Abstract
A mouthpiece includes a body, a piezoelectric sensor, and a support structure. The body defines a conduit for air. The piezoelectric sensor includes a piezoelectric element having a porous layer compressable and deformable by vibration of the air. The piezoelectric sensor is configured to generate a detection signal based on compression and deformation of the porous layer. The support structure supports the piezoelectric element in the conduit.
