HOUSING AND ELECTRONIC DEVICE USING THE SAME

Abstract

A housing for an electronic device includes a ceramic patterned light transmitting portion and a ceramic light resistant portion surrounding the light transmitting portion. A thickness of the light transmitting portion is in a range from 0.2 mm to 1 mm. A thickness of the light resistant portion is at least 0.3 mm thicker than that of the light transmitting portion.

Description

BACKGROUND

1. Technical Field

The present disclosure relates generally to device housings, and especially to a housing for an electronic device.

2. Description of Related Art

Commonly used housings for an electronic device often includes manufacturer and identifying graphics on an outer surface thereon. However, the normally printed graphics are easily peeled off or abraded away.

Therefore, there is room for improvement within the art.

BRIEF DESCRIPTION OF THE DRAWINGS

The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the views.

FIG. 1 is a cross section of an embodiment of an electronic device, in which the electronic device includes a housing.

FIG. 2 is an isometric view of the housing shown in FIG. 1.

FIG. 3 is a cross section of the housing shown in FIG. 2, taken along the line III-III.

DETAILED DESCRIPTION

Referring to FIG. 1, an embodiment of an electronic device 100 includes a main body 11, a housing 13 covering on the main body 11 and a light source 15 positioned in the main body 11. The housing 13 is ceramic material. The housing 13 includes a ceramic light transmitting portion 131 and a ceramic light resistant portion 133 surrounding the light transmitting portion 131. The light source 15 faces the light transmitting portion 131, and supplies light for the light transmitting portion 131. In the illustrated embodiment, the electronic device 100 is a cell phone, and the light source 15 is a light emitting diode, although the electronic device 100 may alternatively be a music player or a personal digital assistant.

Also referring to FIGS. 2 and 3, the housing 13 is rectangular in shape. The light transmitting portion 131 is formed in an inner surface of the housing 13. The light transmitting portion 131 is patterned in the illustrated embodiment, and forming a decorative pattern. Alternatively, the light transmitting portion 131 may form a specific graphic design pattern. A thickness of the light transmitting portion 131 is in a range from 0.2 mm to 1 mm, such that light can easily transmit therethrough, and the light transmitting portion 131 would not be easily broken. The light resistant portion 133 is at least 0.3 mm thicker than the light transmitting portion 131, thus most of the light can be blocked. The thickness of the light transmitting portion 131 is preferably from 0.3 mm to 0.6 mm. The thickness of the light resistant portion 133 is larger than 1.4 mm, to enhance the physical strength of the housing 13. In the illustrated embodiment, the thickness of the light transmitting portion 131 is 0.5 mm, and the thickness of the light resistant portion 133 is 1.5 mm.

A light transmission ratio of the light transmitting portion 131 is greater than that of the light resistant portion 133 due to the difference in thickness, such that the pattern can be seen more clearly. Since the light transmitting portion 131 is formed in the inner surface of the housing 13, dust or other contaminants outside is prevented from adhering on the light transmitting portion 131. Alternatively, the light transmitting portion 131 can be formed in an outer surface of the housing 13. The pattern can be clearly seen, even after long usage.

It should be noted that the light transmitting portion 131 and the light resistant portion 133 may be made of other ceramic material having different light transmission ratio, for example, the light transmitting portion 131 can be alumina with higher light transmission ratio, and the light resistant portion 133 can be zirconia with lower light transmission ratio than alumina, to as to ensure that the pattern is highly visible.

It should be noted that the light resistant portion 133 may be patterned, and be surrounded by the light transmitting portion 131. When the light source 15 is turned on, the pattern of the light resistant portion 133 is darker than that of the light transmitting portion 131 surrounding the light resistant portion 133, but nevertheless, is still visible.

It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages.
