`
`ABSTRACT
`
`A wearable wireless audio device includes a support, an
`electronics circuit, and a speaker. The support includesa first
`ear stem and anorbital, 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 towardat 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 speakeris configured to rotate from a
`first position in which the speaker face is substantially
`parallel to a yz-plane to a second position im which the
`speakeris inclined at an angle with respectto 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.

`
`[0001] The present application is a continuation-in-part of
`US. patent application Ser. No. 10/628,831, filed Jul. 28,
`2003, which claimspriority benefit under 35 U.S.C. § 119(e)
`from U.S. Provisional Application Nos. 60/399,317, filed
`Jul. 26, 2002 and 60/460,154,filed Apr. 3, 2003, and which
`is a continuation-in-part of U.S. patent application Ser. No.
`10/004,543, filed Dec. 4, 2001, pending, which is a continu-
`ation of U.S. patent application Ser. No. 09/585,593, filed
`Jun. 2, 2000, now U.S. Pat. No. 6,325,507, and the present
`application claimspriority benefit under 35 U.S.C. § 120 to
`the same. Moreover,the present application incorporatesall
`of the foregoing disclosures herein byreference.
`
`[0002]
`
`[0004]
`
`
`
`
`
`into
`ears, and is configured to convert the audio signal
`sound. The speaker generally includes a speaker face, and is
`configuredto rotate from a first position in whichthe speaker
`face is substantially parallel
`to a yz-plane to a second
`position in which the speaker is substantially parallel to an
`xz-plane. In another embodiment,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 inclined at an angle with respect to the
`yz-plane. In one embodiment, the angle is between about
`300 and about 90°.
`
`In another embodiment, the speaker is configured
`[0008]
`to rotate along an arcuate path about an axis substantially
`parallel
`to an x-axis from a first position in which the
`speaker face is substantially parallel
`to a yz-plane to a
`second position in which the speaker remains substantially
`parallel to the yz-plane, and wherein the speakeris config-
`ured to move an adjustmentdistance in a direction substan-
`tially parallel to a z-axis as a result of said rotation. In one
`embodiment, the adjustmentdistance is about 3 cm.
`
`In yet another embodiment, the speaker includes a
`[0009]
`speaker face, and the speaker is coupled to the support with
`a speakerpivot, and the speaker is configuredto rotate about
`the speaker pivot while maintaining the speaker face sub-
`stantially parallel to a yz-plane. In another embodiment, the
`speaker is configured to move along an axis substantially
`parallel to a z-axis with respect to the support.
`
`In one embodiment, the digital audio file is com-
`[0010]
`pressed, and may be an MP3 formatted file. In another
`embodiment, the support includes a channel and a conduc-
`tor, wherein the channel extends along atleast a portion of
`the ear stem, and the conductoris located at least partially
`within the channel.
`
`the wearable wireless
`In another embodiment,
`[0011]
`audio device further includes a second ear stem, the elec-
`tronics circuit comprises a memorycircuit and a processor,
`and the memorycircuit is carried by thefirst ear stem, and
`the memorycircuit is carried by the second earstem. In one
`embodiment,
`the wearable wireless audio device also
`includes a second ear stem, wherein the electronics circuit
`comprises a battery and a processor, and wherein the battery
`is carried by the first ear stem, and the memory circuit is
`carried by the second ear stem. In another embodiment, the
`electronics componentsare distributed between the first and
`second ear stems. In yet another embodiment, the wearable
`wireless audio device includesa nose bridge, whereindigital
`signals generated by the electronics circuit are transmitted
`across the nose bridge.
`
`the wearable wireless
`In another embodiment,
`[0012]
`audio device includes a data port, wherein the data port is
`carried by the ear stem. The data port may beselected from
`the group comprising: a mini-USB connector, a FIREWIRE
`connector, an IEEE 1394 cable connector, an RS232 con-
`nector, a JTAB connector, an antenna, a wireless receiver, a
`radio, an RF receiver, and a BLUETOOTH receiver. In
`another embodiment, the wearable wireless audio device is
`removably connectable to a computing device. The wearable

`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`2. Description of the Related Art
`
`[0003] The present inventionis directed to wearable audio
`devices, and in particular, devices that humans can wear on
`heir heads.
`
`In the portable audio playback industry, certain
`[0005]
`devices for remote audio listening have become more popu-
`lar. Certain companies have begun to widely distribute
`portable audio playback devices, such as MP3 players,
`which allowa user to listen to audiofiles with the use of
`
`headphones. For example, a user can wear a headset having
`speakers connected by a flexible cable to an MP3 player,
`which can be worn onthe belt. However, with such headsets,
`whenever a user wants to wear glasses or sunglasses, they
`must adjust or remove the headset from their ears. Further,
`it 1s often quite uncomfortable to wear both a headset and a
`pair of sunglasses at the same time. Such discomfort, when
`applied for a long period of time, can cause muscular pain
`and/or headaches. In addition, the flexible cable extending
`from the MP3player to the headphonescan limit mobility of
`he wearer; particularly those participating in sporting activi-
`ies.
`

`joint coupled to the second end. The first moveable joint
`provides rotation about a first rotation axis and the second
`moveable joint provides rotation about a second rotation
`axis. The first rotation axis and the second rotation axis are
`substantially perpendicular to one another. The electronics
`circuit
