[embodiment]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of screen sound-producing device 100 comprises bracing frame 101, is located at the display screen component 102 on bracing frame 101 and is located on bracing frame and for driving the actuator 103 of display screen component 102 vibration sounding.Bracing frame 101 comprises the first fixed part 101B that main part 101A and main body 101A two ends extend respectively with the second fixed part 101C and be positioned at main part 101A both sides and the clamping plate 101C be connected with main part 101A, and the first fixed part 101B and the second fixed part 101C is between two clamping plates 101C.Display screen component 102 comprises screen 104 and is located at display screen 105 below screen 104 and separated by a distance with screen 104.Screen 104 has the first end 104A be connected with the first fixed part 101B and the second end 104B be connected with the second fixed part 101C.Display screen 105 is separately positioned on main part 101A both sides by two pieces and the clamping plate 101C be connected with main part 101A clamps wherein, and display screen 105 does not contact with actuator 103.In the present embodiment, screen 104 is interior curved Curved screen, and display screen 105 can be introversion type Curved screen, also can be plane screen.
As shown in Figure 3 and Figure 4, the first fixed part 101B containing cavity 109 of there is the first clamping part 106 of close display screen 104, second clamping part 107 relative with the first clamping part 106 and being surrounded by the first clamping part 106 and the second clamping part 107.As shown in Figure 2, screen 104 has the first surface 104C of close the display screen 105 and second surface 104D relative with first surface 104C, the first end 104A of screen 104 is positioned at containing cavity 109, and first surface 104C abuts with the surface of the first clamping part 106 towards containing cavity 109, second surface 104D abuts with the surface of the second clamping part 107 towards containing cavity 109.In the present embodiment, the structure of the second end 104B is identical with first end 104A, but the structure of the second end 104B can be not identical with first end 104A yet.
First clamping part 106 also has the through hole 106A and two through with containing cavity 109 near through hole 106A and along the support portion 108 extended away from the second clamping part 107 direction as shown in Figure 4.As shown in Figure 2, actuator 103 is positioned at through hole 106A and has at least part to be positioned at containing cavity 109, and it has the joint face 103A that is connected with screen 104 end and abuts with support portion 108 and the bearing surface 103B relative with joint face 103A.
In the present embodiment, first fixed part 101B and the second fixed part 101C is respectively provided with an actuator 103, optionally, also can selects a fixed part to arrange actuator wherein, one end of screen is connected with fixed part by this actuator, and the other end is directly connected with fixed part.Two actuators are stronger than the actuating force of an actuator, specifically can select according to Oscillation Amplitude and final sound pressure level demand.Actuator 103 can be bonding with the first fixed part 101B by glue, same, the first end 104A of screen 104 also can adopt glue bonding with actuator 103, this mainly considers from the angle reducing technology difficulty, if need more reliable connected mode, can consider that the mechanical structures such as draw-in groove are added at the position combined at both, make mechanical force and bonding force drive screen simultaneously, improve the stability of system.
Actuator 103 is preferably bimorph, bimorph is made up of the piezoelectric ceramic piece being positioned at middle glass fibre layered or carbon fiber interlayer and being covered in these interlayer both sides, due to the inverse piezoelectric effect of piezoelectric ceramic piece, when bimorph applying the voltage of forward, two panels piezoelectric ceramic has contrary polarised direction, wherein a slice piezoelectric ceramic piece is caused to do extensional vibration, then another sheet then does contraction flexural vibrations, the amplitude of bimorph is changed a lot, thus produces vibration.Because the first end 104A of screen 104 is connected with this actuator, the vibration of actuator 103 can pass to screen 104 by the first end 104A of screen 104, thus drives screen 104 vibration sounding.It should be noted that the direction of vibration of actuator 103 should be parallel with the tangential direction of screen 104 first end, the feature of Curved screen can be made full use of, realize efficient screen sounding vibrational system.And screen 104 should adopt the material that thinner thickness, Young's modulus are less to be good, be conducive to like this realizing larger distortion, and bracing frame 101 should adopt rigidity comparatively large, unbending material is good, is conducive to like this avoiding vibration passing to other irrelevant structures.
Actuator 103 is arranged on the first fixed part 101B and is connected with the first end of screen 104 and can make full use of the curved-surface structure of Curved screen, only need add less piezoelectric patches space can realize vibration sounding, greatly can improve the space availability ratio of wearable device.Moreover, display screen 105 is separated by a distance with screen 104, and display screen 105 does not contact with actuator 103, avoid display screen 105 and Direct driver screen 104 sounding, vibrational system can be avoided the impact of viewing area on the one hand, the trim designs of screen 104 and display screen 105 can be made freer on the other hand.Screen sound-producing device of the present utility model has that Structure and energy is simple, phonation efficiency high.
Above-described is only execution mode of the present utility model; it should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite not departing from the utility model creation design; improvement can also be made, but these all belong to protection range of the present utility model.
