a piezo beam device mounted to the first temple arm of the eyeglass frame, the piezo beam device configured to excite vibration in a pinna of an ear of a wearer of the pair of eyeglasses; and
a controller mounted to the eyeglass frame, the controller configured to receive an audio signal and to control the piezo beam device, the control to excite vibration in the pinna of the ear of the wearer to generate audio corresponding to the audio signal.
2 . The pair of eyeglasses as described in claim 1 , further comprising an additional piezo beam device mounted to the second temple arm of the eyeglass frame, the additional piezo beam device configured to excite vibration in an other pinna of an other ear of the wearer of the pair of eyeglasses.
3 . The pair of eyeglasses as described in claim 2 , wherein the controller is configured to control the piezo beam device and the additional piezo beam device to generate the same audio for the ear and the other ear of the wearer of the pair of eyeglasses.
4 . The pair of eyeglasses as described in claim 2 , wherein the controller is configured to control the piezo beam device and the additional piezo beam device to generate stereo audio for the ear and the other ear of the wearer of the pair of eyeglasses.
5 . The pair of eyeglasses as described in claim 1 , wherein the piezo beam device is configured to be adjusted by sliding the piezo beam device along the first temple arm of the eyeglass frame to cause a contact area of the piezo beam device to contact the pinna of the ear of the wearer.
6 . The pair of eyeglasses as described in claim 1 , wherein the piezo beam device is configured to be adjusted by sliding the piezo beam device along the first temple arm of the eyeglass frame to cause a contact area of the piezo beam device to contact a top portion of a rear face of the pinna of the ear of the wearer.
7 . The pair of eyeglasses as described in claim 1 , wherein the piezo beam device is configured to be adjusted by sliding the piezo beam device along the first temple arm of the eyeglass frame to cause a contact area of the piezo beam device to contact a middle portion of a rear face of the pinna of the ear of the wearer.
8 . The pair of eyeglasses as described in claim 1 , wherein the piezo beam device is configured to excite vibration in the pinna of the ear of the wearer to generate the audio without occluding the ear of the wearer.
9 . The pair of eyeglasses as described in claim 1 , wherein the audio signal is associated with an augmented reality application, and wherein the controller is configured to control the piezo beam device to excite vibration in the pinna of the ear of the wearer to generate the audio corresponding to the audio signal that is mixed with additional audio from a real-world environment of the wearer.
10 . The pair of eyeglasses as described in claim 1 , further comprising a display device mounted to the eyeglass frame, wherein the controller is further configured to receive a video signal that is associated with the audio signal, and to control the display device to generate a virtual image corresponding to the video signal.
11 . A method comprising:
receiving an audio signal from a source device; and
controlling a piezo beam device to excite vibration in a pinna of an ear of a listener to generate audio corresponding to the audio signal for the ear of the listener.
12 . The method as described in claim 11 , wherein the piezo beam device and the source device are mounted to a pair of eyeglasses.
13 . The method as described in claim 11 , wherein the piezo beam device is mounted to a pair of eyeglasses, and wherein the source device is located remote from the pair of eyeglasses and communicatively coupled to the piezo beam device via a wired or wireless connection.
14 . The method as described in claim 11 , further comprising controlling an additional piezo beam device to excite vibration in an other pinna of an other ear of the listener to generate audio corresponding to the audio signal for the other ear of the listener.
15 . The method as described in claim 11 , wherein the audio signal is associated with an augmented reality application.
16 . The method as described in claim 15 , wherein the controlling further comprises controlling the piezo beam device to excite vibration in the pinna of the ear of the listener to generate audio corresponding to the audio signal associated with the augmented reality application, the audio mixed with audio from a real-world environment of the listener.
17 . The method as described in claim 11 , wherein the piezo beam device is mounted to a pair of eyeglasses having a display device, and further comprising:
receiving a video signal that is associated with the audio signal from the source device; and
controlling the display device to generate a virtual image corresponding to the video signal for the listener.
18 . A piezo beam device comprising:
an adjustable mount configured to mount the piezo beam device to a temple arm of a pair of eyeglasses and to enable the piezo beam device to be adjusted by sliding the piezo beam device along the temple arm of the pair of eyeglasses to place a contact area of the piezo beam device in contact with a pinna of an ear of a wearer of the pair of eyeglasses; and
a controller configured to control the piezo beam device to excite vibration in the pinna of the wearer of the pair of eyeglasses, the vibration causing the audio to be generated for the wearer when the contact area of the piezo beam device is placed in contact with the pinna of the ear of the wearer.
19 . The piezo beam device as recited in claim 18 , wherein the contact area is positioned on a lower face of the adjustable mount and is configured to contact a top portion of a rear face of the pinna of the wearer.
20 . The piezo beam device as recited in claim 18 , wherein the adjustable mount includes a top section and a bottom section that is perpendicular to the top section, wherein the top section of the adjustable mount is configured to slide along the temple arm of the pair of eyeglasses, and wherein the contact area is positioned on the bottom section of the adjustable mount and is configured to contact a middle portion of a rear face of the pinna of the ear of the wearer.
