Abstract

The utility model discloses doorbell transference telephone, comprising a telephone and a doorbell. The utility model is characterized in that: a telephone circuit, an earpiece talkback circuit and a doorbell talking circuit are arranged in the telephone shell and a microphone, a loudspeaker and a button are arranged in the doorbell shell; the telephone circuit consists of a microprocessor, a ringing circuit, an amplifying circuit, a switching circuit, a communicative circuit and a keyboard, the talking circuit, the earpiece talkback circuit and the doorbell talking circuit are mutually communicated and respectively connected with the microprocessor and the talking circuit and the earpiece talkback circuit are connected with the earpiece. The doorbell is arranged outside the door and is connected with the telephone through a conductor. When somebody is at home, the host can talk with the guests outside the door through the telephone and the doorbell; when nobody is at home, the doorbell dials the number the host preset and the host can talk with the guests through the telephone line. The utility model has the advantages of simple circuit, stable performance, reliable work, low cost, etc.

Description

Doorbell shifts phone

Technical field

The utility model relates to the communication technology in the electricity field, and specifically a kind of doorbell shifts phone.

Background technology

Existing doorbell generally is to press the button as the guest, and doorbell will send music and tell owner to have the guest to come or carry out inside and outside intercommunication by talkback unit that when nobody home, doorbell has just lost effect.

Summary of the invention

Problem to be solved in the utility model is that doorbell and telephone communication are united two into one, and reduces integrated cost, and multiple functional, adaptability is strong; Man-hour is arranged among the manager, and owner can be by phone and doorbell and guest's intercommunication; Among the manager nobody the time, doorbell can be dialed the phone that owner presets automatically, owner and guest can converse by telephone line, improve the applicability of doorbell so greatly.

Concrete technical scheme of the present utility model is:

Doorbell shifts phone and comprises telephone set and doorbell, and characteristics are to be provided with telephone set network, receiver talkback circuit, doorbell speaking circuit in the telephone case, are provided with miaow head, loud speaker and button in the doorbell housing; Telephone set network is made up of microprocessor, ringing circuit, amplifying circuit, switching circuit, speaking circuit and keyboard, ringing circuit is connected with switching circuit, switching circuit, amplifying circuit, speaking circuit and keyboard connect microprocessor, speaking circuit, receiver talkback circuit, doorbell speaking circuit are connected mutually and are connected with microprocessor respectively, and speaking circuit, receiver talkback circuit are answered tube.Doorbell is installed in outdoors, connects with telephone set by lead.Adopt 220/9V AC/DC transformer-supplied, when mains failure, doorbell circuit will quit work, and telephony feature is still normal.

The utility model complete machine has that circuit is simple, stable performance, reliable operation, low cost and other advantages.
