Summary:Disclosed is an anti-interference highly sensitive audio vibration prompting device for deaf-mutes, which resolves the problems that deaf-mutes, old people and people who are hearing impaired cannot sense various sounds. The audio vibration prompting device comprises an MIC, an operational amplifier circuit, a trigger circuit and a micro-vibration motor, wherein audio signals collected by the MIC are inputted to the micro-vibration motor after being processed by the operational amplifier circuit. By utilizing the design of double operational amplifier circuit, the audio vibration prompting device is enabled to work in both static environment and dynamic environment without being affected by using environment. Simultaneously, frequency response can be adjusted in the range of 50-1000 Hz. Besides, the frequency response has a wide receiving range in both static environment and dynamic environment and the receiving sensitivity can be adjusted to vibrate in time to warn users according to the real needs of the us
