Abstract

The utility model discloses a bridge of stringed musical instrument with a pick-up, comprising a sheet-shaped bridge body which is fixed between the instrument body and the strings of the stringed musical instrument when used. The bridge body is provided with a rectangular slotted hole in horizontal direction, and the slotted hole is inlaid with piezoelectric pick-up pieces or blocks the electrodes of which are connected to an audio-frequency socket. The bridge of the utility model can be used for various stringed musical instruments, and has the advantages of preferred pick-up effect and large sound volume. The user can play the musical instrument alone without electricity, and can transfer high-fidelity audio signals to the sound equipment in order to realize electronic play.

Description

The bridge horse that is used for stringed musical instrument

Technical field

The utility model relates to the musical instrument field, particularly a kind of bridge horse that is used on the stringed musical instrument.

Background technology

As everyone knows, the sounding of stringed musical instrument is to be produced by the vibration of string.The vibration of string passes to the qin body by the bridge horse, and the end by the qin body and face soundboard will vibrate formed acoustic reflection and form sound wave at the resonant tank internal resonance again.

Traditional stringed musical instrument (as violin) is made of the device of qin body, resonant tank, string, constant chord and the bridge horse that is located between the qin body chord.Traditional stringed musical instrument does not have sound pick up equipment, and sound is smaller, influences playing effect.Chinese patent (ZL01271476.3) discloses a kind of " band music hall sound field effect electronic violin " that I am invented, the characteristics of this stringed musical instrument are not establish resonant tank, a piezoelectricity pickup rod that is pressed between bridge horse and the qin body is arranged on it, piezoelectricity pickup rod can pass to electronic circuit with the vibration signal of string, forms sound signal and output to earphone or stereo set after amplifying.This shows that the bridge horse is the critical piece that influences the stringed musical instrument pronunciation.The shortcoming of prior art is: or do not have the electronics sound pick up equipment, and sound is little, can not play by electronics, can't realize that high-fidelity expands, playback; Though be that the electronics sound pick up equipment is arranged, there is not resonant tank, non-ly can not play by the electronics public address equipment, and unreasonable structure: the electronics sound pick up equipment is crimped between the face soundboard of qin body and the bridge horse and influences its phonosensitive, and pickup effect is poor.

Summary of the invention

Task of the present utility model be to design a kind of can with the novel bridge horse of various stringed musical instrument adapteds, be furnished with the stringed musical instrument of this bridge horse, both can equally play to common musical instrument, but electronics is played again, and does not influence the vibration of resonant tank, and pickup effect is good, undistorted, loud, adapted is convenient.

The technical solution of the utility model is as follows:

A kind of bridge horse that is used for stringed musical instrument, comprise the bridge horse body between the qin body chord that is fixed on stringed musical instrument when using, it is characterized in that on described body, being provided with square slotted eye, in slotted eye, be inlaid with piezoelectricity pickup sheet or piece, be connected with an audio socket with the electrode of piezoelectricity pickup sheet or piece.

Further improve and be that described audio socket is fixed on the base, base can be connected on the qin body.

Described body is made of upper and lower two parts, and top is similar to rectangular parallelepiped, and the bottom is that described piezoelectricity pickup sheet or piece are embedded in the bottom of rectangular parallelepiped with its leg of propping.

Because the bridge at the utility model is inlaid with piezoelectricity pickup sheet or piece at once, it is installed on the qin body, and under the situation that does not influence tonequality, the vibration of string on the one hand can be delivered to resonant tank on the qin body through bridge horse and qin body, produce bigger sound, realize playing separately; The vibration signal of string can produce the electric signal of high-fidelity on piezoelectricity pickup sheet or piece on the other hand, electric signal is exported to external acoustics through audio socket can carry out electroacoustic processing and broadcast to it, neither influences the vibration of resonant tank, and pickup effect is good again, undistorted, adapted is convenient.

Fig. 2 is that the utility model is installed in the synoptic diagram on the stringed musical instrument.

Embodiment

A kind of bridge horse that is used for stringed musical instrument comprises a sheet bridge horse body 3, and it is to be formed by timber section, is vertically fixed on during use between the face soundboard chord 2 of qin body 1 of various stringed musical instruments.Bridge horse body 3 is made of upper and lower two parts, top is similar to rectangular parallelepiped 9 (arched top), the bottom is with its leg of propping 8, body 3 bottom along continuous straight runs have rectangle slotted eye 4, in slotted eye 4, be inlaid with piezoelectricity pickup sheet 5, be connected with an audio socket 6 with the electrode of piezoelectricity pickup sheet 5, audio socket 6 is fixed on the base 7, and base 7 is connected on the limit of qin body 1.

Using method is: the bridge horse is fixed on the qin body 1 of stringed musical instrument (is example with the violin), when need not electronics play, when amplifying, electronic equipments such as audio socket 6 and sound equipment are not connected, and only depend on the resonant tank sounding of stringed musical instrument to get final product; Need electronics to play, when amplifying, audio socket 6 and stereo set are joined.In the time of resonant tank 8 sounding, stereo set also amplifies, broadcasts this voice signal simultaneously.

Piezoelectricity pickup sheet 5 is embedded in the set rectangle slotted eye 4 of body 3 bottom along continuous straight runs, is positioned at the neutral gear of leg 8, and it is little that piezoelectricity pickup sheet 5 is influenced by external force, and pickup effect is better.

Claims

1, a kind of bridge horse that is used for stringed musical instrument, comprise the bridge horse body (3) between qin body (1) chord (2) that is fixed on stringed musical instrument when using, it is characterized in that on described body (3), being provided with square slotted eye (4), in slotted eye (4), be inlaid with piezoelectricity pickup sheet or piece (5), be connected with an audio socket (6) with the electrode of piezoelectricity pickup sheet or piece (5).

2, according to the described bridge horse of claim 1, it is characterized in that described audio socket (6) is fixed on the base (7), base (7) can be connected on the qin body (1).
