Abstract: An electronic device 10 comprises: first and second antennas 40A, 40B and a speaker 76 within a housing 12, where there is an antenna isolation element located on a moving member 74 of the speaker. The antenna isolation element may be a parasitic resonating slot element formed in a metal foil layer laminated to the moving diaphragm member 74. The antennas may operate as dual-band wireless local area network antennas at 2.4 GHz and 5 GHz. The antennas may be formed by metal traces 72 printed on a circuit board which is separated from the moving member 74 of the speaker by an air gap. Each antenna may have a respective printed circuit shielding cavity 66 with conductive gaskets 62. The electronic device may include a touch sensor and transceiver and control circuitry to drive the speaker 76 to play some desired media content. Also disclosed is an electronic device comprising: a cylindrical housing; a printed circuit, on which there are first and second antennas; and a metal layer having a slot opening which forms an antenna isolation element providing radio frequency isolation between the first and second antennas. An electronic device comprising: a speaker with a movable structure, where a metal layer is on the movable structure and an antenna structure is formed from the metal layer, is further disclosed.

Abstract: An electronic device may have a speaker mounted in a housing. The housing may have a top face and a longitudinal axis that passes through the top face. A printed circuit may lie parallel to the top face. Input-output circuitry such as a touch sensor and other components may be mounted on the top face overlapping the printed circuit. First and second antennas may be formed on the printed circuit. A speaker may be mounted in the housing facing along the longitudinal axis. A metal layer on a movable portion of the speaker may be patterned to form a slot antenna isolation element or other antenna isolation element. The antenna isolation element may be configured to exhibit a resonance at a frequency of operation of the first and second antennas and may therefore enhance isolation between the first and second antennas.
