In order to achieve the above object, a telephone number automatic dialing device according to a preferred embodiment of the present invention includes a key input unit having a plurality of numeric keys and a plurality of mode designation buttons; A memory for storing a telephone number input from the key input unit; A display unit for displaying a phone number keyed in by the key input unit and displaying a phone number stored in the memory; A controller for controlling a plurality of modes input from the key input unit and generating a natural frequency signal corresponding to the telephone number; And a signal output unit for transmitting the natural frequency signal generated by the controller to a telephone.

Automatic telephone number dialing method according to an embodiment of the present invention, the input step of inputting a telephone number using a key input unit; A storage step of displaying the input telephone number and storing it in a memory; A search step of searching for a desired number of calls from the stored telephone numbers; A signal generation step of generating a natural frequency signal corresponding to the retrieved number; And a transmitting step of transmitting the generated signal to a telephone.

Hereinafter, an apparatus and method for automatically dialing a telephone number according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a configuration diagram of an automatic phone numbering device according to an embodiment of the present invention, a plurality of numeric keys (0 to 9), special characters (#, *) buttons, a storage button for designating and releasing a phone number storage mode; And a key input unit 10 including a completion button, a search button for designating a phone number search mode, a delete button for designating a phone number deletion mode, a call button for designating a phone call mode, and the like; A memory 12 for storing a plurality of telephone numbers keyed in the key input unit 10 as data; A display unit 14 for displaying a telephone number being input under the telephone number storage mode and displaying a telephone number searchable under the telephone number search mode; Signal output unit for transmitting the natural frequency signal (DTMF signal) corresponding to any one of the plurality of telephone numbers in the memory 12 to the telephone 18 via a data line (DL, like a kind of dedicated line) (16); And a controller 20 for controlling a phone number storage, retrieval, deletion, and automatic dialing operation after designating a corresponding mode based on a key input signal from the key input unit 10. The components of the automatic telephone numbering control apparatus of the embodiment of the present invention described above are all installed in the audio device.

The display unit 14 is installed at a predetermined portion of the front panel of the corresponding audio device.

The key input unit 10 is installed on the front panel of the audio device, and is also installed in a remote controller (remote control) for remotely controlling the audio device.

When the signal output unit 16 provides arbitrary telephone number information from the control unit 20, the signal output unit 16 generates a corresponding frequency signal DTMF signal corresponding to the telephone line 18 through the data line DL. do.

When the predetermined frequency signal (DTMF signal) is input from the signal output unit 16, the telephone 18 performs automatic dialing based on the specific frequency signal (that is, the signal representing the called party's telephone number). do. Assuming that the telephone 18 is a general wired telephone or a wired / wireless telephone, when a natural frequency signal (DTMF signal) is input from the signal output unit 16, the telephone 18 is in an off-hook state. After auto switching, auto dialing is performed based on the input natural frequency signal.

The control unit 20 is composed of a microprocessor.

Next, the operation of the automatic telephone numbering device according to the embodiment of the present invention will be described with reference to the flowchart of FIG. 2.

The user presses the save button of the key input unit 10 when there is a phone number to be stored. As a corresponding storage button operation signal is applied to the control unit 20, the control unit 20 switches to the phone number storage mode and receives a number for a phone number keyed in by the key input unit 10 (step) S10).

When the user completes input of any one phone number, the user presses a completion button, and a corresponding completion button operation signal is applied to the control unit 20 so that the control unit 20 wants to store the currently input phone number. A message for inputting the memory address is displayed on the display unit 14. In this case, the controller 20 may display information on the memory addresses that can be input (that is, empty) on the display unit 14.

Accordingly, when a user inputs or selects a memory address by operating a numeric key of the key input unit 10, a corresponding memory address input (or selection) signal is applied to the control unit 20, and the control unit 20 Saves the currently input telephone number to the corresponding memory address (step S12).

After that, if there is a phone number to be searched for, the user presses a search button after keying in the search desired phone number. The control unit 20 then switches to the phone number search mode and searches whether the input search desired phone number is in the memory 12.

On the other hand, if the user does not want to make a phone call but has a phone number to delete ("No" in step S14 and "Yes" in step S16), the user presses the delete button after keying in the phone number to delete. The controller 20 searches for and deletes the corresponding phone number stored in the memory 12. In addition, even when the user presses a delete button after finding a phone number to delete using the search button, the controller 20 deletes the corresponding phone number stored in the memory 12 (steps S18 and S20).

If the user wants to make a telephone call ("Yes" in step S14), the user presses the search button of the key input unit 10. Accordingly, a corresponding search button operation signal is applied to the control unit 20, and the control unit 20 switches to the phone number search mode and sequentially displays the phone number on the display unit 14. FIG. The user looks up the telephone number of the other party (called party) who wants to make a telephone call while looking at the telephone number displayed on the display unit 14 (step S22).

When the phone number of the other party who wants to make a phone call is found ("Yes" in step S24), the user presses the call button of the key input unit 10. Accordingly, the corresponding call button operation signal is applied to the control unit 20, and the control unit 20 switches the telephone call mode and then outputs the phone number information at the time the call button is pressed. To (16). The signal output section 16 generates a natural frequency signal DTMF signal corresponding to the input telephone number information and transmits it to the telephone 18 via the data line DL (dedicated line). Accordingly, the telephone 18 performs automatic dialing based on the input natural frequency signal (step S26).

Meanwhile, in the above-described embodiment of the present invention, it has been described that the audio device can store, retrieve, delete, and automatically dial a phone number. However, a simple electronic calculator function can be added by using a numeric key and a menu key. .

As described in detail above, according to the present invention, by storing, retrieving, deleting, and automatically dialing a phone number in an audio device, it is possible to increase the utility of the product and to improve product satisfaction and to create a high value of the product.

On the other hand, the present invention is not limited only to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, the technical idea to which such modifications and variations are also applied to the claims Must see
