電スピーカを駆動する方法が既に知られ実施されている
。Conventionally, in electronic watches and the like that have a means for generating alarm sounds such as time signals and alarm clocks, a method of driving an electromagnetic or piezoelectric speaker with a square wave of a specific frequency is already known as a means for generating the alarm sound. It has been implemented.
しかしその方法は単一、もしく＃″ｉ２種類程度の固定

ーカ駆動用に広範囲な周波数を得ることを目的とする。The present invention eliminates this drawback, and includes a dedicated multi-stage frequency division stage for obtaining the speaker drive frequency, a ROM that stores information for controlling the frequency division ratio of the frequency division stage, and a ROM that stores information for controlling the frequency division ratio of the frequency division stage. It has a binary counter to drive the ROM,
With control information pre-programmed in ROM,
The purpose is to obtain a wide range of frequencies for speaker drive by changing the frequency division ratio of the frequency division stage for speaker drive frequency setting.
以下本発明を添付図面に基づき詳細に説明する。Hereinafter, the present invention will be explained in detail based on the accompanying drawings.

。Suppose that it is raining at B and C. The frequency division ratio information is written to the frequency division ratio fu control ROM 3, and when the alarm is selected, the ROM drive binary counter 4 starts operating, and the frequency division ratio is controlled by the address line AQ-A77).

When the speaker drive frequency setting variable frequency division stage output matches the frequency division ratio A, the speaker drive frequency setting variable frequency division stage 1 is reset and as a result operates as an A-adic counter.

う効果を有する。As described above, in the present invention, there is a frequency divider of several stages capable of variable frequency division for generating an alarm sound. Since it is possible to obtain an alarm speaker drive frequency that changes over time, it is possible to generate an audibly interesting alarm sound, and by refolding the contents of the ROM, it is possible to easily generate an alarm sound. It has the effect of being able to change the sound.
