Abstract
The utility model relates to a message doorbell, which belongs to the electronic field for civil life, and is characterized in that: a pick-up device is connected between a pin 1 and a pin 2 of a language processor; a pin 3 of the language processor is connected with the cathode of a DC supply; a pin 5 of the language processor and a trigger end of a music integrated circuit are connected with the anode of the DC supply via a player button switch; a pin 4 of the language processor is connected with the anode of the DC supply via two record button switches connected in parallel; a pin 6 of the language processor is connected with a slide switch; a music signal output end of the music integrated circuit is connected with the slide switch; a loudspeaker is connected between the middle end of the slide switch and the cathode of the DC supply. The doorbell not only can timely tell host the knock of visitors when the host is at home, but also can leave messages to the visitors when the host is not in, or facilitate visitors to leave messages; the utility model has the advantages of simple circuit, multiple functions, low cost and practicality.
Description
Affiliated technical field
The utility model relates to a kind of message leaving door bell, belongs to the domestic life electronic applications.
Background technology
At present, the doorbell series products, numerous in variety, but function singleness for resident family, not only will make the time marquis who oneself is in, and knows that in time the visitor knocks at the door, but also wants to make the time marquis who oneself leaves home, whom knows why thing is struck and move into one's husband's household upon marriage.
Summary of the invention
The purpose of this utility model provides a kind of message leaving door bell, and the time marquis that it not only can make resident family be in knows that in time the visitor knocks at the door, and the time marquis that resident family is left home, and leaves word for the visitor, and the visitor is left a message.
The purpose of this utility model is achieved in that circuit is by language processor. music integrated circuit. and acoustic pickup. loudspeaker etc. are formed, it is characterized in that: connect acoustic pickup between 1 pin of language processor and 2 pin, 3 pin of language processor connect the negative pole of direct supply, 5 pin of language processor and music integrated circuit trigger end connect the positive pole of direct supply by the player button switch, 4 pin of language processor connect the positive pole of direct supply by the record button switch of two parallel connections, 6 pin of language processor link to each other with slide switch, the music signal output terminal of music integrated circuit links to each other with slide switch, connect loudspeaker between slide switch middle-end and the dc power cathode, the model of language processor is: VTV001B, with acoustic pickup. the player button switch. a record button switch is placed in time shell, loudspeaker place inboard, main shell sound transmission aperture position, and other circuit elements device is placed in the main shell.
Because adopt technique scheme, the advantage and the good effect that are had are: circuit is simple, function is many, inexpensive practicality.
