Abstract
Disclosed is a sound vibration sensor using a piezoelectric element having a cantilever structure. The sound vibration sensor includes a housing forming an exterior, a piezoelectric element having a cantilever structure installed in the housing, a support structure supporting a fixed end of the piezoelectric element, a weight attached to a free end of the piezoelectric element, and an energizing part configured to transmit an output from the piezoelectric element, wherein the sound vibration sensor comes into contact with a speaker's body, receives vibration of the body generated when the speaker utters a sound through the housing, and amplifies the vibration by the free end of the piezoelectric element to detect the voice vibration of the speaker using a piezoelectric characteristic of the piezoelectric element.
