A speaker cone displayed with one sound wave, intended to represent low or moderate volume. Also often used as an icon to indicate the decreasing of volume on a phone or computer.

Typically depicted as a gray or black loudspeaker viewed at an angle, with a single curved sound wave or ring beside it, though Apple, WhatsApp, and Facebook show the sound wave as a ring overlapping the speaker cone. Microsoft, Twitter/X, Toss Face, and OpenMoji use simplified speaker icons facing directly rightward.

Previously displayed with two sound waves on Android, instead of one. OpenMoji currently displays two sound waves.

Speaker Medium Volume was approved as part of Unicode 6.0 in 2010 under the name "Speaker with One Sound Wave" and added to Emoji 1.0 in 2015.
