The present invention also proposes a kind of terminal device, which includes analogue-key, the specific structure of the analogue-key
At least have referring to above-described embodiment since this terminal device uses whole technical solutions of above-mentioned all embodiments
All beneficial effects brought by the technical solution of above-described embodiment, this is no longer going to repeat them.
The present invention also proposes a kind of control method of analogue-key.
Referring to Fig. 4, in an embodiment of the present invention, comprising the following steps:
Step S10, the reflected light for the detection light propagated along the axis direction of analogue-key is obtained；
Step S20, the pressing stroke of analogue-key is determined according to reflected light；
Step S30, corresponding operation signal is issued according to pressing stroke.
In the present embodiment, the light propagated along the axis direction of analogue-key is either the component of analogue-key itself is sent out
Out, it is also possible to provided by other equipment, also, its direction of propagation is also possible to either towards the direction of keycap
Backwards to the direction of keycap, as long as the distance between reception position of turn back position and reflected light of detection light can be as keycap presses
The increase of stroke and reduce；In this way, being pressed with keycap, reflected light can have variation, when the signal of analogue-key
After processing unit receives the variation of the reflected light, the pressing stroke of analogue-key can be determined according to presupposed information, further according to
Identified pressing stroke issues corresponding operation signal；In other words, the technical program realize by photosignal determine by
Stroke is pressed, and realizes the operation signal output of analogue-key.

The pressing stroke of key；The mode of acquisition analogue-key pressing stroke herein may include calculating, it will be understood that described at this time
Presupposed information is corresponding calculating function, and normally, light intensity variation is positively correlated with pressing stroke, general proportional, can also
Be it is nonlinear, certainly, the mode of acquisition analogue-key pressing stroke herein can also be including analogue simulation etc..So originally set
Count without being limited thereto, the step S30 may further be embodied as: according to the variation of the light intensity of reflected light and preset light intensity variation-pressing row
Journey corresponding relationship obtains the pressing stroke of analogue-key；It is appreciated that the presupposed information is light intensity variation-pressing row at this time
Journey corresponding relationship, signal processing unit can obtain pressing stroke simply by the mode of inquiry, and certainly, which changes-press
Pressure stroke corresponding relationship needs to obtain by preparatory experiment.
In the present embodiment, further, the keycap of analogue-key has transmittance section, sends the detection towards transmittance section
Light determines that keycap is touched when the reflected light light intensity got is greater than or equal to preset value.In this way, when user's finger is not put
When on keycap, the detection light can be transmitted away directly by transmittance section, without will form reflected light；And work as user's finger
It when being placed on keycap, after the detection light passes through transmittance section, can be turned back through finger, and form reflected light, can will then be reflected
Light light intensity feeds back the signal processing unit to analogue-key, thus when reflected light light intensity is greater than or equal to preset value, determination key
Cap, which has, to be touched.I other words the analogue-key of the present embodiment technical solution, no setting is required the additional structure and circuit the case where
Under, so that it may recognize the finger for being only placed on keycap but not pressed.
In the present embodiment, further, determining that keycap by before touching, sends the detection towards transmittance section to discontinuous
Light, in this way, the energy consumption of the analogue-key can be saved.
Further, after determining that keycap is touched, the detection light constantly is sent towards transmittance section, until determination key
Cap is no longer touched；In this way, can more effectively judge whether the analogue-key is in the state touched for a long time.It does not lose
Generality, the analogue-key are generally applicable to game paddle, and the short time is touched operation corresponding to pressing (clicking)
Instruction, and to be touched operational order corresponding to pressing (long-pressing) for a long time usually different, for example, in the game paddle
When applied to shooting game, analogue-key clicked corresponding operational order be usually shoot it is primary, and be long pressed pair
The operational order answered is usually continuous fire.
It should be noted that in the present embodiment, after determining that keycap is no longer touched, it is possible to determine that, simulation is pressed at this time
Key is to determine keycap by before touching, and used detection light sending method is discontinuous.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly

Corresponding operation signal is issued according to the pressing stroke.
9. the control method of analogue-key as claimed in claim 8, which is characterized in that described to determine institute according to the reflected light
The step of stating the pressing stroke of analogue-key specifically:
Changed according to the light intensity of the reflected light, obtains the pressing stroke of the analogue-key；Alternatively,
According to the variation of the light intensity of the reflected light and preset light intensity variation-pressing stroke corresponding relationship, obtains the simulation and press
The pressing stroke of key.
10. the control method of analogue-key as claimed in claim 8 or 9, which is characterized in that the keycap of the analogue-key has
There is transmittance section, send the detection light towards the transmittance section, when the reflected light light intensity got is greater than or equal to preset value, really
The fixed keycap is touched.
11. the control method of analogue-key as claimed in claim 10, which is characterized in that determining that the keycap touched it
Before, the detection light is sent to discontinuous towards the transmittance section, and
After determining that the keycap is touched, the detection light constantly is sent towards the transmittance section, until determining the key
Cap is no longer touched.
