US 2019/0172439 A1 · Sound Emitting Device

Abstract

A sound making device and system for generating white noise is disclosed. The sound making device generally includes a substantially dome-shaped device that includes an outer acoustic shell and an inner acoustic shell mounted atop a base tray. Both the outer acoustic shell and inner acoustic shell have slots (or openings) that overlap to create apertures through which rushing air can pass. The amount of slot overlap is variable. Further, a variable speed fan is arranged inside the outer acoustic shell and inner acoustic shell for forcing airflow out of the apertures. The sound making device also includes a controller and user interface for adjusting the speed of the fan. Further, a sound making system is provided that includes the sound making device in combination with a mobile app.
