Fig. 1 describes the structural representation of touch detecting apparatus 100 according to an embodiment of the invention.Below with reference to Fig. 1, this touch detecting apparatus 100 is described.
See Fig. 1, according to an example of the present invention, touch detecting apparatus 100 is layer structure, comprises, and vibration generating layer 110, for receiving the first voltage signal, and produces the first vibration according to the first voltage signal; Vibration receiving layer 120, for receiving the touch of the first vibration and/or operating body directly or indirectly, and according to first vibration and/or operating body touch and produce touch operation signal.Alternatively, touch detecting apparatus 100 can also involving vibrations transport layer 130, between vibration generating layer 110 and vibration receiving layer 120, for the first vibration passing of vibration generating layer 110 being produced to vibration receiving layer 120.
Describe to the 26S Proteasome Structure and Function of the vibration generating layer 110 in touch detecting apparatus 100 and vibration receiving layer 120 respectively below.
According to an example of the present invention, participate in Fig. 1, the vibration generating layer 110 in touch detecting apparatus 100 comprises first medium layer 111, first electrode 112.First medium layer 111 has two relatively large surfaces, and the first electrode 112 is positioned at the both sides on two relatively large surfaces of first medium layer 111.Vibration receiving layer 120 in touch detecting apparatus 100 comprises: second dielectric layer 121, the second electrode 122.Second dielectric layer 121 has two relatively large surfaces too, and the second electrode 122 lays respectively at the both sides on second dielectric layer 121 two relatively large surfaces.Alternatively, the first electrode 112 and the second electrode 122 can be made up of upper/lower electrode layer respectively.Such as, the first electrode 112 comprises the first upper electrode layer 1121 and the first lower electrode layer 1122; Second electrode 122 comprises the second upper electrode layer 1221 and the second lower electrode layer 1222.First upper electrode layer 1121 and the first lower electrode layer 1122 lay respectively at the both sides of first medium layer 111; Second upper electrode layer 1221 and the second lower electrode layer 1222 lay respectively at the both sides of second dielectric layer 121.
According to another example of invention, in the embodiment of involving vibrations transport layer 130, vibration transmission layer 130 is between first electrode 112 and the second electrode 122 of vibration receiving layer 120 of vibration generating layer 110.Such as, vibration transmission layer 130 can between the first upper electrode layer 1121 of the first electrode 112 of vibration generating layer 110 and the second lower electrode layer of the second electrode 122 vibrating receiving layer 120.
According to said structure, touch detecting apparatus 100 is not when receiving touch and when receiving touch operation, and its vibrational state is different.Such as, when the operation such as touch-control, gripping is carried out in the position being configured with touch detecting apparatus 100 in user is not to electronic equipment, vibration generating layer 110 and the vibration receiving layer 120 of touch detecting apparatus 100 are in initial vibration state.And when user is when using electronic equipment, when touching the position being configured with touch detecting apparatus, vibration generating layer 110 and whole the receiving layer 120 of touch detecting apparatus 100 are in touch vibrational state.At touch vibrational state, touch detecting apparatus 100 will detect user's touch operation.
When touch detecting apparatus 100 does not receive touch operation, the first electrode 112 in vibration generating layer 110 receives the first voltage signal to make to produce electric potential difference between the first upper electrode layer 1121 and the first lower electrode layer 1122.Now, there is deformation due to the driving of electric field force and produce the first vibration in the first medium layer 111 (can be made up of piezoelectric) between the first upper electrode layer 1121 and the first lower electrode layer 1122.Afterwards, this first vibration is continued the second dielectric layer 121 (can be made up of piezoelectric) being transferred to vibration receiving layer 120 by first medium layer 111, second dielectric layer 121 produces the second vibration after receiving the first vibration, cause second electrode 122 on second dielectric layer 121 both sides to produce electric field thus produce the first electric signal, this electric signal namely can as the original touch detection signal of electronic equipment when not receiving any touch.
The opposing party aspect, touch detecting apparatus 100 is when the touch operation receiving user, and working method is as follows.The first electrode 112 in vibration generating layer 110 receives the first voltage signal to make to produce electric potential difference between the first upper electrode layer 1121 and the first lower electrode layer 1122.Now, there is deformation due to the driving of electric field force and produce the first vibration in the first medium layer 111 (can be made up of piezoelectric) between the first upper electrode layer 1121 and the first lower electrode layer 1122.Afterwards, this first vibration is continued the second dielectric layer 121 (can be made up of piezoelectric) being transferred to vibration receiving layer 120 by first medium layer 111, second dielectric layer 121 produces the second vibration after receiving the first vibration, and this vibration will cause second dielectric layer 121 liang of lateral electrodes to produce voltage.Such as, the generation of the second vibration, can cause second dielectric layer 121 that deformation occurs, and deformation causes two end electrodes to produce electric potential difference, coating-forming voltage.Meanwhile, when there being touch operation, touch operation through the metal shell of electronic equipment, and can pass to the vibration receiving layer 120 of the touch detecting apparatus 100 of its inside.Therefore, the vibration receiving layer 120 of touch detecting apparatus 100 is when the touch operation receiving user, touch operation causes the second dielectric layer 121 vibrating receiving layer 120 to occur to touch deformation, the combination of the second vibration and touch deformation, cause second electrode 122 on second dielectric layer 121 both sides to produce electric field thus produce the second electric signal, this second electric signal is the touch operation signal that detect of electronic equipment when receiving touch operation.
Like this, when the touch detecting apparatus 100 of electronic equipment detects, touch detection signal different from the original touch detection signal under no touch state, then can according to ratio relation therebetween, difference relationship, the parameters such as matching degree determine the information such as time, dynamics, position that user touches.
According to an example of the present invention, the first electrode 112 in above-mentioned vibration generating layer 110 receives the first voltage signal and can be produced by the voltage input unit 115 of touch detecting apparatus 100.The first voltage signal that voltage input unit 115 sends can be periodically, also can be aperiodicity.Such as, can be square wave, sine wave.Certainly, those skilled in the art are to be understood that, the device that voltage input unit 115 also can be touch detecting apparatus 100 outside, be connected with touch detecting apparatus 100, such as, voltage input unit 115 can be the miscellaneous part in electronic equipment, under the instruction of electronic equipment, regularly or aperiodically send the first voltage signal to touch detecting apparatus 100.
According to an example of the present invention, first medium layer 111 and/or second dielectric layer 121 can be made up of piezoelectric, piezoelectric can produce piezoelectric effect, when piezoelectric dielectric is subject to the effect of external force and is out of shape in a certain direction, its inside can produce polarization phenomena, occurs positive and negative contrary electric charge in its two opposing outer face simultaneously.After external force is removed, it can return to uncharged state again, and when the direction of acting force changes, the polarity of electric charge also changes thereupon.On the contrary, when applying electric field on polarization of dielectric direction, these dielectrics also can deform, and after electric field removes, dielectric distortion disappears thereupon.According to an example of the present invention, first medium layer 111 and/or second dielectric layer 121 produce ultrasound wave or infrasonic wave when vibrating.This ultrasound wave or infrasonic wave can be plane waves also can be nonplanar wave.Alternatively, the first electrode 112 and the second electrode 122 are flexible electrodes, when first medium layer 111 and/or second dielectric layer vibration, also deformation can occur, and while transmitting vibrations, ensure less vibration loss rate.
The embodiment of the present invention constructs touch detecting apparatus by using electrode layer and dielectric layer, the detection of the touch operation to user is achieved by the corresponding conversion of electric signal and force value, due in testing process, vibration wave can't be shielded by the metal shell of electronic equipment, and therefore the touch operation of the embodiment of the present invention to the various electronic equipments comprising metal shell can effectively detect.
