AUTO ADJUSTMENT SYSTEM OF AUDIO SIGNAL WITH PHONE BELL SIGNAL AND THE METHOD THEREOF}

The present invention relates to an apparatus and method for automatically adjusting the size of an audio signal according to a telephone signal. More particularly, when a telephone signal is input through a modem during the reproduction of an audio signal using a computer system, the computer system automatically sizes the audio signal. Reduce or mute the audio signal, and when the telephone call is finished or the auto answer mode is activated, the audio signal size is automatically adjusted according to the telephone signal for the user's convenience. A control device and method are provided.

1 is a schematic block diagram of a computer.

A signal related to audio control input from an input unit 10 such as a keyboard or a mouse or a telephone signal input through a modem 20 is input to an input / output control hub 30 and a memory control hub 40, and the memory Modem driver 50 for interrupting the telephone signal output from the control hub 40 to the operating system (OS) 70, and the telephone call control unit to enable a telephone call when the telephone signal is interrupted from the modem driver 50 ( An OS 70 for performing the operation 80, an audio driver 60 for interrupting the audio signal output from the memory control hub 40 to the OS 70, and an audio signal output from the audio driver 60. The audio codec 90 to encoder or decoder, the amplifier 100 to amplify the signal output from the audio codec 90 to the speaker 120, and the user directly adjusts the volume of the audio signal It consists of a volume key 110 for controlling the amplification degree of the amplifier 100.

The process of inputting a telephone signal and reproducing the size of the audio signal during the reproduction of the audio signal according to the related art as described above will be described.

When a computer user inputs a telephone signal through the modem 20 of the computer while playing the audio signal, the telephone signal is input to the modem driver 50 through the input / output control hub 30 and the memory control hub 40. When the telephone signal is interrupted from the modem driver 50, the OS 70 outputs the telephone ring to the speaker 70 through the audio codec 60 and the audio amplifier 100, and the program of the telephone call controller 80. Create an environment where users can make phone calls.

At this time, the user must adjust the volume using the volume key 110 or a program mounted on the outside of the computer in order to reduce or mute the sound of music before answering the phone or during a phone call.

When the user manually lowers the volume by using the externally mounted volume key 110, the audio signal is output less through the amplifier 100, and when the user lowers the volume by using the keyboard or the mouse, the input volume control signal is input. It is input to the audio codec 90 via the output control hub 30, and the output signal of the audio codec 90 is reduced and output from the amplifier 100.

As such, the user has to manually lower the audio volume when a call is received through a modem while playing an audio signal, and adjust the audio volume to its original state after the call is over.

Accordingly, an object of the present invention is to reduce the size of the audio signal automatically when the telephone signal is input through the modem during the reproduction of the audio signal, so that the telephone signal is input when the call is terminated or the answering machine mode is performed. An apparatus and method for automatically adjusting the size of an audio signal according to a telephone signal for restoring the size of an audio signal in a previous state is provided.

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

2 is a schematic block diagram illustrating an audio signal automatic control apparatus according to a telephone signal according to the present invention.

An input / output control hub 30 for inputting an input unit 10 for inputting a signal from a keyboard or a mouse, a modem unit 20 for inputting a telephone signal, and an output signal of the input unit 10 and the modem 20. ), A memory control hub 40 for transmitting a signal output from the input / output control hub to a modem driver 50 to be described later, and a telephone signal output from the memory control hub 40 to the OS 70. The modem driver 50 for interrupting, the audio driver 60 for interrupting the audio signal output from the memory control hub 40 to the OS 70, and the audio signal when a telephone signal is interrupted from the modem driver 50. The OS 70 performs an automatic reduction program of the control unit 59 and reproduces the audio signal when the audio signal is interrupted from the audio driver 60, and the magnitude of the audio signal according to the control signal of the OS 70. To regulate It consists of a video signal control unit 200).

The operation of the apparatus and method for automatically adjusting the size of the audio signal according to the telephone signal according to the present invention configured as described above will be described in more detail with reference to FIG. 3.

3 is a flowchart illustrating a method for automatically adjusting the size of an audio signal according to a telephone signal according to the present invention.

When a call is received through a telephone line connected to the modem 20, the telephone signal is input to the modem driver 50 through the input / output control hub 30 and the memory control hub 40. The modem driver 50 interrupts the OS 70 when a telephone signal is input, and the OS 70 detects this and executes an audio signal automatic control program of the audio signal controller 200.

First, when the telephone signal is input (S10), the audio signal controller 200 checks whether the audio signal is currently being reproduced through the audio driver 60 (S20).

If the current audio signal is not playing, control the audio driver 60 to immediately output the ringing sound (S40). If the audio signal is currently playing, reduce the size of the audio signal (S30) and output the ringing tone loudly. In order to call the audio driver 60 (S40).

The audio driver 60 outputs a signal to the audio codec 90 to reduce the size of the audio signal and to output a loud ringing sound, and the audio codec 90 outputs the converted signal to the amplifier 100. 100 amplifies the phone ring sound with a small audio signal and outputs it to the speaker 120.

Next, a process (S50) of determining whether the user answers the call for a predetermined time is performed.

If there is a phone answer in the process (S50), the phone call control unit 80 is called to enable a phone call (S60).

Then, check whether the phone call is over (S70), and if the phone call is not over, determine whether the user manually adjusts the audio volume (S80), and if there is manual adjustment, call the audio driver 60 to adjust the audio volume. The process (S90) is performed.

If there is no telephone answer within the predetermined time in step S50, the auto answer mode is performed (S100).

If the phone call is ended or the answering machine is performed in step S70 (S100), the audio driver 60 is called to adjust the size of the audio signal to a state before the phone signal is input (S110).

As described above, the present invention automatically reduces the size of an audio signal when a telephone signal is input through a modem during the reproduction of the audio signal, and the size of the audio signal before the telephone signal is input when the call ends or the auto answer mode is performed. By adjusting it, the audio signal can be adjusted automatically instead of manually.
