Abstract
A partition system with a speaker includes a plurality of wall surfaces configuring an acoustic blocker that is partially open and partially blocked, in a plan view, and having a first wall surface and a second wall surface, and a directional speaker disposed on the first wall surface and having a sound emitting direction to the acoustic blocker. The directional speaker includes a speaker unit, an enclosure of the speaker unit, and an aperture configuring a Helmholtz resonator, wherein a resonance frequency Fr of a Helmholtz resonator is set to be equal to or higher than a reproducible lower limit frequency F min of the speaker unit.
