<p>PROBLEM TO BE SOLVED: To maintain fragrance emission performance even when the number of installation of fragrance chambers is increased, and to present more kinds of fragrances within a range bounded in terms of time and space.SOLUTION: An olfactory display 10 includes a housing 12 and presents a fragrance within a range bounded in terms of time and space. In the housing 12, a plurality of fragrance chambers 28 partitioned with a diaphragm 26 are formed, and an air inlet 62 and a fragrance outlet 64 are formed in each fragrance chamber 28. Each fragrance outlet 64 is communicated with an emitting port 68 via a fragrance channel 70. Additionally, in each fragrance chamber 28, a solid-like fragrance source 30 is accommodated and an airflow source 32 to send air into the fragrance chamber 28 from an air inlet 32 is installed. Furthermore, in the housing 12, an auxiliary airflow source 74 to accelerate a fragrance sent from the fragrance chamber 28 by the airflow source 32 in a fragrance emission direction is installed apart from the airflow source 32.</p> |
