Soberton audio exciters are used and driven like a speaker but make their audio by turning the object they are mounted to into sound generating devices. Exciters offer a water and dustproof solution for robust applications where speakers cannot perform. This also allows engineers to place audio anywhere without mounting holes. They are currently offered in 8 ohms, and in sizes ranging from 18 mm to 44 mm and 2 watts to 5 watts rated power. Exciters also produce sound at a wider angle allowing sound to disperse more than a standard speaker.
