Abstract
The utility model provides a multi-zone sound wave touch screen. The utility model comprises a touch screen body, transmitting and receiving strips, a transmitting transducer and a receiving transducer, which are corresponding to the transmitting and receiving strips. The transmitting transducer and the receiving transducer are both mounted on the corner and the edge of the screen body; at least two groups of strips in the transmitting and receiving strips are mounted in the non-peripheral area of the screen body; the other strips are mounted in the surrounding area of the screen body; at least two or more than two enclosed spaces which are composed by the transmitting strips, the receiving strips, the transmitting transducer and the receiving transducer are mounted on the touch screen body. The utility model can realize the function that the same touch screen is provided with two or more than two independent touch areas and each area can identify the touch independently. Therefore the simultaneous multi-point touch for the whole touch screen is realized; the multi-zone sound wave touch screen also effectively increases the size of a single touch screen.
Description
Technical field
The utility model relates to a kind of touching device, relates generally to a kind of multi partition acoustic wave touching screen.
Background technology
In the prior art, touch-screen mainly is divided into electric resistance touch screen, acoustic wave touching screen, infrared touch panel, capacitance touch screen etc., and among this, acoustic wave touching screen has advantages such as stable performance, good, the anti-riot property of light transmission be good, but owing to itself principle features determines, as realizing the multiple point touching difficulty, transducing signal decay that is directly proportional simultaneously along with transmitting distance, and then cause the screen body of touch screen size to be restricted, do big difficulty.
Mostly adopt conventional single district mode in the existing technology of acoustic wave: promptly whole touch screen is by 2 transmitting transducers (or emission substrate, the guiding striped), 2 receiving transducers (or receive substrate, the guiding striped), 2 groups of emission stripeds, 2 group of received stripeds are formed four limits and are surrounded the zone, wherein 1 angle is equipped with 2 orthogonal sound wave emissions or receiving transducer, and all the other 2 transducers are separately positioned on adjacent 2 angles that the angle of 2 orthogonal sound wave emissions or receiving transducer is installed on the screen body; Four peripheries of screen body then are carved with 45 degree or 135 and spend by dredging 4 groups of very accurate reflection strips of close spacing.The ultrasound wave that has the surface acoustic wave touch screen of forming by single district mode now need propagate into all touch areas of whole screen body, because same touch-screen is a propagation regions only, the touch area of touch-screen is done greatly and is restricted, needing to be not suitable for the industry and the place of giant-screen, be unfavorable for the centralized management and the running of information, reduce work efficiency, increased user's cost; Realization multiple point touching difficulty.
In the existing technology of acoustic wave employing cascade mode is arranged also, the reception parallel operation that is equipped with more than five or five in the screen surface (or receives substrate, striped leads) and transmitting transducer (or emission substrate, the guiding striped), be carved with on the display screen surrounding that makes of glass that corresponding 45 degree or 135 degree are by dredging the close very reflection strip of precision more than five groups or five groups, the thin end of reflection strip becomes an angle of 90 degrees with transducer or substrate.Adopt the effective touch area of the utility model cascade to increase, the area of surface acoustic wave touch screen can satisfy screen body size and make big needs, but realize the multiple point touching difficulty to a certain extent greater than single district touch-screen area.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technological deficiency, and a kind of multi partition acoustic wave touching screen is provided.The utility model can be implemented in has independent touch area more than 2 or 2 on the same touch-screen, touch can be independently discerned in each zone, thereby multiple point touching when reaching whole touch screen can also effectively increase the size of single touch-screen.
For achieving the above object, the technical solution adopted in the utility model is:
The multi partition acoustic wave touching screen comprises screen body of touch screen, emission, receives striped, and with emission, receive the corresponding emission of striped, receiving transducer, it is characterized in that: emission, receiving transducer all are arranged on the angle, limit of screen body; At least 2 group stripeds are arranged on the non-neighboring area of screen body in emission, the reception striped, and all the other are arranged on screen body periphery; Have at least on the described screen body of touch screen more than 2 or 2 by the emission striped, receive surrounding that striped, transmitting transducer, receiving transducer form.
The described zone that surrounds comprises at least 2 transmitting transducers, at least 2 zones that receiving transducer, at least 2 groups emission striped, at least 2 group of received stripeds are formed.
Described 1 group of emission striped is meant: with transmitting transducer the combination of many parallel emission stripeds of signal contact takes place directly.
Described 1 group of received striped is meant: with receiving transducer the combination of many parallel reception stripeds of signal contact takes place directly.
The striped that transmits and receives of described screen body is transparent or semitransparent or opaque.
Advantage of the present utility model is:
The utility model can be implemented in the multiple point touching more than 2 or 2 on the same touch-screen.So that the acoustic wave touching screen expanded application is in two people on the same touch-screen or occasion such as operation simultaneously more than two people,, acoustic wave touching screen expanded application single two or more fingers or other on same touch-screen occasion such as operate simultaneously so that touching body.
The utility model can also effectively increase single touch-screen size.So that under existing technology condition, produce the more large scale touch-screen demand of meeting the need of market.
