Description

[Detailed description of the invention]

(Field of Industrial Application) The present invention relates to an improvement of a watch with a snooze function, and in particular, it is possible to switch between a watch with and without a snooze pause operation confirmation sound generation function using a single integrated circuit. Concerning what was done. (Prior Art) Conventionally, clocks have been devised that generate a confirmation sound each time a snooze switch is operated, such as a clock disclosed in Japanese Utility Model Publication No. 61-11670. By generating the confirmation sound in this manner, it becomes possible to easily confirm whether or not the switch has been operated. (Problem to be solved by the invention) When the notification sound is a simple electronic sound as in the conventional case, it is necessary to design an IC to uniformly generate a confirmation sound and adapt it to multiple types of watches. However, depending on the content of the sound, it may be better not to add a pause operation confirmation sound, or if there is no confirmation sound, in the watches that have been commercialized in recent years that notify by sound. However, there were various types of ICs that could clearly indicate that a switch had been operated, and a new IC had to be redesigned each time, resulting in higher costs. The purpose of the present invention is to make it possible to easily switch between a device with a function of generating a snooze pause confirmation sound and a device without it, and to standardize the IC.
The aim is to reduce costs. (Means for Solving the Problems) The audio clock with snooze of the present invention includes a clock section, a guide switch that outputs an alarm-on signal, a ring stop switch, and a ring-stop switch that allows the alarm-on signal to pass when the alarm is not turned off. a first gate, an operation signal generation circuit that outputs an operation signal in response to an alarm-on signal, a snooze switch, and a snooze start signal that outputs first and second snooze start signals in response to an on operation of the snooze switch. a snooze counter that counts in response to the first snooze start signal and outputs a count-up signal;
a snooze mode signal generating circuit that outputs a snooze mode signal that prevents the generation of an operating signal from the time the snooze signal is generated to the time that the count up signal is generated, and a start circuit that outputs a start signal in response to the generation of the alarm on signal and the count up signal. A signal generation circuit, an audio selection counter for counting count-up signals, and outputting an audio signal corresponding to the count value of the audio selection counter in response to generation of a start signal, and operates when a snooze start signal is generated and when the operation signal disappears. An audio clock with a snooze function, which includes an audio circuit that stops the first snooze start signal, and a notification circuit that inputs an audio signal to notify the audio, the mode switching circuit outputs a switching mode signal, and the audio selection counter outputs the first snooze start signal. a first snooze operation start detection circuit that outputs a step signal as a step signal; and a second snooze operation start that outputs a start signal from a start signal generation circuit in response to generation of a second snooze start signal when a switching mode signal is generated. It consists of a detection circuit, and an interlace selection circuit that supplies a second snooze start signal as an increment signal to the audio selection counter in place of the count-up signal when the switching mode signal is not generated. (Function) In the audio clock with snooze configured as described above, if the switching mode signal is not output from the switching mode circuit, the start signal generation circuit is activated when the alarm is turned on or when the count-up signal from the snooze counter is generated. only generates a start signal. At this time, the audio selection counter also outputs an increment signal output from the first snooze operation start detection circuit in response to the first snooze start signal, and an output from the jump selection circuit when the second snooze start signal is generated. advances its count in response to an increment signal. That is, when the switching mode signal is not generated, the sound is generated only when the alarm is on or when the snooze pause ends, and the switching of the sound is advanced by two when the snooze switch is operated, and as a result, the sound is heard as the snooze pause confirmation sound. The audio will be skipped and not output. On the other hand, when the switching mode signal is output from the switching mode circuit, the start signal generating circuit is not limited to the case described above. The start signal is also output in response to the signal. Additionally, the audio selection counter advances its count only in response to the first snooze start signal. As a result, when the switching mode signal is generated, a sound is generated not only when the alarm is on and when the snooze pause ends, but also when the snooze switch is operated.The switching of the sound is advanced by 1 for each snooze switch operation, and the snooze pause operation is confirmed. Sound is output. The sound notified by the above operation is as shown in the table, for example.
