Abstract

A method for generating a ring sound of a telephone using a reservation music sound is disclosed. First, a ring signal is detected. In case of detecting the ring signal, the reservation music sound circuit is operated to generate the reservation music sound. And then, the state of a hook of the telephone is monitored. In case the hook is off, the reservation music sound is not provided, and then a telephone loop is established. In case that, a reservation music button signal is inputted, the reservation music sound circuit is also operated.

The present invention relates to a ringing sound of a telephone, and more particularly, a ringing sound generating method of a telephone using held music which allows a caller to replace a ringing sound, which is a means for recognizing that a call is coming, to a caller. It is about.

In general, ring sound in a typical typical telephone is a means of recognizing that a call has been made by generating an intermittent sound to a user when a ring signal generated from an exchange is input to a microprocessor. It was provided separately and selectively generated based on a control signal from a microprocessor.

On the other hand, the hold music in the phone is an additional service function of the phone that allows the caller to listen to music while waiting for the caller to send the stored music stored in advance and stored in the case of waiting for a while for the caller to wait.

However, the conventional typical telephone having the function as described above has a problem in that manufacturing costs are increased by providing circuits for holding music and circuits for ring sound generation, respectively.

Accordingly, the present invention has been made in order to solve the problems of the prior art as described above, the object of the present invention is to provide a ring sound generating method of the telephone using the suspended music to be generated by replacing the ring sound with the holding music. have.

In order to achieve the above object, the present invention, in the method for generating a pending music to be sent to the caller using the pending music button to replace the ring sound, the process of detecting the input of the ring signal through the trunk line And, if the ring sound is detected, the process of holding music circuit to operate the hold music circuit to generate a hold music through the speaker to recognize that the call is received to the user, and if the hook state is detected by the hook off state, the holding music is stopped and the telephone loop A ring of the telephone using the held music, comprising: forming a step; and detecting whether the held music button is input during a call based on the step; operating the held music circuit if the input is made; Provides a sound generating method.

Other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the drawings referred to by those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a typical telephone employed in accordance with the present invention. As shown in the figure, the telephone employed in the present invention includes a ring detection unit 10, a microprocessor 20, a holding music circuit unit 30, a hook detection unit 40, a key input unit 50, a voice amplifier unit ( 60, a telephone call circuit unit 70.

In the figure, the ring detection unit 10 detects a ring signal, which is a means for recognizing a telephone call to a user, which is transmitted from an exchange through a trunk line preference, and transmits the detection signal to the microprocessor 20.

In addition, the microprocessor 20 controls the overall operation of the phone, and in particular, when a ring signal is input from the ring detection unit 10, the holding music circuit unit 30 is driven to generate the holding music through a speaker (not shown). Instead, if the input is detected and input the hold music button input from the key input unit 50, the holding music circuit unit 30 is driven to the other party through the telephone loop configured by the phone call circuit unit 70 through the voice amplifier 60; Pending music to you.

In addition, the reserved music circuit unit 30 memorizes the reserved music in advance and sends it out based on a control signal from the microprocessor 20 to prevent the boredom while the other party waits for a while.

Meanwhile, the hook detector 40 detects a hook on / off state and transmits the detection signal to the microprocessor 20, and the key input unit 50 is an input means for performing a desired operation of the telephone. A number is inputted with a special button such as a button and a hold music button for transmitting the hold music.

Then, the voice amplifier 60 amplifies the music stored in the reserved music circuit section 30 and transfers it to the telephone call circuit section 70.

Lastly, the telephone call circuit section 70 is a circuit section for forming a telephone loop for the impedance matching and the call of the trunk line and the telephone, and selectively turns on / off the telephone loop based on a control signal from the microprocessor 20. Let's do it.

Next, with reference to the flowcharts of FIGS. 1 and 2 attached to the ring sound generation process of the telephone using the suspended music according to the preferred embodiment of the present invention in the telephone including the above-described configuration.

First, it is detected through the ring detector 10 whether there is an input of a ring signal transmitted from the exchange via the trunk line (step 200). At this time, when the input of the ring signal is detected, the holding music circuit unit 30 is driven to generate the holding music stored in the holding music circuit unit 30 as ring sound (step 202) to the outside through a speaker (not shown). A hold music is generated (step 204) to inform the user that a call has been made.

Next, the hook detection unit 40 detects whether the user is hooked off (step 206), and stops the held music that has been continuously generated when the hook is turned off by controlling the held music circuit unit 30 (208).

Then, the telephone call circuit unit 70 is controlled to turn on the telephone loop to form a telephone loop (step 210) to allow a call with the other party (step 212).

On the other hand, according to the above process, when the user enters the hold music button through the key input unit 50 to temporarily wait for the caller in the call state, the microprocessor 20 detects this (step 214), and the hold music circuit unit. (30) is driven again (step 216), the amplified music is read from the held music circuit unit 30 through the voice amplifier unit 60 and amplified and transferred to the telephone call circuit unit 70, thereby sending the held music to the other party ( Step 218) Relieves boredom while waiting for a while.

As described above, according to the present invention, it is possible to reduce the cost by replacing the ring sound from the ring sound generating element of the conventional typical phone with the pending music, and by replacing the ring sound with the soft music instead of the hard crackdown sound to the user. It can provide a soft ring sound.
