Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.The bluetooth earphone that mobile phone of the present utility model is used comprises two parts: hardware is realized and software is realized.As shown in Figure 1, hardware of the present utility model has bluetooth module (BLUETOOTH MODULE), bluetooth module is connected with organic light emitting display (OLED), keyboard (KEYBAOR), memory (as flash memories FLASH) and antenna (ANT), also promising bluetooth module power supply and the external power supply (POWER) of accepting charging.
Bluetooth module comprises Bluetooth chip, crystal oscillator etc., it is the carrier of bluetooth software, realize the function of various bluetooths, organic light emitting display is used for display graphics and character, obtains the numeral that button is pressed on the keyboard, storage and visit flash memories, antenna and mobile phone handsets wireless connections, flash memories is used to store data, can be read and write data, and keyboard is with the input terminal key number.
Operation principle of the present utility model is: bluetooth module can be set up with other bluetooth equipment and connect intercommunication mutually, comprised transmission Bluetooth stereo audio frequency standard (A2DP), bluetooth player control standard (AVRCP), bluetooth hands (HFP), bluetooth earphone standard (HSP) and telephone directory access customer standard (PBAPC) Bluetooth specification, set up mutually by these standards and other bluetooth equipment and to connect and communicate by letter, then the various states of bluetooth or information are demonstrated suitable figure and character on organic light emitting display, perhaps storage, the data of visit on flash memories.By at the enterprising line operate of keyboard, bluetooth module can obtain the key value of terminal, and bluetooth module carries out function corresponding again and realizes then, realizing the requirement of terminal, and the result is handled accordingly, is presented on the organic light emitting display.
Organic light emitting display dot matrix screen is adopted in display part of the present utility model, usually graphic dot matrix that will show or character library dot array data is stored in the internal storage space of Bluetooth chip, perhaps is stored in the plug-in memory.When wanting display graphics or character, if the dot array data that shows is stored in the Bluetooth chip, Bluetooth chip outputs to dot array data on the organic light emitting display to data by certain form by I2C (Inter-IC) interface, just can be at corresponding position display figure or character; If be stored in plug-in memory, Bluetooth chip reads the dot array data that will show by the I2C interface earlier, outputs on the organic light emitting display wanting data presented to write by the I2C interface then, just can be at corresponding position display figure or character.Caller identification of the present utility model, at first bluetooth earphone and mobile phone connect, the using standard of bluetooth earphone is HFP, the using standard of bluetooth cellular phone is voice gateways (AG), then bluetooth earphone send some mobile phone transmission data forms instruction (AT:Attention) to bluetooth cellular phone, in the time of call, the call number on the mobile phone will be transferred on the Bluetooth chip of bluetooth earphone, Bluetooth chip is converted into corresponding dot array data to telephone number, then dot array data is passed through I
2C is transferred to OLED and is presented on the corresponding position.
Memory device of the present utility model is band I
2The memory of C interface, Bluetooth chip passes through I
2C interface is write memory to data according to certain form, and perhaps Bluetooth chip passes through I
2C interface according to certain form from memory reading of data to Bluetooth chip.In the process of storing call, at first connect with mobile phone, what this bluetooth that connects mobile phone was used is telephone directory access services standard (PBAPS), bluetooth earphone is a telephone directory access client standard (PBAPC).By this connection, bluetooth earphone can access the phone directory of mobile phone end, telephone number on the mobile phone will be being transferred on the bluetooth earphone of next rule of control of bluetooth earphone end, and store the telephone number that is transferred to bluetooth earphone into hold function that memory has just been finished phone directory this time.Same principle, the utility model can be preserved the telephone number of having transferred to and the telephone number of not answering, and reads these data then and is presented on the OLED screen, also can read telephone number in the memory and be presented on the OLED screen and call then.
Keyboard of the present utility model is a Macintosh, use six general input and output (IO) mouth of Bluetooth chip to be combined into 14 buttons altogether, comprise that 0-9 digital keys, ON/OFF (ON/OFF) button, function of tonic chord key (LCAL) button, volume add (UP) button and volume down (DOWN) button.When button is pressed, these six universal I/O ports will have two universal I to put high level, and Bluetooth chip response universal I level changes then, obtain this two high level IO corresponding key values, if at dial-up operation, Bluetooth chip will be converted into dot array data to the key value that obtains, and pass through I then
2C is transferred to OLED to dot array data and shows dialed digit on the position of correspondence.
Power supply of the present utility model comprises LTC4054 and RT9167 chip, and LTC4054 is charging chip IC, is used for managing battery charge.In the time of battery charge, the output of the charging of LTC4054 indication pin low level, Bluetooth chip obtains the charged state indication; When being full of or do not charge, the output of the charging of LTC4054 indication pin high level, Bluetooth chip obtains non-charged state indication.RT9167 is a power management chip, and 3.3V and 2.7V output is arranged respectively, the power supply of control Bluetooth chip, OLED, FLASH.When the CE of RT9167 pin was high level, the VOUT of RT9167 was that 3.3V gives Bluetooth chip and OLED power supply, and when the CE pin was low level, the VOUT of RT9167 was 0V, stopped to Bluetooth chip and OLED power supply.
As shown in Figure 2, Bluetooth chip connects microphone, loudspeaker, memory, OLED screen, keyboard circuit, charging IC circuit, electric power management circuit and antenna, and battery is connected with electric power management circuit through the DC-DC translation circuit.Receiver when microphone is telephone relation, 8k sampled speech data are packaged into suitable data format in Bluetooth chip, have data antenna transmission to go out then.Receiver when loudspeaker are telephone relation, voice are received by Bluetooth antenna, in Bluetooth chip VoP are reverted to speech data then, and after the digital-to-analogue conversion, the other side's sound has just been heard in output on loudspeaker.The displaying principle of OLED screen is that Bluetooth chip passes through I
2The control command of C transmission OLED screen or dot array data just can be at corresponding position display figure or characters to OLED.
As shown in Figure 3, the software model for the utility model uses comprises Bluetooth protocol, driving and application program etc.Bluetooth protocol comprises that these five of A2DP, AVRCP, HFP, HSP and PBAPC use section.A2DP is a transmission Bluetooth stereo audio frequency standard, the transmission stereo audio, AVRCP is a bluetooth player control standard, can the broadcast of controls playing device, time-out etc., HFP is a bluetooth hands, HSP is the bluetooth earphone standard, and PBAPC is a telephone directory access client standard, can obtain phone directory from mobile phone.Driving comprises that OLED screen, KEYBOARD and FLASH drive.The OLED screen drives the functions such as initialization, display graphics or character of finishing screen, and KEY BOARD finishes in terminal input key number, and FLASH drives and comprises visit and write data, finishes the storage and the visit of data.
As shown in Figure 4, as most preferred embodiment, bluetooth module of the present utility model adopts the CC_BC03EXT_1_V10 of Chuangcheng Digital Technology Co., Ltd., display screen adopts the S0102QKPC-C of Taiwan Qijing Photoelectric Co., Ltd., memory adopts the AT24C512 of Atmel company, and wherein Bluetooth chip adopts the BC352239A of CSR company.
