Embodiment 1

[0038] like figure 1 As shown, this embodiment discloses a volume adjustment system based on GPS-based smart speaker grouping, including:

[0039]The GPS module placed on each sound box in the group is used to obtain the GPS information of each sound box in the group. In this embodiment, a mobile terminal with GPS information acquisition function placed on each sound box in the group can be used as each sound box in the group. The GPS module on the phone; when the speaker is turned on, the device information of the speaker is obtained through the network. The mobile terminal placed on each speaker in the group obtains the GPS information of the speaker through the supporting client software, and associates the GPS information with the corresponding group speaker.

[0040] The GPS module placed in the active area is used to obtain the GPS information of the active area. In this embodiment, a mobile terminal with GPS function placed in the active area can be used as the GPS mod...

Abstract

The invention discloses an intelligent loudspeaker box grouped volume regulation system and method based on a GPS. The system comprises GPS modules arranged on all loudspeaker boxes in groups, a GPS module arranged in a movement area, a control unit and volume regulation units arranged on all the loudspeaker boxes in the groups. The position information, relative to the movement area, of all the loudspeaker boxes is obtained through all the loudspeaker boxes in the groups and GPS information of the movement area, the main loudspeaker box is selected, the volume of a main loudspeaker box sound source spread to the movement area is calculated according to acoustic attenuation law and the position information of the main loudspeaker box, the volume to be kept and the actual volume of the non-main loudspeaker box are calculated through the acoustic attenuation law and the position information of the non-main loudspeaker box and the position information of the movement area according to the volume, the volume of the non-main loudspeaker box is regulated according to the result, and therefore the volumes of the sounds, spread to the movement area, of all the loudspeaker boxes located at different positions can be kept consistent, the tone quality can be more uniform, and the auditory sense of a user is improved.

Description

technical field [0001] The invention relates to the field of speaker volume adjustment, in particular to a GPS (Global Positioning System, Global Positioning System)-based volume adjustment system and method for intelligent speaker grouping. Background technique [0002] Speakers are a relatively traditional digital product. Even Bluetooth speakers have been developed for a long time, but recently some manufacturers have launched smart speakers that can interact with mobile phones, giving this old product a new look. Interaction with mobile phones may be a relatively elementary level of smart speakers. Relying on technologies such as voice control to realize intelligence without mobile phones is a relatively advanced level of smart speakers, and may also become an important entrance to smart homes. Wang Hanhua said that speakers and TVs will definitely become the center of the family. One reason why smart audio products are promising is that as TVs become thinner and thinne...
