Maryam Landi Develops New Miniature Speaker Structure for Enhanced Sound

Maryam Landi, a recent graduate of The University of Mississippi’s Master of Science physics program, was featured in the Graduate school Summer 2018 newsletter for developing  a new structure that emits sound waves from miniature speakers more efficiently, especially when it comes to low frequency, or bass. A lot of speaker designs in the world yield powerful, high-quality sound but fail to deliver when the speaker is miniaturized. This is because no one has figured out the physics behind doing so — until now. The article describes her physical acoustics research with Dr Likun Zhang and others on metacavities that act as highly effective miniaturized speakers. Their work was published in Physical Review Letters (Phys. Rev. Lett. 120, 114301).
