Description

Technical Field

[0001] This utility model relates to a walkie-talkie, specifically an outdoor ski walkie-talkie. Background Technology

[0002] With the increasing enthusiasm and participation in outdoor sports, especially skiing, the market demand for ski walkie-talkies, as an important communication tool to enhance the skiing experience and ensure skiing safety, has risen significantly. Ski walkie-talkies not only need to operate stably in complex, cold environments, but also need to meet the communication needs of skiers during high-intensity activities. However, existing outdoor ski walkie-talkies still have many shortcomings in practical use, specifically in the following aspects:

[0003] Existing ski walkie-talkies typically use simple lanyards or basic securing devices. This design can easily cause the walkie-talkie to shake or even fall off during vigorous activity or on complex terrain. This not only affects the stability of communication but may also lead to equipment damage and increase safety risks for skiers.

[0004] Skiing environments are typically accompanied by strong winds, snow-reflected noise, and the friction noise of ski equipment. These environmental factors can easily interfere with the sound quality of walkie-talkies. Existing walkie-talkies lack effective noise reduction measures, resulting in unclear sound during communication, affecting the user experience and communication efficiency.

[0005] During skiing, equipment is often exposed to snow and strong winds. If the walkie-talkie's waterproof and windproof performance is insufficient, water or snow can easily get into the internal components, affecting the normal operation of the equipment and even shortening its lifespan.
