[First Embodiment]
FIG. 1 is a diagram showing a configuration of a musical instrument excitation apparatus 1 according to a first embodiment of the present invention. The musical instrument excitation device 1 is a portion surrounded by an alternate long and short dash line, and 2 is a trumpet. Reference numeral 21 denotes a mouthpiece, and 20a, 20b, and 20c are piston valves. Piston solenoids 22a, 22b, and 22c are respectively arranged on the upper portions of the piston valves 20a, 20b, and 20c, and are arranged so that the axis of the plunger is the same as the axis of the corresponding piston valve. . As a result, the piston solenoids 22a, 22b, and 22c can respectively press down the corresponding piston valves. Since the trumpet 2 is a general trumpet, description of the other components is omitted.

  In the figure, reference numeral 11 denotes a storage unit including a storage device such as a ROM (Read Only Memory) or a hard disk. As illustrated, the storage unit 11 stores drive waveform automatic performance data D1 and fingering automatic performance data D2. The drive waveform automatic performance data D1 is audio waveform data that records vibrations of a predetermined part of the mouthpiece of the trumpet that is being played. Therefore, if the drive waveform automatic performance data D1 is sequentially read according to the progress of the music, the vibration waveform at the predetermined part of the mouthpiece is reproduced. The fingering automatic performance data D2 is performance operation information indicating operation contents of the trumpet piston valves 20a, 20b, and 20c, and is operation information corresponding to the drive waveform automatic performance data D1. More specifically, the data corresponds to the pitch of the drive waveform automatic performance data and is stored along with the progress of the performance. The fingering automatic performance data D2 is generated based on the detection signal of the sensor in the actual performance, for example, by providing a sensor for detecting the movement of the piston valve of the trumpet. That is, the fingering automatic performance data D2 is a pair of data indicating the state of the piston valves 20a, 20b, and 20c (piston state information) and a time interval (hereinafter referred to as gate time) until this state changes. Consists of. These are just similar to the relationship between MIDI signal events and duration data indicating their intervals.

  12 is a tempo designating unit for designating a tempo, and 13 is a pitch designating unit for designating a pitch. A tempo / pitch changing unit 14 corrects the waveform data in accordance with the tempo and pitch specified by the tempo specifying unit 12 and the pitch specifying unit 13. The tempo / pitch changing unit 14 reads the drive waveform automatic performance data D1 stored in the storage unit 11, and corrects the read waveform data to the one corresponding to the designated tempo and pitch.

  The tempo and pitch may be appropriately specified in real time during the reproduction (performance) of the music, or designation information for specifying which part of the music to change the tempo and pitch in the storage unit 11 in advance. You may make it memorize | store it. When changing the tempo and pitch in real time, the instrument excitation device 1 is provided with an operation unit for inputting tempo information and pitch information, and the user can appropriately input the tempo information through the operation unit. You may do it. In the case where designation information for designating the tempo and pitch is stored in the storage unit 11 in advance, the tempo designation unit 12 and the pitch designation unit 13 are sent to the tempo / pitch changing units 14 and 17 in accordance with the stored designation information. Specify the tempo and pitch.

  Here, the tempo and pitch changing method performed by the tempo / pitch changing unit 14 will be described. FIG. 2 is a diagram schematically showing a pitch changing method performed by the tempo / pitch changing unit 14. In the figure, A1 shows an example of the waveform of the drive waveform automatic performance data. The tempo / pitch changing unit 14 processes the waveform A1 to the waveform A2 by performing expansion / contraction operations (compression, expansion, etc.) in the time direction on the waveform A1. When this expansion / contraction calculation is performed, the tempo is also changed, but when the pitch change amount is small, the tempo change amount is also small, so that it can be used as a pitch changing method.

  FIG. 3 is a diagram schematically showing a tempo changing method performed by the tempo / pitch changing unit 14. In the figure, A3 shows an example of the waveform of the drive waveform automatic performance data. The tempo / pitch changing unit 14 performs time stretching processing for compressing the waveform in the time direction without changing the pitch with respect to the waveform A3, and processes the waveform A3 into the waveform A4. Specifically, a waveform repetition is sequentially added to perform waveform time stretching. In this case, the tempo is delayed by the amount of time stretch.

  Next, a case where both the tempo and the pitch are changed will be described with reference to FIG. In FIG. 4, for convenience of explanation, the tempo / pitch change unit 14 is divided into a tempo change unit 14A and a pitch change unit 14B. When changing the tempo and pitch, first, the pitch is changed. This change is performed in the same manner as shown in FIG. At this time, when the pitch is changed from f1 [Hz] to f2 [Hz], the waveform size becomes (f1 / f2) times. FIG. 4 shows a waveform A5 before processing and a waveform A6 after processing when the pitch is doubled. Next, when changing the tempo from T1 [beats / minute] to T2 [beats / minute], it is necessary to increase the size of the waveform by (T1 / T2) times, but in order to correct the size change due to the pitch change. The waveform size is adjusted as (T1 / T2) × (f2 / f1) times. FIG. 4 shows a case where the pitch is doubled and the tempo is doubled, and the waveform A6 is changed to the waveform A7. Here, by adjusting the waveform size as described above, the waveform sizes of the waveform A5 and the waveform A7 become the same as shown in FIG.

  Returning to the description of FIG. A vibration actuator 15 is attached to the inside of the mouthpiece 21 of the trumpet 2 and performs excitation according to the waveform data supplied. Reference numeral 16 denotes a vibration actuator driving unit that vibrates the vibration actuator 15 in accordance with the waveform data supplied from the tempo / pitch changing unit 14.

Reference numeral 17 denotes a tempo / pitch changing unit that changes performance operation information in accordance with the tempo and pitch specified by the tempo specifying unit 12 and the pitch specifying unit 13. The tempo / pitch changing unit 17 reads the fingering automatic performance data D2 stored in the storage unit 11, and corrects the read performance operation information according to the designated tempo and pitch. More specifically, the tempo / pitch changing unit 17 rewrites the piston state information of the fingering automatic performance data D2 so as to correspond to the changed pitch, and rewrites the gate time according to the changed tempo. . In this case, rewriting of the piston state information is such that the piston state information corresponding to the pitch after the change can be immediately read out by a rewriting table prepared in advance.
Reference numeral 18 denotes a fingering actuator driving unit that performs driving control on the piston solenoids 22a, 22b, and 22c in accordance with performance operation information supplied from the tempo / pitch changing unit 17. The fingering actuator driving unit 18 determines the piston valve to be pressed and the pressing amount among the piston valves 20a, 20b, and 20c of the trumpet 2 according to the fingering automatic performance data D2. And a drive current is sent through the solenoids 22a-22c for pistons corresponding to the determined piston valve, and the said piston valve is pressed down.

  The operation of this embodiment having the above-described configuration is as follows. The tempo / pitch changing unit 14 of the musical instrument excitation device 1 reads drive waveform automatic performance data D1 from the storage unit 11. At this time, when the tempo or pitch is specified by the tempo specifying unit 12 or the pitch specifying unit 13, the tempo / pitch changing unit 14 changes the tempo or pitch according to the specified contents, and the changed waveform data is displayed. The vibration actuator driving unit 16 is supplied. When the tempo or pitch is not designated, the read waveform data is supplied to the vibration actuator driving unit 16 as it is. On the other hand, the tempo / pitch changing unit 17 reads the fingering automatic performance data D2 from the storage unit 11. At this time, when the tempo or pitch is specified by the tempo specifying unit 12 or the pitch specifying unit 13, the tempo / pitch changing unit 17 changes the tempo or pitch according to the specified content and drives the fingering actuator. The changed data is supplied to the unit 18. When the tempo or pitch is not designated, the read fingering data is supplied to the fingering actuator driving unit 18 as it is.

  The vibration actuator drive unit 16 drives the vibration actuator 15 according to the supplied waveform data. In addition, the fingering actuator driving unit 18 drives the piston solenoids 22a, 22b, and 22c based on the operation information supplied from the tempo / pitch changing unit 17. At this time, the vibration actuator driving unit 16 and the fingering actuator driving unit 18 drive the vibration actuator 15 and the piston solenoids 22a, 22b, and 22c in a state where they are synchronized with each other. The vibration and the pipe line length of the trumpet 2 always maintain a resonance relationship, and a sound of air column resonance like a trumpet is produced.

  As described above, in this embodiment, the vibration waveform (musical signal waveform) to be actuated on the mouthpiece 21 (specific part) of the trumpet 2 is a method suitable for reproducing the vibration waveform on the mouthpiece 21 of the trumpet 2. Since the vibration waveform with the tempo and the pitch changed can be supplied to the vibration actuator 15, the degree of freedom of performance by automatic performance can be expanded. At this time, similarly to the tempo and pitch change for this musical tone signal waveform, the air column resonance can be maintained by appropriately changing the tempo and pitch for the fingering actuator data. The sound quality can be increased.

[Second Embodiment]
Next explained is the second embodiment of the invention.
FIG. 5 is a diagram showing a configuration of a musical instrument excitation device 200 according to the second embodiment of the present invention. The configuration of the instrument excitation device 200 is different from that of the instrument excitation device 1 according to the first embodiment in that a waveform memory type automatic sound generator performance data D11 and a waveform memory database DB1 are used instead of the drive waveform automatic performance data D1. The points stored in the storage unit 11, the point that a tempo / pitch change unit 214 is provided instead of the tempo / pitch change unit 14, and the point that the waveform memory type sound source unit 201 is provided.

The performance data includes a note code indicating the pitch, a sound generation interval (gate time) indicating the sound generation interval of the note, and velocity information indicating the loudness of one note. The waveform memory database DB1 stored in the storage unit 11 stores excitation waveforms corresponding to the single tone of the trumpet 2 for a plurality of scales. The excitation waveform stored in the waveform memory database is an excitation waveform recorded at a site where the vibration actuator 15 of the mouthpiece 21 is provided.

The tempo and pitch of the automatic performance data D11 are corrected. That is, for each note, the note code is changed corresponding to the changed pitch, and the gate time is changed according to the changed tempo.

The waveform memory type sound source unit 201 selects and reads a waveform of a pitch corresponding to the note code indicated by the performance data output from the tempo / pitch changing unit 214 from the waveform memory database DB1, and sets it to the length indicated by the gate time. It is processed so as to have a corresponding vibration waveform. At this time, the amplitude of the drive waveform is set according to the velocity indicated by the performance data. In this case, when the drive waveforms stored in the waveform memory database DB1 are not prepared for all the note codes, the waveform conversion pitch is changed to obtain a desired waveform.
The waveform memory type sound source unit 201 supplies the waveform data generated by processing the excitation waveform read from the waveform memory database DB1 as described above to the vibration actuator driving unit 16.

  The operation of this embodiment having the above-described configuration is as follows. The tempo / pitch changing unit 214 of the musical instrument excitation device 1 reads the waveform memory type sound source automatic performance data D11 from the storage unit 11. At this time, when the tempo or pitch is designated by the tempo designation unit 12 or the pitch designation unit 13, the tempo or pitch is changed according to the contents and supplied to the waveform memory type sound source unit 201. The waveform memory type sound source unit 201 generates an excitation waveform from the waveform memory database DB1 so as to obtain a vibration waveform corresponding to the note code, gate time, and velocity of each note indicated by the performance data supplied from the tempo / pitch changing unit 14. The waveform data read out and processed is supplied to the vibration actuator 15. On the other hand, the tempo / pitch changing unit 17 operates the fingering automatic performance data 11 read from the storage unit 11 with operation information obtained by changing the tempo and the pitch with the contents specified by the tempo specifying unit 12 or the pitch specifying unit 13. This is supplied to the actuator driving unit 18.

  The vibration actuator drive unit 16 drives the vibration actuator 15 according to the supplied waveform data. Further, the fingering actuator driving unit 18 drives the piston solenoids 22a, 22b, and 22c based on the operation information supplied from the tempo / pitch changing unit 17. At this time, the vibration actuator drive unit 16 and the fingering actuator drive unit 18 drive the vibration actuator 15 and the piston solenoids 22a, 22b, and 22c, respectively, in a synchronized state. Thereby, the vibration by the vibration actuator 15 and the pipe length of the trumpet 2 are always kept in a resonance relationship, and a sound of air column resonance like a trumpet is produced.

  Also in this embodiment, similar to the first embodiment, the vibration waveform (music signal waveform) to be actuated on the mouthpiece 21 (specific part) of the trumpet 2 is reproduced by the mouthpiece 21 of the trumpet 2. Since the vibration waveform with the tempo and the pitch changed can be supplied to the vibration actuator 15 of a method suitable for the above, it is possible to increase the degree of freedom of performance by automatic performance.

[Third Embodiment]
Next explained is the third embodiment of the invention.

The configuration of the instrument excitation device 300 is different from that of the instrument excitation device 1 according to the first embodiment in that instead of the drive waveform automatic performance data D1, physical model automatic sound source performance data D31 and sound source parameters P1 Are stored in the storage unit 11, a physical model method sound source unit 301 is provided, a tempo / pitch change unit 314 is provided instead of the tempo / pitch change unit 14, The components are the same as those of the instrument excitation device 1 according to the first embodiment.

  The physical model sound source automatic performance data D31 stored in the storage unit 11 is a collection of data for giving a sound generation instruction to the physical model method sound source unit 301 corresponding to the performance of the music. For example, in the case of a brass instrument, it is the breath pressure, the embouchure, the length of the tube, and the like. The sound source parameter P1 stored in the storage unit 11 is a parameter for designating the vibration waveform immediately below the mouthpiece 21 of the trumpet 2 as a physical model sound source. The physical model type sound source unit 301 realizes a physical model related to the sound generation of the trumpet 2 by data signal processing and supplies it to the vibration actuator driving unit 16. The physical model type sound source unit 301 corrects the performance data supplied from the tempo / pitch change unit 314 to the data corresponding to the sound source parameter P1, and supplies it to the vibration actuator drive unit 16.

  The tempo / pitch changing unit 314 reads the physical model type sound source automatic performance data D31 from the storage unit 11, and reads the physical model type sound source read according to the tempo and pitch specified by the pitch specifying unit 13 or the tempo specifying unit 12. The tempo and pitch of the automatic performance data D31 are corrected.

  Also in this embodiment, similar to the first embodiment, the vibration waveform (music signal waveform) to be actuated on the mouthpiece 21 (specific part) of the trumpet 2 is reproduced by the mouthpiece 21 of the trumpet 2. Since a vibration waveform with a changed tempo and pitch can be supplied to the vibration actuator 15 (sound source) of a method suitable for the above, it is possible to expand the degree of freedom of performance by automatic performance. At this time, the tempo and pitch are also changed with respect to the fingering actuator data. Since this is the same as in the second embodiment described above, the description thereof is omitted.
