Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, clear, develop simultaneously implementation referring to the drawings
The utility model is further described in example.It should be appreciated that specific embodiment described herein is only used to explain this reality
With novel, it is not used to limit the utility model.
As shown in Figure 1 and Figure 2, a kind of to be based on OLED screen curtain sounding device, it include OLED screen curtain 100, OLED screen curtain
(Organic Light Emitting Display) i.e. organic light emitting display, OLED display technology and traditional LCD are shown
Mode is different, is not necessarily to backlight, the very thin coating of organic material of use and glass substrate, when a current passes through, these have
Machine material will shine.And OLED display screen can be made lighter and thinner, and visible angle is bigger, and can significantly save
Save power consumption.OLED screen curtain sounding device further includes the vibration of driving OLED screen curtain 100 positioned at 100 lower section of OLED screen curtain to make
The piezoelectric vibrator 200 of 100 sounding of OLED screen curtain, this sounding device are applied on a television set, since OLED screen curtain 100 can be done
To lighter and thinner, the vibration in OLED screen curtain sounding device through piezoelectric vibrator 200 can drive the vibration hair of OLED screen curtain 100
Sound, the direction of vibration of piezoelectric vibrator 200 realize the sounding before screen perpendicular to OLED screen curtain 100,100 turns of OLED screen curtain
It has been melted into loudspeaker, so that sound can preferably be combined with picture, it is synchronous with phonotape and videotape to reach more perfect phonotape and videotape combination.
As shown in Figure 2 and Figure 3, piezoelectric vibrator 200 includes the fixation supporting point being fixedly connected on OLED screen curtain 100
210, the upper surface of fixed supporting point 210 is by being adhesively fixed on the back side of OLED screen curtain 100, and is symmetrically fixedly connected on
Determine the lower surface of supporting point 210 and generates the first bending vibrator 220 and the second bending vibrator of vibration by input ac voltage
230.Fixed supporting point 210 is that structural type is Nian Jie with the bonding way of OLED screen curtain 100, and structural type bonding is to use structural unit
The bonding phenomenon that adhesive is rigidly secured together.Sqtructural adhesive used in it and its adhesive spots must be able to transferring structure
Stress does not influence the integrality of its structure and the applicability to environment in scope of design；Stress transfer in bonded assembly with
Traditional mechanical fasteners are compared, stress distribution more evenly, and be bonded modular construction it is higher than mechanical fasteners intensity, it is at low cost,
Light weight.If thin-wall part sticky object is adhered on thick-walled product, whole intensity of thin-wall part can be given full play to.
As shown in figure 3, the first bending vibrator 220 is identical as 230 structure of the second bending vibrator, and the first bending vibrator 220
Synchronous vibration is generated by the input of alternating current respectively with the second bending vibrator 230, the vibration that the two generates forms superposition, leads to
It crosses fixed supporting point 210 to be transmitted on OLED screen curtain 100 that vibration is made to become larger, since existing television screen size is to more
Develop come bigger direction, needs big vibration to drive big OLED screen curtain 100, then by acoustics design, volume can be obtained
Maximum, the optimal effect of sound quality.
As shown in figure 3, it includes substrate 221 that the first bending vibrator 220 or 230 specific structure of the second bending vibrator, which are, with
And it is pasted and fixed on the piezoelectric patches 222 of the upper surface of substrate 221, the middle part of substrate 221 is extended with casting lug thereon 224, institute to side
It states casting lug thereon 224 to be fixedly connected with fixed supporting point 210, the casting lug thereon of the first bending vibrator 220 and the second bending vibrator 230
224 are respectively symmetrically adhesively fixed on the lower surface of fixed supporting point 210.Substrate 221 is metal substrate, and piezoelectric patches 222 is ceramics
Piezoelectric patches, piezoelectric ceramics piece may be configured as multilayer, to enhance vibrating effect, the piezoelectric ceramics piece in the present embodiment is set as one
Layer；Its course of work is introduced by taking the first bending vibrator 220 as an example, when piezoelectric patches 222 stretches, the first bending vibrator 220
It will be bent upwards, when piezoelectric patches 222 is shunk, the first bending vibrator 220 will be bent downwardly, so, when to first
The voltage that bending vibrator 220 alternately changes plus one, then it will be bent up and down with the variation of voltage and ceaselessly, from
And push air sounding.Therefore, the first bending vibrator 220 passes through the fixed abutting of supporting point 210 OLED screen curtain 100, the first bending
The bending up and down synchronous with the second bending vibrator 230 of oscillator 220 drives the vibration of OLED screen curtain 100 to realize screen sounding.
The length of piezoelectric patches 222 is shorter than substrate 221, and piezoelectric patches 222 is located at the middle position setting of substrate 221, in substrate
The both ends not covered by piezoelectric patches 222 on 221 are free end 223, and described two free ends 223 are symmetrically fixedly connected with clump weight
225, clump weight 225 may be provided at the upper surface or lower surface of free end 223, and clump weight 225 is bonded in freedom in the present embodiment
The upper surface at end 223.It is symmetrically installed clump weight 225 two free ends 223, the first fixed bending vibrator 220 intermediate in this way
Or when the second generation vibration of bending vibrator 230, the acceleration of generation is symmetrically that resultant force is vertical screen, can be passed to
The vibration acceleration in the bigger vertical screen direction of screen, then by acoustics design, volume maximum, the optimal effect of sound quality can be obtained
Fruit.
As shown in Figure 1, there are two piezoelectric vibrators 200 for setting on OLED screen curtain 100, pass through two piezoelectric vibrators
200 synchronous driving OLED screen curtains 100, make 100 sounding of OLED screen curtain reach balance.The longest edge direction of OLED screen curtain 100 is length
Direction is spent, the second longitudinal direction of OLED screen curtain 100 is width direction, and two piezoelectric vibrators 200 are symmetrically arranged at
1/4 and 3/4 position of the length direction of OLED screen curtain 100, described two piezoelectric vibrators 200 are located at OLED screen curtain 100
Localization of sound and spatial impression are realized in the middle position of width direction.Entire OLED is driven by the vibration of piezoelectric vibrator 200
100 synchronous vibrating sounding of screen equally realizes sounding forward although loudspeaker are later, and the direction for solving high pitch is asked
Topic.
The utility model proposes one kind to be based on OLED screen curtain sounding device, due to passing through piezoelectric vibrator in technical solution
Vibration drives entire OLED screen curtain synchronous vibrating sounding to substitute traditional high-pitched speaker, so that television set be avoided to increase high-pitched speaker
The speaker net of institute's band directly affects the overall appearance of television set below screen, and solving traditional high-pitched speaker range of voice has
Limit, user can not be in a wide range of interior the problem of hearing the sound of high quality.Had based on OLED screen curtain sounding device and passes through screen
Direct sounding, and structure is simple, the characteristics of improving user experience.
It should be understood that the application of the utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come
