Abstract
A sound generator includes a sound generating body, a base, a protection wall, and an erected wall. The sound generating body includes a diaphragm and a driving portion. The base includes a base tubular portion and a partition wall defining a sound hole. The diaphragm and the partition wall divide an inner space of the base tubular portion into a first space and a second space. The protection wall is disposed away from the partition wall and the erected wall connects between the protection wall and the base tubular portion. The protection wall, the erected wall, and the partition wall defines a sound emission space in communication with the first space through the sound hole. The protection wall and the erected wall define an emission hole through which the sound exits.
