Abstract

PURPOSE:To prevent a malfunction of a motor for an analog clock which is generating a sound, by synchronizing a driving signal of an analog device with a digital clock when a sound is being generated by a digital function. CONSTITUTION:By a digital clock system of a sound generation driving circuit 9, etc., a sound is generated from a sound generating device 10. On the other hand, when a sound is generated, a gate circuit 14 is opened by an output of a digital system time counter 8. Subsequently, a signal which sets an output of a digital system frequency-dividing circuit 7 to a clock, and synchronizes with a digital clock outputted by a synchronizing circuit 11 to which an output of an analog system frequency-dividing circuit 3 is provided is applied to an FF 4 forming a driving signal of an analog system motor 6. Accordingly, the motor 6 is driven, synchronizing with a minute period of a sound halt which gives no sense of incongruity to a viewer, such as a pause of a sound signal, a turning point of modulation frequency, etc., and a malfunction of an analog clock motor, caused by drop of supply voltage, etc. due to overlap of sound generation and motor driving is prevented.

Conventionally, in analog/digital composite electronic hour hands, the sound generation signal that drives the sound generation device has been synchronized with the digital clock, but not with the drive of the motor of the analog clock. Therefore, the batteries used in electronic clocks, which sometimes drive the motor and the sound generator at the same time, cause a voltage drop when a large current flows due to internal resistance. With electronic clocks, is there a risk that the motor may malfunction due to voltage drop when a sound is generated? Particularly in recent years, as wristwatches have become thinner and smaller, it is necessary to use thinner and smaller batteries with higher internal resistance, increasing the risk of the above-mentioned malfunctions.

In FIG. 1, it is a one-manufacturer oscillation circuit and outputs a signal that is a time standard. 2 is a frequency dividing circuit which divides the frequency of the signal of the oscillation circuit 1 (in this example, the frequency is divided up to 32H2 signal). 3 is a frequency dividing circuit for the analog hour hand, and in this example, it divides the frequency from 5 zHz to %.

P, FLO, and P, together with the gate 5, form a circuit that generates a drive signal for driving the motor. Reference numeral 6 is a motor which is operated by a motor drive signal and displays analog time. 7 is a frequency divider circuit for digital clocks s z
Divide down to Hz. A time counter 8 measures the time upon receiving the 1H1 signal and displays it digitally. Reference numeral 9 denotes a sound generator drive signal forming circuit, which receives the sound generation information given from the time counter group and modulates the sound generator at an appropriate frequency using the signals obtained from the frequency dividing circuits 2 and 7 or 8. In the conventional example, which generates a drive signal and drives 10 sound generators, the motor drive signal is formed only by an analog clock circuit, so the motor drive and sound generation are often asynchronous. There was a risk that both would be driven at the same time.

Both the motor drive signal and the I Hz multiplied signal of the digital clock are synchronized with the falling edge of 32 Hz, but due to time correction, etc., the two often become misaligned as shown in the figure. In the figure, the high-power acoustic signal indicates that the acoustic signal is output at Ht, and the shaded area indicates the period that overlaps with the motor drive. The present invention has been improved in consideration of this point.

In FIG. 2, numerals 1 to 10 are similar to the conventional example shown in FIG.

This is a synchronous circuit.

The black signal 12 gives the listener a sense of discomfort even if the sound is not output at about 20 times, such as at the end of the sound, at the change in the modulation frequency, or in areas with low sound pressure. The falling edge of the clock signal is synchronized so that it is not felt,
The frequency of the signal is at least twice the frequency of the signal input to the synchronization circuit 11DM, and the signal is irregular. 1
Reference numeral 3 is a signal indicating a sound generation period, and the logic level is "1" during this period and rOJ during other periods. 14 is a switch, a child circuit, and this circuit is a signal 13
As a switch signal, a signal synchronized with the digital clock is transmitted during the sound generation period, and the output of the analog clock frequency dividing circuit 5 is transmitted to the motor drive signal forming circuit composed of 4 and 5 during other periods. As a result, during the sound generation period, the drive of the motor can be synchronized with the metalwork 9 of the clock signal 12 described above, so that at least the part where the listener does not feel any discomfort due to the sound sensation is at least By using this in combination with a sound having a ringing pattern that does not generate sound output exceeding the pulse width, it is possible to avoid duplication of sound generation and motor drive without giving a sense of discomfort. . This situation is shown in a timing chart.

As described above, according to the present invention, it is possible to prevent malfunction of the motor by simply adding a circuit, without giving the listener a strange sensation of sound, and moreover, sound generation can always be performed by analog clocks or digital clocks. An analog/digital composite clock can be obtained that does not lose its function as a completely separate clock, even though it can output synchronized outputs to both. The present invention can be particularly effective in commercializing an analog/digital composite electronic timepiece with a sound generation function.
