Abstract
Head-worn computers include a front frame mechanically adapted to secure a see-through computer display and an arm, secured to the front frame, mechanically adapted to secure the front frame to a head of a user. The arm includes an internal speaker system, enclosed by the arm, wherein the internal speaker system comprises a speaker having a first side and an opposing second side and a first cavity positioned along the first side of the speaker, the arm further comprising a vent positioned to vent the first cavity and a second cavity positioned along the second side of the speaker.
Claims20
A wearable head device, comprising:
- a front frame;
- a see-through display coupled to the front frame;
- and
- an arm coupled to the front frame and configured to attach the wearable head device to a user's head,
- wherein:
- the arm houses a first internal speaker system and comprises a vent;
- the first internal speaker system comprises:
- a speaker configured to project sound in a first direction,
- a first cavity including:
- a proximate cavity positioned adjacent to the speaker and in a second direction from the speaker, the second direction opposite the first direction, and
- a distal cavity acoustically coupled to the proximate cavity, and
- a second cavity positioned adjacent to the speaker and in the first direction from the speaker;
- the vent is positioned to place the proximate cavity of the first cavity in air communication with the distal cavity of the first cavity, such that the proximate and distal cavities of the first cavity are acoustically coupled;
- and
- the proximate cavity of the first cavity is coupled to an outside environment.
A wearable head device, comprising:
- a front frame;
- a see-through display coupled to the frame;
- and
- an arm coupled to the front frame and configured to attach the wearable head device to a user's head,
- wherein:
- the front frame houses a first internal speaker system and comprises a vent;
- the first internal speaker system comprises:
- a speaker configured to project sound in a first direction,
- a first cavity including:
- a proximate cavity positioned adjacent to the speaker and in a second direction from the speaker, the second direction opposite the first direction, and
- a distal cavity acoustically coupled to the proximate cavity, and
- a second cavity positioned adjacent to the speaker and in the first direction from the speaker;
- the vent is positioned to place the proximate cavity of the first cavity in air communication with the distal cavity of the first cavity, such that the proximate and distal cavities of the first cavity are acoustically coupled;
- and
- the proximate cavity of the first cavity is coupled to an outside environment.
