Abstract: A loudspeaker includes a frame, a magnetic circuit provided with a magnetic gap, a cone-shaped diaphragm, a voice coil, and an LED. The magnetic circuit is connected to a lower part of the frame. The diaphragm is connected to an outer periphery of the frame. A first end of the voice coil is connected to the diaphragm, and a second end thereof is inserted into the magnetic gap. The LED is provide on an upper part of the frame, and outputs light toward the center of the diaphragm. The LED is disposed such that the diaphragm reflects the light.

Abstract: A loudspeaker diaphragm includes a cone having a curved surface from the outer to the inner periphery, and an annular edge of which inner peripheral part is bonded to the front side of the outer peripheral part of the cone. When seen from the front, the outer periphery of the cone is defined by smooth connection of three larger-diameter parts tangent to a first circle with a larger diameter, and three smaller-diameter parts each located between adjacent two of the three larger-diameter parts and tangent to a second circle with a smaller diameter. In the cone, a shape defined by connecting together points at the same position on the central axis is more circular as the points approach the inner periphery from the outer periphery. The inner periphery of the edge has a smaller radius than the second circle.

Abstract: A loudspeaker to be attached to an attachment member, the loudspeaker including: a temporary joint pin which is inserted into a temporary joint hole and temporarily holds the loudspeaker in a suspended state. The temporary joint pin includes a rod-like portion backwardly projects from a rear end surface of a frame; a tilted surface portion which is part of an inner circumferential surface of a circumferential surface of the rod-like portion to be brought into contact with the temporary joint hole, and is tilted to become closer to the central axis of the rod-like portion from a base end toward a distal end of the rod-like portion in a direction of projection; and a flanged portion which is adjacent to the tilted surface portion at the distal end of the rod-like portion, protrudes in a direction crossing the direction of projection, and catches onto the attachment member.

IPC: H04R1/02
Abstract: A loudspeaker device includes a loudspeaker unit and an enclosure. The loudspeaker unit outputs sounds mainly in a first direction, upon receiving an electric signal. The enclosure is configured with at least a part of an interior member of a movable-body device, and secures and accommodates the loudspeaker unit in the inside of the enclosure. The interior member includes a body part, and an accommodation part that accommodates the loudspeaker unit therein and is formed integrally with the body part. The accommodation part is larger in dimension along the first direction than the body part.

Abstract: A failure detection device according to the present disclosure is a failure detection device that detects a failure of an input interface device detecting a position on a screen, the position being selected by an input operation. The failure detection device includes a memory, and a controller connectable to the input interface device. The controller acquires position information of a predetermined selected region on a screen, calculates a counted number of determinations that the predetermined selected region is not present on a selected position on the screen, and determines that an input interface device is in an abnormal state in a case where the counted number satisfies a predetermined condition.
