It is an object to provide a speaker including a strong magnetic circuit and a method of manufacturing a speaker. To achieve the object, a speaker according to the present technology includes an outer magnet and an inner magnet. The outer magnet has a ring shape and is magnetized along an axial direction of the ring shape. The inner magnet has a circular outer shape when viewed from the axial direction of the outer magnet, is magnetized in a direction opposite to a direction of the outer magnet along the axial direction, and is disposed inside the outer magnet through a gap.

Speaker and method of manufacturing a speaker

[Object] To propose a novel and improved fragrance material holding member and fragrance providing device that can improve persistence of a fragrance material while avoiding an increase in the size of the device. [Solution] Provided is a fragrance material holding member including: an airflow passage through which air supplied from an airflow source passes, the airflow passage being provided to penetrate the fragrance material holding member; and a holding space that branches from the airflow passage and holds a fragrance material.

Fragrance material holding member and fragrance providing device

[Object] To propose a novel and improved fragrance providing device that can be reduced in size. [Solution] Provided is a fragrance providing device including: a fragrance material holding member in which a plurality of holding passages each holding a fragrance material are provided to penetrate the fragrance material holding member; and a rotation mechanism capable of relatively rotating the fragrance material holding member and a member provided with an introduction port that communicates with part of the plurality of holding passages and introduces air supplied from an airflow source to the part of the holding passages, in a manner that the part of the holding passages that communicates with the introduction port is switched.

Fragrance providing device

A perfume retainer includes a main body and an air flow channel located in the main body. The air flow channel includes: a retainer space configured to retain a perfume, a first opening located connecting a first end of the retainer space to a space outside of a first end of the air flow channel, and a second opening connecting a second end of the retainer space to a space outside of a second end of the air flow channel. The retainer space includes a plurality of segment regions arranged adjacent each other such that an external wall of one of the plurality of segment regions is in contact with an external wall of another of the plurality of segment regions. The plurality of segment regions increase a surface area of the air flow channel without increasing a volume of space of the air flow channel.

Perfume retainer member and aroma provision device

[Object] To enable to visually recognizing information displayed on an outer circumferential surface of a member from an axial direction of the member and capable of switching selection elements while viewing the device from the axial direction. [Solution] A rotary switching device includes: a cylindrical first member that includes an outer circumferential surface on which predetermined information is displayed; a second member that is rotatable relative to the first member; a plurality of selection elements among which a selection target is switched in accordance with relative positions of the first member and the second member; a mirror surface part that is formed by a surface disposed around the outer circumferential surface of the first member and intersecting an axial direction of the first member, and that is configured to specularly reflect the information displayed on the outer circumferential surface of the first member to enable the information to be visually recognized from the axial direction of the first member; and an indicating part configured to indicate the selection element that is selected.

Rotary switching device selection element information display

A light guide includes an incident surface, an emitting surface, a reflecting surface, and a light guide section. The incident surface receives light from a plurality of light-emitting elements arranged at least in a first direction. The emitting surface outputs incident light from the incident surface. The reflecting surface includes a plurality of lenses having optical power in the first direction and a second direction different from the first direction and is provided to be opposed to the incident surface. The light guide section includes a surface including the incident surface, the emitting surface, and the reflecting surface, and causes the light that has entered from the incident surface to be reflected by the plurality of lenses of the reflecting surface to guide the light to the emitting surface.

Light guide, light source apparatus, and reading apparatus

A light irradiation apparatus capable of irradiating, while a component having a first side is held on the first side by a holding body of a component mounting apparatus, light onto a reflective plate to irradiate reflected light from the reflective plate from the first side of the component, the light irradiation apparatus including: a plurality of first light-emitting devices; a supporting body configured to support the plurality of first light-emitting devices such that optical-axis directions of the plurality of first light-emitting devices match; and a light guide body configured to guide light emitted from the plurality of first light-emitting devices to the reflective plate so that the reflected light is detected by a detector from a second side of the component on the other side of the first side.
