Abstract

The invention discloses a mobile terminal, which comprises an antenna, a headphone socket and a high frequency filter circuit. The headphone socket comprises a headphone jack and a suspended microphone pin arranged in the headphone jack. The high frequency filter circuit is arranged in series between the suspended microphone pin and the ground. The antenna is disposed near the suspended microphonepin. The high frequency filter circuit is used for filtering out an antenna signal received by the suspended microphone pin, and the positional relationship between the antenna and the headphone socket can be arbitrarily set, and in this way, the problems that the position setting of the headphone socket and the antenna is difficult, when the distance is too small, the headphone socket affects the signal reception of a three-in-one antenna, a headphone suspended metal and the antenna is caused to couple, and the performance of the three-in-one antenna decreases as a result, or, when the distance is too large, the layout of a mobile phone PCB is not facilitated.

Description

technical field [0001] The present invention relates to the technical field of mobile electronic equipment, in particular to a mobile terminal. Background technique [0002] At present, in the ID (appearance) design of mobile phones, the earphone holder is mostly set on the top of the mobile phone case, and the three-in-one antenna is distributed in the right area of ​​the earphone holder, and the left area can be equipped with a diversity antenna that requires a large area. The distance between the earphone holder and the 3-in-1 antenna must be set appropriately. If it is too small, the metal part inside the earphone holder will inevitably affect the signal reception of the 3-in-1 antenna, resulting in a decline in the performance of the 3-in-1 antenna. If it is too large, it will be detrimental to the mobile phone PCB. board layout. Contents of the invention [0003] The main purpose of the present invention is to provide a mobile terminal, aiming to solve the problem o...
