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.

Electronic device with speaker and antenna isolation

An accessory such as a wireless earbud may have an antenna for transmitting and receiving wireless signals. A housing for the earbud may have a main body portion and an extended portion that forms a stalk protruding from the main body portion. The earbud may have a speaker aligned with a speaker port in the main body portion. The antenna may have an elongated shape and may extend along the stalk. The stalk may have a plastic housing wall portion. The antenna may be formed from first and second metal traces on opposing sides of a printed circuit substrate. The first metal trace may form an antenna resonating element arm and may lie between the substrate and the plastic housing wall portion. The second metal trace may be a ground trace. A feed for the antenna may be located at a juncture between the main body portion and the stalk.

Antennas for wireless earbuds

An accessory such as a wireless headset may have an antenna for transmitting and receiving wireless signals. First and second earbuds may be coupled to different ends of a housing for the accessory. A rigid flex printed circuit board in the housing may include a rigid printed circuit portion. The rigid printed circuit portion may include first and second rigid printed circuit layers. A first portion of a flexible printed circuit may be interposed between the first and second rigid layers. A second portion of the flexible printed circuit may extend from an end of the rigid layers and may be wrapped around the first rigid layer. Planar inverted-F antenna resonating element, antenna shorting, and antenna feeding traces may be formed on the second portion of the flexible printed circuit. The efficiency of the antenna may be undisturbed by the presence of a user's body adjacent to the accessory.

Wireless headset antennas

An electronic device may have wireless circuitry with antennas. The electronic device may have a dielectric housing. A printed circuit board with electrical components may be mounted in the dielectric housing. Heat spreader structures may be used to dissipate heat from the electrical components. The heat spreader structures be configured to form antenna cavities. The antennas in the electronic device may be formed from the antenna cavities and may have antenna resonating elements formed on the printed circuit. An electrical component such as a light-emitting diode may be mounted in one of the antenna cavities. Each antenna element may be an inverted-F antenna resonating element with short and long arms. The short arm of each antenna resonating element may be formed from edge plated metal traces on an edge of the printed circuit.
