PROBLEM TO BE SOLVED: To obtain a loudspeaker unit capable of protecting loudspeakers, and to provide an audio output robot device. SOLUTION: A sheet metal 20(21) on which a magnetic force corresponding to leak magnetic flux of a right-side magnet 10B (left-side magnet 11B) of a right loudspeaker 10 (left speaker 11) is exerted, when a right-side opening/closing part 6 (left-side opening/closing part 7) is closed, with respect to a right-side turning part 4 (left-side turning part 5), is provided on the right-side opening/closing part 6 (the left-side opening/closing part 7). Thus, in a state where the right-side opening/closing part 6 (the left-side opening/closing part 7) is closed, with respect to the right-side turning part 4 (the left-side turning part 5), a state where the right-side opening/closing part 6 (the left-side opening/closing part 7) is closed, with respect to the right-side turning part 4 (the left-side turning part 5) can be maintained by energizing in the closing direction, due to the metal sheet 20(21), and thereby, the right loudspeaker 10 (the left speaker 11) is protected.
