Problems solved by technology

However, this will not work or be inconvenient if the user adjusts the fit of his earphones during song playback
[0006] Furthermore, state-of-the-art real-time calibration solutions use predicted outputs of loudspeakers, which can be inaccurate and complex
In this solution, a frequency-domain adaptation algorithm is used, which adds complexity to the design of the headset

Abstract

The invention discloses an earphone and a method for performing adaptive adjustment on the earphone. The earphone comprises a preprocessing filter for preprocessing a first audio signal to output a second audio signal; a loudspeaker for playing the second audio signal as a sound wave that enters the ears of a user; a microphone for converting the sound wave into a third audio signal; and an adaptive algorithm unit for performing an adaptive algorithm on a first signal component and a second signal component to update filtering coefficients for the preprocessing filter, wherein the first signalcomponent comprises at least a part of the third audio signal, and the second signal component comprises at least a part of the second audio signal corresponding to the at least a part of the third audio signal.

Description

technical field [0001] The present invention relates to the technical field of earphones, and more particularly, to an earphone and a method for performing adaptive adjustment on the earphone. Background technique [0002] In summary, when a user hears a song through headphones, the bass volume perceived by the user depends on how well the headphones mechanically seal the user's ears. The tighter the earphones seal the ear canal, the greater the bass volume that will be perceived. If there is leakage between the ear canal and the earphones, the perceived bass will be reduced. Handling this perceived difference presents a challenge for headphone developers, since it is impossible to provide consistent bass response to all users with one mechanical design. [0003] A similar situation can apply to any other frequency range which may also vary from person to person. [0004] Earphones may include headphones, earphones such as earbuds, and the like. [0005] In the prior art...
