a speaker enclosure including an upper surface, a lower surface and a side surface connecting the upper and lower surfaces;
a diaphragm disposed in an inner accommodating space of the speaker enclosure and configured to generate sound waves by vibrating according to an electrical signal;
a first phase plug spaced apart from the diaphragm; and
a second phase plug spaced apart from the first phase plug and forming a guide path to guide the generated sound waves from the diaphragm to be emitted omnidirectionally from the side surface of the speaker enclosure,
wherein a width of the guide path formed by the first phase plug and the second phase plug increases towards the side surface of the speaker enclosure.
