CN203588664U - Electric Erhu (a kind of Chinese musical instrument) - Google Patents

Abstract

The utility model relates to an electric Erhu (a kind of Chinese musical instrument). The electric Erhu comprise an Erhu board (1), a piezoelectric cable (2) and a binding device which binds the piezoelectric cable (2) on the Erhu board (1). An elastic piece (8) is arranged between the piezoelectric cable (2) and the Erhu board (1). The electric Erhu is advantaged in that the elastic piece is arranged between the binding device and the piezoelectric cable, and thus the elastic piece can enable the Erhu board and the piezoelectric cable to maintain the optimal press fit state by means of the elastic pressure of the elastic piece, audio frequency electric signals which may be strong, weak, or subtle can be fully captured by the piezoelectric cable, and the electric Erhu is better than a traditional Erhu in terms of tone quality, timber and comprehensive application effect; and the outer side of the Erhu board is additionally provided with an artificial python skin to keep the element of the traditional Erhu.

Description

A kind of electric urheen

Technical field

The utility model relates to a kind of electric urheen, belongs to musical instrument electroacoustic techniques field.

Background technology

Current electric urheen sensor device is substantially inner in bridge or in bridge bottom, said apparatus all can not truly reduce to the soft and graceful tone color of urheen, and its product can not get market to be approved widely, needs further to be improved.

Utility model content

The utility model is for above-mentioned defect, and object is to provide a kind of electric urheen electric urheen that soft and graceful tone color can fully truly be reduced.

The technical solution adopted in the utility model is for this reason: the utility model includes Erhu music instrument plate (1), piezoelectric cable (2), and piezoelectric cable (2) is bundled in to the binding device on Erhu music instrument plate (1), between piezoelectric cable (2) and Erhu music instrument plate (1), elasticity thing (8) is set.

Described binding device is rope band, tinsel (9), between described rope band, tinsel (9) and piezoelectric cable (2), establishes elasticity thing (8).

Described binding device is U-shaped buckle (3), and Erhu music instrument plate (1), piezoelectric cable (2), elasticity thing (8) are successively set in U-shaped buckle (3) from outside to inside.

Erhu music instrument plate (1) both sides pad pasting, artificial boa skin can be sticked in its outside.

The utility model has the advantages that: 1) the utility model is established elasticity thing between binding device and piezoelectric cable, like this under the effect of elasticity thing elastic pressure, can make piezoelectric cable and qin plate can keep all the time best pressure to touch state, thereby the trickle audio electrical signal of the power that makes string generation of vibration fully picks up to piezoelectric cable, make to be better than traditional urheen in the tonequality of electric urheen and tone color and integrated application effect; 2) Erhu music instrument plate outside adds artificial boa skin, to keep the element of traditional urheen.

Accompanying drawing explanation

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

Fig. 2 is side structure schematic diagram of the present utility model.

Fig. 3 is that the utility model sensor is bundled in the structural representation on rope band, tinsel.

Fig. 4 is the U-shaped snap-fitted schematic cross-section of the utility model.

In figure, 1 is that Erhu music instrument plate, 2 is that piezoelectric cable, 3 is that U-shaped buckle, 4 is that piezoelectric cable electrical signal, 5 is that urheen bridge, 6 is that urheen string, 7 is that two-stringed piano drum, 8 is that elasticity thing, 9 is rope band, tinsel.

Embodiment

The utility model includes piezoelectric cable 2, urheen bridge 5, urheen string 6, two-stringed piano drum 7 etc.

Piezoelectric cable 2 of the present utility model is arranged on Erhu music instrument plate 1, and artificial boa skin enrichment effect can be pasted in the outside of Erhu music instrument plate 1.

The utility model can be by binding devices such as U-shaped buckle 3 or rope band, tinsels 9 by piezoelectric cable 2 and 1 binding of Erhu music instrument plate, and establish elasticity thing 8 between binding device and piezoelectric cable 2, so that piezoelectric cable 2 and Erhu music instrument plate 1 can keep best pressure to touch state all the time, thereby the trickle audio electrical signal of power of urheen string 6 generation of vibrations is fully picked up to piezoelectric cable 2, and by 4 outputs of piezoelectric cable electrical signal, through power amplifier, amplify, the soft and graceful tone color of urheen can truly be reduced.

Erhu music instrument plate 1 of the present utility model can be hexagon, circle or oval etc.

Claims (4)
