Description
Technical field
One is exempted to draw wheat mike to belong to vocal music and music teaching field.
Background technology
Singing is the entertainment selection that a lot of people enjoys a lot.But, sing and have a lot of specialized skills, including the use of mike,
These skills are that layman can not grasp.
Such as, draw wheat skill, it is simply that when singing certain long, pull Mike to be gradually distance from oral area, so obtain a kind of special
Music effect.Time, distance, Mike's translational speed are all very important skills, and amateur singer is difficult to grasp and draws wheat skill.
This will restrict the artistic effect of singing.
Summary of the invention
Being difficult to grasp draw wheat skill to affect the problem of singing effect to solve amateur singer, the present invention devises one and exempts to draw
Wheat mike, it is not necessary to draw wheat just can realize drawing the effect of wheat, and effect same time, distance, translational speed draw wheat accurately
Almost identical, it is effectively improved the artistic effect of singing.
The object of the present invention is achieved like this:
One is exempted to draw wheat mike, including acousto-optic modulator, light intensity attenuation system, optical-electrical converter, sound transducer and
Master controller；
Described acousto-optic modulator and optical-electrical converter are arranged on same straight line, and light intensity attenuation system is arranged on acousto-optic modulator
In the middle of optical-electrical converter；
The outfan of described sound transducer connects the input of master controller, and the outfan of controller connects light intensity attenuation system.
Above-mentioned exempting to draw wheat mike, described light intensity attenuation system includes that rotating shaft and the multiple attenuation ratios being distributed in rotating shaft are each the most not
Identical attenuator；Main controller controls axis of rotation.
Above-mentioned exempting from draws wheat mike, and including a vacuum chamber, light intensity attenuation system, optical-electrical converter and master controller are arranged
In vacuum chamber；Acousto-optic modulator and sound transducer are arranged on vacuum chamber border.
More than exempting to draw wheat mike, the scaling method between master controller and rotating shaft is as follows:
Step a, set up intensity of sound Q, frequency f and the rule-of-thumb relation of the t that holds time；Wherein, intensity of sound Q is
Dependent variable, frequency f and the t that holds time are independent variable；
Step b, demarcation intensity of sound Q and the functional relation of light intensity I；
Step c, demarcation light intensity I and the functional relation of shaft rotary corner α；
Step d, set up frequency f, hold time t and the functional relation of corner α；Wherein, corner α is dependent variable,
Frequency f and the t that holds time are independent variable.
Rule-of-thumb relation described in step a, for many individuals obtain under certain intensity of sound Q, frequency f, the t's that holds time is flat
Average.
The implementation method exempting to draw wheat is:
Acoustical signal is converted to optical signal by acousto-optic modulator, then after light intensity attenuation system attenuation, changes optical-electrical converter
For the signal of telecommunication；Meanwhile, sound transducer gathers sound frequency information, and gives master controller process, and master controller is according to this frequency
The intensity Q of rate f sound, and the t that holds time, adjust the angle [alpha] of rotating shaft.
Beneficial effect:
The first, being arranged on same straight line due to acousto-optic modulator and optical-electrical converter, light intensity attenuation system is arranged on acousto-optic and adjusts
In the middle of device processed and optical-electrical converter；Therefore can be while not changing acousto-optic modulator voice output, by adjusting light intensity attenuation system
The attenuation ratio of system, changes the output signal of optical-electrical converter, it is achieved draw wheat effect；
The second, the outfan of sound transducer connects the input of master controller, and the outfan of controller connects light intensity attenuation system；
This design, it is possible to detect holding time of certain frequency acoustic by sound transducer, and then obtain drawing the attenuation ratio required for wheat
Example；
Two above technical scheme combines, and judges that sound transducer gathers the frequency of sound and holds time according to master controller,
Adjust the attenuation ratio of light intensity attenuation system, and then change the intensity of optical-electrical converter output signal, it is achieved draw wheat effect, effectively
Improve the artistic effect sung.
