Technical Field
[0001] The utility model relates to the technical field of TWS wireless earphones, in particular to a head-mounted noise reduction earphone with easy replacement of earmuffs. Background Art
[0002] Headphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears. Headphones can be separated from the media player and connected using only one plug, so you can listen to the audio without disturbing others. They can also isolate the sounds of the surrounding environment, which is very helpful for people who use them in noisy environments such as recording studios, bars, travel, and sports.
[0003] Among them, head-mounted noise-cancelling headphones are a special type of headphones, the main purpose of which is to reduce or eliminate external noise so that users can listen to music or sounds better. The working principle of this type of headphones is mainly based on reverse noise cancellation technology. Head-mounted noise-cancelling headphones have a built-in micro-microphone to collect noise from the user's surrounding environment and convert it into a digital signal. This digital signal is then processed and produces a sound wave opposite to the noise to eliminate the noise. Finally, the noise-cancelled audio is transmitted to the user's ears through the earplugs, allowing the user to hear clear music or sounds.
[0004] The earmuffs of common head-mounted noise-cancelling headphones are usually made of leather outer covers, which are prone to dirt or damage after being used for a period of time, affecting the user experience and need to be replaced. However, common earmuffs are usually installed on the headphones by bonding, and the residual glue needs to be cleaned during replacement, which makes replacement more troublesome.

[0029] Example 1: Please refer to Figure 1-4 A head-mounted noise-cancelling headset with easy-to-replace earmuffs comprises two symmetrical earphone shells 1, a fixed connection cover 2 is fixedly installed on the opposite side of the two earphone shells 1, a movable connection cover 3 is threadedly installed on the surface of the fixed connection cover 2, and an anti-drop component 4 is arranged on the upward surface of the earphone shell 1.
[0030] Among them, a frame 5 is fixedly installed on the surface of the movable connection cover 3, a soft bag 6 is fixedly installed on the surface of the frame 5, a sound transmission hole 7 is opened on one side of the fixed connection cover 2 and the movable connection cover 3, and a soft pad 8 is fixedly installed on one side of the movable connection cover 3. The movable connection cover 3, the frame 5 and the soft bag 6 on its surface constitute the earmuff of the earphone.
[0031] At the same time, the anti-drop component 4 includes a pressing rod 41 that passes through the upward surface of the earphone housing 1, and a connecting plate 42 is fixedly installed at the bottom end of the pressing rod 41 located inside the earphone housing 1, and a limiting column 43 is fixedly installed at the top of the connecting plate 42 located inside the fixed connecting cover 2.
[0032] Among them, a mounting through hole 101 is opened on the upward surface of the earphone housing 1, and the pressing rod 41 is inserted into the mounting through hole 101. A sliding groove 102 is opened on one side of the earphone housing 1, and the connecting plate 42 is slidably installed inside the sliding groove 102.
[0033] Secondly, a through hole 201 is formed on the upward surface of the fixed connection cover 2 , and a limiting groove 301 is formed on the upward inner surface of the movable connection cover 3 .
