String Instruments

Abstract

This is a stringed instrument with a new structure that can amplify the sound in an analogue way. Since the auxiliary string (40) is installed inside the main body (10), when the user plucks the string (30) to play, the auxiliary string (40) vibrates with the vibration of the string (30) and amplifies the sound generated by the string (30). Therefore, there is an advantage that the sound generated when playing the stringed instrument becomes richer.

Description

[Technical field]

[0001] The present invention relates to a stringed instrument of a new structure that is capable of amplifying the sound in an analogue manner. [Background technology]

[0002] Generally, an acoustic guitar used for musical accompaniment, etc., is composed of a body 10 having a space formed therein, a neck 20 extending forward from one side of the body 10 and having pegs 21 at its front end, and a plurality of strings 30 whose both ends are fixed to the pegs 21 and the body 10, as shown in FIG. 1 and FIG. 2.

[0003] The body 10 is formed in a cylindrical shape having a top plate 11, a sound hole 12 is formed in the top plate 11, and a bridge 13 is provided on the top plate 11.

[0004] Both ends of the string 30 are fixed to the tuning pegs 21 and the bridge 13 .

[0005] Therefore, when a user plucks the string 30, the string 30 vibrates to generate sound, and at this time, the body vibrates to amplify the sound, allowing people nearby to hear loud music.

[0006] However, since the sound of such an acoustic guitar is generated simply by the vibration of the strings 30 provided on the outside of the body 10, the sound produced may be poor.

[0007] To solve these problems, electric guitars were developed that use pickup coils to amplify the sound, but these electric guitars give a different feeling by amplifying the sound in an analog way, so a new method was needed that could amplify the sound in an analog way and give a richer feeling.

[0008] This problem occurs not only in the acoustic guitar mentioned above, but also in all kinds of stringed instruments that have strings 30 and a body with a space formed inside, such as classical guitars, ukuleles, violins, cellos, etc.

[0009] Meanwhile, the string 30 is classified into a type having straight ends and a type having a ball end 41 at one end as shown in FIG. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The present invention will now be described in detail with reference to the accompanying drawings, in which: FIG.

[0022] 4 to 9 show a stringed instrument according to the present invention, which is applied to a general acoustic guitar having six strings 30 as an example.

[0023] According to this, the stringed instrument is the same as in the conventional instrument in that it is composed of a body 10 with a space formed inside, a neck 20 extending forward from one side of the body 10 and having a peg 21 at its front end, and a plurality of strings 30 whose both ends are fixed to the pegs 21 and the body 10.

[0024] At this time, the body 10 is formed in a cylindrical shape having a top plate 11, a sound hole 12 is formed in the top plate 11, and a bridge 13 is provided on the top plate 11.

[0025] Both ends of the string 30 are fixed to the tuning pegs 21 and the bridge 13 .

[0026] According to the present invention, an auxiliary string 40 is provided inside the main body 10 .

[0027] To explain this in more detail, a through hole 14 is formed on one side of the body 10, and an auxiliary through hole 15 is formed on the other side of the body 10.

[0028] The through hole 14 is formed in the front peripheral surface of the main body 10 , and the auxiliary through hole 15 is formed in the rear peripheral surface of the main body 10 .

[0029] A support member 50 coupled to the through hole 14 and an auxiliary thread winder 61 provided on the other side of the main body 10 are further provided.

[0030] As shown in Figures 5 and 7, the support member 50 is composed of a support plate 51 having six fixing holes 51a formed to penetrate the front and rear surfaces, and a pair of extension plates 52 extending rearward on both sides of the rear surface of the support plate 51.

[0031] The auxiliary thread winder 61 is provided on an auxiliary support member 62 connected to the auxiliary through hole 15 .

[0032] The auxiliary support member 62 includes an auxiliary support plate 62a connected to the auxiliary through hole 15, and an auxiliary extension plate 62b extending forward from the auxiliary support plate 62a.

[0033] As shown in FIGS. 4 and 8, the auxiliary thread winders 61 are made up of six pieces and are fixed to the auxiliary extension plate 62b, and an operating lever 61a for operating the auxiliary thread winders 61 extends outside the main body 10.

[0034] The auxiliary string 40 is a type having a ball end 41 at the front end, and six of them are provided to correspond to the strings 30. The front end is connected to the support member 50 so that the ball end 41 is engaged with the fixing hole 51a of the support member 50, and the rear end is connected to the auxiliary thread winder 61.

[0035] Therefore, after the rear end of the auxiliary string 40 is passed through the fixing hole 51a in front of the support member 50 and connected to the auxiliary spool 61, the operating lever 61a of the auxiliary spool 61 is operated to wind the auxiliary string 40 around the auxiliary spool 61, whereby the ball end 41 of the auxiliary string 40 is engaged and fixed in place in the fixing hole 51a.

[0036] Then, when the auxiliary windings 61 are further tightened, the auxiliary strings 40 are pulled taut, and the sound of each auxiliary string 40 is adjusted.

[0037] At this time, it is preferable that each auxiliary string 40 is tuned to C, E, G, B, D, and F#, respectively.

[0038] The main body 10 is provided with a sound silencing device 70 that selectively contacts the auxiliary string 40 to silence the auxiliary string 40 .

[0039] As shown in FIG. 8 and FIG. 9, the silencing device 70 is composed of a silencing member 71 that selectively comes into contact with the auxiliary string 40 to silence the auxiliary string 40, a rotating bar 72 that extends rearward from the silencing member 71 and is connected to a bracket 73 provided on the auxiliary extension plate 62b so as to be rotatable in the vertical direction, an elastic member 74 that is connected to the rotating bar 72 and applies pressure so that the silencing member 71 comes into close contact with the auxiliary string 40, an extension cable 75 that is connected to the rotating bar 72, and a footstool 76 that is connected to an end of the extension cable 75 and is connected to a support base 77 so as to be rotatable in the vertical direction.

[0040] The extension cable 75 is composed of an internal cable 75a, the both ends of which are connected to the pivot bar 72 and the footrest 76, and a housing 75b configured to surround the outside of the internal cable 75a, and the internal cable 75a is configured to be slidable inside the housing 75b.

[0041] Such an extension cable 75 is generally used for bicycle brakes, etc., and therefore further detailed description thereof will be omitted.

[0042] Therefore, under normal circumstances, the elastic member 74 brings the sound absorbing member 71 into close contact with the auxiliary string 40 to prevent the auxiliary string 40 from vibrating. When the user steps on the footstool 76, the internal cable 75a is pulled to rotate the rotating bar 72 downward, and the sound absorbing member 71 moves away from the auxiliary string 40 to allow the auxiliary string 40 to vibrate.

[0043] The stringed instrument constructed as above has the auxiliary string 40 inside the body 10, so that when a user plucks the string 30 to play, the auxiliary string 40 vibrates due to the vibration of the string 30, amplifying the sound generated by the string 30.

[0044] This has the advantage of making the sound produced when playing a stringed instrument richer.

[0045] A through hole 14 is formed on one side of the body 10, a support member 50 connected to the through hole 14, and an auxiliary spool 61 provided on the other side of the body 10 are further provided. Both ends of the auxiliary strings 40 are fixed to the support member 50 and the auxiliary spool 61, so that the sound of each auxiliary string 40 can be adjusted by operating the auxiliary spool 61.

[0046] In particular, an auxiliary through hole 15 is formed on the other side of the main body 10, an auxiliary support member 62 is connected to the auxiliary through hole 15, and the auxiliary spool 61 is provided on the auxiliary support member 62, which has the advantage of making it easy to install the auxiliary spool 61.

[0047] In addition, the main body 10 is further provided with a silencing device 70 that selectively comes into contact with the auxiliary string 40 to silence the auxiliary string 40. A user can adjust the silencing device 70 so that the silencing member 71 is in close contact with the auxiliary string 40 or spaced apart from the auxiliary string 40, thereby adjusting whether the auxiliary string 40 generates sound or not.

[0048] Therefore, there is an advantage that the user can freely adjust the tone of the stringed instrument while playing the stringed instrument.

[0049] In this embodiment, the auxiliary string 40 has a ball end 41 at one end. However, when an auxiliary string 40 without a ball end 41 is used, as shown in FIG. 10, a ring 53 is provided on the support member 50 so that the front end of the auxiliary string 40 can be engaged and fixed to the ring 53.

[0050] In addition, although the auxiliary spool 61 is provided on the auxiliary member 62 in the above embodiment, the auxiliary spool 61 may be provided directly on the main body 10 as shown in FIG.

[0051] The silencing device 70 has been illustrated as being configured so that the user can operate it by stepping on it with their foot. However, as shown in FIG. 11 and FIG. 12, the silencing device 70 may be configured so that a rotating bar 72 connected to the silencing member 71 extends outside the main body 10 and the user can rotate the rotating bar 72 by hand to adjust the silencing member 71 to be in close contact with or away from the auxiliary string 40.

[0052] Alternatively, the sound deadening device 70 may utilize an electrically operated actuator.

[0053] The sound deadening device 70 may be configured so that the sound deadening member 71 can be fixed in a state spaced apart from the auxiliary string 40 .

[0054] The positions of the through hole 14 and the auxiliary through hole 15 can be freely changed.

[0055] In addition, the extension cable 75 can be detachably connected to the pivot bar 72 or the footstool 76, and can be configured so that the middle portion of the extension cable 75 can be separated, if necessary.

[0056] In addition, by providing frets or separate support rods at locations where the auxiliary string 40 may come into contact with various parts of the stringed instrument and supporting the various parts of the auxiliary string 40 with the frets or support rods, it is possible to prevent the auxiliary string 40 from coming into contact with various parts of the stringed instrument and to shorten the range over which the auxiliary string 40 vibrates, i.e., its length, thereby improving the tone quality.

[0057] 13 to 15 show another embodiment of the present invention, in which a through hole 14 is formed on one side of the body 10, and a support frame 90 to which the auxiliary string 40 is fixed is provided in the through hole 14.

[0058] The support frame 90 includes a first support plate 91 detachably connected to the through hole 14, a second support plate 92 spaced apart from the first support plate 91, a support bar 93 connecting the first and second support plates 91, 92, and an auxiliary spool 94 provided on the second support plate 92.

[0059] The first support plate 91 is detachably coupled to the through hole 14 using fixing screws (not shown).

[0060] The first support plate 91 is formed with a fixing hole 91a to which the ball end 41 of the auxiliary string 40 is fixed.

[0061] Therefore, with the support frame 90 separated, both ends of the auxiliary strings 40 are coupled to the fixing holes 91a and auxiliary spools 94 of the support frame 90, the auxiliary strings 40 are tuned by adjusting the auxiliary spools 94, and the support frame 90 is then inserted into the main body 10 through the through holes 14 and fixed therein, thereby completing the installation of the auxiliary strings 40.

[0062] In the stringed instrument constructed as above, the auxiliary string 40 is connected to the support frame 90 which is detachably connected to the through hole 14, so that the support frame 90 can be separated to install or replace the auxiliary string 40.

[0063] Therefore, there is an advantage that the auxiliary string 40 can be easily installed or replaced.

[0064] In this embodiment, the auxiliary thread spool 94 is illustrated as being provided on the second support plate 92, but it is also possible to form the fixing hole 51a in the second support plate 92 and provide the auxiliary thread spool 94 on the first support plate 91.

[0065] In addition, in this embodiment, the structure of the silencer 70 is omitted, but it is also possible to provide the silencer 70 on one side of the support frame 90 .

[0066] In addition, although the present embodiment has been illustrated as having one support frame 90, the present invention is not limited thereto. A plurality of support frames may be installed within the space permitted within the stringed instrument. For example, two support frames may be arranged crosswise in an "X" shape within the stringed instrument.

[0067] Also, although not shown, the support frame 90 may be fixed to one or more of the top plate, side plate, and bottom plate of the stringed instrument inside the stringed instrument. For example, the support frame 90 may be directly fixed to the top plate 11 inside the stringed instrument, or a fixed brace structure fixed to the top plate 11 may be disposed. Thus, the support plates 91 and 92 of the support frame 90 may be fixed to the body 10. However, the present invention is not limited thereto, and an additional fixing means for fixing the body of the support frame 90 may be disposed between the support frame 90 and the rear plate of the body 10 (the plate opposite the top plate 11), and the support frame 90 may be firmly supported to the body 10 by the additional fixing means and the fixed brace structure.

[0068] Although not shown, a support rail (not shown) for facilitating attachment and detachment of the support frame 90 may be further provided inside the main body 10. The support rail (not shown) may be fixed to the upper plate 11 and the rear plate, for example, and the support frame 90 may be firmly supported to be detachable from the upper plate 11 and the rear plate through the rail.

[0069] 16 and 17 show another embodiment of the present invention, in which the rear end of the string 30 passes through the body 10 and extends into the interior of the body 10. As shown in FIG.

[0070] For this purpose, the bridge 13 and the top plate 11 are formed with communication holes 11a, 13a through which the rear ends of the strings 30 pass, and an auxiliary bridge 16 is provided on the periphery of the body 10.

[0071] At this time, the string 30 has the ball end 41 at the rear end.

[0072] An auxiliary through hole 15 is formed in the circumferential surface of the main body 10, that is, in the rear side surface of the main body 10.

[0073] The auxiliary bridge 16 has a plurality of fixing holes 16 a through which the strings 30 pass, and is connected to the auxiliary through holes 15 .

[0074] A method of installing the strings 30 in the stringed instrument constructed as above will be described as follows.

[0075] First, the front end of the string 30 is connected to the fixing hole 16a at the rear of the auxiliary bridge 16, and then the string 30 is extended to the outside of the body 10 through the communication holes 11a and 13a.

[0076] When the tip of the string 30 is connected to the tuning peg 21 and the tuning peg 21 is tightened, the string 30 is pulled and the ball end 41 is engaged in the fixing hole 16 a of the auxiliary bridge 16 .

[0077] Then, the installation of the strings 30 can be completed by further tightening the pegs 21 to tune each string 30.

[0078] The stringed instrument constructed in this manner has an advantage that the structure is simpler than the above-mentioned embodiment in which the rear ends of the strings 30 extend inside the body 10 and therefore the auxiliary strings 40 must be installed separately.
