Description

Electric ancient musical instrument Technical Field The utility model relates to the technical field of national musical instruments, in particular to an electric ancient musical instrument. Background Ancient musical instruments are used as Chinese traditional musical instruments, and have elegant and long-lasting tone, but have obvious sound amplifying problems in modern performance environments. The traditional ancient musical instrument sounds weak, and is easy to be covered by other musical instruments especially in the ensemble or large-scale occasion. At present, a common sound amplifying scheme relies on an external microphone to pick up sound, but the mode is easy to be interfered by environmental noise, and tone color distortion, low-frequency missing or high-frequency harshness are caused after sound amplifying due to mismatching of resonance characteristics of the microphone and a musical instrument body, so that original charm of the old musical instrument is lost. In order to solve the above problems, some technologies attempt to install an electromagnetic pickup or a contact microphone inside a body, but still have problems such as insufficient signal sensitivity, narrow frequency response range, or damage to the body structure due to installation. In addition, the vibration characteristics of different sections (such as a dragon to a badge) of the Guqin are obviously different, and the tone color of the Guqin is difficult to be uniformly captured by a single pickup, so that the tone quality reduction effect is further limited. Disclosure of utility model The utility model provides an electric ancient organ, which solves the core problems of tone and color distortion, insufficient dynamic range and the like in the sound amplification of the ancient organ in a physical level through acoustic partitioning, electromechanical coupling optimization and multichannel processing technology, and has high fidelity and performance adaptability. The utility model provides an electric ancient musical instrument, which comprises a musical instrument panel, a base plate, a piezoelectric pickup piece and a pickup interface, wherein a plurality of strings are arranged on the top of the musical instrument panel, a plurality of logo positions are arranged on the base plate corresponding to the strings along the length direction, the base plate is arranged at the bottom of the musical instrument panel, a musical instrument abdomen is arranged between the base plate and the musical instrument panel, the base plate is provided with a through dragon pool and a phoenix biogas corresponding to the musical instrument abdomen, the piezoelectric pickup piece is fixedly arranged in the musical instrument abdomen, and the pickup interface is fixedly arranged at the bottom of the base plate and is electrically connected with the piezoelectric pickup piece. Preferably, the piezoelectric pickup pieces are arranged in a plurality, and are respectively fixed at the bottom of the piano panel and correspond to the logo positions. Preferably, the bottom of the musical instrument panel is respectively provided with a circular groove corresponding to each logo, and each piezoelectric pickup piece is respectively embedded in the middle of the corresponding circular groove. Preferably, each circular groove is circumferentially provided with a step, and each piezoelectric pickup piece is abutted against the step through the peripheral edge. Preferably, the sound pickup interfaces are arranged in a plurality and are electrically connected with the corresponding piezoelectric sound pickup sheets, and the sound mixing console is electrically connected with the corresponding piezoelectric sound pickup sheets through the sound pickup interfaces. The utility model has the beneficial effects that the piezoelectric pickup is arranged in the specific vibration area of the panel to directly collect the mechanical vibration signals of the strings and the panel, thereby avoiding the interference of environmental noise. The high impedance characteristic of the piezoelectric sheet is highly matched with the low-frequency vibration of the ancient musical instrument, so that the thickness and overtone level of the original tone can be reserved. The multi-piezoelectric pickup piece is arranged to cover the organ body in a partitioned mode, and the tuning console is connected to independently adjust gain, frequency response and phase parameters of each area, so that fine tone color regulation and control aiming at different playing techniques are achieved, and finally, a high-fidelity customizable electroacoustic solution of the ancient organ is achieved. The technology not only overcomes the defect of tone degradation of the traditional sound amplifying mode, but also provides more flexible technical support for modern playing, recording and stage application of the Guqin.
