Description
Technical field
The utility model relates to Bluetooth wireless technology, is specially the device of a kind of integrated with Bluetooth earphone and MP3 player.
Technical background
Bluetooth (Bluetooth) technology is a kind of the short distance wireless communication technology standard.
Bluetooth technology is social as a kind of standard configuration of mobile phone now, and increasing mobile phone has also possessed Bluetooth function.Advantages such as Bluetooth technology is wireless with it, radiation proof are accepted by increasing people, and the market demand becomes tangible ascendant trend.
MP3 of the prior art have beat answer the call, listen to the music, by the function of USB interface as USB flash disk.But do not support to carry out wireless downloading and exchanges data with computer, PDA, mobile phone with Bluetooth function.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of device that bluetooth earphone and MP3 player are integrated, this device has bluetooth earphone function and MP3 function simultaneously, and computer, PDA, the mobile phone supporting and have a Bluetooth function carry out wireless downloading and exchanges data, and have both the two some advantages simultaneously, and as: it is little, easy to carry, easy to use etc. to need not complex drive mechanism, volume.
To achieve these goals, as shown in drawings, the technical solution adopted in the utility model is as follows: bluetooth MP3 player, comprise Bluetooth chip, MP3 processor, antenna, and wherein antenna links to each other with the radio frequency interface of Bluetooth chip by radio frequency line; It is characterized in that: the USB pin of MP3 processor connects USB interface, and the MP3 processor links to each other with LCD display with USB flash disk 15 by its address/data bus, and selects by chip selection signal; The MP3 processor passes through I
2The C bus links to each other with Bluetooth chip, carries out exchanges data, and links to each other with the SPEAKER mouth of Bluetooth chip by the phonetic entry mouth; The MP3 processor connects microphone and loudspeaker by its analog audio interface, and Bluetooth chip also connects gram wind and loudspeaker by its analog audio interface.
Said structure passes through I because bluetooth earphone and MP3 player are integrated
2C interface is realized communication between the two, exchange message, realize both synchronously.Its advantage is: have bluetooth earphone function and MP3 function simultaneously, when when incoming call can automatic pause MP3 broadcast, and can on the MP3 display screen, show caller ID, incoming call person's name information such as (needing incoming call to deposit cellphone directory in), and browse cellphone directory by the MP3 display screen, dial the number of typing phone directory, last outgoing call such as redials at function.
