Be noted that the description and the following detailed description all are exemplary, being intended to provides further instruction to desired the utility model.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.Below with reference to figure, other purpose, feature and effect of the present utility model is described in further detail.
Description of drawings
Constitute this specification a part, be used for further understanding and of the present utility modelly illustrate preferred embodiment and be used for illustrating principle of the present utility model with explanation.Among the figure:
Fig. 1 is the module diagram according to the wireless headset based on WLAN of the present utility model;
Fig. 2 shows the module diagram of the system that is made up of portable terminal and wireless headset.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment the wireless headset based on WLAN of the present utility model is described in detail.
Fig. 1 is the module diagram according to the wireless headset based on WLAN of the present utility model.As shown in Figure 1, comprise WLAN module 101, WLAN protocol module 102, other peripheral hardware (supplementary module) 103 according to wireless headset of the present utility model; Audio decoder 104 and receiver 105.
Wherein, WLAN module 101 is when being used to send, and the speech data that will come from WLAN protocol module 102 changes into analog signal, sends after again analog signal being upconverted to 2.4GHZ.WLAN module 101 is down-converted to analog baseband signal with the 2.4GHZ radiofrequency signal that receives and transfers to the baseband processor digitlization when being used to receive, again by WLAN protocol module 102 control MAC agreement flow processs.
WLAN protocol module 102 is responsible for earphone and is set up control, access control being connected of main equipment and finish the processing that the control of MAC agreement is reached call flow when communicating by letter.The WLAN protocol module is realized the MAC access mechanism of the 802.11b of standard.IEEE802.11 WLAN standard can be known from network.In addition, WLAN protocol module 102 also is responsible for the transfer of data that scheduling receives, sends WLAN module 101 and audio decoder 104.
Other peripheral hardware 103 links to each other with WLAN protocol module 102, comprises power module, key-press module and connects, disconnects indication.
Fig. 2 shows the module diagram of the system that is made up of portable terminal and wireless headset.As shown in Figure 2, cooperatively interacting with wireless headset has additional WLAN module 201 and mode switch module 202 in the portable terminal that uses, and wherein WLAN module 201 is finished and WLAN module 101 identical functions; For compatible bluetooth module 203, mode switch module 202 is mainly used in the selection of EM equipment module, as output module, and speech data that will be to be exported switches on the output module (being WLAN module 201 or bluetooth module 203) of its selection with WLAN module 201 or bluetooth module 203 in selection.
