The MP3 processor is connected with the Bluetooth chip through an I2C bus, and is connected with a speaker port of the Bluetooth chip through an audio input port. An antenna is connected with a radio frenquency interface of the Bluetooth chip through a radio frenquency cable. Integrating the MP3 player and the Bluetooth USB adapter together, the utility model realizes communication between the MP3 player and the Bluetooth USB adapter through an I2C interface. The utility model has the advantage that the utility model has the functions of a Bluetooth earphone and the MP3 player and can automatically suspend playing of the MP3 player when a phone call, and information such as an incoming call number, the name of a caller, etc. can be displayed on an MP3 display, and has the functions of displaying a mobile phonenumber book, dialing the numbers recorded in the phone number book, redialing a last dialed number, etc. through an MP3 synchronizing mobile phonenumber book, and has the advantages of no need of complicated driving mechanisms, small size, convenient operation, portability, more functions, etc.
Description
Technical field
The utility model relates to a kind of multi-functional MP3 player, the MP3 player of especially a kind of integrated with Bluetooth earphone/hands-free, bluetooth USB adapter.
Technical background
In the prior art, MP3 have listen to the music, by the function of USB interface as USB flash disk, but do not support dialing/receiving telephone, with mobile phone realize wireless messages synchronously, correlation functions such as exchanges data and bluetooth USB adapter.
Bluetooth (Bluetooth) technology is a kind of the short distance wireless communication technology standard, in society now as a kind of standard configuration of mobile phone, 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 is tangible ascendant trend.What Bluetooth technology was most widely used at present is mobile phone, can use bluetooth earphone when making a phone call, and when setting up communication link transmission picture or synchronizing information with PC, needs to use bluetooth USB adapter.But existing bluetooth USB adapter is an independently product, how with bluetooth USB adapter and bluetooth earphone/hands-free and multi-functional product of MP3 player combination formation, is the problem that one of ordinary skill in the art never are resolved.
Summary of the invention
Independent separately at bluetooth USB adapter, MP3 player and bluetooth equipment in the prior art, make troubles to the user, and use a plurality of products can increase the deficiency of cost separately, the purpose of this utility model provides a kind of with bluetooth earphone/hands-free, bluetooth USB adapter and the integrated device of MP3 player.
The purpose of this utility model is achieved in that the bluetooth MP3 player of band bluetooth USB adapter functions, comprises USB interface, button, Bluetooth chip, microphone, MP3 processor, antenna and commutation circuit; USB interface links to each other with commutation circuit by the USB interface connecting line; Commutation circuit connects Bluetooth chip and MP3 processor respectively; The MP3 processor passes through I
2The C bus links to each other with Bluetooth chip, and links to each other with the SPEAKER mouth of Bluetooth chip by the phonetic entry mouth; Antenna links to each other with the radio frequency interface of Bluetooth chip by radio frequency line; Microphone is directly connected to the analog audio interface of Bluetooth chip and MP3 processor; The Speaker output signal of Bluetooth chip is input to the MP3 processor, switches in MP3 processor inside; Commutation circuit is by pressing key control selection and USB flash disk or bluetooth USB adapter; The MP3 processor also links to each other with LCD display with Flash Memory by address/data bus; The MP3 processor connects microphone and loud speaker by its analog audio interface, and Bluetooth chip also connects microphone by its analog audio interface.
The utility model is by the configuration combination of above-mentioned hardware, and detecting a certain pin by the program of Bluetooth chip is high (or low) level; By detecting the variation of level, hot reset is carried out in storage one " sign " in Flash; Switch to MP3 function or bluetooth USB adapter functions according to the sign in the Flash again behind the hot reset.
Said structure passes through I because bluetooth 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 by the synchronous cell-phone telephone book of MP3, show cellphone directory, dial the number of typing phone directory, last outgoing call such as redials at function.
The utility model only uses a Bluetooth chip, realizes the function of bluetooth earphone/hands-free/bluetooth USB adapter simultaneously, has obviously reduced cost.This device has bluetooth earphone/hand-free function, bluetooth USB adapter and MP3 function simultaneously: also have the dialing/receiving telephone by MP3 except that Music Appreciation with common MP3 and USB flash disk function, carry out wireless data exchange (the synchronous cell-phone telephone book of MP3 etc.) with mobile phone, and the wireless mutual biography of picture, analogue simulation, information between the wireless Internet access, mobile phone and the computer that have as bluetooth USB adapter pass, set up micro radio local area network (LAN) or the like function mutually.Some advantages that also have both the three simultaneously, as: need not that complex drive mechanism, volume are little, easy to carry, easy to use, one-machine-multi-function etc.
Description of drawings
Fig. 1 is the structural representation of an indefiniteness embodiment of the utility model.
Among the figure: 10-USB interface, 11-button, 12-Bluetooth chip, 13-microphone, 14-loud speaker, 15-FlashMemory, 16-LCD display screen, 17-MP3 processor, 18-antenna, 19-commutation circuit.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.In explaining process of the present invention, will omit detailed description to known function and structure.
Referring to Fig. 1, the utility model mainly is made up of usb 10, button 11, Bluetooth chip 12, microphone 13, loud speaker 14, Flash Memory15, LCD display 16, MP3 processor 17, antenna 18, commutation circuit 19.Wherein antenna 18 links to each other by the radio frequency interface of radio frequency line with Bluetooth chip 12, and this antenna can be selected the AT9520 product of Advanced Ceramic X company for use.Usb 10 can link to each other with PC by the USB interface connecting line.MP3 processor 17 also links to each other with LCD display 16 with Flash Memory (flash disk) 15 by address/data bus, and selects by chip selection signal.MP3 processor 17 passes through I
