Making schoolwide announcements
These loudspeakers were used in Hogwarts School of Witchcraft and Wizardry to make schoolwide announcements. In the 1992–1993 school year some loudspeakers were used to bring the news during the plot about the Chamber of Secrets. During the 1995–1996 school year, when Dolores Umbridge, Defence Against the Dark Arts teacher, temporarily assumed the position of Headmistress, she used these speakers to announce her restrictive policies. Dumbledore's Army members Padma Patil, Parvati Patil, and Harry Potter responded by sabotaging the speakers with Babbling Beverage, so they would spout nonsense instead.
