Embodiments of the present invention will be described below with reference to the drawings. Hereinafter, a case where the present invention is applied to an electric violin will be described as an example. Such an embodiment shows one aspect of the present invention, and does not limit the present invention, and can be arbitrarily changed within the scope of the present invention.

A: Configuration of Embodiment FIG. 1 is a block diagram showing the overall configuration of an electric violin according to a first embodiment of the present invention. As shown in the figure, this electric violin is composed of a bow (drive member) 1, a violin main body 2, DSPs (Digital Signal Processors) 3 and 4, a vibration signal processing unit 5, a storage unit 6, an amplifier 7, and a speaker 8. Have been. Then, the player of the electric violin performs the performance by rubbing the strings 23 of the violin body 2 with the bow 1 in the same manner as the violin of a normal natural musical instrument (hereinafter referred to as “natural violin”).

FIG. 2A is a plan view showing the configuration of the electric violin bow 1 according to the present embodiment. As shown in the figure, the bow 1 functions as a driving member for applying vibration to a string 23 of the electric violin body 2 which is a sound source, and includes a bow body 11, a bow hair 12, and a frog ( (Hair box) 13. A frog 13 having a substantially rectangular parallelepiped shape is fixed to one end of the bow body 11, and a bow hair 12 is given tension between the bow tip 14, which is the other end of the bow body 11, and the frog 13. It is configured to be supported in the state in which The above configuration is the same as the configuration of the natural violin bow, but the electric violin bow 1 according to the present embodiment includes a bow-side pickup 10 (drive member-side signal generating means) in addition to these components. It has become.

Here, FIG. 2B is an enlarged view of the vicinity of the above-described frog 13 in the bow 1 shown in FIG. 2A. As shown in FIG. 2B, the bow 1 according to the present embodiment has a configuration in which the bow-side pickup 10 is mounted on a side surface of the frog 13 and near the bow hair 12. The bow-side pickup 10 is, for example, an acceleration pickup constituted by a piezoelectric element. Then, the vibration of the bow hair 12 generated when the player rubs the string 23 stretched on the violin main body 2 with the bow 1 propagates to reach the bow-side pickup 10 and the vibration signal (electrical signal) Hereinafter, this will be referred to as “bow-side vibration signal”). It should be noted that the bow-side pickup 10 only needs to be able to generate a vibration signal corresponding to the vibration generated in the bow, and in addition to the above-described acceleration pickup, for example, a pickup for detecting speed or displacement, a force for detecting force, and the like. A gauge or the like can also be used.

Next, FIG. 3A is a plan view showing the appearance of the electric violin main body 2 according to this embodiment. As shown in the figure, the electric violin main body 2 includes a sound box 21 which is a hollow box, a neck 22 fixed to the sound box 21 in a posture extending from the sound box 21, and four strings ( Pronunciation source) 2
And 3. A bobbin 24 provided in the vicinity of the tip of the neck 22 and an buckle plate 26 fixed to a front plate 25 constituting the sound cylinder 21 support these four strings 23 under tension. are doing. Further, a piece 27 is sandwiched between the front plate 25 and the string 23 constituting the sound cylinder 21, so that the vibration generated in the string 23 is transmitted to the sound cylinder 21 via the piece 27. It has become. The vibration transmitted in this way causes resonance in the sound cylinder 21.

FIG. 3B is an enlarged view of the vicinity of the piece 27 when the electric violin body 2 shown in FIG. 3A is viewed from the direction of arrow A in FIG. As shown in FIG. 3 (b), the electric violin main body 2 is
The main body side pickup 20 is positioned at a position where the upper piece 27 contacts.
Is buried. The main body side pickup 20 is an acceleration pickup similar to the bow side pickup 10 described above, receives vibration transmitted from the string 23 via the piece 27 and vibration caused by resonance of the sound cylinder 21, and responds to this vibration. A vibration signal (hereinafter, referred to as “main body side vibration signal”) is output. The position where the main body side pickup 20 is incorporated into the electric violin main body 2 is not limited to the position shown in FIG. For example, it may be arranged at a position in contact with the neck 22 and the sound cylinder 21 and detect the vibration transmitted from the string 23 to each of these parts via the piece 27.

In this embodiment, as will be described later, the DSP 3 adds a frequency characteristic of a natural violin sounding body to the main body side vibration signal. Accordingly, the electric violin sound cylinder 21 according to the present embodiment does not need to have the same frequency characteristics as the natural violin sound cylinder, and thus has a configuration (for example, small in size) different from the natural violin sound cylinder. Is also good. In this case, of course, a musical tone can be output at a relatively low volume by the instrument body without operating the pickup-electroacoustic system.

Returning to FIG. 1 again, the DSP 3 responds to the main body side vibration signal output from the main body side pickup 20.
The calculation represented by the equation in FIG. 1 is performed. In particular,
The DSP 3 simulates a virtual torso, which is a sounding body of a natural violin, by performing such calculations. That is, while canceling the frequency characteristic from the main body-side vibration signal accompanied by the frequency characteristic of the real body (sound cylinder 21) obtained via the main body pickup 20, the frequency of the virtual body, which is an arbitrary natural violin sound body, The main body-side vibration signal to which only the characteristic is given is generated and output.
Here, in the arithmetic expression shown in FIG.
rted Filter) represents the reciprocal of the transfer function of the real or virtual torso.

As shown by the broken line a in FIG. 1, whether the main body side vibration signal output from the main body side pickup 20 is output to the DSP 3 in response to an instruction from the user,
Output directly to the vibration signal processing unit 5 or DSP3
And output to both the vibration signal processing unit 5 may be selected.

The DSP 4 performs a predetermined operation on the main body side vibration signal output from the DSP 3 to simulate an arbitrary sound field. That is, for example, the DSP 4 responds to the concert hall,
The sound field characteristics of a church or live house are added and output. In addition, as indicated by a broken line b in FIG. 1, in response to an instruction from the user, the main body side vibration signal output from the DSP 3 is output to the DSP 4, the vibration signal processing unit 5, or the DSP 4 And output to both the vibration signal processing unit 5 may be selected. FIG.
As shown by the broken lines a and b in the middle, when the signal supplied to the vibration signal processing unit 5 can be selectively switched in accordance with an instruction from the user, various signals can be selected according to each user's preference. Since it can output musical tones of tones,
There is an advantage that more diverse performances can be enjoyed.

The vibration signal processing section 5 mixes and supplies the supplied bow-side vibration signal and main-body-side vibration signal.
Here, the vibration signal processing unit 5 can change the mixing ratio between the bow-side vibration signal and the main-body-side vibration signal according to an instruction from the user. Therefore, the user can select and output only one of the bow-side vibration signal and the main-body-side vibration signal. further,
The vibration signal processing section 5 can write either or both signal waveforms of the bow-side vibration signal and the main-body-side vibration signal into the storage section 6 according to an instruction from the user.

The amplifier 7 amplifies and outputs the output signal of the vibration signal processing unit 5. The signal amplified by the amplifier 7 is output from the speaker 8. Note that a configuration in which headphones are provided instead of the speaker 8 shown in FIG. 3 may be employed. The above is the configuration of the electric violin according to the present embodiment.

B: Operation of Embodiment Next, the operation of the electric violin according to the embodiment will be described. First, when the player bows the string 23 using the bow 1, the string 23 vibrates with this bowing operation. This string 2
The vibration generated in 3 is transmitted to the sound cylinder 21 via the piece 27, and the vibration causes the resonance of the sound cylinder 21. As a result, vibration of the string 23 transmitted through the bridge 27 and vibration due to resonance of the sound cylinder 21 are generated on the front plate of the sound cylinder 21. The main body side pickup 20 detects such vibrations generated on the front plate 25, generates a main body side vibration signal which is an electric signal similar to the waveform of these vibrations, and
Output to 3. The resonance of the sound cylinder 21 causes a musical sound to be radiated, and the radiated sound can be muted by a volume control device (not shown).

The DSP 3 performs an operation represented by the equation in the figure on the supplied main body side vibration signal and outputs the result. As described above, this calculation cancels the frequency characteristics of the sounding body 21 (real body) of the electric violin main body 2 included in the main body side vibration signal, and adds the natural violin sounding body (virtual body) to the main body side vibration signal. Is given.
By doing so, the musical sound output from the speaker 8 based on the main body side vibration signal can be approximated to the musical sound of a natural violin.

The DSP 4 adds a preset sound field characteristic to the main body side vibration signal output from the DSP 3 and outputs the signal to the vibration signal processing unit 5.

On the other hand, with the above-described stringing operation,
The bow hairs 12 stretched on the bow 1 also vibrate. Then, the bow-side pickup 10 generates a bow-side vibration signal, which is an electric signal similar to the waveform of the vibration, and outputs the generated signal to the vibration signal processing unit 5. By this, the same pitch (pitch feeling) as the string vibration
Is obtained.

The vibration signal processing unit 5 includes the bow pickup 1
The bow-side vibration signal supplied from 0 and the main-body-side vibration signal supplied from the DSP 4 are mixed at a mixing ratio designated by the user and output. When the main body side vibration signal is also supplied from the main body side pickup 20 or the DSP 3 as shown by the dashed line a and the dashed line b in FIG. Side vibration signal and main body side pickup 2
0, a main body-side vibration signal supplied from the DSP 3 and the DSP 4 are mixed and output.

Here, when the user operates an operation unit (such as a switch) (not shown) to give an instruction to store the vibration waveform, the vibration signal processing unit 5 The temporal change of one or both of the vibration signal and the main body-side vibration signal is sequentially written in the storage unit 6.

The output signal from the vibration signal processing unit 5 is
The signal is amplified by the amplifier 7 and output from the speaker 8. Since the bow-side vibration signal and the main-body-side vibration signal are signals having substantially the same pitch, the musical tone output by mixing these is composed of a musical tone by the bow-side vibration signal and a musical tone by the main-body-side vibration signal. The sound is mixed without discomfort. The above is the operation of the electric violin according to the present embodiment.

In the operation described above, the vibration generated in the string 23 causes the resonance of the sound cylinder 21 via the piece 27, so that filtering is performed. Accordingly, the musical tone output based on the main body side vibration signal output by the main body side pickup 20 is a musical tone having a relatively gentle attack portion with a reduced amount of higher harmonic components. On the other hand, the bow-side vibration signal output by the bow-side pickup 10 is not subjected to such filtering. Therefore, the musical tone output based on the bow-side vibration signal contains richer harmonic components and has a sharp attack portion, as compared to the musical tone output based on the main-body-side vibration signal described above. It becomes a musical tone.

As described above, according to the electric violin according to the present embodiment, the performance can be performed using the vibration signal generated in the bow 1 in addition to the vibration generated in the string 23. Therefore, rich performance expression can be realized as compared with a case where only a musical tone based on a main body side vibration signal is output like a conventional electric violin.

Further, since the mixing ratio between the bow-side vibration signal and the main-body-side vibration signal can be arbitrarily adjusted, it is possible to output a musical tone that suits each user's preference.

Furthermore, the performance can be evaluated by subjecting the waveform of the vibration signal stored in the storage section 6 to, for example, FFT analysis. In particular, the bow-side vibration signal is
As compared with the main body side vibration signal which is filtered by the above-mentioned method, the delicate operation of the player is easily reflected. Therefore, by analyzing the bow-side vibration signal, it is possible to perform an accurate evaluation of the performance, particularly an evaluation relating to the bowing operation.

In the above embodiment, the configuration is such that the waveform of the vibration signal is written in the storage unit. However, the present invention is not limited to this. For example, only the pitch (pitch) of the vibration signal is detected.
A configuration for writing to the storage unit 6 may be adopted.

C: Modifications Although one embodiment of the present invention has been described above, the above embodiment is merely an example, and various modifications may be made to the above embodiment without departing from the spirit of the present invention. be able to. For example, the following modifications can be considered.

<Modification 1> In the above embodiment, the case where the present invention is applied to an electric violin has been described as an example. However, the present invention is not limited to this, and a musical instrument that vibrates a string using a bow, for example, a viola, a cello Alternatively, it may be a contrabass or the like.

Further, the present invention is not limited to the application of a musical instrument which generates a musical tone by vibrating a string using a bow, and the sound source is driven by using any driving member. If it is a musical instrument that generates musical sounds,
It can be applied to any musical instrument. For example, when applied to a drum that vibrates by striking a pad (sound source) with a stick (drive member),
In addition to the musical sound caused by the vibration of the pad, the vibration of the stick may be detected and the musical sound corresponding to the vibration may be output. Similarly, when the present invention is applied to a saxophone, a clarinet, or the like that vibrates a mouthpiece (sound source) by a lead (drive member), the vibration of the reed is detected in addition to the musical sound caused by the vibration applied to the mouthpiece. Then, a configuration may be adopted in which a musical tone corresponding to the detected vibration is output.

As described above, the “driving member” in the claims is a concept including various means for giving vibration to a member that generates a musical sound, such as a bow, a stick, and a lead. Is a concept including various members driven by the driving member, such as the strings, pads, and mouthpieces described above.

<Modification 2> In the above embodiment, the vibration signals output from the bow-side pickup 10 and the main-body-side pickup 20 are mixed and output in the vibration signal processing unit 5, but the present invention is not limited to this. From at least one of these vibration signals, a MIDI signal related to pitch and volume may be generated and output to an electronic sound source to generate a musical tone. In this case, the vibration signal processing unit 5 includes the bow-side pickup 10,
The outputs of the main body side pickup 20 and the electronic sound source may be mixed at an arbitrary mixing ratio.

The following configuration may be adopted. For example, an actuator for converting an electric signal into vibration is provided on a box having a shape similar to a sound body of a natural violin, and this actuator, the bow pickup 10 and the main body pickup 20 are connected by any signal line. Connecting. Then, one or both of the vibration signals output from the bow-side pickup and the main-body-side pickup are transmitted to the actuator via this signal line. In this way, if a vibration similar to the vibration generated in the bow or the string is given to the above-described box,
Musical sound is generated by the resonance of the box caused by this vibration. By doing so, it is possible to perform the performance by arranging the bow or string on which the player performs and the box in which the musical tone is generated at a physically separated position, thereby performing various performance modes. Can be realized. That is, it is possible to provide a violin sound drum type electric musical sound converter.

<Modification 3> In the above embodiment, the vibration signal processing section 5 mixes the bow vibration signal output from the bow pickup 10 and the main vibration signal output from the main pickup 20. However, the present invention is not limited to this. For example, two speakers are provided,
A configuration may be adopted in which a tone corresponding to the bow-side vibration signal is output from one speaker, and a tone corresponding to the body-side vibration signal is output from the other speaker. Further, at this time, for example, as in the second modification, the pitch may be detected from the bow-side vibration signal, a desired electronic sound source corresponding to the pitch may be driven, and the musical tone may be output from the speaker.

<Modification 4> In the above embodiment, the electric violin main body is provided with a sounding body different from the sounding body of the natural violin, and resonates in the sounding body when vibration from the strings is transmitted. However, the present invention is not limited to this, and the electric violin body may be configured as shown in FIG. 4, for example. In addition,
In FIG. 4, the same parts as those in FIG. 2 described above are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 4, the electric violin main body 2 'in the present modification does not have the sound box 21 which is a hollow box like the electric violin main body in the above embodiment, but has a neck 22 and a stop plate. 26 has a plate-shaped body portion 28 for supporting the same. On one side of the body 28, a plate-like member having the shape of a natural violin sounding body is provided in design, and on the other side of this plate-like member, the user holds the jaw when playing. A chin pad 29 (not shown in FIG. 3 (a)) for supporting the chin is provided.

With such a configuration, unlike the natural violin and the electric violin in the above embodiment, resonance of the sound cylinder does not occur, so that the main body side vibration signal output from the main body side pickup includes The frequency characteristics of the sound cylinder are not added as in the embodiment. Therefore, in the above embodiment, the frequency characteristics of the body are canceled to provide the frequency characteristics of the resonance body of the natural violin.However, in this modification, it is not necessary to cancel the frequency characteristics of the body. What is necessary is just to add the frequency characteristic of a natural violin. Even in this case, the same effect as in the above embodiment can be obtained.

Further, the sound cylinder of the electric violin may be the same as the sound cylinder of the natural violin. In this case,
Since it is not necessary to approximate the tone generated by the main body side vibration signal to the tone of a natural violin, the DSP
3 becomes unnecessary.

<Modification 5> In the above embodiment, the bow-side vibration signal output from the bow-side pickup 10 and the body-side vibration signal output from the body-side pickup 20 are mixed and output. However, the present invention is not limited to this. For example, modulation such as amplitude modulation may be performed on the main body side vibration signal output from the main body side pickup 20 using the bow side vibration signal output from the bow side pickup 10. By doing so, it is possible to impart the characteristic of the musical tone by the bow-side vibration signal to the musical tone by the main-body-side vibration signal, so that a more diverse performance can be realized.

<Modification 6> In the above embodiment, as shown in FIG. 2B, the bow-side pickup 10 is provided on the side surface of the frog 13 at a position near the bow hair 12. The position where the bow-side pickup 10 is provided is not limited to this position. For example, a bow-side pickup 10 may be provided at a portion where a player grips his hand when performing a bowing operation using the bow 1. In this way, the bow-side vibration signal output by the bow-side pickup 10 changes depending on how the player holds the bow 1, so that more diverse performance expressions are possible.

<Modification 7> In the above embodiment, the mixing ratio in the mixing by the vibration signal processing unit 5 can be set arbitrarily by the user, but the mixing ratio may be a fixed value. In this case, for example,
Mixing ratio of bow side vibration signal and main body side vibration signal is 1: 4
With this setting, a bright and exciting tone can be obtained.

[0053]

As described above, according to the present invention,
In addition to vibration signals generated on the strings and filtered by resonance in the pieces and the torso, it can be played using vibration signals corresponding to vibrations generated on the bow, so it is richer than conventional electric violins It is possible to realize a great performance expression. In addition, various information that has not been used in a conventional electric musical instrument, that is, information on a playing style or the like can be acquired and used for performance.
