Abstract
An acoustic device that has a neck loop that is constructed and arranged to be worn around the neck. The neck loop includes a housing with a first acoustic waveguide having a first sound outlet opening, and a second acoustic waveguide having a second sound outlet opening. There is a first open-backed acoustic driver acoustically coupled to the first waveguide and a second open-backed acoustic driver acoustically coupled to the second waveguide.
Claims23
An acoustic device, comprising:
- a neck loop that is constructed and arranged to be worn around the neck, the neck loop comprising a first acoustic waveguide having a first sound outlet opening, and a second acoustic waveguide having a second sound outlet opening;
- a first open-backed acoustic driver acoustically coupled to the first waveguide;
- a second open-backed acoustic driver acoustically coupled to the second waveguide;
- a first pressure damping element acoustically coupled to the first waveguide, where the first pressure damping element is constructed and arranged to damp one or more acoustic resonances in the first waveguide;
- and
- a second pressure damping element acoustically coupled to the second waveguide, where the second pressure damping element is constructed and arranged to damp one or more acoustic resonances in the second waveguide.

An acoustic device, comprising:
- a neck loop that is constructed and arranged to be worn around the neck, the neck loop comprising a first acoustic waveguide having a first sound outlet opening, and a second acoustic waveguide having a second sound outlet opening, wherein the first and second waveguides are side-by-side in at least some of the neck loop;
- a first open-backed acoustic driver acoustically coupled to the first waveguide;
- a second open-backed acoustic driver acoustically coupled to the second waveguide;
- wherein each waveguide has a first end and its corresponding acoustic driver located at one side of the head and below the adjacent ear;
- wherein each waveguide has a second end that leads to its sound outlet opening, located at the other side of the head and below the other, adjacent ear;
- a first pressure damping element acoustically coupled to the first waveguide, where the first pressure damping element is constructed and arranged to damp one or more acoustic resonances in the first waveguide;
- and
- a second pressure damping element acoustically coupled to the second waveguide, where the second pressure damping element is constructed and arranged to damp one or more acoustic resonances in the second waveguide.
