Abstract

An electronic apparatus is disclosed. In one embodiment, an electronic apparatus comprises a display, a cover member, a piezoelectric vibrating element, a controller, a housing, a bonding material, and an intervening member. The bonding material between the housing and a peripheral end of an inner surface of the cover member is configured to bond the housing and the cover member. The inner surface of the cover member includes a partial region in which the bonding material is absent. The partial region includes a region in which the piezoelectric vibrating element is located and extends to one part of a periphery of the inner surface. The intervening member is located between the housing and a region of the partial region close to the one part of the periphery relative to the piezoelectric vibrating element and is less likely to interfere with a vibration of the cover member than the bonding material.

Claims6

Dependent claims

An electronic apparatus comprising:

a display;
a cover member that is located on a surface of the electronic apparatus and is configured to cover a display surface of the display;
a housing, wherein the housing comprises a protrusion from an inner surface of the housing that is opposite the cover member, wherein the protrusion is bonded by a bonding material to an inner surface of the cover member at a position between the display and an edge of the cover member in a plan view, and wherein the inner surface of the cover member includes a partial region, between the bonded protrusion of the housing and the edge of the cover member, in which the bonding material is absent;
a piezoelectric vibrating element that is located in the partial region of the inner surface of the cover member between the bonded protrusion of the housing and the edge of the cover member in the plan view;
a controller configured to cause the piezoelectric vibrating element to vibrate based on a sound signal;
and
an intervening member that is located in the partial region of the inner surface of the cover member on an opposite side of the piezoelectric vibrating element than the bonded protrusion of the housing in the plan view, wherein the intervening member is less likely to interfere with a vibration of the cover member than the bonding material.
