Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a melody system having a timer function.
[0002]
[Prior art]
A device having a conventional general timer function called a so-called timer is designated by a simple single tone or buzzer such as “Chin” when the time specified by the user has elapsed. The user is informed that time has passed. As described above, the conventional timer has a single function, and only performs an operation of generating a sound, vibration, or the like to notify this after a lapse of a designated time (time keeping time). Therefore, the user will not get useful information or other benefits from this timer until the end is sounded, and information such as whether it will soon be over must be seen on the timer scale. I did not understand.
[0003]
For this reason, in the invention disclosed in Japanese Patent Laid-Open No. 150491, a continuous sound that ends at a predetermined time is stored in advance and the continuous sound is played after the power is turned on or until the predetermined time ends. The timer has a function of notifying the elapse and arrival of a predetermined time. Further, according to the present invention, depending on the kind and content of cooking, the music that understands the content of the material is used, or the continuous sound is changed at intervals of 1 minute so that the elapsed time and the remaining time are known. Up to this point, the user can obtain such additional information, and has a function that the conventional timer does not have.
[0004]
[Problems to be solved by the invention]
However, the invention disclosed in Japanese Patent Laid-Open No. 150491 is related to a timer used in a somewhat rough time unit (for example, 1 minute unit), and does not allow fine time setting. In order to enable fine time setting in the present invention, continuous sounds corresponding to each time must be stored in advance for all of the settable times, and a large storage capacity is required to store these continuous sounds. It becomes.
[0005]
The present invention has been made in view of the above points, and it is possible to set a fine timekeeping time and not to simply wait for the passage of time, but to provide a timer function that allows the user to enjoy the waiting time or relax and spend time. A melody system is provided.
[0006]
[Means for Solving the Problems]
According to the first aspect of the present invention, in a melody system having a timer function, loop sound data for repetitive reproduction, end sound data reproduced from a short time before the end to the end time, and each sound data Storage means for storing playback time information, playback means for playing back each of the sound data, input means for receiving an instruction to specify a clock time and start the clock, playback of the specified clock time and each of the sound data Based on the time information, the loop time is set so that the sum of the total playback time of the loop sound data and the playback time of the end time sound data when it is played repeatedly matches or is the closest to the specified time. Calculate the number of repetitions of sound data, and upon receiving an instruction to start timing, first the sound data for the loop for the calculated number of repetitions, and then the sound data for the end time sequentially And control means for reproducing the serial reproduction means is a melody system having a timer function, characterized by comprising.
[0007]
The invention according to claim 2 is the melody system having the timer function according to claim 1, wherein when calculating the number of repetitions of the loop sound data, all of the loop sound data when repeatedly played is calculated. If the sum of the reproduction time and the reproduction time of the end time sound data does not match the designated timing time, the control means further adjusts the reproduction tempo of all or part of each sound data or immediately before the end. By adjusting the volume, the total reproduction time of each piece of sound data is made to coincide with a designated time measurement time.
[0008]
According to a third aspect of the present invention, in the melody system having the timer function according to the first or second aspect, the storage means further corresponds to sound data for informing the remaining time corresponding to the remaining time. The control means causes the reproduction means to reproduce sound data for informing the remaining time corresponding to the remaining time at a predetermined remaining time.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a melody system according to an embodiment of the present invention.
[0012]
In FIG. 1, reference numeral 1a denotes a CPU (Central Processing Unit), which controls the operation of each part of the melody system 1 by executing a control program prepared in advance. Details of the control by the CPU 1a will be described later.
Reference numeral 1b denotes a memory, which includes a ROM (Read Only Memory) and a RAM (Random Access Memory). In this ROM, a control program executed by the CPU 1a, a program for assisting music reproduction processing and voice reproduction processing, sound data for start time to be reproduced at the start of timing, and a loop for repeated reproduction are stored. Three types of sound data, sound data for end time to be played from shortly before the end to the end time, and playback times (playback time information) of the three types of sound data are stored, and the remaining time Is stored in association with predetermined remaining time (for example, 10 minutes (that is, 10 minutes before), 1 minute (that is, 1 minute before), etc.). In addition, a work area of the CPU 1a is set in the RAM.
[0013]
In the present embodiment, each sound data of the start sound data, the loop sound data, and the end sound data is created as MIDI (Musical Instrument Digital Interface) data, and the sound data is separately digitally sampled. Audio data is used.
In this embodiment, as described above, the start sound data to be reproduced at the start of timing, the loop sound data to be repeatedly reproduced, and the end sound to be reproduced from a short time before the end to the end time. The three types of sound data and the reproduction time of these three types of sound data are used, but the start sound data is omitted, loop sound data for repeated reproduction, and a little before the end. It is also possible to use a configuration in which two types of sound data for end time data to be reproduced from the end to the end time and a reproduction time of the two types of sound data are used. In this case, the reproduction time ts of start-time sound data described later is 0 (zero).
[0014]
Reference numeral 1c denotes an input unit provided on the main body of the melody system 1, and a dial for setting the timekeeping or a setting button composed of “0” to “9” for setting the timekeeping time, The input means comprises a timer start button for instructing start and detects input from these buttons. An input value or the like detected by the input unit 1c is given to the CPU 1a.
Reference numeral 1d denotes a display unit composed of an LCD (Liquid Crystal Display) or the like, which displays a set time count, a remaining time during time count, and the like. When the input unit 1c is a dial type, the display unit 1d displays a numerical value indicating the time / remaining time printed on the surface of the main body and an instruction unit (for example, a protrusion) marked on the dial. It shall consist of.
[0015]
Reference numeral 1e denotes a timer unit that measures time and interrupts the CPU 1a at predetermined time intervals. The CPU 1a obtains the elapsed time, the remaining time, and the like based on the interrupt from the timer unit 1e.
The sound source 1f is controlled by the CPU 1a to generate each tone signal based on the start sound data, the loop sound data, or the end sound data, and cause the speaker 1h to reproduce and output each tone. The sound source 1f is assumed to be MIDI compatible here. The sound source 1f reproduces each sound data created as MIDI data as described above.
[0016]
Reference numeral 1g denotes an audio reproduction unit, which receives control from the CPU 1a and generates an audio signal based on the audio data. The audio reproduction unit 1g restores audio data created by digital sampling to an analog audio signal. The generated audio signal is mixed with the musical sound signal generated by the sound source 1f and reproduced / output from the speaker 1h.
Each functional block exchanges data and commands via the bus 10.
[0017]
FIG. 2 shows an example of the appearance (front side) of the melody system 1. In this example, there are provided a dial for setting the time keeping time and an opening for outputting reproduced sound from the speaker 1h. In this example, the numbers, scales, and dial protrusions printed on the surface correspond to the display portion 1d. In this example, the start button is not provided, but the timing is started simultaneously with the end of the setting of the timing time by the dial.
[0018]
Next, the operation of the melody system 1 of the present embodiment configured as described above will be described with reference to FIG.
[0019]
First, a user inputs a time setting (timer setting) using the setting button of the input unit 1c of the melody system 1 body, and further receives a time start instruction input from the timer start button (step S11). .
Next, the number of repeated reproductions of the loop sound data (number of loops = n) is calculated from the time measured and input at step S11, and an end method at the end of time measurement is determined (step S12). Details of this process will be described later.
[0020]
Next, the CPU 1a acquires the start time sound data from the memory 1b, and gives the start time sound data to the sound source 1f. Then, the sound source 1f reproduces the start song based on the start sound data (step S13).
Further, the CPU 1a acquires the loop sound data from the memory 1b when the reproduction time of the start time sound data elapses, and gives it to the sound source 1f. The sound source 1f reproduces a loop song based on the loop sound data (step S14).
Next, the CPU 1a determines whether it is 10 seconds before the end (step S15). In addition, 10 seconds before the end is an example, and the timing is determined separately.
[0021]
If it is determined in step S15 that it is 10 seconds before the end (Yes in step S15), the CPU 1a acquires sound data that informs 10 seconds before as the remaining time from the memory 1b. This is given to the audio reproduction unit 1g. The sound reproducing unit 1g reproduces sound (for example, “10 seconds left”) based on the sound data (step S16). In this way, the notification sound corresponding to the remaining time is reproduced in synchronization with the remaining time at a predetermined timing. This is performed, for example, at the timing of the remaining remaining time as the remaining time until the end based on the information on how many times the loop music is reproduced. Of course, this timing can be set at an arbitrary time measured by the CPU 1a based on the signal from the timer unit 1e.
[0022]
On the other hand, if it is determined in step S15 that it is not 10 seconds before the end (determination of No in step S15), the process proceeds to step S17.
In step S17, it is determined whether the current number of repetitions has reached the number of loops n calculated in step S12. At the present stage, since the number of repetitions is one, it is determined No and the process returns to step S14 to replay the loop music.
As described above, the processing from step S14 to step S17 is repeated until the number of loop music reproductions reaches the number of loops n.
[0023]
Here, it is assumed that the loop music reproduction repeat count reaches the loop count n.
Then, it determines with Yes by judgment of step S17, and moves to step S18.
In step S18, the CPU 1a obtains end-time sound data from the memory 1b, and provides this end-time sound data to the sound source 1f. The sound source 1f reproduces the end song based on the end-time sound data by the end method determined in step S12.
When the playback of the end song in step S18 is finished, the CPU 1a acquires sound data notifying that the remaining time has run out (finished) from the memory 1b, and a sound based on this sound data (for example, “finished” ") Is reproduced (step S19).
The above is the operation flow of the melody system 1 of the present embodiment.
[0024]
In the above, it is assumed that the processing time for determining the number of loops and the termination method can be ignored. If the processing time for determining the number of loops and the end method cannot be ignored, perform the processing after setting the timer by the user, and accept the timer start instruction after determining the number of loops and the end method. Try to play. Alternatively, after receiving the timer start instruction, the start song may be played first, and the number of loops and the end method may be determined during playback of the start song.
[0025]
Here, the details of the process for determining the number of loops and the termination method in step S12 will be described with reference to FIG.
Below,
T: Timer timing,
ts: playback time of start sound data,
te: Playback time of end sound data,
tl: Loop sound data playback time,
And In addition, the following normal mode, tempo slow mode, and fade-out mode are provided as types of termination methods (details will be described later).
[0026]
As shown in FIG. 4, first, (T-ts-te) / tl is calculated to obtain a quotient n and a remainder α (step S121).
Then, it is determined whether or not the remainder α obtained in step S121 is 0 (zero) (step S122).
Next, if it is determined in step S122 that α = 0 (Yes in step S122), the process proceeds to step S123.
In step S123, the loop count is set to n obtained in step S121, and the normal mode is selected as the end method.
On the other hand, if it is determined in step S122 that α = 0 is not satisfied (No in step S122), the process proceeds to step S124.
[0027]
In step S124, it is further determined whether or not the remainder α obtained in step S121 is α ≦ tl / 2.
If it is determined in step S124 that α ≦ tl / 2 (Yes in step S124), the process proceeds to step S125.
Next, in step S125, the loop count is set to n obtained in step S121, and the tempo slow mode is selected as the end method.
On the other hand, if it is determined in step S124 that α ≦ tl / 2 is not satisfied (No in step S124), the process proceeds to step S126.
In step S126, the loop count is set to n + 1 obtained by adding 1 to n obtained in step S121, and the fade-out mode is selected as the end method.
[0028]
As a specific example of the above processing, when ts = 10 seconds, tl = 2 seconds, te = 10 seconds, and T = 1 minute (= 60 seconds), (T−ts−te) / tl = (60−10−) 10) / 2 = 20, 20 is obtained as the quotient n, and 0 is obtained as the remainder α. In this example, the start song based on the start sound data is reproduced for 10 seconds, and then the loop song based on the loop sound data is reproduced 20 times, 2 seconds × 20 = 40 seconds, and then the end sound data is obtained. The end music based is played for 10 seconds and finished. In addition, at a predetermined timing from the start to the end, a notification sound corresponding to the remaining time is reproduced in synchronization with the remaining time.
The above is the details of the process for determining the loop count and the termination method in step S12.
[0029]
Next, the normal mode, tempo slow mode, and fade-out mode will be described.
(1) In normal mode, as shown in FIG. 5, the sum of the reproduction time ts of the start sound data, the total reproduction time tl × n of the loop sound data, and the reproduction time te of the end sound data is When the measured time T of the designated timer coincides, that is, when ts + tl × n + te = T, the start-time sound data is first reproduced, and then the calculated number of loops (ie, n times) In this mode, the loop sound data is reproduced, and then the end sound data is reproduced and terminated. Therefore, the total reproduction time of each sound data in the normal mode is ts + tl × n + te, and the measured time T = total reproduction time ts + tl × n + te.
[0030]
(2) In the tempo slow mode, as shown in FIG. 6, the sum of the reproduction time ts of the start sound data, the total reproduction time tl × n of the loop sound data, and the reproduction time te of the end sound data. Start when the time count T of the designated timer does not match and the remainder α calculated in step S121 is equal to or less than tl / 2, that is, α ≦ tl / 2. The reproduction of the time sound data and the reproduction of the loop sound data are the same as in the normal mode. However, when the end time sound data is reproduced, the tempo is extended and the reproduction time te ′ is set to the original reproduction time te. In this mode, the end-time sound data is reproduced and ended so that te + α is added. Therefore, the total reproduction time of each sound data in the tempo slow mode is ts + tl × n + te ′, where te ′ = te + α, and the measured time T = total reproduction time ts + tl × n + te ′.
[0031]
(3) In the fade-out mode, as shown in FIG. 7, the sum of the reproduction time ts of the start sound data, the total reproduction time tl × n of the loop sound data, and the reproduction time te of the end sound data is If the time count T of the designated timer does not match, and if the remainder α calculated in the above step S121 exceeds tl / 2, that is, α> tl / 2, the number of loops is set. The quotient n obtained in step S121 is set to n + 1, and the reproduction time te ”of the end sound data in this mode is set to te− (tl−α), and the end sound data is reproduced. In this mode, the volume is gradually attenuated, and the sound is muted and terminated at the end, so the total reproduction time of each sound data in the fade-out mode is ts + tl × (n + 1) + te. “However, te” = te− (tl−α), and the measured time T = total reproduction time ts + tl × (n + 1) + te ”.
[0032]
In this embodiment, MIDI sound data is used. In MIDI, tempo change and volume change (including fade-out) can be freely performed. The tempo slow mode and the fade-out mode in the present embodiment are realized by changing tempo information, volume information, and the like included in end sound data to be given to the sound source 1f based on the MIDI standard.
[0033]
As another embodiment, three types of sound data, that is, start sound data, loop sound data, and end sound data can be set instead of separately (the user can input from the input unit 1c). A plurality of pieces of sound data are prepared in advance, in which three types of sound data of start time sound data, loop sound data and end time sound data are combined into one, each of which can be set as a reproduction time. Alternatively, it may be configured to store in correspondence with a settable time and reproduce sound data corresponding to the designated time when reproducing. In this case, the processing for calculating the number of repetitions of the loop sound data can be omitted, and the reproduction can be terminated at the designated timed time without the need to adjust the reproduction tempo or volume.
[0034]
The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration and each operation flow are not limited to this embodiment, and the configuration and the like without departing from the gist of the present invention. Is also included. For example, in the above-described embodiment, the playback tempo and the volume are adjusted with respect to the playback of the end-time sound data in order to end at the designated time, but the start-time sound data and The specified time measurement may be satisfied by adjusting the tempo over the entire reproduced sound based on the loop sound data and the end sound data.
[0035]
【The invention's effect】
As described above in detail, according to the present invention, during the time measurement of the designated time measurement, the loop sound data is first reproduced for the calculated number of repetitions, and then the end time sound data is reproduced. Since playback is performed, the played sound changes in order. By changing to the reproduced sound based on the end-time sound data in this way, it can be seen that the remaining time is short, and there is no need to confirm the remaining time. Also, the time you just waited becomes a fun and relaxing time.
In addition, according to the present invention, the playback tempo of all or part of each sound data is adjusted or the volume just before the end is adjusted so that the total playback time of each sound data matches the specified time. , Fine time setting can be set.
According to the present invention, the sound data for notifying the remaining time corresponding to this timing is reproduced at the timing of the predetermined remaining time, so that the remaining time can be understood in more detail.
