Speakers are what are needed to talk in campus chat. To get them you need to tap store, and scroll all the way down. They cost 1 extra credit each. Extra credits can be bought with real money by tapping on store, or where your money shows up, then by tapping on the nurse. Then you choose the appropriate amount you want. Also, doing jobs gives you a 2% chance of getting an extra credit per Job. And finally, there is speaker regen. For new players speaker regen has been halted completely. For older players, they get two a day. It has been halted/reduced because of people(mainly sexters) abusing the free speakers.
