Stand-alone multifunctional earphone for sports activities

A system with two apparatuses, each apparatus comprising:

• a housing configured to be carried in an ear,
• a motion sensor unit configured to detect motion data, wherein the motion sensor unit is comprised of at least one accelerometer;
• a physiological sensor unit configured to detect physiological data, wherein the physiological sensor comprises at least one pulse oximeter;
• a data processing unit configured to receive motion data from the motion sensor unit and physiological data from the physiological sensor unit and generate performance data based on the motion data and the physiological data, wherein the data processing unit is operatively connected to the motion sensor unit and the physiological sensor unit;
• a signal processing unit operatively connected to the data processing unit configured to generate a binaural audio signal with a first component at a first location in 3D space relative to a user of the apparatus based on the performance data and a second component at a second location in 3D space relative to the user based on the performance data, wherein the performance data is selected from a set comprising distance, speed, respiratory rate, oxygen saturation, heart rate, pace, and number of steps;
• and
• a loudspeaker for outputting the generated binaural audio signal at the first location and the second location;
• wherein the motion sensor unit, the physiological sensor unit, the loudspeaker, the data processing unit, and the signal processing unit are incorporated into the housing;
• wherein the generated performance data comprises a first parameter value and a second parameter value;
• wherein the first component of the binaural audio signal is based on at least one of the first parameter value and the second parameter value of the generated performance data;
• wherein the position of at least one of the first and second components of the binaural audio signal changes positions in the three dimensional space when at least one of the first parameter value and the second parameter value of the generated performance data changes.
