  General mobile phones and other smartphones are provided with speakers for outputting voice and music, but microspeakers are used due to space constraints. As new technologies are born one after another, high-quality sound sources are installed in the mobile phone itself, but the music played from mobile phone speakers does not reach the sound quality of conventional speakers and the volume is also limited. The

  In the market, speakers or audio boxes connected to mobile phones are born one after another with different transmission methods (eg, audio cable 3.5 mm, USB or Bluetooth (registered trademark)), and music from mobile phones is transmitted by external speakers. It can be played as music with good sound quality. However, the sound quality of the music reproduced and played in such a way is not as good as the original quality of mobile phones. This is because the sound quality inherent to the mobile phone is impaired because it is reproduced after being processed by the loudspeaker of the external speaker itself.

Is provided. And when a mobile phone is inserted into the insertion port in the audio box, there are quite large gaps in the front, rear, left and right of the mobile phone, so the sound from the mobile phone leaks out of the insertion port as it is, and the sound source is audio It cannot be completely reflected and vibrated in the box, and the sound quality from the audio box cannot be expected.

  As described above, in order to improve the problem that the voice cannot be completely reflected and vibrated in the audio box because a part of the voice of the mobile phone amplified by the conventional audio box leaks from the insertion port of the mobile phone. In the present invention, the open side is provided with a voice transmission tube provided so that a closed adjustment pipe on the outer end side is fitted, and an insertion port corresponding to the opposite side of the pipe surface of the voice transmission pipe and the adjustment pipe is provided. When the adjustment tube expands and contracts or rotates, the opening formed between the two insertion ports is provided so as to correspond to the width and thickness of the mobile phone inserted therein, and the opening and the mobile phone Can be adhered to each other. This prevents sound leakage and completely reflects and vibrates the cellular phone tone so that a loud sound from the trumpet-shaped opening can be reproduced with high sound quality. Providing a voice tube with.

  As a technical means for solving the problems of the present invention, a one side is closed, a trumpet-shaped opening is provided, and a tube is provided with an insertion port on the tube surface. And an adjustment tube that is closely inserted into and fitted into the transmission tube, and an insertion port corresponding to the insertion port of the transmission tube is provided on the tube surface of the adjustment tube.
