Detachable audio system for head-mounted displays

A detachable coupling structure to detachably couple an audio system to a head-mounted display system, the detachable coupling structure comprising:

• a base;
• a plurality of posts, extending from the base, to couple to a strap of the head-mounted display, each post of the plurality of the posts comprising:
• a tip to be inserted into the strap, and
• a groove to engage with the strap;
• a spring, contacting the base, to detach the plurality of posts from the strap when the plurality of posts decouple from the strap;
• and
• a spacer through which the plurality of posts extend, wherein the spring contacts the spacer.

A head-mounted display system, the head-mounted display system comprising:

• a head-mounted display;
• a strap for mounting the head-mounted display on the user's head, the strap comprising first and second rigid segments coupled to a semi-rigid segment from first and second ends of the semi-rigid segment respectively, the semi-rigid segment to conform to a portion of the user's head;
• and
• an audio subsystem integrated with the head-mounted display, the audio subsystem comprising:
• a speaker;
• an arm coupled to the speaker;
• a strap connector including a first side coupled to the arm and a second side opposite to the first side;
• and
• a coupling subsystem to couple the strap connector of the audio subsystem to the first rigid segment of the strap, the coupling subsystem comprising:
• a base including a first side engaged with the second side of the strap connector and a second side opposite to the first side;
• a plurality of posts extending from the second side of the base to couple to the first rigid segment of the strap;
• a spacer through which the plurality of posts extend;
• and
• a spring, contacting the second side of the base and the spacer, to detach the coupling subsystem from the strap when the plurality of posts release from the first rigid segment of the strap.
