Description

Technical Field

[0001] The utility model belongs to the field of electric guitars, and more specifically relates to an electric guitar with a synchronized tremolo bridge. Background Art

[0002] An electric guitar is a stringed instrument that uses the principle of electromagnetism. When the magnetized guitar strings vibrate, they drive the magnetic flux in the coil on the pickup to change, thereby generating electric currents of different frequencies, and the electric signals are restored and emitted through an electronic speaker.

[0003] In the existing double tremolo electric guitars, when in use, to achieve the synchronized tremolo effect, the tremolo bar needs to be pressed. The tremolo bar drives the tremolo bridge, and under the action of the tension spring, the tension of the strings changes. Then, the strings are played with fingers to produce the tremolo effect. During the performance, the tension of the tension spring is particularly important. An appropriate tension of the tension spring can ensure that the strings are stably fixed on the bridge, and at the same time, it can also maintain an appropriate tension, making the sound emitted by the strings clearer and fuller. The performer can adjust the tension of the tension spring according to personal preferences and performance needs.

[0004] In the prior art, as Figure 1 shown, when the performer adjusts the tension of the tension spring, the tension of the tension spring can only be adjusted by rotating the screw with a screwdriver. Although in the prior art, corresponding holes are opened on the protective plate for the screwdriver to extend in, facilitating the performer to adjust the tension of the tension spring, but still tools are needed to achieve the adjustment during the adjustment. Summary of the Utility Model

[0036] The working process and beneficial effects of the present utility model are as follows:

[0037] When it is necessary to adjust the tension of the extension spring 404, by rotating the adjusting nut 701, the adjusting nut 701 drives the rotating shaft and the main gear 702 to rotate. The main gear 702 drives the driven gear 703 meshing with it. The two driven gears 703 drive the nut 704 to rotate. While rotating, the threaded rod 705 rotates on the side wall of the connecting frame 403, and then drives the connecting frame 403 and the extension spring 404 suspended on the connecting frame 403 to move, so as to realize the adjustment of the tension of the extension spring 404, solving the problem that in the prior art, tools are needed to adjust the extension spring 404, making the adjustment more convenient and fast, and at the same time reducing the difficulty for novice players to adjust the extension spring 404.

[0038] When the position adjusted by the adjusting nut 701 still cannot meet the playing preferences of the performer, by rotating the adjusting bolt 10, the adjusting bolt 10 drives the second suspension column 12 and the third suspension column 13 threadedly connected to it to move, making the tension of the extension spring 404 tighter to meet the preferences of the performer. Through the arc-shaped grooves 14 provided on the side walls of the first suspension column 11, the second suspension column 12 and the third suspension column 13, it is prevented that the extension spring 404 slips off when sleeved on the outer walls of the first suspension column 11, the second suspension column 12 and the third suspension column 13.

[0039] The setting of the reinforcing rib 15 improves the connection strength between the fixing part 8 and the suspension part 9, avoiding the problem that the fixing part 8 and the suspension part 9 are broken after long-term use. The protective cover 16 and the protective cap 17 play a protective role for the components in the installation groove 3 and the rectangular groove 5, extending the service life of the components. The setting of the knurling increases the friction force between the adjusting nut 701 and the finger, preventing the phenomenon of hand slipping when rotating the adjusting nut 701. The setting of the protective strip 18 can protect the edge of the piano body 1, avoiding scratches caused by the collision and friction between the edge of the piano body 1 and other objects.

[0040] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention shall be included in the protection scope of the present invention.
