Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an alarm sound generating device for a watch, and in particular, by generating a plurality of alarm sounds in a layered manner with staggered generation intervals, the present invention can more reliably remind the user of the set time. In addition to informing the user of the arrival of the alarm, it also generates a pleasant alarm sound that suits the user's preference.

Conventionally, various types of alarm sounds have been used as alarm sounds for watches, such as electronic sounds, bell-struck sounds, and melody sounds, but these alarm sounds have advantages and disadvantages for users. For example, electronic beeps, bell-thumpers, etc. are more effective at notifying the user that the set time has arrived than melody sounds, but they are difficult to hear and may be unpleasant for the user or people nearby. It often gives a feeling of pleasure. On the other hand, melody sounds are less likely to cause discomfort to users, but are inferior in their ability to notify users that the set time has arrived compared to bell-struck sounds and electronic sounds.

The present invention is intended to solve the above-mentioned problems of the conventional technology, and it is possible to more reliably notify the user that the set time has arrived, and to make the alarm sound constant from the time when the set time arrives. The occurrence intervals are sequentially shifted as time elapses, and the occurrences are repeated one after the other. and 1. - will notify the user when the set time has arrived with a relatively pleasant sound, and if the user does not notice, a new alarm sound will be emitted over and over again after a certain period of time to more reliably notify the user of the set time. can notify you that it has arrived. In addition, by sequentially overlapping alarm notification sounds every certain period of time, it is possible to provide alarm notification sounds that are unique and musically interesting.In particular, the alarm notification sounds that are generated sequentially from the set time can be combined with the same melody sound. By doing so, you can create the sound of a melody being sung in circles.

The present invention will be described in detail below based on the drawings.

FIG. 1 is a circuit diagram showing a first embodiment of the present invention.

In the first embodiment, a natural sound such as a bird's voice is generated as soon as a set time arrives, and then after a certain period of time the natural sound is layered to generate a melody sound, and after a certain period of time, the natural sound and melody sound are combined. It is characterized by the generation of electronic sounds overlapping each other.

In FIG. 1, a reference signal generator 2, a frequency dividing circuit 4, a waveform shaping circuit 6, a drive circuit 8, a motor 10, and a wheel train 12 constitute a normal analog display clock. This circuit is incorporated in the column 12 and outputs an H signal when a set time arrives. The notification start signal output circuit 16 outputs the frequency dividing circuit 4 from the arrival of the set time.
This circuit outputs a signal to output an alarm sound every predetermined period of time based on the output signal of the counter 18 that counts a predetermined periodic signal from the counter 18.

The first alarm circuit 20 outputs a signal for notifying natural sounds based on data output from a ROM 22 that stores data for creating natural sounds, an address counter 24 for reading data from the ROM 22, and R, 0M 22. It consists of a natural sound notification circuit 26. The present embodiment also includes a second alarm circuit 28 for generating a melody sound and a third alarm circuit 30 for generating an electronic sound. The second alarm circuit 28 includes a ROM 32 and a ROM 32 that store data for melody sounds.

Further, the third alarm circuit 30 includes a ROM 38 that stores data for generating and making an electronic sound, an address counter 40 for reading out the data in the ROM 38, and an electronic sound generating circuit for generating an electronic sound based on data for the electronic sound from the ROM 38. A mixer 44 consisting of a sound generation circuit 42 and a sound generation circuit 42 is a circuit that mixes notification signals from the natural sound generation circuit 26, the melody sound generation circuit 36, and the electronic sound generation circuit 42 and outputs the mixture to the notification circuit 46.

The operation of this circuit will be explained below.

When the set time arrives while the alarm set/non-set switch 48 is operated in the set state, the reference circuit 1 is activated.
The output signal of 4 becomes tr from I7.

This signal I] is input to the inverter 52 and one-shot circuit 54 of the notification start signal output circuit 16 via the AND gate 50. As a result, the output of the inverter 52 changes from H to L and is input to the reset input R of the flip-flop (hereinafter abbreviated as FF) 56, 58.
56, 58, and 60 are reset. After this, the positive single pulse generated in the one-shot circuit 54 becomes the FF
56 set human power S, FF5 via or gate 62
8.60, the output Q of FF56, the output Q of FF58, and the output enable 3 of FF60 become L, H, and H, respectively. Of these, the output Q of the FF 56 is the address counter 2 in the first alarm circuit 20.
Since the address counter 24 is connected to the reset input R of the frequency dividing circuit 4, the reset of the address counter 24 is canceled when the signal of the output Q becomes L, and counting ζ of the constant periodic signal from the frequency dividing circuit 4 is started. The address of the natural sound data stored in the ROM 22 is designated by the count value of the address counter 24, and the natural sound data is output. Based on this data, the natural sound generation circuit 26 outputs a signal for notifying natural sounds. This signal is input to a notification device 46 via a mixer 44 to generate natural sounds.

After a certain period of time has elapsed, the output signal of the counter 8 rises to H. This rising signal causes FF5

The melody sound data stored in the melody sound generation circuit 32 is read out, and the melody sound generation circuit 3
6 produces a melody sound signal. This melody sound signal is mixed with the natural sound signal from the first alarm circuit 20 by the mixer 44 and sent to the notification device 46. As a result, the notification device 46 generates natural sounds and melody sounds in a layered manner.

Furthermore, after a certain period of time has passed, the counter 18
The output signal of F' rises from L to I.
F56 output Q, FF58 output method.

All signals of the output Q of the FF60 become L. As a result, the reset of the address counter 40 of the third alarm circuit 30 is released, and counting of the constant cycle signal from the frequency dividing circuit 4 is started. The electronic sound data stored in the R,0M 38 is read out by the count output of the address counter 40, and the electronic sound generation circuit 42 outputs an electronic sound generation signal based on this electronic sound data. This electronic sound generation signal is mixed with the other natural sound signal from the first alarm circuit 20 and the melody sound signal from the second alarm circuit 28 by the mixer 44 and output to the notification device 46. As a result, the notification device 46 generates natural sounds, melody sounds, and electronic sounds in a layered manner.

FIG. 2 is an explanatory diagram showing the form of generation of the alarm sound in FIG. 1. As shown in the figure, a natural sound is generated when the set time (T) arrives, then a melody sound is generated superimposed on the natural sound after T1 time has elapsed, and an electronic sound is generated when T1 time has elapsed. According to this embodiment, the alarm sounds are generated one after the other every time a certain period of time has elapsed from the set time, so the user can hear it very easily and know more reliably that the set time has arrived. be able to. Furthermore, if the intervals at which natural sounds are generated, then melody sounds, and then electronic sounds are generated can be determined in advance. are given the same numbers and their explanations will be omitted. In the second embodiment, the first alarm circuit 64, the second alarm circuit 66, and the third alarm circuit 68 sequentially generate the same melody sound of a certain bar with the generation interval shifted, thereby making the melody round-singing. The ROM 70 in the first alarm circuit 64 is characterized in that it provides a pleasant alarm sound.
, the ROM 72 in the second alarm circuit 66, and the ROM 74 in the third alarm circuit 68 store the same melody sound data. The address counter 76 of the first alarm circuit 6'4 is a circuit that reads data stored in the ROM 70 based on the signal from the frequency dividing circuit 4, and similarly, the address counter 76 of the second alarm circuit 6' The address counter 80 of the third alarm circuit 68 is a circuit that reads data stored in the ROM 74. Furthermore, the melody sound generation circuit 82 in the first alarm circuit 64, the melody sound generation circuit 84 in the second alarm circuit 66, and the melody sound generation circuit 84 in the third alarm circuit 68 are generated.
The circuit 86 is a circuit that outputs a melody sound generation signal based on the melody sound output from the ROM 70, 72, and 74, respectively. Further, the detection circuit 8 of the first alarm circuit 64
8 detects the start time of the melody from the second alarm circuit 66 from the melody data stored in the ROM 70, and outputs the notification start signal output circuit 1 via the OR gate 90.
This circuit outputs a signal to 6. Second alarm circuit 66
The detection circuit 92 inside is also a circuit that detects the start time of the melody of the third alarm circuit 68 from the melody data stored in the ROM 72, and outputs a signal to the notification start signal output circuit 16 via the OR gate 84. . The detection circuit 94 in the third alarm circuit 68 is a circuit that detects the end of the melody based on the data stored in the R, 0M 74 and outputs it to the notification start signal output circuit 16 via the OR gate 96.

Therefore, when the set time arrives, the output Q+ of FF56 of the notification start signal output circuit 16, the output Q of FF58, and the output possible of F'F60 are L and H as before.

It becomes H. As a result, the address counter 76 is released from reset, starts counting the constant cycle signal from the frequency dividing circuit 4, and reads out the melody data stored in the ROM 70 based on the count output. Based on this melody sound data, the melody sound generation circuit 82 generates a melody sound signal, and the notification device 46 generates a melody sound. When this melody sound plays a specified number of bars, the detection circuit 88 detects it and outputs a pulse signal to the notification start signal output circuit 16 via the OR game 90. This allows output of FF56, output Q of FF58, etc.

The output σ8 signal of the FF 60 changes to L, L, and H, and in addition to the first alarm circuit 64, the second alarm circuit 66 operates as described above and outputs a melody signal. This melody notification signal is mixed with the melody sound signal from the first arm circuit 64 by the mixer 44,
The information is input to the notification device 46.

When the melody sound from the second alarm circuit 66 plays a certain number of bars, the detection circuit 9o detects it and outputs a pulse signal to the notification start signal output circuit 16 via the OR game 90. This allows the output of FF56 r t
Possible to output F F 5 g2. Output Q of F'F'60,
The signal changes to high, low, and low, and a melody sound signal is output from the third alarm circuit 68 in addition to the first alarm circuit 64 and the second alarm circuit 66. This melody sound signal is mixed with the melody sound signals from the first alarm circuit 64 and the second alarm circuit 66 by the mixer 44 and input to the notification device 46.

In this way, since the same melody sounds are generated one after another with a slightly delayed generation interval, the user hears the melody being played in a circular motion.

After this, the melody sound that is being generated ends in the order in which it was generated first, that is, the first alarm circuit 64, the second alarm circuit 66, and the third alarm circuit 68, but the melody is generated from the third alarm circuit 68. When the current melody ends, the detection circuit 94 detects this and outputs a pulse signal.

The pulse signal is input to one input of the AND gate 96, and the output of the AND gate 96 becomes L only while the pulse signal rises to I]. At this time, the output signal of the inverter 52 becomes H and resets the FFs 56, 58, and 60.
The outputs Q, , Q, , u, become H.

As a result, all the count values of address counters 76, 78, and 80 are cleared, and the state returns to the initial state. When the pulse signal from the detection circuit 94 falls from I( to L), the output signal of the AND gate 96 rises from L to H. As a result, the output signal of the AND gate 52 changes from H to L. After canceling the reset of F F, 56° 58.60, the pulse signal generated from the one-shot circuit 54 causes the signal beams of the outputs Q, , Q, , Q, to become H,
Then, the address counter 76 starts counting, reads out the stored contents of the ROM 70, and generates the melody round sound again.

FIG. 4 is an explanatory diagram showing the form of the alarm sound in the second embodiment. In the figure, A is the first alarm circuit 64
B is the melody generated from the second alarm circuit 6.
C is the melody generated from the third alarm circuit 68. As shown in Figure 0, when the melody generated from the first alarm circuit 64 is played for four bars, the second alarm circuit 66 When the same melody is generated from the second alarm circuit 6675; and the melody generated from the second alarm circuit 6675 is played for four bars, the same melody is generated from the third alarm circuit 68. If the same melody data is stored in each ROM so that the same melody data can be stored in each ROM, it will be possible to generate a ringing sound of the melody as an alarm sound at the time of setting. It is possible to provide a musically interesting alarm notification sound.

Said 1st. In the second embodiment, the alarm sound is 3
Although one notification sound is overlapped, it is also possible to sequentially overlap more notification sounds.

Further, in the first embodiment, natural sounds, melody sounds, and electronic sounds are sequentially superimposed, but it is also possible to use other notification sounds.

As described above, according to the present invention, by sequentially stacking a plurality of alarm sounds at predetermined time intervals after the arrival of the set time, it is possible to more reliably notify that the set time has arrived. It is possible to provide an alarm sound generation device for a watch that can notify the user and generate an alarm sound that is pleasant to the ears.
