Description:
FIELD OF THE DISCLOSURE 
     The present disclosure relates to a vibration module and, more specifically, to a vibration module provided with a flow hole therein such that the body is pressurized using flow of air or a substance during a module vibration process to increase a body stimulation effect, the inside of the module can cooled down, and moreover, a substance such as drug is injected into the body or a substance (waste, fat, etc.) discharged from the body is discharged to the outside in order to improve a therapeutic effect. 
     Further, the present disclosure relates to a vibration module that can cool an LED or a high-frequency, low-frequency, or thermoelectric semiconductor and can function as a passage for water for cooling to give a function to a head that transmits vibration using the flow hole. 
     RELATED ART 
     A human body naturally ages over time, so pain is naturally generated and activity thereof is limited by injury due to partial degeneration. Further, various diseases such as brain damage, cardiosclerosis, arteriosclerosis, and arthritis are caused by limitation in activity accompanying industrial and technological development, and various complications due to not only simple damage such as a car accident, an industrial disaster, sports damage, activity damage, but stress, lack of exercise, and corpulence. 
     Not only medicines, but various body stimulation devices have been developed and used with functional food to treat pain, injury, corpulence, etc. that are generated by such natural phenomenon of a human body or social and cultural issues. In general, such stimulation devices generate vibration using a vibration module and a stimulator (a massage head, etc.) coupled to the vibration module vibrates and stimulates a human body, whereby relaxing muscles and reducing fatigue of nerves. A vibration type that uses a motor or a vibration speaker is applied to the vibration module for generating vibration. 
     Further, vibration is used not only for stimulation of a human body, but cultivation of cells and substances, which is included in the field of inducing changes of various substances, and even home appliances, so there is a need for an advanced vibration technology that can transmit quantified frequency and intensity of vibration and various voice signals. 
     According to a vibration module that uses a motor, not only it is difficult to adjust an amplitude and intensity, but the number of vibration is not variably transmitted, so the vibration type that uses a vibration speaker is being recently actively studied and developed. 
     A vibration module that uses a vibration speaker generally includes a bobbin having a coil wound thereon to which a current having sound information is applied, a magnet spaced apart from the coil and installed to surround the bobbin, and a vibration plate fixed to the bobbin. When a current having sound information is applied to the coil, a current flows in the magnetic field generated by the magnet and the bobbin with the coil wound thereon vibrates up and down in accordance with Fleming&#39;s left hand rule. In this process, the vibration plate fixed to the bobbin also vibrates and vibrates the surface of a stimulator being in contact with a human body, thereby periodically stimulating the human body. 
     Technologies are developed and applied to various fields through such complement of the vibration technology, but it is required to change the structure of a vibration module to combine other functions with the vibration function, so it is required to develop an improved vibration module to enter the market.

     Hereafter, exemplary embodiments of the present disclosure are described in more detail with reference to the drawings. 
       FIG. 1  is a schematic view illustrating a vibration module  10  according to an embodiment of the present disclosure and  FIG. 2  is an exploded perspective view of the vibration module  10 . Referring to  FIGS. 1 and 2 , a vibration module according to an embodiment of the present disclosure may include a vibration body  100 , a magnetic member  200 , a bobbin  300 , an elastic plate  310 , and a vibrator  500 . 
     The body  100  has an internal space. In detail, the body  100  may be formed in a hollow cylindrical shape with an open top. 
     The magnetic member  200  is disposed in the internal space of the body  100 . The magnetic member  200  may be a cylindrical permanent magnet. The magnetic member  200  is disposed at the center in the internal space of the body  100  and generates a magnetic field in which lines of magnetic force are generated around the magnetic member  200 . The magnetic member  200  may have a through-hole at the center to pass the vibrator  500  to be described blow. 
     The bobbin  300  has a hole such that at least a portion of the magnetic member  200  is inserted therein, and a coil  350  may be wound on the outer surface of the bobbin  300 . 
     The bobbin  300  may be formed in a cylindrical shape to correspond to the shape of the magnetic member  200  and may have a hole such that the magnetic member  200  is inserted therein. In detail, the bobbin  300  is positioned on the magnetic member  200  and at least a portion of the magnetic member  200  is inserted in the hole of the bobbin  300 . When a current is applied to the coil  350 , the bobbin  300  vibrates while moving up and down in the height direction of the magnetic member  200 . The bobbin  300  may be made of a nonmetallic material (aluminum, etc.). 
     The coil  350  is wound on the outer surface of the bobbin  300 . In detail, an upper protrusion  323  and a lower protrusion  321  may be formed on the top and the bottom of the bobbin  300 , respectively. The coil  350  is wound several times in the groove formed by the upper protrusion  323  and the lower protrusion  321  along the outer surface of the bobbin  300 . 
     Current signals are alternately supplied to the coil  350  from an external power supply, and the bobbin  300  with the coil  350  wound thereon moves up and down in accordance with the alternating current signals. In detail, a magnetic field is generated around the magnetic member  200  disposed in the body  100  and the bobbin  300  with the coil  350  wound thereon is disposed outside the magnetic member  200  and positioned in the magnetic field of the magnetic member  200 , whereby when a current signal is applied to the coil  350 , Lorentz force is generated and the bobbin  300  is moved. When negative and positive electrical signals are alternately applied to the coil  350 , the polarities of the coil  350  are alternately changed, so the bobbin  300  moves (vibrates) up and down. The intensity of the vibration is proportioned to the intensity of current and the number of winding of the coil  350 . 
     As the bobbin  300  moves up and down, the elastic plate  310  and the vibrator  500  that are coupled to the bobbin  300  move up and down, so the vibrator  500  vibrates. 
     A through-hole (not shown) may be formed at the center of the bobbin  300  to pass the vibrator  500  to be described blow. 
     A portion of the elastic plate  310  may be coupled to the top of the bobbin  300  and the other portion may be coupled to the top of the body  100 . In detail, the elastic plate  310  may be formed in a disc shape, the center portion of the elastic plate  310  is coupled to the bobbin  300 , and the edge of the elastic plate  310  is coupled to the body  100 . Coupling of a portion of the elastic plate  310  to the bobbin  300  and the other portion of the elastic plate  310  to the body  100  may be made by fasteners  130 . In the present disclosure, the fastener  130 , which is a part for fastening or fixing one component to another component, may be implemented in various types such as a bolt, a screw, and a rivet. Since a portion of the elastic plate  310  is coupled to the bobbin  300  that moves up and down and the other portion thereof is coupled and fixed to the body  100 , the elastic plate  310  is vibrated by movement of the bobbin  300  and the vibrator  500  coupled to the elastic plate  310  vibrates. 
     A through-hole (not shown) may be formed at the center of the elastic plate  310  to pass the vibrator  500 . 
     An elastic member  330  may be disposed between the elastic plate  310  and the top of the body  100 . In detail, a plurality of elastic members  330  is disposed on the top of the body  100  outside the elastic plate  310  and elastically supports the elastic plate  310 . The elastic members  300  maximize elasticity when the elastic plate  310  is vibrated by vibration of the bobbin  300 , thereby being able to maximize the vibration efficiency of the vibrator  500 . The elastic members  330  are disposed between the elastic plate  310  and the body  100 , and primarily absorb shock and transmit vibration to the elastic plate  310  when the bobbin  300  vibrates, thereby attenuating shock that is directly applied to the elastic plate  310 . Accordingly, it is possible to improve durability of the vibration module  10  by preventing damage to the elastic plate  310  due to fatigue. 
     The elastic members  330  may be C-shaped plate springs. In detail, the C-shaped plate spring may have a top, a bottom, and a bend, and the bend may be formed outward from the vibration module  10 . The top of the C-shaped plate spring is coupled to the elastic plate  310  by a fastener  130  and the bottom of the C-shaped plate spring is coupled to the top of the body  100  bay a fastener  130 . 
     When the elastic members  330  are C-shaped springs, up-down vibration of the bobbin  300  can be more effectively transmitted to the elastic plate  310 . Although the elastic members  330  are described as C-shaped plate springs in the present embodiment, the present disclosure is not limited thereto and the elastic members  300  may be S-shaped plate springs or the elastic members  330  may be spiral springs and may spirally transmit vibration to the elastic plate  310 . 
     When the elastic member  330  includes a C-shaped plate spring or an S-shaped plate spring, the elastic member may be individually integrally formed with the C-shaped plate spring or the S-shaped plate spring, and if necessary, they may be separately formed. 
     The vibrator  500  is fixed to the elastic plate  310  and has a flow hole  520  longitudinally formed therein. The vibrator  500  is fixed to the elastic plate  310  and applies vibration stimulation to a human body by vibrating with vibration of the elastic plate  310 . 
     The vibrator  500  may include a connection shaft  510 , a vibration head  530 , and a fixing plate  550 . The connection shaft  510  is formed in a circular pipe shape, has a flow hole  520  at the center, and passes through the elastic plate  310 , bobbin  300 , and the magnetic member  200 . The connection shaft  510  may be formed to pass through the bottom of the body  100 . 
     The vibration head  530  is formed over the connection shaft  510  and has a flow hole  520  at the center. The vibration head  530  can transmit vibration by coming in direct contact with a human body or can be coupled to another vibration device (a head for skin massage, a head for head skin massage, etc.) and can transmit vibration to the vibration device for various massages and stimulations. 
     The fixing plate  550  protrudes from the vibration head  530  or the connection shaft  510  and is coupled to the elastic plate  310  by fasteners  130 , thereby fixing the vibration head  530  to the elastic plate  310 . 
     A vibration head  530  disposed under other than above the connection shaft  510  may be additionally included, and in this case, the module can vibrate in two directions through the vibration heads  530  formed upper and lower potions. 
     A fixing plate for fixing the vibration head  530  formed at the upper portion to the elastic plate may be additionally included, and the way of fixing the elastic plate and the fixing plate is the same as the description about the elastic plate  310  and the fixing plate  550  included in the same way at the upper portion. 
     The flow hole  520  of the vibration head  530  and the flow hole  520  of the connection shaft  510  communicate with each other, so air can press a human body by flowing through the flow holes  520  or it is possible to cool the inside of the vibration module  10  using flowing air. Further, it is possible to inject substances such as drug into a human body or discharge substances (waste, fat, etc.) discharged from a human body out of the vibration module  10 . 
     In detail, the connection shaft  510  is inserted in the through-hole (not shown) of the elastic plate  310 , the through-hole (not shown) of the bobbin  300 , the through-hole (not shown) of the elastic member  200 , and the through-hole (not shown) of the body  100 , and is coupled to the elastic member  10 , the bobbin  300 , the magnetic member  200 , and the both  100  through theme, so a flow hole  520  of the vibration head  530  and the connection shaft  510  is formed through the vibration module  10 . As described above, it is possible to increase the human body stimulation effect and cool the inside of the vibration module  10  using the air that flows through the flow hole  520  formed through the vibration module  10 , and it is also possible to improve the treatment effect by injecting an external substance into a human body or discharge substances, which are discharged from a human body, out of the vibration module  10 . 
     An O-ring  110  may be disposed between the elastic members  330  and the body  100 . The O-ring  110  may be made of silicone and disposed between the bottoms of the elastic members  330  and the top of the body  100 , and can attenuate shock that is applied to the body  100  due to vibration of the bobbin  300 . 
     A shaft guide  230  may be disposed in the magnetic member  200 . In detail, the shaft guide  230  is formed in a longitudinally hollow circular pipe shape and is inserted in the through-hole (not shown) of the magnetic member  200 , and the connection shaft  510  is inserted in the longitudinal hole. The shaft guide  230  prevents the shaft  510  from tilting left and right by guiding the connection shaft  510  when the connection shaft  510  is moved up and down by vibration of the bobbin  300 , thereby improving the property of straight motion of the vibrator  500 . The shaft guide  230  may be made of a low-friction material such as a material containing graphite to prevent friction between the connection shaft  510  and the shaft guide  230 . 
     A coupling plate  210  is coupled to the magnetic member  200 . The coupling plate  210  has a shape that is substantially similar to the top of the magnetic member  200 , is disposed on the magnetic member  200 , and is installed adjacent to the bottom of the bobbin  300 . The coupling plate  210  prevents a loss of the magnetic field generated by the magnetic member  200  by inducing and focusing the magnetic force of the magnetic member  200  to the coil  350 . 
     A through-hole (not shown) is formed at the coupling plate  210  to communicate with the through-hole (not shown) of the magnetic member  200 , and the shaft guide  230  is inserted in the coupling plate  210  and the magnetic member  200  through the through-hole (not shown). 
     In detail, a stepped portion  231  protrudes from the top of the shaft guide  230  and a fixing groove  211  corresponding to the stepped portion  231  is formed at the coupling plate  210 . Accordingly, the stepped portion  231  of the shaft guide  230  is seated in the fixing groove  211  of the coupling plate  210 , whereby the shaft guide  230  is fixed to the coupling plate  210 . The shaft guide  230  guides the connection shaft  510  such that the vibrator  500  does not tilt when the vibrator  500  vibrates, and it is possible to prevent the problem of damage to the vibrator  500  due to accumulation of fatigue by preventing the vibrator  500  from tilting. 
     Hereafter, the vibration process of the vibration module  10  according to an embodiment of the present disclosure is described with reference to  FIGS. 3A and 3B . When a current is applied to the coil  350  positioned in the magnetic field of the magnetic member  200  in the initial state ( FIG. 3A ), the bobbin  300  is moved down by Lorentz force ( FIG. 3B ). Thereafter, when an opposite current is applied to the coil  350 , an opposite force is applied, so the bobbin  300  is moved up into the initial state ( FIG. 3A ). The bobbin  300  vibrates up and down by repeating this process, and the elastic plate  310  coupled to the bobbin  300  and the vibrator  500  coupled to the elastic plate  310  vibrate up and down. Since the vibrator  500  has a flow hole  520 , air can flow or external substances can be moved through the flow hole  520  during the vibration process. 
     As described above, since the vibration module  10  according to an embodiment of the present disclosure includes vibrator  500  having the flow hole  520  formed through the body  100 , the magnetic member  200 , the shaft guide  230 , and the bobbin  300 , when the vibration module  10  vibrates, air can flow through the flow hole  520  and press a human body or cool the inside of the vibration module  10 . Further, it is possible to inject a substance such as drug into a human body and it is possible to discharge substances, which are discharged from a human body, out of the vibration module  10 . 
     Further, since the C-shaped plate springs are disposed between the elastic plate  310  and the body  10 , movement of the bobbin  300  is more effectively transmitted to the elastic plate  310 , so the vibration effect of the vibration module  10  can be improved. 
     Further, since the shaft guide  230  that guides straight movement of the connection shaft  510  is disposed in the magnetic member  200 , the vibrator  500  vibrates without tilting when the bobbin  300  vibrates, whereby it is possible to prevent the problem of damage to the vibrator  500  due to accumulation of fatigue. 
     Although the present disclosure was described above with reference to exemplary embodiments, it should be understood that the present disclosure may be changed and modified in various ways by those skilled in the art, without departing from the spirit and scope of the present disclosure described in claims.
