Not with the loudspeaker itself, no. Just click on it for info/April's comment. What have you managed to do so far? Has April shouted to/woken Q'aman yet? Have you used the statue key on all of the statues?
Use the statue key on the statues. Then click on the left arrow to move the top wheel and the right arrow to move the bottom wheel. Take the key after the correct icons are placed.
Large trees statues: Top wheel to send to cliff. Bottom wheel to receive from itself - tall trees.
Cliff statue: Top wheel to send to ruin. Bottom wheel to receive from large trees.
Old city statue: Top wheel to send to volcano. Bottom wheel to receive from cliff.
Use the mouth icon on the tall trees statue's 'ears'.
