Title:
METHOD FOR CORRECTING ACOUSTIC PROPERTIES OF A LOUDSPEAKER, AN AUDIO DEVICE AND AN ELECTRONICS DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/143472
Kind Code:
A1
Abstract:
A method for correcting acoustic properties of a loudspeaker, an audio device and an electronics device are disclosed. The method comprises: obtaining a volume velocity of a diaphragm of the loudspeaker; obtaining a sound pressure of the loudspeaker; determining an acoustic impedance and/or an acoustic resistance of the loudspeaker, wherein the acoustic impedance is given by the ratio of the sound pressure to the volume velocity; and correcting the acoustic properties of a loudspeaker by using the acoustic impedance and/or the acoustic resistance.
