First Claim
Patent Images
1. A wireless headphone, comprising:
- a body configured to fit onto a user'"'"'s head, the body defining opposed ends;
a first speaker coupled to the body and juxtaposed with the first end;
a second speaker coupled to the body and juxtaposed with the second end;
at least first and second antennas coupled to the body; and
at least one wireless receiver supported by the body and electrically connected to at least one of the antennas, wherein the first antenna has a first nulling direction and the second antenna has a second nulling direction, the second nulling direction is orthogonal to the first nulling direction.

Abstract
A wireless headphone assembly has left and right speakers attached to ends of a headphone body, and at least two antennas, e.g., one located at each speaker. Since multiple antennas are used, reception can be improved using one of several approaches, e.g., simple selection of the “best” antenna, multiplexing antenna input, using diversity algorithms such as multiple input multiple output (MIMO) algorithms, etc.

9. A wireless headphone, comprising:
-
a body defining opposed ends; a first speaker coupled to the body and juxtaposed with the first end; a second speaker coupled to the body and juxtaposed with the second end; at least first and second antennas coupled to the body; and means for selectively combining signals from the antennas into an audio stream playable by the speakers using a protocol which includes transmitting signals to the speakers that alternate between signals from the first antenna and signals from the second antenna in a succession such that differences between the two signals are substantially imperceptible to a user. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method, comprising:
-
receiving, at a headphone assembly wearable on the head of a person, first wireless signals from a first antenna; receiving, at the headphone assembly, second wireless signals from a second antenna; and at the headphone assembly, employing at least one antenna selection procedure, wherein the first antenna has a first nulling direction and the second antenna has a second nulling direction different from the first. - View Dependent Claims (17, 19)
