The present invention relates to a method for selecting a ring tone of a telephone and a device thereof. In particular, when a sender selects a desired ring tone by using a predetermined selection button after the dialing of the telephone number is completed, the ring tone selected by the receiver's telephone is selected. It can be output as a signal so that you can easily make a call with a specific person, and when you use the fax using a single phone, you can select the ring tone of the phone so that you can answer the call according to the bellso or connect the CO line to the fax. A method and apparatus therefor.

In the conventional telephone, most of them are configured to output one ring sound signal.

Therefore, the telephone dial tone device, which has been developed as a means to solve this problem and has been filed in Korean Utility Model No. 91-15807, has a selection switch installed at the input of the IC ring generator to selectively ring several ring sound signals. It is.

However, such a configuration requires the user to switch the ring tone selector switch installed in his or her telephone directly to a predetermined ring tone signal side so that the ring of his phone rings with the sound signal.

That is, because the receiver himself is configured to select the ringtone signal to ring on his or her phone, the sender's intention cannot be accurately communicated, so that many people do not let others know who they are through a common phone. In order to make an accurate call with a specific person, the user rings a certain number of rings and then hangs up, recognizing that the promised person is his or her caller. There is a situation.

By the way, once the phone rings, it is customary to answer the phone, and after a few rings, the caller will be offended because the other party hangs up already or at the moment the call is received. Rather, there was a problem that the use of unnecessary telephone lines and the increase of telephone bills.

In addition, when using a single phone in parallel with a predetermined fax, most users leave the fax in manual reception mode and use it as a regular telephone. When a call comes in, the telephone is intended for a general call. Not only do you not know whether you want to send the data, but not only hesitate to receive the call, but only after the other party calls and hears that you want to send a manuscript through the fax. The conversion to the facsimile side, such as the need to use the telephone line unnecessarily, as well as the increase in the telephone bill there was a problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for selecting a ring tone of a telephone and a device in which a sender can change a ring tone of a counterpart to an arbitrary sound signal so that a call can be easily made with a specific person.

Another object of the present invention is to allow a receiver to distinguish between a regular phone call and a facsimile call through different phone rings when using a single phone in parallel as a facsimile phone to prevent unnecessary phone line occupancy and increase in telephone charges in advance. The present invention provides a method and a device for selecting a ringtone for a telephone, which can prevent and improve reliability of a product.

The above object is the first ring in series with a hook switch, an input time detector for a predetermined ring signal in a conventional telephone, several ring sound generators for generating different ring sound signals, a driver for selectively driving them, and a hook switch. After the signal is generated, the relay is switched off and on automatically regardless of the hook switch for a certain period of time, and a predetermined program is input by entering a predetermined program in the microcomputer. When the select button is operated, the first ring signal is output only for the time corresponding to the bell sound signal selected above, and then the telephone line is disconnected and reconnected to redial the ring signal. This can be achieved by having the receiver's phone ring with the desired ring tone signal.

In the ring sound selection method of the present invention, as shown in (a) and (b) of FIG. 2, when the hump switch HS is turned 'on' and dialing for a predetermined telephone number is performed, a predetermined ring sound is subsequently performed. If the bell sound selection key signal is not detected and the bell sound selection key signal is not input, a dial signal is generated through the trunk line to output a ring signal at the switchboard. Recognizes the telephone number dialed in and generates a dial signal through the trunk line for a predetermined time (t1-tn) according to the ring tone selected above, and outputs a ring signal at the switchboard, respectively, and then for each predetermined time (t1-tn). ) Is elapsed, the contact switch (S) of the relay (RL) 'off' for a certain period of time to cut off the trunk line and 'on' again, the bell consisting of the process of redialing the previously stored phone number Acoustic Select and transmit routines; If the ring signal transmitted through the trunk line L is input for more than a predetermined time (t1-tn) while the hook switch (HS) is 'off', and is input for more than a predetermined time (t1-tn), the previously selected If the bell sound continues to be generated by the sound signal and is input within a predetermined time (t1-tn), the bell time is detected and the bell sound is switched through the bell sound switching unit 16 when the output of the bell sound signal is completed. After the trunk line is connected to the bell sound driver 17a-17n corresponding to the sound selection signal, and the ring signal is input again, the ring sound, melody and bird sound generator 18a-is transmitted through the selected bell sound driver 17a-17n. 18n) to selectively drive the ring switch (HS) until the hook switch (HS) is 'on' or the sender 'turns off' his hook switch (HS). Ring sound output routine It is characterized by.

Referring to the effects of the present invention as follows.

First, the microcomputer 11 is always in a standby state because a constant DC voltage is always applied from the constant voltage unit 12 that converts an output voltage of a predetermined battery or an adapter into a constant voltage, and the relay RL is in a non-state state. Since it is in the driving state, the movable terminal C of the contact switch S thereof remains connected to the fixed terminal B, so that one side of the hook switch HS and the switching unit 6 are normally connected. do.

At this time, when the user makes a call to a predetermined receiver or picks up a telephone receiver and receiver 4 or 5 to transmit a predetermined document through a fax, the hook switch HS is 'on' and the trunk line L It is connected to the switching part 6 via the contact switch S of this hook switch HS and the relay RL.

In this state, when the user presses a predetermined telephone number through the key input unit 2 of the telephone, the dialing unit 3 receives the predetermined number and outputs a predetermined pulse corresponding to each of the switching unit 6 and It is transmitted to the exchange through the CO line, in which the microcomputer 11 continues the predetermined ring tone selection key (for example, after dialing is completed in order for the user to randomly change the ring tone signal according to the ring tone generated from the other party's phone). Assuming that # 2 is selected to select the melody sound, a bell sound selection key detector 13 detects whether a signal is input.

If only the dialing of the predetermined telephone number is executed and the ring tone selection key is not pressed, the dial signal is generated through the trunk line as in the existing telephone, and the ring signal is output until the other party answers the call. To be done.

However, if the ring tone selection key signal is inputted after dialing the predetermined telephone number in the above, the telephone number recognized by the telephone number recognition and redialing unit 3 is stored and stored in the telephone number at the switchboard. After the ring signal is output to the corresponding telephone only for a predetermined time t1-tn according to the ring sound selected above, the relay line is driven to block the trunk line.

That is, the ring signal generated from the switchboard is detected through the ring signal detection unit 8, and a predetermined time according to the ring sound selected by the user (for example, 1 second when selecting a ring tone, 2 seconds when selecting a melody sound, and 3 when selecting a bird sound). Second), the driving terminal C of the contact switch S thereof is connected to the fixed terminal A by driving the relay RL, even if the hook switch HS is in the 'ON' state. As the trunk line is blocked by the contact switch S of the relay RL, the ring signal transmitted from the switchboard to the receiver's telephone is transmitted only for the predetermined time.

In this case, the shorter the predetermined time (t1-tn) is better, which means that if the ringer gets longer, the receiver lifts the receiver and receiver (4, 5) before switching the receiver to the intended ringtone. Not only is there a concern that the conversation and the facsimile conversion will be unsuccessful, but it also becomes a factor that unnecessarily occupies the telephone line.

In this state, when a certain time elapses, the microcomputer 11 cuts off the driving of the relay RL. Therefore, the movable terminal C of the contact switch S is connected to the fixed terminal B which is normally closed. The microcomputer 11 is connected to the internal circuit of the telephone. At this time, the microcomputer 11 outputs an output signal for the previously stored telephone number to the dialing unit 3 through the telephone number recognition unit 14 so that the user inputs the key input unit. Even if the dialing is not performed again through (2), the dialing unit 3 redials the ringing signal again to the desired receiver at the switchboard.

On the other hand, in the microcomputer of the other party's phone, if a predetermined ring signal is transmitted through the trunk line L while the hook switch HS is 'off', the ring signal detection unit 8 recognizes the ring signal and then rings the ring signal. The ring signal input time detector 15 continuously detects whether or not the transmission time of the signal is greater than or equal to a predetermined time t1-tn.

At this time, if the ring signal is input for more than a predetermined time (t1-tn) from the time when the ring signal is first detected, it is recognized that the ring sound selection is not made and the previously selected sound signal (for example, a ringtone) as in the existing telephone is selected. Ring sound is continuously generated, and if the ring signal input time detector 15 detects the input time of the ring signal, and the predetermined time (t1-tn), the ring signal input time (for example, 2 seconds) After detecting and recognizing t2), the bell sound switch is connected to the bell sound driver 17a-17n corresponding to each ring sound selection signal through the bell sound switching unit 16 at the time when the output of the bell sound signal is completed. Let it be.

Therefore, the ring signal transmitted from the switchboard is input to the corresponding generation unit through the ring sound driving unit selected by the ring sound switching unit 16 among several bell driving units 17a-17n. If # 2 is selected to output the melody sound, the melody sound is output from the speaker SP because the melody generating unit 18b is driven through the bell sound driving unit 17b in the bell sound switching unit 16.

That is, the microcomputer 11 in the receiver telephone detects whether the ring signal is input again through the ring signal detection unit 8, and when the ring signal is input again, the bell sound driver selected from several ring sound drivers 17a-17n is selected. By selectively driving the ringtone, melody and bird sound generating unit (18a-18n) is to call the receiver with the sound signal.

At this time, the ring tone for calling the receiver is that the receiver picks up the handset (4, 5) and recognizes that the hook switch (HS) of the receiver phone is 'on' or the receiver does not answer the call. By lowering it, it continues until the hook switch HS of the sender's telephone is 'off'.

In addition, the microcomputer 11 maintains the control state of the ring sound switching unit 16 until the present state of the ring sound selection signal of the sender next input.

Therefore, when the caller dials his / her own phone number to make an appointment with a specific person without informing others who he or she is through a telephone that is commonly used by many people, a random sound is heard. By operating a selection key that can be changed to a signal, the telephone ring of the receiver side is output as the ring tone signal selected above, so that a call with a specific person can be easily made.

In addition, when used in parallel with a predetermined facsimile using a single phone, the receiver wants to make a general call through different phone rings (for example, a ringtone for a regular phone and a bird sound for a fax). You can easily recognize that you want to send the original and know exactly whether you want to pick up the handset (4, 5) or operate the receiving button of the fax machine. Can be.

At this time, the number of the bell sound generating unit can be arbitrarily changed, so that any other bell sound (for example, water sound, a specific animal sound, a voice signal using a voice recognition integrated circuit, etc.) can be selected by the sender.

As described above, according to the present invention, when the calling party dials the telephone number, the telephone ringer (i.e., ringing tone) of the called party is arbitrarily changed, and the ringing tone is selected by the sound signal selected by the telephone of the called party. Not only can the call with a specific person be made accurately, but also when the fax is used in parallel through a single phone, the receiver can easily distinguish between normal phone calls or facsimile calls by different ring tone signals. It is a useful invention that can be easily performed to prevent unnecessary occupying the telephone line or to increase the telephone bill in advance to improve the reliability of the product.
