The present invention relates to a tag terminal which outputs a sound source by using an electromagnetic field generated at a near field wireless communications frequency, and a method of manufacturing the tag terminal. According to an embodiment of the present invention, the tag terminal may comprise a communications IC chip; a first antenna connected to the communications IC chip; a second antenna configured to induce an AC power by receiving electromagnetic wave generated by mutual induction with a tag recognition terminal; a rectifier circuit configured to change the AC power induced from the second antenna to a DC power; a control unit configured to receive the DC power rectified by the rectifier circuit; a diaphragm configured to vibrate by using the DC power applied from the control unit; and a printed circuit board on which control unit is formed. |
