[0027] The following is a detailed description of the working principle of the mobile phone case 100 provided by this utility model for configuring PTT public network intercom function for mobile phone terminal 200.

[0028] When the PTT public network intercom function needs to be used through the mobile terminal 200, first connect the mobile phone case 100 used to configure the PTT public network intercom function of the mobile terminal 200 to the mobile terminal 200, that is, put the case on the mobile terminal 200. Then operate the toggle switch 231 to establish a communication connection between the control unit 222 and the data exchange unit 221. At the same time, the switch circuit 23 will also send a signal to the mobile terminal 200 through the data exchange unit 221. After receiving this signal, the mobile terminal 200 will enter the host mode. The PTT module 2 acts as a slave module of the mobile terminal 200. The mobile terminal 200 supplies power to the PTT module 2. At this time, the data transmission of the first connection unit 10 is temporarily handed over to the control unit 222 for management by the mobile terminal 200. Then press the key 211 of the PTT button circuit 21 to trigger the intercom signal. After the control unit 222 detects the intercom signal, it will convert the intercom signal into a key value and transmit the key value to the mobile terminal 200. The PTT software on the mobile terminal 200 will start, and the operator can start intercom or listen. When the PTT public network intercom function is not needed, operate the toggle switch 231 to disconnect the communication connection between the control unit 222 and the data exchange unit 221, and make the first connection unit 10 and the first connection socket 3 conduct. At this time, the mobile terminal 200 can be charged by the power adapter or connected to the computer by the data cable to transmit data.

[0029] Compared with the prior art, the mobile phone case 100 provided by this utility model for configuring PTT public network intercom function for mobile phone terminal 200 sets up PTT module 2 in the case 1, and connects PTT module 2 to mobile phone terminal 200 through first connection unit 10 to enable data transmission between PTT module 2 and mobile phone terminal 200. PTT module 2 includes PTT button circuit 21 and intercom control circuit 22 electrically connected to PTT button circuit 21. Through PTT button circuit 21 and intercom control circuit 22, mobile phone terminal 200 can enter PTT public network intercom mode. At this time, mobile phone terminal 200 supplies power to PTT module 2, and PTT module 2 becomes a subordinate module controlled by mobile phone terminal 200. Therefore, the phone case 100 provided by this utility model for configuring PTT public network intercom function on a mobile terminal 200 can both enable PTT public network intercom with the mobile terminal 200 and retain the functions of the mobile terminal 200, eliminating the need to carry additional PTT public network intercom equipment. Furthermore, the phone case 100 can fit snugly against the mobile terminal 200, thus greatly saving carrying space and improving ease of use. In addition, controlling the PTT module 2 through the mobile terminal 200 makes operation more intelligent, enriches the intercom functions, and provides a better user experience.
