However, in the case of a conventional string instrument (for example, others), in order to determine the fingering position of a user, a sensor is attached to a fingerboard including a plurality of strings and a fret, And so on.

This conventional method does not take into consideration the characteristics of a string instrument (for example, a guitar) generating a specific note by the length of the string formed by the contact between the string and the fret, The finger and the fret contact each other, but the finger does not touch the finger board, so that it is difficult to confirm the position of the fingertip accurately.

In addition, since existing string instruments (e.g., others) are embodied such that a plurality of strings are all laid over one saddle, a problem arises in that it is not possible to distinguish which vibrations occur in which strings. In order to solve this problem, even if a vibration sensor is connected to each string, vibration of a string is propagated through the saddle, so there is a limitation that accurate sensing is difficult due to interference between the vibration sensors.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

First, the performance control system of the present invention will be described with reference to FIG.

1, the performance control system 10 to which the present invention is applied includes a musical instrument 100 that generates notes related to performance based on at least one string and a fret, When a specific string and a particular prat associated with at least one specific note are selected through the input unit 100, the specific sensed value sensed by the specific vibration sensing sensor corresponding to the specific string, And a performance control device 200 for recognizing a specific sound based on position information confirmed by the fingering circuit.

The musical instrument 100 is a musical instrument that generates sounds related to performance based on a plurality of strings and frets. The musical instrument 100 includes a string having a length of a string formed by contact with a fret, (E.g., a guitar) that produces a specific note as much as possible. Hereinafter, for convenience of explanation, the musical instrument 100 will be described as being "other ".

The musical instrument 100 includes a fingerboard 110, a head 120, and a body 130.

The fingerboard 110 connects between the head 120 and the body 130 and includes a line group 111, a pratt group 112, and an LED group 113. For convenience of explanation, the line group 111 is composed of six strings L1 to L6, the pratt group 112 includes seven pratts F1 to F7, the LED group 113 is connected to the pratt F1- F7) is composed of six LEDs.

That is, the fingerboard 110 is provided with strings L1-L6 and pratts F1-F7, and displays finger positions at positions where the strings L1-L6 and the pratts F1-F7 cross each other The corresponding LEDs for the LEDs are arranged.

For example, when a user plays (exercises) by himself, when a specific LED among the LEDs on the finger board 110 becomes ON, the user confirms the fingering position based on the corresponding LED, It becomes possible to fingering a particular prefecture and a specific prat.

In the case of the musical instrument 100 having such a structure, when a user pushes a specific string among the strings L1-L6 for inputting a specific note, adjacent two pratts related to the particular string are simultaneously pressed and sensed .

This is due to the hardware structure of the musical instrument 100. Therefore, it is necessary to select the prat selected by the user from among two prunes, which may be sensed according to the pushing of the specific string, Strings, frets, and the like).

For example, when a user pushes a specific string L1 for input of a specific note and the two adjacent prunes F5 and F6 associated with the particular string L1 are sensed in contact with the strings, (F6) at a position closer to the first floor (130) is determined as the specific floor (F6).

That is, in the case of the plat F1-F7 of the present invention, the larger the plat number (1,2,3,4,5,6,7) of the plat F1-F7 is, the closer to the body 130 The prat F6 having a relatively higher plat number 6 than the prat F5 having the plat number 5 is pressed against the body (not shown) for the prats F5 and F6, 130, the prat F6 at a position closer to the body 130 will be selected as the specific prat F6.

This is because even if two pratts F5 and F6 related to the specific string L1 are sensed, the actual sound is the length of the string due to the fingertip of the prat F6 at a position closer to the body 130 An internal algorithm is applied in the present invention in which a prat F6 at a position closer to the body 130 is selected as a specific prat when two pratts are sensed so that a valid one prat position can be extracted .

In the specific region of the body 130, a current connection-related portion (or a high-rigidity portion) 131 for fixing the strings L 1 -L 6 connected from the head 120 and disposed on the fingerboard 110 Respectively. The current connection related portion 131 includes a saddle portion 1311 and a bridge portion 1312. [

Hereinafter, the saddle portion 1311 will be described in more detail.

The saddle portion 1311 includes at least one mini saddle SD1-SD6 having a number corresponding to the number of the strings L 1 -L 6 and supporting the strings L 1 -L 6.

2 shows an example of a saddle portion 1311 'provided on a body 130' of a conventional musical instrument 100 '. FIG. 3 shows an example of a saddle portion 1311' An example of the saddle portion 1311 is shown.

2, the saddle portion 1311 'provided in a specific region of the body 130' of the conventional musical instrument 100 'is formed of one saddle SD, (L1-L6) all extend over the saddle (SD).

That is, since all the strings L1-L6 are covered by one saddle SD, if the string vibration is sensed by the vibration sensor connected under the saddle SD when the user straps the string , And the vibration generated in the strings.

In order to solve this problem, even if a vibration sensor is connected to each of the strings L1-L6, the vibration between the strings L1-L6 propagates through the saddle SD, There is a limit point in which sensing is difficult.

3 (a), a saddle portion 1311 provided in a specific region of the body 130 is connected to at least one mini saddle (not shown) supporting the strings L1-L6 SD1-SD6).

That is, when mini saddles SD1-SD6 are generated by dividing one saddle SD into six numbers corresponding to the number of the current L1-L6, each mini saddle SD1- The saddle portion 1311 is formed in such a manner that the saddle portion 1311 is disposed at a position suitable for supporting the first through third lens groups L1-L6 with a predetermined blank region interposed therebetween.

At this time, the vibration detectors VS1 to VS6 are arranged in the corresponding number (six) in the corresponding holes H11 to H16 in which the mini saddles SD1 to SD6 are arranged, The corresponding vibration detection sensors VS1 to VS6 are connected to each of the mini saddles SD1 to SD6.

As a result, the saddle portion 1311 of the present invention generates mini saddles SD1-SD6 by the number (6) corresponding to the number of strings L1-L6, so that each string L1- SD6 to the saddle DS so that all the strings L1 to L6 are connected to the existing saddle DS by connecting the vibration sensing sensors VS1 to VS6 correspondingly to the respective mini saddles SD1 to SD6, The influence of the interference between the vibration sensing sensors that are generated due to the overloading can be minimized, and more accurate vibration sensing of each string (L1 to L6) can be performed.

On the other hand, when the mini saddles SD1-SD6 of the saddle portion 1311 are arranged with a predetermined blank area interposed therebetween as shown in FIG. 3A, There is a possibility that the mini saddles SD1-SD6 are separated and lost.

4A, a filling member 132 capable of absorbing shock and vibration is additionally disposed in a vacant area between mini saddles SD1-SD6, so that the saddle portion 1311 is integrally formed. . At this time, the filling member 132 does not have any limitation as long as it is a material capable of absorbing impacts and vibrations between the mini saddles SD1-SD6.

Alternatively, as shown in FIG. 4B, the saddle portion 1311 may be formed in a manner such that each mini saddle 1311 located in the second direction X, which is perpendicular to the first direction Y in which the strings L 1 -L 6 are arranged, The first filling member 133 is disposed such that all of the first sidewall SD1-SD6 of the first sidewall SD1-SD6 is brought into contact with all the sidewalls SD11, SD21, DS31, DS41, DS51, The second charging member 134 may be disposed so that all of the other surfaces SD12, SD22, DS32, DS42, DS52, and DS62 of the first charging member SD6 are brought into contact with each other.

Referring again to FIGS. 1 and 3, the bridge portion 1312 of the current connection-related portion 131 provided in a specific region of the body 130 will be described. Hereinafter, the mini saddles SD1-SD6 of the saddle portion will be described as being arranged with a predetermined blank region interposed therebetween as shown in FIG. 3 (a).

The bridge unit 1312 performs a function of sensing position information so that a fingering position of a specific note played by the user is determined.

More specifically, the bridge portion 1312 is disposed at a position adjacent to each of the mini saddles SD1-SD6 of the saddle portion 1311, and is connected to the corresponding string L1- L6 to enter and fix the inside of the body 130 to operate as a fingering circuit that enables determination of the fingering position of a specific sound.

2, in order to determine the fingering position of the user, a sensor is mounted on the fingerboard 110 'including the strings L1-L6 and the prisms F1-F7, And a method of judging whether or not to press.

This conventional method does not consider the characteristic of the musical instrument 100 'that generates a specific sound by the length of the string formed by the strings L1-L6 and the platters F1-F7, And the fingers F1-F7 are contacted but the finger contacts the fingerboard 110 'even if the finger L1-L6 and the platters F1-F7 are not in contact with each other, And there is a limit in that it is difficult to confirm the exact fingering position.

Accordingly, in the present invention, the bridge unit 1312, which operates as a fingering circuit and provides position information so that it can determine a fingering position of a specific sound, is implemented as follows.

The bridge portion 1312 includes at least one bridge pin 13121 for allowing each string L1-L6 to enter and fix the inside of the body 130 as shown in Fig. 5A, When each bridge pin 13121 is inserted into the corresponding bridge hole 13122 corresponding to each bridge pin 13121 after the corresponding string L1-L6 is connected to the pin 13121, And a power input member 1323 for supplying power to apply a specific voltage (3.3V).

Here, the power input member 1323 may be a copper plate for applying a specific voltage (3.3V) to the corresponding strings L1-L6 connected to the bridge pins 13121, And a voltage (3.3 V) is supplied. 5 (b), the power input member 1323 is disposed adjacent to the bridge hole 13122 and is inserted into the bridge hole 13122 so that the corresponding string L1 L6) to supply a specific voltage (3.3V) to the strings L1-L6.

Hereinafter, for the sake of convenience of explanation, the structure of the bridge portion 1312 which acts as a fingering circuit by referring to the string L1 as the specific string L1 selected by the user and the pratt F1 as the specific pratt F1 As will be described later.

5 (c), in the bridge portion 1312, the string L1 is hooked on the bridge pin 13121a corresponding to the specific string L1, the bridge pin 13121a is connected to the bridge hole 13122a, The end portion of the specific string L1 is fixedly caught by the bridge pin 13121a so that the specific string L1 caught by the bridge pin 13121a and the power input member 1323 come into contact with each other .

At this time, when a power source is connected to the power input member 1323 and a specific voltage (3.3V) is applied, the specific voltage (3.3V) applied to the power input member 1323 is transmitted to the specific string L1, A specific voltage (3.3 V) is also applied to the transistors L1 and L1.

When the specific plat F1 comes into contact with the user in a state in which the specific voltage (3.3 V) is applied to the specific string L1 according to the above-described manner, the bridge portion 1312 performs the operation ) To be able to perform the switch function, thereby sensing the position information.

6, the specific plat F1 is inserted into the corresponding plenum H21 formed on the fingerboard 110. At this time, the specific plat F1 protruding from the back of the printed circuit board (PCB) Is soldered to be able to act as part of the fingering circuit.

When a specific plat (F1) is connected to a PCB, a specific plat (F1) also acts as a part of the fingering circuit, and the user selects a particular string (L1) When the applied specific string L1 is brought into contact with the specific plat F1, data of the first voltage value (HIGH) can be read with respect to the specific plat F1 in the fingering circuit, The data of the second voltage value LOW can be sensed.

In other words, the fingering circuit of the present invention is formed by the specific string L1, the specific plat F1 and the bridge portion 1312. When the specific string L1 and the specific plat F1 are not in contact with each other When the specific string L1 and the specific pratt F1 come into contact with each other, the sensor is closed and the position information is sensed.

That is, when the specific string L1 to which the specific voltage (3.3V) is applied comes into contact with the specific pratt (F1) to become a closed circuit, the fingertip related circuit is configured such that the specific pratt (F1) The first voltage value HIGH is sensed by the first voltage value HIGH and the first voltage value HIGH is sensed by the first voltage value HIGH, So that the fingering position is confirmed.

As described above, in the present invention, the string L1-L6 and the prongs F1-F7 provided in the musical instrument 100 are connected to the bridge portion 1312 to operate as a fingering frame, L1-L6) and the pratt (F1-F7) are connected, it is not necessary to additionally include a separate sensor and connection line for performing the switch function. Therefore, the circuit configuration itself can be simplified, The overall sensing performance can be improved.

As described above, the musical instrument 100 will be described with reference to FIG. 1 again after the description of the musical instrument 100 is completed.

The performance control apparatus 200 may be configured to receive information (a specific sensing value, position information) sensed from the musical instrument 100 when a specific string and a specific prattle related to at least one specific note are selected through the musical instrument 100 To identify a specific note.

The performance control apparatus 200 includes a fingering position confirmation unit 210, a vibration confirmation unit 220, and a sound confirmation unit 230, as shown in FIG. Hereinafter, the specific string L1 and the specific pratt F1 mentioned above will be described in the same manner.

When the specific string L1 to which the specific voltage 3.3V is applied comes into contact with the specific pratt F1 and the fingers related circuit is closed, the fingertip position confirmation unit 210 determines that the voltage value of the prat F1- The corresponding pratt having the first voltage value HIGH different from the rest is determined as the specific pratt F1 and the fingertip position is confirmed.

That is, depending on the contact with the specific string L1 of the platters F1-F7 from the finger related circuit formed on the musical instrument 100, the plat F1 having the first voltage value HIGH is sensed The fingertip position confirmation unit 210 receives the positional information of the plat F1 from the fingertip related circuit and determines the received plat F1 as a specific plat F1 to confirm the fingertip position It will be possible.

The vibration confirmation unit 220 confirms the specific sensing value corresponding to the vibration of the specific string selected by the user.

That is, when the sensing value is received from the vibration sensing sensors VS1-VS6 connected to the respective mini saddles SD1-SD6 of the saddle portion 1311, the vibration confirmation unit 220 receives the sensing values VS1- VS6) detects a specific vibration sensor connected to a specific string based on the sensed value.

This is because the saddle portion 1311 mentioned above is divided into mini saddles SD1 to SD6 unlike the conventional ones and the vibration detecting sensors VS1 to VS6 are connected to correspond to each of the mini saddles SD1 to SD6, Since the influence of the interference between the sensors VS1 and VS6 is minimized, the vibration confirmation unit 220 identifies a vibration detection sensor that senses a corresponding sensed value that is equal to or greater than a threshold value among the sensed values received from the vibration detection sensors VS1 through VS6 And can be detected by a vibration detection sensor.

The vibration confirmation unit 220 may be a first state in which the sound is not generated in the musical instrument 100 based on the vibration characteristic information that is confirmed based on the sensing value for each of the vibration detection sensors VS1 to VS6, A second state in which a note is produced by hitting a specific portion (e.g., a body) of the specific string L1, and a third state in which the specific string L1 is distorted to generate a sound.

Here, the vibration characteristic information accumulates first vibration patterns having various sensing values for the vibration sensing sensors VS1-VS6 in the first state, and accumulates the first vibration patterns for the vibration sensing sensors VS1-VS6 in the second state. And may be a reference value that is generated by accumulating the second vibration pattern and accumulating the third vibration pattern having a different sensing value for each of the vibration sensing sensors VS1 to VS6 in the third state and is preferably generated and accumulated through various experiments something to do.

Accordingly, the vibration confirmation unit 220 compares the vibration characteristic information, which is confirmed based on the sensing value for each of the vibration sensing sensors VS1 to VS6, with the first to third vibration patterns, and determines a specific vibration pattern to be most closely matched (First state / second state / third state) corresponding to a specific vibration pattern when the degree of matching between the vibration characteristic information and the specific vibration pattern falls within a predetermined threshold range.

In the embodiment of the present invention, the first to third states are distinguished based on the vibration characteristic information. However, the present invention is not limited to this, and it is possible to identify the vibration pattern according to the combination of the first to third states, It is needless to say that the mixing state occurring at the same time can also be distinguished.

The sound confirmation unit 230 confirms a specific sound played by the user based on the specific sensing value received from the vibration confirmation unit 220 and the fingering position confirmed by the fingering position confirmation unit 210. [

As described above, according to the present invention, by optimizing the performance of a string instrument (e.g., a guitar), sound related information (e.g., strings, frets, Etc.) to be sensed more precisely, resulting in a new performance device hardware implementation scheme being realized.
