Summary
Piezoelectric transducers generate and receive acoustic signals in applications that range from small speakers to medical devices and sonar arrays. The trend to miniaturize these devices presents significant challenges. For example:
- Piezoelectric devices within mobile speaker applications need to be able to generate high-quality sound.
- Many noninvasive medical diagnostic devices operate at highly specific frequencies. Thus, the piezoelectric devices must operate at a precise frequency.
- Sonar applications often require that piezoelectric devices generate high-power signals to propagate long distances without attenuating below detectable levels.
In each case, product design engineers must develop designs that meet the required specifications within ever-smaller packages.
These electroacoustic transducers are inherently multiphysics in nature. Thus, designers must have a platform that allows them to calculate the multiple physics within their products, such as multiphysics simulation.
Multiphysics simulation has the features needed for developing product designs more effectively and simulating the designs within operating conditions. In addition, the simulations may include the entire ecosystem, from the control circuit to the piezoelectric transducer to the surrounding acoustic environment.
In this presentation, guest speakers Kyle Koppenhoefer and Joshua Thomas from AltaSim Technologies will discuss the development of an acoustic device that operates on piezoelectric transducers within an underwater environment. The webinar will also include a live demonstration using the COMSOL Multiphysics® software, as well as a Q&A session.
