Technical field
It is a kind of towards exempt from draw wheat microphone master controller and shaft between scaling method belong to vocal music and music teaching
Field.
Background technology
Singing is the entertainment selection that many people enjoy a lot.However, singing has a lot of specialized skills, including microphone makes
With these skills, which are laymans, to be grasped.
For example, drawing wheat skill, when exactly singing some long, Mike is pulled to be gradually distance from oral area, and then obtain a kind of spy
Different music effect.Time, distance, Mike's movement speed are all very important skill, and amateur singer is difficult to grasp to draw wheat
Skill.This will restrict the artistic effect of singing.
Invention content
It draws wheat skill in order to solve the problems, such as that amateur singer is difficult to grasp and influences singing effect, the present invention devises one
Kind exempt to draw wheat microphone, the effect of wheat is drawn without drawing wheat that can realize, and effect same time, distance, movement speed are accurate
Drawing wheat it is almost the same, effectively improve the artistic effect of singing.
The object of the present invention is achieved like this：
One kind exempt from draw wheat microphone, including acousto-optic modulator, light intensity attenuation system, photoelectric converter, sound transducer, with
And master controller；
The acousto-optic modulator and photoelectric converter are arranged on same straight line, and light intensity attenuation system is arranged in acousto-optic
Among modulator and photoelectric converter；
The input terminal of the output end connection master controller of the sound transducer, the output end connection light intensity of controller decline
Subtract system.
It is above-mentioned to exempt to draw wheat microphone, the light intensity attenuation system to include shaft and multiple attenuation ratios for being distributed in shaft
The different attenuator of example；Main controller controls shaft rotates.
It is above-mentioned to exempt to draw wheat microphone, including a vacuum chamber, light intensity attenuation system, photoelectric converter and master controller
It is arranged in vacuum chamber；Acousto-optic modulator and sound transducer are arranged on vacuum chamber boundary.
Exempt to draw wheat microphone, the scaling method between master controller and shaft as follows above：
Step a, the rule-of-thumb relation of intensity of sound Q, frequency f and the t that holds time are established；Wherein, intensity of sound Q is
Dependent variable, frequency f and the t that holds time are independent variable；
Step b, the functional relation of intensity of sound Q and light intensity I are demarcated；
Step c, the functional relation of light intensity I and shaft rotary corner α are demarcated；
Step d, the functional relation of frequency f, hold time t and corner α are established；Wherein, corner α is dependent variable, frequency
The rate f and t that holds time is independent variable.
Rule-of-thumb relation described in step a, for multiple people obtain at certain intensity of sound Q, frequency f, hold time t's
Average value.
Exempt from draw wheat implementation method be：
Voice signal is converted to optical signal by acousto-optic modulator, after light intensity attenuation system attenuation, by opto-electronic conversion
Device is converted to electric signal；Meanwhile sound transducer acquires sound frequency information, and give master controller processing, master controller root
According to the intensity Q of frequency f sound, and the t that holds time, the angle [alpha] of shaft is adjusted.
Advantageous effect：
The first, since acousto-optic modulator and photoelectric converter are arranged on same straight line, the setting of light intensity attenuation system exists
Among acousto-optic modulator and photoelectric converter；It therefore can be while not changing the output of acousto-optic modulator sound, by adjusting light
The attenuation ratio of strong attenuation factor is realized to change the output signal of photoelectric converter and draws wheat effect；
The second, the input terminal of the output end connection master controller of sound transducer, the output end connection light intensity of controller decline
Subtract system；This design can detect holding time for certain frequency acoustic by sound transducer, and then obtain required for drawing wheat
Attenuation ratio；
Two above technical solution is combined, and judges that sound transducer acquires frequency and the maintenance of sound according to master controller
Time adjusts the attenuation ratio of light intensity attenuation system, and then changes the intensity of photoelectric converter output signal, realizes and draws wheat effect
Fruit effectively improves the artistic effect of singing.
