DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable timepiece with an electronic device, and more particularly to a portable timepiece structure suitable for attaching a sounding device such as a buzzer to the portable timepiece.

[0002]

2. Description of the Related Art A variety of portable buzzer-equipped watches with a built-in buzzer in portable watches such as wristwatches and pocket watches have been developed. For example, as an electronic buzzer with a built-in electronic buzzer inside a wristwatch, a piezoelectric element placed on the inner surface of the back cover via a heat-sensitive adhesive and bonded by heating is electrically connected to the watch movement. Something is connected. Such a wristwatch with an electronic buzzer is designed to alert the wearer by the sound of the electronic buzzer.

[0003]

However, the electronic buzzer using the piezoelectric element is sealed in a watch case.
Since the sound is designed to be heard only by the wearer, the sound generated is relatively small, and is not sufficient, for example, as an alarm sound for notifying a person around the wearer that danger is imminent. There is a problem. To generate an audible alarm, it is necessary to incorporate a buzzer with a large volume, which inevitably increases the power consumption of the buzzer. In other words, there is a problem that the back of the watch case must be opened every time the battery is replaced.

[0004] Further, when an abnormality or failure occurs in the piezoelectric element constituting the electronic buzzer, the back cover of the watch case must be replaced, so that the production efficiency in the production process is reduced and the product is completed even after completion. There is a problem in that maintenance is troublesome and costly.

Further, in order to increase the noise generated by the buzzer, it is necessary to increase the size of the buzzer itself, and also to increase the size of a built-in battery, a solar battery, and a power generation mechanism in order to increase the battery capacity. It is necessary to make the watch case itself larger than usual, and there is a problem that a case of a normal size watch cannot be used.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to improve the workability or manufacturing efficiency of battery replacement and maintenance in a portable timepiece having a structure to which an electronic device is added.
