    You might not have heard of AAC, but you’ve almost certainly heard from it. AAC is one of the most advanced manufacturers of miniature acoustic components, like the tiny speakers that sit inside iPhone handsets. The ­behind-the-scenes supplier holds over 2,500 patents, not just in acoustics but in haptics (touch-sensing tech), optics, and other miniaturized tech. A trough in the smartphone market this year has pushed AAC’s first-half revenues down 2.5% and its share price even lower, dropping 40% in 2018, but it’s well poised to capitalize on the next up cycle.
