The wireless bluetooth sound box is characterized in that the main control module, the bluetooth module, the audio frequency amplification module, and the sound box are connected in order, and that the main control module is connected to the display module and the button module respectively. The button module is used for inputting control signals; the display module is used for displaying communication data so that system operations are convenient; the main control module is used for controlling operations of the system, receiving the command signals of the button module, and transmitting the signals to the bluetooth module; and the bluetooth module is used for connecting external bluetooth terminals (mobile phones or PC computers), and controlling the terminals to realize functions including playing music or dialing by transmitting commands.
Description
Technical field
The utility model relates to a kind of audio amplifier, especially the blue teeth wireless audio amplifier.
Background technology
Bluetooth is a kind of radiotechnics of support equipment short haul connection, can comprise that carrying out wireless messages between numerous equipment such as mobile phone, PDA, wireless headset, notebook computer, relative peripheral exchanges.Utilize Bluetooth technology, can simplify the communication between the mobile communication terminal device effectively, make transfer of data become efficient more rapidly.
Summary of the invention
In view of above these situation, the utility model provides a kind of blue teeth wireless audio amplifier.With the single-chip microcomputer is the master control module; Adopt the wireless blue tooth technology, supported point-to-point and point-to-multipoint delivery, be operated in 2.4GHz ISM (i.e. industry, science, the medical science) frequency range of global general-use; Adopt the time division duplex transmission plan to realize full duplex transmission, data rate is 1Mb/s.
The utility model provides a kind of blue teeth wireless audio amplifier; Comprise bluetooth module, audio frequency amplification module, audio amplifier, master control module, display module, key-press module; It is characterized in that: master control module, bluetooth module, audio frequency amplification module, audio amplifier connect successively, and the master control module also is connected with display module, key-press module respectively.Key-press module is used for input control signal; Data make things convenient for system operation thereby display module is used for display communication; The master control module is used for the running of control system, and the command signal that receives key-press module also is transferred to bluetooth module, and bluetooth module is to be used for connecting outside Bluetooth terminal (mobile phone or PC computer); And realize playing back music through the terminal of sending its connection of order control, function such as call.
The beneficial effect of the utility model is, adopted the wireless blue tooth technology, and the flexibility that has improved equipment has higher utility, economic worth.
Description of drawings
Fig. 1 is the theory diagram of the utility model.
Embodiment
In Fig. 1; The utility model provides a kind of blue teeth wireless audio amplifier; Comprise bluetooth module 1, audio frequency amplification module 2, audio amplifier 3, master control module 4, display module 5, key-press module 6; It is characterized in that: master control module 4, bluetooth module 1, audio frequency amplification module 2, audio amplifier 3 connect successively, and master control module 4 also is connected with display module 5, key-press module 6 respectively.Key-press module 6 is used for input control signal; Thereby display module 5 is used for the display communication data makes things convenient for system operation; Master control module 4 is used for the running of control system, and the command signal that receives key-press module 6 also is transferred to bluetooth module 1, and bluetooth module 1 is to be used for connecting outside Bluetooth terminal (mobile phone or PC computer); And realize playing back music through the terminal of sending its connection of order control, function such as call.
What master control module 4 adopted is the C8051F020 single-chip microcomputer, and wherein UART0 is configured in P0.0 (TXD) and the P0.1 (RXD) of C8051F020, is connected with bluetooth module 1 serial ports through serial connection 1k Ω resistance.Bluetooth module 1 is deferred to bluetooth 1.1 standards, is the communication module of a point-to-multipoint.This module can be simultaneously and in its scope connected 7 bluetooth slave units realize transfer of data.The effective radius of Bluetooth communication is relevant with the power of its output: when power output was 2.5mW/4dB, communication range was 15m; Because C8051F020 and bluetooth module are the 3.3V system, so need not increase extra level conversion serial communication circuit, have simplified system design.The order and the data of the port P3 control display module 5 of C8051F020 show that port P2 accomplishes the input of key-press module 6.Matrix keyboard is mainly used by C8051F020 in key-press module 6 importations, and it is few to have the I/O of taking resource, and I/O port P2 gating matrix formula 4 * 5 keyboards are accomplished.SHIFT is the function switching key, between HFP and A2DP, switches.Button 0～3 is a multifunction push key, when the SHIFT key is not pressed, the expression digital keys called 0～3 or incoming call answering, hang up the telephone, refusing incoming call and re-dialing function; When the SHIFT key is pressed, represent music time-out/beginning, connection bluetooth music, next song and last one bent function successively.Button D, E, F and G press no effect for system's reserved function expansion button.For bluetooth module 1 voice signal importation; Accomplish the input of voice signal through electret microphone; The audio signal output of bluetooth module 1 then passes through TDA2030A to drive load; Amplify through audio frequency amplification module 2 then, that audio frequency amplification module 2 adopts is the audio-frequency power amplifier TDA2030A of CONTEK company, constitutes OCL and connects method; Peak power output can reach 14 W, and audio signal SPKR+ and SPKL+ get into two TDA2030A respectively and carry out power amplification to drive the audio amplifier 3 of RL=4 Ω.
