Description

How to adjust the ring volume on your phone

The present invention relates to a ring volume adjusting method of a telephone, and more particularly, to a ring volume adjusting method of adjusting a ring volume according to an up / down key input in a telephone.

In general, telephones have been informed that a telephone call has been made to a user of the telephone by generating a ring in response to an incoming call from the outside. At this time, the ring volume was to allow the user to adjust the ring volume using the volume control volume lever installed in the phone. Accordingly, the phone for adjusting the ring volume using the volume control volume lever has a problem in that the volume of the phone is increased because a space for installing the volume control volume lever must be secured separately.

Therefore, an object of the present invention is to provide a ring volume control method for adjusting the ring volume using the volume up / down keys.

According to the present invention for achieving the above object, the volume level of the ring volume is increased or decreased each time the volume up key or the volume down key is pressed to adjust the size of the ring volume, and use the indication of the adjusted volume level level. It is characterized by the display.

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

1 is a block diagram of a ring volume control device according to an embodiment of the present invention.

The tone ringer rejection 10 uses a general-purpose tone ringer IC, and generates ringing sound for notifying a telephone call in response to a ring signal being input from a telephone line. The ring detection unit 12 is connected to the telephone line and detects a ring signal input from the telephone line and provides it to the CPU 16. The hook detection unit 14 detects the hook on / off state of the telephone set from the operating state of the hook switch and provides it to the CPU 16. The key input unit 24 generates a volume up and down key signal and various function key and dial key signals and applies them to the CPU 16. The volume up key and the volume down key of the key input unit 24 may be configured by combining a ten key provided in the telephone or may include a separate up down key. The CPU 16 outputs a control signal for gradually increasing the volume of the ring volume according to the up / down key signal input from the key input unit 24 to the control terminals A, B, and C of the MUX 18, and adjusts the volume level. Control to display status. The display unit 26 displays the level value of the sound volume by the control symbol of the CPU 16. The MUX 18 selects the level of the ringing tone output from the tone ringer rejection unit 10 according to the volume level control signal output from the CPU 16 and outputs it to the amplifier 20. The amplifying unit 20 amplifies the ring tone level signal selected and output from the MUX 18 and transmits the predetermined amplification signal to the speaker 22.

1 and 3, the operation of the preferred embodiment of the present invention will be described in detail.

In the idle state of step 101, the CPU 16 checks whether the volume up key is pressed from the key input unit 24, and proceeds to step 103 when the volume up key is pressed. In step 103, the CPU 16 adjusts the ring volume level by one step and proceeds to step 106. However, if the volume up key is not pressed in step 102, the process proceeds to step 104. The CPU 16 checks whether the volume down key is pressed from the key input unit 24. If the volume down key is pressed, the process proceeds to step 105. In step 105, the CPU 16 decreases the level value of the ring volume by one step and proceeds to step 106. In step 106, the CPU 16 displays the level value of the ring volume on the display unit 26 as shown in FIG. Then, in step 107, the CPU 16 stores the level value of the adjusted ring volume in the internal memory and returns to step 102. When the ring signal arrives from the telephone line after the level value of the ring volume is adjusted, the tone ringer rejection 10 generates and outputs a ring tone. At this time, when a ring signal is detected from the ring detector 12, the CPU 16 controls the MUX 18 to a level value of the ring volume stored in the internal memory to select and output the level of the ring tone signal generated from the tone ringer 10. The MUX 18 selects and outputs one of ring ring signals input through the resistors R0-R7 by the CPU 16. Although eight resistors have been described as an example, eight or more resistors may be provided to further refine the adjustment of the ring volume. In this way, after adjusting the level value of the ring volume in the idle state, when the ring signal is detected from the ring detector 12, the ringer sounds at the adjusted level of the ring volume. In addition, if the volume up / down key of the key input unit 24 is pressed while the ringing tone is sounded, the ring volume may be raised by one step or higher whenever the volume up / down key is pressed. In addition, since the ring volume control level state is displayed on the display unit 26, it is easy to recognize how much the volume level state of the current ring volume is at the maximum level.

As described above, the present invention provides a separate volume control lever by adjusting the ring volume level to a larger or smaller level and displaying the adjusted ring volume level each time the volume up key or the volume down key is pressed. There is no need to secure space, which reduces the volume of the phone.
