High frequency curved surface longitudinal vibration transducer in assembling process due to piezoelectric ceramic piece the problems such as caused by frequency less than design
Value；Further, since the factors such as variation of front/rear cover plank matter, it is lower than design value to also result in its resonant frequency measured value.Piezoelectricity
Potsherd, the material of forward and backward cover board and length etc. are an important factor for influencing high-frequency transducer resonant frequency, to select unlike material
Front shroud and back shroud, and selection different length cover board, the equivalent mass of entire energy converter can be adjusted, so as to adjust
Resonant frequency.
For the longitudinal vibrator assembled, piezoelectric ceramic piece, forward and backward cover board material it has been determined that and back shroud by
It, cannot be to its working process in having been inserted into the reasons such as shell, close electrode lead-out area.In this case, processing method
There are two types of：First, it is allowed to scrap, manpower, financial resources and material resources are wasted in this way, it is infeasible；Second is that passing through turning, milling, grinding etc.
Manufacturing process reduces the effective mass of front shroud, improves high frequency curved surface longitudinal vibration transducer frequency.
It is arc since high frequency curved surface longitudinal vibration transducer needs the face of working process, discomfort shares grinding side
Formula, and turning and milling may add a big torque in energy converter self structure, cause to apply on longitudinal vibrator
Prestressed failure, reduce high frequency curved surface longitudinal vibration transducer comprehensive performance.In addition, in engineering, even planar transducer base
Battle array is also due to the factors such as machining accuracy and assembling quality, cause plane less smooth, and high frequency longitudinal vibration transducer resonant frequency
Very sensitive to the quality of front shroud, sensitivity is reinforced with the rising of frequency, such as accumulation difference in height to 0.1mm,
Difference under 100Khz frequencies can reach 400hz or so.It can make longitudinal vibration transducer using manufacturing process such as turning, milling, grindings
Frequency departure is larger, reduces sound source level.
