(12) Referring to FIG. 1 and FIG. 3, FIG. 1 is a schematic diagram of a structure of an embodiment of the present invention, and FIG. 3 is a sectional diagram of the structure of an embodiment of the present invention.

(13) As shown in FIG. 1 and FIG. 3, the adjusting member 100 of the embodiment of the present invention is made up of a main body 101 and at least one adjusting arm 102. The main body 101 has a short and small columnar structure, and the at least one adjusting arm 102 is mounted on the main body 101. In the present embodiment, the adjusting arm 102 has a long rod-shaped, and the long rod-shaped is cylindrical long rod-shaped, and the adjusting member 100 is pivoted/revolved (rotated) on the sound post 10 to become a part of the sound post 10.

(14) Of course, the adjusting member 100 in this embodiment can be applied to any adjustable sound post 10. In this embodiment, material of the adjusting member 100 is aluminum or aluminum alloy. In addition, the adjusting member 100 is coated with a first coating, and material of the first coating is selected from titanium, titanium nitride, titanium carbide, copper, gold, nickel and combinations thereof. In other embodiments, a second coating is coated on the first coating, and material of the second coating is diamond-like carbon (DLC).

(15) In this embodiment, the first coating and the second coating may be implemented by a physical or chemical coating process of sputtering, plasma, laser or electric arc. Because the sound post plays a role of transmitting sound vibration, through the coating process, the hardness of all components of the sound post 10 can be greatly enhanced such that the sound conduction effect is excellent and clear music can be created.

(16) Therefore, in other embodiments, the adjusting member 100 can be coated with the first and second coatings, and the other components used in the sound post 10 can also be coated with the same first and second coatings.

(17) For a better understanding of the structural features of the adjusting member 100 of the present invention, please refer to FIG. 2, it illustrates a diagram of three-dimensional structurally actuating of one embodiment of the present invention. As shown in FIG. 2, it can be seen that a number of the at least adjusting arm 102 in the adjusting member 100 is five and the at least one adjusting arm 102 is configured perpendicularly to the main body 101, and endpoint P1 of each adjusting arm 102 jointly forms a regular pentagon along the indicating line P2. Accordingly, when the tightness of the sound post 10 is needed to be adjusted, any of the rod-shaped objects can be directly inserted into the music instrument, and the whole adjusting member 100 can be rotated along the direction of an arrow A2 against any adjusting arm 102. When the main body 101 of the adjusting member 100 rotates in the direction of the arrow A2, it moves along an arrow A3 on a stud (screw post) 300 to adjust length of the whole sound post 10, accordingly to achieve the purpose of adjusting the tightness of the sound post.

(18) In the present embodiment, the main body 101 and the adjusting arm 102 in the adjusting member 100 may be integrally formed, or the adjusting arm 102 may be tightly bonded to the main body 101 by an ebonite adhesive. The parts of the present embodiment are in a very tight bonding state when they are fixed. Besides the merits of the coating, noise of vibration and collision between the components caused by non-tightly combining of the sound post 10 in resonance can be avoided as the sound post 10 is in resonance.

(19) As shown in FIG. 1-3, the sound post 10 provided with the adjusting member 100 in this embodiment comprises a first post 200, a screw post 300 and a second post 400. The first post 200 is provided with a first hollow thread 204 and a first fit part 201, and the screw post 300 is pivoted (rotated) to the first hollow thread 204.

(20) The second post 400 is provided with a second hollow thread 404 and a second fit part 401, and the second hollow thread 404 is pivoted to the screw post 300. The adjusting member 100 is pivoted on the screw post 300 and arranged between the first post 200 and the second post 400.

(21) The first fit part 201 comprises a first spherical joint 202 and a first cap 203, and the first cap 203 is located on the first spherical joint 202. Similarly, the second fit part 401 comprises a second spherical joint 402 and a second cap 403, and the second cap is located on the second spherical joint 402. Therefore, taking the first fit part 201 as an example, the first fit part 201 can rotate arbitrarily in the direction of the arrow A1 shown in FIG. 2 to adjust the angle, which is fitted to sound box with a curvature of a music instrument.

(22) In addition, in this embodiment, a regulating member 500 is also pivoted on the screw post 300. The purpose of the regulating member 500 is to fix the first post 200 to stabilize its structure and prevent sound noise caused by the slight vibration and collision of the components.

(23) As shown in FIG. 3, in this embodiment, the screw post 300 is provided with a hollow part 301. In addition, the first hollow thread 204 is connected with the first sound chamber 205, and the second hollow thread 404 is connected with the second sound chamber 405. The first sound chamber 205, the first hollow thread 204 and the second sound chamber 405, the second hollow thread 404 are connected through the hollow part 301. In this embodiment, function of the first sound chamber 205 and the second sound chamber 405 is to adjust resonance sound of the sound post 10. Through the connection of the hollow part 301, the resonance effect can be better.

(24) In particular, material of the screw post 300 is aluminum or aluminum alloy. In addition, a first coating material is coated on the screw post 300, and material of the first coating is selected from titanium, titanium nitride, titanium carbide, copper, gold, nickel and the combination thereof; a second coating is coated on the first coating, and material of the second coating is diamond-like carbon (DLC). In this embodiment, the screw post 300 is also coated with the coatings same as the adjusting member 100, and the screw post 300 bridges the first post 200 and the second post 400. Material of screw post 300 and double coating can provide excellent vibration transmission media.

(25) Referring to FIG. 2 and FIG. 4, FIG. 4 illustrates a sectional diagram of three-dimensional structurally actuating of one embodiment of the invention. As shown in FIG. 2 and FIG. 4, as the adjusting member 100 can be rotated along the direction of the arrow A2, the second post 400 moves in the direction of the arrow A3, and thereby adjusting the length of the sound post 10. In FIG. 4, when the adjusting member 100 rotates in the direction of the arrow A2, the second post 400 moves downward in the direction of the arrow A4. The tightness of the sound post 10 against the music instrument is increased.

(26) Please refer to FIG. 5, FIG. 5 illustrates an actual installation diagram of an embodiment of the invention. The advantage of this embodiment to operate with the adjusting member 100 is that a user can install this sound post 10 through the first post 200, the screw post 300 and the second post 400 installed by utilizing the adjusting member 100 straightly entering into the F sound hole to horizontal state. Subsequently, the first fit part 201 and the second fit part 401 on the first post 200 and the second post 400 are placed sequentially against an upper plate (board) 601 and a lower plate (board) 602 of the sound box 600 of a musical instrument so that the first cap 202 and the second cap 402 can be rotated along the arrow A1 in FIG. 2 to fit to the upper plate 601 and the lower plate 602. After the fitting operation is completed, any long rod-shaped object can be inserted into the sound box 600 of the musical instrument, and the adjusting member 100 can be intuitively rotated to control the tightness of the sound post 10 against the upper plate 601 and the lower plate 602 of the sound box 600, so as to adjust the timbre and resonance effect of the musical instrument.

(27) As is understood by a person skilled in the art, the foregoing preferred embodiments of the present invention are illustrated of the present invention rather than limiting of the present invention. It is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structure. While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
