[0027] Please refer to Figure 1 and Figure 2 It is proposed that a sound attenuation device 100, the sound attenuation device 100 includes a shell assembly 1 and a sound insulation device 2, the shell assembly 1 is provided with a sound receiving cavity 13 and a sound attenuation cavity (not shown) communicated with the sound receiving cavity 13, the sound receiving cavity 13 is used for receiving the sound of the user, and the sound attenuation cavity is used for eliminating the sound of the user;The sound insulation device 2 includes sound insulation cotton 21 and a sound insulation pad assembly 22, the sound insulation pad assembly 22 is detachably connected to the shell assembly 1, the sound insulation cotton 21 is detachably connected to the shell assembly 1 and / or the sound insulation pad assembly 22, and covers the cavity wall of the sound receiving cavity 13.

[0028] In the embodiment, the shell assembly 1 collects the user's voice through the sound collecting cavity 13. The user speaks into the sound collecting cavity 13 through the cavity opening of the sound collecting cavity 13. The original voice of the user is collected by the sound collecting cavity 13 and then enters the sound eliminating cavity to vibrate back and forth in the sound eliminating cavity to eliminate the sound, thereby avoiding the leakage of the original voice of the user. In order to further avoid the leakage of the original voice of the user from the sound collecting cavity 13, the shell assembly 1 is provided with a sound insulation device 2. The sound insulation device 2 includes sound insulation cotton 21 and a sound insulation pad assembly 22. The sound insulation pad assembly 22 is connected to the shell assembly 1. When the user speaks into the sound collecting cavity 13 through the cavity opening of the sound collecting cavity 13, the sound insulation pad assembly 22 is arranged around the mouth of the user and tightly abuts the skin around the mouth of the user to avoid the leakage of sound between the mouth of the user and the sound collecting cavity 13. The sound insulation cotton 21 covers the cavity wall of the sound collecting cavity 13 to eliminate the original voice of the user in the sound collecting cavity 13 and improve the sound elimination effect of the original voice of the user in cooperation with the sound eliminating cavity. The sound insulation pad assembly 22 is detachably connected to the shell assembly 1, and the sound insulation cotton 21 is detachably connected to the shell assembly 1 and / or the sound insulation pad assembly 22, so as to facilitate the timely replacement and cleaning of the sound insulation cotton 21 and avoid the breeding of bacteria on the sound insulation cotton 21, thereby affecting the health of the user.

The use of the sound eliminating device 100 includes but is not limited to the following scenarios: the sound eliminating device 100 can be used in combination with a translation device. When the surrounding environment is relatively quiet, the sound of the target language obtained by translation is played through the loudspeaker of the language translation machine. Only the translated target language sound can be heard in the surrounding environment, which is used to create a target language environment to help users learn the target language and improve their listening and speaking ability.

[0031] The sound elimination device 100 can be matched with a communication device. Since the sound elimination device 100 isolates the voice collecting device from the external environment, the voice collecting device cannot collect the noise in the surrounding environment, thereby avoiding the noise in the surrounding environment from interfering with the user's normal speaking voice, without worrying about the interference of the noise in the surrounding environment. Meanwhile, the original voice of the user cannot be heard by the surrounding people, the privacy of the user is ensured, and the surrounding people can also be avoided from being disturbed.
