Abstract

An electronic device includes: a main body; a screen panel disposed on a surface of the main body and configured to display an image; a frame-shaped cover panel disposed on the surface of the main body to cover an outer periphery of the screen panel; a bone conduction vibrator incorporated in the main body and attached to a rear surface of the screen panel, and an adhesive layer fixedly attaching the cover panel at a rear surface thereof to an outer peripheral portion of the surface of the screen panel. The adhesive layer extends along the outer peripheral portion of the surface of the screen panel and has a missing portion in which an area to be located in the vicinity of the bone conduction vibrator is missing. The missing portion-provides a gap between the surface of the screen panel and the rear surface of the cover panel.

First claim

The invention claimed is:

1. An electronic device comprising:
a main body;
a screen panel disposed on a surface of the main body and configured to display an image;
a frame-shaped cover panel disposed on the surface of the main body to cover an outer periphery of the screen panel;
a bone conduction vibrator incorporated in the main body and attached to a rear surface of the screen panel, the bone conduction vibrator being configured to transmit audio by bone conduction; and
an adhesive layer fixedly attaching the cover panel at a rear surface thereof to an outer peripheral portion of a surface of the screen panel,
wherein the adhesive layer extends along the outer peripheral portion of the surface of the screen panel and has a missing portion in which an area to be located in the vicinity of the bone conduction vibrator is missing, and the missing portion in the adhesive layer provides a gap between a portion of the outer peripheral portion of the surface of the screen panel and the rear surface of the cover panel.

2. An electronic device comprising:
a main body;
a screen panel disposed on a surface of the main body and configured to display an image;
a frame-shaped cover panel disposed on the surface of the main body to cover an outer periphery of the screen panel;
a bone conduction vibrator incorporated in the main body and attached to a rear surface of the screen panel, the bone conduction vibrator being configured to transmit audio by bone conduction; and
an adhesive layer fixedly attaching the cover panel at a rear surface thereof to an outer peripheral portion of a surface of the screen panel,
wherein the adhesive layer extends along the outer peripheral portion of the surface of the screen panel and has a missing portion in which an area to be located in the vicinity of the bone conduction vibrator is missing, and the missing portion in the adhesive layer provides a gap between the surface of the screen panel and the rear surface of the cover panel, and
wherein the gap has a dimension adapted to prevent the surface of the screen panel, to be vibrated upon driving of the bone conduction vibrator, from contacting a rear surface of an inner peripheral portion of the cover panel.

3. The electronic device according to claim 1 , wherein the bone conduction vibrator is positioned on an outer side of an image display area of the screen panel.

4. An electronic device comprising:
a main body;
a screen panel disposed on a surface of the main body and configured to display an image;
a frame-shaped cover panel disposed on the surface of the main body to cover an outer periphery of the screen panel;
a bone conduction vibrator incorporated in the main body and attached to a rear surface of the screen panel, the bone conduction vibrator being configured to transmit audio by bone conduction; and
an adhesive layer fixedly attaching the cover panel at a rear surface thereof to an outer peripheral portion of a surface of the screen panel,
wherein the adhesive layer extends along the outer peripheral portion of the surface of the screen panel and has a missing portion in which an area to be located in the vicinity of the bone conduction vibrator is missing, and the missing portion in the adhesive layer provides a gap between the surface of the screen panel and the rear surface of the cover panel,
wherein the cover panel includes a frame-shaped first panel member that covers the outer periphery of the screen panel, and a second panel member extending along a rear surface of the first panel member and fixedly attached to a rear surface of an inner peripheral portion of the first panel member by an adhesive, and
wherein the second panel member has an inner peripheral portion extending further from an inner peripheral edge of the first panel member toward a central portion of the screen panel, and an upright wall is provided on a surface of the inner peripheral portion, the upright wall being higher than a surface on which the inner peripheral portion of the first panel member is fixedly bonded.

5. The electronic device according to claim 1 , wherein an anti-soil coating is provided on the surface of the screen panel over a central area excluding an outer peripheral area in which the adhesive layer is present.
