Title:

METHOD AND SYSTEM FOR OBTAINING VIBRATION TRANSFER FUNCTION

Document Type and Number:

WIPO Patent Application WO/2022/041167

Kind Code:

A1

Abstract:

Disclosed in the embodiments of the present application are a method and system for obtaining a vibration transfer function. The method comprises: a test signal generation unit generates a first test sound signal and a second test sound signal; a sound generation unit separately generates a first sound and a second sound according to the first test sound signal and the second test sound signal; at least one detector separately receives the first sound at a first position and then outputs a first feedback signal, and receives the second sound at a second position and then outputs a second feedback signal, the first feedback signal comprising a signal that is transferred by the sound generation unit to the first position by means of a vibration transfer path and an air conduction transfer path, and the second feedback signal comprising a signal that is transferred by the sound generation unit to the second position by means of the air conduction transfer path; and a feedback path calculation unit determines the vibration transfer function from the sound generation unit to the first position according to the first test sound signal, the second test sound signal, the first feedback signal, and the second feedback signal.
