Decrement of piezoelectric constants in n-CdS crystals is observed as a function of conductivity. The decrement of the constants is closely related to the increment of the electrical conductivity with a one-valued function in a range between 10^<-8> and 10 ohm^<-1> cm^<-1>. For example, the piezoelectric constant in a CdS crystal with 10 ohm^<-1> cm^<-1> is only 40% of that with 10^<-8> ohm^<-1> cm^<-1>. This phenomenon is theoretically explained by the decrement of the effective charge on Cd or S ions caused by the Thomas-Fermi screening of conduction electrons in n-CdS crystals.
