Document Type and Number:
WIPO Patent Application WO/2023/245661
Kind Code:
A1
Abstract:
Embodiments of the present description disclose earphones, which comprise a first sound wave generation structure, a second sound wave generation structure, an acoustic transmission structure and a filter structure. The first sound wave generation structure and the second sound wave generation structure can generate a first sound wave and a second sound wave respectively, the first sound wave and the second sound wave having a phase difference in the range of 120 to 240 degrees. The acoustic transmission structure can be used for transmitting the first sound wave and the second sound wave to a space point outside the earphones, wherein the first sound wave and the second sound wave transmitted to the space point can interfere in a first frequency range, and the interference reduces the amplitude of the first sound wave in the first frequency range. The filter structure can be used for reducing the amplitude of sound waves in a second frequency range at the space point.
