Abstract: An integrated device package includes a die and a package substrate. The package substrate includes at least one dielectric layer (e.g., core layer, prepeg layer), a magnetic core in the dielectric layer, a first plurality of interconnects configured to operate as a first protective ring, and a second plurality of interconnects configured to operate as a first inductor. The second plurality of interconnects is positioned in the package substrate to at least partially surround the magnetic core. At least one interconnect from the second plurality of interconnects is also part of the first plurality of interconnects. In some implementations, the first protective ring is a non-contiguous protective ring. In some implementations, the first inductor is a solenoid inductor. In some implementations, the magnetic core includes a carrier, a first magnetic layer, and a second magnetic layer.

Abstract: A device comprising a first printed circuit board (PCB); a second printed circuit board (PCB); a first flex board coupled to the first PCB and the second PCB; a first integrated device coupled to the first PCB; a speaker configured to be coupled to the first integrated device; a microphone configured to be coupled to the first integrated device; a second integrated device coupled to the second PCB, wherein the second integrated device is configured to be coupled to the first integrated device through the second PCB, the first flex board and the first PCB; and a power source configured to provide power to the first integrated device and the second integrated device. The first PCB is located between the power source and the first integrated device. The second PCB is located between the power source and the second integrated device.
