Abstract

The utility model discloses a noiseless mouse which comprises a shell, a circuit board and a roller, wherein the circuit board is arranged in the shell; the roller is located on the shell; and the mouse can be connected with a computer in a wired or wireless manner. The noiseless mouse is characterized in that: two piezoelectric films are arranged at positions which correspond to an original mechanical button on the shell; and a piezoelectric film signal processing circuit is arranged on the circuit board. In the utility model, the conversion between a mechanical signal and an electric signal is realized by using the macromolecular piezoelectric films; when the mouse is in a work mode, an operator only needs to lightly touch the piezoelectric films to cause the piezoelectric films to generate a small deformation; and via the deformation, voltage signals are generated in the piezoelectric films and then the click control of the mouse is realized, so that the noises generated by the mechanical button are prevented. As only a small elastic deformation is generated, the reaction is very sensitive. Moreover, the piezoelectric films are fused with the mouse shell into a whole, so that the dustproof function and the waterproof function of the mouse are increased. The noiseless mouse has the characteristics of silence, durability, dust prevention and water tightness; and the structure is simple and the cost is lower.

Description

A kind of noiseless mouse
Technical field
The utility model relates to a kind of mouse, relates in particular to a kind of noiseless mouse.
Background technology
The generation of mouse has made things convenient for the control of people to computing machine greatly; Each computing machine all be unable to do without mouse; What but institute disposed and sold on the current market is to be the mouse of right and left key contact with the microswitch mostly; The microswitch of this mouse is a kind of high-speed switch of exerting pressure and touching, and its principle of work is: outer mechanical force is used to move reed through actuated element (like button, push-piece, lever etc.) with masterpiece, and with energy accumulation after critical point; Produce snap action, make the terminal moving contact (normally open contact) of action reed clash into or break off (reason that produces " ticktack " sound) fast with fixed contact (normally closed interlock).After the acting force on the actuated element was removed, the action reed produced counteragent power.Reach the action critical point of reed when the actuated element reverse stroke after, instantaneous completion counteragent.Yet the serviceable life of microswitch is shorter, and can produce the button sound of " ticktack " when pressing right and left key when finger, in quiet office or very easily influence people's work and rest at one's side night.
Many noiseless mouses that improved have at present also appearred; Like the patent No. is the Chinese patent " a kind of noiseless mouse " of CN200720021781.8; It is characterized in that, remove the touch-switch on the mouse, sheet metal is set in the button bottom; Contact conducting or the disconnection that corresponding welding foot is realized circuit through sheet metal, to produce the action message of button.Though this structure is simple, long easy abrasion of sheet metal and welding foot time causes loose contact, influences the normal use of mouse.Also having the patent No. is the Chinese patent " noiseless mouse " of CN201020135486.7; Infrared module and infrared ray receiver module are set in mouse; The infrared module links to each other with circuit board, and the infrared ray receiver module links to each other with circuit board, and the silica gel mousebutton links to each other with shadow shield; Circuit board links to each other with mouse case through the circuit board pillar, and the silica gel mousebutton links to each other with mouse case.This mouse is the conversion that realizes push button signalling through infrared module.Though use noiselessness and life-span long, structure is complicated and cost is higher fully.
Piezoelectric film sensor is the sensor that utilizes the piezoelectric effect that produces behind some dielectric medium stress to process.So-called piezoelectric effect is meant when deformation (like crooked and flexible deformation) takes place in the external force effect that receives a certain direction some dielectric; Because the polarization phenomena of internal charge; Can produce the electric charge of opposite in sign on two surfaces of crystal, when external force was removed, electric charge disappeared.Macromolecule (like Kynoar etc.) piezoelectric membrane is extensively utilized with characteristics such as its light weight, softness, specific strength are high, wear-resisting, anticorrosive.
Summary of the invention
The utility model technical matters to be solved is the noiseless mouse that a kind of economy and durability is provided to the above-mentioned state of the art, utilizes piezoelectric membrane to realize the conversion of mechanical signal and electric signal, improves the shortcoming of existing mousebutton noise.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of noiseless mouse; Comprise housing, be located at the circuit board in the housing and be positioned at the roller on the housing; Said mouse can be connected with computer through wired or wireless mode; It is characterized in that: the position corresponding to original mechanical key on the said housing is provided with two piezoelectric membranes, and said circuit board is provided with the piezoelectric membrane signal processing circuit of cooperation.
As improvement; Said housing is to be involuted by upper shell and lower house; In the involutory cavity of upper shell and lower house, be provided with roller, circuit board and photoelectric sensor; Position corresponding to roller on the said upper shell offers the roller hole, and the position in the both sides in roller hole corresponding to original mechanical key forms the inner fovea part that is used to place piezoelectric membrane, and said piezoelectric membrane just in time is embedded in the inner fovea part; Its upper surface and upper shell form smooth plane, and through one be covered in the upper shell upper surface diaphragm fix.
As improvement, said roller, circuit board and photoelectric sensor are fixedly installed on the lower house.
Improve, said piezoelectric membrane is supported single-point or multi-touch function again.
At last, the mode that said MouseAcross is wireless excessively is connected with computer, in said housing, is provided with the battery compartment and corresponding radio data-transmission equipment that are used to place battery.
Compared with prior art, the advantage of the utility model is: abandoned the microswitch in the common mouse, adopted the macromolecule piezoelectric membrane to realize the conversion between mechanical signal and the electric signal; Utilize the direct piezo electric effect principle, when mouse was in running order, the operator only need touch piezoelectric membrane; Make it produce a miniature deformation; This deformation produces voltage signal in piezoelectric membrane, realize the click control of mouse, thus the noise of having avoided mechanical key to send.Owing to only need to produce a small elastic deformation, its reaction can be very sensitive.In addition, because piezoelectric membrane and mouse case combine together, can improve the dustproof and waterproof function of mouse.The utlity model has characteristics quiet, durable, dustproof and waterproof, the while is simple in structure, price is lower.
