The circuit of the MP3 player 1 contains a digital signal processor 11 with a keyboard 12 , through which the command can be entered, an LC display 13 , a microphone 14 , a store 15 , in which data and programs are stored, a loudspeaker 16 and an earphone 17 connected is. The digital signal processor 11 can through the keyboard 12 command entered and that through the microphone 14 Recorded input audio signals and the MP3 data from the memory 15 read or in memory 15 lay down. The digital converter can also 11 the corresponding information on the display 16 view and the decompressed analog signals to the earphones 17 send.

The first radio transmitter / receiver module 2 is internally or externally with the digital signal processor 11 of the MP3 player 1 connected. This first radio transmission / reception module 2 is used to receive the audio data from the digital home device 3 and for sending the decompressed audio data of the MP3 player 1 to the digital home device 3 , In the present exemplary embodiment, the first radio transmission / reception module 2 a Bluetooth module that has a chipset and can transmit digital data over the frequency of 2.45 MHz.

In the present exemplary embodiment, the digital home device can be an audio or video device, such as a television, stereo system, multimedia product, etc. The circuitry of the digital home device 3 contains a control circuit 31 that with a power switch 32 , a sound output circuit 33 which allows you to adjust the volume and a memory 34 , in which data and programs are stored. Based on the input command, the control circuit 31 eg the power switch 32 Press, adjust the volume or search for the station.

The second radio transmitter / receiver module 4 is with the control circuit 31 and the sound output circuit 33 connected. This second radio transmitter / receiver module 4 can receive the signals from the first radio transmission / reception module 2 received and sent to the control circuit 31 send. The digital audio signals from the sound output circuit 33 can be transmitted to the first radio transmission / reception module, which then transmits these audio signals to the digital signal processor 11 of the MP3 player 1 sends where the digital audio signals are converted to analog audio signals and then sent to the earphones 17 be sent. In the present exemplary embodiment, the second radio transmission / reception module 4 a Bluetooth module that has a chipset and can transmit digital data over the frequency of 2.45 MHz.

If the digital signal processor 11 of the MP3 player 1 through the keyboard 12 receives the command entered and via the first and second radio transmission / reception module 2 . 4 to the control circuit 31 sends, the control circuit 31 according to the command the power switch 32 Press, adjust the volume or search for the station.

When the digital audio signals of the digital home device 3 via the second radio transmission / reception module 4 to the first radio transmission / reception module 2 can be sent, the digital signal processor 11 of the MP3 player 1 perform a conversion to analog audio signals and these audio signals to the earphones 17 send for the user.

In 3 Another embodiment of the invention is shown, in which the digital home device 3 with one connection 35 is provided, via which the second radio transmission / reception module 4 with the digital home device 3 is connected externally. This allows the digital audio signals of the digital home device 3 via the second radio transmission / reception module 4 to the first radio transmission / reception module 2 be sent. Then the digital signal processor 11 of the MP3 player 1 perform a conversion to analog audio signals and these audio signals to the earphones 17 send for the user.

In summary it can be stated that the invention a wireless signal transmission allowed between an MP3 player and a digital home device. Due to the above facts, the invention corresponds to their availability, progressiveness and novelty fully meets the requirements for a utility model.

The above description presents only the preferred embodiments the invention and is not intended as a definition of the limits and serve the scope of the invention. All equivalent changes and modifications belong within the scope of this invention.

The invention thus relates to a Signal transmission device between a digital home device and an MP3 player, which has an MP3 player, a first radio transmission / reception module, a digital home device and a second radio transmission / reception module. The first radio transmitter / receiver module is connected internally or externally to the MP3 player and the second radio transmitter / receiver module is connected internally or externally to the digital home device. This allows between wireless signal transmission for the MP3 player and the digital home device respectively.
