This invention relates to an electric bed using microphone to receive sound source for generating vibration accordingly, which includes a bed frame a power supply unit provided to the bed frame a driving source electrically connected to the power supply unit for driving the movable frame to change position with respect to the fixed base a controller electrically connected to the power supply unit and the driving source and having a microcomputer at least one microphone disposed to the bed frame and electrically connected to the microcomputer and a vibration device provided to the bed frame and electrically connected to the power supply unit. The vibration device is directly or indirectly electrically connected to the controller. The microcomputer judges the sound received by the microphone, and controls the vibration device to vibrate corresponding to the sound with specific frequency.一種以麥克風接收音源來對應產生震動的電動床,包含有:一床架;一電源供應單元,設於該床架;一驅動源,電性連接於該電源供應單元,用以驅使該活動架相對該固定座改變位置;一控制器,電性連接於該電源供應單元以及該驅動源,該控制器具有一微電腦;至少一麥克風,設於該床架且電性連接於該微電腦;以及一震動裝置,設於該床架且電性連接於該電源供應單元,該震動裝置直接或間接電性連接於該控制器;該微電腦係判斷該麥克風所接收到的聲音,並對應於特定頻率的聲音來控制該震動裝置產生震動。21‧‧‧電源供應單元26‧‧‧外部交流電源31‧‧‧驅動源41‧‧‧控制器42‧‧‧微電腦51‧‧‧麥克風61‧‧‧震動裝置62‧‧‧震動按摩馬達64‧‧‧震動墊66‧‧‧驅動電路
