Problems solved by technology

[0002] The working principle of the traditional remote control is to transmit the data signal from the infrared emitting tube through the infrared light, and then receive it through the infrared receiving tube. Since the infrared light is used as the carrier, its transmission path is easily blocked by obstacles.
In addition, due to the limitation of the infrared transmission power of the traditional remote control, the working distance of the remote control is basically within 10 meters; due to the characteristics of the emission tube, the traditional remote control has the defect of the remote control angle, and cannot work normally at 360 degrees.

Abstract

The invention relates to a remote control loudspeaker box comprising a loudspeaker box body and a remote controller for remotely controlling the loudspeaker box body, wherein the remote controller comprises a shell, a first circuit board, a display screen, an operating panel and a battery installed in the shell, and a radio wave transmitting end arranged on the first circuit board and used for transmitting wireless signals; the loudspeaker box body comprises a box and a second circuit board installed in the box, and a radio wave receiving end, corresponding to the radio wave transmitting end,arranged on the box; and the radio wave transmitting end and the radio wave receiving end work under the radio wave environment of 215-300MHz. The remote control loudspeaker box adopts radio waves asa carrier, which does not have directionality in both transmission and receipt. The penetrating power of the radio waves is relatively strong, without being affected by common barriers; and the transmission power can be adjusted according to actual conditions to achieve the purpose of remote control.
