Embodiment
The utility model is a kind of bluetooth earphone of combined type function, can utilize the bluetooth communication framework to connect various information processor with Bluetooth chip, and with wireless receiving wireless messages (medium signal and speech sound signal), simultaneously also can come the receiving media signal by the various hand-held multimedia device of wired connection, at first please refer to Fig. 1, be the bluetooth earphone configuration diagram of the utility model combined type function.
The bluetooth earphone 1 of the utility model combined type function comprises CPU 10, switch unit 20, Tip element 30, control unit 40, display unit 50, sending and receiving unit 60 and power subsystem 70 simultaneously.Wherein power subsystem 70 is used to provide bluetooth earphone 1 each cell operation required electric power, because the driving power of Bluetooth system generally needs more than the DC 1.8V, so more be provided with a booster circuit in the power subsystem 70 of the present utility model, can directly use commercially available general battery or rechargeable battery (about DC 1.5V is following) the rear drive earphone that boosted, not need to use the battery of special requirement.And sending and receiving unit 60 includes miniature antenna and microphone, can be used for receiving wireless signal, and spread out of the speech sound signal that the user produces, speech sound signal then spreads out of by microphone input back coding again, display unit 50 can utilize light-emitting diode (LED) or LCD (LCD) to design, and the real-time operating state that demonstrates bluetooth earphone 1.
Be connected with CPU 10 as for 40 of control units, this control unit 40 is the working panel of control bluetooth earphone 1, when the playing media signal, can provide that the user plays, various functions such as commentaries on classics soon, selected songs and volume adjustment, when aforesaid various controlling signal produce, then can be sent to CPU 10 carries out, and CPU 10 is except the work of control bluetooth earphone 1, more speech sound signal and wireless signal can be encoded and are deciphered, and in receive by long-range transmit come electric signal the time, send out the prompting signal.
This prompting signal can be divided into inner prompting signal and external prompt signal, the external prompt signal is for when the bluetooth earphone standby is in standby, can point out the user by Tip element 30, this Tip element 30 can be a mini-loud hailer, and when coming the electric signal generation to cause the external prompt signal, send the volume prompting user that warns, display unit 50 also can demonstrate one synchronously and warned and show the effect strengthen prompting this moment, and the user more can be by control unit 40 with this outside prompting signal cancellation or start; Inner prompting signal is then for as user during at use bluetooth earphone 1, can produce an inner prompt tone by CPU 10 and see through switch unit 20 prompting users, switch unit 20 then is available for users to the sound source of switching media signal, and when coming electric signal to produce, select whether to answer long-range incoming call or select refusal to answer.
Next enumerate an embodiment with regard to the switch unit in the utility model and described in detail, please refer to Fig. 2 A, it is switch unit embodiment signal (1) figure of the bluetooth earphone of the utility model combined type function.
The switch unit 20 of the bluetooth earphone of the utility model combined type function is for reaching good handling and switching effect, wherein more include: sound input end 21, sound output 22, first diverter switch 23 and second diverter switch 24, wherein sound output 22 can connect playing device provides the user to listen to wireless signal, suppose that present user is just utilizing Bluetooth wireless transmission to listen to music, sound input end 21 no any signal inputs this moment, L channel L and R channel R are respectively by being sent to first diverter switch 23 after CPU 10 decodings, and be sent to sound output 22 (please refer to dotted line among the figure), 24 of second diverter switches maintain inner earth terminal 10G (with CPU 10 same points) with earth point, with each other impedance between inner each unit of balance, and then keep and well listen to tonequality.
Next please continue with reference to Fig. 2 B, it is switch unit embodiment signal (2) figure of the bluetooth earphone of the utility model combined type function.
(this information processor can be hand-held media player when coming the link information processing unit when the user transports wired connection mode (Line in), personal digital assistant etc.), and come the input medium signal by this sound input end 21, this moment, the user only needed first diverter switch, 23 positions are switched, can find out the connection that first diverter switch 23 has been switched CPU 10, commentaries on classics is provided the stereo music of L channel L and R channel R to sound output 22 (please refer to dotted line among the figure) by sound input end 21, simultaneously because second diverter switch 24 and first diverter switch 23 are synchronization action, so second diverter switch 24 has also changed link position, connect by inner earth terminal 10G and to be changed to external ground end G, with each other impedance between balance bluetooth earphone and external device, and then continue to keep and well listen to tonequality.
Wherein end points in second diverter switch 24 more is provided with a coupling capacitance C simultaneously, when the user uses sound input end 21 that the medium signal is provided, if at this moment long-range have the electric signal of coming to produce, can be directly seeing through CPU 10 is sent to coupling capacitance C and is coupled and produces an inner prompt tone, and after being sent to first diverter switch 23, second diverter switch 24 sends the user to by sound output 22, allow the user in wired connection mode (Line in) when connecting various external device, do not need to interrupt the medium signal that wired connection mode (Linein) is transmitted, can know the generation of all long-range incoming calls too, and can initiatively select whether answer this long-range incoming call or refusal is answered.
Though the utility model discloses as above with aforesaid preferred embodiment; right its is not in order to limit the utility model; anyly have the knack of this skill person; in not breaking away from spirit and scope of the present utility model; when can doing a little change and retouching, therefore protection range of the present utility model should with claim the person of being defined be as the criterion.
