Abstract
The present disclosure provides a method for obtaining a vibration transfer function from a sound generation unit to other positions. The method comprises: generating a first sound and a second sound based on a first test audio signal and a second test audio signal; outputting a first feedback signal after receiving the first sound, the first feedback signal including a signal transmitted from a sound generation unit to a first position through vibration transmission path and air conduction transmission path; outputting a second feedback signal after receiving the second sound, the second feedback signal including a signal transmitted from the sound generation unit to a second position through air conduction transmission path; determining the vibration transfer function from the sound generation unit to the first position based on the first test audio signal, the second test audio signal, the first feedback signal, and the second feedback signal.
