Abstract
A kind of magnetic-inductive device of piano wire, including qin box, string, support bar are sequentially connected, and magnet is provided with below string.The right and left of qin box is installed with support bar, and the left side that qin box is fixed on by support bar of string, the other end of string is fixed on the right of qin box by support bar.A minimum of 1 of string, can at most set 100.Magnet uses strong magnets.Present invention finger keystroke when playing, drive gavel strike piano wire, steel wire in qin to be vibrated in magnetic field, produce the induced current of certain frequency.Different keys is pressed, mallet strike different thicknesses, length, elastic steel wire, the induced current of different frequency is produced, induced current input amplifier, after amplifier amplifies, sends the piano melody of clear magnificence.
Description
Technical field
The present invention relates to a kind of electromagnetic induction performer, relates in particular to one kind and allows piano wire to vibrate production in magnetic field
Raw induced current, a kind of magnetic-inductive device of the amplified piano wire for sending sound.
Background technology
At present, there are the various electronic organs for being shaken with electronics and producing analog music, also have and various amplify again by string sounding
Electrophonic musical instrument, but the music amplified is still not true to nature enough or not pure enough magnificence.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art part, there is provided one kind allows piano wire to vibrate production in magnetic field
Raw induced current, a kind of magnetic-inductive device of the amplified piano wire for sending sound.
The technical solution adopted for the present invention to solve the technical problems is：A kind of magnetic-inductive device of piano wire, including
Qin box, string, support bar are sequentially connected, and magnet is provided with below string.The right and left of qin box is installed with support bar,
One left side that qin box is fixed on by support bar of string, the other end of string are fixed on the right of qin box by support bar.
A minimum of 1 of string, can at most set 100.Magnet uses strong magnets.
The invention has the advantages that the finger keystroke when playing, drives gavel strike piano wire, steel wire in qin to exist
Vibrated in magnetic field, produce the induced current of certain frequency.Press different keys, mallet strike different thicknesses, length, elastic steel
Silk, the induced current of different frequency is produced, induced current input amplifier, after amplifier amplifies, sends the steel of clear magnificence
Qin melody.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure chart of embodiments of the invention one.
In figure：1. qin box, 2. strings, 3. support bars, 4. magnet.
Embodiment
In the embodiment shown in fig. 1, it is provided with qin box（1）, string（2）, support bar（3）, magnet（4）.
Implement a kind of magnetic-inductive device of piano wire of the present invention, including qin box（1）, string（2）, support bar（3）According to
Secondary connection, string（2）Lower section magnet is installed（4）.Qin box（1）The right and left be installed with support bar（3）, string
（2）One pass through support bar（3）It is fixed on qin box（1）The left side, string（2）Other end pass through support bar（3）It is fixed on
Qin box（1）The right.String（2）A minimum of 1, it can at most set 100.Magnet（4）Using strong magnets.
Implement a kind of magnetic-inductive device of piano wire of the present invention, the finger keystroke when playing, drive gavel in qin
Piano wire is hit, steel wire vibrates in magnetic field, produces the induced current of certain frequency.Different keys is pressed, mallet strike is different
Thickness length, elastic steel wire, produce the induced current of different frequency, induced current input amplifier, after amplifier amplifies,
Send the piano melody of clear magnificence.
Implement a kind of magnetic-inductive device of piano wire of the present invention, the place of various musical backgrounds can be used in.This hair
Bright design and making feature is that magnet should use high-intensity magnetic field.Implement the present invention, more steel are equipped with same high-intensity magnetic field
Silk, the different various steel wires of thickness can be used, to obtain different musical tones.The effect of the present invention is compared with electronic organ, sound
Sound is more pure, is good electromagnetic induction performer.
Implement the present invention, effect is fine.
