Description

Automatic volume control device for audio equipment and its method {AUTOMATIC VOLUME SETTLING DEVICE FOR AUDIO DEVICES AND THE METHOD THEREOF}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic volume control apparatus and method for automatically outputting an audio device that receives an external input and modulates it, and specifically, automatically adjusts an input signal of various external audio devices having different output levels to a volume adjusted by a user. It relates to an automatic volume control device for audio equipment.

Recently, many audio devices such as a portable multimedia player (PMP), an MP3 player, and a car audio are provided. When these devices are output through other audio devices, for example, an MP3 player is output through a car audio. It is done frequently.

  However, each audio device such as a sound card, a portable MP3 player, and a car audio used in a PC has different characteristics such as an output level according to source conditions and recording conditions. Therefore, when each audio device is input as an external input and output to one audio device, there is a problem in that volume size, equalizer settings, and sound field effects must be adjusted manually each time the audio device is connected.

1 is a schematic diagram showing the configuration of a conventional audio modulation device, which is composed of a signal processing unit 120 and a control unit 110. Receiving a control signal from the control unit 110, the signal processing unit 120 modulates the signal from the external input to generate an output signal. The output signal is generated differently from the output level and characteristics of each device of the external audio device (for example, MP3 player, PMP, computer sound card, etc.) that is connected to the external input to input the signal. Therefore, the user has a problem in that the user has to adjust the level and characteristics of the audio output for each external input.

An object of the present invention is to output the audio as a sound set by the user even when receiving a variety of sound devices such as MP3, PMP, car audio by externally modulating and outputting the audio signal by the external input to the volume level specified by the user It is to provide a device and method that can be.

In order to achieve the above object, the automatic volume control device according to the present invention detects and transmits a first signal input through an external input to the control unit, and modulates the volume of the first signal to provide a second signal; A signal processing unit to generate, a second signal detection unit for detecting and transmitting the second signal output from the signal processing unit, and the first signal detection unit and the second signal detection unit in conjunction with the predetermined volume of the predetermined volume And a control unit for transmitting a control signal to the signal processing unit to modulate the second signal having a level.

According to another aspect of the present invention, there is provided an automatic volume control method comprising receiving preference sound information by a user, detecting a first signal input through an external input, and converting the first signal into the preferred sound information. And generating and outputting a second signal by modulating the second signal, and checking whether the second signal is modulated according to the preferred sound information.

As described above, the automatic volume control device for converting the output level of the various external audio device of the present invention to the volume level desired by the user may adjust the volume even when multiple external audio devices are used interchangeably. Volume adjustments can be made automatically without additional adjustments.

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

2 is a schematic diagram showing the configuration of an automatic volume adjustment device according to the present invention.

The controller 210 receives an input signal (hereinafter referred to as a first signal) and an output signal (hereinafter referred to as a second signal) from the first signal detector 230 and the second signal detector 240 to match the preferred acoustic information input by the user. Sends a control signal to the signal processor 220 to modulate. At this time, the controller 210 communicates a control signal with the signal processor 220 through I2C communication or other communication protocols.

In this case, the user's preferred sound information may include an audio volume output level or may further include equalizer, bass, sound field, and preferred sound information according to each music genre.

The signal processor 220 receives a sound signal from an external audio device, modulates it, and outputs the sound signal. The signal processor 220 exchanges data with an external device through Bluetooth wireless communication, near field communication, or wired serial communication (eg, RS232, USB communication, etc.). The external device refers to a means for storing audio data including both a portable storage device such as an MP3, a portable media player (PMP), a DVD, a CD-ROM, or a fixed storage device such as an HDD.

The first signal detector 230 detects a first signal input from an external device and transmits the first signal to the controller 210. The controller 210 compares the detected first signal with the preferred sound information input by the user, and transmits control information about the signal to the signal processor 220 when modulation is required.

The second signal detector 240 detects the second signal modulated by the signal processor 220 and outputs the second signal to the controller 210. The controller 210 determines whether the second signal is properly modulated according to the user's preferred sound information, and transmits the control information related to the signal processor 220 when the signal needs to be changed.

3 is a flowchart illustrating an automatic volume adjustment method according to the present invention.

The user inputs the preferred sound information to the control unit 210 (S301). The first signal detector 230 detects the first signal and transmits the first signal to the controller 210 (S302). The controller 210 transmits a control signal to the signal processor 220 to modulate the output signal based on the preferred sound information input by the user. The signal processor 220 generates a modulated first signal into a second signal based on the control signal received from the controller 210 and outputs the second signal (S303). The second signal detector 240 detects the second signal output from the signal processor 220 and transmits the second signal to the controller 210, and the controller 210 is adapted to the preferred sound information designated by the user. Check whether it is generated and output (S304).

The present invention has been described in detail with reference to the preferred embodiments and the accompanying drawings, which are merely exemplary, and those skilled in the art may various modifications therefrom within the scope of the technical idea of the present invention. And other equivalent embodiments are possible. Therefore, the scope of the present invention will be defined by the technical spirit according to the claims below.
