Abstract
Phase plugs (70) and related audio devices (100, 105) and methods comprise various compression members (2), and guides (120) extending from the compression members (2) to tips (84), are configured such that central axes (93, 99) defined perpendicular to compression members (2) and/or diaphragms (94) are asymmetric and/or non-axisymmetric to the central axes (93, 99).
Claims30
A phase plug (70) comprising:
- a compression member (2);
- and
- a guide (120) extending from the compression member (2) to a tip (84) and configured such that the guide (120) is non-axisymmetric to a central axis (93) defined perpendicular to the compression member (2).
An audio device (100) comprising:
- a housing (101) having a first acoustic opening (60);
- a transducer assembly (90) disposed in the housing (101) such that the transducer assembly (90) is located distal to the first acoustic opening (60);
- and
- a phase plug (70) disposed within the housing (101) between the transducer assembly (90) and the first acoustic opening (60), such that the phase plug (70) is asymmetric.

An in-ear audio device (105) comprising:
- a hollow sound port (17) formed to fit within an ear canal, the hollow sound port (17) having
- a first opening (50) directed away from the ear canal, and
- a second opening (60) directed toward the ear canal;
- a transducer assembly (90) disposed at the first opening (50);
- and
- a phase-shift plug (70) disposed within the hollow sound port (17) between the transducer assembly (90) and the second opening (60), such that the phase-shift plug (70) is formed asymmetrically to fit within the hollow sound port (17).
3 more elements
A method for generating sound, comprising the steps of:
- compressing and decompressing air at an audio frequency between a transducer diaphragm (94) and a phase plug compression member (2) such that sound waves are produced;
- guiding the sound waves through a waveguide (85) formed by a non-axisymmetric phase plug (70);
- converging the sound waves at a coherence tip (84) of the waveguide (85);
- and
- emitting the sound waves through an acoustic opening (60), such that the sound waves emit substantially in phase.
