Olfactory display

摘要

[Structure] An olfactory display 10 includes a housing 12 having an emitting port 22, and presents a fragrance within a range bounded in terms of time and space. Within the housing 12, a fragrance chamber 14 having an air inlet 26 and a fragrance outlet 24 which is communicated with the emitting port 22 is formed, and in the fragrance chamber 14, a solid-like fragrance source 20 is accommodated. Furthermore, in the fragrance chamber 14, there is provided with a airflow source 16 comprising a diaphragm 34 having a piezoelectric device 32. In presenting a fragrance, an air is sent into the fragrance chamber 14 from the air inlet 26 by the airflow source 16, and accordingly, the air within the fragrance chamber 14, which including a gas-like fragrance component volatilized from the fragrance source 20 is emitted from the emitting port 22 passing through the fragrance outlet 24.
