Description

Technical Field

[0001] The utility model relates to the technical field of neck curvature adjustment, in particular to a neck curvature adjustment device for an electric guitar. Background Art

[0002] The electric guitar is an electroacoustic plucked string instrument widely used in a variety of musical styles. It produces sound through the principle of electromagnetism, that is, the mechanical vibration on the strings is converted into electrical signals by using a pickup. After amplification and processing, these electrical signals are converted into sound signals through a speaker to produce sound. The electric guitar is usually composed of a body, a neck, a headstock, pegs, pickups, a volume knob, and a tone knob. Among them, the neck will also form different curvatures due to different needs, and the formation of its curvature requires a corresponding curvature adjustment device to cooperate. The neck curvature adjustment devices on the market are mostly composed of a lower load wheel and an upper pressing wheel, and the lower load wheel is mostly designed in two ways, so that the distance between the two can be adjusted when the curvature adjustment needs are different. The current adjustment is mostly achieved by simply changing different mounting grooves, which will cause the lower load wheel to be stored separately during overall transportation, so as to avoid loss during handling and transportation, and then taken out and placed again during later use, which will increase the cumbersomeness of use, and the stability during use is also average. For this reason, we provide an electric guitar neck curvature adjustment device. Utility Model Content
