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.
Claims7
A wireless headphone, comprising:
- a body configured to fit onto a user's head, the body defining opposed first and second ends;
- a first speaker coupled to a first speaker mount on the first end of the body;
