Not in the Catholic dictionary. Not in the New Advent Catholic encyclopedia. Tells you something.
From what I could glean without clicking on anything it is a steeple sort of thing with a balcony on which someone can stand and call people to prayer.
*Why not just ring the bells like Catholics do?” My question — LOL!
Actually that is a good question. Not necessarily regarding bells, but is there a cultural or religious prohibition to something like this in Islam like there is regarding artistic depictions (which led to the unique artistic styles on classical Islamic architecture)? Bells or horns could be more efficient and certainly wouldn't be unknown.
