Abstract

There is a vibration speaker device called an audio exciter. The potential of the exciter as a vibration device was investigated by conducting experiments on a single steel plate and comparing the results with the impact test method using an impulse hammer. The power spectrum results showed that the exciter was able to vibrate up to approximately 20 kHz, and it was shown that it was possible to predict the magnitude of the exciter's FRF from the impulse hammer FRF results. Furthermore, a comparison with the impulse hammer results showed that the ILF identification was qualitatively better.
