Abstract
The present disclosure discloses an audio playback method, an audio playback device, a computer-readable storage medium. The audio playback method includes: obtaining a noise signal; obtaining a noise canceling signal by performing a noise reduction process on the noise signal; and playing a low-frequency portion of the noise canceling signal through a first speaker.
Claims16
An audio playback method, comprising:
- obtaining a noise signal;
- obtaining a noise canceling signal by performing a noise reduction process on the noise signal;
- and
- playing a low-frequency portion of the noise canceling signal through a first speaker;
- wherein the playing a low-frequency portion of the noise canceling signal through a first speaker comprises:
- obtaining the low-frequency portion of the noise canceling signal by filtering the noise canceling signal, and playing the low-frequency portion of the noise canceling signal through the first speaker;
- or
- playing the low-frequency portion of the noise canceling signal through device characteristics of the first speaker, wherein the device characteristics of the first speaker are configured to cause the first speaker to meet a preset low-frequency output condition;
- wherein the device characteristics of the first speaker comprise acoustic resistance characteristics of a horn acoustic aperture tuning network and/or damping characteristics of a diaphragm material of the first speaker.
6 more elements
An audio playback device, comprising a first speaker, a processor, and a memory;
- wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to perform:
- obtaining a noise signal;
- obtaining a noise canceling signal by performing a noise reduction process on the noise signal;
- and
- playing a low-frequency portion of the noise canceling signal through a first speaker;
- wherein the playing a low-frequency portion of the noise canceling signal through a first speaker comprises:
- obtaining the low-frequency portion of the noise canceling signal by filtering the noise canceling signal, and playing the low-frequency portion of the noise canceling signal through the first speaker;
- or
- playing the low-frequency portion of the noise canceling signal through device characteristics of the first speaker, wherein the device characteristics of the first speaker are configured to cause the first speaker to meet a preset low-frequency output condition;
- wherein the device characteristics of the first speaker comprise acoustic resistance characteristics of a horn acoustic aperture tuning network and/or damping characteristics of a diaphragm material of the first speaker.
7 more elements
A non-transitory computer-readable storage medium, storing an instruction;
- wherein the instruction is executable by a processor to perform:
- obtaining a noise signal;
- obtaining a noise canceling signal by performing a noise reduction process on the noise signal;
- and
- playing a low-frequency portion of the noise canceling signal through a first speaker;
- wherein the playing a low-frequency portion of the noise canceling signal through a first speaker comprises:
- obtaining the low-frequency portion of the noise canceling signal by filtering the noise canceling signal, and playing the low-frequency portion of the noise canceling signal through the first speaker;
- or
- playing the low-frequency portion of the noise canceling signal through device characteristics of the first speaker, wherein the device characteristics of the first speaker are configured to cause the first speaker to meet a preset low-frequency output condition;
- wherein the device characteristics of the first speaker comprise acoustic resistance characteristics of a horn acoustic aperture tuning network and/or damping characteristics of a diaphragm material of the first speaker.
