Abstract:
A personal audio system enabling a user to distinguish approximate locations of sound sources comprises at least one sound receiver. The sound receiver comprises a sound collecting structure for collecting sound. The sound collecting structure comprises a plurality of sound passages opening toward different directions and with different sizes to collect sound waves from the environment. The different sizes of the openings render a decline or an increase in specific frequency ranges of sound as a result of different resonances via the different openings. The user may therefore distinguish the direction of a sound source based on the slightly different pitches (frequencies) of the sound.

Claim (Index 13):
A personal audio system for a user to distinguish locations of sound sources, comprising:\n a left sound receiver and a right sound receiver; a left sound delivery device and a right sound delivery device configured for generating sound according to electronic signals; and a connecting unit configured to electrically connect the right sound receiver to the right sound delivery device and to electrically connect the left sound receiver to the left sound delivery device, wherein each of the left sound receiver and the right sound receiver comprises a sound collecting structure for collecting the sound and a microphone for converting the sound to the electronic signals, the sound collecting structure comprises:\n at least one first opening located at a first outer surface of the sound collecting structure, the at least one first opening comprising a first section at the first outer surface; \n at least one second opening located at a second outer surface of the sound collecting structure, the at least one second opening comprising a second section at the second outer surface, the first outer surface and the second outer surface substantially facing opposite directions, and a diameter of the first section being different from a diameter of the second section; \n a sound passage located inside the sound collecting structure, the at least one first opening being in communication with the at least one second opening through the sound passage; and \n a third opening located at a peripheral surface of the sound collecting structure and being in communication with the sound passage, and the microphone being configured to receive the sound from the third opening.
