example 1

[0099] Example 1, if the slave speaker sends the second angle l to the main speaker. see Figure 7A As shown, after the main speaker receives the second angle l sent from the speaker, the second ray can be determined according to the second angle l in the x1-y1-z1 coordinate system, for example Figure 7A The second ray shown in . The main speaker can also be based on the first angle The first ray is determined in the x1-y1-z1 coordinate system. The main speaker determines that the intersection point Q between the first ray and the second ray is the user's position.

example 2

[0100] Example 2, if the slave speaker sends the functional relationship of the second ray formed by the second angle l in the second coordinate system, that is, the x2-y2-z2 coordinate system, to the master speaker. Then the main speaker receives the functional relationship of the second ray (for example, y=ax+b), and the functional relationship is determined in the coordinate system constructed from the speaker, which is not the same coordinate as the coordinate system constructed by the main speaker Tie. Therefore, the main speaker can coordinately transform the functional relationship of the second ray into the functional relationship of the third ray in the x1-y1-z1 coordinate system constructed by the main speaker. In this way, the main speaker can determine that the intersection point between the first ray and the third ray is the user's position. Exemplary, see Figure 7B As shown in , after the main speaker receives the functional relationship of the second ray corr...

Abstract

The invention discloses a sound box control method, a sound box and a sound box system, and relates to the fields of intelligent terminals, man-machine interaction and the like. The method comprises the steps that a first sound box collects a first sound signal, and a second sound box collects a second sound signal; the first sound box determines the position of a sound source according to the first sound signal and the second sound signal, and determines a first distance between the sound source and the first sound box and a second distance between the sound source and the second sound box; the first sound box determines a time delay difference based on the first distance and the second distance; the first sound box indicates the second sound box to make a sound at a second moment, the second moment is determined according to the first moment and the time delay difference, and the first moment is the sound making time of the first sound box; the first sound box sends out a third soundsignal at a first moment, and the second sound box sends out a fourth sound signal at a second moment, the third sound signal and the fourth sound signal are signals of different sound channels of the same audio file. In this way, a user can obtain a good three-dimensional sound effect at different positions in a room.

Description

technical field [0001] The present application relates to the technical field of terminals, and in particular to a speaker control method, a speaker and a speaker system. Background technique [0002] At present, more and more households install speakers to enhance the effect of audio playback. Usually, the main activity area of ​​people in the room (may be referred to as the active area) is relatively fixed. For example, if a person spends a long time on the sofa (resting / watching TV / listening to music / reading, etc.), the area where the sofa is located is the active area. When the speaker is placed in a fixed position in the room, the corresponding position where better sound effects can be heard is also determined. Taking two speakers as an example, assuming that speakers 1 and 2 are installed on both sides of the TV cabinet, there is only a fixed area opposite the TV cabinet (the fixed area is equilateral with the area 1 where the speaker 1 is located and the area 2 whe...
