Description

Device and method for preventing, alleviating or treating degenerative brain diseases by inducing brainwave synchronization through tactile stimulation by acoustic vibration and music by bone conduction

[0001] The present invention relates to a device and method for preventing, alleviating or treating degenerative brain diseases by inducing brainwave synchronization through tactile stimulation by acoustic vibration and music by bone conduction.

[0002] Specifically, the present invention relates to a device and method thereof that are worn on the head of a wearer and stimulate the brain by providing acoustic vibration (vibro-acousticis) consisting of low-frequency (30 Hz to 120 Hz) vibrations and sounds that pass through the wearer's skull, thereby normalizing cerebral gamma oscillations due to increased cerebral blood flow, thereby preventing, alleviating, or treating degenerative brain diseases (e.g., mild cognitive impairment or early Alzheimer's disease (dementia)).

[0003] The human body naturally ages over time, resulting in natural pain and limited activity due to partial degeneration. Furthermore, industrial and technological advancements have led to restrictions on activity, traffic accidents, industrial accidents, sports injuries, and simple accidents related to physical activity. Furthermore, various complications stemming from stress, lack of exercise, and obesity have led to various diseases such as brain damage, myocardial infarction, arteriosclerosis, and arthritis.

[0004] To treat pain, injury, and obesity, which are natural human phenomena or sociocultural issues, various stimulating devices are being developed and utilized, including medications, health functional foods, and massage devices.

[0005] In general, massage devices are devices that stimulate the skin or scalp by tapping or rubbing them to promote smooth blood circulation, promote fat breakdown, and expel waste products. These massage devices generate vibrations or electrical stimulation using electrical signals and apply them to the skin or scalp. For example, massage devices include low-frequency massage devices that massage the body by applying low-frequency currents to the body through electrodes attached to the surface of the skin; ultrasonic massage devices that contact the surface of the skin with an ultrasonic probe to transmit ultrasonic vibrations to the body; and massage devices that utilize ultrasonic waves, far-infrared rays, etc.

[0006] However, among the human body vibration stimulation technologies currently being used, there are countless technologies being applied and utilized, such as linear stimulation using simple rotary vibration motors and solenoids, a pressurization method using air pressure, a stimulator that induces muscle contraction by inputting low-frequency current, and a method of contracting muscles using magnetic fields, but they are limited to simply applying pressure or stimulation to the human body, and each technology has limitations.

[0007] For example, in the case of a vibrator using a motor, the frequency can be adjusted, but the amplitude or intensity cannot be adjusted, which can cause damage to the human body due to incorrect use, and the vibration frequency also has a structure and characteristics that do not allow it to be transmitted rhythmically.

[0008] Recently, stimulation methods that utilize the principle of speakers have been provided to supplement this, but they do not provide enough intensity to allow for a smooth experience and simply serve as a speaker's subwoofer.

[0009] In addition, technologies utilizing low-frequency current, ultrasonic waves, and high-frequency waves are being disclosed and applied, but low-frequency waves cause a lot of inconvenience to users, and ultrasonic waves are difficult to immediately adapt to the user's feeling and effect, and there are fatal difficulties in use because the affected area is exposed and a medium is needed to transmit low-frequency waves or ultrasonic waves.

[0010] High-frequency devices, which are intended for deep heating rather than stimulation, pose inherent risks to users due to their inherent characteristics, as well as potential user anxiety. High-frequency devices require exposure of the affected area and a medium for transmission, and they utilize a conductive plate to transmit the electricity to the positive pole, which can be both dangerous and inconvenient.

[0011] Low-frequency treatment devices repeatedly apply low-frequency current in the form of low-frequency pulses to the skin through electrodes, which gives a feeling of electric shock and makes the treatment unpleasant, which reduces the effectiveness of the treatment. In addition, low-frequency treatment devices have the problem of women avoiding the treatment because the affected area must be exposed in order to attach the electrodes to the skin.

[0012] In addition, the ultrasonic treatment and beauty device transmits ultrasonic vibrations when the skin contact surface of the ultrasonic irradiation probe touches the skin, but if the probe is placed on the skin incorrectly, the ultrasonic vibrations are not transmitted, making it difficult to obtain sufficient effects. In addition, since the ultrasonic waves are irradiated at the output value set by the user regardless of whether the probe is in contact with the skin or not, when not in contact, the vibration transmitting part of the probe generates heat due to the vibration, causing the temperature of this part to rise, causing discomfort to the user, and there were various problems such as a risk of burns when used for a long time.

[0013] In addition, various skin care modes can be implemented using a vibrator that vibrates up and down by a magnetic coil method, and various technologies that enable galvanic massage and iontophoresis massage using the vibrator have been disclosed.

[0014] However, since these conventional technologies apply a method of stimulating the skin by converting the rotational power of the vibration motor into linear motion or cam motion, there is a problem that a lot of noise is generated during the process of transmitting the power of the vibration motor, which causes discomfort to users of the beauty device, and since it is a principle of causing vibration by eccentricity, there is a problem that the force distributed in the horizontal direction, that is, in the direction parallel to the skin surface, is large and the force acting perpendicular to the skin surface is small, making it difficult to effectively perform skin massage.

[0015] In addition, devices that generate sound waves and devices that can generate sound sources by applying the principle of speakers have been developed, but they have the problem that the frequency generation range is small and the intensity is also very weak due to problems such as the structural characteristics of the magnetic circuit, the position of the plate spring and the coil. In addition, there is a limit to miniaturization because a guide using a bearing to maintain the sound wave vibration in a vertical form and a coil spring to maintain elasticity must be configured.

[0016] These conventional technologies have very limited usage modes and functions, which limits their ability to effectively manage the human body.

[0017] The purpose of the present invention is to provide a device and method for preventing, alleviating or treating a degenerative brain disease (e.g., mild cognitive impairment or early Alzheimer's disease (dementia)) by normalizing cerebral gamma oscillations due to increased cerebral blood flow by stimulating the brain by providing acoustic vibration (vibro-acousticis) consisting of 40 Hz vibration and sound to the frontal lobe and temporal lobe of the wearer by being worn on the head of the wearer.

[0018] In order to achieve the above-described purpose, the present invention provides a device for preventing, alleviating or treating degenerative brain diseases by inducing brainwave synchronization through tactile stimulation by acoustic vibration and music by bone conduction, and a method thereof, wherein the device is worn on the head of a wearer and induces brainwave synchronization through tactile stimulation by acoustic vibration and music by bone conduction, wherein the device is characterized in that it has contact portions in two directions corresponding to the temporal lobe of the wearer and one direction corresponding to the frontal lobe of the wearer, thereby providing acoustic vibration to the temporal lobe and frontal lobe of the wearer.

[0019] According to the present invention, a device and method for preventing, alleviating or treating degenerative brain diseases by inducing brainwave synchronization through tactile stimulation by acoustic vibration and music by bone conduction, the device is worn on the head of the wearer and stimulates the brain by providing acoustic vibration (vibro-acousticis) consisting of 40 Hz vibration and sound to the frontal lobe and temporal lobe of the wearer, thereby normalizing cerebral gamma vibration due to increased cerebral blood flow, thereby having the effect of preventing, alleviating or treating degenerative brain diseases (e.g., mild cognitive impairment or early Alzheimer's disease (dementia)).

[0026] Terms or words used in this specification and claims should not be interpreted as limited to their usual or dictionary meanings, but should be interpreted as meanings and concepts that conform to the technical idea of ​​the present invention, based on the principle that the inventor can appropriately define the concept of the term to best explain his or her own invention.

[0027]

[0028] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. Therefore, it should be understood that there may be various equivalents and modified examples that can replace them at the time of filing this application.

[0029]

[0030] Hereinafter, before explaining with reference to the drawings, it is to be noted that matters that are not necessary to reveal the gist of the present invention, that is, known configurations that can be obviously added by a person skilled in the art with ordinary knowledge, are not illustrated or specifically described.

[0031]

[0032] The present invention relates to a device and method for preventing, alleviating or treating degenerative brain diseases by inducing brainwave synchronization through tactile stimulation by acoustic vibration and music by bone conduction.

[0033] Specifically, the present invention relates to a device and method thereof that are worn on the head of a wearer and stimulate the brain by providing acoustic vibration (vibro-acousticis) consisting of low-frequency (30 Hz to 120 Hz) vibrations and sounds that pass through the wearer's skull, thereby normalizing cerebral gamma oscillations due to increased cerebral blood flow, thereby preventing, alleviating, or treating degenerative brain diseases (e.g., mild cognitive impairment or early Alzheimer's disease (dementia)).

[0034]

[0035] Figures 1 to 3 each illustrate a vibration device used in a device for preventing, alleviating, or treating degenerative brain diseases by inducing brainwave synchronization through tactile stimulation by acoustic vibration and music by bone conduction according to the present invention from multiple directions.

[0036]

[0037] The device for preventing, alleviating or treating degenerative brain diseases by inducing brainwave synchronization through tactile stimulation by acoustic vibration and music by bone conduction according to the present invention according to the attached drawings is in the shape of a ring that can be wrapped around the wearer's head, with one side cut off to make it convenient to wear, and also provides elasticity to the ring shape to improve the wearing comfort.

[0038] In addition, the device according to the present invention is capable of providing acoustic vibration in a total of three directions. In other words, since it has a ring shape, each end is positioned on the temporal lobe of the wearer, and one end is positioned on the frontal lobe of the wearer, thereby providing a total of three contact points.

[0039] The above contact portion is configured in the form of a cover made of a flexible material on the surface, and a vibration device (100) is combined inside it to generate acoustic vibration.

[0040] The above vibration device (100) is as described below.

[0041]

[0042] In addition, a battery for power supply may be provided inside the contact portion along with a vibration device (100), and an operation interface including a power button for turning the device on / off and a button for adjusting the intensity of sound vibration may be provided on one side of the outer surface of the device.

[0043] Additionally, the other side of the device may be provided with a charging jack that charges the device with the power required to supply the battery, and a display that indicates the operating status of the device.

[0044]

[0045] A device configured in this manner may store sound sources by providing a separate database, but in some embodiments, may also receive sound source information by communicating with a terminal.

[0046]

[0047] Below, vibroacoustic stimulation is explained in more detail.

[0048] It is to provide acoustic vibration by combining 40Hz vibration and music to induce synchronization of gamma waves, and it has a wavelength when 40Hz is combined with music (sound source) as shown in [Table 1].

[0049]

[0050]

[0051] When these acoustic vibrations are provided to the sense of touch through vibration, the amount of cerebral blood flow (CBF) increases, and oxyhemoglobin (HbO2) increases, activating nerve cells.

[0052] When acoustic vibrations are provided to the auditory sense through a sound source, the auditory cortex and amygdala are stimulated, leading to recall of past memories. Since all of these are provided through tactile and auditory senses, memory and cognitive ability can be improved as shown in [Table 2], and thus, prevention, alleviation, or treatment of degenerative brain diseases (e.g., mild cognitive impairment or early Alzheimer's disease (dementia)) can be achieved.

[0053]

[0054]

[0055]

[0056] The stimulation methods conventionally used for the treatment of brain diseases include deep brain stimulation (DBS), transcranial alternating current / direct current stimulation (tACS, tDCS), transcranial magnetic stimulation (TMS), and ultrasound stimulation (Ultrasound), as shown in [Table 3].

[0057]

[0058]

[0059]

[0060] That is, in the case of deep brain stimulation (DBS), in addition to the risk of needle insertion, there is a very high risk of bleeding and infection during surgery, and in the case of transcranial alternating current / direct current stimulation (tACS, tDCS), there is a risk of scalp damage at the electrode site and even burns.

[0061] Additionally, in the case of transcranial magnetic stimulation (TMS), there is a risk of side effects such as visual and auditory hallucinations, and in the case of ultrasound stimulation (Ultrasound), there is a risk of skin and tissue necrosis with long-term use.

[0062] On the other hand, since the acoustic vibration stimulation according to the present invention only uses 40 Hz, which is the vibration and frequency that is exposed in daily life, the possibility of side effects can be considered very low.

[0063]

[0064] The device according to the present invention has a ring portion at each end of the device, as shown in Fig. 3 of the attached drawing, and a fitting module is coupled through the ring portion.

[0065] The above fitting module is extended by combining a support plate having a predetermined degree of flexibility, and since there are two fitting modules combined with the ring portion provided at each end, the support plate is also composed of two.

[0066] At this time, one of the support plates is provided with a plurality of arranged holes, and the other is provided with a protrusion, so that when two support plates are adjacent to each other, the protrusion provided on one is fitted into the hole provided on the other, thereby allowing the two support plates to be combined.

[0067] Additionally, to maintain bonding strength, the two support plates are stably bonded using a band.

[0068]

[0069] In addition, the support plate integrally extended from the above-mentioned fitting module has a predetermined angle, and by allowing the support plate to be positioned on the scalp of the wearer's head due to this angle, more stable wearing of the device can be achieved.

[0070] Additionally, by being connected to the ring portion through the fitting module, the device can be worn without the support plate when the fitting module is detached from the ring portion.

[0071]

[0072] Below, the vibration device (100) is described in detail.

[0073] The vibration device (100) according to the present invention is described with reference to FIG. 4 and below of the attached drawings.

[0074] Referring to FIGS. 4 and 5, the vibration device (100) of the present invention includes upper and lower bodies (110, 180), upper and lower brackets (120, 160), a magnetic body (130), a voice coil (132), an upper plate (134), a bobbin (140), a cone damper (150), and a connecting member (170). In addition, although not shown in the drawings, the vibration device (100) may further be provided with a waterproofing member or a buffering member.

[0075] In this embodiment, the configuration of a vibration device is described in detail using a connecting member (170) for transmitting vibrations generated from a vibration device (100) to the outside so as to massage and stimulate the skin or scalp of a human body, and a vibration probe (190) coupled to the connecting member (170) to massage and stimulate the human body.

[0076] That is, the vibration probe (190) is detachably provided on the vibration device (100).

[0077] These vibration probes (190) can have various shapes and sizes to suit various uses of the human body stimulation device (200 in FIG. 4) described below.

[0078] The vibration probe (190) of this embodiment includes a plate (192) on which a massage or stimulation head (not shown) is mounted and detached, a shaft (194) coupled to the center of the lower surface of the plate (192), and a coupling portion (196) provided at the lower end of the shaft (194) and mutually coupled with a coupling member (170). Here, the coupling portion (196) is provided in the form of a bolt that is screw-coupled with the coupling member (170).

[0079]

[0080] Meanwhile, the vibration probe (190) described above has a concave groove (1) formed upward on one side of the shaft (194) where the bolt (176) is not formed, and a vibrating body (2) is connected to the groove (1) by a connecting body (4).

[0081] At this time, the connector (4) has a two-stage 'convex' shape, and a part of the connector (4) is inserted into and fixed into the insertion groove (3) formed in the vibrating body (2).

[0082] The size of the above insertion groove (3) is larger than the size of a part inserted into the insertion groove of the connector (4).

[0083] This is illustrated in Fig. 5a.

[0084] Figure 5a shows another example of a vibration device.

[0085]

[0086] In addition, the vibrating body (2) has a smaller size than the groove (1), thereby enabling it to swing about the connecting body (4) within the groove (1).

[0087]

[0088] At this time, an elastic body (5) is provided between one side of the home portion (1) and the upper surface of the vibrating body (2). The elastic body (5) described above can be referred to in Fig. 5b of the attached drawing.

[0089] Figure 5b is an enlarged view of the elastic body of Figure 5a.

[0090]

[0091] An elastic body (5) according to Fig. 5b of the attached drawing has a first shaft (51) having a cylindrical shape with a hollow interior and a first wing (52) and a second wing (53) extending symmetrically on both sides, and having two guide grooves (54) formed along the longitudinal direction on one side and formed so that one end is open;

[0092] A second shaft (55) having a cylindrical shape and having a third wing (56) and a fourth wing (57) symmetrically extended on both sides;

[0093] The third wing (56) and the fourth wing (57) each include an insertion groove (56a, 57a) formed to have a predetermined length adjacent to the second axis (55).

[0094]

[0095] That is, the second shaft (55) is inserted into the hollow of the first shaft (51) as the third wing (56) and the fourth wing (57) are inserted into each of the guide grooves (54) of the first shaft (51) and guided.

[0096] In addition, a torsion spring is inserted through the insertion groove (56a, 57a) as shown in Fig. 2b, and at this time, one protruding end of the torsion spring is fixed in close contact with one surface of the third wing (56), and the other protruding end in the other direction is fixed in close contact with one surface of the second wing (53).

[0097]

[0098] Accordingly, the elastic body (50) can be folded and driven within a range in which the third wing (56) and the fourth wing (57) can move from the guide groove (54) while having an 'X' shape due to the elastic force of the torsion spring.

[0099]

[0100] By having this configuration, the shaft (194) of the vibration probe (190) according to the present invention has the effect of increasing the intensity of vibration assisted by the vibrating body (2), and also reducing the impact due to vibration applied to the probe itself even when the intensity of vibration increases by the elastic body (5).

[0101]

[0102] At this time, the vibrating body (2) includes a sloped surface inclined in a predetermined direction on the lower surface as shown in Fig. 2a of the attached drawing, so that the vibrating body (2) can vibrate without being affected by the upper surface of the connecting member (170) corresponding to the lower surface of the groove (1). An example of this lower surface may have a wedge or cone shape, unlike the attached drawing.

[0103]

[0104] Specifically, the lower body (110) is provided in a cylindrical shape with an open upper portion and forms a space in which a magnetic body (130) is installed inside. The magnetic body (130) is fixedly installed on the bottom surface of the internal space of the lower body (110). In addition, the lower bracket (120) is inserted and installed on the outside of the magnetic body (130) of the internal space of the lower body (110). To this end, the lower body (110) is provided with a fixing groove (112) formed on the bottom surface in which the magnetic body (130) is fixedly installed, a ring-shaped spacing groove (114) provided so as to be spaced apart from the outer surface of the magnetic body (130) fixed to the fixing groove (112) at a predetermined distance, and a ring-shaped mounting groove (116) in which the lower bracket (120) is mounted so as to be spaced apart from the magnetic body (130) at a predetermined distance. The separation groove (114) is provided to form a magnetic path of a magnetic field formed by a magnetic body (130) and a voice coil (132).

[0105]

[0106] The upper body (180) is provided in a cylindrical shape with an open bottom and covers the open top of the lower body (110). The upper body (180) is coupled to the lower body (110) to form a space for accommodating parts (120 to 160) therein. The upper surface (182) of the upper body (180) has an insertion hole (184) in the center through which a connecting member (170) and a shaft (194) of a vibration probe (190) are inserted, and a plurality of heat dissipation holes (186) are formed on the outside of the insertion hole (184) to release heat generated when the vibration device (100) generates vibration. In addition, a waterproofing member (not shown), such as silicone, may be further provided on the upper surface (182) of the upper body (180) to waterproof the insertion hole (184) into which the vibration probe (190) is inserted. These upper body (180) and lower body (110) are made of aluminum to improve heat dissipation effect.

[0107]

[0108] The lower bracket (120) is provided in a cylindrical shape with the upper and lower parts open. The lower bracket (120) is installed in the mounting groove (116) of the lower body (110), and the upper surface is coupled with the cone damper (170). For this purpose, the lower bracket (120) is provided with a plurality of coupling protrusions (122) on the upper surface. A bobbin (140) having a voice coil (132) mounted thereon is installed on the inside of the lower bracket (120). A portion of the lower bracket (120) protrudes toward the upper part of the lower body (110). When the lower bracket (120) is coupled with the damper (158) of the cone damper (150), a silicone washer or the like may be further used to secure durability and maintain vibration force. This allows the use of a silicon washer to selectively adjust the height of the cone damper (150) according to frequency characteristics, thereby performing the function of maintaining efficient amplitude.

[0109]

[0110] The upper bracket (160) is provided in a plate shape and is accommodated inside the upper body (180), and its edge is coupled with the upper portion of the lower bracket (120). A plurality of coupling protrusions (162) are provided on the lower surface of the edge of the upper bracket (160) so that the cone damper (150) and the lower bracket (120) are coupled.

[0111] The upper surface of the upper bracket (160) is provided in a generally circular shape facing the lower bracket (120). The upper surface of the upper bracket (160) has an insertion hole (164) in the center through which a connecting member (170) is inserted, and a plurality of heat dissipation holes (166) are formed on the outer side of the insertion hole (164) to release heat generated when the vibration device (100) vibrates. The insertion holes (184, 164) of the upper body (180) and the upper bracket (160) fix the connecting member (170) and the vibration probe (190) to the central portion of the vibration device (100). In addition, a buffer member (not shown) such as a plate spring may be further provided between the upper surface of the upper bracket (160) and the upper body (180) to prevent unnecessary vibration transmission.

[0112]

[0113] The magnetic body (130) is fixedly installed in the fixed groove (112) of the lower body (110) and interacts with the voice coil (132) to generate a magnetic field. The magnetic body (130) is provided as a permanent magnet of a ferromagnetic body, such as a neodymium magnet, for example. An upper plate (134) is installed on the upper surface of the magnetic body (130).

[0114] The voice coil (132) is installed on the outer surface of the bobbin (140) above the magnetic body (130). The voice coil (132) is guided by the bobbin (140) to be stably installed. The voice coil (132) receives power and interacts with the magnetic body (130) to generate a magnetic field. The magnetic body (130) and the voice coil (132) are installed inside the lower bracket (120).

[0115] The upper plate (134) has a shape generally similar to the upper surface of the magnetic body (130), is provided on the upper surface of the magnetic body (130), and is installed adjacent to the lower surface of the bobbin (140). The upper plate (134) guides the magnetic force of the magnetic body (130) to be concentrated on the voice coil (132) in order to prevent loss of the magnetic field generated by the magnetic body (130). The upper plate (134) may have a magnetic fluid (not shown) applied to the outer diameter to form a magnetic field.

[0116]

[0117] The bobbin (140) is made of a non-magnetic material, such as aluminum. The bobbin (140) is installed on the inside of the lower bracket (120). The bobbin (140) guides the voice coil (132) to be stably installed on the outside, thereby preventing the voice coil (132) from coming off. The bobbin (140) is connected to the connecting member (170) at the center of the upper surface. To this end, the bobbin (140) is provided in a cylindrical shape with open upper and lower sides, and has a lower surface (148) whose upper surface (142) is larger than the radius of the side surface, and whose lower side extends outward to face the upper surface (142). The voice coil (132) is installed on the side surface of the bobbin (140). At this time, the voice coil (132) is guided by the upper surface (142) and the lower surface (148) of the bobbin (140).

[0118] And, on the upper surface (142) of the bobbin (140), a connecting hole (144) is formed in the center to be connected to the lower end of the connecting member (170), and a plurality of heat dissipation holes (146) are formed on the outside of the connecting hole (144) to release heat generated when the vibration device (100) vibrates. These heat dissipation holes (146) have a heat dissipation effect and a function of reducing noise when vibration occurs. In addition, the bobbin (140) releases heat generated from the voice coil (132).

[0119] This bobbin (140) has a magnetic body (130) fixed to the fixing groove (112) of the lower body (110) and is located on the inner diameter of the lower surface (148) of the bobbin (140), thereby creating an efficient magnetic field, and when the voice coil (132) wound around the bobbin (140) is magnetized, mutual attractive and repulsive forces are generated, thereby generating a stable vibration force. In addition, since the bobbin (140) is coupled to the vibration probe (190) through the connecting member (170), even if physical eccentricity occurs when the vibration probe (190) is stimulated by the human body, the strong magnetic field generated by the coupling of the magnetic body (130) and the upper plate (134) serves to correct the eccentricity in the bobbin (140).

[0120]

[0121] The cone damper (150) is installed on the upper surface (142) of the bobbin (140) and generates vibration in the vertical direction by using the magnetic field generated by the interaction between the magnetic body (130) and the voice coil (132). That is, the cone damper (150) generates vibration by acting as a speaker to generate sound of the sound source by causing the vibration of the sound source to act as vibration of the air. The cone damper (150) is coupled to the upper and lower brackets (120, 160) at the edges. For this purpose, the cone damper (150) is provided with a cone plate (152) and a plurality of dampers (158).

[0122] The cone plate (152) has a connecting hole (154) formed in the center to be connected to the lower end of the connecting member (170), and a plurality of heat dissipation holes (156) are formed on the outside of the connecting hole (154). Each of the dampers (158) is provided in a shape that extends radially in a curved band shape from the cone plate (152) in order to maximize the vibration force of the cone damper (150), and a connecting hole (159) for screw connection is formed at the end. The dampers (158) are fixed by screw connection between the connecting protrusions (162) of the upper bracket (160) and the connecting protrusions (122) of the lower bracket (120) through the connecting holes (159).

[0123] In addition, in order to ensure durability, the cone damper (150) is supported by using elastic members such as silicone washers at the upper and lower portions of the coupling hole (159) of the damper (158), thereby preventing vibration from being attenuated when vibration occurs and generating soft sound.

[0124] Therefore, the cone damper (150) generates vibration in response to changes in acoustic pressure of a sound source supplied from the outside. The cone damper (150) is coupled to a connecting member (170) at the center, and transmits vibration to an external source, for example, a vibration probe (190), through the connecting member (170). Since the amplitude of vibration is the largest at the center of the cone damper (150), the vibration transmission efficiency can be improved by coupling the bolt (176) of the connecting member (170) and the coupling hole (154) of the cone damper (150). In this embodiment, the vibration device (100) is coupled to the center of the upper surface (142) of the cone damper (150) and the bobbin (140) so as to improve the coupling force with the connecting member (170).

[0125]

[0126] And the connecting member (170) directly receives the vibration generated from the cone damper (150) and transmits the vibration to the outside. In this embodiment, the connecting member (170) is coupled with the shaft (194) of the vibration probe (190). That is, the connecting member (170) is provided in an axial shape, and the upper part is coupled with the shaft (194) of the vibration probe (190), and the lower part is coupled to the cone damper (150) and the upper surface (142) of the bobbin (140).

[0127] To this end, the connecting member (170) has a shaft-shaped body (172), a coupling groove (174) in which a shaft (194) is coupled to the upper portion of the body (172), and a coupling bolt (176) coupled to the coupling hole (154) of the cone damper (150) and the coupling hole (144) of the bobbin (140) in the lower portion of the body (172). In this embodiment, the coupling hole (174) has a structure in which the coupling portion (196) of the shaft (194) is screw-coupled.

[0128]

[0129] *

[0130] Therefore, in the vibration device (100) of the present invention, the shaft (194) of the vibration probe (190) is inserted and penetrated through the center of the upper body (180) to be coupled with the connecting member (170), and the connecting member (170) is inserted and penetrated through the upper bracket (160) to be screw-coupled to the center of the cone damper (150) and the bobbin (140). Therefore, when the cone damper (150) generates vibration in the vertical direction due to acoustic pressure in the vibration device (100), the vibration is transmitted to the vibration probe (190) through the connecting member (170) coupled to the cone damper (170).

[0131]

[0132] Another embodiment of the connecting member (170) is illustrated in FIG. 6.

[0133] Referring to FIGS. 6A and 6B, in this embodiment, the vibration probe (190a) has a fixing groove (198) formed at a specific position along the outer surface of the shaft (194a). The fixing groove (198) is formed, for example, on the outer surface of the portion where the shaft (194a) of the vibration probe (190a) is inserted into the joining groove (174) of the connecting member (170a). The fixing groove (125) has a catch formed at the upper portion and a guide formed at the lower portion.

[0134] And, an elastic fixing pin (178) that is inserted into a fixing groove (198) is fixedly mounted on the connecting member (170a). The elastic fixing pin (178) is fixedly connected to the outside of the connecting member (170a), and a part of it is exposed inside the connecting groove (174) of the connecting member (170a), and the exposed part is seated in or separated from the fixing groove (198) of the shaft (194a).

[0135] When the shaft (194a) of the vibration probe (190a) is pressed downward and inserted into the coupling groove (174), the elastic fixing pin (178) is guided to be seated in the fixing groove (198) by the guide portion of the fixing groove (198), and at the same time, the elastic fixing pin (178) is fixedly mounted by the catch. In addition, when the shaft (194a) of the connecting member (170a) is pressed upward and separated from the coupling groove (174), the elastic fixing pin (178) is easily detached from the fixing groove (178) by the guide portion of the fixing groove (198).

[0136]

[0137] In this embodiment, the vibration probe (190a) can be easily coupled and separated from the connecting member (170) than the screw coupling structure of FIGS. 4 and 5, and damage to the coupling portion (196) of the vibration probe (190) that may occur when the vibration probe (190a) is coupled and separated from the vibration device (100) multiple times can be prevented.

[0138] Therefore, the vibration probe (190, 190a) of the present invention uses a connecting member (170, 170a) that is connected using a screw connection or a fixing groove (198) and an elastic fixing pin (178), so that assembly is easy during manufacturing.

[0139] As described above, the vibration device (100) of the present invention directly receives vibration from the central portion of the cone damper (150) by coupling the connecting member (170, 170a) and the shaft (194, 194a) of the vibration probe (190, 190a) to the central portion of the cone damper (150) that generates vibration in response to changes in the acoustic pressure of the sound source. In addition, the vibration device (100) of the present invention couples the connecting member (170) and the shaft (194, 194a) of the vibration probe (190, 190a) together with the cone damper (150) to the central portion of the upper surface (142) of the bobbin (140), thereby improving the coupling force with the connecting member, and thereby improving the vibration transmission efficiency.

[0140] In addition, the vibration device (100) of the present invention can improve the efficiency of vibration generation by configuring a cone damper (150) in the shape of a plate spring with a cone plate (152) that generates sound waves and a damper (158) that transmits vibration force and has a spring function, in order to generate stable vibration.

[0141] In addition, the vibration device (100) of the present invention is described as having a structure having upper and lower bodies (110, 180) and upper and lower brackets (120, 160), but in order to further simplify the structure and improve the vibration generation efficiency and heat dissipation effect, it can be implemented as a structure without the upper body (180) and the upper bracket (160). This is because the connection member (170) is coupled to the cone damper (150) and the upper surface (142) of the bobbin (140), so that the coupling with the vibration probe (190) is firm.

[0142]

[0143] The description using the drawings above only describes the main aspects of the present invention, and it is obvious that the present invention is not limited to the configuration of the drawings, as various designs are possible within the technical scope.
