Abstract

PROBLEM TO BE SOLVED: To improve convenience of a musical sound generator with a clock function. SOLUTION: When a melody is selected by a dip switch 19b in a mode except a sound-attenuation mode, the melody, etc., are played for demonstration, therefore, it is possible to understand what the selected melody and natural sound are without waiting for the timing of the play. In a three-minute intermittent sound-generation mode, a play for wakening is performed at the time of starting driving in the morning, and a play for sleeping is performed in the evening. A user has only to set the generator to the three-minute intermittent sound- generation mode, and the user does not need to set the generator to the modes for wakening and sleeping performances. Since it is unnecessary for the user to operate various settings, ease of operation is improved. Moreover, it is also possible to simplify the configuration of an operation part for setting, for example, since a melody name display part is not necessary, nor a special mode is required, any operation part and the expansion of display control software is not necessary, and both the hard- and software are not complicated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a tone generator.

[0002]

2. Description of the Related Art There is a tone generator which has a clock function (timer function) and generates a tone when a set time, month, day, day of the week, season or the like is reached. A well-known example is an electronic alarm. There are electronic music box clocks incorporated in monuments such as clocks and parks.

In such a tone generator with a clock function, the tone color and the sequence (such as the tone corresponding to the parameter) accessed using the operation timing setting data as a parameter are uniquely defined by the specifications set by the design manufacturer. And there were not many parameters that could be set on the user side. That is, the specifications were fixed.

[0004] In some cases, a considerable number of parameters are released to the user so that the user can set the reproduction start time and end time of the musical tone, the number of music to be reproduced, the volume, etc.
No. 62695).

[0005]

However, Japanese Patent Application Laid-Open No.
In the technique disclosed in Japanese Patent Application Laid-Open No. 162695, the operation is complicated because the setting items are diversified, and the display unit 5 is indispensable for the operation unit 7 as shown in FIG.

In the apparatus disclosed in Japanese Patent Application Laid-Open No. 3-162395, a song to be played back at a set playback start time (for example, 6 am) can be selected from a song list displayed on a display unit. I didn't know how the song would be played until that time (6 am).

This problem can be solved by, for example, displaying a selection candidate song name on the display unit and providing a mode in which the music is played for a short time for a trial listening. ) And additional display control software, which complicates both hardware and software.

Further, when the performance interval is designated, the performance is always performed at the same interval, and for example, it is not possible to make flexible settings on the assumption that the user wakes up in the morning or sleeps at night. In other words, the conventional tone generator with a clock function has problems such as fixed specifications and complicated operation even if various parameters can be set by the user, and is not convenient to use.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the usability of a musical sound generator with a clock function.

[0010]

Means for Solving the Problems and Effects of the Invention A musical sound generating apparatus according to a first aspect of the present invention for solving the above-mentioned problems includes, as illustrated in FIG. Or a clock means for calculating any of the days of the week,
Timing setting means for setting a timing for performing the performance (performance timing); timing determining means for determining whether or not the performance timing is reached by referring to a calculation result of the clock means; A musical tone generating device comprising: a musical performance control means for causing the musical performance means to execute a musical performance when it is determined that the timing is a timing. A musical performance control means for controlling a performance mode of the musical performance means in accordance with the set musical performance timing It is characterized by having.

In this musical sound generating apparatus, the user sets the performance timing by the timing setting means. The timing judging means judges whether or not it is the performance timing by referring to the calculation result of the clock means, and the performance control means causes the playing means to execute the performance when the timing judging means judges that it is the performance timing. . At this time, the performance mode control means controls the performance mode of the performance means in accordance with the performance timing set by the timing setting means.

The performance timing may be set, for example, at a specific time or date and time, or at intervals of one hour or two hours, and also includes setting of continuous performance. Alternatively, it is also possible to make settings based on conditions other than time, such as when there is an event (for example, when starting up or when the mode changes). Each setting can be set.

The performance mode includes the setting of a music piece, the musical instrument or the composition of the music piece, the tempo,
Some or all of the elements that can be changed when performing a performance, such as volume, fade-in / out, number of repetitions, and intervals. Here, a song is taken as an example, but a sound (natural sound) derived from nature such as a sound of a bird other than a song or a water sound of a river or the like may be used. In addition, an actual performance or a natural sound recorded or converted into data may be used as the sound source data or a synthesized sound. In short, the performance of the present invention is to generate some kind of sound, and the form is how to make the sound.

The performance mode control means determines or selects a performance mode in accordance with the set performance timing, and controls the performance mode. Therefore, although there is no particular limitation on the performance means, an electronic signal for generating a sound signal based on digital sampling data and operating a speaker with the sound signal is considered in consideration of various performance modes. A simple playing means is preferred.

The user does not need to set the performance mode only by setting the performance timing by the timing setting means, so that various operations are unnecessary.
Usability is improved. In addition, the configuration of the operation unit for setting can be simplified.For example, since a song name display unit is not required and a special mode is not required, no additional controls and display control software are required, and hardware and software are not required. Does not complicate.

As shown in FIG. 5, the musical tone generating apparatus according to the second aspect has a playing means for playing a musical tone, a clock means for calculating time, month, day or day of the week, and a timing for executing the performance. Timing setting means for setting (performance timing); content setting means for setting the content of the performance by the performance means; and timing determination for determining whether or not the timing is the performance timing by referring to a calculation result of the clock means. Means for playing the content set by the content setting means when the timing determination means determines that the timing is the performance timing, the performance control means causing the performance means to execute the content set by the content setting means. When the content of the performance is set by the means, it is determined that the performance timing has not been determined by the timing determination means. Also characterized by comprising a demonstration performance control means for executing a demonstration performance of what is the set to the playing means.

In this tone generating apparatus, the user sets the performance timing by the timing setting means. In a normal driving state, the timing determining means determines whether or not it is the performance timing by referring to the calculation result of the clock means,
The performance control means causes the performance means to execute the performance when the timing determination means determines that it is the performance timing.

On the other hand, when the user sets the content to be played by the content setting means, the demonstration performance control means causes the performance means to execute the demonstration performance of the set content irrespective of the judgment by the timing judgment means. To set the content to be played means to set the type of a song or the above-mentioned natural sound. When the setting operation is performed, a demonstration performance of the set content is performed. You can listen to what songs are played and how.

Therefore, it is possible to confirm how the music is performed without waiting until the set performance timing (for example, performance start time), and the usability is improved. In addition, the configuration of the operation unit for setting can be simplified.For example, since a song name display unit is not required and a special mode is not required, no additional controls and display control software are required, and hardware and software are not required. Does not complicate.

The demonstration performance may be performed, for example, for one entire song, but it takes a relatively long time, and there is no need to perform that much as a trial listening. Therefore, the demonstration performance is preferably shorter than the performance (normal performance) executed at the performance timing. Also, since it is only necessary that only the set person can listen to the test, the volume should be lower than in the normal performance.

In particular, if there is a setting to stop (do not execute) the performance depending on the time zone (for example, at midnight), a demonstration is performed if the setting of the content to be played is a time zone in which the performance is not executed. It is preferable to provide performance prohibition means for prohibiting performance. Thereby, it is possible to prevent the performance from being performed unexpectedly at midnight, for example, and disturbing the surroundings.

According to a third aspect of the present invention, there is provided a musical sound generator.
In the musical sound generating device described above, the performance mode control means according to the first aspect is provided, so that the effects of the configurations according to the first and second aspects can be exerted, and the device is more convenient to use.

Further, the sound source board 14 is provided with a timer 35 corresponding to clock means. The timer 35 has a calendar function and can measure the year, month, day, day of the week, and time. Timer 35
Is connected to the CPU 20, and the CPU 20
5 data can be obtained. Further, the CPU 20 obtains time information from the cleaner board 13 and corrects the time and the like of the timer 35 in accordance with a timer (not shown) of the cleaner board 13 (the timer 35 is made dependent on the timer of the cleaner board 13). Basically, both timers indicate the same time.

A group of dip switches 19, which are set and operated by the user with respect to the performance by the sound source board 14, are composed of two sets of dip switches 19a and 19b as shown in FIG. The upper two bits (sw1, sw2) of the left dip switch 19a are used for sound generation setting. As shown in FIG. 3B, the sound generation mode includes a mute mode, a three-minute no-sound mode, a 30-minute once sound mode, and a continuous sound mode. Either can be set. The dip switch 19a (especially the upper two bits) corresponds to the timing setting means.

The mute mode is a mode in which background music (BGM) is not performed, and no sound is produced except for a warning sound such as a malfunction of the air cleaner 10, and the three-minute missing sound mode is in the morning (5:00 to 11:00). ) And night (1)
The mode in which the BGM is performed for three minutes every two hours at the start of driving from 8:00 to 5:00) and the once-in-one-sounding mode are performed in the morning (5:00 to 11:00) and at night (18:18). 00 ~
The mode in which the BGM is played for only 30 minutes from the start of driving at 5:00), and the continuous sounding mode is in the morning (5:00 to 11:
00) and during the night (18:00 to 5:00), the BGM is played continuously.

The lower 2 bits (sw3, sw4) of the dip switch 19a are used to select a natural sound or a piano tune. When sw3 is turned on or off, whether the morning BGM is a piano tune or a natural sound is determined. Can be set (Fig. 3 (c)), sw4
By turning on / off, it is possible to set whether the night BGM is a piano music or a natural sound (FIG. 3D).

The upper two bits (sw1, sw2) of the right dip switch 19b are used for selecting the BGM in the morning.
Sw3 of dip switch 19a (natural sound, piano music)
According to the correspondence, the setting as shown in FIG. Specifically, if sw3 of the dip switch 19a selects natural sound, automatic selection of natural sound, morning bird, morning cuckoo, and night sea can be set. In automatic selection, morning bird and morning cuckoo can be set. Perform every other day. If sw3 of the dip switch 19a selects a piano song,
Automatic selection of piano music, maiden's prayer, fantasy improvisation, splendid waltz can be set.In the case of automatic selection, maiden's prayer, fantasy improvisation, splendid waltz, lady riding, spinning song, waltz of a dog, and Turkey March songs are selected and played in order. Switching of songs during automatic song selection is performed for each performance.

The lower 2 bits (sw3, sw4) of the DIP switch 19b on the right side are used for selecting BGM at night.
As in the case of the morning, setting as shown in FIG. 3F is possible by correspondence with sw4 (natural sound, piano music) of the dip switch 19a. Dip switch 19a
If w4 selects natural sound, automatic selection of natural sound, night owl, night insect, and night sea can be set. In automatic selection, night owl and night insect are played every other day. If sw4 of the dip switch 19a selects a piano song,
Automatic selection of piano songs, nocturnes, parting songs, love dreams can be set, and in the case of automatic selection, nokitan, parting songs, love dreams, elise, glitter star variation, French suite, British suite Selected and played in order. Switching of songs during automatic song selection is performed for each performance.

The CPU 20 of the sound source board 14 refers to the time measurement data of the timer 35 in each mode when the dip switch 19a is set to the 3 minute skipping sound mode, the 30 minute once sounding mode or the continuous sounding mode. It is determined whether or not the performance timing has come. If the performance timing is reached, the automatic performance data of the music or natural sound is stored in the RO according to the correspondence shown in FIG. 3 (e) or 3 (f).
M22 is read out and stored in the assignment memory 24, and each part of the sound source board 14 is operated to perform a performance as described above. The CPU 20 functions as a timing determination unit in determining whether or not the performance timing has come.

When the dip switch 19b is operated for selecting a music piece while the mode is set to a mode other than the mute mode, one of the switches sw1 to sw4 is operated to set the state other than all off. Even if the time is not the performance timing, the CPU 20 of the sound source board 14 reads the automatic performance data of the music or natural sound selected by the dip switch 19b from the ROM 22 and stores it in the assignment memory 24. As shown in FIG. 3 (e) or FIG. 3 (f), each part of the sound source board 14 is operated to perform a demonstration performance.

For example, when the switch sw3 of the dip switch 19a is turned off (morning, natural sound), the dip switch 1
When sw1 of 9b is turned off and sw2 is turned on, the morning bird plays one sequence. When sw3 of the dip switch 19a is turned on (morning, piano music) and sw1 of the dip switch 19b is turned off and sw2 is turned on, the prayer of the maiden is 1
The sequence is played. In other cases, the performance of one sequence is similarly performed. In this case, the CPU 20 functions as demonstration performance control means, and the dip switch 19b corresponds to content setting means. To put it just in case, the demonstration performance is only prohibited in the mute mode, and the music selection operation by the DIP switch 19b is not not accepted (the music selection operation is possible even in the mute mode).

As described above, the user can preview how the music or natural sound selected by the user is actually performed.
Therefore, it is possible to confirm how the song or the natural sound is played without waiting until the set performance start time (for example, the start of driving in the morning), and the usability is improved. In addition, the configuration of the operation unit (the DIP switch group 19 in this example) for setting can be simplified. For example, since the display unit of the song title is not required and the special mode is not required, the operation unit and the display control software are not required. No expansion is required, and hardware and software are not complicated.

The above settings can be made by operating the switches sw1 to sw4 of the dip switches 19a and 19b.
It can be used as an alarm by playing M. The setting of the automatic operation start time of the air cleaner 10 is performed by a user's setting operation on the cleaner substrate 13, and the operation is automatically started at the time.
Of course, the user can also start the operation manually. This operation start information is sent from the cleaner board 13 as a type of command to the sound source board 14.
Therefore, at the start of the automatic driving, the BGM performance can be started to wake up.

In particular, when the 3 minute missing sound mode is set, the CPU 20 controls the performance at the start of driving in the morning as follows. At this point, the CPU 20 functions as performance mode control means. [Performance at the start of driving in the morning] First time: Playing for three minutes from the start of driving in the morning Second time: Playing for three minutes from fifteen minutes after starting the driving Third time: Playing for three minutes from two hours after driving starts : Performance for 3 minutes after 2 hours from the previous time Since such a performance mode is adopted, the wake-up effect can be exhibited by the first and second performances. In addition, since the user only needs to set the sound missing mode for 3 minutes (that is, set the performance timing) and does not need to set the performance mode for obtaining the wake-up effect, a wide variety of operations are unnecessary, and the usability is improved. Is improved. Further, the configuration of the operation unit (the DIP switch group 19 in this example) for setting can be simplified. For example, since a display unit of a song name is not required and a special mode is not required, the operation unit and display control software are not required. No expansion is required, and hardware and software are not complicated.

In order to further improve the effect as an alarm, the first performance to the Nth performance (for example, the third performance) are performed at relatively short intervals, and the second performance is performed more than the first performance and the second performance is performed more than the second performance. It is only necessary to increase the tempo or increase the volume of the third time, and the effect can be improved by changing the music in accordance with the number of performances. Further, it is more effective if the configuration is such that the performance is repeated until the stop switch for stopping the performance is operated or the movement of the person (that the user got up and activated) is detected by an infrared sensor or the like. As an example, there is a setting of an alarm performance as follows. [Alarming performance] 1st time: 3 minutes from the start of driving in the morning, splendid waltz, tempo x 0.9, Vol = 60 2nd time: 3 minutes from 15 minutes after the start of driving, splendid waltz, tempo x 1.0, Vol = 70 3rd time: Continuously playing 20 minutes after the start of operation, warship march, tempo × 1.1, Vol = 100 Stopping the performance (returning to the 3 minute gap mode): Stop switch Operation or infrared sensor to detect people.

With such an alarm performance setting,
It can be assumed that many people will wake up freshly in the first or second performance, but if they can not get up by the second performance, the warship march will be played continuously with up tempo and loud sound, It will be an alarm clock. The setting of the songs (brilliant waltz and warship march) is an example, and it goes without saying that other songs may be used. Further, the number of times of performance and the interval thereof are not limited to the above example.

The user's setting operation is easy (just set to the 3 minute gapless sound generation mode), the usability is improved, the configuration of the operation unit for setting can be simplified, and the display unit is not required. This is similar to the above-described example in that no additional components and display control software are required, and neither hardware nor software is complicated.

On the other hand, even if it is set to the sound missing mode for 3 minutes, if it is night (18:00 to 5:00), the CP
U20 is played in the following performance form at the time of the first performance after 21:00, for example. Here, the CPU 20 also functions as performance mode control means. [Sleeping performance] First time: 3 minutes at the first performance timing after 21:00, nocturne, tempo × 1.0, Vol = 70 Second time: performance for 3 minutes following the first time, nocturne, tempo × 1.0 → gradually reduced to 0, Vol = 60. The third and subsequent performances are not performed, the mode is turned off, and the mode returns to the sounding mode (see FIG. 3 (b)) set by the morning driving notification from the cleaner board 13.

In the bedtime performance, the performance tempo is gradually delayed from the middle of the second nocturnal, and the performance is stopped so that the music box with the mainspring stops eventually. This has the effect of bringing the user to sleep. In addition, the user can easily perform the setting operation (just set to the 3 minute missing sound generation mode), the usability is improved, the configuration of the operation unit for the setting can be simplified, and the display unit is not required. In addition, no additional display control software is required, and both hardware and software are not complicated.

As described above, the musical sound generating apparatus of this embodiment has the DIP switch 1 corresponding to the timing setting means.
9a (especially sw1, 2), if the 3 minute missing mode (performance timing) is set, it is not necessary to set even the performance mode in the morning and at bedtime, for example, the number of repetitions of the wake-up performance and the repetition interval This eliminates the need for troublesome setting operations, and improves usability.

Further, in this musical tone generating apparatus, when the user sets the content to be played (natural sound type or music) by the dip switch 19b corresponding to the content setting means, a demonstration performance of the set content is executed. The user can listen to what song and how the song or the like selected by the user is played.

Therefore, it is possible to confirm how the music is played without waiting until the performance start time (for example, the driving start time), and the usability is improved. Furthermore, in the tone generator of the embodiment, the configuration of the operation units (DIP switches 19a and 19b) for setting can be simplified. For example, since the display unit of the music title is not required and the special mode is not required, the operation is not required. No additional components and display control software are required, and hardware and software are not complicated.

The embodiments of the present invention have been described with reference to the embodiments. However, the present invention is not limited to the embodiments, and various modifications can be made without departing from the spirit of the present invention. Needless to say.
