Description

Headset for bone conduction with mask detachable means

The present invention relates to a headset for bone conduction having a mask detachable means, and more particularly, to a mask that clearly transmits sound vibrations in contact with the mastoid and prevents viruses or harmful substances from entering the respiratory tract. It relates to a headset for bone conduction having a mask detachable means capable of this.

In general, a headset for bone conduction transmits sound through vibration of the skull, and when the sound that vibrates the skull is transmitted to the cochlea, the auditory nerve transmits it to the brain. In other words, since it transmits sound by vibrating the bones around the ear, it can be usefully used not only by the hearing impaired but also by people who work in noisy places.

This headset for bone conduction is formed with a speaker provided with a vibrator at both ends of a headband worn on the head, and consists of a microphone extending from one of the speakers.

That is, when the speaker is closely attached to a portion of the skull, the vibrator provided in the speaker directly vibrates the skull rather than the eardrum in the ear, so that the user can hear the sound through the vibration.

Conventionally, since the bone conduction headset performs only a simple sound transmission function, it is difficult to implement various functions. There was an inconvenience that had to be done.

On the other hand, the mask is a protective article used to protect the wearer's face by blocking the cold in winter or to prevent bacteria or dust in the air from being inhaled into the human body through breathing.

In recent years, interest and demand for functional masks are increasing day by day as respiratory-related diseases such as corona virus spread along with high fine dust concentrations, and these masks are usually worn through the ears of users.

However, since both the bone conduction headset and the mask are worn over the user's ear, there is a very inconvenient problem in additionally wearing or taking off any one of the bone conduction headset and the mask.

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

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying Figures 1 to 11.

As shown, the bone conduction headset having a mask detachable means according to the present invention is a pair of module body 200 having a mask fixing means 210 for fixing both ends of the mask 100 covering the periphery of the respirator. ), a pair of bone conduction frames 300 having a bone conduction unit 310 that is in close contact with the mastoid process behind the user's ear and transmits sound by vibration, between the module body 200 and the bone conduction frame 300 It is configured to include an earring seat 400 for tensioning the fracture degree frame 300 toward the mastoid process, and a connection band 500 for interconnecting the module body 200 or the bone conduction frame 300. .

First, the module body 200 is located on the temple side in front of the ear with respect to the user's ear, and a battery 201 control board for supplying power necessary for the operation of the bone conduction unit 310 and the microphone ( ), which will be described later. (202) and the like are installed.

The module body 200 consists of a pair of components positioned on both sides of the user's head.

A battery 201 is installed in one of the pair of module body 200 and a control board 202 corresponding to the weight of the battery 201 is installed in the other. This is to allow the two module main bodies 200 to stably maintain a weight balance without weight deviation.

The module body 200 according to the present invention protects the wearer's face by blocking the cold in winter or covers the periphery of the respirator to prevent airborne bacteria, viruses, dust, etc. from being inhaled into the human body through the respirator (100) It further includes a mask fixing means 210 for fixing both ends of the.

The mask fixing means 210 is to removably fix the mask 100, and forms a mask entry space 211 into which the mask enters in the width direction of the module body 200, and enters the mask A cover 212 for opening and closing is formed in which one side of the module body 200 hinges in one direction with respect to the space portion 211 .

That is, the mask 100 entering the mask entry space 211 of the module body 200 removes the mask 100 from the pressure in which the opening/closing cover 212 elastically presses one side of the mask. It may be fixed to the module body 200 .

In other words, the opening and closing cover 212 rotates outward to secure a space so that the mask 100 can stably enter the mask entry space 211, and then when the entry of the mask is completed, the opening and closing cover ( 212 is rotated again in the direction toward the module body 200 to fix the mask from the pressure that presses the mask 100 .

In addition, as shown in FIGS. 4 and 5 , a blocking protrusion 211a protruding outward is formed on one side of the module body 200 forming the mask entry space 211 , and the mask 100 . And each of the mask locking grooves 100a and the cover locking grooves 212a corresponding to the locking projections 211a are formed in the opening and closing cover 212 . Accordingly, the mutual binding force between the mask 100 and the module body 200 can be greatly increased by the locking protrusions 211a and the

respective locking grooves

100a and 212a.

In addition, the opening and closing cover 212 may be installed in the module body 200 in a detachable coupling structure using the attractive force of the magnet M rather than rotating by the hinge.

That is, one side of the module body 200 and one of the opening and closing covers 212 facing the one side may be provided with a magnet M, and a metal corresponding to the magnet may be installed on the other.

In addition, the mask fixing means 210 can be manufactured in a sliding fastening structure in which the opening and closing cover 212 is slid in the vertical direction or the lateral direction to be detachably coupled.

In addition, a temperature sensor 230 that detects the user's body temperature in real time and transmits the sensed temperature to the control board 202 is installed in any one of the module body 200 (see FIG. 6 ).

The mask 100 according to the present invention is detachably coupled to the mask fixing means 210 of the module body 200, and can be made of various materials such as synthetic fibers, copper fibers, and leather.

A mask support 110 is installed inside the mask 100 to prevent the mask from flowing toward the user's respiratory tract.

That is, the mask support part 110 prevents the flow of the mask and always secures a certain space to give discomfort to breathing, or in the case of a female wearer, prevents the inner surface of the mask 100 from being easily contaminated by cosmetics such as lipstick. It provides an effect that can be done.

Locking pieces 120 provided with fitting gaps are formed in the upper and lower portions of the mask 100 , and fixing pieces 111 fitted to correspond to the locking pieces 120 are formed on the mask support part 110 .

In addition, although not shown in the drawings, a removable intermediate filter may be additionally configured in the mask support unit 110 .

That is, the removable intermediate filter filters the external air introduced through the mask 100 once again to fundamentally block viruses, etc. from entering the wearer's respiratory tract, and the mask by droplets scattered through the wearer's respiratory tract. (100) It prevents the inside from being contaminated and provides the effect of hygienically managing the mask for a long time.

In addition, the air passage closing part 130 is formed inside the mask 100 to elastically deform in response to the curved surface of the user's nose so that the surface can be closely adhered.

That is, when the user breathes while wearing the mask 100, warm and humid air is generated. At this time, the warm and humid air escapes upward through the air passage formed by the height difference between the user's face and the bridge of the nose. As a result, in the case of a user who wears glasses, fogging occurs in the glasses, which makes it difficult to secure a field of view, and thus serves to close the air passage.

The air passage closing part 130 is preferably made of soft silicone having a predetermined thickness, but is not necessarily limited thereto and may be made of various materials having excellent elastic deformation.

In addition, as shown in FIGS. 7 and 8 , the mask may have a foldable upper wing 140 and a lower wing 150 therein so that the mask 100 can be expanded and unfolded in the vertical direction.

On the other hand, the bone conduction frame 300 is a base member on which the bone conduction unit 310 for transmitting sound by vibration is installed in close contact with the mastoid process behind the user's ear.

The bone conduction unit 310 is a vibrating speaker that converts an input electrical sound signal into a vibration signal, unlike a conventional air conduction type speaker, transmits vibration to the skull so that the sound can be heard without passing through the ear, and the specific configuration thereof And since the operation is the same as or similar to that of the known prior art, the configuration and operation description will be omitted.

This bone conduction unit 310 is located in the mastoid process closer to the cochlea rather than the temple position, so that it is possible to further increase the listening efficiency of sound by transmitting vibrations, and when the user wearing the bone conduction headset is viewed from the front, the bone conduction unit Since 310 is not visible, there is an effect of greatly increasing the aesthetics.

In addition, the bone conduction frame 300 is detachably coupled to the outer periphery of the bone conduction unit 310 and transmits the sound wave output from the bone conduction unit 310 to the auricle cartilage and the temporal part facing the auricle. It further includes an ear bone conduction unit 350 .

The ear bone conduction unit 350 is detachably coupled with respect to the circumferential direction of the bone conduction unit 310, and transmits the sound wave output from the bone conduction unit 310 to the auricle cartilage to improve the listening efficiency of the sound. It provides a significant improvement effect.

That is, the ear bone conduction unit 350 serves to transmit the vibration transmitted from the bone conduction unit 310 to the auricle cartilage and the temporal region, respectively, while being coupled to the circumferential surface of the bone conduction unit 310 .

Specifically, the ear bone conduction unit 350 includes a body portion 351 having a coupling penetration portion corresponding to the bone conduction portion 310, and the ear extending from the body portion 351 and extending in a curved direction so as to span the auricle. It consists of a hook part 352 , the body part 351 , and a vibration plate 353 embedded in the ear hook part 352 .

The ear hook 352 has a sectional thickness that gradually decreases from the body portion 351 toward the end, and is bent with both sides in the longitudinal direction maintaining an acute angle in order to be easily fixed between the pinna and the temporal part. is good Due to this, it is possible to increase the fit and tightness of the ears in response to different ear shapes and curved surfaces for each user.

The vibration plate 353 is preferably manufactured in a plurality of configurations that are branched in a direction toward the end of the ear hook 352 .

In addition, the bone conduction frame 300 has a locking protrusion 360 protruding to the outside is formed, and an elastic band 370 for elastically connecting the mask or the module body is installed in the locking protrusion 360 .

That is, the gap between the mask 100 or the module body 200 and the bone conduction frame 300 can always be elastically maintained by the elastic band 370 , and the mask 100 or the module body 200 . And it is possible to prevent the bone conduction frame 300 from spreading outward.

One end of the elastic band 370 may be connected in a state of being caught by the locking protrusion 360 of the bone conduction frame 300 , and the other end may be selectively connected to the mask 100 or the module body 200 .

When the elastic band 370 is connected to the mask 100, a band hole 101 into which the elastic band 370 is fitted is formed in the mask 100, and when connected to the module body 200, the module body 200 ), a separate hook 205 or a rubber plate is additionally formed (see FIGS. 3 and 9).

On the other hand, the earring seat 400 serves to electrically connect the module body 200 and the bone conduction frame 300 and also to press the tension of the fracture frame 300 toward the mastoid process.

Specifically, the earring receiving unit 400 includes a first support 410 that is inclined downward in front of the ear and a second support 420 that is inclined downward toward the rear of the ear based on the top dead center that is over the user's ear when viewed from the side. ), and when viewed from a plan view, the second supporter 420 is curved inward than the first supporter 410 (see FIGS. 10 and 11 ).

That is, when the user wears glasses, the longitudinal direction of the temple (B) and the longitudinal movement of the earring mounting part 400 do not overlap each other, thereby minimizing the inconvenience in wearing glasses, and the second The structure in which the support 420 is curved toward the user's head rather than the first support 410 is to more efficiently apply the elastic pressure in which the bone conduction unit 310 is in close contact with the mastoid process.

In addition, a slope inclined surface 401 is formed on one side of the upper side in the width direction of the earring receiving part 400 .

When the user wears glasses, the slope slanted surface 401 serves to allow the temple to be worn in a state where the temples are placed on the earring receiving part 400 without contacting the user's lateral scalp.

In other words, even if the temple (B) is worn in a direction in which it is in close contact with the user's scalp, the temple (B) naturally moves in the direction away from the user's side scalp by the slope slanted surface 401, B) can fundamentally block the pressure that presses the user's lateral scalp.

The connecting band 500 is a component that electrically connects the module body 200 or the bone conduction frame 300 to each other.

When the connection band 500 connects the bone conduction frame 300, the connection band 500 may be positioned at the back surrounding the user's back neck.

In this case, since the connection band 500 is located on the back of the user's neck, it serves as a necklace for the user to mount the bone conduction headset on the neck for an arbitrary time.

In addition, when the connection band 500 connects the module body 200, the connection band is positioned in front of the mask 100 through the mask 100 to maintain a neat appearance so that the connection band 500 is not exposed to the outside. It is desirable to make it possible (see FIG. 8).

And, as shown in FIG. 8 , a Velcro fixing part 141 is formed on the mask 100 to prevent the connection band 500 passing through the gap of the upper wing 140 from flowing.

That is, the Velcro fixing part 141 serves to prevent the connecting band 500 from flowing in the vertical direction.

In addition, a microphone 510 is installed in the longitudinal center of the connection band 500 .

That is, since the microphone 510 is located on the side of the mask 100 , there is a very excellent effect of accurately recognizing the user's voice signal even when the user wears the mask 100 .

The present invention described above is not limited by 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 those of ordinary skill in the art.
