Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in further detail.
Mobile device 101 with intercommunication function provided by the invention, as shown in Figure 1, this mobile device comprises a mobile communcations system 201, this mobile communcations system 201 comprises a communication substrate 202, and a microphone 204 of described communication substrate 202 connection controls and broadcast loudspeaker 205, described mobile communcations system 201 also comprises a battery 203, is used for power supply, these all are the prior aries of mobile device, repeat no more here.
Core setting of the present invention has been wholely set intercommunication control circuit 301 as shown in Figure 2 on described battery 203, and the audio frequency input that described intercommunication control circuit 301 is set links to each other with described microphone 204, and audio frequency is exported and linked to each other with described broadcast loudspeaker 205.Described intercommunication control circuit 301 has separate voice signal processing capacity with described mobile communcations system 201.When described battery 203 is 201 power supplies of described mobile communcations system, also be described intercommunication control circuit 301 power supplies, described intercommunication control circuit 301 is with described mobile communcations system 201 shared described microphones 204 and broadcast loudspeaker 205.
The battery 203 of mobile device of the present invention as shown in Figure 2, it comprises a power brick that is used to discharge and recharge 401, described power brick 401 is set to greater than 1800mAh, stand-by time reaches 30 days, has removed the inconvenience of user's frequent charge from.Be wholely set an intercommunication control circuit 301 on the shell of described power brick 401, described intercommunication control circuit 301 adopts chip design, and its volume is reduced, and can be made of one with described battery 203 on technology is made, and makes the user easy to carry.Described power brick 401 connects described intercommunication control circuit 301, and is described intercommunication control circuit 301 power supplies.Described battery 203 is provided with battery terminal interface 402, and described battery terminal interface connects described power brick 401 and described communication substrate 202, is used for to described mobile communcations system 201 power supplies.Described battery 203 also is provided with state-detection and control interface 403, and described state-detection is connected described intercommunication control circuit 301 and described communication substrate 202 with control interface 403, is used to realize controlling opening or closing of intercommunication control circuit 301.
Described communication substrate 202 is provided with intercommunication operating key PTT key 206, described PTT key 206 is used for realizing the frequency setting of described intercommunication control circuit 301, and control described state-detection and control interface 403, to realize opening or closing of described intercommunication control circuit 301, realize intercommunication function.Described communication substrate 202 is provided with LCD display lamp 207, is used to show the state of intercommunication conversation.The intercommunication frequency configuration of described intercommunication control circuit 301 is a certain characteristic frequency among the 409.7500Mhz-409.9875Mhz, and described frequency is free radio frequency band, can realize by the conversation of described intercommunication control circuit 301 free fully.Described intercommunication control circuit 301 is also by described described microphone 204 of communication substrate 202 controls and broadcast loudspeaker 205, the input and output of audio frequency when being respectively applied for the intercommunication conversation.
When the user uses described mobile device 101 to talk, press described PTT key 206, described state-detection and control interface 403 are opened in control, simultaneously by described microphone 204 input audio frequency, described intercommunication control circuit 301 is handled described audio frequency, and launches with a certain set specific frequency signal among the 409.7500Mhz-409.9875Mhz.When the user uses described mobile device 101 to understand, described intercommunication control circuit 301 receives and handles a certain set specific frequency signal between the 409.7500Mhz-409.9875Mhz, and by described state-detection and control interface 403 with audio transmission to described broadcast loudspeaker 205, realize the obedient function of intercommunication.
