Abstract
The utility model relates to an electronic doorbell capable of informing a visiting guest that a host is not at home or is at rest and preventing the visiting guest from disturbing the host. The utility model comprises a doorbell button arranged on a gate and a doorbell sound generator arranged indoors. The utility model is characterized in that a loudspeaker is arranged on the gate, and a single-pole triple throw switch, a disturbance preventing voice circuit, a going-out information circuit and a power amplification circuit are arranged indoors. Compared with the prior doorbells, the utility model is additionally provided with the function of supplying information to a visitor, so the affair handling efficiency of the visitor is raised and unnecessary trouble for the host is avoided.
Description
The utility model relates to a kind of doorbell, particularly a kind of doorbell that master message can be provided to the visitor.
Existing doorbell can only play the effect of guest notice, when owner need have a rest or during busy going out, can not tell owner's guest information.This doorbell brings some trouble can for owner and guest, for example, influences owner's rest or the guest is at a loss.
The purpose of this utility model provides a kind of electronic door bell that can overcome above-mentioned defective, and it can notify the guest " owner has a rest " when owner needs rest.Make doorbell not send sound simultaneously, when owner does of short duration going out, notify the guest " owner goes out, returns " for a moment.
The technical solution of the utility model is, a bell button is set on the gate, a doorbell acoustic generator is set in doors, it is characterized in that, a loudspeaker also is set on the gate, a single-pole triple-throw (SPTT) switch also is set in doors, an interruption-free sound circuit, a going-out information sound circuit and a power amplification circuit; One end of the movable contact of single-pole triple-throw (SPTT) switch and battery joins, and three breaks join with a power end of doorbell acoustic generator, interruption-free sound circuit, going-out information sound circuit respectively; The output terminal of interruption-free sound circuit, going-out information sound circuit and the input end of power amplifier join, the loudspeaker that is provided with on the output terminal of power amplifier and the gate joins, and bell button is serially connected between the trigger end of battery one end and interruption-free sound circuit, going-out information sound circuit, doorbell acoustic generator.Single-pole triple-throw (SPTT) switch of the present utility model is actually a state setting switch, the working power of controlling interruption-free sound circuit, going-out information sound circuit, doorbell acoustic generator respectively inserts, make one of them work, owner can receive guest's doorbell signal or notify the guest certain information by the position of single-pole triple-throw (SPTT) switch is set.
The utility model is compared with existing doorbell, has increased to notify the visitor function of two kinds of information, can improve the efficient that the visitor handles affairs.
Fig. 1 is the circuit diagram of an embodiment of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in detail.
The utility model is connected by lead between two parts in two sub-sections, and one of them part is bell button N and the loudspeaker Y that is located on the gate
1, another part is the single-pole triple-throw (SPTT) switch that is located within doors, interruption-free sound circuit, going-out information circuit, power amplifier and doorbell acoustic generator and battery E.This part has a housing protection.
The interruption-free sound circuit is by speech chip IC
1Constitute the voice signal of internal memory " owner has a rest, and Do not disturb ".IC
1Model can be the speech chip of TP11 series, as YP1100K, its pin 1 is a trigger end, connects the anode of battery E by bell button N; Pin 2 joins for the break 1 of power supply input anode and single-pole triple-throw (SPTT) K switch; Pin 3 joins for the negative pole of power supply input negative terminal and battery: pin 4 passes through capacitor C for output terminal
1Join with the input end of power amplifier.
The going-out information circuit is by speech chip IC
2Constitute the voice signal of internal memory " owner goes out, please comes after a while again " and so on.IC
2Model can be the speech chip of TP11 series also, as TP1100K, its pin 1 is a trigger end, connects the anode of battery E by bell button N; Pin 2 is power supply input anode, joins with the break 2 of single-pole triple-throw (SPTT) K switch; Pin 3 joins for the negative pole of power supply input negative terminal and battery; Pin 4 is an output terminal, passes through capacitor C
2Join with the input end of power amplifier.
Power amplifier is by resistance R
1-R
4, capacitor C
3, triode BG1 constitutes, and is a typical expelling plate amplifier altogether, its output terminal and loudspeaker Y
1Join.
Doorbell sound acoustical generator is the musical film IC of KD48 by model
3, resistance R
5, triode BG
2, loudspeaker Y
2Constitute.Be a common musical sound acoustical generator, be usually used in electronic door bell.The break 3 of the power supply input anode order cutter three throw switch K of this doorbell sound acoustical generator, its power-termination battery negative terminal.Because IC
3Therefore musical film for negative potential triggers has connect an inverter ic between trigger end (pin 1) and button N
4, so that the positive level that triggers becomes negative level.
As seen from the figure, the anode of the movable contact of single-pole triple-throw (SPTT) K switch and battery E joins, and respectively with IC
1, IC
2, IC
3Power supply input anode join, like this, interruption-free sound circuit, going-out information sound circuit, doorbell acoustic generator at a time can only have a job, and IC
1, IC
2, IC
3Trigger end then simultaneously by bell button N control, therefore, when pressing bell button, can only have a chip of above-mentioned work to be triggered and output signal, for example work as IC
1Positive supply when inserting, have only IC
1Be triggered, the signal of " owner has a rest, and Do not disturb " of its internal memory is sent to loudspeaker Y by the power amplifier amplification
1, other signal is not output then.Owner just can realize that by the position that the single-pole triple-throw (SPTT) K switch is set the utility model notifies the goal of the invention of visitor's information and interruption-free like this.
Claims (1)
1, a kind of electronic door bell, comprise bell button that is located on the gate and the doorbell sound acoustical generator that is located within doors, it is characterized in that: a loudspeaker also is set on the gate, a single-pole triple-throw (SPTT) switch also is set in doors, an interruption-free sound circuit, a going-out information sound circuit and a power amplification circuit; One end of the movable contact of single-pole triple-throw (SPTT) switch and battery joins, and three breaks join with a power end of doorbell acoustic generator, interruption-free sound circuit, going-out information sound circuit respectively; The output terminal of interruption-free sound circuit, going-out information sound circuit and the input end of power amplifier join, the loudspeaker that is provided with on the output terminal of power amplifier and the gate joins, and bell button is serially connected between the trigger end of battery one end and interruption-free sound circuit, going-out information sound circuit, doorbell acoustic generator.
