Description

Technical Field

[0001] This utility model relates to the field of audio plug technology, and in particular to a structure that uses a MINI XLR plug to convert an audio plug. Background Technology

[0002] Audio plugs are small interface components used to connect audio devices to audio signal sources or audio output devices. They are usually located at the end of audio devices (such as headphones, speakers, audio receivers, mixers, audio interfaces, etc.) and are used to transmit audio signals. Audio plugs come in a variety of types and designs to meet different application needs. The audio plugs used in headphone devices include six common specifications: 2.5mm, 3.5mm, 4.4mm, 6.35mm, XLR, and MINI XLR. These six connectors each have male plugs and female sockets. Due to the significant differences in size specifications, audio playback devices and headphones will choose one or more specifications depending on the usage environment. When the socket of the audio player and the plug of the headphone are not of the same specification, they are not interchangeable, which requires the use of an adapter. Existing adapters are large and not convenient. Therefore, this utility model proposes a structure that uses a MINI XLR plug to convert audio plugs to solve the problems existing in the prior art.
