Electric bed or chair movable along with ambient sounds

Abstract

An electric bed or chair includes an actuator connected with a base and a movable frame, a vibrator disposed on the movable frame, a control unit controlling motions of the actuator and the vibrator, a receiving unit receiving audio files each having a specific time sequence, a database storing the audio files, a sound sensor sensing ambient sounds to transmit corresponding signals, and a comparative unit comparing the signals transmitted by the sound sensor with the audio files stored in the database to locate a match audio file from the audio files, which is matched with the ambient sounds, and then transmit control signals to the control unit for enabling the control unit to control the actuator or the vibrator to move in accordance with the match audio file. As a result, the electric bed or chair moves along with the ambient sounds synchronously.

What is claimed is: 
     
         1 . An electric bed or chair movable along with ambient sounds, the electric bed or chair comprising:
 a frame structure comprising a base and a movable frame movably disposed on the base;   an actuator having two ends disposed with the base and the movable frame, respectively;   a vibrator disposed with the frame structure;   a control unit electrically connected with the actuator and the vibrator to control motions of the actuator and the vibrator;   a receiving unit receiving audio files each having a specific time sequence via a wire or wireless manner;   a database electrically connected with the control unit and the receiving unit for storing the audio files received by the receiving unit;   a sound sensor sensing ambient sounds and transmitting signals corresponding to the sensed ambient sounds; and   a comparative unit electrically connected with the sound sensor, the control unit and the database, the comparative unit comparing the signals transmitted by the sound sensor with the audio files stored in the database to locate a match audio file of the audio files, which is matched with the ambient sounds, and then transmit control signals to the control unit for enabling the control unit to control the actuator or the vibrator to move in accordance with audio signals of the match audio file.   
     
     
         2 . The electric bed or chair as claimed in  claim 1 , wherein the vibrator is disposed on the movable frame. 
     
     
         3 . The electric bed or chair as claimed in  claim 1 , wherein the audio files received by the receiving unit are audio files of movies, operas, songs or pieces of music. 
     
     
         4 . The electric bed or chair as claimed in  claim 1 , wherein the control unit controls the actuator to extend or retract and controls vibrating frequency and amplitude of the vibrator. 
     
     
         5 . The electric bed or chair as claimed in  claim 1 , further comprising a rocker mount disposed below the base, and a first drive device disposed between the rocker mount and the base; the first drive device is electrically connected with the control unit in a way that the control unit controls the first drive device to drive the base to swing relative to the rocker mount along a first curve. 
     
     
         6 . The electric bed or chair as claimed in  claim 5 , further comprising a support mount disposed below the rocker mount, and a second drive device disposed between the rocker mount and the support mount; the second drive device is electrically connected with the control unit in a way that the control unit controls the second drive device to drive the rocker mount to swing relative to the support mount along a second curve. 
     
     
         7 . The electric bed or chair as claimed in  claim 6 , wherein projection lines of the first curve and the second curve on a horizontal plane are perpendicular to each other.
