Description

Bone conduction headset}

The present invention relates to a headset for bone conduction, and more specifically, not only can it flexibly respond to different occipital size and mastoid position for each user, but also prevents vibration generated when sound output from the bone conduction unit from being transmitted to the body frame. It relates to a bone conduction headset that helps treat diseases such as tinnitus, hearing loss, and headaches by stimulating the acupoints around the ears.

Generally, sounds heard by the human ear are transmitted in the form of waves. External sounds enter through the human outer ear and vibrate the eardrum, and cells in the inner ear inside the eardrum are stimulated and transmitted to the brain. The frequency range of sounds that humans can hear is about 20 - 20,000 Hz, and the frequency range of sounds that humans communicate with is about 500 - 2,000 Hz.

However, in the case of a hearing impaired person, he or she may not be able to hear all or some frequencies within the frequency range of sound. Therefore, recently, bone conduction, which transmits sound through vibration of the skull, has been used.

Bone conduction is a method in which sound that vibrates the skull is transmitted to the cochlea and then to the brain via the auditory nerve. Since it transmits sound by vibrating the bones around the ears, it can be useful not only for the hearing impaired but also for people who work in noisy places.

Meanwhile, the conventional first bone conduction type headset (Korean Patent Publication No. 1849041) simply provides a function to improve the output of the bone conduction unit that transmits sound, so it may be used when the user engages in vigorous exercise or makes irregular movements. There was an inconvenience in that the position of the bone conduction headset had to be frequently corrected due to the phenomenon of falling down, and in particular, there was a problem of causing headaches due to the bone conduction unit continuously putting pressure on the user's temple area.

In addition, the conventional second bone conduction type headset (Korean Patent Publication No. 0921524) improves the adhesion between the user and the bone conduction speaker, so that pain in the user's temple area can be suppressed by the head holder and ear band. The technology for configuring each length adjustment unit and angle adjustment unit has been published.

However, the conventional second bone conduction type headset can reduce pain in the user's temple area by adjusting the width of the ear band according to the size of the head, but the phenomenon of speakers moving due to exercise or irregular movements still occurs. There is a problem that arises.

In addition, the conventional bone conduction headset applied by the present applicant (Korean Patent Publication No. 1215270) has published a technology that allows the bone conduction unit to adhere closely to the user's mastoid process, thereby significantly improving sound listening efficiency.

however. In the conventional bone conduction headset, the protruding frame on which the bone conduction unit is installed is made of hard synthetic resin, so not only did it have a structural problem in that it was difficult to flexibly respond to the different sizes of the occiput and mastoid process for each user, but also the output from the bone conduction unit was difficult. Vibration was transmitted through the protruding frame to the connection band, causing howling, making it difficult to provide quality sound.

Republic of Korea Patent Publication No. 1849041 (2018.04.09) Republic of Korea Patent Publication No. 0921524 (2009.10.06) Republic of Korea Patent Publication No. 2115270 (2020.05.20)

The present invention was developed to solve the above problems, and not only can flexibly respond to different occipital size and mastoid position for each user, but also prevents the vibration generated when sound output from the bone conduction unit from being transmitted to the body frame. The goal is to provide a headset for bone conduction that prevents bone conduction.

In addition, the goal is to provide a bone conduction headset that helps treat diseases such as tinnitus, hearing loss, and headaches by stimulating the acupoints (yepung acupuncture points) around the user's ears using bone conduction units.

In order to achieve the above-described object, a bone conduction headset according to the present invention includes a body frame extending in a curved direction to surround the back of the head; an earring frame connected to both ends of the main body frame and forming a protruding coupling portion at the lower portion; An elastically variable connector installed between the main body frame and the earring frame; a flexible extension part removably coupled to the protruding coupling part of the earring frame and extending in a direction toward the mastoid process behind the user's ear; A bone conduction unit installed on the flexible extension part and in close contact with the user's mastoid process to transmit sound through vibration; And an ear bone wing that is detachably coupled to the circumferential direction of the bone conduction unit and transmits sound waves output from the bone conduction unit to the auricular cartilage, wherein the flexible extension part responds to pressure applied by an external force. It is characterized by being made of rubber or silicone, which undergoes proportional elastic deformation.

The bone conduction unit includes a dome housing that forms a receiving space inside and a closed end that protrudes convexly to the outside, a vibrator accommodated and installed in the receiving space, and one side is inserted into the receiving space in a state of pressurizing and supporting the vibrator, and the other side. It is characterized by being composed of a fixing bracket protruding outward, and a frequency variable substrate installed on the other side of the fixing bracket and lowering or amplifying the sound frequency of the vibrator.

A groove in which the bone conduction unit is installed is formed in the flexible extension part, and a vibration absorption member to block noise and vibration is installed inside the groove.

The vibration sound-absorbing member includes a sound-absorbing member installed on one side of the frequency variable substrate, a first sponge installed on one side of the sound-absorbing member, and a second sponge installed on one side of the first sponge and having larger air holes than the first sponge. It is characterized by being composed of:

A conductive plating layer is formed around the outer circumference of the dome housing, which can indirectly stimulate the acupuncture point (Yepung acupoint) located around the ear by transmitting microcurrent and heat to the mastoid process.

The ear bone wing forms a housing receiving portion for accommodating the dome housing, and includes a coupling body forming a coupling portion complementary to the dome housing on the inner edge, and an ear extending from the coupling body and extending in a curved direction to span the auricle. It is characterized by being composed of a close contact part and an acupoint pressurizing contact part extending from the coupling body and forming surface contact with the position of the acupoint (Yepung acupoint).

The pressure contact part of the acupoint is characterized by a conductive stimulation terminal installed through which microcurrent and heat can directly stimulate the acupuncture point (Yepung acupoint).

According to the present invention configured as described above, the elastically variable connector and the flexible extension part connecting the main body frame and the earring frame are made of rubber or silicone that is easily elastically deformed, so that they fit the curved lines of the head that are different for each individual. The earring frame can be elastically opened or closed, suppressing pain caused by local pressure, and preventing vibrations generated from the bone conduction unit from being transmitted to the main body frame, fundamentally blocking the resulting howling phenomenon. There is an effect that can be achieved.

In addition, since the bone conduction unit is composed of a convexly protruding dome housing, a fixing bracket, and a frequency variable substrate, not only can it be closely attached in various directions to correspond to the convexly protruding protrusion of the mastoid process, but the frequency variable substrate is As it is installed on the outside of the dome housing by a fixing bracket, there is an effect of suppressing vibration of the frequency variable substrate due to vibration of the vibrator as much as possible.

In addition, by forming a vibration sound-absorbing member in the groove of the flexible extension, transmission of vibration and sound output by the bone conduction unit to the flexible extension is suppressed as much as possible, thereby providing high-quality sound, and preventing the bone conduction headset from being dropped on the floor. In this case, the vibration sound-absorbing member can absorb and disperse shock, thereby preventing the bone conduction unit from being easily damaged, thereby further improving the durability of the product.

In addition, the dome housing is comprised of a conductive plating layer that generates microcurrent and heat, thereby physically stimulating the Yepunghyeol (the hollow point behind the ear) located behind the ear, thereby improving the circulation of Qi and blood going up the head, thereby relieving headaches. Not only does it help treat various facial diseases such as dizziness, toothache, dry eyes, and facial paralysis, but it also provides direct treatment by providing therapeutic stimulation to patients suffering from tinnitus or hearing loss symptoms, and is also of great help in prevention. It has an effect.

It should be understood that there may be various equivalents and variations.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached FIGS. 1 to 8.

As shown, the bone conduction headset according to the present invention includes a body frame 100 extending in a curved direction to surround the back of the head, connected to both ends of the body frame 100, and having a protruding coupling portion 210 at the bottom. The formed earring frame 200, the elastically variable connector 300 installed between the main body frame 100 and the earring frame 200, and the protruding coupling portion 210 of the earring frame 200 are detachably coupled to each other. A flexible extension part 400 extending in a direction toward the mastoid process behind the user's ear, a bone conduction unit 500 installed on the flexible extension part 400 and in close contact with the user's mastoid process to transmit sound through vibration, It is detachably coupled to the circumferential direction of the bone conduction unit 500 and includes an ear bone wing (600) that transmits sound waves output from the bone conduction unit 500 to the auricular cartilage.

First, the main body frame 100 extends in a curved direction to surround the back of the user's head, and is made of a hard plastic material.

A battery and a control module for supplying power are basically installed inside the main body frame 100, and on the outside, a charging female terminal 110 for supplying the necessary power to the battery and for operating the power and control module are installed. An operation control unit 120 is formed.

The earring frame 200 is connected to both ends of the main body frame 100, and part of the earring frame 200 extends to span the user's ear and the other part protrudes downward toward the mastoid process behind the user's ear. ) is formed.

A microphone (not shown) that receives sound from the outside is installed in the earring frame 200. And at the end of the protruding coupling part 210 protruding from the lower surface of the earring frame 200, a coupling groove 211 is formed into which the flexible extension part 400, which will be described later, is fitted.

The elastically variable connector 300 is installed between the main body frame 100 and the earring frame 200, and serves to allow the earring frame to elastically open or close in accordance with the curved line of the head, which is different for each individual. Perform (see Figure 3).

For this purpose, the elastically variable connector 300 is preferably made of rubber or silicone material.

As the elastically variable connector 300 according to the present invention is made of rubber or silicon, it prevents vibration generated from the bone conduction unit 500, which will be described later, from being transmitted to the main body frame 100, resulting in a howling phenomenon. It provides the advantage of being able to fundamentally block.

The flexible extension part 400 is removably installed on the protruding coupling part 210 of the earring frame 200, and extends a predetermined length to where the mastoid process is located behind the user's ear.

A groove 410 in which the bone conduction unit 500 is installed is formed in the flexible extension part 400, and a vibration absorption member 420 is installed inside the groove 410 to block noise and vibration.

Specifically, the vibration sound-absorbing member 420 is a sound absorption member 421 installed in contact with one side of the frequency variable substrate 540, which is a component of the bone conduction unit 500, and one side of the sound absorption member 421. It consists of a first sponge 422 installed in, a second sponge 423 installed on one side of the first sponge 422 and having larger air holes than the first sponge 422.

This vibration sound-absorbing member 420 provides high-quality sound by maximally suppressing transmission of vibration and sound output from the bone conduction unit 500 to the flexible extension part 400.

Moreover, not only can the vibration and sound transmitted to the outside be dispersed more effectively due to the compression deviation of the air holes of the first sponge 422 and the second sponge 423, but also the bone conduction headset can be damaged due to the user's carelessness. When dropped on the floor, the bone conduction unit 500 can be prevented from being easily damaged due to the structure of the upper limb first and second sponges 422 and 423, which has the effect of further improving the durability of the product.

The flexible extension part 400 according to the present invention is made of rubber or silicone that undergoes elastic deformation in proportion to the pressure applied by an external force.

That is, the flexible extension part 400 is made of an elastic material different from the material of the main body frame 100, so the flexible extension part 400 does not press the user's mastoid process with strong pressure, thereby causing direct pain to the mastoid process. It does not cause irritation and provides the effect of being comfortable to wear even when used for a long time.

In addition, the flexible extension part 400 also provides a very useful effect in blocking vibration generated in the bone conduction unit 500 from being transmitted to the main body frame 100.

Meanwhile, the bone conduction unit 500 is installed in the groove 410 of the flexible extension unit 400, and is in close contact with the user's mastoid process to transmit sound through vibration.

This bone conduction unit 500, unlike a typical air conduction type speaker, has a vibrator 520 that converts an input electrical sound signal into a vibration signal and transmits vibration to the mastoid process of the skull, allowing sound to be heard without going through the ears. .

Specifically, the bone conduction unit 500 includes a dome housing 510 that forms a receiving space inside and a closed end protruding convexly outward, a vibrator 520 accommodated and installed in the receiving space, and the vibrator 520. A fixing bracket 530, one side of which is inserted into the receiving space and the other side protruding outward, in a pressurized and supporting state, is installed on the other side of the fixing bracket 530 and lowers or amplifies the sound frequency of the vibrator 520. It consists of a frequency variable substrate 540.

The dome housing 510 serves to prevent the vibrator 520 from being directly exposed to and contaminated by external foreign substances (dust, moisture, etc.) by accommodating the vibrator 520 inside.

The dome housing 510 according to the present invention has a structure in which the closed end protrudes convexly, thereby providing the effect of being able to adhere closely to the mastoid process in various directions through the convex curved surface.

In other words, the shape and size of the mastoid process are different for each user, so the contact surface in contact with it is curved rather than flat, which has the effect of increasing contact efficiency with respect to the contact area.

The fixing bracket 530 is interposed between the vibrator 520 and the frequency variable substrate 540, and prevents the vibration of the vibrator 520 from having a direct adverse effect on the frequency variable substrate 540.

To this end, the fixing bracket 530 is formed in the form of a hollow tube with a circular cross-section where the diameter of one end is smaller than the diameter of the other end.

In addition, the fixing bracket 530 is manufactured with an empty interior, and the connection part connecting one end and the other end is also preferably manufactured as a bridge that forms an empty space.

The frequency variable substrate 540 is installed on the other side of the fixing bracket 530 and serves to lower or amplify the sound frequency of the vibrator 520.

In other words, it serves to set the low and high tones of the sound in various ways by allowing the sound frequency of the vibrator to be additionally set.

A conductive plating layer 511 is formed around the outer circumference of the dome housing 510 according to the present invention, which can indirectly stimulate the acupuncture point (Yepung acupoint) located around the ear by transferring microcurrent and heat to the mastoid process.

That is, by causing current stimulation by micro-current and heat by current resistance to be generated in the dome housing 510, the Yepung acupuncture point located behind the ear (the hollow point behind the ear) is physically stimulated to cause Qi blood to rise above the head. By improving circulation, it not only helps treat various facial diseases such as headaches, dizziness, toothache, dry eyes, and facial paralysis, but also provides therapeutic stimulation to patients suffering from tinnitus or hearing loss, allowing treatment and prevention. It also provides a helpful effect in doing so.

Meanwhile, the ear bone wing 600 is removably coupled to the circumferential direction of the bone conduction unit 500, and transmits sound waves output from the bone conduction unit 500 to the auricular cartilage to improve sound listening efficiency. It plays a significant improving role.

Specifically, the ear bone wing 600 forms a housing receiving portion 611 that accommodates the dome housing 500, and a coupling portion 612 that is complementary to the dome housing 510 is formed on the inner edge. a coupling body 610, an ear contact portion 620 extending from the coupling body 610 and extending in a curved direction to span the auricle, and extending from the coupling body 610 to the position of an acupoint (Yepung acupoint). It consists of an acupoint pressure contact part 630 that is in close contact with the surface.

The pressure contact portion 630 of the acupuncture point bends a portion of the longitudinal direction protruding from the coupling body 610 so as to be in close contact with the position of the Yepung acupoint.

The acupuncture pressure contact portion 630 not only transmits the pressing force that stimulates the wind type, but also provides stable support that prevents the coupling body 610 from rotating relative to the dome housing 510.

In addition, as shown in FIG. 6, a conductive stimulation terminal 631 is installed in the acupoint pressure contact portion 630, which can directly stimulate the acupoint (Yepung acupoint) with microcurrent and heat.

That is, by additionally installing the conductive stimulation terminal 631 on the acupuncture point pressure contact part 630, the stimulating effect on the Yepung acupoint is concentrated, thereby providing the effect of further maximizing the beneficial effects of stimulating the acupoint.

As shown in FIGS. 7 and 8, the earring frame 200 may additionally include a packing member 700 that is removably fitted from an end of the earring frame.

The packing member 700 forms a fitting hole 710 through which the earring frame 200 passes, and a locking protrusion 720 that is caught on the user's front ear is formed.

The packing member 700 is preferably made of a synthetic resin material with high friction so that it can be smoothly deformed in response to the curved surface of the skin in contact with the user's ear and can prevent slippery even when worn for a long time. do.

In other words, by additionally configuring the packing member 700, it is possible to prevent the bone conduction headset draped over the user's ear from coming off, thereby maintaining a stable sense of safety even during vigorous exercise.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible without departing from the technical spirit of the present invention. It will be clear to a person with ordinary knowledge.
