Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0011] As shown in the attached figure, the mobile phone presses the answer button or slides the screen to talk, inserts the 11 connection line, and puts on the 12 vacuum cavity soundproof helmet. 13 The vacuum chamber mask is aimed at the oral cavity, and 14 the speaker is aimed at the ear, and the conversation starts. The 16 defibrillation soft films inside the 15 ventilation tube are vibrated by ambient noise sound energy and airflow while ventilating and adjusting the pressure difference inside and outside the helmet, consuming part of the sound energy. 12 Vacuum chamber helmets, 13 Vacuum chamber mouth mask inner and outer shell connection edges, 17vm type rubber pads at 15 ventilation pipe two ends, block the inner and outer walls of the vacuum chamber periphery, and keep the airtightness of the vacuum chamber. 18 scarves wrap around the...

Abstract

The invention discloses a vacuum-cavity sound insulation helmet, and relates to a communication voice assistance processing device. In a high-noise working environment, the weight of a phone is borne by the helmet, and the hands are liberated. Sound insulation is achieved through a multi-layer vacuum-cavity sound insulation hood, and therefore the clear communication quality is guaranteed.

Description

technical field [0001] The invention relates to a telephone muffler, in particular to an oral communication environment noise shielding device. Background technique [0002] When you are in a high-noise working environment and cannot leave your post, you cannot spare your hands to answer the phone for a long time. Even if the call is made, the other party cannot hear the call clearly. The vacuum cavity soundproof helmet supports the overall weight of the phone, freeing up both hands to continue working. At present, there is no such sound-proof product for calls. The vacuum cavity sound-proof helmet plus the vacuum cavity mask, and the double-layer vacuum cavity can effectively reduce the interference of environmental noise on the content of the call. Contents of the invention [0003] The purpose of the present invention is to use the helmet to support the weight of the phone in a high-noise working environment that cannot leave the post, so as to free hands. The use of...
