The numerical type receives visitors, sees visitor out the speech door bell

Abstructs
This text introduces a kind of speech door bell that has to identify the bearer function in brief, in keeping with installed the usage before the door of the public places, such as guest house and market...etc..When someone enters the door, it would the manner ground send out to" welcome" the voice, someone go out then send out to" thanks for coming" automatically of send off the language, make person feel more warm.It is shot the type electric circuit, the language electric circuit by the double road infrared ray and steady press the electric circuit etc. constitute, explaining the work principle of each electric circuit.This text still introduced the function and the application of a machine of some main electronicses piece.
Key words: The numerical type, Infrared ray, The speech door bell, Receives visitors, sees visitor out
