Megaphone

The Megaphone is a Hardmode accessory that can be obtained by killing Pixies, Green Jellyfish, Dark Mummies, or Blood Mummies with a 1% / (1/100 / ) chance. When equipped, it grants immunity to any Silenced debuffs.

It is one of the ingredients required to make the Countercurse Mantra, which is a crafting material required to make the Ankh Charm, an accessory further required to make the Ankh Shield.

Trivia

 * Despite its purpose to grant immunity to the Silenced debuff, it would seem to be rather ineffective at its purpose for silence would normally take away the user's voice completely. So theoretically for this item to work, being Silenced would have to mean having your voice lowered to a point but not completely muted.
 * The fact that the megaphone is a drop from the pixie is a reference to how the fairies in the Legend of Zelda series which look similar to the pixies are known to be loud and often annoying.
