Abstract
A communication headset includes a neckband with a horseshoe-shaped footprint and two microphone tips disposed at two ends of the neckband, the two ends establishing an aperture of the horseshoe-shaped footprint. Each of the two microphone tips includes a slanted base. The communication headset further includes a microphone array including two sets of microphones in a spatial configuration in which the two sets of microphones are disposed on the slanted bases of the two microphone tips. An effective acoustic spacing between the microphones in the microphone array is at least 15 mm.
Claims19
A communication headset comprising:
- a neckband with a horseshoe-shaped footprint, comprising surfaces extending along a length of the horseshoe-shaped footprint and having at least one width perpendicular to the length;
- two microphone tips disposed at two ends of the neckband, wherein each of the two microphone tips comprises a support structure having a slanted base, the support structure having a first side extending along the length, a second side extending along the at least one width, and a third side forming the slanted base, the slanted base forming a slant angle greater than ten degrees with the second side and being defined by the first side and the second side;
- and
- a microphone array comprising two sets of microphones in a spatial configuration in which the two sets of microphones are disposed on the slanted bases of the two microphone tips, and each comprising at least two microphones disposed at two endpoints of the slanted bases with an effective acoustic spacing of at least 15 mm between the at least two microphones.
A method for manufacturing a communication headset, the method comprising:
- manufacturing a neckband with a horseshoe-shaped footprint, comprising surfaces extending along a length of the horseshoe-shaped footprint and having at least one width perpendicular to the length;
- and
- appending two microphone tips disposed at two ends of the neckband, wherein each of the two microphone tips comprises a support structure having a slanted base, the support structure having a first side extending along the length, a second side extending along the at least one width, and a third side forming the slanted base, the slanted base forming a slant angle greater than ten degrees with the second side and being defined by the first side and the second side,
- wherein the two microphone tips comprise a microphone array comprising two sets of microphones in a spatial configuration in which the two sets of microphones are disposed on the slanted bases of the two microphone tips and each comprising at least two microphones disposed at two endpoints of the slanted bases with an effective acoustic spacing of at least 15 mm between the at least two microphones.
