Abstract: A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

Abstract: Various embodiments of the present disclosure are directed towards an integrated circuit (IC) chip in which a pad barrier layer caps a pad of a piezoelectric device. The pad barrier layer is configured to block hydrogen ions and/or other errant materials from diffusing to the piezoelectric layer. Absent the pad barrier layer, hydrogen ions from hydrogen-ion containing processes performed after forming the pad may diffuse to the piezoelectric layer along a via extending from the pad to the piezoelectric device. By blocking diffusion of hydrogen ions and/or other errant materials to the piezoelectric device, the pad barrier layer may prevent delamination and breakdown of the piezoelectric layer. Hence, the pad barrier layer may prevent failure of the piezoelectric device.
