Speaker systems for head-worn computer systems

1. A wearable head device, comprising:

a front frame;

a display coupled to the front frame; and

an arm coupled to the front frame, the arm extending for a length from the front frame toward an ear of a user,

wherein:

the arm houses an internal speaker system and a battery compartment, and

the internal speaker system comprises:

a speaker configured to project sound in a first direction,

a first cavity positioned adjacent to the speaker and further positioned in the first direction from the speaker,

a vent configured to vent the first cavity to an outside environment,

a second cavity positioned adjacent to the speaker and further positioned in a second direction from the speaker, the second direction different from the first direction, the second cavity further positioned adjacent to at least a portion of the battery compartment,

a third cavity configured for fluid communication with the second cavity, and

a second vent configured to vent the second cavity via the third cavity to the outside environment.

2. The wearable head device of claim 1 , wherein the first cavity is configured to be positioned in front of a user's ear when the wearable head device is worn by the user.

3. The wearable head device of claim 1 , wherein the first cavity is configured to be positioned above a user's ear when the wearable head device is worn by the user.

4. The wearable head device of claim 1 , wherein the first cavity is configured to be positioned behind a user's ear when the wearable head device is worn by the user.

5. The wearable head device of claim 1 , wherein the first cavity comprises a first shape and the second cavity comprises a second shape different from the first shape.

6. The wearable head device of claim 1 , wherein the arm comprises a temple portion and an ear-horn.

7. The wearable head device of claim 6 , wherein the temple portion comprises the battery compartment and the internal speaker system.

8. The wearable head device of claim 7 , wherein:

the battery compartment is configured to rest a first distance from a user's ear when the wearable head device is worn by the user, and

the speaker is configured to rest a second distance from the user's ear when the wearable head device is worn by the user, the second distance less than the first distance.

9. The wearable head device of claim 6 , wherein the temple portion comprises the first cavity and further comprises the second cavity.

10. The wearable head device of claim 6 , wherein the ear-horn is configured to rest above a user's ear when the wearable head device is worn by the user.

11. The wearable head device of claim 6 , wherein the temple portion comprises a tubular portion.

12. The wearable head device of claim 11 , wherein the at least one of the first cavity and the second cavity is configured to traverse a length of the tubular portion.

13. The wearable device of claim 12 , wherein the battery compartment is included in the tubular portion.

14. The wearable head device of claim 1 , further comprising a second arm coupled to the front frame, the second arm housing a second internal speaker system.

15. The wearable head device of claim 1 , further comprising an audio connector configured to connect to an external speaker system.

16. The wearable head device of claim 1 , wherein the first direction is toward the ear of the user when the wearable head device is worn by the user.

17. The wearable head device of claim 1 , wherein the second direction is at an angle with respect to the front frame of the wearable head device.

18. The wearable head device of claim 1 , wherein the battery compartment is configured to receive a round battery.
