Abstract
A head-mounted display (HMID) includes a strap arm that transmits audio. The HMID includes a front rigid body and a strap arm. The strap arm includes a body portion defining a boss having an aperture that rotatably connects the strap arm to the front rigid body. The body portion defines an audio passage to transmit sound and an audio port to output the sound. The audio passage is defined along the body portion between the aperture of the boss and the audio port. A speaker is positioned, such as within the aperture, to emit the sound through the audio passage and to the audio port. The strap arm can further include a back volume unit that enhances the sound transmitted through the audio passage.
