Title:
AUDIO IMAGE CONTROL METHOD, HEADPHONES, AND HEADPHONE ATTACHMENT
Document Type and Number:
WIPO Patent Application WO/2020/110745
Kind Code:
A1
Abstract:
This audio image control method controls the localization of an audio image in a space between a headphone/speaker and the auricle. Rearward sound emitted from the headphone/speaker at a position corresponding to the rear of the auricle and traveling toward the auricle is blocked and reflected to travel away toward the front of the auricle. The reflected rearward sound is reflected together with forward scattering sound emitted from the headphone/speaker at a position forwardly of the auricle and travelling away from the auricle, and is allowed to reach the auricle as reflected forward sound travelling from the front of the auricle toward the auricle. Central sound emitted from the central portion of the headphone/speaker and travelling toward the auricle, and emitted forward sound emitted from the headphone/speaker at a position corresponding to the front of the auricle and traveling toward the auricle are allowed to reach the auricle directly.
