six double diaphragms than the conventional one, and the W air sound + cost converter is used as a part of the pressure sensor. Because of this, it is necessary to add a new ftK pressure sensor to the watch table 4! No P, thick f
It is very frustrating to be able to eliminate the limitations caused by k and still maintain the airtightness and robustness of the structural IC1i #tf
Effect 7'I no Afu. In addition, the cost is 7'+ because it is difficult to complete the structure! It's hard to miss the benefits of saving money, *IQFifiK, pressure +Y
You can easily obtain T-information and wear it with pressure gauge, high guest gauge, water depth gauge, etc., while traveling or mountain climbing.

Widely used for diving and other activities -2! Although it is easy to draw, the effect of the light is great.
