发明名称 DEVICE AND METHOD FOR IN-EAR SOUND GENERATION
摘要 A device for in-ear sound generation comprises a sound determining unit adapted to determine a first sound signal, a sound collecting unit exposed to the ear canal and adapted to collect a second sound signal, a sound correction determining unit adapted to determine a third sound signal, and a loudspeaker exposed to an ear canal and adapted to emit the third sound signal The third sound signal includes the first sound signal and a correction component, the correction component essentially corresponding to a weighted and phase-inverted signal. The phase-inverted signal is obtained by phase inversion from a difference signal essentially corresponding to a difference between the second sound signal and the first sound signal.
