Abstract
An audio device with a structure such as an acoustic waveguide, and first and second spaced acoustic transducers that are carried by the structure. A controller is adapted to change the location of the dominant sound source produced by the transducers together in the far field. The device can also be used in a method of facilitating speech communication between two people who speak different languages.
Claims24
An audio device, comprising:
- a structure that is adapted to be worn by a person;
- two spaced acoustic transducers that each project sound and are carried by the structure;
- and
- a controller that is adapted to change a location of a dominant sound source produced by the two transducers together in a far field, wherein the controller is adapted to change the relative phases of the two transducers.
1 more element
An audio device, comprising:
- an acoustic waveguide with first and second ends and a port tube located approximately equidistantly from the ends and having an outlet;
- a neck loop that is constructed and arranged to be worn around the neck, wherein the waveguide is located at least in part within the neck loop;
- first and second acoustic transducers, wherein the first acoustic transducer is acoustically coupled to the waveguide proximate the first end, and the second acoustic transducer is acoustically coupled to the waveguide proximate the second end, and wherein the first and second acoustic transducers are each further arranged to project sound outwardly from the waveguide;
- and
- a controller that controls the relative phases of the first and second acoustic transducers.
