Problems solved by technology

That is, there is no realization of cueing odors to a spatially defined range
In addition, the structure is relatively complicated, so there is a certain limit for miniaturization
[0008] In addition, in the technique of Patent Document 2, the fragrance is released to the outside by using two mechanisms of the fragrance releaser and the blower fan, which leads to an increase in the size of the device.
In addition, the air supply (air pressure generation) of the air supply fan depends on the r...

Embodiment Construction

[0071] refer to figure 1 , as an embodiment of the present invention, the olfactory display 10 is used to add smell (olfactory information) to content including video and sound and present it to the user, thereby improving the sense of reality and presence of the content. For example, the olfactory display 10 can be controlled in time and space, that is, within the limited range of time and space, in a manner linked to various audio-visual displays such as personal computers, televisions, radios, game machines, DVD players, video recorders, and mobile phones. Cue the smell.

[0072] figure 1As an example, a situation in which the olfactory display 10 is used in conjunction with a personal computer is shown. figure 2 ) is mounted on the LCD display 100, the keyboard, etc. in such a way that it faces the direction of the user's face.

[0073] Such as figure 2 as well as image 3 As shown, the olfactory display 10 is an ultra-miniature olfactory display formed in a cube sh...

Abstract

The present invention provides an olfactory display (10) which includes a housing (12) that has a spray opening (22) and presents aromas in a temporally and spatially limited range. An aroma chamber (14) that has an in-draft opening (26) and an aroma outlet (24) linked to the spray opening (22) is formed in the housing (12), and an aroma source (20) in a solid form is accommodated in this aroma chamber (14). In addition, a blowing force source (16) provided with a diaphragm (34) to which a piezoelectric element (32) is attached is provided in the aroma chamber (14). When an aroma is presented, air inside the aroma chamber (14), which includes an aroma component in a gaseous form volatized from the aroma source (20) by the blowing force source (16) blowing air into the aroma chamber (14) from the in-draft opening (26), passes through the aroma outlet (24) and is sprayed from the spray opening (22).

Description

technical field [0001] The present invention relates to an olfactory display, in particular to an olfactory display that prompts odors within a limited range of time and space. Background technique [0002] In recent years, various olfactory displays have been proposed that present smells (olfactory information) in conjunction with audio-visual displays such as TVs and personal computers for the purpose of presenting information with a high sense of presence and immersion to the user. Here, when a certain smell is to be presented over a certain period of time, it is sufficient to simply diffuse the smell into the space. However, temporal control (temporal locality) of scent cues is required in order to present odors in a manner consistent with, for example, switching scenes of content presented by an audiovisual display. In addition, in order to present an odor only to, for example, a target person, it is necessary to spatially control (spatial locality) the odor presentati...
