Description

Description: TECHNICAL FIELD The present invention relates to an electronic wristwatch provided with a sound generating device and an electro-optical data display device for displaying data.

[Prior art and its problems]

Recently, many functions have been added to electronic watches. For example, as in USP4769836, a large number of telephone numbers are stored in a memory in advance, read and displayed arbitrarily by a switch operation, and a dial tone corresponding to the telephone number is generated to automatically make a telephone call. There is an electronic watch with a dialer function. In addition, there is a voice alarm wristwatch that outputs the current time by voice when a switch is operated, as in USP3998045.

Such a wristwatch requires an electro-optical data display device, a large sounding device capable of generating large and clear sounds, and a large number of switches for inputting telephone numbers or messages. There is a disadvantage that it becomes.

As a structure for miniaturizing a wristwatch, for example,
In the electronic wristwatch with a computer disclosed in Japanese Patent No. 993, the watch case is divided into a lower case and an upper case, and the upper case is attached to one end of the lower case so as to be freely opened and closed. A time display liquid crystal display is provided on the upper surface of the upper case, and a computer liquid crystal display is provided on the lower surface. A key switch is provided on the upper surface of the lower case, a circuit board and a battery are arranged inside, and the lower surface of the case is closed with a back cover.

In such an electronic wristwatch, the planar shape can be reduced, but the key switch is provided on the upper surface of the lower case having a space for accommodating electronic components therein. The upper plate or lower plate of the case when the key switch is pressed down strongly because the lower plate on the switch side and the upper plate on the switch surface side are stacked, and the electronic switch is housed inside. The upper plate and the lower plate must be made thicker, and the lower case becomes thicker, and thus the entire watch becomes thicker.

In a wristwatch with a computer shown in USP4108340, a watch case containing an analog watch and a computer case containing a computer device are fixed back to back, and a band is provided in a through hole provided between these cases. , And the two cases can be inverted as necessary to be used with the analog clock or the calculator up.

In this timepiece, the planar shape of the two cases can be reduced, but there is a space inside the case where electronic components are stored.
Because the two cases overlap, the whole becomes thicker.

In the wristwatch shown in USP4444513,
The watch case is composed of an upper hearth case and a lower half case, and an analog display section is provided on the upper half case,
It has been considered that an electro-optical data display device and a switch are provided side by side on a lower half case, and the upper half case is connected to the lower half case so as to be freely opened and closed. However, also in this wristwatch, since the upper half case and the lower half case each having a space for accommodating electronic components therein overlap, the thickness of the entire timepiece increases.

Although the wristwatches of the above three publications do not incorporate a sound generator, an electronic wristwatch with a dialer function or a voice alert wristwatch must output a clear sound. Must be thicker.

[Object of the invention]

The present invention has been made in view of the above-described circumstances, and an object of the present invention is to make a display unit of an electro-optical data display device large while making the entire watch case thin and small, and to use a large number of switches.
