In addition to the TV, various electronic devices, such as a computer and an audio, are also made of a plurality of electronic components, and a fan for heat generation is mounted therein.

However, the fan as described above has the characteristic that the electronic device is always rotated at a constant speed while the electronic device is being driven. When the sound output through the speaker of the electronic device is reduced due to the rotational characteristic, the fan's rotation sound is transmitted to the user. There was a problem hearing.

 The present invention has been made to solve the above problems, an object of the present invention to provide an electronic device and method that can automatically adjust the rotational speed of the fan in proportion to the volume of the sound output through the speaker.

Another object of the present invention is to provide an electronic device and a method capable of preventing the rotation sound of the fan from being heard by the user by automatically adjusting the rotation speed of the fan in proportion to the volume of the sound output through the speaker.

Another object of the present invention is to provide an electronic device and a method for reducing the amount of power consumed by the rotation of the fan by automatically adjusting the rotation speed of the fan in proportion to the volume of the sound output through the speaker.

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

1 is a block diagram of an electronic device for automatically adjusting the rotation speed of the fan in an embodiment of the present invention.

Referring to FIG. 1, the electronic device 100 of the present invention includes a fan 101 for generating heat generated by an internal electronic component, a speaker 102 for outputting a sound signal to the outside, and a sound. Control unit 103 for controlling the output of the signal and controlling the rotational speed of the fan 101 according to the magnitude of the sound signal output through the speaker 102, and makes the sound signal to the signal suitable for the speaker 102 An audio processor 104 is provided.

Since the fan 101 includes a rotating motor (not shown) that rotates by a current applied by the control unit 103, the fan 101 rotates at a constant speed according to the control of the control unit 103, and thus, the inside of the electronic device 100. It generates heat generated by. In addition, since the rotation speed is determined by the magnitude of the applied current, the rotation motor rotates relatively quickly when a high current is applied, and rotates relatively slowly when a low current is applied.

When the user instructs the user to increase the volume of the output sound, the controller 103 increases the amount of current output from the audio processor 104 to the speaker 102 in proportion to the volume of the sound, and is simultaneously applied to the rotating motor of the fan 101. The amount of current also increases in proportion to the volume of the sound.

When the user instructs the user to reduce the volume of the output sound, the control unit 103 reduces the amount of current output from the audio processing unit 104 to the speaker 102 in proportion to the volume of the sound, and at the same time to the rotating motor of the fan 101. The amount of current applied is also reduced in proportion to the volume of the sound.

2 is a configuration diagram of a television receiver to which the present invention is applied.

Referring to FIG. 2, the television receiver 200 includes a tuner 201 for receiving a composite video signal transmitted from a broadcasting station and outputting an analog video signal and an audio signal, and a screen 202 for displaying the video signal. And a speaker 203 for outputting an audio signal, an A / D converter 204 for converting an analog video signal output from the tuner 201 to a digital video signal, and an A / D converter 204. A video processing unit 205 for making a digital video signal into a signal form suitable for the screen 202, an audio processing unit 206 for making an audio signal output from the tuner 201 into a signal suitable for the speaker 203, and a composite The controller 207 and the video processor 205 for controlling the reception and output of the video signal, and for controlling the magnitude of the video signal output from the video processor 205 and the audio signal output from the audio processor 206. A video output unit 208 for outputting the output video signal to the screen 202, an amplifier 209 for amplifying the audio signal output from the audio processing unit 206 to the speaker 203, and a controller 207; It is provided with a fan 210 for driving heat generated by the current applied by the heat generated inside.                     

The tuner 201 receives a composite video signal transmitted through a plurality of channels, and outputs a composite video signal of a channel to which the control unit 207 instructs output of the received channel. In this case, the tuner 201 outputs an analog video signal included in the composite video signal to the A / D converter 204 and outputs an audio signal to the audio processor 206.

The video processor 205 converts the digital video signal converted by the A / D converter 204 into a signal suitable for the screen 202 under the control of the controller 207 and outputs the signal to the video output unit 208.

The audio processor 206 converts a voice signal output from the tuner 201 into an electric voice signal suitable for the speaker 203 under the control of the controller 207, and outputs the voice signal to the amplifier 209, but controls the control unit 207. The intensity of the current applied to the speaker 203 is adjusted accordingly. That is, when the audio processor 206 increases the amount of current applied to the speaker 203, the volume of the sound signal output through the speaker 203 also increases, and conversely, the amount of current applied by the audio processor 206 to the speaker 203 is increased. When it decreases, the magnitude | size of the sound signal output through the speaker 203 also becomes small.

When the user instructs the user to increase the volume by using a remote controller or the like, the controller 207 increases the amount of current output from the audio processor 206 to the speaker 203 in proportion to the volume, and simultaneously applies the amount of current applied to the fan 210. Also increase in proportion to the volume of the sound.

When the user instructs the user to decrease the volume, the controller 103 reduces the amount of current output from the audio processor 206 to the speaker 203 in proportion to the volume of sound, and at the same time, the amount of current applied to the fan 210 is also reduced. Reduce in proportion to size                     

The fan 210 has a rotating motor (not shown) that rotates by a current applied by the control unit 207. Since the rotating speed is determined by the magnitude of the applied current, the high speed is applied. It rotates relatively fast and rotates relatively slowly when a low current is applied.

3 is a flowchart illustrating a method for automatically adjusting the rotation speed of a fan according to an embodiment of the present invention.

Referring to FIG. 3, in a state in which the electronic device 100 outputs a sound signal through the speaker 102, when the user instructs to increase the volume (S301), the electronic device 100 controls the speaker 102. Increasing the output sound and at the same time increasing the amount of current applied to the fan 101 also increases the rotational speed of the fan 101 (S302).

Then, when the user instructs to decrease the volume (S303), the electronic device 100 reduces the sound output through the speaker 102 and at the same time reduces the amount of current applied to the fan 101 to rotate the speed of the fan 101. It also reduces (S304).

As described above, when the sound output through the speaker 102 is increased, even if the rotation speed of the fan 101 is increased, the sound generated by the speaker 102 is very loud, so that the rotation sound of the fan 101 is transmitted to the user. I can't hear it.

In the present invention, when the rotation speed of the fan 101 is reduced in proportion to the sound output through the speaker 102, the rotation sound of the fan 101 is not heard by the user by the sound output through the speaker 102. Reduce the rotation speed of the fan 101 to the extent that it does not.                     

Although the technical spirit of the present invention has been described in detail according to the above-described preferred embodiment, it should be noted that the above-described embodiment is for the purpose of description and not of limitation. In addition, those skilled in the art will understand that various embodiments are possible within the scope of the technical idea of the present invention.

As described above, the present invention automatically adjusts the rotational speed of the fan in proportion to the volume of the sound output through the speaker, so that the rotational sound of the fan is not heard by the user, and the user's convenience is further improved. This can prevent unnecessary power consumption.
