Embodiment Construction

[0053] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054] The present invention provides a volume adjustment method for coordinated playback, such as figure 1 As shown, it shows a schematic flowchart of the portable terminal side in the first embodiment of the volume adjustment method for coordinated playback in the present invention. The volume adjustment method for coordinated playback includes:

[0055] S10. After establishing a connection with the cooperative terminal, the portable terminal allocates the frequency of the high-frequency detection segment to each loudspeaker on the cooperative terminal, and correspondingly sends the allocation result to the cooperative terminal where each loudspeaker is located;

[0056] The portable terminal can be wearable devices such as smart glasses, smart watches, smart bracelets, and smart clothing, or other portable terminal...

Abstract

A cooperative playback volume adjustment method, comprising: after a portable terminal establishes a connection with a cooperative terminal, allocating a frequency of a high frequency detection fragment for each speaker within a plurality of speakers on the cooperative terminal, and correspondingly sending an allocation result to the cooperative terminal where each speaker is located; collecting audio data during cooperative playback, and calculating the current sound pressure of the high frequency detection fragment of each speaker according to the collected audio data and the frequency of the high frequency detection fragment of each speaker; adjusting the volume of each speaker according to a preset sound pressure of each speaker and the current sound pressure of the high frequency detection fragment.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a volume adjustment method and device for coordinated playback, and a coordinated playback device. Background technique [0002] In the audio playback scenario, a single terminal cannot provide users with stereo playback sound effects due to the limitation of the number of speakers in its audio equipment. Even if some terminals are equipped with dual speakers, the distance between the two speakers is very limited. Can not form a good stereo playback effect. Using multiple terminals to play different channels of the same audio cooperatively can form a stereo playback effect. However, when multiple speakers of a cooperative terminal composed of one or more terminals are used to cooperatively play the same audio If the speaker is in the middle of the speaker, the volume received by the user will become uneven. Even when the user is too close to some speakers, t...
