Abstract

The present invention provides a CMMB antenna, a CMMB earphone antenna, and a mobile terminal, which belong to the field of antennas. The CMMB antenna comprises a plug to be connected to a first earphone socket of the mobile terminal, a wire, and a second earphone socket. The wire comprises an earphone wire, a ground wire, and an antenna body. The earphone wire and the ground wire have one end connected to the plug, and the other end connected to the second earphone socket. The structure of the second earphone socket is the same as the structure of the first earphone socket. A high-rejection low-pass component is connected to the ground wire in series. One end of the antenna body is connected between the high-rejection low-pass component and the plug. The other end of the antenna body is suspended, and the length of the antenna body is between 9 cm and 16 cm. In the embodiments of the present invention, a high-rejection low-pass component is connected to the ground wire, the antenna body is connected between the high-rejection low-pass component and the plug, and the length of the antenna body is set between 9 cm and 16 cm, so that the CMMB signal has the desirable resonance, thus achieving the good reception performance.

Description

technical field [0001] The invention relates to the antenna field, in particular to a CMMB (China Mobile Multimedia Broadcasting, China Mobile Digital Multimedia Broadcasting) antenna, a CMMB earphone antenna and a mobile terminal. Background technique [0002] In the information age where multimedia is increasing day by day, CMMB mobile phone TV has gradually become the standard configuration of mobile terminals. Because users usually watch CMMB TV programs in public places, in order to avoid affecting others when watching CMMB TV programs, they usually use earphones to play sound, so they need to carry earphones with them. At the same time, if you want to watch clear and smooth CMMB TV programs in a static and high-speed mobile environment, you need to use a high-performance CMMB antenna. In order to reduce the size of the mobile terminal, the existing CMMB antenna is usually an external of. In this way, every time the user goes out, in addition to carrying the earphone,...
