  However, in the musical instrument described in Patent Document 1, the comfort due to negative ions is not linked to the performance and only gives a certain negative ion effect even if there is an inflection of the performance.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a musical instrument and a performance system capable of adjusting the effect to a change in performance in an instrument capable of generating effects other than performance. To do.

The present invention acquires performance data from a musical instrument body performed by a performer , counts the number of notes included in the acquired performance data, and determines whether the counted number of notes exceeds a predetermined threshold. wherein the player state specifying means for specifying a state of the player, in response to a control signal supplied, and release means for releasing the fine particles of a given fragrance particles or predetermined negatively charged by, There is provided a musical instrument having control means for generating a control signal for controlling release by the discharge means according to the state of the performer specified by the player state specifying means and supplying the control signal to the discharge means. .
According to this instrument, it is possible according to the state of the performer, to release fine particles tinged predetermined fragrance particulate or negative charge around the instrument. Therefore, by using this musical instrument, the performer can be relaxed and the comfort of performance can be improved.

Hereinafter, first to fourth embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a block diagram showing a configuration of a keyboard instrument 1 according to the first embodiment.
The keyboard 11 includes a plurality of keys, and MIDI (Musical Instruments Digital Interface) data MD such as a note-on message including a key code of a pressed key and a note-off message including a key code of a released key. Output.

The sound source 12 corresponds to the MIDI standard, and receives music data MD from the keyboard 11 to generate musical sounds. More specifically, when the MIDI data MD is a note-on message, generation of a tone corresponding to the key code in the message is started, whereas in the case of a note-off message, the tone data is generated according to the key code in the message. The sound is muted.
The speaker 13 emits the musical sound generated by the sound source 12.

  The ion emission unit 14 generates negative ions (negatively charged fine particles) and releases them to the outside of the keyboard instrument 1, and starts / stops emission in response to a control signal. The method of generating negative ions is arbitrary, and for example, a water crushing method (Leonard method), an electron emission method, or a corona discharge method may be used.

  A CPU (central processing unit) 17 controls each part of the apparatus based on a program P 1 stored in the ROM 15. A RAM (Random Access Memory) 16 temporarily stores data and is used as a work area of the CPU 17. The timer T outputs a time-out signal when the elapsed time from the start reaches a predetermined time-out time.

  FIG. 2 is a flowchart of processing performed by the CPU 17. As shown in this figure, the CPU 17 first performs an initial setting. One of the initial settings is a process of setting the note number register set in the RAM 16 to “0” (step S1). Next, it is determined whether or not a time-out signal of the timer T is output (step S2). If “NO”, the process proceeds to step S3 to determine whether or not a signal is supplied from the keyboard 11 (step S3). . If this determination is “NO”, the process returns to step S2.

  On the other hand, when the performer starts playing using the keyboard 11, note-on or note-off MIDI data MD including the key code of the played key is output from the keyboard 11 and input to the sound source 12. The tone generator 12 appropriately performs generation and mute processing according to the key code in the input MIDI data MD, and the generated tone signal is emitted from the speaker 13.

While the performance is being performed as described above, the process shown in FIG. 2 proceeds from step S2 to step S3 to step S4. And if the signal output from the keyboard 11 is note-on, it will progress to step S5, and if it is other than note-on, it will return to step S2 again. In step S5, the CPU 17 adds “1” to the note number register. Next, proceeding to step S6, it is determined whether or not the value of the note number register exceeds the threshold value. If “NO”, the process returns to step S2 to repeat the above-described processing.
By repeating the above steps S2 to S6, the value of the note number register is gradually increased. When the performer simultaneously presses a plurality of keys, the value in the note number register increases by the number of keys pressed. If the value of the note number register exceeds a preset threshold value (for example, “1000”) in step S6, the process proceeds to step S7 to start the timer and reset the note number register. . Then, the process proceeds to step S9, and a control signal for releasing negative ions is sent to the ion emitter 14 and the process returns to step S2. Thereby, negative ions begin to be released to the outside of the keyboard instrument 1.

Thereafter, the above-described processing is repeated. However, since negative ions are released around the performer, the negative ion concentration increases in the space. Thus, when the performance progresses to some extent, negative ions are released around the performer.
Release of negative ions continues until a time-out signal is output from the timer T. However, since the timer T is reset every time a MIDI event is generated, a time-out signal is not output during performance.

  On the other hand, when the performer finishes playing and reaches the timeout time, a timeout signal is output from the timer T, and the CPU 17 sends a control signal for stopping the emission of negative ions to the ion emitter 14 (step S10). . Thereby, the release of negative ions is stopped (step S2 → S10).

  As described above, the keyboard instrument 1 obtains the number of played notes using the MIDI data MD of the note-on message, and when the obtained number of notes exceeds a predetermined threshold, negative ions are detected by the keyboard instrument 1. Release to the surroundings. Here, since the number of played notes corresponds to the progress degree of the performance, the keyboard instrument 1 detects the progress degree of the performance, and thereby specifies the performance state. The performance state is specified depending on how the threshold value is set, but can be arbitrarily specified such as the initial state of the performance, the state in which the performance has progressed in the middle, or the state in which the performance has reached the end. In addition, since the number of notes when the music reaches the climax is known in advance, if the value is set as a threshold value, it can be specified that the performance state has reached the climax. And, negative ions are released according to the specific result of the performance state. For example, when the performance progresses in the middle and the performer begins to get tired, the negative ions relax the performer or the song reaches the climax. The negative ions will moderate the player's tension moderately, or when the song enters a quiet scene, the negative ions will make the performer comfortable and guide the performance along the tone. Can do.

[Second Embodiment]
FIG. 3 is a block diagram showing the configuration of the keyboard instrument 2 according to the second embodiment.
As shown in this figure, the keyboard instrument 2 includes a ROM 21, a light emitting unit 22, a display unit 23, a music selection button B1, a start button B2, and a CPU 24, and a keyboard 11, a sound source 12, a speaker 13, an ion common to FIG. The discharge unit 14 and the RAM 16 are included.

In the figure, the CPU 24 controls each part of the apparatus based on a program P2 in the ROM 21. In addition, n pieces of music data M1, M2,..., Mn are sequentially written in the ROM 21, and the contents of the music data are shown in FIG.
As shown in FIG. 4, the music data has a music title E1 indicating the name of the music, and key release data E2 for performance guidance indicating which key is pressed and released to the performer. The key release data E2 includes key press data for each note for guiding the key press and key release data for each note for guiding the key release. In this case, the key pressing data includes a key code of the key and timing information indicating the timing at which the key is pressed, and the key release data includes timing information indicating the key code of the key and the timing at which the key is released.
In addition, the music data includes release start information E3 that instructs the release of negative ions. The release start information E3 indicates the release start timing of negative ions according to the elapsed time from the start timing of the music data. Similarly, the music data includes release stop information E4 for stopping the release of negative ions. This release stop information E4 indicates the stop timing of the negative ions according to the elapsed time from the start timing of the music data.

The light emitting unit 22 includes the same number of LEDs (Light Emitting Diodes) as the keys of the keyboard 11, and each LED is installed in the vicinity of the corresponding key. These LEDs light up to guide key presses and turn off to guide key release. The display unit 23 is for displaying the song name E1 of the song data.
The music selection button B1 is for selecting one music data from the music data M1, M2,..., Mn, and outputs a selection signal SB1 when pressed.
The start button B2 is a button that is pressed when instructing the start of performance guidance, and outputs a start signal SB2 when pressed.

5 to 8 are flowcharts of processing performed by the CPU 24.
As shown in FIG. 5, the CPU 24 first selects the first music data M1 (step S21), reads the selected music data M1 from the ROM 21 (step S22), and displays the music title E1 on the display unit 23 ( The process proceeds to step S23) and step S24. In step S24, it is determined whether or not any signal is supplied to the CPU 24, and the determination process in step S24 is repeated until this determination is “YES”. When any signal is supplied to the CPU 24, the determination in step S24 is “YES”, and the process proceeds to step S25.

In step S25, it is determined whether or not the signal supplied to the CPU 24 is the selection signal SB1, that is, whether or not the music selection button B1 has been pressed. If this determination is “YES”, the CPU 24 selects the next music data M2, and returns to step S22. Similarly, every time the music selection button B1 is pressed, the processing of step S24 → step S25 → step S26 is performed, so that music data M3, M4... Are sequentially selected and the music of the music is displayed on the display unit 23. The song name is displayed. The user can select a desired song by pressing the song selection button B1 in this way.
On the other hand, when the determination in step S25 is “NO”, the process proceeds to step S27, and it is determined whether or not the signal received by the CPU 24 is the start signal SB2. If this determination is “NO”, the process returns to step S24, and if “YES”, the process proceeds to step S28. In step S <b> 28, the CPU 24 executes in parallel the press / release key guidance process shown in FIG. 6, the release start process shown in FIG. 7, and the release stop process shown in FIG. 8.

In the key release key guidance process of FIG. 6, the CPU 24 reads the key release data E2 of the music data Mk (k is 1 to n) that is selected at that time, and each key press data included therein, It is determined from the timing information of the key release data whether or not the timing to be processed has come (step S32). If this determination is “NO”, the process waits until the processing timing comes, and if “YES”, the process is started (step S33).
If the key release data at the timing to be processed is the key press data, the determination in step S34 is “YES”, and the CPU 24 is in the vicinity of the key corresponding to the key code indicated by this key press data. The light emitting unit 22 is controlled so as to light the LED (step S35).

On the other hand, if the pressed / released key data at the timing to be processed is key release data, the determination in step S34 is “NO”, and the CPU 24 is in the vicinity of the key corresponding to the key code indicated by the key release data. The light emitting unit 22 is controlled to turn off the LED (step S36). After the process in step S35 or step S36, the process returns to step S32 via step S38, and the above-described process is repeated. That is, the LEDs in the vicinity of the key to be depressed are sequentially turned on, and the LEDs in the vicinity of the key to be released are sequentially turned off. In this way, the LED blinks and the key press is guided. The performer can perform a performance according to the music data Mk by pressing and releasing keys according to the guidance.
The above key release guidance process ends when all the data in the key release data E2 of the music data Mk has been processed (step S38).

  On the other hand, in the release start process of FIG. 7, the CPU 24 determines that the elapsed time from the start of the press / release key guidance process reaches the release start time indicated by the release start information E3 of the selected music data Mk. Wait (step S41). When the elapsed time reaches the release start time, the determination result in step S41 is “YES”, and the CPU 24 causes the ion release unit 14 to release negative ions.

  Further, in the release stop process shown in FIG. 8, the CPU 24 reaches the release stop time indicated by the release start information E3 of the selected music data Mk after the elapsed time from the start of the press / release key guidance process. (Step S51). When the elapsed time reaches the emission stop time, the determination result in step S51 is “YES”, and the CPU 24 issues an instruction to the ion emission unit 14 and stops the emission of negative ions.

  By the above processing, negative ions are released from the release start time to the release stop time. Therefore, as in the first embodiment described above, the performance state indicating how much the performance has progressed or in which part the performance is located is specified by the release disclosure time and the release stop time, and according to this specification result. Releases negative ions.

[Third Embodiment]
FIG. 9 is a block diagram showing the configuration of the keyboard instrument 3 according to the third embodiment.
As shown in this figure, the keyboard instrument 3 includes a pulse wave detection sensor 31, a ROM 32, a RAM 33, and a CPU 34, and a keyboard 11, a sound source 12, a speaker 13, and an ion emitter 14 that are common to those in FIG.

The pulse wave detection sensor 31 detects and outputs a volume pulse wave from the earlobe, and has a clip for mounting on the player's earlobe. The pulse wave detection sensor 31 and the main body of the keyboard instrument 3 are connected by a signal line for transmitting the volume pulse wave output from the pulse wave detection sensor 31.
The CPU 34 reads out and executes the program P3 from the ROM 32, and controls each part of the apparatus. The RAM 33 is for temporarily storing data. In the embodiment, the CPU 34 executes in parallel the process of receiving the volume pulse wave output from the pulse wave detection sensor 31 attached to the performer's earlobe and writing it into the RAM 33 and the release control process shown in FIG.

  In the release control process, the CPU 34 first secures the flag F in the storage area of the RAM 33 and writes “0” in the secured flag F (step S61). Next, the CPU 34 determines whether or not a volume pulse wave for a period sufficient to obtain the high tide level of the player's feeling is written in the RAM 33 (step S62). Immediately after the start of the pulse wave detection process, the determination result is “NO”, and the determination in step S62 is repeated.

  When a certain amount of time has elapsed and the determination result in step S62 is “YES”, the CPU 34 performs frequency analysis on the volume pulse wave of the latest period written in the RAM 33, and performs a high frequency component (for example, 0.04 to 0). LF / HF, which is a ratio of low frequency components (for example, 0.15 to 0.4 Hz) to .15 Hz components), is regarded as a high tide level of the player's feelings (step S63). Next, it is determined whether or not the calculated storm surge exceeds a preset threshold value (step S64).

  If the determination result of step S64 is “NO”, the CPU 34 determines whether or not the flag F is “1” (step S65). Since “0” is written in the flag F by the process of step S61, the determination result is “NO”. Therefore, the process returns to step S63.

  Thereafter, while the determination result of step S64 is “NO”, that is, while the player's feelings are not high tide and in a calm state, step S63 → step S64 → step S65 is circulated.

  Here, when the performer enters into the climax of the song and the part of his thoughts, the player's feelings rise. As a result, the determination result of step S64 is “YES”. Then, the CPU 34 determines whether or not the flag F is “0” (step S66), the determination result is “YES”, and the CPU 34 causes the ion emission unit 14 to emit negative ions. (Step S9). Next, the CPU 34 writes “1” in the flag F (step S67) and returns to step S63.

  Thereafter, while the player's feelings are high, the determination result in step S64 continues to be “YES”. Therefore, the process of step S64 → step S66 → step S9 → step S67 is circulated and minus from the ion emitter 14. Ions continue to be released.

  When the player's feelings are calmed down, the LF / HF value decreases. When this value is less than or equal to the threshold value, the determination result in step S64 is “NO”, and it is determined in step S65 whether or not the flag F is “1”. This determination is “YES”, and the process of step S10 is performed. This stops the release of negative ions. Next, the CPU 34 writes “0” in the flag F (step S68), and returns to step S63. By the above processing, negative ions are released during a period when the player's feelings are high. In this case, which part of the song storm surges and how many times the storm surge occurs depends on the individuality of the player, but in this embodiment, negative ions can be released in accordance with the player.

  As described above, the keyboard instrument 3 detects the player's plethysmogram to determine the tide level of the player's feelings, and when this tide level exceeds a threshold value, negative ions are released around the keyboard instrument 3. To do. Since the high tide level of the performer's feeling indicates the performance state (for example, intensity / calmness), the keyboard instrument 3 identifies the performance state by detecting the high tide level, and the minus is determined according to the identification result. Releases ions.

[Fourth Embodiment]
FIG. 11 is a diagram showing a configuration of the performance system 4 according to the fourth embodiment. The performance system 4 includes a speaker device 5 arranged near the audience at a concert venue, a keyboard instrument 6 on the stage, a microphone 7 that collects musical sounds emitted from the keyboard instrument 6, and musical sounds collected by the microphone 7. And an amplifier 8 that supplies the signal to the speaker device 5.

  The speaker device 5 includes a speaker 51, a receiving unit 52, and an ion emitting unit 14. The speaker 51 emits a musical tone supplied from the amplifier 8, and the receiving unit 52 receives a signal from the keyboard instrument 6 and transfers the received signal to the ion emitting unit 14.

The keyboard instrument 6 includes a transmission unit 61, a ROM 62, and a CPU 63, a keyboard 11, a sound source 12, a speaker 13, a RAM 16, and a timer T that are the same as those in FIG.
The transmission unit 61 transmits the control signal supplied from the CPU 63 to the ion emission unit 14 and transmits the control signal to the speaker device 5.
The CPU 63 reads out and executes the program P4 from the ROM 62, and controls each part of the apparatus. In the present embodiment, the CPU 63 performs the same process as in FIG. However, the CPU 63 uses the transmission unit 61 to perform processing for sending a control signal to the ion emission unit 14.

  According to the performance system 4, when the performer plays the keyboard instrument 6, musical sounds corresponding to the performance are generated by the sound source 12 and supplied to the speaker device 5 through the speaker 13, the microphone 7 and the amplifier 8, and from the speaker 51. Sound is emitted.

  On the other hand, the CPU 63 of the keyboard instrument 6 supplies a control signal for starting emission to the transmitter 61 when the number of notes played using the keyboard instrument 6 (value of the note number register) exceeds a threshold value. To do. This control signal is transmitted from the transmission unit 61, received by the reception unit 52 of the speaker device 5, and transferred to the ion emission unit 14. As a result, negative ions are released around the speaker device 5. The release of negative ions continues until the performance ends and the timer T times out.

  As described above, the performance system 4 can improve the comfort of performance by detecting the performance state of the keyboard instrument 6 and releasing negative ions around the speaker device 5 according to the detection result.

[Modification]
The first to fourth embodiments described above may be modified as listed below.
For example, a keyboard instrument or a speaker device may be provided with a scent discharge part that discharges scent fine particles, and instead of negative ions, the scent fine particles may be released. If the scent microparticles released in this embodiment are scent microparticles such as “jasmine” and “mint” that have a positive effect on health, the comfort of performance is improved. In addition, the scent discharge unit is provided with a plurality of chambers that can contain scent fine particles and an operation element that instructs the selection of one of the chambers. The scent discharge unit receives a control signal from the CPU, The scented fine particles may be released from the chamber selected by the operation element. In addition, the scent discharger is provided with a plurality of chambers as described above and a scent selection means for instructing selection of one of the chambers according to the detected performance state. The scent discharger receives a control signal from the CPU. Then, the scent fine particles may be released from the chamber selected by the scent selecting means.

  Further, for example, a keyboard instrument or a speaker device is provided with an air discharge unit that generates and discharges high-concentration oxygen air having an oxygen concentration of about 30% so that the high-concentration oxygen air is discharged instead of negative ions. It may be. The method for generating high-concentration oxygen air is arbitrary, and for example, a method using an oxygen-enriched film or a method using a spray of concentrated oxygen may be used. Since high-concentration oxygen air has a positive effect on health, gas molecules constituting high-concentration oxygen air also have a positive effect on health.

For example, not only negative ions, scented fine particles, and high-concentration oxygen air, but also fine particles having any healing effect may be released. The term “fine particles having a healing effect” is a concept that makes a person feel “healing” and includes fine particles that adsorb odor molecules in the air and are not brominated. Further, for example, the discharge amount of negative ions or the like may be changed according to the performance state.
Moreover, you may apply to arbitrary musical instruments other than a keyboard musical instrument. For example, the present invention can also be applied to acoustic stringed instruments such as guitars and violins. In this case, the sound of these musical instruments can be picked up by a microphone, and the performance state can be specified from the detection result. Then, the emission of fine particles is controlled according to the performance duration and volume.

Further, for example, in the first and fourth embodiments, similarly to the third embodiment, the release of negative ions may be controlled according to the intensity of performance. In addition, as a method of detecting the intensity of performance using MIDI data MD, for example, a method of obtaining the intensity of performance by determining the number of notes played within a unit time, or the intensity of performance based on the strength of keystrokes. There are ways to find out. In this case as well, in both the first and fourth embodiments, the performance state may be detected using a musical tone signal different from the MIDI data.
Also, the second and third embodiments may be modified to provide a performance system having a keyboard instrument and a speaker device as in the fourth embodiment. In the third embodiment, the keyboard instrument 3 is changed to an acoustic keyboard instrument. May be.
As described above, the performance state may be specified from the ecological information of the performer, or may be specified using a microphone or other pickup (such as a piezoelectric sensor) in the case of an acoustic instrument. Further, in the case of an electronic musical instrument that generates MIDI data, the generated MIDI data itself becomes a musical tone signal, so that various performance states can be specified using key-on and key velocity in the MIDI data.
