DE20317855U1 - Multiplayer reads music from digital source connected to input port and converts to radio transmission for reception by radio receiver - Google Patents

Abstract

A multiplayer reads music data from an external storage medium such as MP3 player, CD player or memory card through a port (31) under control of a processor (34) for conversion to radio frequency and transmission using high frequency, infrared, laser, Bluetooth or similar link.

Description

technical area

The invention relates to a multiplayer, which has a digital / analog / radio frequency conversion unit, which the digital (or analog) music data on radio frequency signals can implement that received by a radio or a radio receiver and can be played.

State of the art

In earlier times, a tape recorder or a Turntable used to be in a tape or vinyl record play recorded music. The tape and the record are lock and are therefore difficult to store. Therefore developed the magnetic cassette and the optical CD. In the Cassette can detach the magnetic powder after a long period of operation, see above that the music quality is reduced. Compared to the magnetic cassette points the CD has a smaller volume and a larger storage capacity. In Recently, a new storage medium, the flash memory, developed, which in comparison with the CD an even smaller volume and has an even larger storage capacity and is for playing and storing multimedia data (such as MP3 data used. The cassette, CD and MP3 music data are all in stored in digital or analog form. This music data can only by a corresponding player, such as a cassette player, CD player and MP3 players.

Task of invention

The invention is based on the object to create a multiplayer that has a digital / analog / radio frequency conversion unit has the digital (or analog) music data on radio frequency signals can implement that received by a radio or a radio receiver and can be played.

This task is accomplished by the multiplayer according to the invention solved, a reading unit, a processing unit, an implementation unit and has a transmission unit, wherein the processing unit Activate the reading unit to read the digital / analog music data and send the read music data to the conversion unit can where the digital / analog music data on radio frequency signals are implemented and then sent out by the transmitting unit. This music data implemented in the form of radio frequency signals can be from a radio or a radio receiver received and played.

The above reading unit can the music data in an MP3 player, a CD player, a memory card or read in a hard disk.

Ways to Execute the invention

Referring to 1 and 2 there is the multiplayer according to the invention 10 essentially from an upper cover 10 , a circuit board 30 and a base plate 40 , The top cover 10 and the base plate 40 can be connected together and the circuit board 30 enclose. The top cover 10 and the base plate 40 each have a recess on the same side 21 . 41 for the port 31 the circuit board 30 to connect to an external storage medium 50 serves ( 3 ).

At the port 31 can be COM1, memory card slot, USB, IEEE1394 or IDE interface. The digital / analog signals are sent via the port 31 on the processing unit 34 the circuit board 30 transfer. The circuit board 30 has a power connector 32 that is used to connect to the power source.

The circuit board 30 ( 3 ) comprises at least one reading unit 33 that with the port 31 is electrically connected and through the port 31 the music data in the external storage medium 50 can read a processing unit 34 that the reading unit 33 control for reading the digital / analog music data and the read music data to the implementation unit 35 can send an implementation unit 35 which can convert the digital music data to analog signals and then convert the analog signals to radio frequency signals or convert the digital or analog music data directly to radio frequency signals, and a transmitting unit 36 which amplifies and transmits the radio frequency signals.

Any receiving device 60 (Like a radio) with a modulated reception frequency, this music data can be received and played in the form of radio frequency signals.

How out 4 can be seen, the multiplayer 10 over the port 3l connected to the computer to access the music data (such as MP3 or WMA music data) in the computer, or to an external storage medium 50 (how CD player, MD player, MP3 player, memory card, Walkman) can be connected, creating the reading unit 31 the digital (or analog) music data in the external storage medium 50 can read. When used, the processing unit sends 34 by the reading unit 31 read digital or analog music data to the implementation unit 35 where this digital or analog music data is converted to radio frequency signals and then by the transmitter unit 36 be sent out. The receiving device 60 can on the transmission frequency of the transmission unit 36 are provided, whereby the music data in the form of radio frequency signals from the receiving device 60 can be received and played.

In 5 Another embodiment of the invention is shown in which the multiplayer 70 with a plug 71 is combined, which can be inserted into the cigarette lighter of the vehicle (not shown), whereby the car battery is used as the power source of the multiplayer. The music data converted to radio frequency signals can be from the car radio 80 received and played through the speakers.

The multiplayer according to the invention has at least a storage unit with the external storage medium Can exchange data.

The wireless transmission by the transmitter unit can be a radio frequency, infrared, laser, bluetooth or other transmission his.

The reading unit 33 , the implementation unit 35 and the transmitter unit 36 can also in the processing unit 34 to be built in.

Due to the above facts corresponds to the invention in its availability, progressiveness and novelty fully on 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.
