A wearable wireless audio device includes a support, an electronics
circuit, and a speaker. The support includes a first ear stem and an
orbital, and is configured to support at least one lens in a wearer's
field of view. The electronics circuit is supported by the support and is
configured to receive at least one digital audio file and generate an
audio signal indicative of the at least one digital audio file. The
speaker is supported by the support, and is directed toward at least one
of the wearer's ears. The speaker is configured to convert the audio
signal into sound. The speaker has a speaker face, and the speaker is
configured to rotate from a first position in which the speaker face is
substantially parallel to a yz-plane to a second position in which the
speaker is inclined at an angle with respect to the yz-plane. The speaker
is coupled to the support with a speaker pivot, and is configured to
rotate about the speaker pivot while maintaining the speaker face
substantially parallel to a yz-plane. The speaker is configured to move
along an axis substantially parallel to a z-axis with respect to the
support.
