Abstract

[Object] To suppress cracking and breakage of a light-transmissive cover plate when an electronic apparatus receives an impact.
[Solution] An electronic apparatus is provided. The electronic apparatus includes a case body including a single crystal body in at least a portion thereof, the single crystal body containing alumina (Al 2 O 3 ) as a main component; a plurality of information processing devices in the case body; and a thermally conductive portion that thermally connects at least one of the information processing devices to the single crystal body.

First claim

1 . An electronic apparatus comprising:
a case body including a single crystal body in at least a portion thereof, the single crystal body containing alumina (Al 2 O 3 ) as a main component; a plurality of information processing devices in the case body; and a thermally conductive portion that thermally connects at least one of the information processing devices to the single crystal body.

2 . The electronic apparatus according to claim 1 , further comprising:
an image display device in the case body, the image display device including an image display surface, wherein the case body includes a light-transmissive cover plate including a first principal surface that faces the image display surface and a second principal surface opposite to the first principal surface, and wherein the light-transmissive cover plate includes the single crystal body, and the at least one of the information processing devices is thermally connected to the single crystal body through the thermally conductive portion.

3 . The electronic apparatus according to claim 2 , wherein the light-transmissive cover plate includes a display portion on which an image of the image display surface is displayed and a peripheral edge portion that surrounds the display portion, and the thermally conductive portion is in contact with the peripheral edge portion.

4 . The electronic apparatus according to claim 3 , further comprising a light shielding layer provided on the single crystal body in the peripheral edge, wherein the light shielding layer blocks the image of the image display surface, and the thermally conductive portion is connected to the light shielding layer.

5 . The electronic apparatus according to claim 1 , wherein the thermally conductive portion includes a high-thermal-conductivity body containing a single crystal of alumina (Al 2 O 3 ) or a metal as the main component.

6 . The electronic apparatus according to claim 1 , wherein the thermally conductive portion includes a circuit board on which the information processing devices are disposed.

7 . The electronic apparatus according to claim 1 , wherein the information processing devices include a central processing unit (CPU), and the CPU is thermally connected to the single crystal body.

8 . The electronic apparatus according to claim 1 , further comprising a piezoelectric vibrating element disposed on the light-transmissive cover plate.

9 . The electronic apparatus according to claim 8 , wherein the piezoelectric vibrating element vibrates when a driving voltage based on a sound signal is applied thereto.

10 . The electronic apparatus according to claim 8 , wherein the piezoelectric vibrating element has a long and narrow rectangular plate shape in a plan view.

11 . The electronic apparatus according to claim 8 , wherein the piezoelectric vibrating element is disposed so as not to overlap the image display device.
