When installing a movement offset from the case, the structure is limited using conventional technology, such as the structure of the back cover to increase sound pressure, the structure of the back cover to improve waterproof performance, and the design of the movement that affects its appearance. The location of etc. will be regulated. Also, for high-pressure waterproof cases, with the screw back cover structure, which is very good for waterproofness and sound pressure, if the piezoelectric element is offset from the center of the back cover as described above, where will the back cover stop when rotating? There is a risk that the movement will shoot out if you do not understand. On the other hand, in order to solve the drawbacks of the conventional ones, this invention has a structure that is affected by the screw back cover structure used in high-pressure waterproof cases and the size of the piezoelectric element. The purpose is to conduct electricity from the piezoelectric element and to prevent the terminals of the movement from touching the piezoelectric element.

In order to solve the above problems, this invention takes electricity from the movement coil to the piezoelectric element,
Insert an auxiliary terminal spring in the form of an extension of the movement's terminal and measure the electrical connection to the back cover. If the alarm coil does not reach the piezoelectric element, a conductive pin is inserted in the middle and an insulating bushing made of plastic or the like is inserted between the conductive pin and the auxiliary terminal spring.

This invention will be explained below based on the drawings.
In FIG. 1, reference numeral 1 denotes a piezoelectric element, which is bonded to the inner surface of a screw-type back cover 8 with an adhesive or the like. 2 is an alarm coil, which is elastically installed between the movement and the transmission pin 6. 3 is a terminal, which is provided in the movement and has an auxiliary terminal spring 5.
is connected to the top of the 4 is a middle frame, which is provided inside the body of the wristwatch case and holds the movement. The auxiliary terminal spring 5 is prevented from rotating by the rotation stopper.
It is positioned on the middle frame 4, and the lower part is provided to engage with the back cover 8, and the engaging part with the back cover 8 has a convex part that is higher than the thickness of the piezoelectric element 1. It is provided across the element 1. For this,
The piezoelectric element 1 can be provided larger inside the convex portion of the auxiliary terminal spring 5. In the auxiliary terminal spring 5, an insulator (button) 7 for holding the transmission pin 6 is press-fitted into a stepped hole. This insulator (bush) 7 has a gap (backlash) in the thickness direction with respect to the transmission pin 6 and the auxiliary terminal spring fitted into the hole of the insulator (bush) 7.

As explained above, this device has a simple structure in which the terminal is extended by an auxiliary terminal spring to prevent shortening due to contact between the terminal and the piezoelectric element, and is excellent in design-oriented movement placement and diversification of structure. Especially when installing the movement in a case offset from the center of the case, accurate conduction can be achieved even with a screw-backed structure. Furthermore, since the terminal spring can be made thinner, it is possible to prevent the thickness of the watch from increasing.
