An electronic device of the present disclosure includes a casing, a translucent panel including a curved portion the curved portion being bent toward the casing, and a touch panel located on a rear surface of the translucent panel, the touch panel covering the curved portion, the touch panel including a transparent electrode or a wire electrically connected to the transparent electrode. The touch panel includes a curved region facing the curved portion. The transparent electrode and/or the wire include/includes an inclined wiring portion located in the curved region.

Electronic device

An electronic device includes a substrate body serving as a base including a first surface and a second surface facing opposite sides to each other, a dome switch located on the first surface, a waterproof sheet located to include a portion configured to cover the dome switch, and an adhesive layer located on at least part of the waterproof sheet. The waterproof sheet is affixed to the base or another component with the adhesive layer so as to leave a watertight space including the dome switch.

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.

A mobile terminal according to the present disclosure includes a housing member with a first sound hole, a film speaker and a speaker holder with a second sound hole. The film speaker includes a piezoelectric element and a resin film configured to vibrate with the piezoelectric element. The film speaker is located in the speaker holder. The second sound hole corresponds to the first sound hole and is located between the first sound hole and the film speaker. An inner edge which defines the second sound hole extends above the film speaker. A surface of the inner edge facing the film speaker is inclined such that at least a part of the inner edge decreases in thickness toward a leading end of the inner edge.

Mobile terminal

An electronic device according to the present disclosure includes a translucent panel including a front surface and a back surface, the translucent panel including a curved portion at an end portion, the curved portion being curved toward the back surface with respect to a central portion of the translucent panel. The electronic device also includes a touch panel located on the back surface of the translucent panel and configured to be covered with the central portion and the curved portion. The distance between the curved portion and the touch panel is shorter than the distance between the central portion of the translucent panel and the touch panel.

An electronic device according to an embodiment of the present disclosure includes a translucent panel and a casing to which the translucent panel is attached. The translucent panel includes a curved portion curved toward the casing. The casing includes an attaching surface facing an end surface of the translucent panel, the end surface facing the casing. A distance between an end of the end surface of the translucent panel and a portion of the attaching surface of the casing facing the end of the end surface is longer than a distance between a middle portion of the end surface of the translucent panel and a portion of the attaching surface of the casing facing the middle portion.

An electronic device includes a case, a panel which includes a first surface including a contour line and is held by the case such that the first surface faces outward, the contour line being provided with a first recess, a first component located in the case, and a cover which is provided with a through hole or a cut for communication between the first component and the outside and is located to hide the first recess when the first surface is two-dimensionally viewed.

An electronic device according to an embodiment includes a casing and a translucent panel attached to the casing. The translucent panel has a curved portion curved toward the casing. The casing includes an attaching surface and a sidewall. The attaching surface faces an end surface of the translucent panel. The sidewall is located to be raised from the attaching surface toward a back surface of the curved portion, and is inclined from a direction perpendicular to the attaching surface toward a central portion of the translucent panel.

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

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.
