Driving circuit for piezoelectric body
专利汇可以提供Driving circuit for piezoelectric body专利检索，专利查询，专利分析的服务。并且PURPOSE:To suppress mechanical vibrations of a piezoelectric body easily with simple constitution by using a resistance, provided between the input side of the piezoelectric body and the amplifying circuit of a driving circuit, as a load of reverse piezoeletric effect and by extracting only a signal relative to the mechanical vibrations from a signal from the resistance and negatively feeding it back. CONSTITUTION:From a piezoelectric body 33 fitted to the video head of a video tape recorder, a signal containing a matching state between the head and a recording track is obtained and applied to the input terminal 30 of a piezoelectric-body driving circuit. This signal passed through a driving and amplifying circuit 32 is inputted to one terminal of a differential amplifying circuit 37 through a resistance 34 as a load for a reverse piezoelectric effect signal. An output signal branched from the circuit 32 passes through a resistance 35 and a capacitor 36 to eliminate components other than a signal component relating to mechanical vibrations, and the resulting signal is inputted to the other terminal of the circuit 37. Therefore, only the signal relating to the unnecessary mechanical vibrations of the piezoelectric body 33 is outputted to the circuit 37 and this signal is negatively fed back through a phase correcting circuit 38 and a subtracting circuit 31 to suppress the mechanical vibrations with the simple circuit constitution.，下面是Driving circuit for piezoelectric body专利的具体信息内容。
