The invention relates to the field of acoustics, in particular to an acoustic device and an audio system, and the acoustic device comprises a loudspeaker driver and a waveguide structure. A waveguide structure is disposed around the speaker driver, the waveguide structure having a first frequency response corresponding to sound emitted from the speaker driver traveling directly to the listening position such that a head-related transfer function is added to the sound emitted from the speaker driver traveling directly to the listening position, the head-related transfer function provides a height cue for sound traveling directly from the speaker driver position to the listening position, thereby simulating sound from above the listening environment; and a second frequency response corresponding to sound emitted from the speaker driver that needs to travel through reflection to the listening position, the ratio of the first frequency response and the second frequency response being equal to a head-related trans
