[background technology]
Recently, along with Google, in the mobile phone manufacturer such as emerging (ZTE) in succession shown oneself intelligent modularized mobile phone concept, modular mobile phone concept is known by people gradually.So-called mobile module, as the term suggests refer to that the critical piece of mobile phone can be matched voluntarily and be changed by user, just as past computer DIY prevailing assembles a computer.
Modular mobile phone, it can pile up and disassemble again as building blocks, be therefore otherwise known as by " building blocks mobile phone ", so, its require each main function components can be as building blocks random disassembling, assembling and replacing.But the transducer of the actuator of existing driving mobile phone screen vibration and reception screen vibrational feedback is to be all but directly adhesively fixed on screen, and this fixed structure must limit the development of current modular mobile phone.
[utility model content]
The purpose of this utility model is the electronic equipment that a kind of piezo electric module is provided and applies this piezo electric module, it has solved the transducer that drives the actuator of mobile phone screen vibration in modular mobile phone and receive screen vibrational feedback is to be all directly adhesively fixed on screen, thereby has limited the technical problem of the development of current modular mobile phone.
In order to solve the problems of the technologies described above, the utility model provides a kind of piezo electric module, its vibrational feedback for driving screen vibration or receiving screen, it comprises a housing with receiving space, accommodate and be fixed in described housing and have the piezoelectric vibration piece of vibration section and for realizing the conductive contact of described piezo electric module and external circuit electric connection, described piezo electric module also comprises ennation, described vibration section is fixed in this ennation one end, and it is outer so that butt screen that described housing is extended in its other one end.
Preferably, the position of the corresponding described ennation of described housing is provided with the first through hole, and described ennation extends from this first through hole.
Preferably, described conductive contact is arranged on described housing.
An electronic equipment, this electronic apparatus application piezo electric module as above.
Preferably, this electronic equipment comprises a mainboard and establishes fixing screen with described mainboard is folded, and described piezo electric module is replaceable to be fixed on this mainboard and to drive described screen vibration or receive the vibrational feedback of this screen.
Preferably, this mainboard is provided with the second through hole, the ennation of this piezo electric module through this second through hole in case with described screen butt.
The beneficial effects of the utility model are: the electronic equipment that the utility model provides a kind of piezo electric module and applied this piezo electric module, it can arbitrarily disassemble replacing piezo electric module according to the actual requirements, not only assembling is simple, and piezo electric module can design separately and produce, greatly reduce and produce and design cost.

[embodiment]
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As illustrated in fig. 1 and 2; the utility model provides a kind of piezo electric module 100; it comprises a housing 2 with receiving space 1, accommodate and be fixed in described housing 2 and have the piezoelectric vibration piece 3 of vibration section 30 and one end is fixed on described vibration section 30 and to extend described housing 2 outer so that the ennation 4 of butt screen in one end in addition; this ennation 4 can be that direct butt contacts described screen; also can other element be set between ennation 4 and screen and realize indirect butt, but this all belongs to the scope that the utility model is protected.For described piezoelectric vibration piece 3 can be fixed in described housing 2 easily, described piezo electric module 100 is also provided with the supporter 5 being contained in described receiving space 1, described piezoelectric vibration piece 3 is fixed on described supporter 5, piezoelectric vibration piece 3 can maintain a certain distance with the diapire of described housing 2 like this, is the reserved enough oscillation spaces in described vibration section 30.
Described piezo electric module 100 is for driving the vibrational feedback of screen vibration or reception screen, when described piezo electric module 100 receives the driving signal of external circuit, the vibration section 30 of described piezoelectric vibration piece 3 produces vibration, and ennation 4 is fixed on this vibration section 30 and is connected to screen, therefore, described piezo electric module 100 will promote described screen and jointly vibrate, in like manner, in the time need to receiving the vibrational feedback of screen, the vibration section 30 that screen vibration will promote described piezoelectric vibration piece 3 vibrates jointly, due to inverse piezoelectric effect, the vibrational feedback of screen will be converted into the signal of telecommunication and be exported to external circuit by described piezoelectric vibration piece 3.
The position of the corresponding described ennation 4 of described housing 2 is provided with the first through hole 20, and described ennation 4 extends from this first through hole 20.This first through hole 20 not only extends for described ennation 4, and it can be located described ennation 4 and this ennation 4 can be vibrated accurately and can not produce and wave.
Described piezo electric module 100 also comprises the conductive contact (not indicating) being electrically connected for realizing described piezo electric module 100 and external circuit, and described conductive contact is preferably arranged on described housing 2.This conductive contact is inner and piezoelectric vibration piece 3 electric connections at this housing 2, and it is outside for being electrically connected with external circuit at housing 2.This conductive contact may be as the jack shape on socket, also may or be arranged at the conductive welding disk on housing 2 as the metal column shape on socket, and its function is only used to realize described piezo electric module 100 and is electrically connected with external circuit.
In conjunction with shown in Fig. 3, the utility model also provides a kind of electronic equipment 200 again, this electronic equipment 200 application piezo electric module 100 as above.This electronic equipment 200 comprises a mainboard 6, folds and establish fixing screen 7 and a bonnet 8 with described mainboard 6.Described piezo electric module 100 is replaceable to be fixed on this mainboard 6 and to drive described screen 7 to vibrate or receive the vibrational feedback of this screen 7.Replaceable referring in the situation that not destroying both physics, mechanical structure, can utilize craft or instrument that one of them is replaced, and as being fixed, utilizing buckle structure to be fixed by grafting between the two, or utilizes the instruments such as elastic clip to fix.
Described piezo electric module 100 is electrically connected by the conductive contact on its housing 2 and mainboard 6, is also provided with the second through hole 60 on this mainboard 6, the ennation 4 of this piezo electric module 100 pass this second through hole 60 in case with described screen 7 butts.
The piezo electric module 100 that the utility model provides and the electronic equipment 200 of applying this piezo electric module 100, it can arbitrarily be disassembled according to the actual requirements and change piezo electric module 100, not only assembling is simple, and piezo electric module 100 can design separately and produce, and greatly reduces and produces and design cost.
Above-described is only better embodiment of the present utility model; at this, it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
