Summary of the invention
Sensitivity and the consistency relatively poor problem of the utility model in order to solve the induced key of each on the television set in the prior art, a kind of novel touch-induction-type press-key structure is provided, make the sensitivity of induced key break away from the influence of structure and assembling, efficiently solve consistency problem.
For solving the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of touch-induction-type button of television set, the electrostatic induction terminal that comprises the electrostatic induction chip and be electrically connected with it, be disposed with conducting foam layer and insulation material layer on described electrostatic induction terminal, wherein, the conducting foam layer contacts with the electrostatic induction terminal; Between described conducting foam layer and insulation material layer, be equipped with the conductive aluminum foil layer.
Described conductive aluminum foil layer sticks on the back side of insulation material layer, contacts with the conducting foam layer, and the conducting foam layer sticks on the electrostatic induction terminal; The front of insulation material layer is for being subjected to by the position, wherein, is subjected to by the position transparently, and remainder is coated with opaque paint.Described insulation material layer is the acrylic material layer.
The circuit structure of described touch-induction-type button is: the electrostatic induction terminal is electrically connected on the input of electrostatic induction chip by lead, the input of described electrostatic induction chip passes through capacity earth, output connects the television set master chip on the one hand, connects DC power supply by pull-up resistor on the other hand.Described electrostatic induction terminal includes 6, respectively 6 function buttons of corresponding television set.It is the capacitive induction integrated chip realization of TS02 that described electrostatic induction chip adopts a model.
Compared with prior art, advantage of the present utility model and good effect are: the utility model is by adding one deck conductive aluminum foil layer between the conducting foam layer of each touch-induction-type button and insulation material layer, with the conductive aluminum foil laminating on insulation material layer, as long as the conducting foam layer contacts with the conductive aluminum foil layer, button just can operate as normal, and this is easy to accomplish in assembling.The aluminium foil size has determined the sensitivity of button, can be by regulating the sensitivity of aluminium foil size adjustment button, be easy to make the sensitivity of a plurality of buttons to accomplish unanimity, thereby make the sensitivity of induced key break away from the influence of television structure and assembling, efficiently solve consistency problem.Touch-induction-type press-key structure of the present utility model is simple, and sensitivity is adjustable, can accelerate the development rate of tv product greatly, improves operation stability of equipment.
