Abstract
Integrating speakers into small-size devices is difficult. This is especially challenging for smart glasses, augmented/virtual reality (AR/VR) headsets, or similar devices due to the compactness of the arm or temple portion of the glasses or headsets. This disclosure describes techniques that leverage the piezoelectric effect to generate high-quality audio using components that can fit into the compact form factor of smart glasses. Smart glasses and VR headsets have glass or plastic lenses, which advantageously present an ample area for piezoelectric elements (crystals) to be affixed upon. When electrically excited, the piezoelectric elements cause the lenses to imperceptibly vibrate in synchronism with the electrical excitation. The vibrations are perceived by the wearer of the smart glasses as audio.
