Abstract
Systems, methods, and computer-readable media are disclosed for ring-shaped devices with combined Bluetooth and NFC antenna assemblies. In one embodiment, an example device may include an inner shell, an outer shell coupled to the inner shell, where the outer shell and inner shell together form a first side portion, a second side portion, and a lower portion of the ring-shaped device, a battery, and an antenna assembly that forms an upper portion of the ring-shaped device. The antenna assembly may include a metal substrate, a ferrite layer disposed on the metal substrate, and a metallic loop structure disposed on the ferrite layer.
Claims20
A ring-shaped device comprising:
- a housing comprising a curved upper portion, a curved lower portion, a first curved side portion, and a second curved side portion;
- a curved antenna assembly that forms the curved upper portion of the housing, the curved antenna assembly comprising:
- a metal substrate configured for wireless communication over a Bluetooth protocol;
- a ferrite layer disposed on the metal substrate;
- and
- a metallic loop antenna disposed on the ferrite layer, the metallic loop antenna configured for wireless communication over a Near-Field Communication (NFC) protocol;
- a battery;
- a wireless charging coil coupled to the battery;
- a flexible printed circuit assembly coupled to the curved antenna assembly and the battery, the flexible printed circuit assembly disposed within the first curved side portion of the housing, the flexible printed circuit assembly comprising a microphone configured to receive speech input, and a speaker assembly, wherein the microphone and the speaker assembly are disposed within the curved lower portion of the housing;
- and
- a button assembly disposed along the curved lower portion of the housing.
A ring-shaped device comprising:
- an inner shell;
- an outer shell coupled to the inner shell, wherein the outer shell and inner shell together form a first side portion, a second side portion, and a lower portion of the ring-shaped device;
- a battery;
- an antenna assembly that forms an upper portion of the ring-shaped device, the antenna assembly comprising:
- a metal substrate;
- a ferrite layer disposed on the metal substrate;
- and
- a metallic loop structure disposed on the ferrite layer;
- a first side portion having a first thickness;
- and
- a second side portion having the first thickness, wherein the first thickness is equal to or less than a second thickness of the lower portion and a third thickness of the upper portion.
A ring-shaped device comprising:
- a ring-shaped housing comprising an outer shell, an inner shell, and an antenna assembly that forms a top portion of the ring-shaped device, wherein the antenna assembly comprises:
- a metal substrate;
- a ferrite material disposed on the metal substrate;
- and
- a loop antenna disposed on the ferrite layer;
- a battery;
- a flexible printed circuit assembly;
- and
- a first microphone disposed along a lower portion of the ring-shaped housing.
