Description

Technical Field

[0001] The utility model relates to a throat vibration device. Background Art

[0002] The throat vibration device uses a non-traditional sound pickup method. The voice it receives is converted from the sound signal made by the vibration of the throat vocal system.

[0003] Existing throat vibration devices generally include a shell and a buzzer plate arranged in the shell, wherein the inner side of the shell contacts the skin of the human throat, and the vibration of the user's throat is transmitted to the buzzer plate through the wall of the shell, and then the buzzer plate converts the vibration signal into an electrical signal. However, part of the energy of the human throat vibration will be dispersed by the shell itself, so that the sensitivity of the throat vibration device is affected. In addition, the existing throat vibration device has a poor ability to resist wind noise, and its wind noise resistance performance still needs to be further improved. Utility Model Content
