Abstract

A personally adjusted tone quality reproduction method of an audio device is provided to be capable of compensating a deficient band only to reproduce the compensated band by measuring personal hearing ability, thus loss of the hearing ability caused by an incorrect hearing method is prevented while personally adjusted tone quality is reproduced. After an earphone is inserted into an audio device, a hearing ability test unit of the audio device is selected and operated(310). The earphone is inserted into a user's ear, and a reproduction button of the audio device is operated(320). If a sound signal of a certain value is outputted from the audio device through the earphone, it is decided whether the signal is hearable(330,340). If not, the certain value is stored, and the certain value is increased(350). It is decided whether the increased value is larger than a reference value(360). If so, the user's hearing ability test results are inputted to a memory of the hearing ability test unit(370).

The present invention relates to a method for reproducing a personalized sound quality of an audio device, and more particularly, to an audio device for preventing hearing loss and reproducing a personalized sound quality according to a wrong listening method by measuring and reproducing only a lacking band by measuring individual listening ability. To personally play sound quality.

With the development of modern technology, useful devices for reproducing certain records as needed regardless of time and place have been widely used. With the development of digital technology, these devices are becoming smaller and larger, and are widely used to reproduce sound data. As described above, as the playback apparatus becomes smaller and larger in size, the user can carry the playback apparatus and play sound data regardless of time and place.

1 is a schematic block diagram showing a configuration of a general audio device.

Referring to the drawings, the audio device 10 includes an input unit 11, a volume control unit 13, an audio output unit 15, a setting value storage unit 17, and a control unit 19. The input unit 11 has a pause / release button 11a and a play button 11b.

The pause / stop button 11a is a button for pausing or terminating the playback operation of the audio device 10. The pause / stop button 11a is not used during the playback operation of the audio device 10. When it is pressed, the progress of the data which was in progress of reproduction is temporarily stopped. As the pause / cancel button 11a is pressed again, the pause of data reproduction is released and the reproduction is continuously continued.

The play button 11b is a button for reproducing data when the audio device 10 is powered off or stopped playing. In general, in the case of the audio device 10 that is implemented in an analog manner, data that has been interrupted according to the operation of the play button 11b proceeds continuously. In the case of the audio device 10 that is digitally implemented, the play button 11b. The data that was interrupted by the operation of) will be processed again from the beginning.

In addition, the volume control unit 13 controls the size of the output sound output to the sound output unit 15 of the audio device 10, and is generally implemented as a dial type to increase or decrease the size of the output sound according to the direction. Let's do it. The volume control unit 13 is implemented as two buttons in both directions, and may be implemented to indicate an increase or decrease in the sound size as the button is pressed.

In addition, the sound output unit 15 is generally implemented as an earphone or a headphone in a portable device such as an MP3 player, and may also be implemented as a speaker.

In addition, the setting value storage unit 17 stores the size of the output sound set by the volume adjusting unit 13, and stores only the sound size finally set by the volume adjusting unit 13, and thus, the setting value storing unit 17 ) Is typically implemented as a first-in first-out (FIFO) buffer.

The control unit 19 continuously reproduces the data of which playback has been paused when receiving a pause / release command from the pause / release button 11a in the pause state. When the reproducing section 19 receives the reproducing command from the reproducing button 11b, the reproducing data is replayed from the beginning or continuously according to the method taken by the audio device 10 again.

In addition, when the reproduction of data is paused after the pause in the audio device 10 or when the reproduction of the data is stopped and reproduced again, the controller 19 reproduces the sound at the size of the sound stored in the setting value storage unit 17. The size of the output sound of the output unit 15 is adjusted.

When the setting value storage unit 17 is omitted and the reproduction of the data is paused after the reproduction of the data in the audio device 10 is paused, or when the reproduction of the data is stopped and the reproduction is resumed, the control unit 19 changes the volume. It may be implemented to receive the size of the output sound set by the control unit 13, and to adjust the output sound output unit 15 to the size of the received output sound.

In the audio device 10 as described above, when playing in the normal mode, the basic sound quality is input through the input unit 11 as shown in FIG.

Then, the sound quality input through the sound output unit 15 is output as it is (step 120).

The listener hears the sound quality output as described above (step 130).

By the way, as shown in the signal diagram attached to the flowchart of FIG. 2, the input basic sound quality is output through the sound output unit 15 as it is, but each of the listeners have different hearing so that the output sound quality is the same. Can't listen

Similarly, as shown in FIG. 3, when playing back in the EQ (Equalizer) mode through the audio device 10, the basic sound quality is input through the input unit 11 (step 210).

The listener then selects a sound mode via the equalizer (step 220).

Then, the sound mode selected through the sound output unit 15 is implemented and output (step 230).

The listener hears the sound mode output as described above (step 240).

By the way, as shown in the waveform diagram attached to the flow chart of FIG. 3, as in FIG. 2, the sound is output through the sound output unit 15 as it is in the input sound mode. You cannot hear the same sound mode.

In other words, hearing is different from each other's ability as well as eyesight, while there are people who can hear well, while others do not hear well, so the same sound is applied equally, so that the listener feels a sense of discomfort with the constant sound output. It may be given to, or the hearing habits and methods are wrong due to the ignorance of the personal hearing ability, which causes hearing loss. In this case, the audio output unit 15 is an earphone or headphone for an MP3 player, which is widely used as a portable audio device. The direct sound can be heard more seriously. In this case, it can have a greater impact.

The present invention was created in order to solve the above problems, by measuring the individual listening ability to compensate for the insufficient band by playing back to prevent hearing loss according to the wrong listening method and to reproduce the personalized sound quality so that hearing is protected audio It is an object of the present invention to provide a personalized sound quality reproduction method of the device.

Personalized sound quality reproduction method of the audio device of the present invention for achieving the above object comprises the steps of: (a) inserting the earphones to the audio device, selecting and operating the hearing test unit of the audio device; (b) inserting the earphone into a user's ear and operating a play button of the audio device; (c) determining whether or not listening is possible when a sound signal having a predetermined value is output from the audio device through the earphone; (d) storing the predetermined value and increasing the predetermined value when the listening is not performed in the step (c); (e) determining whether the increase value increased in step (d) is greater than a reference value; (f) inputting a hearing test result of the user into a memory of the hearing test unit when the increase value is greater than the reference value in step (e); (g) pressing the play button of the audio device and playing the audio device; (h) converting the sound quality of the audio device according to the listening ability of the user and outputting the sound quality;

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

4 and 5a are schematic flowcharts sequentially showing a method for reproducing a personalized sound quality of an audio device according to the present invention, and FIG. 6 is an audio device to which a method for reproducing a personalized sound quality of an audio device according to the present invention is applied. A block diagram schematically showing the configuration of is shown.

Prior to the description, the same reference numerals as those in FIG. 6 denote the same members having the same functions.

Referring to each of the drawings, in the method for reproducing a personalized sound quality of an audio device according to the present invention, first, a user inserts an earphone into an audio device such as an MP3 player. That is, as shown in FIG. 6, the input terminal of the earphone corresponding to the sound output unit 25 of the audio device 20 is inserted into the output terminal of the audio device 20. Thereafter, the hearing test unit 24 of the audio device 20 is selected and operated.

Subsequently, after inserting the earphone into the user's ear, the play button (▶) 21b provided in the input unit 21 of the audio device 20 is operated.

When a sound signal having a predetermined value is output from the audio device 20 through the earphone, it is determined whether listening is possible (steps 330 and 340). That is, if a certain Hz and dB value are output from the audio device 20, the user is determined. Determine if it can be heard in the ear.

If it is not enough to listen in step 340, that is, if it is not heard, the constant value is stored in the memory of the hearing test unit 24, and the constant value is increased (step 350).

In addition, it is determined whether the increase value increased in step 350 is greater than the reference value.

On the other hand, as shown in Figure 7 in the step 330, the constant value is 100Hz, 60dB, and the increase in the constant value in step 350 is increased by multiplying the current Hz (100Hz) by two times. That is, as shown in FIG. 7, the initial Hz value (100 Hz) is multiplied by 2 and increased, wherein the Hz value is divided into six steps, for example.

In addition, when the increase value is greater than the reference value in step 350, the user's hearing test result is input to the memory of the hearing test unit 24. (Step 370) In step 370, the reference value is shown in FIG. , 3.2KHz.

Here, FIG. 7 described and described below is only one embodiment, and a user's hearing test may be performed by dividing into different Hz and dB values.

Subsequently, the play button 21b of the audio device 20 is pressed and the audio device 20 is reproduced so that the basic sound quality is input from the audio device 20 (step 410). As shown at right of step 410 of FIG. 5A. Similarly, the corresponding signal diagram in each step described later is shown on the right side.

Then, the sound quality of the audio device 20 is converted and output by the customized EQ unit 26 of the audio device 20 according to the listening ability of the user. (Steps 420 and 430).

Since the customized EQ unit 26 in step 420 takes into account the user's hearing test data input to the hearing test unit 24 and converts the corresponding EQ and Hz values into the corresponding Hz and dB values, and outputs them through the sound output unit 25. Step 430 is possible.

Then, the user hears the sound that is changed and output according to his / her listening ability (step 440).

On the other hand, if it is determined in step 340 that listening is not possible, i.e., when an output sound is heard, the dB value of the predetermined value is reduced and then step 330 is performed again (step 610). The dB value is reduced by -5 dB, as shown in FIG.

In addition, the constant value, the reference value, and the increment value are displayed on the display unit 22 of the audio device 20 so that each value and the change value can be easily tested by the user.

In another embodiment of the present invention, as shown in FIG. 5B, the process up to step 370 is the same as the above-described embodiment. Therefore, the same process will be referred to the foregoing and will be omitted here.

After the step 370, the play button 21b of the audio device 20 is pressed, and the audio device 20 is reproduced so that the basic sound quality is input from the audio device 20 (step 510).

In addition, the user of the audio device 20 selects and plays the sound mode using the EQ mode of the audio device 20 (step 520).

Then, the sound quality is converted and output by the customized EQ unit 26 of the audio device 20 according to the listening ability of the user. (Steps 530 and 540).

Then, the user hears the sound which has been changed and output in accordance with his listening ability (step 550).

As described above, the method for reproducing the personalized sound quality of the audio device according to the present invention is to control the sound in the audio device 20 having the sound output so as to be reproduced according to the individual listening ability. Users to listen to the audio device 20 is to make it possible to hear the correct original sound.

This will be described in more detail.

First of all, the individual listening ability is measured by audible frequency band 20Hz to 20KHz (actually 20Hz to 16KHz) in 12 stages. In this way, we measure the lowest sound pressure that the listener can hear at each frequency level.

And the measuring method can be divided into several methods depending on the sound equipment (audio device) used.

First, in the case of HTS (Home Theater System) or Mini Audio, the signal is played from the set to the headphone or the main speaker from the basic sound to the small sound, and the listener signals the set from the limit sound to the remote control. It also visually shows playback on the set's display during step-by-step sound playback.

And in the case of an MP3 player, the signal is played from the set to the earphones or external speakers from the base to the small tones and the listener signals the set at the threshold. Visually playing during sound playback.

The above listening test is a more accurate and scientific way to connect with a hearing aid company or hospital to measure in an accurate environment, the data can be downloaded and used on a CD or USB.

You can also adjust the basic EQ by referring to the listening ability data of each individual (user).

As described above, the personalized sound quality reproduction method of the audio device according to the present invention has the following effects.

Hearing is also different from each other, such as eyesight, there are people who can hear well and people who do not hear well, and eyesight is not good to see well, the present invention is to listen to each person (user) in the audio device Anyone can feel the original sound by allowing the sound to be reproduced in consideration of the ability.

In the related art, ignoring a person's listening ability, and having a bad listening habit by uniformly reproducing a sound in an audio device, caused hearing damage, but protects the hearing by reproducing the sound according to each person's listening ability as in the present invention. can do.

Earphones or headphones that listen to direct sound are more damaging to hearing, and audio devices that don't have separate EQ (band-by-band) are more effective.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
