Any one of or more persons all combinations.
A is please referred to Fig.1, Figure 1A is the schematic diagram of the intelligent apparatus of the embodiment of the present invention.Intelligent apparatus 1 is pressed including condenser type
Key module 10 and control module 11.Capacitance key module 10 is set to 1 surface of intelligent apparatus, capacitance key module 10 compared with
It is good to be arranged on the side of intelligent apparatus 1, operate intelligent apparatus 1 to provide user.Capacitance key module 10 for example may be used
Think the solution lock-switch or volume control switch of intelligent apparatus 1, but is not limited thereto.User can penetrate and operate the capacitance
Formula key-press module 10 is to generate pressing signal and displacement signal.In addition, capacitance key module 10 includes first electrode layer
101, elastic layer 102, the second electrode lay 103 and contact layer 104.It will be under as the thin portion structure of capacitance key module 10
Square paragraph describes in detail.

Referring to Fig. 2, Fig. 2 is the Organization Chart of the capacitance key module of the embodiment of the present invention.Capacitance key module 10
Including first electrode layer 101, elastic layer 102, the second electrode lay 103 and contact layer 104.Contact layer 104 is not preferably to lead
Electric material is constituted, and displacement operation and pressing operation are carried out thereon to provide user.
First electrode layer 101 has an at least first electrode (Fig. 2 is not painted).The second electrode lay 103 is set to contact layer
Under 104, and the second electrode lay 103 includes that (Fig. 2 is not for an at least second electrode (Fig. 2 is not painted) and an at least third electrode
It is painted).First electrode forms the first inductance capacitance with second electrode, and first electrode or second electrode are to according to the first induction
The capacitance variation of capacitance generates pressing signal.Second electrode and third electrode form the second inductance capacitance, and second electrode or
Third electrode is to according to the capacitance variation of the second inductance capacitance generation displacement signal.
Elastic layer 102 is set between first electrode layer 101 and the second electrode lay 103.Elastic layer 102 is by nonconducting bullet

Key module 10 becomes according to the capacitance of its second inductance capacitance (being formed by the second electrode and third electrode of the second electrode lay 103)
Change and generates displacement signal.The control unit (Figure 1B is not painted) of control module 11 receives pressing signal or receives pressing signal
And intelligent apparatus 1 is controlled again after displacement signal and executes corresponding action.
For example, when capacitance key module 10 is as solution lock-switch, user can penetrate pressing condenser type and press
Key module 10 is to generate pressing signal.After control module 11 receives pressing signal, control unit is solved intelligent apparatus 1 is controlled
Lock its screen.Alternatively, user can penetrate press and slide pressing capacitance key module 10 with generate pressing signal and
Displacement signal.After control module 11 receives pressing signal and displacement signal, control unit is unlocked intelligent apparatus 1 is controlled
Its screen.
Again for example, when capacitance key module 10 is volume control switch, user also passes through pressing and cunning
Dynamic pressing capacitance key module 10 is to generate pressing signal and displacement signal.Control module 11 receive pressing signal and
After displacement signal, control unit will control intelligent apparatus 1 and adjust its volume.It is noted that above-mentioned lifted condenser type is pressed
10 corresponding function of key module is only for example, and the present invention does not limit 10 corresponding function of capacitance key module.In following reality
It applies in example, capacitance key module 10 has the function of solving lock-switch and volume control switch simultaneously.
