The present invention relates generally to an electric device and more particularly, to a vibrator and an electric bed having the vibrator.
A vibrator, which is generally used as a massage device, can massage the tight muscle of the user through vibration to relieve discomfort, so that the user can relax the body and eliminate fatigue. Traditional vibrators mostly use motors to rotate an asymmetric block, such as eccentric wheel, to generate vibrations. As such, the vibrations generated by this type of vibrator are more divergent in direction, and the vibration force cannot be concentrated in a specific direction. Therefore, only a certain massage effect can be provided.
In order to provide consumers with the function of enjoying massage while resting, many electric beds have additionally provided vibrating massage functions. However, consumers have lost the freshness of the massage effect of traditional vibrators. Therefore, an issue of providing a novel vibrating massage experience to consumers that use electric beds needs to be solved by the industry. In another aspect, the conventional electric bed usually controls the vibrating massage device to synchronously operate with the speakers installed on the bed, thereby providing a synergy effect of sound and body sensation to the user. However, because the signal controlling the vibration motor is different from the signal controlling the speaker, an addition signal conversion is required for approaching synchronousness between the vibrator and the speaker. The problem of such design lies in that a complete synchronousness may not be achieved and the manufacturing cost may not be reduced due to the requirement of additional converter for performing signal conversion.
In view of above, how to provide a vibrator with a different vibrating effect compared to the traditional vibrator, and provide an electric bed with a novel vibrating massage effect with lower cost will be a key challenge to be overcome.
The present invention has been accomplished in view of the above-noted circumstances. It is an objective of the present invention to provide a vibrator, which can provide a novel vibrating massage effect.
It is another objective of the present invention to provide an electric bed having the vibrator, which can provide a massage function different from that of the conventional electric bed, and can output sound and vibration synchronously in association with a stereo device with low cost.
To attain the above objective, the present invention provides a vibrator comprising a base seat, a magnetic member, and a cover. The base seat is provided with a chamber at an inside thereof, and an opening in communication with the chamber and an outside of the base seat. The magnetic member is moveably disposed in the base seat, located in the chamber, and provided with a recessed ring portion. The cover includes 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. By means of reciprocating motions of the magnetic member relative to the wire coil, a unidirectional vibration can be produced, thereby providing a novel vibrating massage effect.
To attain the above-mentioned another objective, the present invention provides an electric bed comprising a fixation frame, a moveable frame, an actuator, a support member, a cushion pack, and a vibrator. The movable frame is moveably disposed to the fixation frame. The actuator is connected between the fixation frame and the moveable frame to drive the moveable frame to move relative to the fixation frame. The support member is disposed to one of the fixation frame and the moveable frame and provided with a support surface, a bottom surface opposite to the support surface, and a hollow portion penetrating through the support surface and the bottom surface. The cushion pack is disposed to the support member in a way that the cushion pack is inserted in the hollow portion of the support member. The cushion pack is provided with a top surface that is flesh with or protrudes upwardly over the support surface, and an inner accommodation. The vibrator is disposed in the inner accommodation of the cushion pack. The position of the moveable frame relative to the fixation frame can be adjusted by controlling the actuator in accordance with actual need to achieve the goal of providing a comfortable lying effect. Further, by transmitting a sound signal to actuate the vibration, a vibrating effect in synchronousness with sound can be provided.
The present invention will become more fully understood from the detailed description given herein below and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
The structure and technical features of the present invention will be detailedly described hereunder by an embodiment and accompany drawings. As shown in
The base seat 11 includes a chamber 111, an opening 112, and a bottom portion 113. The chamber 111 is provided at an inside of the base seat 11 for accommodating the magnetic member 12, the opening 112 is in communication with the chamber 111 and an outside of the base seat 11, i.e., ambient environment, and the bottom portion 113 is located at a side of the chamber 111, which is remote from the opening 112.
The magnetic member 12 is moveably disposed in the base seat 11, located in the chamber 111, and provided with a recessed ring portion 121. The magnetic member may be (but not limited to) a permanent magnet.
In this embodiment, the magnetic member 12 is disposed in the base seat 11 by a ring mount 15. The ring mount 15 comprises an outer ring 151, an inner ring 152, a middle ring 153, a plurality of first ribs 154, and a plurality of second ribs 155. The outer ring 151 and the inner ring 152 are connected with the base seat 11 and the magnetic member 12, respectively. The middle ring 153 is located between the outer ring 151 and the inner ring 152. The first ribs 154 are used to connect the outer ring 151 with the middle ring 153, and the second ribs 155 are used to connect the middle ring 153 with the inner ring 152. Further, the first ribs 154 and the second ribs 155 are alternately arranged on the middle ring 153, and the ring mount 15 is made of elastic material and configured in a way that the inner ring 152 and the outer ring 151 can move in an axial direction relative to each other, resulting in that the magnetic member 12 can reciprocatingly move up and down relative to the base seat 11. Moreover, a gap 156 is provided between the outer ring 151 and the middle ring 153, and another gap 157 is provided between the middle ring 153 and the inner ring 152, such that the outer ring 151, the inner ring 152 and the middle ring 153 will not rub with each other when the magnetic 12 is moving, thereby ensuring smooth movement of the magnetic member 12.
The cover 13 includes a cap body 131 and a wire coil 132. The cap body 131 is mounted to the base seat 11 by screws (not shown) to close the opening 112. The wire coil 132 is mounted to the cap body 131 and extends into the recessed ring portion 121 of the magnetic member 12 in such a way that a gap 122 is left between the wire coil 132 and the magnetic member 12, thereby ensuring that the magnet member 12 will not contact and rub the wire coil 132 while the magnetic member 12 is moving.
The cushion pad 14 is mounted to a bottom surface of the magnetic member 12 and located between the magnetic member 12 and the bottom portion 113 of the base seat 11. There is a gap left between the cushion pad 14 and the bottom portion 113, thereby avoiding the magnetic member 12 from direct impact with the bottom portion 113 to produce noise.
When the vibrator 10 is in use, a signal, such as a sound signal, is inputted into the wire coil 132. As soon as the wire coil 132 receives the signal, a magnetic force is produced to drive the magnetic member 12 to axially and reciprocatingly move relative to the wire coil 132. Because the magnetic member 12 has a certain weight, the vibrator 10 will produces unidirectional vibrations due to the reciprocating movement of the magnetic member 12.

The moveable frame 22 may also be a rectangular rack, which is moveably mounted on the fixation frame 21. For example, the moveable frame 22 may be mounted on the fixation frame 21 by one or more pivotal members, such that the moveable frame 22 is swingable relative to the fixation frame 21. The moveable frame 22 may comprises a first moveable part (the left part shown in
The actuator 23 is connected between the fixation frame 21 and the moveable frame 22 to drive the moveable frame 22 to move relative to the fixation frame 21, such that the position of the moveable frame 22 relative to the fixation frame 21 can be adjusted. The actuator 23 comprises a motor and a telescope rod drivenable by the motor. By means of operating the motor to drive the telescope rod to extend or retract, the moveable frame 22 is driven to change its position. However, the way of driving the moveable frame 22 is not limited to this embodiment.
The support member 24 is configured to be mounted to the fixation frame 21 or the moveable frame 22. In this embodiment, the support member 24 is mounted to the moveable frame 22 for illustrative purpose. The support member 24 has a support surface 241, a bottom surface 242, and a hollow portion 243. The support surface 241 is used to support a mattress or a user, thereby enabling the user to lie or lean thereon. The bottom surface 242 is opposite to the support surface 241. As shown in
The cushion pack 25 is mounted to the support member 24 and inserted into the hollow portion 43. Specifically, the cushion pack 25 is made by a foam material or elastic material. The cushion pack 25 is mounted to the support member 24 by two loop-and-hook fastening belts 27. The two loop-and-hook fastening belts 27 each have a first end and a second end opposite to the first end. The first ends of the two loop-and-hook fastening belts 27 are fixed to the bottom surface 242 of the support member 24, respectively. The second ends of the two loop-and-hook fastening belts 27 are fixedly engaged with each other and located at a bottom surface 252 of the cushion pack 25. In another embodiment, the cushion pack 25 may be fixedly mounted to the support member 24 by another feasible way. The cushion pack 25 is provided with a top surface 251 that is flesh with or protrudes upwardly over the support surface 241. As shown in
As shown in
The vibrator 10 is received in the inner accommodation 253 of the cushion pack 25. The outer periphery of the vibrator 10 is completely encased by the cushion pack 25, such that the vibrations produced by the vibrator 10 can be used to massage the user. During operation of the vibrator 10, the temperature of the vibrator 10 may raise. The air permeable holes 254 will be helpful for heat dissipation, thereby preventing the vibrator 10 from overheat.
In view of the above illustration, a user may lie on the support member 24 of the electric bed 10 and controls the actuator 23 in accordance with his/her need to adjust the moveable frame 22 to a desired position relative to the fixation frame 21. Further, by means of inputting a control signal into the vibrator 10, the user may operate the vibrator 10 to vibrate in accordance with the inputted signal. For example, sound signal or music signal having various melodies may be used as the control signal to produce new somatosensory massage different from the past. Further, by means of adjusting the frequency and amplitude of the inputted signal, the frequency and magnitude of the vibrations can be controlled. As a result, the vibrator 10 of the present invention can provide new, various vibrating effects.
Based on the technical features of the present invention, various modifications to the vibrator 10 may be made. For example, the vibrator 10 may be configured without the cushion pad 14, the structure of the ring mount 15 may be modified to a feasible way allowing smooth movement of the magnetic member 12.
