Wireless audio streaming system for swimmers and under water applications
A wireless audio streaming system for swimmers and underwater applications uses directional transmission antennas, one or more reception antennas worn on a user, and a combination of radio frequency and near-field magnetic induction communication, for streaming audio to a swimmer, buffering the streamed audio, and allowing the user to play the audio on a wireless, waterproof headset.
1. A wireless audio streaming system for streaming digital audio to a wireless headset in an aquatic environment, the system comprising:
a media player that generates and plays a digital media stream; and
a directional antenna that is communicatively coupled with the media player to receive the played digital media stream, the directional antenna including a tracking mechanism configured to track a position of the wireless headset and a beamformer configured for providing a radiation pattern according to the position of the wireless headset in the aquatic environment to transmit the played digital media stream via the radiation pattern to the wireless headset at the position within the aquatic environment.
2. The wireless audio streaming system in accordance with claim 1 , wherein the directional antenna is communicatively coupled to the media player via a wireless interface.
3. The wireless audio streaming system in accordance with claim 1 , wherein the directional antenna is communicatively coupled to the media player via a wired interface.
4. The wireless audio streaming system in accordance with claim 2 , wherein the wireless interface includes inductive coupling via near field magnetic induction (NFMI).
5. The wireless audio streaming system in accordance with claim 3 , wherein the media player includes a hard-wired audio output, and wherein the wired interface includes a connection between the directional antenna and the hard-wired audio output of the media player.
6. The wireless audio streaming system in accordance with claim 1 , further comprising a case that receives both the media player and the directional antenna, the case positioning the media player in proximity to the directional antenna to facilitate communicatively coupling the directional antenna with the media player.
7. The wireless audio streaming system in accordance with claim 6 , wherein the case encloses both the media player and the directional antenna.
8. The wireless audio streaming system in accordance with claim 7 , wherein the case is waterproof.
9. The wireless audio streaming system in accordance with claim 6 , wherein the case includes a stand that orients the case to facilitate the directional antenna providing the radiation pattern that is tailored for the aquatic environment.
10. The wireless audio streaming system in accordance with claim 6 , wherein the directional antenna is integrated with the case.
