The human body stimulation device 1 according to one embodiment may include massage applicators for massaging a body of a user. For example, the human body stimulation device 1 may include massage applicators such as air cells, rollers, and acupressure protrusions in the backrest 20, the seat 30, and/or the arm/leg unit 40.
The human body stimulation device 1 according to one embodiment may massage the body of the user through the human body stimulation unit 10. For example, the human body stimulation device 1 may massage the body of the user through the human body stimulation unit 10 installed inside the backrest 20. For example, the human body stimulation unit 10 may provide various stimuli for a body massage to a body, such as tapping, kneading, and pressing the body. Specifically, the human body stimulation unit 10 may drive an arm 200 through the driving unit 100 to physically massage a body through a massage ball 400 or a sonic vibration module 300 disposed at one end portion of the arm 200.
In addition, the human body stimulation unit 10 may have a function of providing a sonic vibration massage on a body. For example, the human body stimulation unit 10 may perform a sonic vibration massage by transmitting sonic vibration to the body of the user through the sonic vibration module 300 disposed at one end portion of the arm 200. Here, the human body stimulation unit 10 may perform a sonic vibration massage on a body and simultaneously drive the arm 200 through the driving unit 100 to physically massage the body through the sonic vibration module 300 disposed at one end portion of the arm 200.
Sonic vibration may be a type of vibration and may refer to vibration generated based on the generation of sound waves. The generation of sonic vibration will be described below. A sonic vibration massage means that sonic vibration is transmitted to the body of the user to obtain a massage effect. When an appropriate sonic vibration massage is performed on the user, the user may obtain effects of improving health, such as effects of lessening a fatigue feeling, improving blood circulation, and relieving stress.
The human body stimulation unit 10 may be movable to massage a body at a various positions. For example, the human body stimulation unit 10 may include the driving unit 100 to move along the backrest 20 of the human body stimulation device 1 and massage a back of the user at various positions.
The human body stimulation device 1 may include a controller 600 (not shown) which controls each component of the human body stimulation device 1 or processes and calculates various types of information. For example, the controller 600 may be included in the human body stimulation unit 10 to control the human body stimulation unit 10 to provide a massage.
The controller 600 may be provided in the form of an electronic circuit which physically processes an electrical signal. The controller 600 may be a concept physically including a plurality of controller 600 as well as a single controller 600. For example, the controller 600 may be provided as one or more processors mounted on one computing device.
Examples of the controller 600 may include a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processor (DSP), a state machine, an application specific integrated circuit (ASIC), a radio-frequency integrated circuit (RFIC), and a combination thereof.
However, the human body stimulation device 1 shown in
Hereinafter, a human body stimulation unit 10 according to one embodiment will be described with reference to
Referring to
The driving unit 100 may be configured to move the human body stimulation unit 10 itself. For example, the driving unit 100 may move the human body stimulation unit 10 upward or downward along a guide rail (not shown) installed in a backrest 20. Specifically, the driving unit 100 may allow teeth to be engaged with the guide rail so as to be movable along the guide rail and may rotate the teeth using a lifting motor (not shown) to move the teeth along the guide rail.
In addition the driving unit 100 may be configured to move the components of the human body stimulation unit 10. For example, the driving unit 100 may move the arm 200 in various directions to tap, knead, or press a body. Here, the sonic vibration module 300 and/or a massage ball 400 may be connected to one end portion of the arm 200, may come into contact with a body of a user according to the movement of the arm 200, and may tap or knead the body.
The driving unit 100 may provide a tapping massage to a body by moving the arm 200.
For example, for the tapping massage, the driving unit 100 may include a holder 110 for mounting the arm 200, a link for receiving power from a rotating body 111 to move the holder 110 in a certain route range, and a tapping motor 112 for rotating the rotating body 111. Specifically, the tapping motor 112 may rotate the rotating body 111, a force according to the rotation of the rotating body 111 may be transmitted to the link, and the link may move one end of the connected holder 110 within a certain motion route to move the arm 200. Finally, the sonic vibration module 300 and the massage ball 400 may move the arm 200 forward or backward in a Z-axis direction, may move at a certain motion angle, and may come into contact with a body to tap the body. Here, when a speed of the rotating body 111 increases, a speed of tapping the body may also increase.
The driving unit 100 may provide a kneading massage to a body by moving the arm 200.
For example, for the kneading massage, the driving unit 100 may include a kneading motor 120 (not shown), an eccentric rotating body 121, and a support shaft 122. Specifically, as the kneading motor 120 is driven, the eccentric rotating body 121 installed on the support shaft 122 may rotate eccentrically to move the arm 200 such that the sonic vibration module 300 and the massage ball 400 perform a kneading operation. Here, due to the eccentric rotation of the eccentric rotating body 121, the kneading operation may include all of movement in upward/downward movement in a Y-axis direction, forward/backward movement in the Z-axis direction, and leftward/rightward movement in an X-axis direction so that a route draws a circular motion or an elliptical motion. Accordingly, a contact angle of the massage ball 400 and/or the sonic vibration module 300 in contact with a body may also be changed.
That is, the driving unit 100 may drive the arm 200 to move the sonic vibration module 300 and/or the massage ball 400 within a preset rotation angle range. For example, the sonic vibration module 300 may move along a certain route by changing an inclination angle of a central axis 520 of the sonic vibration module 300. A rotation angle may be an angle inclined while the sonic vibration module 300 and/or the massage ball 400 rotates and moves from an original position thereof and may indicate an angle at which the sonic vibration module 300 and/or the massage ball 400 is inclined by the driving unit 100.
Of course, the driving unit 100 is not limited to the above description and may be driven in other ways.
The reference axis 500 may be the central axis 520 of the sonic vibration module 300 when the sonic vibration module 300 is positioned at the reference point and may be an axis perpendicular to a reference plane 510. The central axis 520 of the sonic vibration module 300 may coincide with the central axis 520 of a head when the head is positioned at an exact center of the sonic vibration module 300. The reference plane 510 may be a floor plane on which the sonic vibration module 300 is supported when the sonic vibration module 300 is positioned at the reference point. The rotation angle α, which is an angle at which the sonic vibration module 300 is inclined, may refer to an angle between the reference axis 500 and the central axis 520 of the sonic vibration module 300.
Therefore, referring to
Referring to
As described above, the rotation angle α may be measured not only by using the sonic vibration module 300 but also by using an angle at which the massage ball 400 or the arm 200 is inclined by the driving unit 100, and the present invention is not limited thereto.
The arm 200 may be connected to the driving unit 100. For example, the arm 200 may be mounted on a driving device through a hinge. Here, the arm 200 may be connected to the driving unit 100, and when the driving unit 100 is driven, the arm 200 may move and come into contact with a body to perform a massage such as tapping or kneading.
The arm 200 may include an upper portion 210 and a lower portion 220 which move in conjunction with each other. For example, as the upper portion 210 approaches the body of the user, the lower portion 220 may also approach the body of the user.
The arm 200 may be connected to the massage ball 400 and/or the sonic vibration module 300. For example, the massage ball 400 may be installed at the upper portion 210 of the arm 200, and the sonic vibration module 300 may be installed at the lower portion 220 of the arm 200. Here, the upper portion 210 of the arm 200 connected to the massage ball 400 may be configured to provide a massage such as tapping or kneading to the body of the user through the massage ball 400, and the lower portion 220 of the arm 200 connected to the sonic vibration module 300 may be configured to provide a sonic vibration massage to the body of the user through the sonic vibration module 300.
Of course, the arm 200 is not limited to the above description. The arm 200 may be connected to the massage ball 400 and/or the sonic vibration module 300 in another form in which the upper portion 210 of the arm 200 is connected to the sonic vibration module 300, and the lower portion 220 of the arm 200 is connected to the massage ball 400.
The sonic vibration module 300 may be an applicator for performing a sonic vibration massage function. For example, the sonic vibration module 300 may generate sonic vibration and may be in direct/indirect contact with a body to transmit the generated sonic vibrations to the body. Here, sonic vibration used for a sonic vibration massage may be sonic vibration in an audible frequency range. Specifically, the sonic vibration used for the sonic vibration massage may have a frequency range of 10 Hz to 300 Hz.
The sonic vibration module 300 may be an applicator for performing a function of a general massage which may be referred to as a motion massage. For example, the sonic vibration module 300 may be connected to the arm 200 and may perform a general massage such as a tapping or kneading massage on the body of the user in synchronization with movement of the arm 200. In the present specification, the term “motion massage” may refer to a generally performed massage and may refer to an act of stimulating a body part such as repeatedly pressing the body part for a certain time or more or shaking the body part.
According to one embodiment, the sonic vibration module 300 may provide a tapping massage, a kneading massage, or the like to a body and simultaneously provide a vibration massage. As an example, a human body stimulation device 1 may provide a multi-massage in which the sonic vibration module 300 outputs sonic vibration to a body while providing a kneading massage by moving the sonic vibration module 300. As another example, the human body stimulation device 1 may provide a multi-massage in which the sonic vibration module 300 outputs sonic vibration to a body while providing a tapping massage by moving the sonic vibration module 300.
According to one embodiment, the sonic vibration module 300 may be installed at the lower portion 220 of the arm 200 and may be installed downward at a certain angle from the arm 200. For example, the sonic vibration module 300 may be installed downward at an angle of 5° to 20° from the arm 200.
This is to prevent contact between the head of the sonic vibration module 300 and a body from becoming difficult due to the sonic vibration module 300 of the lower portion 220 interlocked with the upper portion 210 being inclined upward from the arm 200 as an applicator of the upper portion 210 of the arm 200 comes into contact with a body of a user to press the body.
The certain angle may be related to movement of the lower portion 220 when the sonic vibration module 300 is moved by the driving unit 100. For example, the certain angle may be related to an angle at which the lower portion 220 is inclined when the sonic vibration module 300 is moved forward to or backward from the body of the user by the driving unit 100. Here, when the sonic vibration module 300 is moved forward to or backward from the body of the user by the driving unit 100, as an angle at which the lower portion 220 is inclined is increased, the certain angle may also be increased. Of course, the certain angle is related not only to an angle at which the lower portion 220 is inclined by the driving unit 100 but also to a position of the lower portion 220 being changed as the sonic vibration module 300 is moved forward or backward, but the present invention is not limited thereto.
Thus, it is possible to assist the sonic vibration module 300 in maintaining body contact during a massage, increase a life time of the human body stimulation device 1 by preventing the sonic vibration module 300 from performing an idle operation, also reduce noise generation, and continuously provide a vibration massage to a body.
The sonic vibration module 300 will be described in detail below.
The massage ball 400 may be an applicator for performing a general massage function. For example, the massage ball 400 may be connected to the arm 200 and may perform a general massage such as a tapping or kneading massage on the body of the user in synchronization with the movement of the arm 200.
The massage ball 400 may have a shape, material, or the like for performing a massage. For example, the massage ball 400 may have a curved shape and may have an elliptical shape or a spherical shape in a plan view. For another example, the massage ball 400 may be made of an elastic material such as rubber or silicone for a soft massage.
Of course, the human body stimulation unit 10 is not limited to that described above with reference to
The human body stimulation unit 10 is not limited to the above description, and the sonic vibration module 300 may be implemented in another form without being mounted on an arm 200.
As an example, the sonic vibration module 300 may be mounted on a base of the human body stimulation unit 10. Here, the sonic vibration module 300 may not move through the arm 200 but may move by using an air bag connected to the sonic vibration module 300. Specifically, air may be injected into the airbag connected to the sonic vibration module 300 so that the sonic vibration module 300 may come into contact with a body of a user, or a direction of the airbag may be changed so that the sonic vibration module 300 may move within a preset rotation angle range. As another example, the sonic vibration module 300 may be installed inside an airbag installed in the human body stimulation unit 10.
According to some embodiments, components may be added to or excluded from the human body stimulation unit 10 of
A sonic vibration module 300 will be described with reference to
The sonic vibration generator 310 may generate sonic vibration. For example, the sonic vibration generator 310 may include devices (not shown) for reproducing a sound source therein, for example, a codec, an amplifier, and a speaker, and may generate vibration using a sound source. Here, the sonic vibration generator 310 may output sonic vibration corresponding to a sound source. The sonic vibration generator 310 will be described in detail below.
The head 320 may transmit the generated sonic vibration to the body of the user. For example, the head 320 may be connected to the sonic vibration generator 310 and may transmit the sonic vibration transmitted from the sonic vibration generator 310 to the body of the user in direct/indirect contact therewith. Here, the head 320 may be made of various materials, for example, a silicone material, a wood material, a plastic material, and a metal material. The head 320 may transmit stronger sonic vibration to the user by locally transmitting the sonic vibration to the body of user.
The housing 330 may accommodate the sonic vibration generator 310. For example, the housing 330 may surround the sonic vibration generator 310 therein and may prevent an external force due to a massage from being applied to the sonic vibration generator 310. Thus, the durability of the sonic vibration module 300 can be improved.
The housing 330 may at least partially accommodate the head 320. For example, the housing 330 may surround a portion of the head 320 connected to the sonic vibration generator 310 and may expose a portion of the head 320 through a pierced hole such that the head 320 may be in direct/indirect contact with the body of the user. Since the housing 330 exposes only a portion of the head 320, the housing 330 may prevent the head from being tilted and damaged due to an external force applied from a side surface of the head 320.
The housing 330 may be implemented in various shapes. For example, a portion of the housing 330 in contact with a body may be provided as a round surface to be in smooth contact with the body. Here, a hole through which the head 320 passes may be formed in the housing 330 such that a portion of the head 320 may be exposed to the outside. Specifically, in order to prevent the head 320 from being heavily tilted due to an external force, a buffer member 331 made of a silicone material or the like may be provided in a space between the head 320 and the hole of the housing 330.
Referring to
The lower plate 311 may have a space, in which the magnetic body 312 is accommodated, formed therein. For example, the lower plate 311 may have a cylindrical shape with an open upper portion, and the magnetic body 312 may be installed therein. The lower plate 311 may be used to form a magnetic path of a magnetic field formed by the magnetic body 312 and the coil 314.
The magnetic body 312 may be installed inside the lower plate 311 to be spaced apart from the lower plate 311. For example, a groove, in which the magnetic body 312 is fixedly installed, may be formed in a bottom surface of the lower plate 311, and an inner surface of the lower plate 311 may be spaced a certain interval apart from an outer peripheral surface of the magnetic body 312 installed in the groove.
The magnetic body 312 may be, for example, a permanent magnet that is a ferromagnetic body such as a neodymium magnet. When power is applied to the sonic vibration module 300 to magnetize the coil 314, the magnetic body 312 may be used to generate an attractive force and a repulsive force and generate vibration. Here, the magnetic body 312 may be positioned in a lower surface of the bobbin 313, and when the coil 314 wound on the bobbin 313 is magnetized, the magnetic body 312 may generate an efficient magnetic field to generate a mutual attractive force and a repulsive force and generate stable vibration.
The middle plate 315 may be installed on the magnetic body 312 to prevent loss of a magnetic field generated by the magnetic body 312. For example, the middle plate 315 may have a shape similar to that of an upper surface of the magnetic body 312 and may be installed between an upper portion of the magnetic body 312 and a lower portion of the bobbin 313 to induce a magnetic force of the magnetic body 312 to be concentrated on the coil 314. Here, a magnetic fluid (not shown) may be applied to an outer diameter portion of the middle plate 315 to form a magnetic field.
The bobbin 313 may be made of a material not having magnetism (for example, aluminum material or the like) and may be installed inside the lower plate 311. For example, the bobbin 313 may be installed inside the lower plate 311 in a state in which the voice coil 314 is wound thereon. The bobbin 313 may correct physical eccentricity generated due to body contact.
The bobbin 313 is formed in a cylindrical shape of which a side surface is open between an upper portion and a lower portion. A radius of an upper surface and a lower surface of the bobbin 313 may be greater than a radius of the side surface thereof, and the lower portion of the side surface may extend outward so that the bobbin 313 may include the lower surface facing the upper surface. Here, the coil 314 may be wound on the side surface of the bobbin 313, and the coil 314 may be guided by the upper surface and the lower surface of the bobbin 313 having the radius greater than the radius of the side surface of the bobbin 313. Thus, the bobbin 313 may guide the coil 314 to be stably installed at an outer peripheral portion thereof, thereby preventing the coil 314 from being separated.
The bobbin 313 may be connected to the head 320. For example, the bobbin 313 may be coupled to the head 320 through a coupling hole formed in a central portion of the upper surface thereof.
The bobbin 313 may include a heat radiation hole for radiating heat. For example, the bobbin 313 may radiate generated when vibration is generated through one or more heat radiation holes formed in the upper surface thereof and may reduce noise generated, when vibration is generated, together with a heat radiation effect.
The upper ring 316 may be disposed on the lower plate 311 and may be coupled to the first leaf spring 317 and the second leaf spring 318. For example, the upper ring 316 may be coupled to the first leaf spring 317 and the second leaf spring 318 through a plurality of coupling protrusions formed on an upper surface thereof. Here, the coupling protrusions may be coupled to dampers formed in the first and second leaf springs 317 and 318. In addition, upper and lower portions of the coupling protrusion coupled to the damper are supported through an elastic member (for example, a silicone washer or the like), thereby preventing vibration from being attenuated. The upper ring 316 can form a space in which the leaf spring may move upward and downward according to the characteristics of generated sonic vibration so that the durability of the sonic vibration module 300 can be improved.
The leaf springs 317 and 318 may be installed on the bobbin 313. For example, the leaf springs 317 and 318 may be installed on the bobbin 313 and may act like a speaker to generate vibration when a sound source is applied. Specifically, the leaf springs 317 and 318 may generate sonic vibration in a vertical direction using a magnetic field generated by an interaction between the magnetic body 312 and the coil 314.
The leaf springs 317 and 318 may be made of various materials suitable for generating sonic vibration. As an example, the leaf springs 317 and 318 may be made of a metal material such as copper or STS301.
The leaf springs 317 and 318 may have the dampers formed at an edge thereof to maximize a vibration force. For example, the leaf springs 517 and 518 may include one or more dampers which are formed in a shape elongated radially in a shape of a curved band at the edge thereof and which have coupling holes for screw coupling formed in end portions thereof. Here, the dampers may be coupled to the coupling protrusions of the upper ring 316 through the coupling holes. Of course, the shape of the damper is not limited thereto, and as an example, the damper may be formed in various ways in which an outer peripheral portion of the damper is formed in a circular structure and the end portion of the damper is disposed between fixing points.
The leaf springs 317 and 318 may include heat radiation holes for radiating heat. For example, the leaf springs 317 and 318 may radiate heat generated when vibration is generated through one or more heat radiation holes formed in an upper surface thereof and may reduce noise that is generated, when vibration is generated, together with a heat radiation effect.
The leaf springs 317 and 318 may transmit generated vibration to the outside. For example, the leaf springs 317 and 318 may be connected to the head 320 and may transmit generated sonic vibration to the head 320. Here, since sonic vibration generated in central portions of the leaf springs 317 and 318 is the strongest, the leaf springs 317 and 318 may be coupled to the head 320 through coupling holes formed in the central portions of the leaf springs 317 and 318, thereby transmitting the generated sonic vibration to the head 320.
The leaf springs 317 and 318 may be installed doubly on the bobbin 313 to improve durability. For example, the first leaf spring 317 and the second leaf spring 318 may be installed to overlap each other on the bobbin 513, but the present invention is not limited thereto. The first leaf spring 517 and the second leaf spring 518 may be installed apart from each other by a certain distance. In addition, the first leaf spring 317 and the second leaf spring 318 may be implemented to have the same material and/or shape, but the present invention is not limited thereto. The first leaf spring 317 and the second leaf spring 318 may be implemented to have different materials and/or shapes. In addition, the leaf springs 317 and 318 are not limited to the above description and may be implemented as one leaf spring without being doubly installed.
The head 320 may receive the generated vibration to transmit the vibration to the outside. For example, the head 320 may be connected to the leaf springs 317 and 318 and the bobbin 313 and may receive sonic vibration generated from the leaf springs 317 and 318 and/or the bobbin 313 to transmit the received sonic vibration to the body of the user in direct/indirect contact therewith. Specifically, a lower portion 322 of the head 320 may be inserted into the coupling holes formed in the leaf springs 317 and 318 and the coupling hole formed in the bobbin 313 and coupled to the leaf springs 317 and 318 and/or the bobbin 313. Here, a structure to be screw-coupled to the head 320 may be formed inside the coupling holes. Therefore, since the head 320 is connected to the leaf springs 317 and 318, when the leaf springs 317 and 318 generate vibration in the vertical direction by acoustic pressure, the head 320 may transmit the vibration to a body.
The head 320 may have various shapes according to a massage part or a stimulation part of a body or purpose of use. For example, the head 320 may be provided in various shapes such as a plate shape, a plate shape having protrusions, a cylindrical shape, a rectangular parallelepiped shape, and a spherical shape according to a massage part and a purpose of a massage.
According to one embodiment, the head 320 may include the lower portion 322 and an upper portion 321 of the head 320. For example, the lower portion 322 and the upper portion 321 of the head 320 may be integrally formed, the lower portion may serve as a connection portion that connects the upper portion and the sonic vibration generator 310, and the upper portion may serve as a hitting portion that applies vibration. Specifically, the lower portion 322 of the head 320 may be connected to the sonic vibration generator 310, and sonic vibration generated from the sonic vibration generator 310 may be transmitted to the upper portion 321 of the head 320. The upper portion 321 of the head 320 may apply the received sonic vibration to the body of the user.
As an example, the upper portion 321 of the head 320 is formed in a shape with a round surface including a spherical or hemispherical shape, and the lower portion 322 of the head 320 may be formed in a cylindrical shape to be inserted into the coupling holes formed in the leaf springs 317 and 318 and the coupling hole formed in the bobbin 313. However, the shape of the head 320 is not limited thereto, and as an example, the upper portion 321 of the head 320 may be implemented in various shapes such as a plate shape or a plate shape having protrusions formed thereon. However, the lower portion 322 and the upper portion 321 of the head 320 are not limited to the above description and may be implemented in other forms.
The head 320 may have a detachable structure. For example, the head 320 may include a coupling portion that is attachable to or detachable from the leaf springs 317 and 318 and may be replaced with another head 320 through the coupling portion.
In addition, although not shown, the sonic vibration module 300 may include a connection member, and the connection member may be connected to the bobbin 313 and disposed on the leaf springs 317 and 318 to serve to facilitate the attachment or detachment of various heads 320.
Referring to
The housing 330 may be in contact with the body of the user to prevent an external force from being excessively applied to the sonic vibration generator 310 positioned therein due to a massage. Specifically, when an external force is applied to the sonic vibration module 300, the leaf springs 317 and 318 and the bobbin 313 are pushed downward by the external force, and thus the head 320 is also pushed downward. In this case, the housing 330 may disperse the external force and may prevent the head 320 from being lowered by a certain level or more.
In addition, the housing 330 may prevent the head 320 from being excessively tilted and damaged due to an external force applied from a side surface of the head 320. Here, a portion of the housing 330 in contact with a body may be provided as a round surface to be in smooth contact with the body.
The exposed portion of the head 320 may be in direct/indirect contact with the body of the user and may transmit vibration to the body of the user. The head 320 may locally transmit sonic vibration to the body to improve an effect of a sonic vibration massage.
However, when the head 320 is not sufficiently exposed from the housing 330, a movement range of the sonic vibration module 300, which moves in a state in which contact between the head 320 and the body of the user is maintained, may be excessively limited, and vibrations may not be sufficiently transmitted to the body of the user. In addition, when the head 320 is excessively exposed from the housing 330, the head 320 may be excessively inclined by an external force applied from the side surface of the head 320, which may cause damage to the sonic vibration module 300.
Referring to
For example, when the maximum amplitude A of the vibration output from the sonic vibration module 300 is 3 mm and the exposure length l of the head 320 is 2 mm, a vertical movement range of the head 320 may be in a range of −1 mm to 5 mm with respect to a reference line. Here, when an external force is applied to the sonic vibration module 300 due to a tapping massage being performed using the sonic vibration module 300, even when the head 320 is pressed by 2 mm by pressure applied thereto, the head 320 may vibrate between 0 mm and −1 mm with respect to the reference line, and thus vibration having an amplitude of at least 1 mm may be transmitted to the body 5 of the user.
Therefore, while the sonic vibration module 300 moves in a preset rotation angle range, the human body stimulation unit 10 may be designed such that the exposed portion of the head 320 is formed such that the head 320 may come into contact the body 5 of the user even at any position.
Referring to
For example, when a maximum rotation angle at which the sonic vibration module 300 moves during a kneading operation is 45°, the exposed portion of the head 320 may have a solid angle of 80° that is greater than 45°. Here, as the solid angle of the exposed portion of the head 320 increases, a contact area with the body 5 may increase when the sonic vibration module 300 is inclined at the maximum rotation angle αmax. However, the head 320 may be tilted by an external force due to contact with the body 5, and thus a risk of damage to the sonic vibration module 300 may be further increased.
According to one embodiment, the exposed portion of the head 320 may be formed in consideration of a position of the head 320 which vertically moves due to sonic vibration. For example, while sonic vibration is generated, the solid angle β may be changed between a minimum solid angle and a maximum solid angle, and the minimum solid angle may be set to be greater than the maximum rotation angle αmax such that the head 320 is in continuous contact with the body of the user while the sonic vibration is generated.
Referring to
In
According to one embodiment, the head 320 of the sonic vibration module 300 may be exposed by a length that is less than a maximum amplitude of vibration output from the sonic vibration module 300 and may be designed to be exposed such that the solid angle of the head 320 is greater than the maximum rotation angle at which the sonic vibration module 300 moves. Thus, when a tapping massage is provided using the sonic vibration module 300, it is possible to prevent excessive damage to the sonic vibration module 300, and when a kneading massage is provided, it is possible to prevent a decrease in efficiency in which the sonic vibration module 300 applies sonic vibration to the body 5.
Therefore, it is possible to increase a life time of the human body stimulation device 1 by preventing the sonic vibration module 300 from performing an idle operation, also reduce noise generation, and continuously provide a vibration massage to the body 5.
The formation of the exposed portion of the head 320 is not limited to the above description, and the exposed portion of the head 320 may be implemented differently such as being formed in consideration of the shape, size, and length of the housing, and the shape, size, and length of the head.
The description above is merely illustrating the technical spirit of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments of the present specification described above may be implemented separately or in combination with each other.
Therefore, the embodiments disclosed in the present specification do not limit but describe the technical idea of the present invention, and the scope of the technical idea of the present invention is not limited by the embodiments. The scope of the present invention shall be interpreted on the basis of the accompanying claims, and it should be interpreted that all of the technical ideas included within the scope equivalent to the claims belong to the scope of the present invention.
