Circuit works: When you clapping sound through the piezoelectric ceramic HTD people seized converted into an electrical

signal fed to the transistor VT1 after amplification, through the coupling capacitor C1 to the base of the electrical path 555 2 feet, 3 feet high output power of 555 level. In this case the VT2, VT3, T, B, called oscillator consisting of cats began to give power to make T, speaker B issued meow sound.
