Embodiment Construction

[0016] figure 1 Denotes a mobile telephone MT which has a processor PE (eg a microcontroller) to control the main functions. The housing G of the mobile phone is double-walled at least on its lower front side, which leaves corresponding recesses AUS for the display D, the keyboard TAS, the interfaces, etc. The inner wall IG (housing) of the enclosure matches the shape of the processor PE. In order to achieve the desired appearance, the outer side of the inner wall is white. Here, the outer wall AG of the casing is transparent to visible light. The cavity HR formed by the double-walled housing is liquid-tight and has at least one orifice O (closable to liquid-tight by threads or screws) for the injection of liquid into the cavity. Within the scope of the invention, it is also possible to inject different liquids into several lumens.

[0017] Into this lumen HR is injected a liquid F which contains at least two different color components which are not mixed uniformly and hav...

Abstract

The invention relates to an electronic device comprising an inner housing shell, which at least partially encompasses the electronic elements and an outer housing shell, which at least partially surrounds the inner housing shell. The material that constitutes the inner housing shell and the outer housing shell is impermeable to liquid. The inner and outer housing shells are arranged and configured to form a hollow chamber, impermeable to liquid, which is at least partially filled with a liquid.

Description

technical field [0001] The invention relates to an electronic device, in particular a mobile phone with a processor and a housing. Background technique [0002] The rapid development in the field of daily electronics technology has led to the development of various electronic devices in recent years, and their control is realized by controllers. [0003] As is well known, processor cooling is achieved by heat sinks having increased surface area attached to the processor or by suitable ventilation. Such solutions have the disadvantage of increased bulk, especially for portable devices. [0004] In addition, in order to satisfy consumers' individualized requirements for such electronic devices, replaceable casings are provided to fulfill consumers' individualized requirements for such devices in terms of color or style. However, it has the disadvantage of increasing the cost of the mechanical parts and resulting in a heavier and more expensive device. Contents of the inven...
