Audio signal switching structure, identification method and audio signal transmission system

Abstract

The embodiment of the invention discloses an audio signal switching structure, an identification method and an audio signal transmission system. The audio signal switching structure comprises a first plug, a second plug, a connecting line and a connecting plate, the first plug is electrically connected with the first end of the connecting plate through a connecting wire; the second plug is electrically connected with the second end of the connecting plate through a connecting wire; the first plug is connected with audio equipment, and the second plug is connected with external terminal equipment; or the first plug is used for connecting the external terminal equipment and the audio equipment; the first plug comprises a first grounding terminal and a first microphone terminal, and the second plug comprises a second microphone terminal and a second grounding terminal; the arrangement positions of the first grounding terminal and the second grounding terminal are different, and the arrangement positions of the first microphone terminal and the second microphone terminal are different. Two different plugs are simultaneously connected through the continuous line and the connecting plate, the use requirements of different devices are met, audio signal transmission is achieved, and meanwhile the manufacturing cost is effectively saved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of audio switching cables, and in particular, relate to an audio signal switching structure, an identification method, and an audio signal transmission system. Background technique [0002] With the development of science and technology, electronic smart products play an important role in people's lives. With the diversification and popularization of electronic smart products, a variety of cable standards have emerged, among which audio cable is used as a line for transmitting sound signals. Usually, an audio connection cable can only meet one standard and has a single function. Due to the incompatibility between various standards, multiple transfer cables are required to achieve different connection functions, resulting in waste of resources and increased manufacturing costs. The use of smart products is restricted. It has imposed great restrictions and brought inconvenience and troubl...
