In some embodiments, touch control operation includes：User once presses piezoelectricity module 30；And/or user is with first Preset interval time repeatedly presses piezoelectricity module 30.

In other words, during user's touch control operation piezoelectricity module 30, can be once press a piezoelectricity module 30 and make by Surging or compressing time meet trigger condition to trigger corresponding function services；Alternatively, user's touch control operation piezoelectricity module 30 When, it can be one piezoelectricity module 30 of multiple pressing and make the pressing dynamics of pressing piezoelectricity module 30 every time or compressing time satisfaction Trigger condition to trigger corresponding function services, wherein, it is adjacent twice press between time interval between the first preset time Every, the value of the first prefixed time interval should not be too large, for example, the value of the first prefixed time interval can be that 0.5s, 1s are equivalent, In this way, influence the usage experience of user to avoid the overlong time triggered needed for a certain function services.

Specifically, the correspondence between touch control operation and function services is illustrated by taking mobile phone as an example.For example, when mobile phone is in During off-mode, user once presses a piezoelectricity module 30 relevant with machine open/close and pressing dynamics is greater than or equal in advance If it can trigger mobile phone power-on during pressure value；When mobile phone is in open state, user once presses and machine open/close relevant one A piezoelectricity module 30 simultaneously makes pressing dynamics can trigger mobile phone shutdown when being greater than or equal to preset pressure value.Or for example, work as mobile phone During in off-mode, user once presses a piezoelectricity module 30 relevant with machine open/close and compressing time is more than or is waited It can trigger mobile phone power-on when preset time；When mobile phone is in open state, user once presses relevant with machine open/close One piezoelectricity module 30 simultaneously makes compressing time can trigger mobile phone shutdown when being greater than or equal to preset time.Or for example, work as mobile phone During in off-mode, the pressing of user's continuous several times is with the relevant piezoelectricity module 30 of machine open/close and making to press piezoelectricity every time The pressing dynamics of module 30 can trigger mobile phone power-on when being greater than or equal to preset pressure value；When mobile phone is in open state, User's continuous several times press with the relevant piezoelectricity module 30 of machine open/close and make the pressing dynamics of pressing piezoelectricity module 30 every time It can trigger mobile phone shutdown during more than or equal to preset pressure value.Or for example, when mobile phone is in off-mode, user is continuously more The secondary compressing time for pressing a piezoelectricity module 30 relevant with machine open/close and making pressing piezoelectricity module 30 every time is greater than or equal to It can trigger mobile phone power-on during preset time；When mobile phone is in open state, the pressing of user's continuous several times is related to machine open/close A piezoelectricity module 30 and make pressing piezoelectricity module 30 every time compressing time be greater than or equal to it is i.e. triggerable during preset time Mobile phone shutdown.

Similarly, volume adjustment, slide page, return, application program also can be by once pressing a piezoelectricity module 30 Or a piezoelectricity module 30 is repeatedly pressed to realize.

In this way, user by a piezoelectricity module 30 is pressed once or continuously press multiple touch control operation i.e. can be achieved The triggering of function services.

In some embodiments, the quantity of piezoelectricity module 30 includes multiple, and touch control operation includes：User presses more at the same time A piezoelectricity module 30；And/or user once presses multiple piezoelectricity modules 30 with the second preset interval time timesharing.

In other words, during user's touch control operation piezoelectricity module 30, can once at the same time press multiple piezoelectricity modules 30 and make by The pressing dynamics of each piezoelectricity module 30 or compressing time is pressed to meet trigger condition at the same time to trigger corresponding function services；Or Person, during user's touch control operation piezoelectricity module 30, can timesharing repeatedly press multiple piezoelectricity modules 30 and make to press piezoelectricity module every time 30 pressing dynamics or compressing time are satisfied by trigger condition to trigger corresponding function services, wherein, it is adjacent to press it twice Between time interval be the second prefixed time interval, the value of the second prefixed time interval should not be too large, for example, second it is default when Between the value that is spaced can be that 0.01s, 0.05s, 0.1s are equivalent.

Specifically, the correspondence between touch control operation and function services is illustrated by taking mobile phone as an example.Wherein, with user towards Exemplified by the display screen 201 of mobile phone, it is provided with the side wall 14 on the right side of mobile phone for sensing the touch control operation of user to realize ON/OFF Two piezoelectricity modules 30 of machine, are provided with for sensing the touch control operation of user to realize volume tune on the side wall 14 on the left of mobile phone Four piezoelectricity modules 30 of section.For example, when mobile phone is in off-mode, user can press two pressures of right sidewall 14 at the same time Electric module 30 simultaneously makes the pressing dynamics of the two piezoelectricity modules 30 of pressing i.e. triggerable simultaneously greater than or during equal to preset pressure value Mobile phone power-on；When mobile phone is in open state, user can press at the same time two piezoelectricity modules 30 of right sidewall 14 and make by Press the pressing dynamics of the two piezoelectricity modules 30 i.e. triggerable mobile phone shutdown simultaneously greater than or during equal to preset pressure value.Or example Such as, when mobile phone is in off-mode, user can press two piezoelectricity modules 30 of right sidewall 14 at the same time and make piezoelectricity module 30 compressing time triggerable mobile phone power-on simultaneously greater than or during equal to preset time；When mobile phone is in open state, use Family can press two piezoelectricity modules 30 of right sidewall 14 at the same time and make the compressing time of the two piezoelectricity modules 30 of pressing at the same time It can trigger mobile phone shutdown during more than or equal to preset time.Or for example；When mobile phone is in open state, user is left in mobile phone Perform slide from top to bottom on the side wall 14 of side, during slide user's finger can timesharing be pressed into left side successively Four piezoelectricity modules 30 on side wall 14, and the pressing dynamics for pressing piezoelectricity module 30 are all higher than or equal to preset pressure value, this When can trigger reduce volume function services；User performs slide from the bottom to top on the side wall 14 on the left of mobile phone, User's finger can be pressed into four piezoelectricity modules 30 on the side wall 14 of left side successively during slide, and press piezoelectricity module 30 pressing dynamics are all higher than or equal to preset pressure value, can trigger the function services of increase volume at this time.Or for example, work as hand When machine is in open state, user from top to bottom quickly clicks four piezoelectricity modules 30 successively on the side wall 14 on the left of mobile phone, And the pressing dynamics of pressing piezoelectricity module 30 every time are made to be all higher than or equal to preset pressure value, can trigger reduce volume at this time Function services；User quickly clicks four piezoelectricity modules 30 successively from the bottom to top on the side wall 14 on the left of mobile phone, and makes every time The pressing dynamics of pressing piezoelectricity module 30 are all higher than or during equal to preset pressure values, can trigger the function clothes of increase volume at this time Business.

In some embodiments, the touch control operation direction (for example, from top to bottom, from the bottom to top etc.) of user can be by Reason device 202 is perceived.In other words, processor 202 can be used for obtaining user's touch control operation piezoelectricity module 30 by electric signal Pressure, the direction of touch control operation is judged according to the change of the position of piezoelectricity module 30, and true according to the direction of touch control operation Fixed function services corresponding with the direction of touch control operation.

Specifically, multiple piezoelectricity modules 30 are used to cooperate with the touch control operation for sensing user to realize touching for corresponding function service During hair, since the position that each piezoelectricity module 30 is set is different, when piezoelectricity module 30 senses the touch control operation of user simultaneously When the electric signal of generation is sent to processor 202 via circuit main board 60, processor 202 is according to the multiple electric signals received Sequencing be that can determine whether user operates successively during pressing the position of piezoelectricity module 30, so that it is determined that place's touch control operation Direction.In this way, user can realize volume adjustment, cunning by way of sliding or timesharing repeatedly presses multiple piezoelectricity modules 30 The function services such as dynamic page turning.

In some embodiments, processor 202 is additionally operable to obtain user's touch control operation piezoelectricity module 30 by electric signal Pressure, and when pressure falls into different pre-set pressure ranges, trigger function corresponding from different pre-set pressure ranges Service.

In other words, same piezoelectricity module 30 or multiple piezoelectricity modules 30 for cooperateing with triggering identical function service can lead to The difference of the pressure of user's touch control operation is crossed to trigger different function services.Specifically, for example, a piezoelectricity module 30 can be real Existing machine open/close and the function services of application program switching, then it is pre- at first to fall as user in the case where mobile phone is in open state If the first pressure in pressure limit can trigger the function services of application program switching when pressing above-mentioned piezoelectricity module 30, at this time Application program switch window can be shown on display screen 201；When user with fall the second pressure in the second pre-set pressure range by Press the function services that can trigger shutdown during above-mentioned piezoelectricity module 30.Wherein, first pressure is less than second pressure and first pressure More than preset pressure value, the maximum pressure value of the first pre-set pressure range be less than the minimum pressure values of the second pre-set pressure range and The minimum pressure values of first pre-set pressure range are more than preset pressure value.For another example two piezoelectricity modules 30 can at the same time by by The function services returned with application program switching are realized in the state of pressure, then is in open state in mobile phone and mobile phone is not in leading When under interface, when user presses above-mentioned two piezoelectricity module 30 at the same time to fall the first pressure in the first pre-set pressure range The function services of application program switching are can trigger, can show the window of reference program switching on display screen 201 at this time；Work as user When pressing two above-mentioned piezoelectricity modules 30 at the same time to fall the second pressure in the second pre-set pressure range, you can triggering returns Function services.

In this way, piezoelectricity module 30 can trigger different function services according to the difference of pressing dynamics, piezoelectricity module 30 is answered With the manufacture cost for reducing housing unit 100 and electronic device 200.
