Voice-controlled vibration electric bed

Abstract

A voice-controlled vibration electric bed includes a bed base formed of a base support frame and movable frames, a power supply unit mounted at the bed base, a driver electrically connected to the power supply unit for driving the movable frames to move relative to the base support frame, a microcomputer-based control device electrically connected to the power supply unit and the driver, microphones installed in the bed base and electrically connected to the microcomputer, and a vibration device installed in the bed base and electrically connected to the power supply unit and also electrically connected to the control device either directly or indirectly such that the microcomputer matches the sound picked up by the microphones with a predetermined frequency range and controls the vibration device to vibrate subject to the matching result.

         5 . The voice-controlled vibration electric bed as claimed in  claim 4 , wherein the vibration generated by said vibration device subject to the control of said microcomputer is synchronous to the sound that is judged in compliance with said vibration condition. 
     
     
         6 . The voice-controlled vibration electric bed as claimed in  claim 4 , wherein determining the sound to be in compliance with said vibration condition is subject to that the frequency of the sound is smaller than said at least one threshold value. 
     
     
         7 . The voice-controlled vibration electric bed as claimed in  claim 4 , wherein determining the sound to be in compliance with said vibration condition is subject to that the frequency of the sound is greater than said at least one threshold value. 
     
     
         8 . The voice-controlled vibration electric bed as claimed in  claim 4 , wherein determining the sound to be in compliance with said vibration condition is subject to that the frequency of the sound is equal to said at least one threshold value. 
     
     
         9 . The voice-controlled vibration electric bed as claimed in  claim 4 , wherein said at least one threshold value comprises a first threshold value and a second threshold value, said first threshold value being smaller than said second threshold value; determining the sound to be in compliance with said vibration condition is subject to that the frequency of the sound is smaller than said first threshold value or greater than said second threshold value. 
     
     
         10 . The voice-controlled vibration electric bed as claimed in  claim 1 , wherein the amplitude of the vibration generated by said vibration device subject to the control of said microcomputer corresponds to the volume of the sound picked up by said at least one microphone.
