Embodiment 1

[0021] figure 1 Shown is the flowchart of the FM / AM transmitter power adjustment method of the mobile communication terminal in Embodiment 1 of the present invention, as figure 1 shown, including:

[0022] S101: Detect the connection status of peripheral devices of the mobile communication terminal, and generate peripheral device connection information;

[0023] S102: Adjust the frequency modulation / amplitude modulation transmitter power of the mobile communication terminal according to the peripheral device connection information.

[0024] Wherein, the peripheral device includes a charging device and a data line.

[0025] In Embodiment 1, by adjusting the power of the FM / AM transmitter according to the connection of the peripheral equipment, it overcomes the problem that the main frequency signal radiates out on the peripheral equipment through coupling when the peripheral equipment is connected, so that the transmitter with the FM / AM transmitter The mobile phone or access...

Embodiment 2

[0027] figure 2 What is shown is a schematic structural diagram of a mobile communication terminal according to Embodiment 2 of the present invention. The mobile communication terminal according to Embodiment 2 of the present invention includes: a detection unit 201, configured to detect the peripheral device connection status of the mobile communication terminal, and generate a peripheral device connection status. Information; a power adjustment unit 202, configured to adjust the frequency modulation / amplitude modulation transmitter power of the mobile communication terminal according to the peripheral device connection information. Wherein, the peripheral device includes a charging device and a data line.

[0028] Through the second embodiment, since the power of the FM / AM transmitter in the mobile communication terminal can be adjusted correspondingly according to the connection status of the peripheral equipment, the mobile communication terminal can meet the requirements...

Embodiment 3

[0030] image 3 Shown is the structural representation of the mobile phone of the embodiment of the present invention, as image 3 Shown, the mobile phone of embodiment comprises: radio frequency unit, baseband circuit, speech decoding / encoding unit, D / A, A / D unit, keyboard, FLASH unit, RAM unit, SIM unit, LCD display unit, CPU, and Also includes: FM / AM transmitter 301, used to transmit radio broadcasts for communication; detection unit 302, used to detect the connection of peripheral devices of the mobile communication terminal, and generate peripheral device connection information; power adjustment unit 303, used for Controlling the frequency modulation / amplitude modulation transmitter power of the mobile communication terminal according to the peripheral device connection information. Wherein, the peripheral device includes a charging device and a data line.

[0031] Through the third embodiment, since the mobile phone can adjust the power of its FM / AM transmitter corresp...
