<p>An NFC communication module is applied to the field of radio-frequency communications, and comprises an NFC circuit with an antenna connection point and a loudspeaker with a coil. The access point of the coil is connected to the antenna connection point of the NFC circuit. The loudspeaker coil is simultaneously used as an NFC antenna, thereby being able to make the NFC communication module have a smaller antenna area. There is no need to independently set an antenna (coil), thereby having lower manufacturing costs.</p> |
