Description

Technical Field

[0001] The utility model relates to a field, in particular to a guitar string clamp for a cajon drum. Background Art

[0002] The cajon's guitar string holder is a crucial component, crucial to its tone and sound. The guitar string holder is mounted within the cajon's enclosure, securing the guitar strings. When the drumhead is struck, the vibrations are transmitted to the air within the enclosure, causing the air to vibrate, which in turn vibrates the guitar strings. The vibrations of the guitar strings interact with the vibrations of the drum, creating a resonance that enhances the drum's tone and volume, creating a sound similar to that of a jazz drum. By adjusting the tension of the guitar strings or the tightness of the string holder against the drumhead, the frequency and amplitude of the guitar string vibrations can be altered, thereby adjusting the cajon's tone.

[0003] The existing guitar string clamp needs to adjust its own position to change the tightness between the guitar strings and the drum head, which is inconvenient to operate when adjusting and fixing the position. Utility Model Content

[0004] In view of the above-mentioned defects, the purpose of the present invention is to provide a guitar string clamp for a cajon drum, which can push the guitar strings in a certain direction through its own guitar string tightening device, thereby changing the degree of contact between the guitar strings and the drum surface.

[0022] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0023] like Figure 1-3 As shown, a guitar string card plate for a cajon drum includes a base plate 100, guitar strings and a string bending assembly 200;

[0024] The front side of the base plate 100 is provided with nut portions 110 near both ends thereof, and the back side of the base plate 100 is provided with a recessed portion 120. The guitar strings are wound around the base plate 100, passing through the nut portion 110 and the recessed portion 120.

[0025] The inner concave surface of the recessed portion 120 is provided with a string-pushing hollow 130 penetrating to the front surface of the base plate 100;

[0026] The string-bending device includes a bolt 210, a nut 220, a string-bending block 230 and a pressure plate 240. The recessed position 120 is provided with a bolt 210 extending toward the back side. The string-bending block 230 is accommodated in the string-bending hollow 130 and pressed against the guitar strings on the front side of the base plate 100. The pressure plate 240 is slidably mounted on the nut 220 through its own through-hole. The pressure plate 240 is accommodated in the recessed position 120, and the front side of the pressure plate 240 contacts the back side of the string-bending block 230. The nut 220 is mounted on the bolt 210 and abuts against the back side of the pressure plate 240.

[0027] In this solution, a base plate 100 is used as the foundation of a guitar string holder. A string pusher assembly 200 for pushing the guitar strings is provided on the guitar string holder. This allows the string pusher assembly 200 to change the degree of contact between the guitar strings and the drumhead without changing the position of the base plate 100, thereby changing the timbre of the cajon. The string pusher assembly 200 comprises a threaded mating structure consisting of a bolt 210 and a nut 220. By adjusting the distance between the bolt 210 and the nut 220, the nut 220 pushes the pressure plate 240, which in turn pushes the string pusher block 230, and finally the string pusher block 230 pushes the guitar strings. The recessed portion 120 not only provides adjustment space for the pressure plate 240, but also constrains the freedom of rotation of the pressure plate 240 around the bolt 210.

[0028] The two side ends of the base plate 100 are clamping portions 140, which are provided with a plurality of string-receiving grooves. The top of the side wall corresponding to the recessed portion 120 and the clamping portion 140 is also provided with a plurality of string-receiving grooves. A plurality of guitar strings are constrained by the clamping portion 140 on one side of the base plate 100, pass through the two nut portions 110 and the clamping portion 140 on the other side, cross the recessed portion 120, and are constrained by the side wall of the recessed portion 120.

[0029] The guitar strings are installed on the base plate 100 through the string grooves, and the whole is arranged in a surrounding manner, which facilitates the installation of the guitar strings.

[0030] The bolt 210 is located at the center of the recessed position 120 , and the two string-pushing hollows 130 are evenly distributed on both sides of the bolt 210 .

[0031] This design allows the pressure applied by the pressure plate 240 to the string bend block 230 to be relatively uniform, and the force applied by the string bend block 230 to the guitar strings is conducive to uniformly pushing the guitar strings outward.

[0032] The pressing plate 240 is accommodated in the recessed portion 120 , and a hole for passing the bolt 210 is provided at the center of the pressing plate 240 ;

[0033] The width of the pressing plate 240 is smaller than the width of the recessed portion 120 , and the length of the pressing plate 240 is not less than the distance between the center lines of the two string-pushing hollows 130 .

[0034] In addition, the clamping portion 140 further includes a clamping block, which is a protruding block protruding from the upper and lower parts of the side end of the base plate 100 .

[0035] The clamping portion 140 is used to be clamped into the corresponding clamping position of the cajon drum. The clamping portion 140 is protruding to reduce the impact on the strings.

[0036] In addition, the nut 220 is a butterfly nut 220 .

[0037] In addition, the string-bending block 230 is made of sponge.

[0038] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
