6. The apparatus of claim 1 , wherein the sliding member and the protrusion member are located on a portion of the HMD unit that is positioned against a side of a user's head.

7. The apparatus of claim 1 , wherein the sliding member comprises a plurality of bone conduction speakers along a length of the sliding member that are configured to be selectively turned on and off.

8. The apparatus of claim 7 , wherein the each of the plurality of bone conduction speakers are selectively turned on in response to pressure detected from pressure sensors in the sliding member that correspond to the plurality of bone conduction speakers sensing a pressure that satisfies a threshold pressure.

9. The apparatus of claim 1 , wherein:

the protrusion member further comprises at least one a proximity sensor; and

the protrusion member is automatically adjusted along the second axis until a proximity that the at least one proximity sensor senses satisfying satisfies a proximity threshold.

10. An apparatus, comprising:

a securing member of a head-mounted display (“HMD”) unit configured to secure the HMD unit to a user's head;

a sliding member coupled to the securing member and comprising at least one bone conduction speaker, the sliding member adjustable along a first axis to position the bone conduction speaker along the first axis;

a protrusion member coupled to the sliding member and housing the at least one bone conduction speaker, the protrusion member adjustable along a second axis, substantially perpendicular to the first axis, to position the bone conduction speaker along the second axis; and

at least one pressure sensor, wherein the at least one bone conduction speaker is activated in response to pressure detected from the at least one pressure sensor satisfying a predefined pressure threshold.

11. The apparatus of claim 10 , wherein the at least one bone conduction speaker is located near the at least one pressure sensor on the securing member.

12. The apparatus of claim 10 , wherein the sliding member and the protrusion member are located on the securing member at a location that is positioned against a side of a user's head.

13. The apparatus of claim 10 , wherein the sliding member further comprises a locking member configured to lock the sliding member in position along the first axis.

14. The apparatus of claim 13 , wherein the position is one of a plurality of predefined positions located along the first axis.

15. The apparatus of claim 10 , wherein the protrusion member is adjustable using an adjustment mechanism to increase or decrease a height of the protrusion member along the second axis.

16. The apparatus of claim 15 , wherein the adjustment member comprises a pinwheel member that is rotatable to increase or decrease the height of the protrusion member along the second axis.

17. The apparatus of claim 10 , wherein:

the protrusion member further comprises at least proximity sensor; and

the protrusion member is automatically adjusted along the second axis until a proximity that the at least one proximity sensor senses satisfies a proximity threshold.

18. A system, comprising:

a head mounted display (“HMD”) unit comprising at least one display;

a securing member of the HMD unit configured to secure the HMD unit to a user's head;

a sliding member coupled to the securing member and comprising at least one bone conduction speaker, the sliding member adjustable along a first axis to position the bone conduction speaker along the first axis;

a protrusion member coupled to the sliding member and housing the at least one bone conduction speaker, the protrusion member adjustable along a second axis, substantially perpendicular to the first axis, to position the bone conduction speaker along the second axis; and

at least one pressure sensor, wherein the at least one bone conduction speaker is activated in response to pressure detected from the at least one pressure sensor satisfying a predefined pressure threshold.

19. The system of claim 18 , wherein the sliding member and/or the protrusion member are adjustable via one or more digital controls of an interface of the HMD unit.
