Description
Technical Field
[0001] The utility model relates to the field of wireless earphones, in particular to a waterproof structure of wireless earphones. 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. There is little difference in sound quality between wireless headphones and wired headphones, but wireless headphones are more convenient to use. The main difference is that the wire in the middle is replaced by radio waves.
[0003] When wireless headphones are not in use, people tend to hang them around their necks. In rainy or snowy weather, if the headphones are hung around their necks, rainwater will enter the headphones through the sound holes and affect the internal components of the headphones. This may easily cause a short circuit in the internal components of the headphones, which is not conducive to long-term use of the headphones. Utility Model Content

[0030] Reference Figure 1-5The utility model provides a waterproof structure of a wireless headset: it includes a shell 1, a partition 4 is installed on the inner side of the shell 1, and a sound hole 5 is opened on the surface of the partition 4 to facilitate the sound generated by the speaker 2 to enter the user's ear, a first connecting hole 6 is opened on the side of the partition 4, and a second connecting hole 7 is opened on the side of the shell 1. The position of the first connecting hole 6 corresponds to the position of the second connecting hole 7, which is convenient for the installation of a waterproof plate 8, a waterproof plate 8 is installed inside the shell 1, and a through hole 9 is opened on the surface of the waterproof plate 8. The position of the through hole 9 corresponds to the position of the sound hole 5. When the through hole 9 is aligned with the position of the sound hole 5, the sound can pass through the through hole 9 and the sound hole 5 into the user's ear, and a waterproof rubber 10 is fixedly connected to the outer surface of the waterproof plate 8. The waterproof rubber 10 is located between the partition 4 and the waterproof plate 8. The waterproof rubber 10 has elasticity, and can reduce the distance between the waterproof plate 8 and the partition 4. Vibration, improve the sound quality of the earphone when in use, when the waterproof rubber 10 is aligned with the position of the sound outlet 5, it can prevent external rainwater from entering the interior of the earphone and causing damage to the internal components of the earphone, and the side of the waterproof plate 8 is fixedly connected with a fixing rod 11, and the end of the fixing rod 11 away from the waterproof plate 8 passes through the second connecting hole 7 and the first connecting hole 6 to the outside of the partition 4 in sequence, and the fixing rod 11 can move up and down inside the first connecting hole 6 and the second connecting hole 7, and the position of the waterproof plate 8 can be adjusted by pushing the fixing rod 11, so as to obtain different effects, when the position of the sound outlet 5 corresponds to the position of the through hole 9, the sound generated by the speaker 2 can be directly transmitted to the outside of the earphone and received by the user, and when the position of the sound outlet 5 corresponds to the position of the waterproof rubber 10, the waterproof rubber 10 will block the sound outlet 5, and at this time, external rainwater will not enter the interior of the earphone along the sound outlet hole, and affect the speaker and other equipment inside the earphone.
[0031] There are multiple sound holes 5 and multiple through holes 9, which facilitate the propagation of the sound generated by the speaker 2. There are multiple waterproof rubbers 10, which are respectively located between the multiple through holes 9. The position of the waterproof plate 8 can be adjusted to block the sound hole 5 with the waterproof rubber 10, thereby enhancing the waterproofness of the earphone.
[0032] A speaker 2 is fixedly connected to the inner wall of the shell 1, and sound is generated through the speaker 2 to facilitate the use of the earphone.
