Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wristwatch with a calling device for calling a person who receives a calling signal from the outside.

[0002]

2. Description of the Related Art Conventionally, as means for calling a person who receives a calling signal from the outside, there is a means for causing mechanical vibration by rotating a block piece eccentrically by driving a motor, thereby stimulating the skin. .

[0003]

[Problems of the prior art] One of the problems in the skin stimulating means according to the prior art is that mechanical vibration for causing skin irritation cannot be perceived unless the stimulus intensity exceeds a certain level. Therefore, the block piece that generates mechanical vibration must have a certain size and weight,
Along with this, the electromagnetic motor as a drive source must have a certain output or more. However, it is extremely difficult to meet the above requirements due to the size and weight restrictions required for a wristwatch.

The second problem is that the battery as a power source is consumed very quickly because it is necessary to drive an electromagnetic motor having a constant output or more. As a result, battery replacement is frequent, and if the battery is near the end of life, it may not function as a calling device.

[0005]

The present invention has been completed to solve the above-mentioned problems of the prior art. That is, even if a calling device is attached, the wristwatch with a new calling device is provided, which does not substantially increase the size and weight of the wristwatch and enables the life of the battery to be extended.

[0006]

The present invention will be described below with reference to the drawings. As shown in the block diagram of FIG. 1, a calling device for a wristwatch with a calling device according to the present invention includes a calling signal receiving unit 1 that receives a calling signal from the outside and a vibration generating unit that receives the signal and generates mechanical vibration. 3 for supplying power to the piezoelectric vibrating body. However, the specific means for solving the above problems are as follows.

The first means is a back cover of a wristwatch with a calling device, as shown in FIGS. 2 and 3, a back cover 5 having a diaphragm function and a back cover having no diaphragm function, that is, a non-equipped back cover. The structure in which the piezoelectric vibrating body 8 is fixed to the inner surface of the back cover 5 having the diaphragm function tool and the outer surface of the back cover 5 having the diaphragm function tool are provided with one or more protrusions. It is something that can be done from the configuration.

In the above-mentioned structure, the back cover is not a so-called integral body but is divided into the back cover 5 having the diaphragm function and the back cover 4 not having the function. The reason is as follows. That is, a large amount of electric energy is required to mechanically vibrate the so-called one-piece back cover that does not separate, whereas when the separation mode is adopted, only a part of the back cover is mechanically oscillated. This is because it is sufficient to vibrate, and therefore, much less electric energy is required.

Therefore, in the present invention, since the back lid 5 having the diaphragm function and the back lid 4 not having the diaphragm function are configured as one back lid, the boundary between the back lid 5 having the diaphragm function and the back lid 4 not having the tool. A vibration damping member 6 made of a soft metal such as indium or aluminum, rubber, a polymer material or the like is interposed in the portion.
The damping member 6 is provided in order to maintain airtightness inside and outside the wristwatch and to prevent mechanical vibration generated in the case back 5 with the diaphragm function from being transmitted to the case back 4 without the diaphragm function on the outer periphery thereof. It has been done.

The piezoelectric vibrating body 8 fixed to the inner surface of the back cover 5 having a vibrating plate function is made of a material such as lead zirconate titanate having a high piezoelectric property, and its shape is disc-shaped, square-plate-shaped or the like. It is a thin plate with a shape. Then, the piezoelectric vibrating body driving electrodes 9 are formed on both the front and back surfaces of the piezoelectric vibrating body 8 by appropriate processing such as silver baking so as to align the dipole polarization of the piezoelectric vibrating body by polarization treatment, vacuum deposition, or the like. .

The piezoelectric vibrating body 8 is fixed to the back cover 5 having a vibrating plate function by interposing an adhesive layer, a film having adhesiveness, or the like therebetween. Therefore, in order to faithfully transmit the vibration of the piezoelectric vibrating body 8 to the back cover 5 having the diaphragm function tool without loss, it is desirable that the thickness of the adhesive layer and the film is as thin as possible.

One or two or more protrusions 7 are provided on the outer surface of the back cover 5 having the diaphragm function tool. The protrusion 7 is provided in order to surely and sharply stimulate the skin, and a protrusion height of 2 mm or less is sufficient.

The second means is, as shown in FIGS. 4 and 5, a structure in which the projection 7 is not attached to the back cover 5 having the diaphragm function tool in the wristwatch with the calling device, and other structures are the same as those of the first embodiment. It is the same as the means. However, the second means does not attach the projection 7 in order to prevent the skin from feeling uncomfortable.

The third means is, as shown in FIGS. 6 and 7, in a wristwatch with a calling device, unlike the first means and the second means, the back lid is a back lid having a vibrating plate function component and the non-equipment. Of the back cover 5, which is not separated from the back cover 5, and a structure in which the piezoelectric vibrating body 8 is fixed to the inner surface of the back cover 5.
One or two or more protrusions 7 are attached to the outer surface of the.

Unlike the first means and the second means, the third means is a back lid which is a unitary piece which is not separated.
Easy to assemble. The other structure except the back cover 5 is the same as the first means.

The fourth means is the same as the third means except that the protrusion 7 is not attached to the wristwatch with a calling device as shown in FIGS. 8 and 9. The fourth means is to further simplify the structure and to make the skin feel uncomfortable than the third means.

[0017]

Operation: The operation of the calling signal receiving section 1 upon receiving the calling signal, and the operation of the piezoelectric vibrator driving power supply section 2 based on the operation.
The piezoelectric vibrating body 8 generates a bending vibration by receiving a drive voltage to the vibration generating unit 3 in response to this. By the way, since the piezoelectric vibrating body 8 is fixed to the back lid 5 having the diaphragm function tool,
In response to the flexural vibration of the piezoelectric vibrating body 8, the back cover 5 with the diaphragm function implements the flexural vibration integrally with the piezoelectric vibrating body 8, and accordingly the projection 7 is attached to the back lid 5 with the vibrating plate function. In the case of the structure described above, the protrusion 7 causes vertical vibration in conjunction with the bending vibration of the piezoelectric vibrating body 8. Protrusion 7 here
As long as it is in contact with the skin, the vibration of the up-and-down movement of the protrusion 7 causes skin irritation and makes the call signal receiver feel that the call signal is emitted from the outside.

[0018]

The wristwatch with a calling device according to the present invention has the above-described structure and operation. The first effect of the present invention, however, is that the reception of the calling signal is surely felt because the reception of the calling signal is notified by the direct skin stimulation.

The second effect is that the conventional calling device is used as a single device by putting it in a pocket of clothes or the like, and the human body has a feeling of oppression. On the contrary, in the present invention, the calling device is incorporated in the wristwatch. By adopting a conspicuous structure, the above-mentioned feeling of pressure is completely eliminated, and in addition, since the function can be sufficiently exerted with a simpler structure than a conventional wristwatch with a calling device, the size and weight of the wristwatch with a calling device are equal to those of the calling device. It can be kept slightly larger than a wristwatch without the device.
