Description

[Technical Field]

[0001] The present invention relates to an electric stimulation bone conduction headset, and more particularly to an electric stimulation bone conduction headset that includes both a bone conduction unit and an electric stimulation unit and is highly effective not only in preventing hearing loss through bone conduction but also in treating tinnitus. [Background technology]

[0002] Generally, sounds heard by the human ear are transmitted in the form of waves. External sounds enter the human outer ear and vibrate the eardrum, stimulating cells in the inner ear behind the eardrum and transmitting the sound to the brain.

[0003] The frequency range of sounds that humans can hear is approximately 20-20,000 Hz, and the frequency range of sounds that humans communicate with is approximately 500-2,000 Hz.

[0004] However, a person with hearing loss may not be able to hear all or some of the frequencies within the range of sound frequencies.

[0005] Therefore, bone conduction, which transmits sound through vibrations in the skull, is now widely used.

[0006] The bone conduction method transmits sound by vibrating the skull to the cochlea, then to the brain via the auditory nerve. This method omits the process in which vibrations pass through the eardrum and the three bones located within it in the voice recognition mechanism.

[0007] In other words, bone conduction headsets transmit acoustic vibrations applied to the skin surface around the ear directly to the cochlea through the skull, so that even hearing-impaired people with abnormalities in the eardrum or ossicles can reliably hear sound through bone conduction through the skin and bones, as long as their cochlea and auditory nerves are normal.

[0008] On the other hand, in the case of air conduction headsets, the risk of safety accidents increases because the ears are covered and surrounding sounds cannot be heard.

[0009] In contrast, developed countries have legal restrictions on wearing air-conduction earphones or headphones that cover the ears, preventing people from listening to music and other media on the road.

[0010] Furthermore, with the remarkable spread of digital audio and communication devices in recent years, noise-induced hearing loss has increased among young people worldwide, with more than 10% of the population reporting hearing loss. In an age of aging worldwide, the increase in age-related hearing loss is also seen as a social issue, and alternatives being proposed include reducing the volume of speakers that receive signals via air conduction and reducing the amount of time they are used.

[0011] On the other hand, when using a bone conduction headset, you keep your ears open, so you can receive surrounding sounds at the same time, preventing safety accidents. It also prevents hearing loss by not directly affecting the eardrum.

[0012] Such bone conduction headsets transmit sound by vibrating the bones around the ears, making them useful not only for the hearing impaired but also for people who work in noisy environments.

[0013] Meanwhile, Transcutaneous Electrical Nerve Stimulation (TENS) is a method of treating various pains caused by various causes by stimulating peripheral sensory nerves in the skin using electric current of a specific frequency and intensity, and is applied to various parts of the body.

[0014] Specifically, transcutaneous electrical nerve stimulation uses a low-voltage modified steady-state current or low-frequency current, and the pulsation frequency, pulsation amplitude, and stimulation intensity can be set in a variety of ways depending on the body part to which it is applied and the physical characteristics of each individual.

[0015] There are various parameters for transcutaneous electrical nerve stimulation (TES), but important considerations for TES treatment include current pulsation frequency, pulsation amplitude, stimulation intensity and treatment time, stimulation site, and electrode placement method.

[0016] For example, waveforms such as monophasic rectangular waves, asymmetrical biphasic rectangular waves, symmetrical biphasic rectangular waves, modified spike waves, monophasic rectangular high frequency carriers or sine waves are frequently used.

[0017] The pulse rate is diverse within a range such as 10 - 100 pps, 20 - 200 pps, etc., and usually ranges from 1 - 100 pps. An appropriate pulse rate can be selected and adjusted for use.

[0018] The pulse duration is diverse within a range such as 10 - 200 μs, 120 - 330 μs, 50 - 500 μs, etc., with a range of 10 - 600 μs. Asymmetrical biphasic rectangular waves have a pulse width of 50 - 500 μs, and monophasic rectangular waves have a pulse width of 10 - 100 μs.

[0019] The intensity of the stimulus is diverse, such as 10 - 50 mA, 100 mA or less, 150 mA or less, etc., but usually it is often up to 100 mA.

[0020] Also, electrodes vary in size and shape, and depending on the material, there are pad electrodes, carbon silicon electrodes, disposable paper electrodes, Karaya gum electrodes, etc., and carbon silicon electrodes are frequently used.

[0021] The shape and size of the electrodes are also very diverse, such as circular snaps with a diameter of 5 cm, pin types, squares, rectangles, banana types, etc., so electrodes suitable for the characteristics of the treatment site can be selected and used.

[0022] The above-mentioned transcutaneous electrical nerve stimulation is known to be effective for tinnitus or hearing loss, and in recent years, treatments that involve stimulation around the ear have been used. [Prior art documents] [Patent documents]

[0042] A battery module is detachably coupled to the rear end of the ear hook, and a charging port is formed in the battery module.

[0043] A third sheet groove is formed in a portion of the surface of the battery module that contacts the mastoid process. [Effects of the Invention]

[0044] According to the present invention having the above-described configuration, the following effects can be obtained.

[0045] First, according to the present invention, the device is characterized by comprising a neckband portion that covers the back of the user's head in a band-like manner, ear hook portions that are placed on both ends of the neckband portion and hung over the user's ears, a bone conduction portion that is provided near the tip of each ear hook portion, an electrical stimulation portion that is provided spaced behind the bone conduction portion and has electrodes on the side that touches the skin, and a control portion that controls the operation of the bone conduction portion and the electrical stimulation portion.Therefore, by providing both the bone conduction portion and the electrical stimulation portion, there is an advantage that significant effects can be expected in the prevention and treatment of hearing loss and tinnitus.

[0046] In addition, according to the present invention, the electrical stimulation unit is connected to the rear end of the ear hook, and the electrical stimulation unit contacts the mastoid process to provide electrical stimulation, thereby making treatment of hearing loss or tinnitus more effective.

[0047] Furthermore, according to the present invention, the electrical stimulation unit is configured to be detachable from the ear hook unit, so that when the electrical stimulation unit is detached, it can only function as a bone conduction earphone, and if an abnormality occurs in the electrical stimulation unit, it can be separated and repaired or otherwise maintained.

[0048] In addition, according to the present invention, a connection hole is formed in the vertical direction at the lower end of the ear hook portion, and the electrical stimulation unit is connected by inserting it through the connection hole.The electrical stimulation unit includes a battery, and a filling port is provided for filling the battery.Therefore, the battery can be safely protected by being inserted into the ear hook portion through the connection hole, and the battery for operating the electrical stimulation unit can be filled separately, making filling easy.

[0049] In addition, according to the present invention, a sheet portion is formed around the electrode of the electrical stimulation unit, and a first sheet groove is formed between the electrode and the sheet portion, so that the sheet portion is seated opposite the mastoid process, thereby enabling electrical stimulation to be transmitted more effectively.

[0050] In addition, according to the present invention, a second sheet groove that seats on the mastoid process is formed in the ear hook portion to which the electrical stimulation unit is connected, so that even if the electrical stimulation unit separates from the ear hook portion, unstable contact with the mastoid process can be avoided.

[0051] In addition, according to the present invention, a locking hole is formed on the side of the ear hook portion to which the electrical stimulation unit is connected, and a locking protrusion that fits into the locking hole is formed on the electrical stimulation unit.Therefore, when the electrical stimulation unit is connected through the connection hole at the lower end of the ear hook portion, the locking hole and the locking protrusion catch on each other, resulting in a one-touch connection with a click, making it possible to easily connect the electrical stimulation unit.

[0052] In addition, according to the present invention, a switch connected to the control unit is located on the back of the ear hook to which the electrical stimulation unit is connected, so that parameters such as the stimulation intensity, frequency, and pulsation period of the electrical pulse can be set according to the application.

[0053] Furthermore, according to the present invention, the electrical stimulation unit is provided on a connecting frame that extends rearward from the bone conduction unit, which allows the electrodes to transmit electrical stimulation to the tragus nerve, thereby providing an effect on a variety of symptoms, including not only tinnitus but also hearing loss.

[0054] Furthermore, according to the present invention, the connecting frame is configured to be separable from the bone conduction section, so that when the electrical stimulation section is separated, not only can it function as a bone conduction earphone, but if an abnormality occurs in the electrical stimulation section, it can be separated and repaired or otherwise maintained.

[0055] In addition, according to the present invention, the bone conduction unit protrudes inward toward the user's head, and the connecting frame is formed with an assembly groove to which the bone conduction unit is coupled. The protruding portion of the bone conduction unit is coupled to the assembly groove, allowing the connecting frame to rotate freely around the bone conduction unit, making it easy to adjust to fit different bodies. Furthermore, the connecting frame has a communication hole that allows the user to hear external sounds through the ear canal, thereby avoiding the risk of safety accidents.

[0056] In addition, according to the present invention, the surface of the connecting frame on the opposite side of the bone conduction section and the tip of the bone conduction section are formed in a convex shape to complementarily correspond to the user's temple, allowing for closer contact with the skin, resulting in an excellent bone conduction acoustic transmission effect.

[0057] In addition, according to the present invention, a battery module is detachably connected to the rear end of the ear hook portion, and a charging port is formed in the battery module, making it easy to attach and detach the battery. Furthermore, since the relatively heavy battery is placed close to the center of gravity, stability is improved and the electrical stimulation bone conduction headset can be prevented from easily coming off the head.

DETAILED DESCRIPTION OF THE INVENTION

[0059] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0060] As shown in Figures 1 and 5, the electrical stimulation bone conduction headset 1000, 1000' according to the present invention comprises a neckband unit 100 that wraps around the back of the user's head in a belt-like manner, ear hook units 200 that are arranged on both ends of the neckband unit 100 and hung on the user's ears, bone conduction units 300 that are provided near the tips of each ear hook unit 200, an electrical stimulation unit 400 that is provided spaced rearward from the bone conduction unit 300 and has an electrode 450 on the side that touches the skin, and a control unit (not shown) that controls the operation of the bone conduction unit 300 and the electrical stimulation unit 400.

[0061] With this configuration, the electrical stimulation bone conduction headset 1000 of the present invention has the advantage of being able to effectively prevent hearing loss through bone conduction and treat tinnitus, hearing loss, or tinnitus through electrical stimulation by combining the bone conduction unit 300 and the electrical stimulation unit 400.

[0062] Hereinafter, two embodiments of the electrostimulation bone conduction headset 1000 will be described, but the present invention is not limited thereto, and various embodiments and modifications are possible within the scope of the claims described below.

[0063] Embodiment 1 As shown in FIGS. 1 to 4, the electrical stimulation unit 400 according to this embodiment is connected to the rear end of the ear hooking unit 200.

[0064] As a result, the electrical stimulation unit 400 contacts the mastoid process and electrically stimulates it, thereby enabling effective treatment of tinnitus, hearing loss, or tinnitus.

[0065] In particular, according to this embodiment, the electrical stimulation unit 400 is configured to be separable from the ear hook unit 200 .

[0066] Therefore, when the electrical stimulation unit 400 is separated, it can only function as a bone conduction earphone, and if an abnormality occurs in the electrical stimulation unit 400, it can be separated and repaired or maintained.

[0067] For example, as shown in the figure, a coupling hole 210 is formed in the upper and lower direction at the lower end of the ear hook part 200, and the electrical stimulation part 400 can be inserted through the coupling hole 210 and detachably coupled thereto.

[0068] The electrical stimulation unit 400 may include a built-in battery (not shown) and may be provided with a charging port 420 for charging the battery.

[0069] Therefore, the batteries for operating the electrical stimulation unit 400 can be charged separately, which allows for easy charging.

[0070] In this case, it is preferable that the battery of the electrical stimulation unit 400 is inserted into the coupling hole 210 so as not to be exposed.

[0071] The battery may be used to operate the bone conduction unit 300, but a separate battery for operating the bone conduction unit 300 may also be provided.

[0072] In this case, the separate battery may be built into the neckband unit 100 or the like.

[0073] A sheet portion 490 is formed around the electrode 450 of the electrical stimulation unit 400, and a first sheet groove 430 is formed between the sheet portion 490 and the electrode 450, so that the sheet portion 490 is seated facing the mastoid process, thereby preferably allowing the electrical stimulation to be transmitted more effectively.

[0074] The seat portion 490 may be a seat ring that protrudes in the direction of the electrode 450 along the periphery of the electrode 450 or a seat edge portion that has an inner wall surface along the periphery of the electrode 450 .

[0075] That is, the sheet portion 490 around the electrode 450 forming the first sheet groove 430 is made of rubber or silicone material, and is configured so that when the electrode 450 is in contact with the mastoid process, the sheet portion 490 around the electrode 450 flexibly fits securely on the inside of the lower end of the user's mastoid process.

[0076] The ear hook 200 connected to the electrical stimulation unit 400 contains electrodes 450 and leads connected to a control unit and a battery.

[0077] In addition, the ear hook part 200 to which the electrical stimulation part 400 is connected is formed with a second sheet groove 220 that seats on the mastoid process, so that even if the electrical stimulation part 400 separates from the ear hook part 200, unstable contact with the mastoid process can be avoided.

[0078] A locking hole 240 is formed on the side of the ear hook part 200 to which the electrical stimulation part 400 is connected, and the electrical stimulation part 400 may have a locking protrusion 440 that fits into the locking hole 240.

[0079] With this configuration, when the electrical stimulation unit 400 is connected through the connection hole 210 at the lower end of the ear hook 200, the locking hole 240 and the locking protrusion 440 are caught together, resulting in a one-touch connection with a click.

[0080] As shown in Figure 5, the locking holes 240 are formed in multiple numbers at intervals along the vertical direction, i.e., the longitudinal direction of the ear hook portion 200, and the locking protrusions 440 may also be formed in multiple numbers at intervals along the longitudinal direction of the electrical stimulation portion 400.

[0081] With this configuration, the insertion length of the electrical stimulation unit 400 through the coupling hole 210 can be adjusted, thereby making it possible to appropriately accommodate different body structures of different users.

[0082] That is, when the electrical stimulation unit 400 is inserted deepest through the connection hole 210 and the locking hole 240 and the locking protrusion 440 are connected, the electrode 450 is positioned at the top position, and when the electrical stimulation unit 400 is connected in the shallowest inserted state, the electrode 450 is positioned at the bottom position.

[0083] In this case, even if the insertion position of the electrical stimulation unit 400 is changed, it is of course possible for the electrical and / or communicative connection to the control unit and the switch to be possible.

[0084] A switch 470 connected to the control unit may be disposed on the rear surface of the ear hook 200 to which the electrical stimulation unit 400 is coupled.

[0085] In this case, the switches 470 may include switches for setting various parameters such as the stimulation intensity, frequency, and pulsation cycle of the electrical pulses for treating tinnitus.

[0086] The control unit, such as a printed circuit board, may be built into the earring 200 in which the electrical stimulation unit 400 is provided, or may be located inside a case that houses the bone conduction unit 300.

[0087] Embodiment 2 As shown in FIGS. 5 to 8, in describing the electrical stimulation bone conduction headset 1000' of the second embodiment, the same components as those of the first embodiment are denoted by the same reference numerals, and additional description will be omitted.

[0088] First, according to this embodiment, the electrical stimulation unit 400 is provided on a connecting frame 800 that extends rearward from the bone conduction unit 300.

[0089] That is, the connection frame 800 extends rearward with the bone conduction unit 300 at the center, and the electrical stimulation unit 400 including the electrode 450 is provided at a position separated from the bone conduction unit 300 .

[0090] The connection frame 800 contains electrodes 450 and leads connected to a control unit and a battery.

[0091] The electrode 450 preferably contacts the tragus nerve region of the user to deliver electrical stimulation, but does not necessarily need to be attached to that region.

[0092] Through electrical stimulation, it can be effective in treating a variety of symptoms, including tinnitus, hearing loss, and pain relief.

[0093] Furthermore, the connection frame 800 may be configured to be separable from the bone conduction unit 300 .

[0094] As a result, when the electrical stimulation unit 400 is separated, it can only function as a bone conduction earphone, and if an abnormality occurs in the electrical stimulation unit 400, it can be separated and repaired or maintained separately.

[0095] The bone conduction unit 300 protrudes inward toward the user's head, and the connecting frame 800 is formed with an assembly groove 810 to which the bone conduction unit 300 is coupled. The protruding portion of the bone conduction unit 300 is coupled to the assembly groove 810, allowing the connecting frame 800 to rotate freely around the bone conduction unit 300, thereby enabling adjustment to fit different body types.

[0096] It is preferable that the surface of the connecting frame 800 on the opposite side of the assembly groove 810, i.e., the opposite side of the bone conduction unit 300, and the tip of the bone conduction unit 300 are formed in a slightly convex shape to correspond to the user's sunken temples, thereby maximizing the contact area and providing stable support.

[0097] In particular, a communication hole 820 is formed in the connecting frame 800 along the extension direction at a position on the opposite side of the bone conduction unit 300 with respect to the electrical stimulation unit 400, so that the extending connecting frame 800 can be supported in more stable contact with the user's body and surrounding sounds can be heard through the communication hole 820, making it easier to avoid the risk of safety accidents.

[0098] As shown in the figure, the end of the bone conduction section 300 may be formed in a convex shape toward the temple to complement the temple of the user, and it is preferable that even when the connecting frame 800 is separated, it adheres to the user's body to smoothly perform the bone conduction function.

[0099] In a plan view, each of the connecting frames 800 can extend rearward from the bone conduction portion 300 in a shape that spreads out from each other, and is preferably configured to naturally contact the user's temples to the mastoid process.

[0100] A battery module 910 may be detachably coupled to the rear end of the ear hook 200, and a charging port 920 may be formed in the battery module 910.

[0101] This makes it easy to attach and detach the battery module 910, and since the relatively heavy battery module 910 is positioned close to the center of gravity, stability is increased and the electrical stimulation bone conduction headset (1000') can be prevented from easily coming off the head.

[0102] An auxiliary sheet portion 919 made of a flexible material similar to the sheet portion 490 of embodiment 1 is formed on the surface of the battery module 910 in the portion that comes into contact with the mastoid process, and the auxiliary sheet portion 919 and its inner bottom form a third sheet groove 911, which fits snugly against the mastoid process and prevents discomfort during use.

[0103] A locking hole 240 is formed on the side of the ear hook part 200 to which the battery module 910 is connected, and the battery module 910 may have a locking protrusion 915 formed thereon to fit into the locking hole 240.

[0104] The embodiments of the present invention are merely exemplary, and those skilled in the art will appreciate that various modifications and equivalent alternative embodiments are possible within the scope of the following claims.
