Abstract

The utility model relates to a telephone with phonetical toll function, which comprises a frame and a mouthpiece. The frame is provided with a phone circuit of a toll integration chip which collects an incoming telegram display, a toll, a fluid indicating drive and a signal transmitting as whole. The utility model is characterized in that one end of the toll integration chip of the phone circuit switches to data output end, and a serial interface conveying data method is adopted to connect a speech chip. The telephone can report the dialing number and toll condition timely with sound, which is extremely convenient to be used and managed. The utility model is in particular suitable for the public telephone management with service to outside and has the advantages of good reliability and strong practicability.

Description

Voice charging phone

The utility model relates to telephone set and improve, especially a kind of voice charging phone with voice mode newspaper telephone expenses.

At present, the phone that charges on the market charges accurately because of it and other special function (immediate charging number, free code and special charge number can be set, can inquire about electricity and monthly fee etc.) is subjected to liking of user, a lot of phonebooths all are ready to spend money on one, as long as the expenses standard by local post and telecommunications office sets, the charging phone can be adjusted each conversation amount of money automatically and it is shown on LCDs, remove a series of loaded down with trivial details work such as user's calculating from, not only fast but also accurate.But, existing most phonebooth client is for convenience made a phone call, the telephone set direction is external, owner is sitting in the telephone wire porch, top of only seeing telephone set in the booth, can't see the LCDs of telephone set, owner will stand up after each client has made a call, with telephone set direction pendulum turnback, head stretches out just outward can see the conversation amount of money clearly, finishing watching the back makes a phone call for convenience of next client, also telephone set will be had again the rotations of 180 degree have so caused the inconvenience on using.

The purpose of this utility model is the deficiency that exists at above-mentioned liquid crystal display charging phone, and a kind of voice Charging telephone of the instant circular of situation and cost of the phone call that the user can be dialled is provided.

Voice Charging telephone of the present utility model, comprise: support and microphone, be provided with in the support and contain caller identification, charging, liquid and show the telephone circuit that drives, sends out number in the charging integrated chip of one, it is characterized in that: an end pin of the charging integrated chip of telephone circuit switches to data output end, and connects a speech chip with serial line interface transmission data mode; The power end of the speech chip power supply of answering the call, the speech output end of the speech chip power amplifier input of answering the call, the amplifier power supply control end of the speech chip amplifier power supply control end of answering the call.

The utility model voice Charging telephone is reasonable in design, and it can will dial and charging case is quoted immediately with voice, be very easy to use and manage.Especially be suitable for the public telephone management of externally service, the client is with hands-free making a phone call the time, and whenever by a number, the phone loud speaker can be quoted this number automatically.The client has played on-hook, when LCDs shows the conversation amount of money, loud speaker is quoted " conversation the amount of money * unit * angle * minute " at once, as long as you are on the telephone set next door, whichever orientation all can clearly be heard, the phone owner does not spend the institute of yet knowing of making a call at the onlooker family and makes a phone call and the amount of money of conversing when selling newspaper, cigarette, and can continue other work, economized a people who sees public telephone specially.Advantages such as this telephone set has good reliability, and is practical.

Concrete structure of the present utility model is provided in detail by the following drawings and embodiment.

Fig. 1 is the circuit diagram of voice Charging telephone.

Embodiment: the basic structure of voice Charging telephone is identical with the existing telephone machine, comprise: phone support, receiver and telephone circuit, comprise that from the visible telephone circuit of Fig. 1 one integrates caller identification, charging, liquid and shows the charging integrated chip A that drives, sends out number, described charging integrated chip A is the GS2208B integrated chip.Its difference is to have increased a speech chip B on the telephone circuit, described speech chip B is the GS5000 speech chip, adopt serial line interface to transmit data between the charging integrated chip A of speech chip B and telephone circuit, that is: the Data Control end VOLO with charging integrated chip A switches to data output end, and is connected with the address end OATA of speech chip B; The power end VDD of the speech chip B power supply of answering the call, the answer the call power amplifier input of circuit of the speech output end SPK of speech chip B, the answer the call amplifier power supply control end of circuit of the amplifier power supply control end BUSY of speech chip B, the earth terminal VSS of the speech chip B machine ground wire of answering the call.The clock frequency control end OSI of speech chip B is connected in series a resistance R 3, is used for adjusting newspaper speech frequency and speed.

The design principle of these voice Charging telephone and the course of work:

1) for realizing transfer of data, on charging integrated chip A original program basis, the amount of money part when number data of keypad input and telephone relation are finished on the display screen and the coding rule coding of speech chip B agreement, the VOLO end-grain cutting of charging integrated chip A is changed to data output end, and will encodes and deliver to the address end OATA of speech chip B by this end.

2) speech chip B receives code signal, by decoding with the agreement coding rule of charging integrated chip A, speech chip B decodes successfully then by BUSY end output low level, be sent to the hands-free received power amplifier power supply of phone switching tube and open amplifier power supply, and with decoded result SPK end output voice signal by speech chip B after digital-to-analogue conversion, the power amplifier that is sent to the hands-free reception of phone amplifies.

When 3) off-hook is made a phone call, charging integrated chip A will export Outgoing Number, deliver to the OATA end data pin of speech chip B by the VOLO end of charging integrated chip A, by the SPK end of speech chip B voice output is delivered to hands-free reception amplifying circuit and send the newspaper sound, its operation principle is the same with above-mentioned subscription rate process.

Claims

1, a kind of voice charging phone, comprise: support and microphone, be provided with in the support and contain caller identification, charging, liquid and show the telephone circuit that drives, sends out number in the charging integrated chip A of one, it is characterized in that: the Data Control end-grain cutting of the charging integrated chip A of telephone circuit is changed to data output end, and connects a speech chip B with serial line interface transmission data mode; The answer the call amplifier power supply control end of circuit of the power end of the speech chip B power supply of answering the call, the speech output end of the speech chip B power amplifier input of answering the call, the amplifier power supply control end of speech chip B.

2, voice charging phone according to claim 1 is characterized in that: the clock frequency control end OSI serial connection one of speech chip B can be adjusted the resistance R 3 of newspaper speech frequency and speed.
