Ultrasonic transducer is a component that utilize the piezoelectricity for actualize
electroacoustic conversion. jydsonic ultrasonic cleaning transducer
are used where powerful ultrasonic wave must be generated, such as
in cleaning equipment and easy to instal. These transducers are
mounted into a structure that can be bolted almost anywhere.
Transducer requirements will depend on the application. Many
requirements will conflict with one another and will be given
different priorities. Hence, no single set of guidelines can
encompass all requirements — i.e., there are many different ways to
achieve the same objectives.
Analytically, transducer performance can only be predicted in a
general way. This is because the properties of piezoelectric
ceramics are often highly dependent on the operating conditions
including temperature, electrical field strength, static
compressive prestress, dynamic stress, number of load cycles, and
time. These operating conditions can interact with each other and
the effects of these conditions are often nonlinear. Also, many
properties of piezoelectric ceramics are orthotropic and can vary
among the individual ceramics and also between ceramic lots.
Further, the interactions at the various component interfaces
(e.g., at threads) may be difficult to characterize and the
coefficient of convective heat transfer for air cooling may only be
approximately estimated. Hence, much of the design process involves
The transducer converts high-frequency electrical energy into
high-frequency mechanical vibrations. And it contains several
piezoelectric ceramic discs sandwiched under pressure between two
metal blocks. Between each disc is a thin metal plate, which forms
the electrode. When a sinusoidal electrical signal is fed to the
transducer via the electrodes, the discs expand and contract,
producing axial vibrations.
• Converter: converters the electrical signal into a mechanical
• Booster: modifies the amplitude of the vibration. It is also used
in standard systems to clamp the stack in the press.
• Sonotrode: applies the mechanical vibration to the parts to be
