Right Speaker with One Sound Wave refers to an audio-control symbol concept depicting a speaker aimed to the right with a single curved sound wave, suggesting low or medium volume. It was discussed in the broader context of Unicode pictographic symbols and emoji-style candidates from the era when many interface icons, Webdings-like symbols, and phone UI concepts were being evaluated for emoji compatibility. Although similar speaker emojis became familiar through characters such as 🔉 Speaker Medium Volume, this specific right-facing form did not become a commonly supported, officially RGI emoji on modern platforms.
