Description
Technical Field
The invention belongs to the technical field of musical instruments, and particularly relates to an active piezoelectric sound pickup special for a guqin.
Background
The guqin is the oldest and purest traditional Chinese musical instrument, has a long history of over 3000 years, is a representative of traditional Chinese music culture, and is a treasure in the Chinese culture. Because the guqin is mostly the preparation of old tong plank and old fir plank, and the plate body of musical instrument is thick and solid, and the resonance chamber is small, and the second-order resonance is not easy, so the volume of sending when playing is very little, (according to the actual measurement, the acoustic pressure when seven strings of guqin played is only between 50 ~ 60 decibels, does not exceed 60dB), so amplify the tone color of "simple and unsophisticated, agile, deep, artistic conception cavity" when this kind of playing of guqin was played and is particularly important. The traditional means of today is to adopt the electric capacity microphone to pick up sound, and this kind of pickup mode receives pickup position, distance, regional influence very big, and the transaudient gain is little, wants big volume radio reception to enlarge, very easily produces the feedback phenomenon (squeal phenomenon and low frequency buzz), and the pickup mode of small-size electric capacity microphone clamp in guqin sound hole position causes "cavity sound" serious, and tone quality is muddy. The most delicate overtones of the guqin and the lingering sounds of the strings in slight vibration cannot be picked up, and the noise of the surrounding environment is easily picked up due to the large pickup range of the capacitor microphone, so that the expanded sound becomes unclean due to the impurity of the environmental noise.
Therefore, the key for solving the problems is to develop the pickup equipment which is convenient to use, small in bottom noise, sensitive in pickup, fast in transient response and capable of really restoring the original sound of the guqin.
Disclosure of Invention
The invention aims to provide the special active piezoelectric pickup for the guqin, which has the advantages of convenient use, small bottom noise, sensitive pickup and fast transient response.
The invention is realized by the following technical scheme: including adapter base, piezoelectricity response strip support, piezoelectricity response strip and string pillow, the both ends of piezoelectricity response strip support set up on the adapter base through altitude mixture control pole detachably respectively, and altitude mixture control pole is connected with piezoelectricity response strip support, the equal screw-thread fit of adapter base, the rear side of piezoelectricity response strip support is provided with the mounting groove, and the front side sets up the musical instrument groove, sets up piezoelectricity response strip in the mounting groove, is provided with the musical instrument string pillow at the mounting groove top, and the string pillow is fixed piezoelectricity response strip in the mounting groove, arbitrary end of piezoelectricity response strip sets up the signal output plug.
The invention has the beneficial effects that: the device is simple and quick to install, small and convenient to carry, can be installed without loosing strings, can be perfectly combined with the body of the Guqin, does not damage the body, can acquire the maximum resonance amplitude and the frequency of the body, and quickly responds to pickup transient state; the device can pick up the sound generated by the simultaneous vibration of the strings, the bridge and all parts of the piano plate, can also capture the fine vibration of the strings, has high pickup efficiency, strong adjustability, no distortion, no bottom noise, no squealing feedback and high sound transmission gain, and can highly restore the sound of the guqin; on the other hand, the device can also be used on various existing stringed instruments, and can be used for sound pickup processing only by being arranged at corresponding positions on various stringed instruments.
