The invention relates to the technical field of audio equipment, in particular to a television audio infrared transmitting and receiving device. The device comprises an infrared transmitting box and areceiving earphone, wherein the infrared transmitting box comprises an transmitting box body; the upper surface of the transmitting box body is provided with at least one placing groove which is matched with the receiving earphone and can be used for placing the receiving earphone; a limiting mechanism for limiting the movement of the receiving earphone is arranged between the placing groove andthe receiving earphone. The upper surface of the infrared transmitting box is provided with the placing groove which is matched with the receiving earphone and can be used for placing the receiving earphone so that the space occupied by the receiving earphone is saved, the receiving earphone has a specific placement position and is convenient to use next time, and meanwhile, the limiting mechanismfor limiting the movement of the receiving earphone is arranged between the placing groove and the receiving earphone, so that the phenomenon of rollover when the receiving earphone is placed can beeffectively prevented.
Description
【Technical field】 [0001] The invention relates to the technical field of audio equipment, in particular to a TV audio infrared transmitting and receiving device. 【Background technique】 [0002] When people watch TV and listen to the sound, they often cannot listen to the TV sound normally due to external noise interference, or because the sound is too loud to affect other people's work or rest when watching TV. It can solve this type of problem, but it is inconvenient to use with a cable, and it will trip others. Therefore, a TV infrared audio signal transmitter and receiver has appeared. Through the infrared wireless transmitter, receiver and stereo earphone device, it can High-quality TV stereo sound is received wirelessly, but this kind of TV infrared audio signal is transmitted to the receiver, and the receiving earphone is connected to the transmitter without cables. This kind of receiving earphone generally does not have a specific placement position, and is placed ran...
