Description

Combination of Bass and Treble material is different from other combinations. {COMBINATION NUT FOR DIFFERENT LOW AND HIGH SOUND MATERIAL}

The present invention relates to a guitar set-up device capable of setting a guitar by varying the line height of a guitar. More specifically, the present invention relates to a guitar set-up device for adjusting a height of a saddle by adjusting the height of a saddle, The present invention relates to a combination present state of an electric guitar capable of simultaneously performing the same.

Since the neck of the electric guitar is made of wood, it shrinks and expands as the external environment changes. That is, the shape of the neck (degree of warp) can be changed from time to time by ambient temperature and humidity, and also by the tension of the string or the force applied when it is leaned against the stand and wall. Since the neck is not rigidly fixed, it vibrates along with the string and is sensitive to small forces. Therefore, the guitarist who plays the guitar should be able to adjust each component of the guitar (neck, string, Etc.). This is called a setup of the guitar.

Other set-ups typically include a neck adjustment step through a truss rod, a height adjustment of the saddle through the vertical thread of the saddle, a pitch and intonation adjustment step through the horizontal thread of the saddle, And adjusting the height of the pickup. In general, the height adjustment step of the saddle is performed for convenience of playing and elimination of buzz regardless of the pitch or pitch of the line. On the other hand, the pitch adjustment step adjusts the length of the line so that the player can accurately express the target pitch or pitch.

A violin-free stringed instrument can produce accurate intonation (pitch) while changing the position of the fingertip. However, in the case of a stringed instrument with a platter like a guitar, the position of the pratt is fixed (in the pitch adjustment step) It is common to adjust the intonation. The pitch adjustment step first adjusts the length of the string by adjusting the pitch of the open string through the tuner and comparing the pitch of this open string with the pitch of the 12th pratt (one octave higher). In other words, the player picks up the fingers between the 11th pratt and the 12th prat with his fingers and compares the sound between the 12th pratt and the birds to the open sound.

However, it is very difficult to adjust the harmonics of the entire line even if you are going through these pitch adjustment steps. That is, even if the setup is completed through all of the pitch adjustment steps, precise set-up is not performed on all the pratts. That is, even if pitch adjustment is performed on the basis of the 12th pratt, no other sound is produced on the other pratt in addition to the 12th pratt. This exact tone adjustment occurs as a very minor difference, and in the past, a skilled professional had to adjust the guitar's height and pitch separately, while listening directly to the ear. This is a set-up that depends on personal experience and intuition and adjusts the harmonious sound distribution of the entire line through fine tuning that can not be captured by a general tuning machine.

However, since all the performers can not receive the settings of the experts each time they play, there are other setup devices that allow the general public to easily follow the fine settings individually performed by the experts depending on experience and intuition Is required.

It is an object of the present invention to make it possible for a general person to perform precise other setups at a professional level.

The front sound of the Pratt (the sound between the nut and the nth Pratt - the first sound) when the nth Pratt and the n + 1 Pratt are picked up is the backward note (n + 1) The second note). This is because even if a single string is separated into pratt and only a part of it is used to play the sound, the interplay of the front and back strings affects the entire string.

The other set-up device according to the present invention uses this principle, and when picking up between one of the n rows of the other rows and the row n + 1 of the other row, the first set- and the saddle height of the line is changed based on the difference of the second note between the n + 1-th pratt and the saddle.

More specifically, the guitar setup apparatus according to the present invention includes: a sound receiving unit for independently receiving a first note between a nut and an nth prune, and a second note between a n + 1 prat and a saddle; A tone comparator for comparing the first tone and the second tone; And a saddle height determination unit for determining a saddle height change value of the corresponding line based on a comparison result of the sound comparing unit.

Here, the guitar is an electronic guitar having 6 lines, the n-th pratt is 11 pratt, the n + 1 pratt is 12 pratt, and the sound receiving unit is a pickup. More specifically, the sound receiving unit includes a first sound receiving unit between the nut and the nth prune, and a second sound receiving unit between the n + 1 prat and the saddle. Here, the first sound receiving unit is attached to the neck, and the second sound receiving unit is attached to the body.

Alternatively, the sound receiving unit may be attached to the head and receive the first sound and / or the second sound by vibrations, respectively.

The sound comparator compares the difference in height or waveform of the first and second sounds.

More specifically, the other setup device according to the present invention further includes a storage unit for storing thread information of a saddle height adjusting screw provided on the guitar, wherein the saddle height determining unit divides a saddle height change value by the thread information And determining the screw rotation value. The display unit may further include a display unit for visually indicating a change value of the saddle height and the screw rotation value.

Another object of the present invention is to provide a guitar setup method for setting guitar line height through the guitar setup device, comprising: picking up between one of the plurality of guitar rows of the n th and the n + 1 th rows; Placing a first note between the nut and the nth prune and a second note between the n + 1 prat and the saddle; Receiving each of the first and second sounds separately through a sound receiving unit; Comparing the first tone with the second tone through a tone comparator; And a step of determining a change value of the saddle height of the corresponding line based on the comparison result of the sound comparing unit through the saddle height determining unit.

According to the present invention, an ordinary person can set up a micro level guitar setup only by fingering the n th and (n + 1) th prats with a finger.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Also, in order to clearly illustrate the present invention in the drawings, portions not related to the present invention are omitted, and the same or similar reference numerals denote the same or similar components.

The objects and effects of the present invention can be understood or clarified naturally by the following description, and the purpose and effect of the present invention are not limited by the following description.

The objects, features and advantages of the present invention will become more apparent from the following detailed description. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

1 is a front view of a general guitar 200. FIG.

Although the present invention can be applied to all guitars using strings, an electronic guitar, especially a panda strucocaster model, is used in this embodiment. However, the invention applies to all guitars having saddles 2311, but is not limited to any particular type of body 230 (body).

The guitar 200 shown in FIG. 1 is largely divided into a head 210, a neck 220, and a body 230.

The head 210 is provided with a tether 213 and a peg which are fixed to the tether 210 to adjust the tension of the tether through rotation. Preferably, a string guide 215 is provided on the head to maintain the string tension.

The neck 220 is provided with a finger board 221 and a finger is used to push the string above the fingerboard 221. A plurality of metal pratts 223 (Fret) are positioned on the fingerboard 221, and a string pressed on the fingerboard is placed on the pratt to determine the pitch. Electronic guitars typically have 21 or 22 pratts, and fewer but 24 pratts can be used. The nut (221), or Nut, plays the role of supporting the neck of the neck, and makes it possible to produce an open tone when making sounds without holding the prat.

The body 230 is provided with a bridge 231 for connecting a guitar string to a body and a saddle 2311 is mounted on the bridge 231 to adjust the string height. The bridge 231 is provided with a saddle vertical screw 2313 and a horizontal screw 2315 to adjust the height of the saddle through the vertical screw 2313 through the horizontal screw 2315 do. A pickup 233 converts the vibration of the string into an electrical signal and transmits it to an amplifier (not shown) located outside or inside via a jack 235 (Jack).

There are various types of the bridges 231 according to other types and applications. For example, there are synchronized bridge (vintage bridge), two point synchronized bridge, fixed bridge, Wilkinson bridge, tuneomatic bridge, Floyd Rose bridge, ropeway edge bridge, spring slob bridge, tele bridge. The present invention is characterized in that the height of the saddle is adjusted. The present invention can be applied to all of the above-mentioned bridges which can change the height of the saddle although there is a difference in the height changing method. Preferably, however, a bridge (e.g., a synchronized bridge) capable of adjusting the line height for each string is preferred. Hereinafter, the bridges of the embodiments shown in FIGS. 3 to 5 will be described with the assumption that each line is a bridge capable of adjusting the line height.

The present invention is characterized in that the nut 221 and the 11th pratt 2211 are arranged between the n th prat 2231 and the n th prat 2232, And adjusting the pitch of the strings by adjusting the pitch of the strings using the relationship between the pitch (first pitch) between the first pitch and the saddle 2311 and the second pitch between the twelfth pitch and the saddle 2311. In more detail, the setup and pitch control are performed using the difference between the pitch of the first note and the pitch of the second note.

The guitar has a structure that goes up by one semitone for each fret. In other words, if the pitch is 5 when A is tuned to A = 440hz and the pitch is A when the 5th line is tuned to open, then when you hear 12th prune on line 5, it is exactly one octave higher. Mathematically, one octave higher is produced at half the length of the line. In practice, however, when the rope touches the prat, it is pressed down to the distance from the rope height to the fingerboard, so that the length of the string becomes longer and the tension increases accordingly, so that the saddle is positioned further backwards than the actual mathematically half- (See the pitch and intonation adjustment steps described above).

Generally, the guitar sound that the audience listens to is the playing sound to enter the pickup, that is, the second sound, but the guitar line is a connected extension line. The first sound does not enter the audience into the ear but is closely related to the second sound. That is, in order to accurately adjust the sound quality of the second sound, the first sound must be referred to. Thus, the present invention is intended to realize a harmonious sound distribution over a line through a comparison between a second sound heard in the ear and a first sound not audible to the ear in one row.

According to a preferred embodiment of the present invention shown in FIGS. 2 and 3, first, the nuts 221 are picked up between the 11th and 12th prongs of one of the other plurality of rows (row 5 in FIG. 3) And the second sound between the first prong 2232 and the saddle 2311. The second sound is generated between the first prong 2232 and the saddle 2311, As a method for picking up other ropes, a method of picking up the rope of the corresponding prat with a finger onto the fingerboard (Fig. 2) is preferable, but a device such as Capo which mechanically picks up a specific prat may be used. As the first and second tone generating methods, it is preferable to use a hamming method (a method of striking the finger between the 11th prince and 12th prince with the fingers).

According to a preferred embodiment of the present invention, in order to receive the first and second sounds, the sound receiving unit 110 may include a tuner for grasping sound properties (for example, frequency) through vibrations transmitted through a conventional neck, The vibrations of the first sound and the second sound transmitted through the neck may be detected by being attached to the head 210 as well. In this case, the sound receiving unit for sensing the vibration can use a known technique of attaching the sound receiving unit to the other head portion to recognize the sound vibration. However, since the first and second vibrations may interfere with each other when the vibrations are simultaneously inputted, it is preferable that the first and second sounds are independently emitted. Thus, in the present embodiment in which the sound receiving unit 110 is attached to the head 210, instead of the hammering method, the first sound and the second sound are made to sound with a finger at the 12th prong, It is preferable to issue a sound and a second sound. At this time, whether the sound (vibration) received in the future through the setting unit (not shown) is set in advance so as to specify the first and second notes inputted at a time difference It is also good.

According to another embodiment of the present invention, when the above-described hammering method or the first and second notes are generated at the same time, the first note may not be audible unlike the second note that is amplified by being received in the pickup It is preferable that a separate sound receiving unit 113 for only receiving the first sound is located in the neck 220 between the nut 221 and the 11th prune (see FIG. 7). Also, while holding the finger between the 11th prin and the 12th prin with the fingers, the other fingers sequentially repel between the nut (221) and the 11th pratt and the 12th pratt and the saddle (2311) to produce the first and second notes There can be a way.

Although the present invention can be applied to any of a plurality of guitar strings, the effect of the present invention can be most notably felt in the sixth string (the thickest string) having the strongest tension. This is because the tension of the sixth line is strongest when the first and second sounds are not harmonized.

Hereinafter, the other setup device 100 according to the present invention will be described with reference to FIG. The other setup apparatus 100 according to the present invention includes at least one sound receiving unit 110, a sound comparing unit 120, and a saddle height determining unit 130.

According to a preferred embodiment, the present invention may include one or more sound receiving units (110, 111, 113) capable of independently receiving the first sound and the second sound, respectively. The sound receiving unit is preferably a pickup. However, the sound receiving unit includes all sound sensor means such as a general microphone, which can change the vibration of the air into an electronic signal. Preferably, the sound receiving unit receiving the second sound may transmit the second sound information to the other set-up apparatus 100 according to the present invention through the jack 235 as a pickup 111 and 233 provided in the body 7). As described above, when the first note and the second note are simultaneously sounded through the hammering key method, the second note can be originally received through the pickup 111 and 233 provided in the body, but in the case of the first note It is preferable that a separate sound receiving unit 113 is placed between the nut 221 and the n-th prune 2231 so that the first sound having a relatively small volume can be received.

The sound comparator 120 compares the properties of the first and second sounds received by the sound receiver. The negative nature is preferably a frequency (pitch) or a waveform (tone). According to a preferred embodiment of the present invention, when comparing the properties of the first and second sounds at a frequency (Hz), the sound receiving unit 110 first converts the negative frequency into an electric signal and transmits the electric signal to the sound receiving unit. Then, the most representative frequency (for example, the frequency with the largest magnitude or the frequency with the largest magnitude frequency component) is determined as the representative frequency of the sound from the electric signal. More preferably, the frequency components other than the representative frequency are analyzed and determined as the peripheral frequency. According to another preferred embodiment of the present invention, a negative waveform is determined by changing the electric signal transmitted from the sound receiving unit to a time function or a frequency function (see FIGS. 8 and 9).

The following is theoretically the exact frequency (theoretical frequency) of the note when A = 440 Hz.

(Line 1) F5 = 698.456hz

(Line 2) C4 = 523.258hz

(Line 3) Ab4 = 415.305hz

(Line 4) Eb4 = 311.127hz

(Line 5) Bb3 = 233.082hz

(Line 6) F3 = 174.614hz

The following shows the frequency distribution of the first and second sounds when n = 11, n + 1 = 12 and A = 440 Hz.

First note in line 1: F5 '= 700.044Hz / Second note: E5 = 659.255hz

First note in line 2: C4 '= 526.818hz / second note: B4 = 493.883hz

First note in line 3: Ab4 '= 420.968hz / second note: G4 = 391.995Hz

First note in line 4: Eb4 '= 314.663hz / second note: D4 = 293.665hz

First note in line 5: Bb3 '= 236.260hz / second note: A3 = 220.000Hz

First note on line 6: F3 '= 177.789hz / second note: E3 = 164.814hz

As described above, since the guitar differs in semitone by one per flat, the first sound and the second sound are related to each other by a difference of semitones (only two degrees). That is, the second note is lower in semitone than the first note. Here, the second note (played sound, the sound between the 12th pratt and the saddle) is now correctly tuned to A = 440Hz. If the second note is correctly tuned to the original 440Hz reference, the first note (note between the nut and the 11th prune) should be exactly one semitone lower and only two degrees relative. However, as can be seen from the theoretical comparison with the frequency, it can be seen that virtually every line does not have the expected odd-degree relationship. Theoretically, the first note should be Bb3 = 233.082hz, but actually Bb3 '= 236.260hz, which is 23.44 cents, since the second note in row 5 is exactly A3 = 220.000Hz (half of A4 = 440.000hz) ). In particular, it can be seen that the difference (31.19 cents) is the highest in line 6, which has the strongest tension.

The saddle height determination unit 130 determines a change value of the saddle height of the corresponding line based on the comparison result of the sound comparing unit. Generally, the height of the line is determined by the height of the saddle. Generally, since the height between the six lines changes according to the curvature of the fingerboard, the line height is set higher for the sixth line (thick line), and the line height is set lower for the first line (thin line). That is, although the fingerboard has a flat fingerboard (generally, a flat fingerboard), the finger has generally a radius, and the height of the saddle for each of the lines is also adjusted to correspond to the curvature. Although the curvature differs from one manufacturer to the other, according to a preferred embodiment of the present invention, the radius of curvature has a curvature of 24.1 cm (9.5 inches) or 18.4 cm (7.25 inches) on the basis of a Panther Stradocaster.

In the past, the height of the saddle has been focused on the convenience of playing, but if the height of the saddle is actually changed, the saddle is fine, but the tension of the saddle and the length of the saddle are changed. Since the influence of the pitch has more influence on the change of the tension than the change of the string length, the string length becomes slightly longer when the saddle 2311 becomes higher, but the pitch becomes higher because more tension is generated.

The saddle height determination unit 130 determines the saddle height variation value of the corresponding line through comparison of the first and second notes in the sound comparator as described above. If the first note is exactly F3 (174.614Hz) instead of the theoretical F3 (174.614Hz), whereas the second note is exactly E3 (164.814Hz) Hz), the saddle height change value for lowering the height of the saddle can be calculated to lower the first sound. The change value may be calculated as a specific value, or may simply be an indication that the height of the bird is lower or higher than the current height.

With reference to Figs. 4 and 5, the height of the saddle can preferably be changed by rotation of the vertical adjustment screw 2313 for height adjustment as described above. According to a preferred embodiment of the present invention, the saddle height adjusting screw 2313 provided on the guitar may further include a storage unit (not shown) storing the thread information. Preferably the length of the thread is 0.7 mm. The thread information indicates a height change value of the saddle when the screw rotates one time. The value obtained by dividing the saddle height change value determined by the saddle height determination section by the thread information may be a rotation value of the screw.

In the case of Gibson's tunedomatic bridge, where the height of individual saddles can not be adjusted and only the height of the entire saddle is adjusted, only two stud screws (the stud screws in rows 1 and 6) Since you only need to adjust the height, adjusting the height of line 1 and line 6 automatically adjusts the height of the remaining 2345 lines automatically. Of course, in the case of a fender-style bridge that can control the height of the saddle on each line, you must adjust the height of each line from line 1 to line 6.

The embodiment of the present invention described above is applied to n = 11 and n + 1 = 12 pratt, but the present invention is also applicable to n = 16 and n + 1 = 17 pratt as another embodiment. In this case, the first note and the second note are in a relationship of three degrees of difference.

According to a preferred embodiment of the present invention, the display unit may further include a display unit (not shown) for visually indicating a change value of the saddle height or the rotation value of the nut. The display unit may be any display means capable of visually transmitting information including a liquid crystal display. Preferably, the display unit may visually indicate an indication indicating a direction of lowering or height of the saddle or a direction of turning the screw, in a change value of the saddle height according to the saddle height determining unit.

According to a preferred embodiment, the bridge may include a driver for automatically adjusting the height of the saddle. The driving unit includes a motor whose height of the saddle is rotated to a corresponding change value based on the saddle height change value determined by the saddle height determination unit. The motor is connected to a vertical screw for height adjustment of the saddle, and the screw is rotated according to the rotation of the motor to adjust the height of the saddle. According to the present invention, it is preferable to configure the motor so that the motor is gradually adjusted to a correct line height every time the set-up method of the present invention is performed by setting the rotation limit value in advance when the motor rotates once.

FIG. 7 illustrates another embodiment of the present invention. In FIG. 7, a note receiving unit 113 is located on the neck to receive a first note generated between a No. 11 prune and a nut 221, Another sound receiving unit 111 (231) is positioned in the body to receive a second sound generated between the first sound receiving unit 111 and the second sound receiving unit. The sound receiving unit 113 preferably has a shape that can be fitted to the neck in a form capable of being attached to the neck. The sound receiving unit 113 receives the vibration of the string and converts it into an electric signal in the same manner as the pickup 113 and 231 provided in the body as a pickup type. The sound receiving unit 113 may be connected to the sound comparing unit 120 according to the present invention by a wire or wirelessly. The method of transmitting the electric signal by wire / wireless is a known technique, and a description thereof will be omitted. The sound receiving unit 111 (231) receiving the second sound is preferably a pickup 231 located in the guitar body, but may be configured to receive sound in the form of a separate microphone. When the pick-up 231 is used as the sound receiving unit 111 for receiving the second sound, it may be connected to the sound comparing unit 120 according to the present invention through the jack 235. According to a preferred embodiment, the saddle height change value and the screw rotation value can be visually displayed to the player through the display unit 150. [ The player can appropriately change the height of the saddle on the basis of the change value of the saddle height and the screw rotation value appearing on the display unit.

FIG. 8 is a signal waveform spectrum graph of the second sound according to the frequency when the height of the saddle of the sixth line is adjusted according to the present invention. FIG. 9 is an enlarged graph of a specific frequency spectrum in FIG. Here, the state where the line height (saddle height) is lower than the proper height is shown in red, the high state is shown in blue, and the case where the line height is desired according to the present invention is shown in green.

FIG. 9 is an enlarged view of a specific region in FIG. 8, and it can be seen that when the spectrum of the present signal waveform is viewed, a pitch difference occurs for each line height. The change in the line height is the difference between the line height and the line height at a distance of less than ± 0.35 mm (the degree of turning the height adjusting screw with a thread length of 0.7 m to less than half a turn) to be. As can be seen from the frequency of about 164 Hz having the largest value, there is almost no difference in the pitch variation with respect to the line height. However, it can be seen that the difference is doubled with each harmonic. Generally speaking, when you hold a plat and play a string to make a sound, the frequency of the loudest sound is recognized as the pitch of the sound. However, since the harmonic of the frequency also occurs at the same time, the frequency of harmonics must also be tuned correctly. Can be expected.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventive concept as defined by the appended claims. But is not limited thereto.

In the above-described exemplary system, the methods are described on the basis of a flowchart as a series of steps or blocks, but the present invention is not limited to the order of the steps, and some steps may occur in different orders . It will also be understood by those skilled in the art that the steps shown in the flowchart are not exclusive and that other steps may be included or that one or more steps in the flowchart may be deleted without affecting the scope of the invention.
