[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 101 and for driving the bimorph 103 of display screen component 102 vibration sounding.Wherein, the first fixed part 106 that bracing frame 101 comprises main part 105, main body 105 two ends extend respectively and the second fixed part 107 and be located at main part 105 both sides and clamping plate 104, first fixed part 106 be connected with main part 105 and the second fixed part 107 between two clamping plates 104.Display screen component 102 comprises screen 102A that two ends are connected with the second fixed part 107 with the first fixed part 106 respectively and is located at display screen 102B below screen 102A and separated by a distance with screen 102A, and display screen 102B is clamped wherein by two clamping plates 104 and separated by a distance with screen 102A.In the present embodiment, screen 102A is interior curved Curved screen, and display screen 102B can be introversion type Curved screen, also can be plane screen.
As shown in Figure 3, in the present embodiment, first fixed part 106 is identical with the structure of the second fixed part 107, for the first fixed part 106, first fixed part 106 is formed with the first clamping part 106A near display screen 102B, the second clamping part 106B relative with the first clamping part 106A, the containing cavity 106C surrounded by the first clamping part 106A and the second clamping part 106B and from the first fixed part 106A and the second clamping part 106B along the supporting part 108 that the length direction of bimorph 103 extends respectively, supporting part 108 is away from the first clamping part 106A and the second clamping part 106B.One end of screen 102A is positioned at containing cavity 106C, and abuts with the first clamping part 106A and the second clamping part 106B.Bimorph 103 is positioned at below display screen 102B and its two ends and is connected with the supporting part 108 of the first fixed part 106 with the second fixed part 107 respectively.The two ends of screen 102A can be bonding with the first fixed part 106 and the second fixed part 107 by glue, same, the two ends of bimorph 103 also can be connected with the supporting part 108 of the first fixed part 106 with the second fixed part 107 by glue respectively, can structure be simplified to fix by glue is bonding, reduce the technology difficulty of screen and actuator.But, also other fixed structure can be adopted to improve the reliability of vibrational system, such as, the connection of screen and bracing frame can adopt multiaspect bonding and add the mode of draw-in groove, and the connection of actuator and supporting part can also adopt piezoelectricity to sinter the mode of substrate then fastened by screw.
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, and the amplitude of bimorph is changed a lot, thus produces vibration.The two ends of screen 102A are connected with the second fixed part 107 with the first fixed part 106 respectively, and the two ends of bimorph 103 are connected with the supporting part 108 of the first fixed part 106 with the second fixed part 107 respectively, form the vibrational system that is similar to bow and arrow, the stretching vibration of bimorph 103 passes to screen 102A by the first fixed part 106 and the second fixed part 107, cause screen 102A to do flexural vibrations, flexural vibrations drive load air to realize acoustic irradiation.Screen 102A 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 larger, unbending material is good, and the transmission efficiency being conducive to improving vibration so also can effectively avoid vibration passing to other irrelevant structures simultaneously.In other embodiments, the two ends of screen also can directly be connected with the two ends of actuator, and so the stretching vibration of actuator need not be directly passed to screen by bracing frame, thus drive screen vibration sounding, but this structure needs to consider technology difficulty.
The structure of this bow-arrow type that screen 102A and bimorph 103 are formed, makes this screen sound-producing device 100 need add less piezoelectric patches space and can realize vibration sounding, greatly can improve the space availability ratio of wearable device.Moreover, display screen 102B and screen 102A is separated by a distance, and display screen 102B does not contact with actuator 103, avoid display screen 102B and Direct driver screen 102A sounding, vibrational system can be avoided the impact of viewing area on the one hand, the trim designs of screen 102A and display screen 102B 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.
