Detailed Description

Referring to fig. 1 to 5, which show specific structures of a plurality of embodiments of the present invention, a headset with a telescopic sound guiding tube 30 includes a headset body 10, a microphone rod 20 and a sound guiding tube 30. The left end of the microphone rod 20 is connected with the earphone body 10, a microphone 202 is arranged in the right end of the microphone rod 20, and a sound pickup hole 201 is formed in the periphery side of the right end of the microphone rod 20;

the sound guide tube 30 is sleeved on the periphery of the microphone rod 20, and the sound guide tube 30 can slide in the left-right direction relative to the microphone rod 20. During the sliding process, the right end of the microphone rod 20 and the sound pickup hole 201 are always located in the sound guide tube 30. Preferably, the length of the sound guide tube 30 is less than the length of the microphone stem 20. When the talking function is not used, the sound guide tube 30 can be retracted, so that the earphone has a small appearance.

In the first embodiment, a left end limiting step part 31 is formed inside the left end of the sound guide tube 30 close to the microphone rod 20, and a first limiting step part 21 is formed on the outer periphery side of the microphone rod 20 in the sound guide tube 30; a right end limit step 32 is formed inside the right end of the sound guide tube 30.

As shown in fig. 1, when the sound guide tube 30 slides rightward relative to the microphone rod 20 (when the sound guide tube 30 is in an extended state), the first limit stepped portion 21 abuts against the left limit stepped portion 31.
