CN203038657U - Electric guzheng bamboo cane and guide sleeve structure device - Google Patents

Abstract

The utility model relates to a musical instrument. The musical instrument comprises strings, a plurality of bamboo canes contacting with each string and disposed below the strings, and a piezoelectric cable contacting with the bamboo canes and disposed between the bamboo canes and a qin crossie, and elastic object guide sleeves disposed on two sides of the bamboo canes. Lower end surfaces of the bamboo canes are aligned to the piezoelectric cable. The utility model provides an electric guzheng which comprehensively acquires audio signals generated by vibration of the strings and overcomes problems of crosstalk, sound mixing, and noise exist in an existing electric guzheng, and the electric guzheng can play wonderful music.

Description

A kind of electric Zheng bamboo bar and orienting sleeve constructional device

Technical field

The utility model relates to a kind of musical instrument, relates in particular to a kind of electric Zheng bamboo bar and orienting sleeve constructional device.

Background technology

Zheng is as a kind of traditional musical instrument, and is very popular with its tonequality grace, and mainly there is following defective in existing electric Zheng sensor:

1) present its sensor of electric Zheng mostly adopts piezoelectric cable, and its piezoelectric cable is preset under the preceding Yue Shanzhu bar, on the nut wood, and the three sticks with glue agent and is solidified as a whole; Because piezoelectric cable is longer, in the gluing process of tackifier, since the elastic deformation amount of each piezoelectric cable is different and cementing agent in solidification process, piezoelectric cable deflection everywhere is also inconsistent, cause each contact site of bamboo bar and piezoelectric cable not press and touch reliably, make piezoelectric cable be difficult to basic announcement and the overtone of 21 strings are picked up comprehensively, have cross-talk and audio mixing problem simultaneously, cause audio-frequency harmonic distortion; 2) the existing bamboo bar that contacts with piezoelectric cable is segmentation structure, and in pressing the string playing procedure leftward, bamboo bar generation fine motion and cause the generation of noise signals makes audio-frequency harmonic distortion.

The utility model content

The utility model is at above-mentioned defective, and purpose is to provide a kind of sound signal that can comprehensively the string vibration be produced pick up, and can overcome present electric Zheng and have cross-talk, audio mixing and souffle problem, makes it produce the electric Zheng of beautiful music.

The technical solution adopted in the utility model is for this reason: comprise string, be arranged on the some bamboo bars that contact with corresponding each string under the string, establish between bamboo bar and the nut wood with the bamboo bar and press the piezoelectric cable that touches, the elastomeric objects orienting sleeve is established in described bamboo bar both sides, and bamboo bar lower surface is over against piezoelectric cable.

Described bamboo bar is some separate component structures.

Described device is applicable to electric seven-stringed plucked instrument in some ways similar to the zither.

The utility model has the advantages that: the utility model is established the elastomeric objects orienting sleeve in the both sides of independent bamboo bar, piezoelectric cable is placed in the nut wood groove, and independent bamboo bar lower end is over against piezoelectric cable; When this version moves downward under the compacting of string tension force when independent bamboo bar, because the existence of elastomeric objects orienting sleeve, each independent bamboo bar and corresponding piezoelectric cable all can closely be pressed tactile, basic announcement and overtone vibration signal that string is produced are picked up by piezoelectric cable comprehensively, make tone color reach optimum efficiency.

Description of drawings

Fig. 1 is structural representation of the present utility model.

1 is that string, 2 is that bamboo bar, 3 is that piezoelectric cable, 4 is that Qian Yue mountain nut wood, 5 is that elastomeric objects orienting sleeve, 6 is peg among the figure.

Embodiment

The utility model comprises string 1, is arranged on string 1 time and the tactile some bamboo bars 2 of corresponding each string 1 pressure, establish between bamboo bar 2 and the nut wood 4 with bamboo bar 2 and press the piezoelectric cable 3 that touches, establish elastomeric objects orienting sleeve 5 around each bamboo bar 2, bamboo bar 2 lower surfaces are over against piezoelectric cable 3.

Bamboo bar 2 lower surfaces are and tight pressure of piezoelectric cable 3 formation touched, and bamboo bar 2 is the independent split type structure.

String 1 of the present utility model tightens up with tuning on peg 6.

Elastomeric objects orienting sleeve 5 of the present utility model can be elasticity things such as silica gel plate, when insertion bamboo bar 2 presses down, the position that elastomeric objects orienting sleeve 5 contacts with bamboo bar 2 is because the effect of power, the silica gel plate of bamboo bar both sides protrudes to both sides, naturally form " mouth " font state, make the bamboo bar that a good stability be arranged, and make sensor can independently receive certain root vibrations of strings signal, and can not make contiguous and even a lot of strings produce resonance cross-talk, audio mixing and souffle problem, guarantee that tonequality reaches optimum efficiency.

Claims (3)

1. an electric Zheng bamboo bar and orienting sleeve constructional device, comprise string, be arranged under the string and the tactile some bamboo bars of corresponding each string pressure, establish between bamboo bar and the nut wood with the bamboo bar and press the piezoelectric cable that touches, it is characterized in that, the elastomeric objects orienting sleeve is established in described bamboo bar both sides, and bamboo bar lower surface is over against piezoelectric cable.

2. a kind of electric Zheng bamboo bar according to claim 1 and orienting sleeve constructional device is characterized in that, described bamboo bar is some separate component structures.

3. one kind as claim 1 or described electric Zheng bamboo bar and orienting sleeve constructional device, it is characterized in that described device is applicable to electric seven-stringed plucked instrument in some ways similar to the zither.
