Is a resonator guitar type of acoustic with metal cones?

Yes, resonator guitars are a type of acoustic guitar that features metal cones, known as resonator cones or spider cones, mounted on the guitar's body. These cones are usually made of metal, such as aluminum, brass, or steel, and they enhance the guitar's sound by amplifying and projecting it.

Resonator guitars were developed in the early 20th century and gained popularity due to their loud and distinctive tone. They are often associated with blues and country music, and have also been used in other genres such as jazz, rock, and folk.
