[0002] With the development of electronic products, people are using more and more types and quantities of electronic products, such as mobile phones, computers, media players, televisions, and stereos, which have become common in people's daily lives. These electronic products are usually equipped with audio interfaces, which are connected to headphones or other audio devices via audio adapter cables to play music to users.

[0003] Traditional audio adapter cables mainly consist of a metal audio plug and an audio cable. In daily life, audio adapter cables allow for flexible connection and combination of various electronic products. To ensure the stability and reliability of audio signal transmission, the connection between the audio plug and the audio interface is usually quite tight. However, during use, the audio adapter is frequently plugged and unplugged from the audio interface of electronic products. After prolonged use, the audio adapter and audio cable are prone to loosening, poor contact, or damage, resulting in the inability to transmit audio data normally. Furthermore, existing audio adapters lack protective devices, and water can easily cause short circuits and damage to the equipment, greatly reducing the lifespan of the audio adapter cable. Especially when not in use, dust can easily accumulate on the adapter plug, affecting the performance and causing certain adverse effects on users. In addition, existing audio adapter cables have a complex structure, making them inconvenient to process and assemble, greatly reducing production efficiency, increasing costs, and making them inconvenient to carry when traveling.

[0004] Therefore, there is an urgent need for engineers in this field to develop an audio adapter cable that is simple in structure, easy to process and assemble, low in cost, reliable, long in service life, and easy to carry. Utility Model Content
