a vibrator disposed in the inner accommodation of the cushion pack.

6 . The electric bed as claimed in claim 5 , wherein the vibrator comprises:

a base seat provided with a chamber at an inside of the base seat, and an opening in communication with the chamber and an outside of the base seat;

a magnetic member moveably disposed in the base seat and located in the chamber, the magnetic member being provided with a recessed ring portion; and

a cover including a cap body disposed on the base seat to close the opening, and a wire coil disposed with the cap body and extending into the recessed ring portion in a way that a gap is left between the wire coil and the magnetic member.

7 . The electric bed as claimed in claim 6 , wherein the magnetic member is disposed in the base seat by a ring mount; the ring mount comprises an outer ring connected with the base seat, an inner ring connected with the magnetic member, a middle ring located between the outer ring and the inner ring, a plurality of first ribs connected with the outer ring and the middle ring, and a plurality of second ribs connected with the middle ring and the inner ring; a gap is provided between the outer ring and the middle ring, and another gap is provided between the middle ring and the inner ring.

8 . The electric bed as claimed in claim 7 , wherein the vibrator further comprises a cushion pad disposed with the magnetic member; the base seat comprises a bottom portion at a side of the chamber that is remote from the opening; the cushion pad is disposed between the magnetic member and the bottom portion of the base seat.

9 . The electric bed as claimed in claim 6 , wherein the vibrator further comprises a cushion pad disposed with the magnetic member; the base seat comprises a bottom portion at a side of the chamber that is remote from the opening; the cushion pad is disposed between the magnetic member and the bottom portion of the base seat.

10 . The electric bed as claimed in claim 5 , wherein the cushion pack is disposed to the support member by two loop-and-hook fastening belts; the two loop-and-hook fastening belts each have a first end and a second end; the first ends of the two loop-and-hook fastening belts are disposed to the support member respectively, and the second ends of the two loop-and-hook fastening belts are engaged with each other and located at a bottom surface of the cushion pack.

11 . The electric bed as claimed in claim 5 , wherein the vibrator has an outer periphery encased by the cushion pack.

12 . The electric bed as claimed in claim 11 , wherein the cushion pack comprises an air permeable hole in communication with the inner accommodation and an outside of the cushion pack.

13 . The electric bed as claimed in claim 10 , wherein the cushion pack comprises an air permeable hole in communication with the inner accommodation and an outside of the cushion pack.

14 . The electric bed as claimed in claim 5 , further comprising a control unit electrically connected with the vibrator; the control unit transmits a sound signal to the vibrator such that the vibrator generates vibrations along with the sound signal.
