In the sound wave touch device, the existing structure does not need to be adjusted, and water can not permeate to a waterproof region, therefore, the interference on the sensing of a touch signal caused by dropping glue can be avoided, the machining precision of a front border can be reduced, and the interference on the sensing of the touch signal caused by a sealing body can be reduced or avoided.
Description
Technical field
The utility model relates to a kind of acoustic wave touch device, relates in particular to a kind of acoustic wave touch device of new waterproof structure.
Background technology
The acoustic wave touch device is in use often paid attention to water resistance especially as acoustic wave touching screen and sound wave touch display.And the sound wave waterproof touching device on the present society mainly adopts following several waterproof type: a kind of is the mode of dripping the glue sealing that adopts between frame and acoustic wave touching screen touch face, the defective of this kind mode is that width that drips glue and thickness are difficult to control, wide blocked up meeting has a strong impact on the transmission of touch-screen acoustic signals, influence touch screen performance, yet the thin waterproof effect that do not reach again of narrow mistake, in transportation or use, split easily between fluid sealant and the frame simultaneously, thereby cause the waterproof effect forfeiture.
Also having a kind of is the mode that adopts flexible sealing body (as rubber) sealing between former frame and the acoustic wave touching screen touch face, mainly contain, former frame touches the face edge near touch-screen a groove, the inside embeds the rubber strip of definite shape, then the form by mechanical pressure with rubber strip tightly be attached to touch screen surface, reach waterproof effect.For example China Patent No. " 200920027298.X " discloses a kind of touch LCD display with water-proof function, its applying date is on June 19th, 2009, Granted publication day is on February 24th, 2010, comprise fore shell, touch-screen and liquid crystal display, closely be pasted with waterproof adhesive tape between fore shell and the touch-screen.For another example, China Patent No. " 200920114149.7 " discloses a kind of touch display, comprise touch-screen and be arranged on touch-screen frame on every side, scuncheon is provided with three ribs, form two grooves between the adjacent rib, be equipped with sealing strip respectively in two grooves, sealing strip touches with touch-screen and cooperates.Adopt the defective of adhesive tape waterproof to be: adopt the defective of adhesive tape waterproof to be: one, requirement on machining accuracy is high, a slit can not occur; In case two mechanical pressures are inhomogeneous or deformation has taken place preceding frame, all make touch-screen touch display forfeiture waterproof action easily; Three, waterproof fully puts in because of adhesive tape is one whole, but has seam in bonding part, adhesive tape two.
Summary of the invention
The purpose of this utility model is to overcome existing acoustic wave touch device above shortcomings, a kind of acoustic wave touch device of new waterproof structure is provided, the utility model does not need to adjust to existing structure, can make water can't be penetrated into anti-aqua region, can avoid dripping the interference that glue forms the touch signal sensing, frame machining accuracy before can also reducing, the interference that reduces or avoid seal that the touch signal sensing is formed.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of acoustic wave touch device of new waterproof structure, comprise touch-screen and touch-screen frame all around, it is characterized in that: described frame is provided with the hydrophobic material layer or is provided with the hydrophobic material layer with the touch face of frame contact position, or is provided with the hydrophobic material layer on the touch face of frame and touch-screen.
Described hydrophobic material layer is coated on the frame or on the touch face of being coated in, or is coated on frame and the touch face.
Described frame is provided with the hydrophobic material layer, and the hydrophobic material layer is arranged on the frame near the touch viewing area of touch-screen.
Described and the touch face frame contact position is provided with the hydrophobic material layer, and the hydrophobic material layer is arranged on the touch viewing area of the touch-screen corresponding with frame.
Be provided with the hydrophobic material layer on the touch face of described frame and touch-screen, the hydrophobic material layer is arranged on the touch viewing area near the frame of the touch viewing area of touch-screen and the touch-screen corresponding with frame.
Described hydrophobic material layer is a silastic-layer.
Adopt advantage of the present utility model to be:
One, the utility model is owing to be provided with the hydrophobic material layer, when near frame and the close touch viewing area of touch-screen water being arranged, because the effect of hydrophobic material layer can make water be condensed into the very big globule of contact angle, water just can't be penetrated into anti-aqua region through the touch face contact position of frame and touch-screen like this.
Two, the utility model is simple to operate, and existing structure is not needed to adjust, and can save a large amount of manpower and materials and financial resources.
Three, the utility model can avoid dripping the interference that glue forms the touch signal sensing because the hydrophobic material layer is set; Frame machining accuracy before can also reducing, the interference that reduces or avoid seal that the touch signal sensing is formed.

Wherein, 1, touch-screen, 2, the touch-screen striped, 3, the touch-screen transducer, 4, near the frame that touches the viewing area, 5, whole frame, 6, touch the viewing area.
Embodiment
A kind of acoustic wave touch device of new waterproof structure, comprise touch-screen and touch-screen frame all around, described frame is provided with the hydrophobic material layer or is provided with the hydrophobic material layer with the touch face of frame contact position, or is provided with the hydrophobic material layer on the touch face of frame and touch-screen.
In the utility model, be coated in the hydrophobic material layer on the frame or on the touch face of being coated in, or be coated on frame and the touch face.
The hydrophobic material layer can be arranged on the frame near the touch viewing area of touch-screen.Also the hydrophobic material layer can be arranged on the touch viewing area of the touch-screen corresponding with frame.The hydrophobic material layer can also be arranged on the touch viewing area near the frame of the touch viewing area of touch-screen and the touch-screen corresponding with frame.
The hydrophobic material layer that adopts in the utility model is that silastic-layer or other have the dielectric layer of hydrophobic/hydrophobic effect.
