A lens unit includes a plurality of lenses arranged in an optical axis direction, a lens barrel, and a retainer. The lens barrel has an opening larger than outer diameters of the plurality of lenses and contains the plurality of lenses. The retainer holds the plurality of lenses by contacting, from a side adjacent to the opening in the lens barrel, one of the plurality of lenses that is closest to the opening. Each of the plurality of lenses has an object-side surface and an image-side surface which each include a flat portion that extends radially inward from an outer edge of the lens and that is perpendicular to the optical axis direction of the lens. Each of the plurality of lenses is held in planar contact with a holder at the flat portion. The retainer holds the plurality of lenses by biasing the plurality of lenses in the optical axis direction.

Lens unit, imaging device, and mobile object

An electronic device in which a vibration generator is attached to a panel allows further improvement in sound pressure characteristics. An electronic device () includes a housing (), a panel () held by the housing (), a vibration generator () attached to the panel (), and a sheet member () between the housing () and the panel (). The panel () deforms due to deformation of the vibration generator () to transmit human body vibration sound to an object that contacts the panel (). A first portion of the sheet member () is joined to the panel (), and a second portion of the sheet member () differing from the first portion is joined to the housing (). Between the first portion and the second portion, the sheet member () includes an area to which neither the panel () nor the housing () is attached.

Electronic device

According to one of aspects, provided is an electronic device including a panel, a piezoelectric elementattached to the panel, and a substrateattached to a main surface of the piezoelectric element. The panelis configured to be deformed due to deformation of the piezoelectric element, and sound is transmitted to an object that is in contact with the deformed panel. The substrateincludes a basemade of resin, and signal linesandlaminated with the baseand connected to the main surface of the piezoelectric element. The substantially the entire main surface of the piezoelectric elementis covered by the base

Unit, electronic device, and method of manufacturing electronic device

Excessive deformation of a piezoelectric element is reduced. An electronic apparatusaccording to the present invention includes a panel, a piezoelectric element, a housingfor mounting the panel, and an intermediate memberattached to the piezoelectric element, wherein the intermediate memberand the paneldeform due to deformation of the piezoelectric element, thereby delivering an air conduction sound and a human body vibration sound to an object in contact with the panelthat is deforming.

Electronic apparatus, panel unit, and unit for electronic apparatus

According to an aspect, a device includes: a display unit for displaying a screen; a sensor for detecting an inclination of the display unit; an operating unit for detecting an operation; and a controller. The controller changes an orientation of the screen depending upon the inclination detected through the sensor and the operation detected through the operation unit.

Device, method and storage medium storing program for controlling screen orientation

An electronic device is provided with a housing, a piezoelectric element, and a panel, which is attached to the housing and has a contact area contacting a part of human body, configured to vibrate by the piezoelectric element to generate a vibration sound to be transmitted by vibrating the part of human body, such that pressure from inside of the housing at the contact area of the panel is smaller than pressure from inside of the housing at different area from the contact area. Thereby the sound pressure property is improved, and thus the electronic device preferably transmits air conduction sound and vibration sound.

An impact resistant mobile electronic device is disclosed. A case comprises a first circuit board and a second circuit board, and is elongated in a first direction. The second circuit board is smaller than the first circuit board and is elongated in a second direction substantially perpendicular to the first direction. The second circuit board comprises one or more electrical components elongated in a fourth direction. The first circuit board may be elongated in a third direction substantially perpendicular to the second direction.

Mobile electronic device providing impact resistance to electronic component

An electronic device able to stably disperse heat generated by an electronic component is provided. By providing a heat dissipating metal plate having a high heat conductivity between a TV tuner and a battery, heat generated by the TV tuner is dispersed to the battery having a large heat capacity and further dissipated to the outside of a case through a battery lid.
