A kind of directional playback adjustment device for intelligent audio

Abstract

The invention relates to a directional playing regulation device for an intelligent loudspeaker. The directional playing regulation device comprises a base, a bearing cavity, a rotary table mechanism,an annular guide rail, a distance measuring device, a human body sensor, a decibel detecting device and a control circuit. The annular guide rail and the rotary table mechanism are arranged on the upper surface of the base, and the base is mutually connected with the bearing cavity through the annular guide rail and the rotary table mechanism. The distance measuring device, the human body sensorand the decibel detecting device are embedded to the outer surface of the bearing cavity and axially perpendicular to the bearing cavity. The bearing cavity comprises a positioning groove, adjusting plates, adjustment driving mechanisms, a reflective plate, slide grooves and positioning fasteners. The directional playing regulation device is simple in structure, flexible and convenient to use, high in universality and high in detecting and positioning precision, accurate positioning of audience distribution positions and the distance between audiences and the loudspeaker can be realized effectively, directional regulation of sound waves sent by the loudspeaker is realized, and accordingly loudspeaker equipment utilization efficiency is remarkably improved while noise pollution is abated.

Description

technical field [0001] The invention relates to a human body positioning device, in particular to a directional playback adjustment device for an intelligent audio system. Background technique [0002] At present, when performing large-scale information playback, audio is one of the most important information playback devices at present, and it is used in a huge amount. However, in actual use, it is found that when the audio equipment is running, there is often a big difference between the distribution position of the audience and the best playback position of the audio, so the audience often cannot get the best playback position when the audio equipment is playing. Listening effect, thus seriously affecting the playback quality, and currently addressing this problem, mainly by increasing the volume of the stereo to achieve the purpose of improving the audience's listening effect, but this method on the one hand caused a large energy consumption, on the other hand It will a...

[0002] At present, when performing large-scale information playback, audio is one of the most important information playback devices at present, and it is used in a huge amount. However, in actual use, it is found that when the audio equipment is running, there is often a big difference between the distribution position of the audience and the best playback position of the audio, so the audience often cannot get the best sound when the audio equipment is playing. Listening effect, thus seriously affecting the playback quality, and currently addressing this problem, mainly by increasing the volume of the stereo to achieve the purpose of improving the listening effect of the audience, but this method on the one hand caused a large energy consumption, on the other hand It will also cause serious noise pollution. Therefore, in response to this problem, it is urgent to develop a device that detects the position of the listener and drives the audio to play directional when the audio is playing, so as to meet the needs of actual use.
