Embodiment Construction

[0027] The present invention relates to antennas for use in wearable devices. Although described herein generally with respect to a near-field magnetic induction (NFMI) antenna for use in an earphone within a set of earphones, it should be understood that the invention is not limited to this particular application and may be used for use in other types of Inductive antennas in devices, including other types of wearable devices.

[0028] figure 1 An example of a system 10 is shown comprising a first wearable device 10A in the form of earphones and a second wearable device 10B also in the form of earphones, each wearable device having an earphone housing 12 with a central portion 13 and upper part 16 and lower part 18. Light guide assembly 20 is shown operatively connected to the housing to provide selective illumination to provide feedback to the user. figure 2 An exploded view of wearable device 10A is provided. Waterproof pad 24 and protective net 26 are shown. Furtherm...

Abstract

A wearable device includes a housing, a first short range transceiver for far field communication disposed within the housing, a second short range transceiver for near field communication disposed within the housing, wherein the second short range transceiver for near field communications comprises a core and a plurality of coil turns wrapped around the core. The wearable device further includesa generally planar printed circuit board disposed within the housing and having a plurality of components mounted thereto. The core is mounted perpendicularly to the plurality of components mounted onthe generally planar printed circuit board to thereby reduce electromagnetic interference. The wearable device may be an earpiece. The core may be mounted at a posterosuperior portion of the wearabledevice.

Description

[0001] priority statement [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 211725, filed August 29, 2015, and U.S. Utility Model Application No. 14 / 941,639, filed November 15, 2015, which are incorporated by reference The whole unites here. technical field [0003] The present invention relates to antennas. More particularly but not exclusively, the invention relates to antennas for use in wearable devices such as earphones. Background technique [0004] Various types of wireless communication links exist. However, a number of problems may exist when used in certain environments and / or applications. For example, in the case of a wearable device where the left earpiece is to communicate with the right earpiece, using a Bluetooth wireless transceiver can be problematic due to a combination of factors involving attenuation, reliability in changing environments, and sensitivity. An alternative is to use near-field magnetic induction (NF...
