Embodiment 1

[0021] figure 1 It is a flow chart of an audio playing method provided by Embodiment 1 of the present invention. The method of this embodiment can be executed by an audio playback device, the device can be implemented by means of software and / or hardware, and can generally be integrated into a smart terminal. Such as figure 1 As shown, the audio playback method provided in this embodiment specifically includes:

[0022] S110. Establish a communication connection with a set speaker, where at least one sub-speaker is arranged on the set speaker.

[0023] Stereo sound refers to sound with a stereo effect. To produce stereo sound, at least two speakers are required. The two speakers here refer to speakers that exist in different positions, and the distance between the two positions should be large enough The degree to which the left and right ears perceive. When different sounds are played from different spatial positions, people feel as if they are personally on the scene and...

Embodiment 2

[0036] figure 2 It is a flow chart of an audio playing method provided by Embodiment 2 of the present invention. This embodiment optimizes Embodiment 1. Specifically, in this embodiment, the audio playback method includes:

[0037] S210. Establish a communication connection with a set speaker, where at least one sub-speaker is provided on the set speaker.

[0038] S220. Determine position information of all speakers according to the smart terminal microphone array.

[0039] There is a microphone array in the smart terminal, and the microphone array may have at least three microphones, and the three microphones can obtain the accurate spatial position of the speaker from a three-dimensional perspective. Accurate positions of all speakers can be obtained through the microphone array, that is, the direction, distance and relative height of the speakers relative to the smart terminal.

[0040] For multi-channel audio files such as stereo and 5.1 channels, there are certain sta...

Embodiment 3

[0049] image 3 It is a structural diagram of an audio playback device provided in Embodiment 3 of the present invention, and the device can be configured in a smart terminal. Such as image 3 As shown, the device may include: a speaker connection module 31 , a parameter determination module 32 and an audio playback module 33 .

[0050] Wherein, the speaker connection module 31 is used to establish a communication connection with the set speaker, and the set speaker is provided with at least one sub-speaker;

[0051] The parameter determination module 32 is used to determine the playback parameters of all speakers according to the frequency response parameters of the at least one secondary speaker and the frequency response parameters of the main speaker set on the smart terminal, the playback parameters including playback time and playback volume;

[0052] The audio playing module 33 is configured to control all speakers to play the audio file according to the playing param...

Abstract

The invention discloses an audio playing method and device. The method comprises the steps of establishing communication connection with a set loudspeaker box, wherein the set loudspeaker box is equipped with at least one secondary loudspeaker; determining playing parameters of all loudspeakers according to the frequency response parameter of the at least one secondary loudspeaker and the frequency response parameter of a master loudspeaker arranged on a smart terminal, wherein the playing parameters comprise playing time and playing volume; and controlling all loudspeakers to play an audio file according to the playing parameters. According to the technical scheme provided by the embodiment of the invention, the problem that in the prior art, the smart terminal cannot play the audio file according to a three-dimensional effect through an internal loudspeaker or a single external loudspeaker is solved.

Description

technical field [0001] The present invention relates to the technical field of audio processing, in particular to an audio playing method and device. Background technique [0002] Modern smart devices all have audio recording and playback modules such as microphones and speakers, which facilitate people to play audio files such as music and radio, and enrich people's entertainment life. [0003] At present, many smart devices such as mobile phones and watches have only one speaker due to volume limitations, and cannot achieve stereo effects when playing audio externally. They only play mono-channel audio. The sound effect is often not very good, and the user experience is poor. Even if the smart device contains two speakers, because the positions of the two speakers are not much different, it is also unable to produce a significant stereo effect. And when the smart device plays audio through an external speaker, if the smart device is only connected to one speaker, it will ...
