An audio system for an elevator includes two or more speaker cabinets arranged inside a suspended ceiling fixed to a ceiling board of a car of the elevator, an input device to which sound content radiated to an inside of the car from each of the two or more speaker cabinets are input, and a sound field control device configured to conduct phase control and reverberation time control for the sound content and thereby cause a sound wave based on the sound content to be radiated from the speaker cabinet to the inside of the car. Each of the speaker cabinets includes a casing arranged inside the suspended ceiling, and a speaker unit arranged inside the casing and having a radiation surface that radiates the sound wave.
