<p> This 3D audio effect device uses a right speaker (R1) and a left speaker (L1) to exclusively provide 3D audio effects to a person seated in a seat (100). The right speaker (R1) is the ultrasonic wave generating means of a right ear parametric speaker (2) that transmits ultrasonic waves towards the position of the right ear of a person (200) seated in the seat (100) and generates playback sound in the right ear. The left speaker (L1) is the ultrasonic wave generating means of a left ear parametric speaker (3) that transmits ultrasonic waves towards the position of the left ear of the person (200) seated in the seat (100) and generates playback sounds in the left ear. The right speaker (R1) and the left speaker (L1) are arranged above the position of the head of the person (200) seated in the seat (100).</p> |
