Abstract

PURPOSE:To eliminate or reduce an evil caused by an artificial sound by providing a generating means for an alarm tone containing two pure sounds that are not in mutually in harmonic relation. CONSTITUTION:Reference signal generators 1 - 3 generate signals of frequencies not in mutually harmonic relation, higher harmonic signal generating circuits 4 - 6 generate higher harmonics of the frequency of a reference signal, and a signal processor and synthesizer 7 combine plural signals at a proper rate to perform conversion into an alarm tone. This alarm tone includes three pure sounds which are not in mutually harmonic relation and their higher harmonics, i.e. seven frequency components in total. Consequently, unnaturalness caused by an artificial sound is eliminated or reduced.

Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to a sounding means used in wristwatches and the like.

[Prior Art] Some conventional sound generation means include means for generating an alarm sound used for alarm alarms, time signals, schedule management, and the like.

[Problems to be Solved by the Invention] However, the alarm sound generated by the conventional sounding means was a "beep" sound. As a result, the following issues arose.

(1) The "beep" sound itself was very artificial, unnatural, and not pleasant to hear.

(2) Similarly, since the "beep" sound itself is very artificial, the alarm sound stands out from the surrounding environmental sounds and is likely to be a nuisance to others.

(3) For this reason, for example, in a classical concert hall, when an alarm sound is heard, the tension between the performer and the audience is broken, and a good performance is hindered.

(4) Also, since most watches make the same beeping sound, it was difficult for me to distinguish between my own alarm sound and the alarm sound of others.

Therefore, an object of the present invention has been made to solve the above-mentioned problems.

[Means for Solving the Problems] The sound generation means of the present invention is characterized in that: (1) the alarm sound generation means includes at least two pure tones having no overtone relationship with each other as sound components; It is also characterized in that (2) it includes means for generating an alarm sound having a spectrum of 1/f fluctuation. It is also characterized in that (3) it is equipped with means for generating an alarm sound that imitates the sounds of nature. It is also characterized in that (4) it is equipped with means for generating an alarm sound that imitates sounds from the environment. It is also characterized in that (5) it is equipped with means for generating an alarm sound that imitates a human voice.

[Function] The sound generation means configured as described above is equipped with an alarm sound generation means that includes at least two pure tones that have no overtone relationship with each other as sound components, so that the sound generation means configured as described above is able to suppress the alarm generated by the conventional sound generation means. It is possible to generate alarm sounds with various tones with good characteristics, rather than artificial and unnatural sounds.

Therefore, various harmful effects caused by artificial sounds can be eliminated or reduced.

[Examples] Hereinafter, the present invention will be explained in detail based on Examples. However, the present invention is not limited to the following examples.

(Embodiment 1) FIG. 1 is a flowchart regarding an alarm sound generating means in a wristwatch according to Embodiment 1 of the present invention. 1.2
．． 3 is a reference signal generator (reference signal generator 1, reference signal generator 2, reference signal generator 3), each of which has a function of generating signals of frequencies that are not harmonics of each other. Further, the waveform of the reference signal can be arbitrarily selected from various waveforms including a sine wave, a rectangular wave, and a triangular wave.

4.5.6 is a harmonic signal generator (harmonic signal generator 1,
a harmonic signal generator 2, a harmonic signal generator 3),
Each has a function of generating harmonics of the frequency of the reference signal. Further, these harmonic signal generators are capable of combining the generated harmonics or the original reference signal at an arbitrary intensity ratio. Reference numeral 7 denotes a signal processing synthesizer, which has a function of combining and synthesizing a plurality of signals generated by the above-mentioned harmonic signal generator at an appropriate ratio. Reference numeral 8 denotes an amplifier, which has a function of amplifying the weak signal generated by the signal processing/synthesizing device 7. 9
is a speaker and has a function of converting the electrical signal amplified by 8 into an alarm sound. Reference numeral 10 denotes a control section, which has a function of controlling the functions of the harmonic signal generator and the signal processing/synthesizing device (for example, control for giving a ratio when combining signals at an appropriate ratio). In this embodiment, the control procedures of the 10 control units are fixed and stored in ROM. (Of course, the control procedure may be arbitrarily selected so that the user of the wristwatch can select various alarm sounds.) Next, the spectrum of the alarm sound in the wristwatch of this embodiment is Shown in Figure 2. As can be seen from FIG. 2, this alarm sound includes a total of seven frequency components, including three pure tones and their harmonics that have no overtone relationship with each other.

When I listened to the alarm sound generated by the wristwatch of this example, I found that it was not an artificial sound like the alarm sound generated by conventional wristwatches. It was also possible to eliminate or reduce the unnaturalness caused by artificial sounds.

Furthermore, by arbitrarily selecting the frequency components that make up the alarm sound, we were able to generate alarm sounds with various tones with good characteristics.

(Example 2) In addition to the three reference signal generators and harmonic signal generators of Example 1, a white noise generator and a bandpass filter were placed before the signal processing synthesizer.

When I listened to the alarm sound generated by the wristwatch of this example, I found that it was not an artificial sound like the alarm sound generated by conventional wristwatches. It was also possible to eliminate or reduce the unnaturalness caused by artificial sounds.

In addition, by arbitrarily selecting the frequency components that make up the alarm sound, and by adding a signal consisting only of a white noise band, it is possible to create a tone with many different good characteristics than in the first embodiment. I was able to generate an alarm sound.

(Example 3) In Examples 1 and 2, an example was shown in which the alarm sound includes three pure tones that have no overtone relationship with each other as components of the original sound. 20 unrelated pure tones were included as sound components. Furthermore, the signal processing synthesizer can not only simply synthesize input signals, but also perform various calculations such as adding and subtracting frequencies.

When I listened to the alarm sound generated by the wristwatch of this example, I found that it was not an artificial sound like the alarm sound generated by conventional wristwatches. It was also possible to eliminate or reduce the unnaturalness caused by artificial sounds.

In addition, by appropriately selecting the frequency and strength of the 20 signals, an alarm sound with a tone and sound that the owner prefers, which has many more good features than in the first and second embodiments, can be created. could occur. As a result, the owner could choose a pleasant alarm sound, and at the same time could instantly distinguish between his own alarm sound and that of others.

(Example 4) Although the watch has a configuration similar to that of Example 3, the frequency and intensity of multiple signals are selected to create a watch with a spectrum as shown in Figure 4, for example, so that it sounds like a wave. Now generates an alarm sound.

Figure 3 shows the spectrum of the alarm sound of this wristwatch.

When I listened to the alarm sound generated by the wristwatch of this example, it was not an artificial sound like the alarm sound of a conventional wristwatch, but it was a pleasant sound that made me feel at peace.

Also, this alarm sound is not an artificial sound, but a very natural sound, so even if it is someone else's alarm sound, it will not bother you much, and even if it starts going off in the middle of a concert, it will not bother you much. This made it less likely to interfere with a good performance.

(Example 5) Although the wristwatch has a similar configuration to Example 3, 'Fi
! The frequency and intensity of the H signal were selected to generate alarm sounds that imitated sounds such as ``wind,''``rain,''``murmur,'' ``bird chirping,'' and ``the sound of insects.''

When I listened to the alarm sound generated by the wristwatch of this example, as in the case of Example 4, it was not an artificial sound like the alarm sound of a conventional wristwatch, but a pleasant feeling that made me feel at peace. .

Also, this alarm sound is not an artificial sound, but a very natural sound, so even if it is someone else's alarm sound, it will not bother you much, and even if it starts going off in the middle of a concert, it will not bother you much. This made it less likely to interfere with a good performance.

(Example 6) Although the watch has a similar configuration to Example 3, the frequencies and intensities of multiple signals are selected, such as "violin",
Alarm sounds that imitate sounds such as ``piano'', ``clarinet'', and ``the sound of walking on grass'' are now generated.

When I listened to the alarm sound generated by the wristwatch of this example, I found that, as in Examples 4 and 5, it was not an artificial sound like the alarm sound of a conventional wristwatch, but a sound that made me feel at peace. It felt comfortable.

Also, this alarm sound is not an artificial sound, so even if it is someone else's alarm sound, it will not bother you much, and even if it starts going off in the middle of a concert, it will not bother you too much. It was unlikely to get in the way of a good performance.

(Example 7) Although the watch has a similar configuration to Example 3, the frequency and intensity of multiple signals are selected to imitate sounds such as "human voices,""babycries," and "human snores." now generates an alarm sound.

When I listened to the alarm sound generated by the wristwatch of this example, I found that, as in Examples 3, 4, and 5, it was not an artificial sound like the alarm sound of a conventional wristwatch, but a soothing sound. It felt like I was remembering something.

In addition, this alarm sound has a stronger effect of attracting attention than the alarm sound of a conventional wristwatch, so it is possible to increase the effect of the alarm with a sound that is lower than the alarm sound of a conventional wristwatch, reducing alarm noise. We were able to reduce power consumption.

Although this embodiment has been explained using a wristwatch, such a sounding means can also be used for other products.

[Effects of the Invention] The generated alarm sound is not an artificial and unnatural sound like the alarm sound of a conventional wristwatch, and has the effect that it is not unpleasant to listen to.

Further, the wristwatch of the present invention includes means for generating an alarm sound having a 1/f fluctuation having a spectrum of 1/f fluctuation;
Since it is characterized by having a means for generating an alarm sound that imitates the sounds of the natural world or a means for generating an alarm sound that imitates sounds from the environment, the generated alarm sound is similar to the alarm sound of a conventional wristwatch. It is not an artificial sound, but has the effect of creating a pleasant feeling that makes you feel at peace. Moreover, this alarm sound is not an artificial sound, so even if it is someone else's alarm sound, it will not bother you much, and even if it starts going off in the middle of the concert, it will not bother you so much, so it will help you play well. It also has the effect of being less likely to interfere with

Further, since the wristwatch of the present invention is characterized by being equipped with a means for generating an alarm sound that imitates a human voice, it is possible to increase the effect of the alarm with a sound that is smaller than the alarm sound of a conventional wristwatch. Since it is equipped with a means for generating a low-noise humming sound, it is possible to increase the effect of the alarm with a sound that is smaller than the alarm sound of conventional sounding means, which reduces alarm noise and reduces power consumption. The effect is that it can be reduced.
