Description

Technical Field

[0001] This invention relates to the field of headphone equipment technology, specifically to a headband-style noise-protective headset and its usage method. Background Technology

[0002] A headband noise-protective headset is a personal protective device worn on the head that covers both ears. Its core function is to actively and / or passively reduce external environmental noise entering the ears to protect hearing, improve concentration, or achieve clear communication. It combines the functions of a hearing protector, audio headphones, and communication equipment.

[0003] To ensure effective sound isolation, most headsets use a foam pad that fits snugly against the user's skin. However, in noisy environments, especially when the user is wearing glasses, the glasses' stems can sit between the skin and the foam pad, compressing the pad and disrupting the seal. This can increase the gap between the foam pad and the skin, affecting the overall sound isolation and reducing the headset's sound isolation efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a head-mounted noise protection headset and its usage method to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a headband-style noise-protection headset, comprising two main bodies, with an adjustment frame rotatably connected to the top of each main body, and further comprising:

[0007] A sliding mechanism is installed on the side wall of the main body to prevent sound leakage caused by gaps between the device and the patient's skin when worn.

[0008] An auxiliary mechanism is installed on the side wall of the sliding mechanism to prevent excessive pressure on the patient when the device is worn.

[0009] Furthermore, the main body includes:

[0010] The fixing component is installed on the side wall of the main body.

[0011] Furthermore, the sliding mechanism includes a corrugated plate disposed on the side wall of the main body, and the sliding mechanism also includes:

[0012] The connecting component is installed on the side wall of the corrugated plate.

[0013] Furthermore, the auxiliary mechanism includes several fixing rods disposed on the side wall of the fixing component, and the auxiliary mechanism also includes:

[0014] The push component is installed on the side wall of the fixed rod;

[0015] The limiting component is installed on the side wall of the pushing component.

[0016] Furthermore, the fixing component includes four fixing blocks fixedly connected to the side wall of the main body, and the four fixing blocks are arranged in a circular array with the middle of the main body as the center;

[0017] Four fixing plates are fixedly connected to the side of the main body near the fixing block;

[0018] Four fixing plates are fixedly connected to fixing rings on the side away from the main body, and the side walls of the fixing rings have several round holes.

[0019] Furthermore, the corrugated sheet is rotatably connected to the outer surface of one of the four fixed plates;

[0020] A torsion spring is fixedly connected to the side of the wave plate closest to the main body, and the end of the torsion spring away from the wave plate is fixedly connected to the side wall of the main body.

[0021] The connecting assembly includes several elastic plates that are fixedly connected to the sidewall of the corrugated sheet;

[0022] Among them, several elastic plates are arranged in groups of four in a circular array with the center of the wave plate as the center, and an auxiliary ring is fixedly connected to the side wall of each group of elastic plates.

[0023] Two auxiliary rings are fixedly connected to leather sleeves on the side away from the main body.

[0024] Furthermore, the fixing rod is slidably connected inside the circular hole;

[0025] The pushing component includes a second fixed plate that is slidably connected to the outer surface of the fixed rod, and a return spring is fixedly connected to the side of the second fixed plate near the adjusting frame;

[0026] The end of the return spring away from the second fixed plate is fixedly connected to the side wall of the fixed ring, and an arc-shaped spring piece is fixedly connected to the side of the second fixed plate away from the right-angle block;

[0027] The side of the curved spring piece closest to the second fixing plate comes into contact with the side wall of the fixing rod.

[0028] Furthermore, a right-angled block is fixedly connected to the end of the fixing rod away from the second fixing plate;

[0029] The inclined surface of the right-angle block contacts the side wall of the wave plate, and an arc-shaped spring is fixedly connected to the end of the fixing plate away from the right-angle block.

[0030] Furthermore, the limiting component includes two inclined blocks fixedly connected to the side of the fixed plate near the right-angle block;

[0031] Among them, two rectangular plates are fixedly connected to the side of the fixed plate near the inclined block, and sliding rings are slidably connected to the outer surfaces of several rectangular plates.

[0032] Furthermore, a method of using a headband-style noise-protective headset, the method comprising the following steps:

[0033] S1: Installing foam: First, fill the inside of the leather case with sound-insulating foam, and then install sound-insulating pads between the auxiliary ring and the main body. The sound-insulating pads can prevent sound leakage between the main body and the auxiliary ring when the user wears it.

[0034] S2: Height Adjustment: The user then adjusts the height between the main body and the adjustment frame according to their own needs;

[0035] S3: Wearing and use: When wearing, the leather cover is placed over the user's ears and made to make close contact with the patient's skin, thereby achieving the purpose of sound insulation for the user.

[0036] The present invention has the following beneficial effects:

[0037] 1. In this invention, when the auxiliary ring drives the leather case to rotate, the rotation of the leather case causes the part of the leather case in contact with the user's skin to twist and wrinkle. Through the twisting of the leather case and the formation of surface wrinkles, the leather case can wrap and fill the eyeglass temples around the user's skin, thereby ensuring that the leather case and the internal sound-insulating sponge fit tightly against the patient's skin, reducing the tightness of the seal between the leather case and the user's skin, and also improving the isolation effect of the main body through the leather case and the internal sound-insulating sponge against external sound, thus improving the isolation efficiency of the headset against external sound.

[0038] 2. In this invention, when the other multiple fixing plates slide, they can push the leather cover around the eyeglass pole outward, thereby reducing the wrinkles generated by the leather cover in areas other than the eyeglass pole, which could cause excessive pressure or indentations on the user's skin during long-term wear. This can improve the patient's comfort during long-term wear while ensuring a tight fit between the leather cover and the user's skin.

[0039] 3. The present invention, by generating a reverse pushing force on the right-angle block and the fixing rod, can ensure the tightness of the direct contact between the fixing plate two and the patient's skin through the leather sleeve. This reduces the possibility of the leather sleeve sliding between the user's skin when multiple fixing plates two slide outward and push the leather sleeve. This ensures a tight fit between the leather sleeve surface and the user's skin, while increasing the contact area between the leather sleeve and the user's skin and the sound isolation efficiency when the user wears it.

[0040] 4. The present invention, through the elastic movement formed by the arc-shaped spring sheet on the two side walls of the fixing plate, can reduce the excessive wearing pressure and continuous compression on the patient caused by the wave sheet pushing the fixing plate two under the obstruction of the fixing block, thereby further improving the patient's comfort when wearing it.

[0041] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Please see Figure 1 - Figure 10 As shown, the present invention is a headband-style noise-protection headset, comprising two main bodies 1, with an adjustment frame 101 rotatably connected to the top of the two main bodies 1, and further comprising:

[0057] The sliding mechanism 2 is installed on the side wall of the main body 1 to prevent sound leakage caused by gaps between the device and the patient's skin when worn.

[0058] The auxiliary mechanism 3 is installed on the side wall of the sliding mechanism 2 to prevent excessive pressure on the patient when the patient wears it.

[0059] Entity 1 includes:

[0060] Fixing component 11 is installed on the side wall of the main body 1.

[0061] The sliding mechanism 2 includes a corrugated plate 201 disposed on the side wall of the main body 1, and the sliding mechanism 2 also includes:

[0062] Connection component 21 is installed on the side wall of the corrugated plate 201.

[0063] The auxiliary mechanism 3 includes a plurality of fixing rods 301 disposed on the side wall of the fixing component 11, and the auxiliary mechanism 3 also includes:

[0064] Push component 31 is installed on the side wall of fixed rod 301;

[0065] Restriction component 32 is installed on the side wall of push component 31.

[0066] The fixing component 11 includes four fixing blocks 111 fixedly connected to the side wall of the main body 1, and the four fixing blocks 111 are arranged in a circular array with the middle of the main body 1 as the center.

[0067] Four fixing plates 112 are fixedly connected to the side of the main body 1 near the fixing block 111;

[0068] Four fixing plates 112 are fixedly connected to fixing rings 113 on the side away from the main body 1. The side wall of the fixing rings 113 has several round holes.

[0069] The corrugated plate 201 is rotatably connected to the outer surface of the four fixed plates 112;

[0070] A torsion spring is fixedly connected to the side of the wave plate 201 near the main body 1, and the end of the torsion spring away from the wave plate 201 is fixedly connected to the side wall of the main body 1.

[0071] The connecting component 21 includes a plurality of elastic plates 211 fixedly connected to the side wall of the corrugated plate 201;

[0072] Among them, a number of elastic plates 211 are arranged in groups of four in a circular array with the center of the wave plate 201 as the center, and an auxiliary ring 212 is fixedly connected to the side wall of each group of elastic plates 211.

[0073] Among them, the two auxiliary rings 212 are fixedly connected to the leather sleeve 202 on the side away from the main body 1. When the protruding part of the wave plate 201 is pushed by the right-angle block 312, the wave plate 201 will drive the leather sleeve 202 to rotate through the elastic plate 211 and the auxiliary ring 212.

[0074] The fixing rod 301 is slidably connected inside the circular hole;

[0075] The pushing component 31 includes a fixing plate 311 that is slidably connected to the outer surface of the fixing rod 301. A return spring is fixedly connected to the side of the fixing plate 311 near the adjusting frame 101.

[0076] The end of the return spring away from the second fixing plate 311 is fixedly connected to the side wall of the fixing ring 113, and the side of the second fixing plate 311 away from the right angle block 312 is fixedly connected to the arc-shaped spring piece 313;

[0077] The side of the curved spring 313 closest to the second fixing plate 311 contacts the side wall of the fixing rod 301. When the second fixing plate 311 is worn by the patient and the fixing rod 301 is pushed to slide, the sliding distance of the curved spring 313 and the second fixing plate 311 in the area of ​​the patient's glasses, which is blocked by the glasses rod, is higher than the sliding distance of the other second fixing plates 311.

[0078] A right-angle block 312 is fixedly connected to the end of the fixing rod 301 that is away from the fixing plate 311;

[0079] Among them, the inclined surface of the right-angle block 312 is in contact with the side wall of the wave plate 201, and the end of the fixing plate 311 away from the right-angle block 312 is fixedly connected to the arc-shaped spring piece 313. When the sliding ring 323 pushes the other inclined blocks 321 and the fixing plate 311 to slide on the surface of the fixing rod 301, the sliding of the fixing plate 311 will cause the side wall of the arc-shaped spring piece 313 to separate from the fixing rod 301.

[0080] The limiting component 32 includes two inclined blocks 321 that are fixedly connected to the side of the fixing plate 311 near the right-angle block 312;

[0081] Among them, two rectangular plates 322 are fixedly connected to the side of the fixed plate 311 near the inclined block 321. Several rectangular plates 322 are slidably connected to the outer surface of the outer surface of the rectangular plates 322. When the sliding ring 323 slides, it will press the side wall of the inclined block 321 on the other fixed plate 311. When the inclined block 321 is pressed by the sliding ring 323, it will drive the fixed plate 311 to slide on the surface of the fixed rod 301.

[0082] A method for using a headband-style noise-protective headset, the method comprising the following steps:

[0083] S1: Installing foam: First, fill the inside of the leather case 202 with sound-insulating foam, and then install a sound-insulating pad between the auxiliary ring 212 and the main body 1. The sound-insulating pad can prevent sound leakage between the main body 1 and the auxiliary ring 212 when the user wears it.

[0084] S2: Height Adjustment: The user then adjusts the height between the main body 1 and the adjustment frame 101 according to their own needs;

[0085] S3: Wearing and use: When wearing, the leather cover 202 is placed over the user's ears and made to make close contact with the patient's skin, thereby achieving the purpose of sound insulation for the user when wearing it.

[0086] When in use, first fill the inside of the leather case 202 with sound-insulating sponge, then install a sound-insulating pad between the auxiliary ring 212 and the main body 1. The sound-insulating pad can prevent sound leakage between the main body 1 and the auxiliary ring 212 when the user wears it. Then, the user adjusts the height between the main body 1 and the adjustment frame 101 according to their own needs. Then, when wearing it, cover the user's ears with the leather case 202 and make close contact between the leather case 202 and the patient's skin, thereby achieving the purpose of sound insulation when the user wears it.

[0087] When the user wears the main body 1, the user's skin is compressed against the fixing plate 311 through the leather sleeve 202 and the internal sponge. When the fixing plate 311 is compressed, it will drive the right-angle block 312 to slide through the fixing rod 301. When the right-angle block 312 slides, it will compress the side wall of the wave plate 201 through the inclined surface of its side wall and generate an inclined pushing force on the wave plate 201. When the protruding part of the wave plate 201 is pushed by the right-angle block 312, the wave plate 201 will drive the leather sleeve 202 to rotate through the elastic plate 211 and the auxiliary ring 212. Because the leather sleeve 202 is in close contact with the user's skin, When the auxiliary ring 212 causes the leather case 202 to rotate, the rotation of the leather case 202 will cause the part of the leather case in contact with the user's skin to twist and wrinkle. Through the twisting and surface wrinkling of the leather case 202, the leather case 202 can wrap and fill the eyeglasses around the user's skin, thereby ensuring that the leather case 202 and the internal sound-insulating sponge fit tightly with the patient's skin, reducing the tightness of the seal gap between the leather case 202 and the user's skin. At the same time, it can also improve the isolation effect of the main body 1 through the leather case 202 and the internal sound-insulating sponge to isolate external sound, and improve the isolation efficiency of the headset to isolate external sound.

[0088] When the second fixing plate 311 is worn by the patient and the fixing rod 301 is pushed to slide, the sliding distance of the curved spring piece 313 and the second fixing plate 311 in the area of ​​the patient's glasses, blocked by the glasses rod, is greater than the sliding distance of the other second fixing plates 311. Simultaneously, when the sliding distance of one second fixing plate 311 exceeds the sliding distance of the others, the sliding of one second fixing plate 311 will cause the sliding ring 323 to slide synchronously. Since the sliding distance of the sliding ring 323 also exceeds the sliding distance of the other second fixing plates 311, when the sliding ring 323 slides, it will affect the other second fixing plates 311. The inclined block 321 on 311 is pressed against the side wall. When the inclined block 321 is pressed by the sliding ring 323, it will drive the fixing plate 311 to slide on the surface of the fixing rod 301. When the other fixing plates 311 slide, they can push the leather cover 202 around the eyeglass rod outward, thereby reducing the wrinkles generated by the leather cover 202 in areas other than the eyeglass rod, which would cause excessive pressure or indentation on the user's skin when the leather cover 202 is worn for a long time. This can improve the comfort of the patient when wearing the leather cover 202 for a long time while ensuring that the leather cover 202 fits tightly with the user's skin.

[0089] When the fixing rod 301 measures and pushes the raised area on the surface of the wave plate 201 through the sliding of the right-angle block 312, causing the wave plate 201 to rotate, the rotation of the wave plate 201 will cause the raised part of the wave plate 201 near the fixing block 111 to squeeze the side wall of the fixing block 111. When the raised part of the wave plate 201 is squeezed by the fixing block 111, the wave plate 201 will generate a reverse pushing force on the right-angle block 312 and the fixing rod 301 during the rotation. The reverse pushing force generated on the right-angle block 312 and the fixing rod 301 can improve the tightness of the direct contact between the fixing plate 211 and the patient's skin through the leather sleeve 202. This can reduce the situation where the leather sleeve 202 slides between the user's skin when multiple fixing plates 211 slide outward and push the leather sleeve 202. This can ensure a tight fit between the surface of the leather sleeve 202 and the user's skin, while improving the contact area between the leather sleeve 202 and the user's skin and the sound isolation efficiency when the user wears it.

[0090] When the sliding ring 323 pushes the remaining inclined blocks 321 and the second fixing plate 311 to slide on the surface of the fixing rod 301, the sliding of the second fixing plate 311 will cause the side wall of the arc-shaped spring piece 313 to separate from the fixing rod 301. At this time, the end of the fixing rod 301 away from the right-angle block 312 will slide to the concave area of ​​the arc-shaped spring piece 313. At this time, the arc-shaped spring piece 313 can generate elastic movement between the side walls of the second fixing plate 311. The elastic movement formed by the arc-shaped spring piece 313 on the side wall of the second fixing plate 311 can reduce the excessive wearing pressure and continuous compression of the second fixing plate 311 on the patient when the wave piece 201 pushes the second fixing plate 311 under the obstruction of the fixing block 111, and further improve the patient's comfort when wearing it.
