Description
Technical field
The utility model relates to the technical field of wireless headset, particularly a kind of bluetooth earphone.
Background technology
Along with the development of science and technology, it is more and more universal to be equipped with microphone on the earphone, and this class usually is applied on intercom, mobile phone, the apparatus such as computer with the earphone of microphone, and the user can send out voice signal when listening to sound.
Particularly be applied in the bluetooth earphone on the portable digital equipment, earphone connects the restriction that can not be subject to build-out when listening to audio-frequency information by bluetooth with portable digital equipment, and volume is little, use and carry convenient.In order to allow the user can on bluetooth earphone, directly carry out the control (for example audio frequency broadcast, time-out, volume adjustment, telephony feature are connected and hung up) of some simple functions to portable digital equipment, need to arrange corresponding function operating key at small and exquisite bluetooth earphone.But little owing to the volume of bluetooth earphone own, as to be convenient for carrying design characteristics arranges a plurality of function operating keys on its surface, is easy to allow the user faulty operation in use occur.And too much function operating key is unfavorable for dwindling the volume of product.
In sum, continue at present that a kind of volume is little, the function operating key is few, be not prone to the bluetooth earphone of faulty operation.
The utility model content
Technical problem to be solved in the utility model is that present employed bluetooth earphone function control button is many, the shortcomings such as faulty operation appear in volume more greatly, easily, redesigns a kind of bluetooth earphone.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Technical disadvantages for existing bluetooth earphone existence, redesign a kind of bluetooth earphone, its structure comprises Bluetooth control module, loudspeaker SPK, Anneta module, key-press module and supply module, and Anneta module connects with the SMA interface of Bluetooth control module, and key-press module connects with Bluetooth control module.Described loudspeaker SPK connects with Bluetooth control module by the power amplifier module, the IN interface of power amplifier connects with the Sperker interface of Bluetooth control module, described supply module is connected successively by usb interface module, charging circuit module and battery and forms, and described supply module connects with the Pow interface of Bluetooth control module by battery; Described key-press module increases switch key SW2, volume down P cock button SW3, multifunction switch button SW4 and resistance R 1, R21, R8, R9 and R10 by switch key SW1, volume and forms; The end of switch key SW1 connects with the VBAT port of Bluetooth control module, and the other end connects with the ON/OFF port of Bluetooth control module by resistance R 21, passes through resistance R 1 and ground connection between the ON/OFF port of resistance R 21 and Bluetooth control module; Volume increases switch key SW2, volume down P cock button SW3 and is connected an end with multifunction switch button SW4 and is connected with the vdd terminal mouth of Bluetooth control module respectively, the other end that volume increases switch key SW2 connects with the VR+ port of Bluetooth control module by resistance R 8, the other end of volume down P cock button SW3 connects with the VR-port of Bluetooth control module by resistance R 9, and the other end of multifunction switch button SW4 connects with the PIO port of Bluetooth control module by resistance R 10.
Being provided with microphone connects with the Mic interface of Bluetooth control module.
Being provided with the charging indicator light module connects with the PowLED interface of charging circuit module.
Being provided with the relay indicating light module connects with the WorkLED interface of Bluetooth control module.
Described key-press module is a multifunction switch button SW4 control circuit commonly used.
The realization of individual palpation function, Bluetooth control module provide PIO to detect button.When individual palpation multifunction switch button SW4, the PIO mouth is drawn as high level, and this time, Bluetooth control module detected PIO high level, writing time.After reaching 500mS, PIO mouth step-down, and surpass 500mS and do not uprise, be the individual palpation of button.
Two keypress functions, when pressing multifunction switch button SW4, the PIO mouth is drawn as high level, and this time, Bluetooth control module detected PIO high level, writing time.After reaching 500mS, unclamp button, PIO mouth step-down is pressed multifunction switch button SW4 again in 500mS, PIO is drawn high again, after reaching 500mS, again unclamps button, and the PIO mouth is step-down again, and surpass 500mS, the PIO mouth does not uprise again, realizes keypress function this moment two times.
Three keypress functions, when pressing multifunction switch button SW4, the PIO mouth is drawn as high level, and this time, Bluetooth control module detected PIO high level, writing time.After reaching 500mS, unclamp button, PIO mouth step-down, press multifunction switch button SW4 in 500mS, PIO is drawn high again, after reaching 500mS again, again unclamp button, the PIO mouth is step-down again, presses for the third time multifunction switch button SW4 in 500mS, PIO is drawn high again, after reaching 500mS, again unclamps button, the PIO mouth is step-down again, and surpass 500mS, the PIO mouth does not uprise again, realizes keypress function this moment three pairs times.
After these three keypress functions are realized, can correspond to different keypress functions, can realize receiving calls such as individual palpation, on-hook, two times button can be realized a song, three times button is realized the functions such as next song.
The utility model is compared with prior art, and its beneficial effect is:
Reduce the quantity of function operating key, greatly dwindle the volume of bluetooth earphone.Reduce the probability of user error operation.
