Description

APPARATUS AND METHOD FOR CONTROLLING A PLAYBACK FILE USING EARPHONE MAGNETIC}

The present invention relates to file play / pause, and more particularly, to an apparatus and a method for pausing a file currently playing due to earphone magnetism when an earphone approaches a player device, and a portable device including the same.

Currently, portable devices capable of viewing and directly using various information while moving are already common. The size of portable devices is also becoming smaller and lighter due to the development of manufacturing technology of various IC chips and internal components.

In particular, as technology advances, such portable devices will become more compact and convergent, and products with various designs and products will be developed.

Therefore, portable devices have evolved as a medium that can easily play a desired file while adding aesthetic accessories as well as a complex function by breaking away from a finished product equipped with a function of simply listening to music and watching a movie. . For example, designs are diversified, such as necklace-type designs and wristwatch types, and are evolving from easy-to-use key button arrangements and user interface applications.

As described above, the portable device has a small overall size for easy movement and portability. Therefore, the size of the operation device is very small. The smaller operation keys mean that the operation is not so easy. Although these days, the screen display itself is applied to the touch screen method that can selectively input information to emphasize the user's convenience, but when the touch screen itself is small, touch operation is inevitably difficult as with key operation.

Due to this problem, when listening to music or watching a movie using an actual mobile device's earphone and you need to temporarily stop playing the file due to something else, the user must confirm the pause key and press it. Due to the inconvenience of operation, most users do not operate the key, but instead of removing the earphone from the ear.

However, when only the earphone is removed from the ear, the A / V file being played is not stopped, and thus the A / V file cannot be viewed as much as the time when the earphone is inserted again from the time of removing the earphone. So most of the time the user is back to the file as much as the time he did not watch the situation is watching.

As such, when the user uses the portable device, the user cannot watch the A / V file being played for as long as the earphone is removed.

Accordingly, an object of the present invention is to provide an apparatus and method for controlling file playback using earphone magnetism such that the current file playback state is paused when the earphone removed from the ear approaches the portable device when the portable device is driven.

Another object of the present invention is to change the current pause mode back to the file playback mode when reusing the earphone.

According to the file reproduction control apparatus using the earphone magnet of the present invention for achieving the above object, the sensor means for detecting the earphone magnet; And a control means for changing the current file reproduction mode to a pause mode when the magnetic detection signal is applied by the sensor means and continuing to play the file from the paused time when the magnetic detection signal is not detected. .

According to another feature of the invention, the sensor means for detecting the earphone magnet; Detection means for detecting the magnetism by the sensor means for a predetermined time; And control means for changing the current file playback mode to the pause mode only when the detected magnetism is maintained for a predetermined time, and continuing to play the file from the pause point when the magnetism is not detected by the detection means. .

The sensor means is a magnetic Hall sensor whose output signal is changed by magnetism.

The sensor means outputs a 'level high signal' when detecting the magnetism.

The sensor means continuously outputs a 'level low signal' when the magnet is not detected.

If the magnetic means is not detected, the control means to play the file from a predetermined time before the pause time.

The control means changes to the power saving mode or turns the power off state when the pause mode has elapsed for a predetermined time or more.

According to still another aspect of the present invention, a reproducing file control device including the sensor means, a detecting means, and the like, and an earphone connected to an earphone terminal when reproducing a file using the reproducing file control device, are provided. When the proximity to the sensor unit is provided a portable device comprising a control means for pausing the current file playback operation by the earphone magnet.

According to the playback file control method for the earphone magnet of the present invention for achieving the above object, the magnetic detection step of the earphone in the file playback mode; Changing the file play mode to a pause mode once the magnetism is detected; And if the magnet is not detected, restoring the pause mode back to the file playback mode.

The mode change is made only when the magnetism is continuously detected for a predetermined time or more.

When the non-detection time of the magnetic body has elapsed for more than a predetermined time, the current pause mode is changed to a power saving mode.

When the non-detection time of the magnetic body has elapsed for more than a predetermined time, the current pause mode is turned off.

When the magnetism is detected, a 'level high signal' is output. When the magnetism is not detected, a 'level low signal' is output.

In the restoring to the file playback mode, the file playback is played back from a predetermined time before the pause time.

According to the present invention having such a configuration, when the earphone is removed from the ear while watching the A / V file of the portable device using the earphone, playback of the A / V file is automatically stopped, so that the earphone is used again. You can solve the problem of not being able to watch A / V files.

With reference to the preferred embodiment shown in the accompanying drawings and a portable device and method and control device for playing files using the earphone magnet according to the present invention will be described in detail.

In the present specification, a playback file control device will be described using a necklace type MP3 player as an example for convenience of description. In addition, the necklace type is a structure in which the earphone is connected to the main body and the earphone terminal of the main body, and when the earphone is not used reveals that the earphone is near the main body (see FIG. 3).

1 is a block diagram of an MP3 player according to a first embodiment of the present invention.

Referring to FIG. 1, the MP3 player 100 is provided with a sensor unit 102 for detecting the magnetism of the earphone 10 connected to the earphone terminal 101. The sensor unit 102 may be an element using an electromagnetic conversion principle for converting a magnetic signal into an electrical signal. That is, there are a magnetoresistive element, a magnetic transistor, and the like, which are described here as being provided with a magnetic hall sensor, and hereinafter also referred to as a magnetic hall sensor.

The magnetic hall sensor 102, in the characteristic, outputs a 'level high signal' when detecting the magnetism of the earphone 10, and outputs a 'level low signal' when the magnetism is not detected. The magnetic hall sensor 102 preferably outputs the level high signal only when the magnetic hall sensor 102 temporarily detects the magnetic field, but not the level high signal. This is because the magnetic Hall sensor 102 detects this and outputs a 'level high signal' when the medium having magnetism approaches the MP3 player 100 while the MP3 player 100 is normally operating. This is because a mode change to be described later may occur at this time. Therefore, it is preferable to limit the magnetic strength of the earphone 10 and to limit the magnetic strength of any one earphone among the pair of earphones. In addition, if it is assumed that there are many media having the magnetic strength of the earphone 10 around, it can be limited to the case where the magnetism is continuously detected for a predetermined time or more as in the second embodiment described later. This will be described in detail in the second embodiment.

When the 'level high signal' is applied according to the magnetic detection of the magnetic hall sensor 102, the controller 104 is configured to control the current mode change. The mode is divided into a file play mode and a pause mode. That is, when the magnetic hall sensor 102 detects the magnetism of the earphone 10 in the file reproducing mode, the controller 104 changes to the pause mode according to the 'level high signal', and the magnetism is not detected in the state. In this case, it changes from the pause mode to the file play mode according to the 'level low signal'.

In addition, the control unit 104 controls the power saving mode or the power-off in the pause mode when the pause mode starts to elapse for a predetermined time or more. The power saving mode may be applied in two or more steps as time passes. The time can be set by the user. To this end, a time setting unit 106 is provided.

The file playback and pause process according to the use of the earphone in the MP3 player having such a configuration will be described with reference to FIG.

Figure 2 shows a playback file control process using the earphone magnet in the MP3 player of Figure 1, Figure 3 is a state diagram using a necklace-type earphone to illustrate the present invention.

When the user operates the playback key with the MP3 player 100 around the neck, the controller 104 plays the selected file. The voice information of the reproduced file is output through the earphone 10 connected to the earphone terminal 101.

Then, for other tasks, for example, a person may have to take out the earphone 10 from his or her ear in order to talk with a neighbor or take a mobile phone. In this case, when the earphone 10 is detached from the ear by the user, the earphone is in close proximity to the magnetic hall sensor 102 of the MP3 player 100 as shown in FIG. 3.

The magnetic hall sensor 102 of the MP3 player 100 continues to perform the magnetic detection operation from the moment the file is played back. Thus, when the earphone 10 approaches, the magnetic hall sensor 102 Detects the magnetism generated from the earphone 10.

When the magnetic hall sensor 102 detects the magnetism, the magnetic hall sensor 102 outputs a 'level low signal' and then a signal changed to 'level high signal'. That is, the 'level low signal' is generated when the earphone 10 is fitted to the user's ear.

The 'level high signal' output from the magnetic hall sensor 102 is transmitted to the controller 104.

Then, the controller 104 controls to change the current mode of the MP3 player 100. That is, the controller 104 changes the current file play mode to the pause mode to pause the file play.

In other words, when the earphone 10 is removed from the user's ear and the earphone 10 comes to the magnetic hall sensor 102 of the MP3 player, the playback mode is temporarily stopped by the earphone magnetic detection operation of the magnetic hall sensor 102. The mode is changed to suspend mode. This is to stop the file playback during this time because the user can not listen to the playback file due to other things while the user removes the earphone 10.

When the user inserts the earphone 10 back into the ear, that is, when the earphone 10 is spaced apart from the magnetic hall sensor 102, the magnetic hall sensor 102 cannot detect the magnetism. Then, the magnetic hall sensor 102 outputs a 'level high signal' until before, and then changes the output to a 'level low signal'.

When the 'level low signal' is applied by the magnetic hall sensor 102, the controller 104 changes the mode from the current pause mode to the file play mode and replays the paused file.

Therefore, since the file is stopped during the time when the user does not use the earphone 10, and the file is paused again when the earphone 10 is used again, it is possible to solve the problem of not being able to listen to a predetermined portion.

On the other hand, when the mode is changed to the file stop mode, the control unit 104 counts the time from that time. Thus, when the time set by the time setting unit 106 arrives, the current pause mode is changed back to the power saving mode or the power is turned off.

When the file is being played and the 'level high signal' is output, the controller 104 stops playing the file, and stores the stopping time. When the 'level low signal' is output, the file is played back from the point in time before the stop point without playing the file directly from the point in time. This is because the playback file at the pause point cannot be properly listened to, so the playback file is played before the pause point.

Next, FIG. 4 is a block diagram of an MP3 player according to a second embodiment of the present invention.

The second embodiment is similar to the first embodiment. Therefore, detailed description of the configuration of the sensor unit 202, the control unit 206 and the like as the same configuration will be omitted. However, in the second embodiment, it should be noted that the mode is changed only when the magnetic detection time is maintained for a predetermined time.

The set time may be set by the user. This setting time is to prevent the mode change is easily made when the earphone 10 as well as other magnetic media approach the main body.

Referring to FIG. 4, when the earphone 10 connected to the earphone terminal 201 is in close proximity, the magnetic hall sensor as the sensor unit 202 for detecting the earphone 10 magnetism is provided, and the magnetic hall sensor 202 is provided. The signal generator 204 is configured to generate a signal for changing a mode only when the 'level high signal' generated by detecting the magnet is detected for a predetermined time or more.

When the first mode signal of the signal generator 204 is applied and the current playback mode is changed to the pause mode, and the level low signal is detected due to the non-magnetic detection, the first signal of the signal generator 204 is changed. A control unit 206 is provided to receive the two-mode signal and control the change back to the playback mode.

And the setting part 208 which adjusts a setting time is provided. The setting unit 208 may adjust the time from when the earphone 10 approaches the MP3 player 100 until the 'level high signal' is generated.

A process of playing and pausing a file according to the use of earphones in the MP3 player having such a configuration will be described with reference to FIG. 5.

5 illustrates a playback file control process using the earphone magnet in the MP3 player of FIG. 4.

First, the user operates the setting unit 208 to set the time T.

Then drive the MP3 player 200 while using the earphone (10). The file is output through the earphone 10 while playing the file.

While the file is being played, when the earphone 10 is spaced from the ear and near the MP3 player, the magnetic hall sensor 202 detects the magnetism generated by the earphone 10.

By the magnetic detection, the magnetic hall sensor 202 generates a 'level high signal'. The 'level high signal' is transmitted to the signal generator 204.

The signal generator 204 does not immediately generate a mode signal when the 'level high signal' is applied. The signal generator 204 determines whether the 'level high signal' is continuously applied for the time T set by the setting unit 208. If the 'level high signal' is continuously applied for the set time, the signal generator 204 outputs a first mode signal.

The first mode signal is applied to the controller 206. The controller 206 receives the first mode signal, and changes the current playback mode to the pause mode. The file playback is paused.

That is, the playback of the file is stopped for the time when the earphone 10 is separated from the ear.

Next, when the earphone 10 is plugged into the ear again, the magnetic hall sensor 202 cannot detect the magnetism. At this time, the 'level low signal' is directly applied to the signal generator 204 according to the detection result of the magnetic hall sensor 202, and the signal generator 204 outputs the second mode signal.

The output second mode signal is transmitted to the controller 206. The control unit 206 then returns the current pause mode to the playback mode. Therefore, the file is played again from the point of stopping. In this case, as in the first embodiment, the file can be played back from a time earlier than the playback stop point.

Although described with reference to the illustrated embodiment of the present invention as described above, this is merely exemplary, those skilled in the art to which the present invention pertains various modifications without departing from the spirit and scope of the present invention. It will be apparent that other embodiments may be modified and equivalent. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

For example, although the above-described embodiment describes the process of playing and pausing an audio file using an MP3 player, it should be noted that the process of playing and pausing a video file may be equally applicable. That is, when the video file is played using the video player, and the earphone is separated from the ear and approaches the video player as in the present embodiment, the pause mode of the video file currently played by the sensor means included in the video player. Is set, and when the earphone is used again, the paused video file is played again.
