Abstract
The utility model discloses a multifunctional computer keyboard with the functions of lightening and mobile phone prompt; lightening bodies are arranged at the corresponding lower part of each key; the lightening bodies are connected with membrane switches; the lightening bodies at the lower parts of the keys of the left side of the keyboard are connected with an incoming call prompt circuit. The utility model is characterized in that the lightening bodies, other circuit component carriers and a support body of the membrane switches are together pasted and arranged on a PCB plate. The utility model has the advantages that the multifunctional computer keyboard adopts the PCB plate to skillfully integrate the component carriers and the support body of the membrane switches; the utility model simplifies manufacture process, improves reliability and stability, and reduces the manufacture cost.
Description
Technical field
The utility model relates to a kind of computor-keyboard, refers in particular to a kind of multifunction computer keyboard with luminous and incoming call prompt of mobile phone.
Background technology
Traditional illuminated keyboard is to utilize light emitting diode or cold light panel as light source, connects light emitting diode to the wiring board of keyboard and place the back side of button to disperse light source with lead.Because it is fine and closely woven and complicated that keyboard wiring board or cold light panel components and parts in manufacturing process are arranged, performance was very unstable always when product used, and production cost is high always.
Summary of the invention
The purpose of this utility model is to overcome existing illuminated keyboard wiring board and exists and make complicated and more unsettled shortcomings, and a kind of multifunction computer keyboard of simple for production, stable performance is provided.
In order to achieve the above object, technical solution adopted in the utility model is: a kind of multifunction computer keyboard, below each button is corresponding, luminophor is housed, luminophor links to each other with thin film switch, the luminophor of keyboard left side numerical key below is linked to each other with the incoming call prompting circuit, it is characterized in that: luminophor and other circuit elements component carrier are mounted on the pcb board with the thin film switch supporter.
Described multifunction computer keyboard has also imported backlight and has combined with pcb board.
Described multifunction computer keyboard is built-in with antenna and function IC.
The beneficial effects of the utility model are, have adopted pcb board dexterously the supporter of components and parts carrier and thin film switch to be integrated, and have simplified manufacture craft, have improved reliability, stability, have reduced cost of manufacture.And adopted unique backlight technology and middle plate to synthesize, make the point-like photolysis of the luminophor light that nebulizes, backlight soft, brightness is evenly moderate, night and more square result of use the best, because built-in aerial and function IC, can sense keyboard 60CM cell phone incoming call signal on every side, the triggering flash lamp circuit comes flashing light and extinguishes.
Description of drawings
Fig. 1 is the utility model circuit structure schematic diagram
Embodiment
Further set forth below in conjunction with description of drawings embodiment of the present utility model, the utility model multi-purpose computer illuminated keyboard is by LED luminophor, power supply, unique backlight, the incoming call flashing circuit for lamp, built-in aerial TX forms, power supply is made up of DC5V power switch K1, luminophor is by D1-1～D1-17, D2-1～D2-15, D3-1～D3-15, D4-1～D4-14, D5-1～D5-14, D6-1～D6-12 forms.Wherein the circuit working principle is the voltage DC5V that connects with the mains, after power switch K1 connects, D1-1～D1-17 is through R1, D2-1～D2-15 is through R2, D3-1～D3-15 is through R3, and D4-1～D4-14 is through R4, and D5-1～D5-14 is through R5, D6-1～D6-12 is through the R6 current-sharing, light through the R7 current limliting jointly, high-frequency electromagnetic signal triggers control IC1 after the diode filter again, the IC controller is by pre-set programs exporting 5 tunnel control signals, D7-1～7-4 in the IC2 supervisory keyboard, D8-1～D8-4, D9-1～D9-3, D10-1～D10-3, D11-1～D11-2 is luminous carry out glittering.D1-1～D1-17, D2-1～D2-15, D3-1～D3-15, D4-1～D4-14, D5-1～D5-14, the light of D6-1～D6-12LED light source appears through backlight, make the point-like photolysis of the LED light that nebulizes owing to imported backlight, just backlight soft, brightness is evenly moderate, D1-1～D1-17, D2-1～D2-15, D3-1～D3-15, D4-1～D4-14, D5-1～D5-14, D6-1～D6-12, D7-1～7-4, D8-1～D8-4, D9-1～D9-3, D10-1～D10-3, D11-1～D11-2, R1～R12, IC1, IC2, all be mounted on the same pcb board, this pcb board is again the supporter of thin film switch simultaneously, and pcb board is combined into one with the carrier of components and parts and supporter two functions of thin film switch dexterously, simplified manufacture craft greatly, improved reliability of products, stability has reduced cost of manufacture.
