Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic timepiece with a sound device, and more particularly to a display structure for a vibrating glass electronic timepiece that generates sound by fixing a piezoelectric element to the glass.

Generally, in electronic watches with acoustic devices that vibrate glass, piezoelectric elements are often simply fixed to the printed surface of the glass. Therefore, when combined with an electro-optical display element such as a liquid crystal, the module is flat and uninteresting in design, and furthermore, since the piezoelectric element is thick, it becomes necessary to provide a recess in the module to accommodate the piezoelectric element.

The present invention aims to eliminate the above-mentioned drawbacks and provide a display structure for an electronic timepiece with a sound device in which the display part is decorated with a partition plate that has a three-dimensional effect and is easy to see.

Embodiments of the present invention will be described below based on the drawings.
FIGS. 1 and 2 are longitudinal sectional views showing the main structure and plan views of the constituent parts.

In FIG. 1, the glass 1, the upper plate 4 and the lower plate 5 are arranged one on top of the other, the upper plate 4 and the lower plate 5 forming parting plates are held down by the lower end of the packing 7, and the glass 1 is placed in the case 8 by the packing 7. are hermetically fitted through the In Fig. 2A, there is no decorative pattern 3 on the lower surface of the glass 1, except for the transparent part 1a through which the displayed characters and figures can be seen through.
The piezoelectric element 2 is positioned and fixed at the corner 2a.

Further, an upper plate 4 is disposed at the lower part of the glass 1, and the piezoelectric element 2 is housed in the upper plate 4, and the displayed characters and figures of the electro-optical display device 6 are displayed through the transparent part 1a of the glass 1. It has an opening 4a that can be seen through.

Further, at the bottom of the upper plate 4, there is a small opening 5 through which the displayed character figure can be seen through the transparent part and the opening.
a is provided with a diameter smaller than that of the transparent portion 1a of the glass 1.

A display section of an electro-optical display device 6 is disposed below the lower plate and directly below the transparent section, opening, and small opening, and the transparent section, opening, and small opening are stepped and three-dimensional. It is structured as follows.

Also, a small hole 4 is provided at one end of the upper plate 4 and lower plate 5 of the parting board.
b, 5b are bored for one electrical connection terminal of the piezoelectric element 2, and furthermore, the lower plate 5 has a hole located directly below the piezoelectric element 2 provided on the glass 1 for the other electrical connection terminal. A second small hole 5c is provided to drive a buzzer in conjunction with an acoustic drive unit disposed within a timepiece device (not shown).

As described above, the present invention makes it possible to obtain a three-dimensional parting structure as the display structure of a glass vibrating electronic watch with an acoustic device, and also because the piezoelectric element can be housed with glass, an upper plate, and a lower plate, making it possible to create a module. There is also no need to provide a recess or the like for storage.
