Description

MP3 player having remote control function of a vehicle}

The present invention relates to an MP3 player, and more particularly to an MP3 player having a vehicle remote start and lock function and / or MP3 data FM transmission function.

MP (Motion Picture Expert Group Layer 3) players are widely used as devices for reproducing digital audio signals. Run in the form of a program (eg Winamp, JetAudio, WinPlay, XAudio, Mpplay, etc.) with a decoder to restore MP3 compression within the computer Unlike MP3 players, MP3 players implemented as individual devices such as cassette recorders or CD players are portable and various portable MP3 players have been developed.

The portable MP3 player starts from simply playing MP3 audio data, and stores audio data, connects to and receives data from an external electronic device such as a mobile phone or a PC, listens to radio, records voice, Various features such as multilingual support are being added. The addition of these features, combined with the portability of MP3 players, is becoming more practical, and the need to achieve a combination with other portable devices is increasing.

An object of the present invention is to meet the need for the combined function of the MP3 player, to provide an MP3 player with a remote start and lock function for the vehicle.

Another object of the present invention is to provide an MP3 player having a function of wirelessly outputting MP3 playback data.

MP3 playback apparatus according to the present invention includes an MP3 playback unit and a remote start and lock unit, the FM transmitter for outputting the MP3 output signal in the form of an FM signal that can be received by FM equipment or wireless earphone of the vehicle further It may include. The MP3 playback unit includes a controller for controlling the operation of the MP3 playback unit, an MP3 decoder for restoring the compressed MP3 data and converting the compressed MP3 data into an analog signal, and a key panel for receiving control command input data. The locking unit outputs a control signal for controlling the operation of the vehicle.

First embodiment

Hereinafter, a first embodiment of the present invention will be described with reference to FIG. 1.

MP3 player 100 according to the present invention includes a remote start and lock unit 80 and MP3 playback unit 120. The MP3 playback unit 120 includes a controller 10, a ROM 20, a memory interface 30, a key panel 40, an LCD 50, and an MP3 decoder 60.

The controller 10 outputs a control signal for controlling the overall operation of the MP3 playback unit 120. The control program of the control unit 10 is stored in, for example, the ROM 20. The controller 10 is connected to the memory device 90 through the memory interface 30 to read an MP3 file stored in the memory device 90, for example. The memory device 90 may include a flash memory and a smart media memory. In FIG. 1, the memory device 90 is shown to be configured outside the MP3 playback unit 120, but the memory device 90 may be included in the MP3 playback unit 120. The controller 10 retrieves the MP3 file from the memory device 90 based on the control command input data through the key panel 40 and delivers the MP3 file to the MP3 decoder 60. The MP3 decoder 60 restores the compressed MP3 file and converts it into an analog voice signal. The operation of the MP3 playback unit 120 may be output through the LCD 50. The USB port 80 connects an MP3 player to an external device such as a PC, downloads an MP3 file from the PC to the player 100 through the USB port 80, and plays music through a general voice output device (eg, earphone). Is output.

According to the first embodiment of the present invention, MP3 player 100 includes a remote starting and locking unit 80. The remote start and lock unit 80 outputs a control signal for remotely controlling the operation of the vehicle, for example, starting the vehicle engine or stopping the operation of the engine and locking the door of the vehicle. The remote start and lock unit 80 may share operating power through the power supply unit 70 and the power supply unit 70 of the MP3 playback unit 120. It is also possible to have separate power supplies for remote start and lock 80.

Since the MP3 player 100 according to the first embodiment of the present invention has not only the MP3 playback function but also the remote start and sleep function of the vehicle, the MP3 player 100 normally operates in the same manner as the general MP3 player and uses the vehicle. It also provides the ability to control the vehicle.

Second embodiment

2 is a block diagram showing the internal structure of the MP3 player 200 according to the second embodiment of the present invention. The MP3 player 200 according to the second embodiment includes an MP3 player 120, a remote start and lock unit 80, and an FM transmitter 130. In the configuration shown in Fig. 2, the same parts as those in Fig. 1 are denoted by the same reference numerals and detailed description thereof will be omitted.

The FM transmitter 130 includes an FM transmitter circuit unit (not shown) which receives an output signal of the MP3 decoder 60 of the MP3 playback unit 120 and converts it into an FM wireless signal, and converts the converted FM signal into an antenna 140. ) The user listens to the FM MP3 signal output through the antenna 140 of the FM transmitter 130 through a separate portable FM receiver, or adjusts the FM signal of the radio attached to the vehicle and outputs the output signal of the antenna 140.
