Abstract: The present invention provides an air massage device for a bed. The air massage device includes at least one air wave generator disposed on the bed. The air wave generator includes a shell, a permanent magnet disposed in the shell, a coil electromagnet movably disposed in the shell and a membrane attached to the coil electromagnet. When the coil electromagnet is powered by an alternating current, the coil electromagnet moves reciprocatingly relative to the permanent magnet along with the membrane so that the membrane generates an air wave which is adapted to massage people on the bed.

Abstract: A synchronous loudspeaking system comprises a first Bluetooth receiver, a first processor, a first speaker, a second Bluetooth receiver, a second processor and a second speaker. The first Bluetooth receiver receives a first signal. The first processor electrically connects to the first Bluetooth receiver. The first speaker has a first input terminal electrically connected to the first processor, and a first output terminal. The second Bluetooth receiver optionally receives a second signal. The second processor electrically connects to the second Bluetooth receiver. The second speaker has a second input terminal electrically connected to the second processor and optionally connected to the first output terminal, and a second output terminal. The two speakers sound synchronously when the second input terminal and the first output terminal is electrically connected.

Abstract: An electric folding bed includes a base having a load-bearing element for supporting hips of a user and at least a track extending along a head-to-foot axis of the bed, a telescopic actuator having a body pivotally attached to the base and a telescoping element linearly moveable relative to the body along the head-to-foot axis substantially, a connecting unit pivotally connected with the telescoping element, a backboard fastened to the connecting unit for the user to lean thereon, at least a supporting element pivotally attached to the base and the connecting unit, and at least a moving element disposed to the track and pivotally attached to the connecting unit. The telescoping element drives the connecting unit and the backboard to swing up and displace away from the load-bearing element. Therefore, the electric folding bed can avoid user's uncomfort and injury when the user sits up.

Abstract: A bracket, which is adapted for retaining a mattress, includes two hinge bases for being mounted on a bed frame, two rotating members and a connector. Each of the rotating members has a pivot and a first coupling portion extending from the pivot and being substantially perpendicular to the pivot. The pivots are respectively connected with the hinge bases rotatably. The connector has a transverse portion and two second coupling portions respectively provided at two ends of the transverse portion and coupled with the first coupling portions. As a result, the connector can be easily dismounted from and mounted to the rotating members. When the connector is dismounted from the rotating members, the bed frame is conveniently wrapped and transported.

Abstract: An easy-installable bracket for retaining a bed mattress is provided. The bracket is adapted to be disposed on a bed frame having a head portion and a feet portion. The bracket includes two seats and a bracket member. Each of the seats has a bottom plate for fixed at the feet portion of the bed frame, and an arcuate portion extended from the bottom plate. Two passages are respectively defined between the arcuate portions of the seats and the feet portion. The bracket member has a vertical portion, two front-extending sections respectively extended from two bottom ends of the vertical portion toward the head portion of the bed frame, and two parallel rear-extending sections respectively extended from distal ends of the front extending sections toward the feet portion. The rear-extending sections are slidably received in the passages respectively.

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.
