4 and 15 are please referred to Fig.1, in some embodiments, the substrate 23 of the above embodiment includes base material 232 and formed Lead 234 on base material 232, lead 234 are electrically connected with multiple piezoelectric elements 21.Specifically, piezoelectricity module 20 includes top Face 25, bottom surface 26 and side 27, top surface 25 are located at opposite both sides with bottom surface 26, and side 27 connects around top surface 25 and with top surface 25 Connect.Compared to piezoelectric element 21, base material 232 is located at close to the side of bottom surface 26.A part for lead 234 is formed in bottom surface 26 On, a part for lead 234 is electrically connected through base material 232 and with the piezoelectric element 21 on base material 232.Work as housing unit 100 when including circuit board 30, the bottom surface 26 of piezoelectricity module 20 be arranged on circuit board 30 and make lead 234 with circuit board 30 Circuit is electrically connected；When housing unit 100 includes circuit 40, the bottom surface 26 of piezoelectricity module 20 is arranged on inner surface 142 and makes Lead 234 is electrically connected with circuit 40；Alternatively, the top surface 25 of piezoelectricity module 20 is arranged on inner surface 142, piezoelectricity module 20 passes through Lead 234 is connected with other electronic components (for example, circuit main board 60) in electronic device 200.Multiple pressures of present embodiment Electric device 21 and insulating materials 22 are respectively formed on substrate 22, easy to which multiple piezoelectric elements 21 and insulating materials 22 are produced on base On plate 23, and make piezoelectric element 21 and insulating materials 22 more smooth, the structure of piezoelectricity module 20 is more stablized.Further, By setting the lead 234 being electrically connected with piezoelectric element 21 on base material 232, easy to be laid out the electrical connection of piezoelectricity module 20 again The position of terminal, consequently facilitating piezoelectricity module 20 is electrically connected with other electronic components (for example, circuit board 30), and then is easy to piezoelectricity Module 20 is installed on inner surface 142.In some embodiments, the quantity of lead 234 can be more, for example, each pressure Electric device 21 corresponds to two leads 234, which connects two connecting pins of the piezoelectric element 21 respectively.

Referring again to Fig. 7, in some embodiments, electronic device 200 may also include processor 202.Processor 202 is used Function services corresponding with the touch control operation of user are triggered in the electric signal produced according to piezoelectricity module 20.Function services include Machine open/close, volume adjustment, slide page, return, application program switching in any one or more.Wherein, volume adjustment bag Include increase volume and reduce volume.

In other words, function services can only include machine open/close, volume adjustment, slide page, return, application program is cut One kind in changing；Alternatively, function services can include both machine open/close and volume adjustment, volume adjustment at the same time and slide page The two, return and application program switching the two, slide page and both returning etc.；Alternatively, function services can at the same time include open/ Shutdown, volume adjustment and the three that slides page, machine open/close, slide page and application program switching three, volume adjustment, return Switch three etc. with application program；Alternatively, function services can include machine open/close, volume adjustment at the same time, slide page, return With application program switching.

In this way, the corresponding multiple function services of physical button are triggered by touch-control piezoelectricity module 20 so that electricity Sub-device 200 can integrated design, lift waterproof and anti-dust performance, increase the installation space of display screen 201.

In some embodiments, when piezoelectricity module 20 is subject to external force effect to deform upon and produces the electric signal of touch-control When, triggering the trigger condition of function services corresponding with the touch control operation of user includes the pressing force that user presses piezoelectricity module 20 Degree is greater than or equal to preset pressure value, and/or the compressing time of user's pressing piezoelectricity module 20 is greater than or equal to preset time.

In other words, piezoelectricity module 20 needs to meet that certain trigger condition could be touched after sensing the touch control operation of user Send out function services corresponding.Trigger condition can be that the dynamics that piezoelectricity module 20 is pressed in user is greater than or equal to preset pressure value When ability Trigger Function service；Either just touched when the compressing time that user presses piezoelectricity module 20 is greater than or equal to preset time Send out function services；The pressing dynamics that piezoelectricity module 20 is either pressed in user are greater than or equal to preset pressure value, and user presses Press piezoelectricity module 20 compressing time be more than preset time or equal to when ability Trigger Function service；Or in electronic device 200 The 20 Trigger Function service of a part of piezoelectricity module trigger condition be user press piezoelectricity module 20 pressing dynamics be more than or Equal to preset pressure value, the trigger condition of 20 Trigger Function service of another part piezoelectricity module is that user presses piezoelectricity module 20 Compressing time is greater than or equal to preset time.

By taking mobile phone as an example, user prevents mobile phone from falling using during mobile phone sometimes for the side wall 14 for gently holding mobile phone usually Fall, at this time, piezoelectricity module 20 can still sense the touch control operation of user, but actually user does not think Trigger Function service. Therefore, to prevent the situation of user's false triggering, set preset pressure value or with the trigger condition of preset time can to avoid because with The problem of maloperation at family causes function services to be triggered, improves the usage experience of user.

In some embodiments, touch control operation includes：User once presses piezoelectricity module 20；And/or user is with first Preset interval time repeatedly presses piezoelectricity module 20.

In other words, during user's touch control operation piezoelectricity module 20, can be once press a piezoelectricity module 20 and make by Surging or compressing time meet trigger condition to trigger corresponding function services；Alternatively, user's touch control operation piezoelectricity module 20 When, it can be one piezoelectricity module 20 of multiple pressing and make the pressing dynamics of pressing piezoelectricity module 20 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 20 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 20 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 20 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 20 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 20 of machine open/close and making to press piezoelectricity every time The pressing dynamics of module 20 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 20 of machine open/close and make the pressing dynamics of pressing piezoelectricity module 20 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 20 relevant with machine open/close and making pressing piezoelectricity module 20 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 20 and make pressing piezoelectricity module 20 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 20 Or a piezoelectricity module 20 is repeatedly pressed to realize.

In this way, user by a piezoelectricity module 20 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 20 includes multiple, and touch control operation includes：User presses more at the same time A piezoelectricity module 20；And/or user once presses multiple piezoelectricity modules 20 with the second preset interval time timesharing.

In other words, during user's touch control operation piezoelectricity module 20, can once at the same time press multiple piezoelectricity modules 20 and make by The pressing dynamics of each piezoelectricity module 20 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 20, can timesharing repeatedly press multiple piezoelectricity modules 20 and make to press piezoelectricity module every time 20 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 20 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 20 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 20 simultaneously makes the pressing dynamics of the two piezoelectricity modules 20 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 20 of right sidewall 14 and make by Press the pressing dynamics of the two piezoelectricity modules 20 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 20 of right sidewall 14 at the same time and make piezoelectricity module 20 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 20 of right sidewall 14 at the same time and make the compressing time of the two piezoelectricity modules 20 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 20 on side wall 14, and the pressing dynamics for pressing piezoelectricity module 20 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 20 on the side wall 14 of left side successively during slide, and press piezoelectricity module 20 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 20 successively on the side wall 14 on the left of mobile phone, And the pressing dynamics of pressing piezoelectricity module 20 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 20 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 20 are all higher than or during equal to preset pressure values, can trigger the function clothes of increase volume at this time Business.

Similarly, volume adjustment, slide page, return, application program switching function services can by and meanwhile press Multiple piezoelectricity modules 20 are realized.In addition, the function services to slide page can also press multiple piezoelectricity modules 20 successively by timesharing Realize.

In this way, user by the multiple piezoelectricity modules 20 of touch control operation to realize the triggering of function services.

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 20 by electric signal Pressure, the direction of touch control operation is judged according to the change of the position of piezoelectricity module 20, 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 20 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 20 is set is different, when piezoelectricity module 20 senses the touch control operation of user simultaneously When the electric signal of generation is sent to processor 202 via circuit board 30, processor 202 is according to the multiple electric signals received Sequencing is the position of the piezoelectricity module 20 that user operates successively during can determine whether to press, so that it is determined that place's touch control operation Direction.In this way, user can realize volume adjustment by way of sliding or timesharing repeatedly presses multiple piezoelectricity modules 20, slide The function services such as page turning.

In some embodiments, processor 202 is additionally operable to obtain user's touch control operation piezoelectricity module 20 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 20 or multiple piezoelectricity modules 20 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 20 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 20, 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 20.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 20 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 20 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 20 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 20 can trigger different function services according to the difference of pressing dynamics, piezoelectricity module 20 is answered With the manufacture cost for reducing housing unit 100 and electronic device 200.
