Abstract

A portable digital sound player including a conventional MP3 player has the same configuration as a conventional portable cassette player (Walkman). That is, a player set for reproducing a digital sound source and a headphone set or earphone set for listening to a sound source reproduced in the player and a connector wire for connecting the player and headphone set to the earphone set. Due to these components, there was an inconvenience in proper carrying and storing the player and the connector wire during exercise or outdoor activities.

In order to solve the inconvenience as described above, the present invention allows the digital sound source player to be built into the headphone set to listen to the digital sound source without a separate player or connector wire, thereby maximizing activity during exercise or outdoor activities, and Convenience can also be achieved. In addition, the present invention can be implemented with the function of the existing headphone by performing only a simple headphone function when using a general acoustic device.

In order to achieve the above object, a detailed configuration and operation of the present invention will be described with reference to the accompanying drawings.

FIG. 1 illustrates a player 400 for reproducing a digital sound source downloaded from the Internet as an example of a conventional digital sound player, and an operation key 407, a display unit 405, an earphone jack 404, and an operation key. Locking device 406 for preventing a key malfunction that may occur during movement or storage of the 407, a headphone set 401 for listening to the reproduced sound source, and a connector for connecting the player 400 and the headphone set 401 Consists of a wire 402, using a fixing clip 408 attached to the back of the player 400 for carrying around the waist with the inconvenience of carrying when exercise or outdoor activities, or the case 409 made of leather or cloth member The regenerator 400 was put into the suture using a string member 410, there was a inconvenience to move or store.

Figure 2 is a system configuration according to an embodiment of the present invention to eliminate the inconvenience of the conventional digital sound player as described above to listen to the digital sound source including the MP3 with only one headphone set 100 having a built-in digital sound player It was. The headphone set (hereinafter referred to as "built-in headphone") incorporating the digital sound source player executes operations with a variable volume 110 whose volume is adjustable and an interface connector 101 for receiving sound from a sound source supply device such as a computer. PLUG TO PLUG connector 200 in order to use the built-in headphones as simple headphones, such as ordinary headphones, by connecting the execution key 104 and other audio devices 300 to 301 to listen to the sound source of the cassette or the sound card of the computer. 3.5mm input jack 115 for inserting the battery, battery compartment 112 for accommodating the battery and the built-in headphone 100 can be selected as a digital sound source playback mode and a normal headphone mode ( 113) and an LED 102 capable of displaying the remaining light of the battery.

3 is a block diagram showing a specific configuration of the present invention with reference to this in detail as follows.

The digital sound source input through the interface unit 101 is stored in the memory unit 105, and the microprocessor 103 recognizes the operation selection of the key input unit 104 and stores the sound source stored in the memory unit in the digital sound source decoder unit ( In step 106), the compressed sound source is released. The sound source decoded by the digital sound source decoder 106 is converted into an analog signal form by the D / A converter 107, and the amplification unit 108 performs the VOLUME 110 variable, and then through the selection unit 109 through the headphone speaker. It is output through 111. If only a simple headphone function for listening to a sound source of another audio device is reproduced during the digital sound source reproducing operation as described above, when the external input forced selection unit 113 is switched to the normal mode, the external input forced selection unit 113 is connected to the power supply unit 112. Control to execute the power-off to stop the execution of the digital sound source, and select the other sound source input to the 3.5mm input jack 115 from the other sound device 300 through the PLUG TO PLUG connector 200. Gina can be output through the headphone speaker 111. In addition, the digital input source has an external input detection unit 114 that can automatically discriminate external input even in the playback mode, so that when there is an external input, the power to perform only a part of functions such as an interrupt part of the microprocessor of the player, not the power off. You can also output an external sound source at the same time as executing the power saving mode.

4 is a flowchart illustrating a driving method of the present invention, in which an external input forced selection determination step (S10) for determining a forced selection of the external input forced selection unit (113) and a player power down when an external input is selected (S20) and headphones The external input detection determination step of automatically determining the external input by the external input detection unit 114 in the player mode in the step (S30) and the external input forced selection determination step (S10) of outputting through the speaker ( S40) and if the external input is detected in the determination step, putting the player into a power saving mode (S50), outputting the external input (S60), and reproducing the device if there is no external input in the external input detection determination step (S40). Selection to execute the selection mode when the operation is selected in the operation key selection determination step (S70) and the operation key selection determination step (S70) for determining whether to select the operation key. It consists of a mode execution step S80.

Fig. 5 is a block diagram showing a further possible embodiment of the present invention, showing a further possible embodiment of a headphone set incorporating the digital sound player described above. First, the headphone type 100 which forms the fixed head on the upper side of the user's head, and the headphone type 150 which fixes the built-in headphone using the rear side of the user's head and the user's axle, and the operation unit of the built-in headphone described above. And it is possible to add an embodiment using the earphone type 160 that can be located in the upper side or the side of the head of the user and can use the receiver of the earphone type.

As described above, the conventional digital sound source player comprises a player set for reproducing a digital sound source, a headphone set or earphone set for listening to a sound source played in the player, and a connector wire connecting the player and headphone set to the earphone set. . Due to these components, there is an inconvenience of proper carrying or storing the player and the connector wire during exercise or outdoors. The present invention eliminates this inconvenience of the conventional player, provides activity and convenience in sports or outdoor activities, and at the same time has the effect of performing a simple headphone function when using other audio equipment.
