CO-MOLD FEATURES ON A CHASSIS SHELL OF A MOBILE DEVICE

摘要

A mobile device can include a unibody component (e.g. chassis shell) with at least a co-mold feature that isolates a contiguous portion of the unibody component from an outer portion of the unibody component. For example, the outer portion and the contiguous portion can be made of an electrically conductive material. The co-mold feature can be made of non-conductive material that electrically isolates the contiguous portion from the outer portion. The co-mold feature can be made by co-molding a resin material in a channel cut into a piece of metal and later exposing the cured resin material on two sides.

1. A mobile phone, comprising:
a circuit board having a processor thereon; and a chassis shell having an integral unibody including a co-mold loop feature surrounding a button profile feature, wherein the co-mold loop feature is integrally bonded to both the button profile feature and a passive part of the chassis shell surrounding the co-mold loop feature, wherein the button profile feature is composed of a first material different from a second material composing the co-mold loop feature; and a sensor system coupled to the circuit board and the button profile feature from an interior side of the chassis shell, wherein the sensor system is configured to detect a user interaction event based on sensor readings from the sensor system and to register the user interaction event with the processor.
