Description

Electrical Stimulation Bone Conduction Headset

[0001] The present invention relates to an electrical stimulation bone conduction headset, and more specifically, to an electrical stimulation bone conduction headset that is equipped with both a bone conduction unit and an electrical stimulation unit, and is excellent in not only preventing hearing loss through bone conduction but also treating tinnitus.

[0002] Normally, sounds heard by the human ear are transmitted in the form of waves. External sounds enter the human outer ear, causing the eardrum to vibrate. This stimulates cells in the inner ear behind the eardrum, which are then transmitted 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 use to converse with each other is approximately 500 - 2,000 Hz.

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

[0005] Therefore, bone conduction, which transmits sound through the vibration of the skull, is widely used these days.

[0006] Bone conduction is a method of transmitting sound that vibrates the skull to the cochlea and then to the brain through the auditory nerve, omitting the process of the vibration passing through the eardrum and the three bones located within the eardrum in the sound recognition mechanism.

[0007] In other words, bone conduction headsets transmit sound 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 clearly hear sound through bone conduction through the skin and bones as long as the cochlea and auditory nerve are normal.

[0008] Meanwhile, in the case of air-conductive headsets, the risk of safety accidents may increase because you cannot hear surrounding sounds because you have to cover your ears when using them.

[0009] Accordingly, in advanced countries, it is legally regulated to wear air-conductive earphones or headphones that block the ears and are used to listen to music, etc. on the road.

[0010] In addition, with the recent rapid spread of digital audio and communication devices, the number of youth suffering from noise-induced hearing loss has increased worldwide, with more than 10% of the population complaining of hearing loss. In addition, in this era of global aging, the increase in hearing loss due to the elderly has also become a social problem, and so reducing the volume and usage time of speakers that receive through air conduction is being suggested as an alternative.

[0011] Meanwhile, using a bone conduction headset keeps your ears open, so you can simultaneously receive surrounding sounds, preventing safety accidents. In addition, it can prevent hearing loss by not directly affecting the eardrum.

[0012] These bone conduction headsets transmit sound by vibrating the bones around the ear, 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 types of pain caused by various causes by stimulating the peripheral sensory nerves of the skin using electric current of a certain frequency and intensity, and is applied to various parts of the body.

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

[0015] Although the specifications of transcutaneous electrical nerve stimulation devices vary, the settings such as current pulse frequency, pulse width, stimulation intensity, treatment time, stimulation site, and electrode placement method are important considerations when performing transcutaneous nerve stimulation treatment.

[0016] For example, the waveforms that are widely used include monophasic rectangular wave, asymmetrical biphasic rectanguar wave, symmetrical biphasic rectangular wave, modified spike wave, monophasic rectangular high frequency carrier, or sine wave.

[0017] The pulse rate ranges from 10-100 pps, 20-200 pps, etc., and is usually 1-100 pps, so you can select and adjust the appropriate pulse rate.

[0018] Pulse duration is 10-200 < <S, 120-330 <<S, 50-500 <<S 등 범위가 10-600<<S로 다양하다. 비대칭성 이상 직사각형파는 50-500<<S, 단상 직사각형파는 10-100<<S의 맥동폭을 가지고 있다.

[0019] The stimulus intensity varies, including 10-50 mA, 100 mA or less, and 150 mA or less, but is usually up to 100 mA.

[0020] In addition, electrodes come in various sizes and shapes, and depending on the material, there are pad electrodes, carbon silicon electrodes, disposable paper electrodes, and Karaya gum electrodes, with carbon silicon electrodes being the most widely used.

[0021] The shape and size of the electrodes are also very diverse, including a 5cm diameter circular snap, pin shape, square, rectangular, and banana shape, so you can select and use an electrode that is suitable for the characteristics of the treatment area.

[0022] The aforementioned transcutaneous electrical nerve stimulation is known to be effective for tinnitus, ringing in the ears, and hearing loss, and so a treatment that stimulates the area around the ear has recently been performed.

[0071] According to the present invention having the configuration described above, the following effects can be obtained.

[0072] First, according to the present invention, since it is characterized by including a neckband part that wraps around the back of the user's head in a band shape, earring parts that are respectively arranged at both ends of the neckband and hang over the user's ears, a bone conduction part installed near the tip of each earring part, an electric stimulation part that is installed spaced back from the bone conduction part and has electrodes installed on the side that touches the skin, and a control part that controls the operation of the bone conduction part and the electric stimulation part, it has the advantage that it can be expected to be very effective in preventing and treating hearing loss or tinnitus, etc., because it includes both the bone conduction part and the electric stimulation part.

[0073] In addition, according to the present invention, the electric stimulation unit is installed connected to the rear end of the earring unit so that the electric stimulation unit contacts the mastoid process to electrically stimulate it, thereby enabling treatment of tinnitus, hearing loss, or ringing in the ears to be performed more effectively.

[0074] In addition, according to the present invention, since the electric stimulation unit is configured to be detachable from the earring unit, when the electric stimulation unit is detached, only the function of the bone conduction earphone can be performed, and in case of an abnormality in the electric stimulation unit, it can be detached separately and repaired or otherwise maintained.

[0075] In addition, according to the present invention, a connecting hole is formed in the upper and lower direction at the lower end of the earring portion, and the electric stimulation portion is inserted and connected through the connecting hole, and the electric stimulation portion includes a battery and a charging port for charging the battery is installed, so that the battery can be inserted into the earring portion through the connecting hole and be safely protected, and the battery for operating the electric stimulation portion can be separately charged, enabling easy charging.

[0076] In addition, according to the present invention, a mounting portion is formed around the electrode of the electric stimulation unit, and a first mounting groove is formed between the electrode and the mounting portion, so that the mounting portion is mounted facing the mastoid process, thereby enabling electric stimulation to be transmitted more effectively.

[0077] In addition, according to the present invention, since a second fixing groove is formed in the earring part to which the electric stimulation part is coupled to be fixed on the mastoid process, it is possible to avoid an unstable state of contact with the mastoid process even when the electric stimulation part is separated from the earring part.

[0078] In addition, according to the present invention, a hook hole is formed on the side of the earring part to which the electric stimulation unit is coupled, and a hook projection that fits into the hook hole is formed on the electric stimulation unit, so that when the electric stimulation unit is coupled through the coupling hole on the lower part of the earring part, the hook hole and the hook projection are engaged with each other, thereby forming a one-touch coupling, thereby enabling easy coupling of the electric stimulation unit.

[0079] In addition, according to the present invention, a switch connected to a control unit is arranged on the back of the earring part to which the electric stimulation unit is coupled, so that parameters such as the stimulation intensity, frequency, and pulse cycle of the electric pulse can be set according to the purpose.

[0080] In addition, according to the present invention, the electrical stimulation unit is characterized by being installed in a connecting frame extending backward from the bone conduction unit, so that the electrode can transmit electrical stimulation to the migratory nerve, and thus can be effective for various symptoms such as tinnitus, ringing in the ears, and hearing loss, in addition to tinnitus.

[0081] In addition, according to the present invention, the connecting frame is characterized in that it is configured to be detachable from the bone conduction unit, so that when the electric stimulation unit is detached, it can only perform the function of the bone conduction earphone, and in case of an abnormality in the electric stimulation unit, it can be detached separately and maintained, such as for repair.

[0082] In addition, according to the present invention, the bone conduction unit protrudes inward toward the user's head, and an assembly groove into which the bone conduction unit is coupled is formed in the connecting frame, so that the protruding part of the bone conduction unit is coupled to the assembly groove, and the connecting frame can freely rotate around the bone conduction unit, so that adjustment for application to different bodies is easy, and external sounds can be heard through the ear hole through the communication hole formed in the connecting frame, so that the risk of safety accidents can be avoided.

[0083] In addition, according to the present invention, the surface of the connecting frame opposite the bone conduction unit and the tip of the bone conduction unit are configured in a convex shape to complementarily correspond to the user's temple, so that the bone conduction sound transmission effect is excellent because the bone conduction sound transmission effect can be further improved by being closely attached to the skin.

[0084] In addition, according to the present invention, a battery module is detachably connected to the rear end of the earring portion, and a charging port is formed in the battery module, so that the battery can be easily attached and detached, and since the relatively heavy battery is placed close to the center of gravity, stability is increased, so that the electrical stimulation bone conduction headset can be prevented from easily coming off from the head.

[0093] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0094] As illustrated in FIGS. 1 and 5, the bone conduction electrical stimulation headset (1000) (1000') according to the present invention comprises a neckband part (100) that wraps around the back of the user's head in a band shape, earring parts (200) that are respectively positioned at both ends of the neckband (100) and hang over the user's ears, a bone conduction part (300) that is installed near the tip of each earring part (200), an electrical stimulation part (400) that is installed spaced apart from the bone conduction part (300) toward the back and has electrodes (450) installed on the side that touches the skin, and a control part (not shown) that controls the operation of the bone conduction part (300) and the electrical stimulation part (400).

[0095] According to this configuration, the electric stimulation bone conduction headset (1000) according to the present invention has both a bone conduction unit (300) and an electric stimulation unit (400), and thus has the advantage of being able to effectively prevent hearing loss due to bone conduction and treat tinnitus, hearing loss, or ringing in the ears due to electric stimulation.

[0096] Hereinafter, two embodiments of the above-described electric stimulation bone conduction headset (1000) are described, but the present invention is not limited thereto, and it is obvious that various embodiments and modifications may be made within the scope of the claims described below.

[0097] Example 1

[0098] As shown in FIGS. 1 to 4, the electric stimulation unit (400) according to the present embodiment is installed and connected to the rear end of the earring unit (200).

[0099] Accordingly, the electrical stimulation unit (400) contacts the mastoid process to electrically stimulate it, and tinnitus, hearing loss, or ringing in the ears can be effectively treated.

[0100] In particular, according to the present embodiment, the electric stimulation unit (400) is configured to be detachable from the earring unit (200).

[0101] Accordingly, when the electric stimulation unit (400) is separated, not only can it perform only the function of the bone conduction earphone, but if an abnormality occurs in the electric stimulation unit (400), it can be separated separately and repaired or otherwise maintained.

[0102] For example, as shown, a connecting hole (210) is formed in the upper and lower direction at the lower end of the earring part (200), and the electric stimulation part (400) can be inserted through the connecting hole (210) and detachably connected.

[0103] The above electric stimulation unit (400) has a built-in battery (not shown), and a charging port (420) for charging the battery can be installed.

[0104] Accordingly, the battery for operating the electric stimulation unit (400) can be charged separately, enabling easy charging.

[0105] In this case, it is preferable that the battery of the electric stimulation unit (400) is inserted into the connecting hole (210) so as not to be exposed.

[0106] The above battery may be used to operate the bone conduction unit (300), but a separate battery may be provided to operate the bone conduction unit (300).

[0107] In this case, the separate battery may be built into the neckband part (100), etc.

[0108] It is preferable that a mounting portion (490) is formed around the electrode (450) of the above-mentioned electric stimulation portion (400), and a first mounting groove (430) is formed between the mounting portion (490) and the electrode (450) so that the mounting portion (490) is mounted facing the mastoid process, thereby transmitting the electric stimulation more effectively.

[0109] The above-mentioned mounting portion (490) may be a mounting ring that protrudes in the direction in which the electrode (450) is facing along the circumference of the electrode (450) or a mounting edge having an inner wall surface along the circumference of the electrode (450).

[0110] That is, the mounting portion (490) around the electrode (450) forming the first mounting groove (430) is made of rubber or silicone material, so that the mounting portion (490) around the electrode (450) can be flexibly mounted on the inside of the lower portion of the user's mastoid process when the electrode (450) is in contact with the mastoid process.

[0111] Inside the earring part (200) to which the above-mentioned electric stimulation part (400) is connected, an electrode (450) and a wire connected to the control part and the battery are built in.

[0112] In addition, a second fixing groove (220) that is fixed to the mastoid process is formed in the earring part (200) to which the electric stimulation part (400) is coupled, so that even when the electric stimulation part (400) is separated from the earring part (200), the contact state with the mastoid process can be prevented from becoming unstable.

[0113] A hook hole (240) is formed on the side of the earring part (200) to which the electric stimulation part (400) is coupled, and a hook projection (440) that fits into the hook hole (240) may be formed on the electric stimulation part (400).

[0114] According to this configuration, when the electric stimulation part (400) is connected through the connecting hole (210) at the bottom of the earring part (200), the hook hole (240) and the hook projection (440) are connected to each other, thereby creating a click and one-touch connection.

[0115] As shown in Fig. 5, the above-mentioned hook holes (240) are formed in a plurality of pieces spaced apart from each other in the vertical direction, i.e., along the longitudinal direction of the earring portion (200), and the above-mentioned hook protrusions (440) can also be formed in a plurality of pieces spaced apart from each other along the longitudinal direction of the electric stimulation portion (400).

[0116] According to this configuration, the insertion length of the electric stimulation unit (400) through the above-mentioned connecting hole (210) can be adjusted, making it possible to appropriately respond to different body structures of different users.

[0117] That is, when the electric stimulation unit (400) is inserted at its deepest through the connecting hole (210) and the engaging hole (240) and the engaging projection (440) are combined, the electrode (450) is at its highest position, and when combined at its shallowest insertion, the electrode (450) is at its lowest position.

[0118] In this case, it goes without saying that the electrical stimulation unit (400) is configured to enable electrical and / or communication connection with the control unit and switch even if the insertion position thereof changes.

[0119] A switch (470) connected to a control unit may be placed on the back of the earring unit (200) to which the above-mentioned electric stimulation unit (400) is coupled.

[0120] In this case, the switch (470) may each include a switch that sets various parameters such as stimulation intensity, frequency, and pulse cycle of electric pulses for tinnitus treatment.

[0121] The control unit, such as a printed circuit board, may be built into the interior of an earring (200) in which an electric stimulation unit (400) is installed or may be placed inside a case in which a bone conduction unit (300) is built.

[0122] Example 2

[0123] As shown in FIGS. 5 to 8, in describing the electric stimulation bone conduction headset (1000') of Example 2, the same components as those of Example 1 are given the same component symbols and further description is omitted.

[0124] First, according to the present embodiment, the electrical stimulation unit (400) is installed in a connecting frame (800) extending rearward from the bone conduction unit (300).

[0125] That is, the above connecting frame (800) extends rearward with the bone conduction unit (300) as the center, and an electrical stimulation unit (400) including an electrode (450) is installed at a location spaced apart from the bone conduction unit (300).

[0126] Inside the above connecting frame (800), an electrode (450) and a wire connected to the control unit and battery are built in.

[0127] It is preferable that the above electrode (450) touches the user's tragus nerve area to transmit electrical stimulation, but it is not necessary to stick to that area.

[0128] Electrical stimulation can be effective not only for tinnitus but also for various other symptoms such as ringing in the ears, hearing loss, and pain relief.

[0129] Additionally, the connecting frame (800) can be configured to be detachable from the bone conduction unit (300).

[0130] Accordingly, when the electric stimulation unit (400) is separated, it is possible to perform only the function of the bone conduction earphone, and in case of an abnormality in the electric stimulation unit (400), it can be separated separately and repaired or maintained.

[0131] The above bone conduction unit (300) protrudes inward toward the user's head, and an assembly groove (810) into which the bone conduction unit (300) is coupled is formed in the connecting frame (800), so that the protruding part of the bone conduction unit (300) is coupled to the assembly groove (810), and the connecting frame (800) can freely rotate around the bone conduction unit (300), thereby enabling adjustment for application to different bodies.

[0132] It is preferable that the surface of the connecting frame (800) opposite the above assembly groove (810), that is, the opposite side of the bone conduction unit (300), and the tip of the bone conduction unit (300) be formed in a somewhat convex shape to correspond to the concave temple of the user, thereby maximizing the contact area and providing stable support.

[0133] In particular, the connecting frame (800) has a communication hole (820) formed at an opposite position of the bone conduction unit (300) based on the electric stimulation unit (400) along the extension direction, so that the extending connecting frame (800) is supported by being in contact with the user's body more stably, and surrounding sounds can be heard through the communication hole (820), so that the risk of safety accidents can be avoided more easily.

[0134] As illustrated, the end of the bone conduction unit (300) may be configured in a convex shape toward the temple to complementarily correspond to the user's temple, so that it is preferable to ensure that the bone conduction function is smoothly performed by closely contacting the user's body even when the connecting frame (800) is separated.

[0135] When viewed from a plan view, each of the above connecting frames (800) may be formed to extend from the bone conduction unit (300) in a shape that spreads apart from each other toward the rear, so that it is preferable to be configured to naturally contact the user's temples to the mastoid process.

[0136] A battery module (910) is detachably connected to the rear end of the above-mentioned earring portion (200), and a charging port (920) can be formed in the battery module (910).

[0137] Accordingly, the battery module (910) is easy to attach and detach, and the relatively heavy battery module (910) is placed close to the center of gravity, thereby increasing stability and preventing the electrical stimulation bone conduction headset (1000') from being easily detached from the head.

[0138] An auxiliary mounting portion (919) made of a flexible material similar to the mounting portion (490) of Example 1 is formed on the surface of the battery module (910) that comes into contact with the mastoid process, and a third mounting groove (911) is formed by the auxiliary mounting portion (919) and the bottom inside thereof so that the battery module fits snugly against the mastoid process, thereby eliminating any discomfort during use.

[0139] A hook hole (240) is formed on the side of the earring part (200) to which the battery module (910) is coupled, and a hook protrusion (915) that fits into the hook hole (240) may be formed on the battery module (910).
