Description

The IP phone dialer

The utility model relates to a kind of number input unit that is mainly used in telephone communication.

Present various IP phonecard is come out one after another, and the use of these cards has brought convenience also to save telephone expenses to toll message.But need import a lot of information desk number and card number etc. during owing to these IP phonecards of use, not only time-consuming but also make mistakes easily when therefore using, particularly more sense inconvenience concerning the relatively poor people of those memory is while often need to see that the number on the phonecard Enters Number during use.

The purpose of this utility model is to provide a kind of IP phone dialer that is connected on the telephone line, and it can be set the number of the required dial-out of IP phone and long term storage in advance, the number that sets can be transferred to according to the order of sequence the IP phonecard connection process of finishing when needing.

This device is provided with box body, dialing keyboard, dial-up circuit, audio amplifier circuit, DC power supply and printed circuit board (PCB), dialing keyboard is located on the box body, dial-up circuit and audio amplifier circuit are welded on the printed circuit board (PCB), the output termination dial-up circuit of dialing keyboard, the output termination audio amplifier circuit of dial-up circuit, the external telephone wire both positive and negative polarity of the output of audio amplifier circuit.

Said dial-up circuit can be become by the integrated circuit bank of existing special-purpose dialing, also can be made up of the single-chip microcomputer that has the dual-tone dialing circuit, or add that by single-chip microcomputer the double-tone living integrated circuit that takes place frequently forms.Audio amplifier circuit can be made up of triode or audio frequency amplification circuit.DC power supply adopts battery.

When using this dialer, need the M of desired number by dialing keyboard ₁, M ₂, M ₃Or the SAVE key deposits in the memory, and for example the number that need dial certain Jitong's IP phonecard is: 17920 (information desk number)+1 (or 2) (Chinese and English is selected)+52645736# (account number)+1234# (4 passwords).Then can deposit M in 17920 ₁, 1+Pause (time-out)+52645736# (account number) deposits M in ₂, 1234# (password) deposits M in ₃When using, press earlier M ₁Then transfer to 17920 automatically; Press M after hearing prompting (selecting Chinese and English) ₂, then earlier " 1 " to be transferred to through Pause and suspended a moment, prompting input this moment account number is then transferred to 52645736# (account number) automatically; Behind prompting input password, press M ₃, then transfer to 1234# automatically; Connecting behind the circuit (prompting input the other side's telephone number) can be from phone or this dialing keyboard input the other side's telephone number, and finishes conversation.As seen this device can greatly make things convenient for the use of IP phonecard.When not having dialing owing to this dialer in addition, audio amplifier circuit ends, and therefore at ordinary times telephone line is had no effect.This dialer can be carried, as long as there is the place of telephone wire all can use, and sets number and can not lose.

This shows that this dialer can be Entered Number and password voluntarily by the user, then once can finish whole operations, unique number that has only the other side that needs input.In addition, this dialer is in light weight, also can be designed to the key chain pattern, and is easy to carry; Also can be designed to various animal-shaped and colors, increase its interest.Also can adopt the dialing integrated circuit or the single-chip microcomputer of band LCD interface, be designed to dialing mechanism with liquid crystal display.This device also can be used for the occasion that other need Enter Number except that being used for circuit communication.

Fig. 1 is a theory diagram of the present utility model.

Fig. 2 adopts the circuit theory diagrams of private dialup integrated circuit for the utility model.

The dial-up circuit schematic diagram of Fig. 3 for adopting DTMF generator single-chip microcomputer to form.

Fig. 4 produces the dial-up circuit schematic diagram that circuit is formed frequently for adopting single-chip microcomputer and double-tone.

Embodiment 1: see Fig. 1, and 2, this device is provided with box body, dialing keyboard J, dial-up circuit 1, audio amplifier circuit 2, DC power supply 3 and printed circuit board (PCB), and dialing keyboard J is located on the box body.The printed circuit board (PCB) that is welded with dial-up circuit 1 and audio amplifier circuit 2 is fixed in the box body.The output line of dialing keyboard is connected to 2～6 and 20～23 pin of dial-up circuit, and dial-up circuit adopts the private dialup integrated circuit (IC) ₁(HT9315D), DTMF termination triode (A42) audio amplifier circuit, the positive and negative end L of the external telephone line of the output of audio amplifier circuit ₁(+) and L ₂(-).Dialing keyboard has 3 singly-bound storage M ₁, M ₂, M ₃, 1 SAVE key and 1 redial key.

Embodiment 2: as Fig. 3, dial-up circuit is the single-chip microcomputer U of band DTMF generator ₁

Embodiment 3: as Fig. 4, dial-up circuit is by single-chip microcomputer U ₂Frequently produce IC circuit with double-tone ₂Form.
