Problems solved by technology

[0006] In the process of realizing the present invention, the inventor found that there are following problems in the prior art: because the frequency of FM / AM signal is low and the wavelength is very long, so that other accessories such as mobile phones with FM transmitter are plugged into chargers or data lines, etc. When using cable equipment, the main frequency signal will radiate out on the cable through ground coupling and space coupling.
As a result, mobile phones or accessories with FM transmitter cannot meet the requirements of safety regulations

Abstract

The invention provides a mobile communication terminal and a method thereof for adjusting the power of an FM / AM (frequency modulation / amplitude modulation) transmitter. The method comprises the following steps: detecting the connection of peripheral devices of the mobile communication terminal to generate the connection information of the peripheral devices; and adjusting the power of the FM / AM transmitter according to the connection information of the peripheral devices. The invention has the following beneficial effects: the technical means that the power of the FM / AM transmitter is adjusted during the connection of peripheral devices is adopted, thereby overcoming the problem of the radiation from the peripheral devices in a coupling manner during the connection with the peripheral devices and further achieving the technical effect that a mobile phone or components provided with the FM / AM transmitter can meet the requirements according to the security specification.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a mobile communication terminal and a method for adjusting power of a frequency modulation / amplitude modulation transmitter thereof. Background technique [0002] At present, with the continuous development of digital technology, various digital electronic products are increasingly attracting the attention of users with their powerful functions and fast and convenient operations. [0003] For example, when consumers choose a mobile phone, in addition to paying attention to its personalized and fashionable appearance, the powerful functions and convenient operation of the mobile phone are also an important factor affecting consumers' choice of mobile phones. For example, with the rapid development of FM / AM technology, especially in some remote areas, it is still the main means of communication. The industry regards the integration of FM / AM in mobile phones as one of...
