Abstract

The invention discloses a mobile phone capable of being externally connected with an antenna and an identification method. The mobile phone comprises an antenna connection device and a microprocessor controller, wherein the antenna connection device is connected with the microprocessor controller via a circuit. The method comprises the steps of: 1) transmitting a high-frequency analogue signal received by the antenna to an analogue signal processing module through a grounding PIN (pin) of an earphone port; 2) carrying out signal processing on the high-frequency analogue signal by the analogue signal processing module, and 3) analyzing the processed signal by the microprocessor controller so as to judge whether the high-frequency analogue signal received in the step 1) is an antenna signal. The mobile phone has the following advantages that 1, the antenna is pluggable, so the weight of the mobile phone can be reduced, the volume of the mobile phone is reduced and the portability of the mobile phone is increased; 2, the design of an extra mobile phone jack is not needed, not only is the cost saved, but also waste of the design of the mobile phone is avoided.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to the technical field of connecting an external antenna of a mobile phone. Background technique [0002] Along with the development of electronic communication technology, the function of mobile phone is powerful day by day. The function of mobile phones to receive Frequency Modulation (FM, Frequency Modulation) and the function of mobile phones to receive China Mobile Multimedia Broadcasting (CMMB, China Mobile Multimedia Broadcasting) are already common functions of mobile phones. To realize the above functions, it is necessary to set up a FM radio antenna (FM antenna) or a China Mobile Multimedia Broadcast antenna (CMMB antenna) in the circuit of the mobile phone. In the prior art, the (FM antenna) or (CMMB antenna) is built into the main board of the mobile phone. This design not only has poor effect, but also increases the volume of the mobile phone and reduces the adv...
