In addition to the use of the city bus radio track to enjoy the information, you can also use the handheld device to make the earphones of the new earphones more powerful. The Bluetooth headset has a wired connection (Li This (8), when the action ΐΖΠ call signal scale, blue material machine _ electronic switch will be strong cut off the existing use of wired connection (Une (5) transmitted media message ^ user answer the mobile phone device call signal, etc. Disk mobile communication equipment (4) tearing money, m彳_输娜^(5) When it is not convenient. The transmission of Lai, but such a wealthy style will make the Langer not independent, but must answer every communication of the mobile communication device In response to the call signal, the author also proposes a composite function of the Bluetooth headset, the purpose of which is to improve the shortcomings of the conventional technology, so that the user can choose to listen to the action. The signal 'This blue machine includes the function of wireless transmission of Bluetooth, and also includes the function of using the wired connection (Llne ιη ice to receive the media signal of the stereo sound), so that everyone can be free _ want _ blue bud scale Transmitted to receive media signals, or connected to other financial devices to receive M288074. A physical number 'on the same day, when the incoming call signal is generated, an internal prompt tone will be generated first, so that the user can choose whether to answer the incoming call signal. Another purpose of the same creation is to remind the user to call in the standby mode. If the bud headset receives a call signal during standby, the Bluetooth headset can also generate an external tone to remind the user. It will be more convenient to use. The details of this creation are as follows: [Embodiment] This creation is a kind of composite Weizhi blue material machine, which can be used to communicate with the communication system. Connect various types of information processing devices with age u, and wirelessly receive wireless information (media signals and voice signals), and also connect various handheld multimedia devices by wired connection. To receive media signals, please refer to the "Dimensional Map" for the first time. This is a schematic diagram of the architecture of the composite Bluetooth headset. The composite function reader of this creation, including the towel processing unit 10, switching unit 20. The prompting unit 30, the control unit 40, the display unit 5〇, the receiving unit (9) and the power supply unit 70, and the financial power unit (4) provide the required power for the Bluetooth headset 1 respectively, due to the driving power of the Bluetooth system. Generally, it is necessary to sink more than W. Therefore, the power supply unit 7G _ er-system of this creation can directly use the commercially available battery or charge Wei (about 5V or less) to drive the headphones, not please The secret, _ yuan contains a micro-antenna and microphone, can be used to receive wireless signals, and the 5 mega-signal generated by the user, and the voice signal is encoded by the microphone and then transmitted, the M288074 unit The 50 can be designed using the light emitting diode (10) or the liquid crystal display (10), and the operating state of the Bluetooth headset 1 is displayed. - As for the control unit 40, it is connected to the central processing unit 1〇, and the control unit 4 is a panel for controlling the monitor 1 and a miscellaneous ship scale, which can provide users, play, fast turn, music selection and volume adjustment. When various functions are generated, they will be sent to the central processing material H) for execution, and the central processing will be 7010 in addition to controlling the work of the Bluetooth headset J, and the voice signal and wireless Lu can be used. The signal is encoded and decoded, and when the incoming call signal from the far end is received, a prompt signal is transmitted. ... This prompt can be divided into (4) prompt gift u and external prompt subtraction, the external prompt signal is when the blue earphone standby is in standby, the prompting unit 30 can prompt to make the sound, the prompting unit 30 can be - micro expansion When the (4) signal generates an external prompt signal, the alarm sound is emitted to alert the user. At this time, the display unit 50 can also display a warning display to enhance the reminder function, and the user can control the alarm. As early as 4G to cancel or start this external prompt signal; the internal prompt signal is when the user is using Bluetooth headset! When the central processing unit i 〇 generates an internal prompt tone to remind the user through the switching unit 2 而, and the switching unit 2 〇 can be used as a user _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Remote call or choose to reject the call. ‘ ^The following is a description of the cut towel. The example is a detailed description of the example. The pure "2A ®" is the switching unit of the blue-type machine for creating a composite function. M288074 The switching unit 2G of this creative composite Weizhi blue machine rides into a good handling and switching effect', which further includes: sound input terminal 21, sound wheel output terminal 22, first-switching switch 23 and second switching switch 24, wherein the sound output terminal 22 can be connected to the playing device to provide the user to listen to the wireless signal. It is assumed that the user is currently listening to the music by using the Bluetooth wireless transmission. At this time, the sound input terminal 21 has no signal input, and the channel L and the right are The channel R is decoded by the central processing unit 1 () and transmitted to the first switch «23, and the f^off 24 is maintained at the ground end 1〇G (same as the central processing unit w). 'With the impedance of each unit in the flat survey department, the sound quality is improved. Next, please continue to refer to "2B", which is a schematic diagram (2) of the switching unit of the Bluetooth headset for creating a composite function. When the user connects to the line processing device (Line in) to connect to the f-processing device (this poor processing device can be a handheld media player, a personal digital assistant, etc.), and thus the voice person 21 _ person Ship gift, at this time to make the switch to switch, you can see that the first - switch open (four) has switched the central ... 70 connection 'turned to the sound input terminal 21 to provide left channel L and right 敕 R to the stereo music to The sound output end 22 (please refer to the dotted line in the figure), and at the same time, because the change switch 24 and the first change switch 23 are synchronized, the second switch is open and the balance is (4) touched, and (4) the object touches the external ground terminal G, The yarn stands for the mutual impedance between the earphone and the external device, and continues to maintain a good 'synthesis capacitance. At the same time, in the second field, the bud is more equipped with the M288074 C. Although the user uses the voice input terminal 21 to provide the media. In the signal, if there is an incoming call signal generated at the remote end, it can be directly transmitted to the wheel motor through the central processing unit 1 to generate an internal prompt tone, and transmitted to the second through the second cut lake switch 24 - switching switch 23 is transmitted to the gambler by sound output terminal 22, When the user connects the external devices in the wired connection mode, it is not necessary to interrupt the media signal transmitted by the wired connection (Line in), and the same can also be known for the generation of all remote calls. Choose whether to answer this far-end call or Du although the creation of the fine-grained health #_ exposes the above, and it is limited to the creation of the 'any lion', in the spirit and scope of the masterpiece, when you can make a little The __, therefore, the protection of this _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ [Simple description of the figure] The first picture is a schematic diagram of the material-based earphones of the creation of the composite function; the second picture is the blue-and-white η _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The figure is a schematic diagram of the switching of the blue-buds of the creative composite function (2).
