Description

Technical Field

[0001] The present application belongs to the field of earphone technology, and specifically relates to a headset. Background Art

[0002] Headphones are a device that converts electrical signals into sound signals and are usually used in personal audio playback, communication, and gaming. Headphones include in-ear, semi-in-ear, and head-mounted structures. Compared with in-ear and semi-in-ear headphones, head-mounted headphones have better wrapping around the user's ears and therefore have better noise reduction performance. In addition, headphones are worn on the user's head through a bow-shaped headband, and the headphones do not enter the ears, thereby avoiding the risk of abrasions to the ear canal, while also providing better protection for the eardrum.

[0003] However, the bow-shaped headband of the headset is clamped on the user's head, so that the user will feel a pressure on the head, and wearing it for a long time will cause the user to feel severe pain. Therefore, the wearing comfort of the headset in the related art is poor. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a headset that can solve the technical problem of poor wearing comfort of the headset.

[0005] In order to solve the above technical problems, this application is implemented as follows: The present application discloses a headset, comprising a headset support and a sound unit; The head-mounted bracket includes a bow-shaped headband, a decompression airbag, an air pressure adjustment control and two sliding connectors, the two sliding connectors are respectively sleeved on the two ends of the bow-shaped headband, and both are slidably matched with the bow-shaped headband along the extension direction of the bow-shaped headband; each of the sliding connectors is provided with the sound-generating unit; the decompression airbag is arranged on the inner side of the bow-shaped headband, the decompression airbag has an expansion section and a compression section, the compression section is accommodated in the inner cavity of at least one of the sliding connectors, and the expansion section is located outside the sliding connector; the air pressure adjustment control is arranged on at least one of the bow-shaped headband and the sliding connector, and the air pressure adjustment control is used to inflate or deflate the decompression airbag; When the sliding connector slides in a direction away from the bow-shaped headband, the air pressure regulating control inflates the decompression airbag to increase the length of the expansion section; when the sliding connector slides in a direction toward the bow-shaped headband, the air pressure regulating control deflates the decompression airbag to reduce the length of the expansion section.

[0006] In an embodiment of the present application, a decompression airbag is arranged on the inner side of the bow-shaped headband, and the decompression airbag has an expansion section and a compression section. The compression section is accommodated in the inner cavity of at least one sliding connector, and the expansion section is located outside the sliding connector. An air pressure adjustment control is arranged on at least one of the bow-shaped headband and the sliding connector, and the air pressure adjustment control is used to inflate or deflate the decompression airbag. When the sliding connector slides in a direction away from the bow-shaped headband, the air pressure adjustment control inflates the decompression airbag to increase the length of the expansion section. When the sliding connector slides in a direction toward the bow-shaped headband, the air pressure adjustment control deflates the decompression airbag to reduce the length of the expansion section. In this scheme, a decompression airbag is arranged on the inner side of the bow-shaped headband, and the expansion section of the decompression airbag filled with gas is located outside the sliding connector. At this time, the expansion section of the decompression airbag can fit the user's head. Since the expansion section is filled with gas, the pressure of the bow-shaped headband on the head can be effectively reduced, thereby reducing the user's head pressure feeling, thereby avoiding the user from wearing the headset for a long time to produce a more serious pain. Therefore, compared with the headphones in the related art, the headphones disclosed in the present application are more comfortable to wear. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0009] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0010] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0011] The headset provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0012] Please refer to Figures 1 to 13 The embodiment of the present application discloses a headset, and the disclosed headset includes a head mounted support 100 and a sound unit 200.

[0013] The head-mounted bracket 100 is used to wear the headset on the user's head and is a wearing component of the headset. The sound unit 200 is a specific sound-generating device of the headset, and the sound unit 200 includes but is not limited to components such as a speaker, a speaker housing, and a circuit board.

[0014] The head-mounted bracket 100 includes an arched headband 110, a decompression airbag 120, an air pressure adjustment control 130 and two sliding connectors 140. The two sliding connectors 140 are respectively mounted on both ends of the arched headband 110, and both slide and cooperate with the arched headband 110 along the extension direction of the arched headband 110. Each sliding connector 140 is provided with a sound unit 200. The two sliding connectors 140 here are respectively a first sliding connector 1401 and a second sliding connector 1402, and the first sliding connector 1401 and the second sliding connector 1402 are respectively provided with a sound unit 200, that is, the number of the sound units 200 is also two, and each sound unit 200 is located on the corresponding sliding connector 140.

[0015] The decompression airbag 120 is arranged on the inner side of the bow-shaped headband 110. The decompression airbag 120 has an expansion section 121 and a compression section 122. The compression section 122 is accommodated in the inner cavity of at least one sliding connector 140, and the expansion section 121 is located outside the sliding connector 140. The expansion section 121 here refers to the area of ​​the decompression airbag 120 filled with gas, and the compression section 122 refers to the area of ​​the decompression airbag 120 that is not filled with gas. At this time, the volume of the area of ​​the decompression airbag 120 that is not filled with gas is small, so the compression section 122 can be accommodated in the inner cavity of the sliding connector 140. It can be understood here that the sliding connector 140 is provided with a sliding cavity 1411, and one end of the bow-shaped headband 110 extends into the sliding cavity 1411 from the port of the sliding cavity 1411. At this time, the compression section 122 is accommodated in the gap formed by the inner surface of the bow headband 110 and the inner surface of the sliding cavity 1411 , that is, the bow headband 110 and one of the inner surfaces of the sliding cavity 1411 have a gap to accommodate the compression section 122 .

[0016] The air pressure adjustment control 130 is disposed on at least one of the arch headband 110 and the sliding connection member 140 , and the air pressure adjustment control 130 is used to inflate or deflate the decompression airbag 120 .

[0017] In the specific wearing process, the user needs to slide the sliding connector 140 in a direction away from the bow headband 110 so that the overall length of the sliding connector 140 and the bow headband 110 increases, thereby meeting the wearing needs of the user. In addition, when the sliding connector 140 slides in a direction away from the bow headband 110, the area of ​​the decompression airbag 120 compressed in the inner cavity of the sliding connector 140 gradually extends out of the sliding connector 140, thereby increasing the exposed length of the decompression airbag 120. At this time, if the decompression airbag 120 is not inflated, the exposed area of ​​the decompression airbag 120 cannot reach the expansion state, so the decompression effect cannot be achieved. Therefore, in order to ensure that the overall air pressure of the exposed area is in an expansion state, when the sliding connector 140 slides in a direction away from the bow headband 110, the air pressure adjustment control 130 inflates the decompression airbag 120 to increase the length of the expansion section 121. At this time, the decompression airbag 120 is inflated, so that the exposed area of ​​the decompression airbag 120 increases while the internal air pressure increases, so that the exposed area of ​​the decompression airbag 120 is always in an expanded state, so that the length of the expansion section 121 of the decompression airbag 120 increases, while the length of the compression section 122 decreases. At this time, the length of the expansion section 121 of the decompression airbag 120 can be flexibly adjusted according to specific wearing needs.

[0018] After the headset is used, the user needs to slide the sliding connector 140 in the direction close to the bow headband 110 to shorten the overall length of the sliding connector 140 and the bow headband 110, so as to better store the headset. Since the exposed area of ​​the decompression airbag 120 is filled with gas and difficult to store, when the sliding connector 140 slides in the direction toward the bow headband 110, the air pressure adjustment control 130 deflates the decompression airbag 120, at which time, the air pressure of the expansion section 121 of the decompression airbag 120 decreases, so when the sliding connector 140 slides in the direction close to the bow headband 110, the sliding connector 140 and the bow headband 110 can squeeze the exposed area of ​​the decompression airbag 120 to become the compression section 122 and be stored in the sliding connector 140, so that the length of the expansion section 121 is reduced, and the length of the compression section 122 gradually increases until the sliding connector 140 and the bow headband 110 are reduced to the minimum length position.

[0019] In the embodiment disclosed in the present application, a decompression airbag 120 is provided inside the bow-shaped headband 110, and the expansion section 121 of the decompression airbag 120 filled with gas is located outside the sliding connector 140. At this time, the expansion section 121 of the decompression airbag 120 can fit the user's head. Since the expansion section 121 is filled with gas, the pressure of the bow-shaped headband 110 on the head can be effectively reduced, thereby reducing the user's head pressure feeling, thereby avoiding the user's severe pain caused by wearing the headset for a long time. Therefore, compared with the headset in the related art, the headset disclosed in the present application is more comfortable to wear.

[0020] In addition, the length of the expansion section 121 of the decompression airbag 120 can be specifically adjusted according to the length of the sliding connector 140 and the bow-shaped headband 110, so that the headset fits the wearer's head more closely, thereby facilitating improved wearing firmness and stability. In addition, the length of the expansion section 121 of the decompression airbag 120 can be adaptively inflated and deflated as the sliding connector 140 slides, thus making it more convenient and practical. In addition, the decompression airbag 120 can be flexibly adjusted according to the head size of different users, further improving wearing comfort and stability.

[0021] In addition, the sliding connector 140 in the present application can be slidably connected to the bow-shaped headband 110, so the position between each sound unit 200 and the user's ear can be adjusted. Therefore, the position of the sound source can be adjusted according to the different hearing of the wearer's two ears, preventing the wearer from hearing different sounds in both ears, which is beneficial to improving the sound effect of the headphones.

[0022] In an optional solution, the air pressure adjustment control 130 can be an air pump, which is connected to the decompression airbag 120. Specifically, when the sliding connection 140 slides in a direction away from the bow-shaped headband 110, the air pump inflates the decompression airbag 120. When the sliding connection 140 slides in a direction close to the bow-shaped headband 110, the air pump decompresses the decompression airbag 120.

[0023] In an optional embodiment, at least one of the sliding connectors 140 has an inner cavity provided with an air pressure adjustment control 130, and the air pressure adjustment control 130 may include a connecting rod 131 and a piston 132, one end of the connecting rod 131 is connected to the piston 132, and the end of the connecting rod 131 away from the piston 132 may be connected to the sliding connector 140. The bow-shaped headband 110 is provided with an air charging and discharging space 111 and a pressure-relieving air hole 112, and the piston 132 may be located in the air charging and discharging space 111, and the air charging and discharging space 111 is divided into an air charging chamber 111a and an air discharging chamber 111b arranged along the extension direction of the bow-shaped headband 110. The piston 132 may slide along the extension direction of the bow-shaped headband 110. The decompression airbag 120 has an air charging and discharging air hole 123, the air charging chamber 111a is connected to the air charging and discharging air hole 123, and the pressure-relieving air hole 112 is used to connect the air discharging chamber 111b with the external environment.

[0024] When the sliding connector 140 slides in a direction away from the bow-shaped headband 110, the piston 132 compresses the inflation chamber 111a. At this time, the piston 132 moves toward one side of the inflation chamber 111a, so that the gas in the inflation chamber 111a is pressed into the decompression airbag 120 through the inflation and deflation holes 123 to inflate the decompression airbag 120. When the piston 132 compresses the inflation chamber 111a, the volume of the inflation chamber 111a decreases, while the volume of the deflation chamber 111b increases. At this time, the external air enters the deflation chamber 111b through the equalization air hole 112, so that the pressure in the inflation chamber 111a is the same as that in the deflation chamber 111b.

[0025] When the sliding connector 140 slides in the direction toward the bow-shaped headband 110, the piston 132 compresses the deflation chamber 111b. At this time, the piston 132 moves toward one side of the deflation chamber 111b, so that the gas in the decompression airbag 120 is drawn into the inflation chamber 111a through the inflation and deflation holes 123 to deflate the decompression airbag 120. When the piston 132 compresses the deflation chamber 111b, the volume of the deflation chamber 111b decreases, while the volume of the inflation chamber 111a increases. At this time, the gas in the deflation chamber 111b is pressed out to the external environment through the equalization holes 112, so that the pressure in the inflation chamber 111a is the same as that in the deflation chamber 111b.

[0026] In this solution, the piston 132 slides with the sliding of the sliding connector 140, so that the decompression airbag 120 has better adaptive inflation and deflation performance. In addition, the piston 132 moves in the inflation and deflation space 111 to achieve inflation and deflation operations of the decompression airbag 120, thereby making the structure of the headset simpler.

[0027] In another optional embodiment, a limiting convex portion 111c may be provided on the inner wall of the inflation and discharge space 111, and the limiting convex portion 111c may cooperate with the piston 132 in a sliding direction of the sliding connection member 140 away from the bow-shaped headband 110. In the extension direction of the bow-shaped headband 110, the piston 132 and the inflation and discharge holes 123 may be located on both sides of the limiting convex portion 111c, and the pressure-equalizing holes 112 may be located on both sides of the piston 132 with the limiting convex portion 111c. In this solution, in the extension direction of the bow-shaped headband 110, the limiting convex portion 111c may cooperate with the piston 132 in a limiting manner along the sliding connection member 140, thereby avoiding the risk of the piston 132 falling out of the inflation and discharge space 111, thereby improving the reliability of the headset.

[0028] In the above solution, the number of the decompression airbag 120 may be one, and both ends of the decompression airbag 120 may be accommodated in two sliding connectors 140 .

[0029] In another optional solution, the number of the decompression airbags 120 is at least two, namely, the first decompression airbag 1201 and the second decompression airbag 1202. The first decompression airbag 1201 and the second decompression airbag 1202 are both arranged on the inner side of the arched headband 110 and are arranged at intervals along the extension direction of the arched headband 110. The compression section 122 of the first decompression airbag 1201 can be accommodated in the inner cavity of the first sliding connector 1401, and the compression section 122 of the second decompression airbag 1202 is accommodated in the inner cavity of the second sliding connector 1402.

[0030] The number of air pressure adjusting controls 130 can be at least two, namely a first air pressure adjusting control 1301 and a second air pressure adjusting control 1302. The first air pressure adjusting control 1301 can be arranged on at least one of the bow-shaped headband 110 and the first sliding connector 1401, and the first air pressure adjusting control 1301 is used to inflate or deflate the first decompression airbag 1201; the second air pressure adjusting control 1302 is arranged on at least one of the bow-shaped headband 110 and the second sliding connector 1402, and the second air pressure adjusting control 1302 is used to inflate or deflate the second decompression airbag 1202.

[0031] When the first sliding connector 1401 slides in a direction away from the bow-shaped headband 110, the first air pressure regulating control 1301 inflates the first decompression airbag 1201 to increase the length of the expansion section 121 of the first decompression airbag 1201; when the first sliding connector 1401 slides in a direction toward the bow-shaped headband 110, the first air pressure regulating control 1301 deflates the first decompression airbag 1201 to reduce the length of the expansion section 121 of the first decompression airbag 1201.

[0032] When the second sliding connector 1402 slides in a direction away from the bow-shaped headband 110, the second air pressure regulating control 1302 inflates the second decompression airbag 1202 to increase the length of the expansion section 121 of the second decompression airbag 1202; when the second sliding connector 1402 slides in a direction toward the bow-shaped headband 110, the second air pressure regulating control 1302 deflates the second decompression airbag 1202 to reduce the length of the expansion section 121 of the second decompression airbag 1202.

[0033] In this solution, the first decompression airbag 1201 and the second decompression airbag 1202 can be adjusted separately, thereby further improving the user's adjustment flexibility and further improving the user's wearing comfort.

[0034] The first air pressure adjustment control 1301 and the second air pressure adjustment control 1302 can both be air pumps. Alternatively, the first air pressure adjustment control 1301 and the second air pressure adjustment control 1302 can both be the above-mentioned connecting rod 131 and piston 132, and the bow-shaped headband 110 is provided with two independent air filling and deflation spaces 111, and each air filling space cooperates with a piston 132, so as to realize the inflation and deflation operation of a corresponding decompression airbag 120.

[0035] Furthermore, the bow headband 110 may include a first arc segment 1101, a second arc segment 1102 and an angle adjustment mechanism 1103, and the first arc segment 1101 and the second arc segment 1102 may be movably connected via the angle adjustment mechanism 1103. The angle adjustment mechanism 1103 may be used to adjust the angle between the first arc segment 1101 and the second arc segment 1102.

[0036] The first sliding connection member 1401 can be sleeved on one end of the first arc segment 1101 away from the second arc segment 1102. The second sliding connection member 1402 can be sleeved on one end of the second arc segment 1102 away from the first arc segment 1101. The first decompression airbag 1201 can be arranged on the inner side of the first arc segment 1101, and the second decompression airbag 1202 can be arranged on the inner side of the second arc segment 1102.

[0037] In this solution, the bow-shaped headband 110 is composed of two independent arc segments, and the two independent arc segments can be adjusted in angle through the angle adjustment mechanism 1103, so the clamping force of the bow-shaped headband 110 on the user's head can be adjusted, thereby further improving the wearing comfort performance.

[0038] In an optional solution, the angle adjustment mechanism 1103 may be a rotating shaft, and the first arc segment 1101 and the second arc segment 1102 may be rotatably connected via the rotating shaft.

[0039] Alternatively, in another optional solution, the angle adjustment mechanism 1103 may be a hinge, a hinge, a flexible wire or other components.

[0040] In another optional embodiment, the angle adjustment mechanism 1103 may include a first hinge seat 11031, a second hinge seat 11032, a first rotation shaft 11033, a second rotation shaft 11034, an adjustment sleeve 11035 and an adjustment screw 11036. The first hinge seat 11031 may be fixed to the first arc segment 1101, and the second hinge seat 11032 may be fixed to the second arc segment 1102. The first rotation shaft 11033 may be rotatably connected to the first hinge seat 11031, and the second rotation shaft 11034 may be rotatably connected to the second hinge seat 11032, and the first rotation shaft 11033 and the second rotation shaft 11034 are parallel. The axis of the adjusting sleeve 11035 is perpendicular to the axis of the first rotating shaft 11033. The adjusting sleeve 11035 is rotatably connected relative to the first rotating shaft 11033 around its central axis. The adjusting screw 11036 is fixedly connected to the second rotating shaft 11034. The adjusting sleeve 11035 is sleeved on the adjusting screw 11036. The adjusting sleeve 11035 is threadedly connected to the adjusting screw 11036.

[0041] In the specific adjustment process, the angle adjustment of the first arc segment 1101 and the second arc segment 1102 can be achieved through the first rotating shaft 11033 and the second rotating shaft 11034. By rotating the adjusting sleeve 11035, the overall length of the sleeve 11035 and the adjusting screw 11036 can be adjusted, thereby achieving the distance adjustment between the first arc segment 1101 and the second arc segment 1102.

[0042] This solution can adjust the angle of the first arc segment 1101 and the second arc segment 1102, and can also adjust the distance between the first arc segment 1101 and the second arc segment 1102, so that the clamping force of the bow headband 110 on the user's head can be accurately adjusted, making the headset more comfortable to wear.

[0043] In another optional embodiment, the angle adjustment mechanism 1103 may further include a rotating ring 11037, which is sleeved on the outer circumference of the adjustment sleeve 11035, and the rotating ring 11037 can drive the adjustment sleeve 11035 to rotate. In this case, the design of the rotating ring 11037 makes it more convenient for the user to rotate the adjustment sleeve 11035, thereby facilitating the adjustment of the distance between the first arc segment 1101 and the second arc segment 1102.

[0044] In the above embodiment, the sliding connector 140 is provided with a receiving groove 1421, at least part of the sound unit 200 is located in the receiving groove 1421, and the sound output side of the sound unit 200 faces the notch of the receiving groove 1421. At this time, the position of the sound unit 200 on the sliding connector 140 is fixed. Under normal circumstances, the hearing of the two ears of the user is different, so the position of the sound unit 200 is fixed, which easily leads to inconsistent sound volume heard by the two ears of the user, thereby making the sound experience of the headset poor.

[0045] Based on this, in another optional solution, the headset may further include a driver 300, which may be disposed on the sliding connector 140, and the driver 300 may be connected to the sound unit 200. The driver 300 may be used to drive the sound unit 200 to move in the direction toward or away from the notch of the accommodating groove 1421. At this time, the closer the sound unit 200 is to the notch of the accommodating groove 1421, the closer the distance between the sound unit 200 and the ear is, and the louder the sound heard by the user. Conversely, the farther the sound unit 200 is from the notch of the accommodating groove 1421, the farther the distance between the sound unit 200 and the ear is, and the smaller the sound heard by the user. In this solution, the position of the sound unit 200 is adjusted by the driver 300, so that the position of the sound unit 200 can be adjusted according to the difference in binaural hearing, so that the sound heard by the user's binaural ears is consistent, further improving the sound experience of the headset.

[0046] Optionally, the driving member 300 may be a linear motor, and a driving end of the linear motor may be connected to the sound generating unit 200. Alternatively, the driving member 300 may be a power structure composed of a motor and a transmission member.

[0047] In another optional embodiment, the driving member 300 may include an operating knob 310 and a driving screw 320. The operating knob 310 may be disposed on the outer side of the sliding connection member 140 and may rotate relative to the sliding connection member 140. A through hole communicating with the accommodating groove 1421 is provided at the bottom of the accommodating groove 1421. One end of the driving screw 320 extends out of the accommodating groove 1421 through the through hole and is fixedly connected to the operating knob 310. The other end of the driving screw 320 is threadedly connected to the sound unit 200. The inner side wall of the accommodating groove 1421 may be provided with a first limiting portion 1421a, and the sound unit 200 is provided with a second limiting portion 201. The sound unit 200 and the sliding connection member 140 are limited along the circumferential direction of the accommodating groove 1421 through the first limiting portion 1421a and the second limiting portion 201.

[0048] In the specific adjustment process, when the operating knob 310 rotates along the first rotation direction, the operating knob 310 drives the driving screw 320 to rotate, and the thread of the driving screw 320 applies a rotational component force and a force in the direction of the notch of the receiving groove to the thread on the sound unit 200. Due to the limiting cooperation between the first limiting portion 1421a and the second limiting portion 201, the rotational component force can be balanced, so that the sound unit 200 is only subjected to the force in the direction of the notch of the receiving groove, thereby driving the sound unit 200 to move in the direction of the notch of the receiving groove. Similarly, when the operating knob 310 rotates in a second rotation direction opposite to the first rotation direction, the operating knob 310 drives the driving screw 320 to rotate, and the thread of the driving screw 320 applies a rotational component force and a force toward the bottom direction of the accommodating groove 1421 to the thread on the sound unit 200. Since the first limiting portion 1421a and the second limiting portion 201 are limited and matched, the rotational component force can be balanced, so that the sound unit 200 is only subjected to the force toward the bottom direction of the accommodating groove, thereby driving the sound unit 200 to move in the direction toward the bottom direction of the accommodating groove 1421.

[0049] In this solution, the driving member 300 is manually driven, so the structure is simple, and the power loss of the headset is also reduced, which is beneficial to improving the battery life performance of the headset.

[0050] Further, the sound unit 200 may include a unit body 210 and an annular convex portion 220, the annular convex portion 220 may be arranged on the outer peripheral surface of the unit body 210, and the driving screw 320 may be threadedly connected to the unit body 210. The inner side wall of the accommodating groove 1421 may be provided with an annular recess 1422 extending along its circumference, the annular recess 1422 having a first limiting surface 1422a and a second limiting surface 1422b arranged oppositely, and the annular convex portion 220 may be located between the first limiting surface 1422a and the second limiting surface 1422b. At this time, the annular convex portion 220 may be limitedly matched with the first limiting surface 1422a in the direction from the notch of the accommodating groove 1421 to the bottom of the groove. When the annular recess 1422 penetrates to the bottom position of the groove toward one side of the bottom of the accommodating groove 1421, the first limiting surface 1422a is a partial area of ​​the bottom of the groove. The annular protrusion 220 can be limitedly matched with the second limiting surface 1422b in the direction from the bottom of the accommodating groove 1421 to its groove opening.

[0051] In this solution, the annular protrusion 220 is located in the annular recess 1422, so the annular recess 1422 can limit the movement distance of the annular protrusion 220, thereby avoiding the risk of over-adjustment of the sound unit 200, and further improving the safety performance of the adjustment of the sound unit 200.

[0052] In an optional solution, one of the first limiting portion 1421a and the second limiting portion 201 is a protrusion, and the other is a groove.

[0053] In another optional embodiment, the first limiting portion 1421a may be a strip-shaped convex portion, the second limiting portion 201 may be a limiting notch, at least part of the strip-shaped convex portion is located in the limiting notch, the strip-shaped convex portion may be arranged on the inner side wall of the annular recess 1422, and the limiting notch may be provided on the annular convex portion 220. This solution has a simple structure, and is therefore conducive to reducing the manufacturing cost of the headset.

[0054] In one solution, a limiting bracket 143 may be provided on the outer surface of the sliding connector 140, and the limiting bracket 143 may form a limiting space 143a with the outer surface of the sliding connector 140, and a portion of the operating knob 310 may be located in the limiting space 143a, and the operating knob 310 may be limitedly matched with the limiting bracket 143 in a direction from the notch of the accommodating groove 1421 to the bottom of the groove. This solution can prevent the operating knob 310 from being separated from the sliding connector 140, thereby improving the safety and reliability of the headset.

[0055] In order to avoid the risk of the position of the sound unit 200 changing due to accidental rotation of the operating knob 310, in an optional embodiment, a mounting groove 311 is provided on the side of the operating knob 310 facing the limiting bracket 143, and the driving member 300 may further include an elastic limiting member 330, a portion of the elastic limiting member 330 may be located in the mounting groove 311, one end of the elastic limiting member 330 may abut against the limiting bracket 143, one end of the elastic limiting member 330 may abut against the bottom of the mounting groove 311, and the elastic limiting member 330 is compressed and arranged between the limiting bracket 143 and the operating knob 310.

[0056] In a specific operation process, when adjusting the sound unit 200, the rotational force applied by the user to the operating knob 310 needs to be greater than the pressure of the elastic driving member 300 on the operating knob 310, so that the operating knob 310 rotates. When the adjustment is completed, the pressure of the elastic driving member 300 on the operating knob 310 can lock the operating knob 310, thereby avoiding the risk of accidental rotation of the operating knob 310.

[0057] This solution can lock the operating knob 310, thereby avoiding the risk of accidental rotation of the operating knob 310, and thus allowing the sound unit 200 to remain in the current position.

[0058] Furthermore, the elastic limiting member 330 may include a limiting pressure plate 331, a limiting sleeve 332 and an elastic member 333. The limiting pressure plate 331 may abut against the bottom of the mounting groove 311. The limiting pressure plate 331 may rotate around its center axis relative to the operating knob 310. The elastic member 333 is arranged on the side of the limiting pressure plate 331 away from the bottom of the mounting groove 311. One end of the elastic member 333 can be connected to the limiting pressure plate 331, and one end of the limiting sleeve 332 can be fixedly connected to the limiting pressure plate 331. The limiting sleeve 332 is sleeved on the elastic member 333. A connecting protrusion 1431 is provided on the surface of the limiting bracket 143 facing the operating knob 310. The connecting protrusion 1431 is sleeved outside the limiting sleeve 332 and fixedly connected to the limiting sleeve 332. One end of the elastic member 333 facing away from the limiting pressure plate 331 is connected to the limiting bracket 143, and the elastic member 333 is compressed and arranged between the limiting bracket 143 and the limiting pressure plate 331.

[0059] This solution can help increase the friction between the elastic limiter 330 and the operating knob 310 bracket, thereby further avoiding the risk of accidental rotation of the operating knob 310.

[0060] Optionally, the limiting sleeve 332 and the connecting protrusion 1431 can be connected by bonding or clamping. Of course, the limiting sleeve 332 and the connecting protrusion 1431 can also be connected by interference fit. Alternatively, the outer surface of the limiting sleeve 332 can be a square structure, and the inner hole of the connecting protrusion 1431 can also be a square hole. The square outer surface matches the square hole, so that the limiting sleeve 332 and the connecting protrusion 1431 are connected.

[0061] In another optional solution, the sliding connector 140 may include a strip sliding portion 141 and a mounting seat 142, and the strip sliding portion 141 may be provided with the above-mentioned sliding cavity 1411. One end of the bow-shaped headband 110 may be slidably located in the sliding cavity 1411. The above-mentioned compression section 122 may be accommodated in the sliding cavity 1411 of at least one strip sliding portion 141. The mounting seat 142 may be fixedly connected to one end of the strip sliding portion 141 away from the bow-shaped headband 110, and the mounting seat 142 may be provided with a receiving groove 1421, and the above-mentioned driving member 300 may be arranged on the mounting seat 142. In this solution, the sliding connector 140 has the strip sliding portion 141, so that the adjustment range of the sliding connector 140 and the bow-shaped headband 110 can be further increased.

[0062] Furthermore, the sliding connector 140 may further include a noise reduction sponge cover 144 and a noise reduction liner 145. The noise reduction sponge cover 144 is connected to the mounting seat 142 and is arranged around the notch of the accommodating groove 1421. The noise reduction liner 145 may be embedded in the mounting seat 142 and arranged around the accommodating groove 1421.

[0063] In this solution, the noise reduction sponge cover 144 and the noise reduction liner 145 can further improve the noise reduction performance of the headphone.
