wherein the first side strap and the second side strap individually define an arcuate shape extending upward relative to the forehead assembly to curve around an individual ear of a user.
2. The head-mounted device of claim 1 , wherein the forehead assembly further comprises one or more physical processors housed within the forehead body, the one or more physical processors being configured by machine-readable instructions to send individual audio signals to individual ones of the first speaker, the second speaker, the third speaker, and the fourth speaker.
3. The head-mounted device of claim 2 , wherein the one or more physical processors further configured by machine-readable instructions to assign the individual audio signals to individual speakers, the assignment providing a surround sound effect.
4. The head-mounted device of claim 3 , wherein the surround sound effect includes a 5.1-surround sound.
5. The head-mounted device of claim 1 , wherein the first side strap and the second side strap individually include an arcuate shape portion configured for positioning above an individual ear of a user.
6. The head-mounted device of claim 5 , wherein the first volume and the second volume are individually positioned in the individual arcuate shape portions of the first side strap and the second side strap, such that the first volume and the second volume are positioned above the respective ears of the user wearing the head-mounted device.
7. The head-mounted device of claim 1 , wherein respective surfaces of the first speaker and the second speaker are arranged in a rearward direction opposite the forward direction at an angle with respect to one another.
8. The head-mounted device of claim 1 , wherein the forehead assembly further comprises a visor extending in a first direction from the forehead body, the visor being configured to guide audio outputted from the first speaker and the second speaker toward ears of a user.
9. The head-mounted device of claim 1 , wherein the forehead assembly further comprises:
an optical engine housed within the forehead body; and
a visor extending downward from the forehead body;
wherein the optical engine is configured to provide an image or a partial image reflected or displayed on the visor.
10. The head-mounted device of claim 1 , further comprising a top strap positioned between the first side strap and the second side strap and connecting the forehead assembly to the rear-head assembly.
11. The head-mounted device of claim 1 , further comprising a microphone system, the microphone system comprising first, second, and third microphones disposed on the forehead body, the first microphone spaced from the second microphone by a first distance, and the second microphone spaced from the third microphone by a second distance greater than the first distance.
12. The head-mounted device of claim 1 , further comprising a visor disposed on the forehead body, the visor configured to guide sound waves emitted by the first speaker and the second speaker in a rearward direction opposite of the forward direction.
13. The head-mounted device of claim 12 , wherein the first speaker and the second speaker are arranged to face the rearward direction at a first angle with respect to one another and a second angle with respect to the corresponding speaker.
14. The head-mounted device of claim 1 , further comprising a buckle configured to receive and releasably attach to the first strap and the second strap.
15. The head-mounted device of claim 1 , wherein the first speaker and the second speaker are symmetrically arranged about a longitudinal axis of the forehead body.
16. The head-mounted device of claim 1 , wherein the forehead body further includes an inner enclosure, wherein the first speaker and the second speaker are housed within the inner enclosure.
17. The head-mounted device of claim 1 , further comprising a forehead support, the forehead support being configured to provide an interface between the forehead body and a user's forehead.
18. The head-mounted device of claim 1 , wherein the image or the partial image reflected or displayed on the visor provides defines a virtual reality or an augmented reality environment.
19. The head-mounted device of claim 1 , wherein one both of the first speaker and/or the second speaker provide a higher decibel output than one or both of the third speaker and/or the fourth speaker.
