ESD protection in a very small form factor consumer electronic product
First Claim
1. A media player, comprising:
- a housing having an anodized aluminum surface; and
a button assembly that includes an external feature arranged to receive a user input event, the external feature being connected to an internal switch displaced from the external feature by way of an electrically conductive arm that fits through a slit in a moisture flow inhibiting seal formed of an insulating material, wherein at least a portion of the seal is combined with a conductive dopant such that a conductive path is formed between the electrically conductive arm and a portion of the anodized surface of the housing along which a portion of a surface layer has been removed, the conductive path allowing a quantity of charge deposited at the external feature to flow directly to the portion of the anodized surface of the housing by way of the electrically conductive arm and the conductive portion of the seal, thereby bypassing the internal switch.

Abstract
A very small form factor consumer electronic product includes at least a single piece housing having an integral front and side walls that cooperate to form a cavity in cooperation with a front opening where an edge of the side walls define a rear opening and at least some of the edges have flanges. The consumer electronic product also includes an user input assembly having a size and shape in accordance with the front opening and a clip assembly having a size and shape in accordance with the rear opening and having an external user actionable clip, a plurality of internal hooking features, and a plurality of internal latching features. The clip assembly is secured by engaging at least some of the hooking features and the flanges on the edges of the housing and engaging the latching features and corresponding attachment features on the internal support plate.

4. A media player, comprising:
a housing having an anodized aluminum surface; and
a button assembly comprising;
an external feature arranged to receive a user input event, an electrically conductive arm arranged to connect the external feature to an internal switch, a metal base portion integrally formed with the external feature, the metal base portion connecting the external feature to the electrically conductive arm; and
a metal label conductively mounted to the metal base portion, wherein the metal label is conductively mounted to the metal base portion using a conductive adhesive such that a conductive path is formed between the external feature and a portion of the aluminum surface of the housing along which a surface layer has been substantially removed by way of the metal label and the metal base portion, the conductive path allowing a quantity of charge deposited at the external feature to flow directly to the portion of the anodized surface of the housing and bypass the internal switch.- View Dependent Claims (5, 6)

7. A method comprising:
-
obtaining a housing comprising an anodized aluminum surface, the housing having at least one opening; obtaining a button assembly that includes an external feature arranged to receive a user input event, the external feature being connected to an internal switch displaced from the external feature by way of an electrically conductive arm; obtaining a block formed of an electrically insulating and moisture resistant material having a slot sized to accommodate the electrically conductive arm; introducing a conductive dopant into at least a portion of the block such that the portion of the block is electrically conductive; inserting the external feature into the opening in the housing; and inserting the electrically conductive arm into and through the slot in electrical contact with the conductive portion of the block, wherein a conductive path is formed between the external feature and a portion of the anodized aluminum surface along which a surface layer has been substantially removed by way of the electrically conductive arm and the conductive portion of the block, the conductive path allowing a quantity of charge deposited at the external feature to flow directly to the portion of the anodized aluminum surface of the housing, thereby bypassing the internal switch. - View Dependent Claims (8, 9)
