Abstract: A smell producing and outputting device capable of providing a certain smell correspondingly to a certain image or a certain sound is disclosed. The disclosed smell producing and outputting device comprises: an audio processing unit for detecting an image signal or a sound signal; and a smell producing and outputting unit including a smell storing reservoir, a compression part, a driving part, and an outside shell, wherein the smell storing reservoir, the compression part, the driving part are received by the outside shell, and the driving part is electrically connected with the audio processing unit. When a certain image signal or a certain sound signal is received by the audio processing unit, the audio processing unit outputs a driving signal to the driving part, for changing the position of the compression part. Thus, a smell is driven out from the smell producing and outputting unit and distributed in the atmosphere.
