Embodiment 2

[0027] Embodiment 2: as image 3 As shown, this embodiment is an implementation when there are multiple users. Wherein, the audio device has 3 sound boxes, respectively 21, 22, and 23 from left to right, and an infrared range finder 12 is arranged on the sound box 22, and the rotating mechanism of the sound box base is an electric motor 3, and the automatic The method for adjusting the sound direction and time delay of the sound device to achieve the best sound effect includes the following steps:

[0028] 1) Obtain user location data through the infrared rangefinder, and then input the user location data into the sound output direction control module of the speaker;

[0029] 2) The speaker sound output direction control module determines the user position according to the input data, and determines that the total number of users is 3, then the serial number of the target user is the smallest integer greater than 3 / 2, that is, the second one.

[0030] 3) The sound output dir...

Abstract

The invention relates to the field of home audios, in particular to a method for automatically adjusting the sound direction and time delay of an audible device and achieving the best sound effects. The method includes the steps: recognizing a user position, adjusting directions of loudspeakers and enabling a sound output direction to directly face a target user; measuring the distance between each loudspeaker and a user, adjusting the sound time delay of the loudspeakers and enabling sound of each loudspeaker to simultaneously reach the user. By the steps, the sound direction and the time delay of the loudspeakers are automatically adjusted to achieve the best sound effects.

Description

technical field [0001] The invention relates to the field of home audio, in particular to a method for automatically adjusting the sound direction and time delay of an audio device to achieve the best sound effect. Background technique [0002] Most of the existing home theater speakers are fixedly placed. Users can only hear the best sound effect at a certain point. If the user's position is shifted, it is necessary to manually adjust the sound angle and sound delay to achieve better results. Because it is manually adjusted, it is highly random, and it is difficult to adjust to the best effect. At the same time, it needs the cooperation of many people to complete the adjustment, which is inconvenient to operate. Contents of the invention [0003] The purpose of the present invention is to provide a method for automatically adjusting the sound direction and time delay of an audio device to achieve the best sound effect. [0004] A method for automatically adjusting the so...
