The utility model discloses a phone automatic dialer, which is positioned on a connection lead (3) of a phone control board (1) and a phone handle (2), the phone control board (1) is positioned is electrically connected with a microphone (4) in the phone handle (2) by an electric wire (5), an output end of the phone automatic dialer is connected with the electric wire (5), the utility model simplifies the circuit structure of the phone automatic dialer and has a low cost, audio frequencies which are produced by the phone automatic dialer directly inputs the phone control board by the electric wire, the utility model has a low error rate, an simple, convenient and easy operation, whose incorrect operated numbers also are not easy to be lost, whose stored numbers will not be lost even if the dialer rus down of the battery power or accidentally powers off because the utility model can be continuously used only by connecting with the power source again.

Description

A kind of telephone automatic dialing device

1, technical field:

The utility model relates to a kind of telephone set annex, relates in particular to a kind of telephone automatic dialing device.

2, background technology:

The technical scheme that existing telephone automatic dialing device adopts has two kinds:

1) manufactures an independently autodialer that separates fully with telephone set, its behaviour in service as shown in Figure 1, utilize dialer A to go up the audio signal of generation by the loudspeaker B output that carries, then with the microphone E on the handle D of loudspeaker B aligning telephone set, and compress, the audio signal of loudspeaker B output by microphone E be sent to telephone set main frame F, be sent to telecommunication operators by main frame F by telephone wire again.The shortcoming of this scheme is: dialer A goes up the microphone E on the handle D that loudspeaker B must aim at telephone set, and compress, just can dial then, operate cumbersome, if press tightly or press to such an extent that too tightly all can cause dialing unsuccessful, in the process of dialing, hand vibrations a little all might cause the dialing failure.

2) this autodialer is connected on the telephone wire between telephone set and the telecommunication operators, so this autodialer must have the networking card that telecommunication administration is provided, otherwise can not use, the signal that this autodialer must be discerned and handle between telecommunication operators and the telephone set transmits, and function must be perfect, therefore, this autodialer circuit structure is very complicated, and volume is bigger, and cost is higher, and the error rate is higher when identification and detection signal.

In addition, there is a common shortcoming in above-mentioned two kinds of autodialers: existing dialer all is to adopt the mode that carries keyboard, and erasable device and dialer are to cause one, therefore misoperation and cause losing of telephone number easily.And the telephone number of storage generally is that in case power down, number will be lost by inner IC preservation number.

3, summary of the invention:

The purpose of this utility model provides a kind of telephone automatic dialing device, being connected on the electric wire of microphone inside it directly is connected main station and is positioned at telephone handle, the audio signal that the telephone automatic dialing device produces is directly inputted to main station by this electric wire, send by main station again, so, can simplify the circuit structure of telephone automatic dialing device, the error rate is lower, simple to operation, cost is lower.

The utility model is achieved by the following technical solution: it is positioned at being connected on the lead of main station and telephone handle, and main station is electrically connected by electric wire with the microphone that is positioned at the telephone handle the inside, and its output is connected on this electric wire.

The utility model comprises digital control module, memory, button and D/A change-over circuit, memory, button link to each other with digital control module, the output of digital control module connects D/A change-over circuit input, and the output of D/A change-over circuit is connected on the lead.

Above-mentioned described memory is an erasable programmable read only memory.

Above-mentioned described memory also is connected with erasable device by dismountable cushion.

Above-mentioned described digital control module can be a single-chip microcomputer.

Above-mentioned described erasable programmable read only memory can be EEPROM or FLASHROM.

The utility model compared with prior art has following advantage: 1) it is connected on the electric wire of main station and the microphone that is positioned at telephone handle the inside by the output with the telephone automatic dialing device, the audio signal that the telephone automatic dialing device produces is directly inputted to main station by this electric wire, send by main station again, so, can simplify the circuit structure of telephone automatic dialing device, cost is lower; 2) audio signal of telephone automatic dialing device generation is directly inputted to main station by this electric wire, and the error rate is lower, and is simple to operation easy; 3) the utility model adopts the mode that erasable device separates with dialer, after the dialer number is finished writing, can remove the cushion that memory is connected with erasable device, realize separating, revising the dialer number must could change with the erasable device that our company provides, and causes number to be lost with regard to having avoided misoperation like this.Because what the utility model adopted is that memory is an erasable programmable read only memory, for example EEPROM or FLASHROM, even the dialer battery electric quantity exhausts or unexpected power down, the number of storage can not lost yet, and just can continue to use as long as connect with the mains again.

5, embodiment:

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model is positioned at being connected on the lead (3) of main station (1) and telephone handle (2), main station (1) is electrically connected by electric wire (5) with the microphone (4) that is positioned at telephone handle (2) the inside, and output of the present utility model is connected on the electric wire (5).The utility model comprises digital control module (6), memory (7), button (8) and D/A change-over circuit (9), memory (7), button (8) link to each other with digital control module (6), the output of digital control module (6) connects D/A change-over circuit (9) input, and the output of D/A change-over circuit (9) is connected on the lead (5).Memory (7) is an erasable programmable read only memory.Memory (7) also is connected with erasable device (11) by dismountable cushion (10).Digital control module (6) can be a single-chip microcomputer, and erasable read-only memory can be EEPROM or FLASHROM.

The connected mode of erasable device of EEPROM (11) and autodialer: spare interface on the circuit board of autodialer (12), on the erasable device of EEPROM (11), pick out four spring needles, as long as autodialer is placed on the erasable device (11), cooperate corresponding computer software, just can carry out erasable autodialer.

The main purpose of the utility model design is the number for group IP phone service provider, such as: the number of the IP phone of China Telecom is 17909, and we can be input to IP dialer the inside to this telephone number.Only need press the button of autodialer before will making a long-distance call later, these 5 numbers will be exported successively at every turn.

This design can also be used for other field, as is used for dialling 200 phones, only need be with 200, and card number, password, input autodialers such as the time of pause just can reach and utilize 200 purposes of making a phone call.Also can be used for dialling emergency numbers or the like.
