Description
Technical field
Sound device is opened the present invention relates to one kind more particularly to a kind of urheen opens sound device and its fixed device, opens sound method.
Background technique
It is said that someone once purchased one more than 5000 yuan of redwood urheen, unexpectedly there are no one more than 500 urheen sound quality is good,
Manufacturer replies new urheen not yet " opening sound "." the opening sound " of urheen is the equal of " adjustment " in machinery, and needs are being purchased
After urheen, artificial examination draws the time of or so half a year could be by urheen " opening sound ", if but being intended to that urheen is allowed to beat process middle pitch in drawing
Matter is more and more pleasing to the ear and settles out, this process at least wants two to triennium, and which results in consumers in purchase urheen
When, can not judge the texture of urheen according to the sound quality of urheen, therefore it is necessary to produce it is a kind of efficiently, and can volume production urheen
It is very necessary to open sound device, so that urheen producer can carry out open sound to urheen after having produced urheen, to make consumer
When buying urheen, the value of urheen can be judged by the sound quality of urheen.
Chinese Patent Application No. provides a kind of guitar and opens sound mounted maintenance equipment for 201310392101.3 patent of invention, uses
Audio frequency vibration generator cell operation makes guitar qin body do slight vibration by defined rhythm, and the small modulus of through a long time vibrates adjustment, can
So that each component combination of guitar is finally close to stress equilibrium.This is a kind of good method, still, audio frequency vibration generator unit and control
The integrated structure of drive circuit board processed, be using battery drive, power is too small, but be audible audio, have noise, efficiency
It is very low.
To solve the above-mentioned problems, Chinese Patent Application No. provides a kind of urheen for 201710145230 patent of invention
Ultrasonic wave opens sound machine, this, which is opened, is equipped with lifting pressure head above the workbench of sound machine, going up and down below pressure head has ultrasonic oscillator, ultrasound
Wave oscillator is connected with the output end of supersonic generator, and Erhu music instrument skin is being pressed against below ultrasonic oscillator.Its working principle is that:
Ultrasonic energy from supersonic generator is converted into mechanical oscillation by ultrasonic oscillator, is simulated to the bridge position of qin skin
The pressure of string, then to the mechanical vibration that qin skin is strengthened, improve the stress distribution in the intradermal portion of qin, improve the pronunciation of qin skin
Sound quality, achieve the purpose that give urheen " opening sound ".
Above-mentioned is and to pass mechanical oscillation by the way that ultrasonic energy is converted into mechanical oscillation and pass to qin skin by bridge.
Although the patent is able to achieve quickly opens sound for urheen, but since it is the mechanical energy by the way that ultrasonic energy to be converted to bridge and is applied
It is added on qin skin, therefore it is opened audio fruit and is extremely difficult to carry out out the effect of sound by pulling urheen.
Therefore, develop it is a kind of can imitate completely manually play er hu to urheen carry out out sound to open sound device very necessary.
