Magical megaphone

A magical megaphone is similar to a Muggle megaphone, however, it is bewitched to amplify the user's voice much more than the Muggle version.

It is popularly used to commentate on Quidditch matches in Hogwarts, however, it is presumably used in other sports. It is possible that the megaphone has been bewitched with the Sonorus charm, however it is unknown whether the charm can be cast on an object.

c. 1991-1994
Lee Jordan used the megaphone to commentate on the Quidditch matches being played.

In 1993, Minerva McGonagall announced that the final match of the season would be cancelled using a similar, purple megaphone, possibly the same one.

1995-1996
Lee Jordan continued to commentate on the Quidditch matches being played using the megaphone during his final year at Hogwarts.

1996-1997
Zacharias Smith, Jordan's successor, took over his commentating duties once Jordan had left.

As Smith could not attend one of the matches, Luna Lovegood took over instead.
