Therefore, it has the advantage of producing a richer sound when playing the stringed instrument.

Description

Technical Field

[0001] The present invention relates to a stringed instrument with a new structure, which can amplify resonance in an analog manner. Background Art

[0002] Usually, such as Figure 1 and Figure 2 As shown, an acoustic guitar used for accompaniment, etc. includes: a body (10) having a space portion formed therein; a neck (20) extending from one side of the body (10) toward the front, and a tuning peg (21) is provided at the front end of the neck (20); and a plurality of strings (30) having both ends fixed to the tuning peg (21) and the body (10).

[0003] The main body (10) is formed in a cylindrical shape with a panel (11), a sound hole (12) is formed in the panel (11), and a bridge (13) is provided on the panel (11).

[0004] The two ends of the string (30) are fixed to the string axis (21) and the bridge (13).

[0005] Therefore, when a user plucks the string (30), the string (30) vibrates and generates sound, and at this time, the body of the instrument vibrates and amplifies the sound, so that people around can hear the loud music.

[0006] However, this acoustic guitar generates sound only through the resonance of the strings (30) provided outside the body (10), and therefore has a problem in that the sound appears thin.

[0007] To solve this problem, electric guitars that use telecoils to amplify sound were developed. However, this type of electric guitar provides a different feel by amplifying sound through analog means, so a new method of providing a richer sound by amplifying resonance through analog means is needed.

[0008] This problem occurs not only in the above-mentioned acoustic guitar, but also in all types of stringed instruments including strings (30) and a body forming a space portion therein, such as a classical guitar, ukulele, violin or cello.

[0009] On the other hand, the string (30) includes a type with straight ends and a type with a ball head (41) at one end (such as Figure 3 shown). Summary of the Invention

[0036] Hereinafter, the present invention will be described in detail based on the accompanying exemplary drawings.

[0037] Figures 4 to 9 This is a diagram showing a stringed instrument of the present invention, and illustrates an example of an ordinary acoustic guitar provided with six strings (30).

[0038] Accordingly, the stringed instrument comprises: a main body (10) having a space formed therein; a neck (20) extending forward from one side of the main body (10), with a peg (21) provided at the front end of the neck (20); and a plurality of strings (30) with both ends fixed to the peg (21) and the main body (10), which is the same as the existing structure.

[0039] At this time, the main body (10) is formed in a cylindrical shape with a panel (11), a sound hole (12) is formed in the panel (11), and a bridge (13) is provided on the panel (11).

[0040] The two ends of the string (30) are fixed to the string axis (21) and the bridge (13).

[0041] In addition, according to the present invention, an auxiliary string (40) is provided inside the main body (10).

[0042] To explain this in detail, a through hole (14) is formed on one side of the main body (10), and an auxiliary through hole (15) is formed on the other side of the main body (10).

[0043] The through hole (14) is formed on the front peripheral surface of the main body (10), and the auxiliary through hole (15) is formed on the rear peripheral surface of the main body (10).

[0044] In addition, it also includes: a supporting member (50) coupled to the through hole (14); and an auxiliary string axis (61) arranged on the other side of the main body (10).

[0045] like Figure 5 and Figure 7 As shown, the support member (50) includes: a support plate (51) having six fixing holes (51a) formed therein and penetrating the front and rear surfaces; and a pair of extension plates (52) extending rearward from both sides of the rear surface of the support plate (51).

[0046] The auxiliary peg (61) is provided on an auxiliary supporting member (62), and the auxiliary supporting member (62) is coupled to the auxiliary through hole (15).

[0047] The auxiliary support member (62) includes: an auxiliary support plate (62a) coupled to the auxiliary through hole (15); and an auxiliary extension plate (62b) extending forward from the auxiliary support plate (62a).

[0048] like Figure 4 and Figure 8 As shown, the auxiliary string pegs (61) are composed of six pieces and are fixed to the auxiliary extension plate (62b), and the operating rod (61a) for operating the auxiliary string pegs (61) extends to the outside of the main body (10).

[0049] The auxiliary string (40) is a type having a ball head (41) at the front end thereof and is composed of six strings so as to correspond to the string (30). The front end thereof is coupled to the support member (50) so that the ball head (41) is stuck in the fixing hole (51a) of the support member (50), and the rear end thereof is coupled to the auxiliary string axis (61).

[0050] Therefore, in front of the supporting member (50), the rear end of the auxiliary string (40) is coupled to the auxiliary string peg (61) through the fixing hole (51a), and then the operating rod (61a) of the auxiliary string peg (61) is operated to wind the auxiliary string (40) around the auxiliary string peg (61), so that the ball head (41) of the auxiliary string (40) is stuck and fixed in the fixing hole (51a).

[0051] In addition, when the auxiliary pegs (61) are further tightened, the auxiliary strings (40) are tightened, and the sound of each auxiliary string (40) is adjusted.

[0052] At this time, preferably, each auxiliary string (40) is tuned to C, E, G, B, D, F# respectively.

[0053] In addition, a silencer (70) is provided on the main body (10), and the silencer (70) selectively contacts the auxiliary string (40) to silence the auxiliary string (40).

[0054] like Figure 8 and Figure 9 As shown, the silencer (70) includes: a silencer member (71) that selectively contacts the auxiliary string (40) to silence the auxiliary string (40); a rotating rod (72) that extends rearward from the silencer member (71) and is coupled to a bracket (73) in a manner that can rotate in the up and down directions, and the bracket (73) is provided on the auxiliary extension plate (62b); an elastic member (74) that is connected to the rotating rod (72) and pressurizes the silencer member (71) so that the silencer member (71) is closely attached to the auxiliary string (40); an extension cable (75) that is connected to the rotating rod (72); and a pedal (76) that is connected to the end of the extension cable (75) and is coupled to a support frame (77) in a manner that can rotate in the up and down directions.

[0055] The extension cable (75) includes an inner cable (75a) having both ends connected to the rotating rod (72) and the pedal (76), and a housing (75b) configured to surround the outer side of the inner cable (75a). The inner cable (75a) is configured to be slidable inside the housing (75b).

[0056] Such an extension cable (75) is generally used for a brake of a rotator, etc., and therefore further detailed description thereof will be omitted.

[0057] Therefore, under normal circumstances, the muffler member (71) is tightly attached to the auxiliary string (40) through the elastic member (74) to prevent the auxiliary string (40) from vibrating, and when the user steps down on the pedal (76), the inner cable (75a) is pulled and causes the rotating rod (72) to rotate downward, so that the muffler member (71) is separated from the auxiliary string (40), thereby allowing the auxiliary string (40) to vibrate.

[0058] In the stringed instrument constructed as described above, an auxiliary string (40) is provided inside the main body (10), so when a user plucks the string (30) to play, the auxiliary string (40) vibrates through the vibration of the string (30) and amplifies the sound produced by the string (30).

[0059] Therefore, there is an advantage that the sound produced when playing the string instrument is richer.

[0060] In addition, a through hole (14) is formed on one side of the main body (10), and the main body (10) further includes a support member (50) coupled to the through hole (14) and an auxiliary chord axis (61) provided on the other side of the main body (10). Both ends of the auxiliary string (40) are fixed to the support member (50) and the auxiliary chord axis (61), thereby having the advantage that the sound of each auxiliary string (40) can be adjusted by the auxiliary chord axis (61).

[0061] In particular, an auxiliary through hole (15) is formed on the other side of the main body (10), the auxiliary supporting member (62) is coupled to the auxiliary through hole (15), and the auxiliary chord pin (61) is arranged on the auxiliary supporting member (62), thereby having the advantage of being easy to arrange the auxiliary chord pin (61).

[0062] In addition, the main body (10) further includes a silencer (70) that selectively contacts the auxiliary string (40) to silence the auxiliary string (40). A user operates and adjusts the silencer (70) to make the silencer member (71) closely attached to the auxiliary string (40) or separated from the auxiliary string (40), thereby adjusting the auxiliary string (40) to generate or not generate sound.

[0063] Therefore, there is an advantage in that the user can freely adjust the timbre of the string instrument when playing the string instrument.

[0064] In the present embodiment, the auxiliary string (40) is exemplified as a type having a ball head (41) at one end. However, when an auxiliary string (40) without a ball head (41) is used, as shown in FIG. Figure 10 As shown, a ring (53) is provided on the supporting member (50), so that the front end of the auxiliary string (40) can be hooked and fixed on the ring (53).

[0065] In addition, the auxiliary string pin (61) is provided on the auxiliary member (62), but Figure 11 As shown, the auxiliary peg (61) can be directly arranged on the main body (10).

[0066] In addition, the muffler (70) is illustrated as being operable by a user by stepping on it, but as Figure 11 and Figure 12 As shown, the rotating rod (72) connected to the sound-absorbing member (71) can be configured to extend toward the outside of the main body (10), and the user can manually rotate the rotating rod (72) to adjust so that the sound-absorbing member (71) is tightly attached to the auxiliary string (40) or separated from the auxiliary string (40).

[0067] Alternatively, the muffler (70) may also utilize an electric operating device operated by electricity.

[0068] In addition, the muffler (70) may be configured such that the muffler member (71) is fixed in a state where the muffler member (71) is separated from the auxiliary string (40).

[0069] In addition, the positions of the through hole (14) and the auxiliary through hole (15) can be freely changed.

[0070] In addition, the extension cable (75) may be detachably coupled to the rotating rod (72) or the pedal (76), and may be configured such that the middle portion of the extension cable (75) may be separated as needed.

[0071] In addition, a flat plate or a separate support rod is provided at a position where the auxiliary string (40) may contact various parts of the string instrument. The flat plate or the support rod supports various parts of the auxiliary string (40), thereby preventing the auxiliary string (40) from contacting various parts of the string instrument and improving the timbre by shortening the vibration range, i.e., the length, of the auxiliary string (40).

[0072] Figures 13 to 15 The figure shows another embodiment of the present invention, wherein a through hole (14) is formed on one side of the main body (10), and a support frame (90) for fixing the auxiliary string (40) is provided in the through hole (14).

[0073] The support frame (90) includes: a first support plate (91) detachably coupled to the through hole (14); a second support plate (92) spaced apart from the first support plate (91); a support rod (93) connecting the first support plate (91) and the second support plate (92); and an auxiliary chord axis (94) disposed on the second support plate (92).

[0074] The first support plate (91) is detachably coupled to the through hole (14) using fixing screws (not shown).

[0075] In addition, a fixing hole (91a) is formed on the first support plate (91), and the ball head (41) of the auxiliary string (40) is fixed in the fixing hole (91a).

[0076] Therefore, when the support frame (90) is separated, the two ends of the auxiliary string (40) are respectively combined with the fixing hole (91a) and the auxiliary string axis (94) of the support frame (90), and each auxiliary string (40) is adjusted by adjusting the auxiliary string axis (94). Then, the support frame (90) is inserted into the interior of the main body (10) through the through hole (14) and fixed, thereby completing the setting of the auxiliary string (40).

[0077] In the stringed instrument constructed as described above, the auxiliary string (40) is combined with the support frame (90), and the support frame (90) is detachably combined with the through hole (14), so that the auxiliary string (40) can be set or replaced by separating the support frame (90).

[0078] Therefore, it has the advantage of being easy to set or replace the auxiliary string (40).

[0079] In the case of this embodiment, the auxiliary chord axis (94) is illustrated as being provided on the second support plate (92), but the fixing hole (51a) can also be formed on the second support plate (92), and the auxiliary chord axis (94) can be provided on the first support plate (91).

[0080] In addition, in the case of this embodiment, although the structure of the muffler (70) is omitted, the muffler (70) can also be provided on one side of the support frame (90).

[0081] In addition, in this embodiment, the support frame (90) is provided as one, but the present invention is not limited thereto. Within the scope allowed by the storage space inside the string instrument, multiple support frames can be provided. For example, two support frames can be arranged crosswise in an "X" shape inside the string instrument.

[0082] In addition, although not shown, the support frame (90) can be fixed to one or more of the panel, side panels, and back panel of the string instrument inside the string instrument. For example, a fixing bracket structure directly fixed to the panel (11) or fixed to the panel (11) is configured inside the string instrument. Therefore, the support plates (91, 92) of the support frame (90) can be fixed to the main body (10). However, the present invention is not limited to this, and an additional fixing tool for fixing the support frame (90) to the main body can be configured between the support frame (90) and the back panel (the plate opposite to the panel (11)) of the main body (10), and the support frame (90) can be firmly supported on the main body (10) by the additional fixing tool and the fixing bracket structure.

[0083] In addition, although not shown in the figure, a support rail (not shown) for facilitating the removal of the support frame (90) may be provided inside the main body (10). For example, the support rail (not shown) may be fixed to the panel (11) and the back panel, and the support frame (90) may be firmly supported on the panel (11) and the back panel via the rail in a detachable manner.

[0084] Figure 16 and Figure 17 This is a diagram showing another embodiment of the present invention, in which the rear end portion of the string (30) passes through the body (10) and extends toward the inside of the body (10).

[0085] To this end, communicating holes (11a, 13a) for the rear end of the string (30) to pass through are formed in the bridge (13) and the panel (11), and auxiliary bridges (16) are provided on the peripheral surface of the main body (10).

[0086] At this time, the string (30) has a form in which the ball head (41) is provided at the rear end.

[0087] In addition, an auxiliary through hole (15) is formed on the peripheral surface of the main body (10), that is, the rear side surface of the main body (10).

[0088] The auxiliary bridge (16) is formed with a plurality of fixing holes (16a) for the strings (30) to pass through, and the auxiliary bridge (16) is coupled to the auxiliary through hole (15).

[0089] In the stringed instrument constructed as described above, a method of setting the strings (30) is described below.

[0090] First, behind the auxiliary bridge (16), the front end of the string (30) is coupled to the fixing hole (16a), so that the string (30) extends to the outside of the main body (10) through the connecting holes (11a, 13a).

[0091] In addition, when the front end of the string (30) is coupled to the peg (21) and the peg (21) is tightened, the string (30) is tightened and the ball head (41) is stuck in the fixing hole (16a) of the auxiliary bridge (16).

[0092] In addition, each string (30) is adjusted by further tightening the pegs (21), thereby completing the setting of the strings (30).

[0093] Compared with the above embodiment which requires the provision of additional auxiliary strings (40), the stringed instrument constructed as described above has the advantage of a simpler structure because the rear end of the string (30) extends toward the interior of the main body (10).
