Rotary sound box

Abstract

The invention discloses a rotary sound box. The rotary sound box comprises a base, a main shaft, a plurality of loudspeakers and a Bluetooth control module, wherein the main shaft is erected on the base; the loudspeakers are arranged on the main shaft; the height directions of the plurality of loudspeakers along the main shaft are different; the loudspeakers can rotate relative to the center line of the base to change the facing directions of the loudspeakers; and the Bluetooth control module transmits audio signals to the loudspeakers at different frequencies in a non-interfering way. Compared with the prior art, the rotary sound box has the advantages that the plurality of loudspeakers are distributed at different heights of the main shaft, and face different directions, so that the structure is relatively simple. During use, the factors of turn-on / off, volumes and the like of the loudspeakers are controlled independently through the Bluetooth control module, so that a relatively good sound quality effect is achieved, and the rotary sound box is suitable for various places. Bluetooth control is non-directional; the problem in control of signal directivity is solved; and operations are relatively convenient.

Description

technical field [0001] The invention relates to the technical field of audio, in particular to a rotary audio. Background technique [0002] In the prior art, sound systems are widely used in various places, adding diversified sound elements to people's lives, and are indispensable sound equipment in modern society. With the development of wireless communication technology, the performance of audio system has also been greatly improved. A wireless audio system that uses a controller to control playback has appeared on the market. This wireless audio system includes a speaker and a controller. The controller has an infrared transmitting module built in, and the audio has a corresponding infrared receiving module for receiving signals. , the audio data transmitted by the audio controller is played wirelessly. However, the existing audio system still cannot be placed arbitrarily relative to the position of the audio source player, and there may be situations where signals can...

AI Technical Summary

Problems solved by technology

However, the existing speakers still cannot be placed arbitrarily relative to the position of the audio player, and there may be situations where the signal cannot be received normally

The reason is that the emission tube corresponding to the infrared transmission module of the sound source playback controller has a direction when transmitting the signal. If the speaker is placed too far away from the emission direction of the emission tube, it will affect the reception of the signal and make it impossible to play normally. , the structure is complicated, the operation is inconvenient, and it also affects the playback sound effect

In addition, the existing speakers can only emit sound in one direction, and the scope of applicable occasions is relatively small. With the continuous improvement of people's high requirements for the quality of life, the existing speakers cannot meet the needs
