Abstract

An electronic device may have a housing with metal sidewalls. One of the metal sidewalls may have an opening. The electronic device may have a speaker module that has a speaker housing member. Conductive structures on the speaker housing member may have an opening that forms a slot element. The opening of the metal sidewall may be aligned with slot element. The slot element and an interior cavity of the speaker housing member may form a cavity-backed slot antenna. An antenna feed structure may be disposed at the opening of the speaker housing member. An antenna feed may be directly coupled to the antenna feed structure. The antenna feed structure may indirectly feed the slot antenna resonating element by capacitive coupling. A sealing member may be disposed at the opening of the metal sidewall.

Dependent claims

An electronic device, comprising:

a speaker box having an interior surface that defines a cavity and having conductive structures formed on an exterior surface of the speaker box, the conductive structures having an opening that serves as an open end for the cavity;
and
an antenna that comprises:
a slot antenna radiating element formed from the opening, the opening being partially defined by first and second opposing edges of the conductive structures;
and
an antenna feed structure that is configured to indirectly feed the slot antenna radiating element and that has third and fourth opposing edges, the third edge being capacitively coupled to the first edge and the fourth edge being capacitively coupled to the second edge.
