Description

Technical Field

[0001] This utility model relates to the field of cello, specifically an adjustable cello soundbar structure. Background Technology

[0002] The cello is a bowed string instrument, belonging to the violin family. Besides being used for solo performances, it also plays the bass strings in chamber music, string orchestras, and ensembles. A cello typically has four strings: C, G, D, and A, from lowest to highest. The A string produces a brilliant, powerful, and lyrical sound; the D string has a more muted tone; and the G and C strings are deep and resonant, capable of handling the very heavy sonic demands of an orchestra. The cello boasts a wide range and is one of the instruments with the most clefs. Its deeply emotionally resonant tone has captivated many listeners and has gradually gained widespread acceptance and appreciation.

[0003] Existing cello bracing serves to support and transmit vibrations. Located inside the cello, especially the bass bracing, it supports the body and helps transmit vibrations in the lower register, thus affecting the cello's tone and sound quality. Specifically, by supporting the body, the bracing ensures that the body can withstand the enormous pressure from the strings during playing, preventing the soundboard from deforming due to excessive pressure. Furthermore, the bracing also transmits vibrations, transferring the vibrations of the back plate to the soundboard, allowing it to vibrate and produce sound. However, existing cello bracing still has the following problems in use:

[0004] Existing cello bracing is susceptible to deformation due to humidity and temperature variations, affecting its stability and performance. Therefore, it is essential to develop an adjustable cello bracing structure for use in the current cello industry. Utility Model Content

Positioning rods 13 are symmetrically fixed between the two soundbar bodies 11 in each set, and each positioning rod 13 has multiple positioning holes 20. The positioning holes 20 on the positioning rods 13 are close to each other. An adjustable stabilizing mechanism 21 is mounted on each of the two positioning rods 13. The adjustable stabilizing mechanism 21 includes a connecting block 2100. U-shaped blocks 2101 are fixedly mounted on both ends of the connecting block 2100. Each U-shaped block 2101 has a slot 2102, which is inserted into the positioning rod 13. Each U-shaped block 2101 has a display port 2103. A fixing block 2104 is fixedly mounted on the connecting block 2100, located between the two display ports 2103. Both sides of the fixed block 2104 are symmetrically fixedly equipped with extension rods 2105. One end of each extension rod 2105 is fixedly equipped with a limit block 2106. Each extension rod 2105 is movably equipped with a movable block 2107. Each movable block 2107 is fixedly equipped with an insertion rod 2108. The insertion rod 2108 is inserted into the positioning hole 20 of the positioning rod 13. The end face of the fixed block 2104 is symmetrically fixedly equipped with connecting rods 2110. One end of each connecting rod 2110 is fixedly equipped with an assembly block 2111. The two connecting rods 2110 are movably equipped with... The movable block 2107 is equipped with an adjusting block 2112. A fixing plate 2113 is fixedly mounted on both symmetrical sides of the adjusting block 2112. An mounting plate 2109 is fixedly mounted on the end face of the movable block 2107. An adjusting rod 2114 is movably mounted on the fixing plate 2113. The other end of the adjusting rod 2114 is movably mounted to the mounting plate 2109. A guide rod 2116 is fixedly mounted on the adjusting block 2112. The guide rod 2116 movably passes through the fixing block 2104 and the connecting block 2100, and a pressure block 2117 is fixedly mounted on one end of the guide rod 2116.

[0031] In this invention, the sound beam body 11 deforms on its sides due to humidity and temperature. The slots 2102 on the two U-shaped blocks 2101 are respectively inserted into the two positioning rods 13. The connecting block 2100 is located between the two positioning rods 13. The adjusting block 2112 moves on the two connecting rods 2110. Under the action of the adjusting rod 2114, the insert 2108 on the movable block 2107 passes through the display port 2103 and engages with the positioning hole 20 on the positioning rod 13, increasing the stability between the adjustable stabilizing mechanism 21 and the positioning rod 13. At the same time, the adjusting block 2112 drives the guide rod 2116 to move on the fixed block 2104 and the connecting block 2100. The guide rod 2116 drives the pressing block 2117 to squeeze the deformed side of the sound beam body 11, which helps the sound beam body 11 to recover and improves the performance.

[0033] In this invention, the adjusting bolt 2115 is rotated on the assembly block 2111, causing the adjusting bolt 2115 to drive the rotating disk 2120 on the movable rod 2119 to rotate on the rotating cavity 2118, so that the adjusting block 2112 moves on the two connecting rods 2110.

[0034] Working principle: The main body 11 of the sound beam deforms on its sides due to humidity and temperature. The slots 2102 on the two U-shaped blocks 2101 are respectively engaged with the two positioning rods 13. The connecting block 2100 is located between the two positioning rods 13. Rotating the adjusting bolt 2115 on the assembly block 2111 causes the adjusting bolt 2115 to drive the rotating disk 2120 on the movable rod 2119 to rotate in the rotating cavity 2118, allowing the adjusting block 2112 to move on the two connecting rods 2110. Under the action of rod 2114, the insertion rod 2108 on the movable block 2107 passes through the display port 2103 and engages with the positioning hole 20 on the positioning rod 13, increasing the stability between the adjustable stabilizing mechanism 21 and the positioning rod 13. At the same time, the adjusting block 2112 drives the guide rod 2116 to move on the fixed block 2104 and the connecting block 2100. The guide rod 2116 drives the pressure block 2117 to press the deformed side of the sound beam body 11, which helps the sound beam body 11 to recover and improve the performance.
