Abstract

The utility model relates to a multifunctional door bell with a computer, which is composed of a sound generating circuit, a horn, a shell body, batteries, a dual-purpose button switch, etc. Because a special structure that the dual-purpose button switch is matched with two sound integrated circuits in the sound generating circuit is adopted, the utility model can send out the sound of 'ding-dong, hello, please open the door' in Chinese when the utility model is pressed by people; furthermore, the utility model can send out the two-tone of 'ding-dong' when family (or acquaintance) press the door bell; thereby, guests and the family can be obviously differentiated by the door bell with a computer. The utility model has the advantages of novel and reasonable structure, simple circuit, low cost and energy saving; furthermore, the utility model is suitable for various living rooms, such as, households, hotel guest rooms, etc.

Description

Door bell with computer

The utility model relates to a kind of doorbell, particularly a kind of multi-purpose computer doorbell.

Existing doorbell generally all can only send a kind of sound or music, and can not distinguish messenger is household or stranger, meets accident easily.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of two kinds of alternative sounds that can send respectively is provided, and is household or stranger's multi-purpose computer doorbell with differentiation.

The purpose of this utility model can reach by following measure: the utility model comprises sound generating circuit, loudspeaker, housing, battery, it is characterized in that: also have dual-purpose pushbutton switch, movable contact spring and button join in the pushbutton switch, fixed touching plate is fixed on the push-button socket, button keys can make movable contact spring contact with fixed touching plate, and rotate button movable contact spring is contacted with fixed touching plate.

The purpose of this utility model can also reach by following measure: the movable contact spring of pushbutton switch and battery E join in the sound generating circuit, the trigger end T2 of fixed touching plate and sound integrated circuit (IC) 2 joins, the trigger end T1 of fixed touching plate and sound integrated circuit (IC) 1 joins, the output terminal OUT1 of IC1 and triode BG1 base stage are joined, BG1 collector and triode BG2 base stage are joined, the output terminal OUT2 of IC2 and triode BG3 base stage are joined, and the collector of BG3 and BG2 base stage are joined.

Fig. 1 is an electrical schematic diagram of the present utility model;

Fig. 2 is a contour structures synoptic diagram of the present utility model;

Fig. 3 is the inner structure front elevation of pushbutton switch;

Fig. 4 is the inner structure vertical view of pushbutton switch.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1, Fig. 2, the utility model is made up of sound generating circuit 1, loudspeaker 2, housing 3, pushbutton switch 4, battery E etc.Sound generating circuit 1 is made up of sound integrated circuit (IC) 1, IC2, triode BG1～BG3, resistance R 1, R2, LED etc.IC1 is double-tone " ding-dong " module; IC2 is double-tone " ding-dong ", then is the module of national language female voice " you are good, please open the door ".The outward appearance of pushbutton switch 4 is the same with the common door bell button.

With reference to Fig. 3, Fig. 4, pushbutton switch 4 comprises movable contact spring 5, by key spring 7, fixed touching plate 8,9, push-button socket 10, spring 11, reference column 12, screw 13 etc.Movable contact spring 5 screws 13 join, and button spring 7 is contained between button 6 and the push-button socket 10; Fixed touching plate 8 and 9 is fixed on the push-button socket 10.

When the stranger uses, general button 6 downwards only all, at this moment, movable contact spring 5 contacts with fixed touching plate 8, and startup IC2 sends that " ding-dong, you are good! Please open the door " voice signal, amplify through BG3, BG2, drive the loudspeaker pronunciation; The head of a family on time, clockwise shearing button 6 makes movable contact spring 5 contact with fixed touching plate 9, starts IC1 and sends " ding-dong " voice signal, after BG1, BG2 amplify, drives the loudspeaker pronunciation.After loosing one's grip, movable contact spring 5 relies on the spacing of the pulling force of springs 11 and reference column 12, gets final product auto power off, sets back.During the doorbell pronunciation, LED and its synchronization flash in time point out the deaf-mute to find and distinguish messenger.IC1, IC2 all have auto-lock function, at ordinary times power consumption utmost point emblem.

The utility model has following advantage compared to existing technology:

1. can obviously distinguish household and stranger, can also in time point out the deaf-mute to find and distinguish messenger with the luminous tube of pronunciation synchronization flash, it be very convenient to use.

2. phone is simple, novel and reasonable structure, and it is loud to pronounce distinctly, briefly lucid and lively, saves electric energy, and cost is lower, is fit to family, hotel guest-room, office strategic point and all kinds of room and uses.
