This utility model discloses a speaker sound outlet cavity structure, including a sound outlet cavity, a speaker, and a pad. The speaker is installed at the upper end of the sound outlet cavity, and the pad is installed at the lower end of the sound outlet cavity. The upper side of the pad has several spaced-apart recesses. One side of the sound outlet cavity has a sound outlet. The speaker and the pad are vertically opposite each other, with the speaker's sound output direction facing the upper side of the pad. The sound emitted by the speaker is reflected by the upper side of the pad and the recesses of the pad before being output from the sound outlet. This utility model can further improve sound loudness and bass effect, and can make the emitted sound have a stereo surround sound effect.

The present invention discloses audio glasses and an audio signal processing method and storage medium thereof, the method comprising: obtaining an audio signal to be output, and determining the signal amplitude of the audio signal to be output; when the signal amplitude is greater than or equal to a preset amplitude, obtaining a pre-created filtering model and an expected frequency band; performing frequency division processing on the audio signal to be output according to the expected frequency band and the filtering model to obtain a target audio signal containing only the expected frequency band; and outputting audio based on the target audio signal. The present invention solves the technical problem that current audio glasses cannot provide an audio experience that meets user needs when both large and small audio signals are present, and achieves sound quality assurance when the audio signal amplitude is small, and can improve the sound loudness when the audio signal amplitude is large, and also ensures the sound quality, which is conducive to meeting the listening needs of customers.
