Description
Technical field
The utility model belongs to screen vibration field, and in particular to a kind of vibrating mechanism and a kind of screen vibrated except speckle
Frame.
Background technique
The development advanced by leaps and bounds with television technology, using advanced crystallo-luminescence, optical fiber transmit " laser light source " with
By means of its light source colour purity is high, the advantage that light efficiency is high, the service life is long, gradually replaces existing xenon source, captures motion picture projection market,
" the projection light source " most popular as current digital movie circle.
But " laser light source " has the defect that can not ignore, i.e. laser speckle phenomenon: due to the coherence of pure laser,
So that its " laser light source ", which is radiated in object (such as screen), can generate a kind of " bright back light credit of the multicolored graininess of random distribution
Scatter hot spot point " light interference, cause picture image quality unintelligible, to influence viewing effect.
Therefore, each projector manufacturer can all be equipped with laser speckle vibration on the projection equipment of application laser light source both at home and abroad
Elimination mechanism, principle be screen vibration to certain frequency when people would not visually perceive speckle, common removing measure
Have following several:
1. magnet vibratory drilling method: attaching magnetisable coating at the screen back side, vibrated by vibration electromagnet.
If Patent No. " 201711364294.6 ", patent name are the special of " a kind of vibration screen for eliminating laser speckle "
Benefit, it discloses " have the magnetisable coating being made of magnetic material in the backside coating of screen, the position close to the screen back side is installed
There is vibration electromagnet, vibration electromagnet is corresponding with the vibration center of magnetisable coating, and the side of taut curtain frame is provided with vibration control
Device processed, vibration electromagnet be connected with vibrating controller by conducting wire ", " screen by tighten rope it is tight on taut curtain frame, pass through
The work of vibrating controller control vibration electromagnet, vibration electromagnet generate intermittent magnetic force and screen are attracted to generate certain frequency
The position that speckle in screen is formed is upset in vibration by the vibration of screen, so that speckle is at fluidized state, when reaching certain frequency
When the vibration of rate, human eye is with regard to imperceptible speckle."
The shortcomings that mode of this magnet vibratory drilling method is: manufacturing cost is higher, and market receptance is not high.
2. acoustic vibration method: a certain number of loudspeaker are installed at screen rear, loudspeaker generate sound wave and are transmitted in screen,
Vibrate screen.
The defect of this mode is: the intensity of vibration can weaken rapidly as screen increases at a distance from sound source, so
It is very tight to loudspeaker and the required distance of screen, but with the variation in season, the degree that screen is tightened is different, thus loudspeaker with
The distance of screen is difficult to hold, and the environmental condition and construction quality requirement to movie theatre are extremely stringent, and cost is whole higher, also,
Whister-type noise can be led to the problem of.
3. vibrating mass vibratory drilling method: being bonded micro-vibration component at the screen back side, driven by the vibration of micro-vibration component
Screen vibration, is vibrated by screen and eliminates speckle.
Such as Patent No. " 201721206399.4 ", the patent that patent name is " laser speckle removing device of screen ",
Disclose " including a drive control box, several vibration modules and motor supply lines composition；Several vibration modules are distributed in
The screen back side, vibration module are made of a micromotor, a vibration template bottom plate and an eccentric block, vibration template bottom
By the fixed micromotor of glue on plate, the output shaft of micromotor is by glue fixed eccentric block, when work, passes through motor and turns
It is dynamic, eccentric block rotation is driven, unbalanced centripetal force is generated, unbalanced centripetal force causes vibration module to do radial motion, from
And cause the vibration of screen, the position that speckle is formed is upset, the fluidized state of speckle is formed, so that being weakened the phenomenon that speckle
To elimination, so that speckle phenomena when using laser-projector in screen be effectively relieved."
The shortcomings that this mode, is: will appear obvious protrusion in screen, and forms shade in screen front, influences screen
The image quality and viewing effect presented, and maintenance rate is higher, and maintenance cost is high.
Therefore needing a kind of vibration to eliminate, speckle effect is good, structure is simple, easy to maintain, the low-cost silver except speckle
Curtain frame.
