Abstract

An MP3(Moving Picture Experts Group Audio Layer-3) player having a motion sensing function and a method for controlling the MP3 player are provided to play the MP3 player by sensing movement of an MP3 player body or by sensing movement of the body and an external object. A key input unit(101) generates a motion sensing mode signal and a play time setting signal at a motion sensing mode according to key operation of a user. A memory(102) stores an MP3 music file. A display unit(103) displays a current driving state and data, inputted by the key operation thereof, of a character type or an icon type. A motion sensing unit(104) senses positions and movement changes of an MP3 player body and an external object and generates an motion sensing signal in response to the sensed positions and movement changes. A control unit(105) sets a driving mode and play time according to the motion sensing mode signal and the play time setting signal, controls turning-on and off of an MP3 player in response to the motion sensing signal. A sound processing unit(106) converts the stored MP3 music file into an analog signal. An external device(107) outputs the analog signal as an audible signal.

The key input unit 101 generates a motion detection mode signal according to a user's key operation and a play time setting signal in the motion detection mode, and outputs the generated signal to the control unit 105. It includes function keys to perform, selection keys for selection and setting, and navigation keys.

The memory 102 serves to store MP3 music files.

In addition, the display unit 103 serves to display data input in accordance with the current driving state and the user's key operation in the form of a character or an icon, and a liquid crystal display (LCD) may be used.

The motion detection sensor unit 104 serves to detect a position or movement change of the MP3 main body or an external object, generate a motion detection signal according thereto, and output the same to the controller 105.

Here, the motion detection sensor unit 104 may be a recognition sensor for detecting the position or movement change of the MP3 main body when the user moves the MP3 main body, or may be configured as any one of the ultrasonic sensor for detecting the external movement, which is used Optional implementations are possible, depending on the desired form.

The controller 105 receives a motion detection mode signal and a play time setting signal in the motion detection mode from the key input unit 101 and sets a driving mode and play time according to the motion detection sensor unit ( It receives the motion detection signal from 104 and performs the MP3 play on / off control operation in the motion detection mode and outputs various control signals accordingly.

In addition, the sound processor 106 functions to decode the MP3 music file stored in the memory 102 according to the MP3 decoding method, convert the MP3 music file into an analog signal, and output the analog signal to the external device 107.

The external device 107 is connected to an output terminal of the sound processor 106 to output an analog signal of the MP3 music file input from the sound processor 106 as an audible sound.

Here, the external device 107 may be configured in the form of one or two or more of an earphone, a necklace string, and an external speaker into which the motion detection sensor unit 104 is inserted.

In addition, the mode setting key 108 is a function setting key for performing the operation sensing mode setting by an operation method other than the key input unit 101, and is preferably formed outside the MP3 main body.

In addition, the MP3 player of the present invention having the above-described configuration includes not only a USB port (not shown) for downloading MP3 music files through a computer or an internet network, but also includes all the basic configurations of an existing MP3 player. do.

Next, a control method of an MP3 player having a motion detection function according to an embodiment of the present invention having the above configuration will be described with reference to the accompanying drawings.

2 is an operation flowchart showing a control method of the MP3 player having a motion detection function according to an embodiment of the present invention, Figure 3 is an operation process added to the control method of the MP3 player having a motion detection function according to FIG. This is an operation flow chart.

First, the controller 105 receives a motion detection mode signal generated according to a user's operation and sets the motion detection mode according to the operation (S1).

At this time, the motion detection mode signal in the first step (S1) is a signal generated from one of the key input unit 101 according to the user's operation or the mode setting key 108 provided separately in the main body.

Thereafter, the controller 105 determines whether an operation detection signal is input (S2).

In this case, the motion detection signal in the second step (S2) is a signal generated from the motion detection sensor unit 104 for detecting a position or movement change of the MP3 main body, or an ultrasonic sensor (not shown) for detecting external movement. It is one of the signals generated from the motion detection sensor unit 104 having a).

In addition, the motion detection signal may be input from an external device 107 separately provided in addition to the MP3 main body, wherein the external device 107 is one of an earphone, a necklace string, and an external speaker into which the motion detection sensor is inserted. Or a combination of two or more thereof.

In this case, when the motion detection signal is not input in the second step S2, the process proceeds to the second step S2. When the motion detection signal is input, the controller 105 automatically turns on the MP3 player. ) "(S3).

In this case, the third step S3 automatically plays a preset MP3 file such as a song or a sound according to the user's operation when the MP3 player is "on".

Thereafter, in the state where the MP3 player is driven by detecting a change in position or movement in the motion detection mode as described above, the controller 105 determines whether a motion detection signal is input (S4).

At this time, the input of the motion detection signal determines whether the user is still in use when the play or operation is stopped, such as stopping after repeating the section, stopping after playing one file, and stopping after playing several designated files, and driving state accordingly. To change or keep the same.

At this time, if the motion detection signal is not input in the fourth step (S4), the controller 105 continues the MP3 player for that time in accordance with the play time setting in the motion detection mode which is preset according to the user's operation. After the play, the driving of the MP3 player is automatically "off" (S5).

At this time, the auto-off of the MP3 player is set in various ways such as 5 minutes, 10 minutes, 20 minutes depending on the time setting according to the user's operation, and stops after the section is repeated. Let the play state last for a certain time.

On the other hand, when the motion detection signal is input in the fourth step (S4), the control unit 105 maintains the current "on" driving state of the current MP3 player while the MP3 file such as a song or sound preset by the user Play (S6).

According to the MP3 player having a motion detection function and a control method thereof according to the present invention as described above, even if the user does not press the play button or does not use the scheduled time play function, the MP3 player can be automatically turned on or off through motion detection. New driving schemes.

Although the present invention has been described in more detail with reference to the examples, the present invention is not necessarily limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention.

As described above, according to the MP3 player having a motion detection function and a control method thereof, the driving of the MP3 player is automatically performed without direct manipulation by the user through the detection of motion or movement such as the position or movement of the MP3 player. By making it possible to turn on or off, there is an effect to make the user more convenient to use.

In addition, according to the present invention is to play by detecting the movement of the main body itself, or by the movement and motion detection of the main body and the external object is played when the parent shakes the mobile, the play is stopped when the motion is stopped For example, MP3 players and mobiles can be applied to a variety of applications such as infants and pets.
