Electronic device having antenna on grounded speaker box
First Claim
1. An electronic device, comprising:
- a conductive housing structure;
a speaker box having a wall that includes at least one metal structure;
grounding path structures that ground the metal structure to the conductive housing structure; and
an antenna supported by the speaker box, wherein the grounding path structures have an opening, are shorted to the metal structure, and comprise a metal fastener that passes through the opening.

Abstract
An electronic device may be provided with a housing in which electrical components are mounted. The housing may include a metal portion that serves as ground. An antenna for the electronic device may be formed from metal traces on an antenna support such as a flexible printed circuit. The flexible printed circuit may be mounted to a speaker box. The speaker box may have one or more walls formed from metal plates. A metal plate in a speaker box may be coupled to a metal clip. The metal clip may be shorted to a metal stiffener that overlaps a tail portion of the flexible printed circuit. The metal stiffener may have an opening that is aligned with an opening in the metal clip. A metal fastener such as a screw may pass through the openings to short the metal clip, stiffener, and metal plate to ground.
