Description

Technical Field

[0001] The present invention relates to the technical field of near-ear audio, and specifically to a high-compliance near-ear audio and a high-sensitivity sound broadcasting device. Background Art

[0002] Near-ear audio is different from in-ear audio. When in use, it does not need to be inserted deep into the ear canal, and the sound-emitting unit covers the auricle. Compared with in-ear audio, near-ear audio can avoid scratching the ear canal, has better comfort, and can be worn for a relatively longer time.

[0003] Near-ear audio usually consists of earcups, a headband, and telescopic rods. The telescopic rods are used to adjust the length of the headband, thereby changing the tightness of the headphones. According to the size of the individual's head shape, gradually adjust the length of the telescopic rods. If the head shape is larger, the telescopic rods can be stretched outwards; if the head shape is smaller, the telescopic rods can be retracted inwards. Pay attention to keeping the lengths of the two telescopic rods the same to ensure balance during wearing.

[0004] After the size adjustment of the existing near-ear audio is completed, it is usually simply locked through damping. With long-term use, damping failure may occur, and during the adjustment process, it is impossible to synchronously control the telescopic amounts of the two telescopic rods to always be the same, which will result in the two earcups being in an asymmetric position, leading to subsequent problems such as wearing deviation and looseness. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-compliance near-ear audio and a high-sensitivity sound broadcasting device to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A high-compliance near-ear audio, comprising: a fitting plate, and elastic brackets that are symmetrically arranged and slidably installed in the fitting plate. The ends of the elastic brackets are hinged with connecting rods, and a sound broadcaster is fixed on the connecting rods; further comprising: a spacing control mechanism, which is arranged in the fitting plate and connected to the elastic brackets, and the spacing control mechanism can adjust the spacing between the two sound broadcasters through the elastic brackets and the connecting rods; a follow-up bending assembly, which is arranged on the fitting plate and connected to the elastic brackets, and the follow-up bending assembly can act when the spacing control mechanism moves to adjust the bending angle of the elastic brackets; a locking mechanism, which is arranged in the fitting plate and connected to the spacing control mechanism, and an unlocking mechanism connected to the locking mechanism is also arranged in the fitting plate. The unlocking mechanism can perform locking or unlocking actions on the spacing control mechanism through the locking mechanism.

[0007] As a further solution of the present invention: the spacing adjustment mechanism includes a sliding groove opened on the side wall of the sleeve plate, a sliding block is slidably installed in the sliding groove, an arc-shaped limit plate placed in the sleeve plate is fixed to the side wall of the sliding block, and a guide component connected to the elastic bracket is arranged on the arc-shaped limit plate.

[0008] As a further solution of the present invention: the guide assembly includes corrugated grooves that are opened on the arc-shaped limit plate and are symmetrically arranged, and a limit block is fixed on the elastic bracket, and the limit block is slidably engaged with the corrugated groove.

[0009] As a further solution of the present invention: the follower bending assembly includes an arc-shaped support sleeve fixedly installed on the outside of the sleeve plate and symmetrically arranged, an arc-shaped support plate is slidably installed in the arc-shaped support sleeve, and a hinge rod hinged to the elastic bracket is fixed at the end of the arc-shaped support plate.

[0010] As a further solution of the present invention: the locking mechanism includes a fixed sleeve fixedly installed in the sleeve plate and symmetrically arranged, a movable rod is slidably installed in the fixed sleeve, springs are sleeved on the fixed sleeve and the movable rod, and a limiting assembly connected to the sliding block is provided on the movable rod.

[0011] As a further solution of the present invention: the limiting assembly includes fixed teeth fixedly installed on both sides of the sliding block, a follower plate is fixed to the end of the movable rod, the follower plate is in contact with the spring, and a follower tooth engaged with the fixed teeth is fixed on the follower plate.

[0012] As a further solution of the present invention: the unlocking mechanism includes a through groove opened on the sleeve plate, a limiting sleeve is fixed on the sliding block, a push rod slidably installed in the limiting sleeve and slidably connected to the through groove, a push ring is fixed at one end of the push rod facing away from the limiting sleeve, and a pushing assembly connected to the push rod is provided on the limiting sleeve.

[0013] As a further solution of the present invention: the pushing component includes a slot opened on the circumferential outer wall of the limiting sleeve, a movable plate slidably connected to the slot is fixed on the push rod, and symmetrically arranged inclined blocks are fixed on the movable plate, and the inclined blocks are in contact with the follower plate.

[0014] A high-sensitivity audio broadcasting device comprises the highly adaptable near-ear audio system.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This application can, through the cooperation of the locking mechanism and the unlocking mechanism, adjust the distance between the two players, and after the adjustment is completed, automatically lock the position of the speaker. Specifically, in the initial state, under the action of the locking mechanism, the elastic bracket is controlled by the distance adjustment mechanism to be in a locked state. If the user's head circumference does not match the size of the speaker, it is necessary to adjust the distance between the two speakers. At this time, the unlocking mechanism can be manually controlled to move, driving the locking mechanism to move, so that the locking mechanism no longer locks the distance adjustment mechanism. At this time, the size of the mutual nesting of the elastic bracket and the nesting plate can be freely adjusted, and under the action of the distance adjustment mechanism, it can also ensure that the movement strokes of the two elastic brackets always remain the same, so as to ensure that the distances between the two speakers and the nesting plate are the same when adjusting. When the adjustment is completed, the force applied to the unlocking mechanism is removed, and the locking mechanism automatically resets. Under the action of the locking mechanism, the elastic bracket is locked again through the distance adjustment mechanism.

[0016] When the elastic bracket moves, it can also drive the follower bending assembly to move. Under the action of the follower bending assembly, the bending angle of the end of the elastic bracket can be automatically adjusted according to the extension amount of the elastic bracket, so as to ensure that the speaker can always fit on the user's ear, so that this audio will not become loose and fall off the user's head.

[0017] By controlling the cooperation state of the limit teeth and the fixed teeth, the adjustment and locking of the elastic bracket can be realized, making this audio have the advantages of simple use and convenient operation. If this audio, during use, due to misoperation or other factors, suddenly applies a large force to the speaker or the elastic bracket, since the follower plate is subjected to the thrust provided by the spring, therefore, when the force received by the sliding block is greater than the locking force provided by the limit teeth and the fixed teeth, under the action of the spring, the follower plate will give way to prevent the problem that when the locking force provided to the elastic bracket conflicts with the excessive external force received, the elastic bracket is damaged.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] In addition, the elements in the present invention are referred to as "fixed to" or "disposed on" another element, which can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0032] Please refer to Figures 1 to 11 , in an embodiment of the present invention, a high-conformity near-ear sound device includes: a fitting plate 1, and elastic brackets 2 that are slidably installed in the fitting plate 1 and are symmetrically arranged. A connecting rod 3 is hinged to the end of the elastic bracket 2, and a speaker 4 is fixed on the connecting rod 3; it further includes: a spacing adjustment mechanism, which is arranged in the fitting plate 1 and is connected to the elastic bracket 2, and the spacing adjustment mechanism can adjust the spacing between the two speakers 4 through the elastic bracket 2 and the connecting rod 3; a follow-up bending assembly, which is arranged on the fitting plate 1 and is connected to the elastic bracket 2, and the follow-up bending assembly can act when the spacing adjustment mechanism moves to adjust the bending angle of the elastic bracket 2; a locking mechanism, which is arranged in the fitting plate 1 and is connected to the spacing adjustment mechanism, and an unlocking mechanism connected to the locking mechanism is further arranged in the fitting plate 1, and the unlocking mechanism can perform a locking or unlocking action on the spacing adjustment mechanism through the locking mechanism.

[0033] Specifically, when using this sound device, the fitting size of the two elastic brackets 2 and the fitting plate 1 can be adjusted according to the user's head circumference, so as to adjust the spacing between the two speakers 4. At this time, the unlocking mechanism can be manually controlled to move, and the spacing adjustment mechanism can be unlocked through the locking mechanism, so that the two elastic brackets 2 can freely slide in the fitting plate 1. At this time, the two elastic brackets 2 can be controlled to move in the direction of approaching or separating from each other, and under the action of the spacing adjustment mechanism, the moving sizes of the two elastic brackets 2 in the fitting plate 1 are the same, so as to ensure that the distances between the two speakers 4 and the fitting plate 1 are the same. When the elastic bracket 2 moves, it will also drive the follow-up bending assembly to move. Under the action of the follow-up bending assembly, when the spacing between the two speakers 4 increases, the bending angle of the elastic bracket 2 can be controlled to increase, or when the spacing between the two speakers 4 decreases, the bending angle of the elastic bracket 2 can be controlled to decrease, so as to ensure that the two speakers 4 fit better with the user's ears, thereby ensuring that this sound device can be adapted to different users.

[0034] Please refer to Figures 3 to 5 、 Figure 7 、 Figure 11, the spacing adjustment mechanism includes a chute 9 opened on the side wall of the fitting plate 1. A slidable block 12 that can slide up and down is slidably installed in the chute 9. An arc-shaped limiting plate 11 placed inside the fitting plate 1 is fixed on the side wall of the slidable block 12. A guiding component connected to the elastic bracket 2 is arranged on the arc-shaped limiting plate 11. Among them, the guiding component includes corrugated grooves 1101 that are symmetrically arranged on the side surface of the arc-shaped limiting plate 11. A limiting block 8 is fixed on the side surface of the elastic bracket 2, and the limiting block 8 is slidably fitted with the corrugated grooves 1101.

[0035] Specifically, the corrugated groove 1101 is composed of two symmetrically arranged inclined grooves repeated in combination, and multiple groups of inclined grooves are arranged along the arc track of the arc-shaped limiting plate 11. In the initial state, the two limiting blocks 8 are respectively located at the end of the stroke of the mutually approaching ends of the two corrugated grooves 1101, so that the size of the two elastic brackets 2 sleeved into the fitting plate 1 is the largest, so as to control the minimum distance between the two speakers 4 through the connecting rod 3. When it is necessary to increase the distance between the two speakers 4, under the action of the unlocking mechanism, the restriction on the slidable block 12 is released through the locking mechanism, so that the slidable block 12 can freely slide along the chute 9. At this time, any one or both of the elastic brackets 2 can be manually driven to move in the direction away from each other, thereby driving the limiting block 8 to slide in the corrugated groove 1101. Due to the limitation of the inclination direction of the corrugated groove 1101, the elastic bracket 2 drives the arc-shaped limiting plate 11 to move up and down while moving away from each other, and then drives the slidable block 12 to move along the length direction of the chute 9. Since the corrugated grooves 1101 are symmetrically arranged, the positions of the two limiting blocks 8 in the two corrugated grooves 1101 are the same, ensuring that the sizes of the two elastic brackets 2 sleeved with the fitting plate 1 always remain the same, so as to ensure that the distances between the speakers 4 and the center position of the fitting plate 1 are the same. When the user wears it, it can ensure that the speakers 4 are in contact with the user's ears.

[0036] Preferably, after the elastic bracket 2 is adjusted to the required position, under the action of the locking mechanism, the position of the slidable block 12 in the chute 9 will not change. Under the action of the corrugated groove 1101 and the limiting block 8, the position of the elastic bracket 2 is locked to ensure that the sound box will not loosen during use. Among them, the fitting plate 1 is made of a hard material, and a protective sleeve is wrapped on its outer surface. The protective sleeve is made of a soft material, which can increase the comfort of the user and prevent the problem of head discomfort caused by the fitting plate 1 fitting with the user's head.

[0037] Please refer to Figures 1 to 3 、 Figure 5 、 Figure 10, the follower bending assembly includes arc-shaped support sleeves 5 fixedly installed on the outer side of the fitting plate 1 and arranged symmetrically. An arc-shaped support plate 6 is slidably installed in the arc-shaped support sleeve 5, and a hinge rod 7 hinged to the elastic bracket 2 is fixed at the end of the arc-shaped support plate 6.

[0038] It should be noted that the elastic bracket 2 can undergo elastic deformation to a certain extent. The arc-shaped support sleeve 5 is arranged in an arc shape, and the fitting plate 1 is also arranged in an arc shape. With the center of the fitting plate 1 as the center point, the center of the arc-shaped support sleeve 5 is located at a position offset from the center point towards the fitting plate 1, and the circumferential radius of the arc-shaped support sleeve 5 is smaller than the circumferential radius of the arc-shaped support sleeve 5. Therefore, with the central axis of the fitting plate 1 as the reference, the angle between the arc-shaped support sleeve 5 with the same arc length and the central axis is smaller than the angle between the fitting plate 1 with the same arc length and the central axis. In the initial state, the size of the mutual fitting between the elastic bracket 2 and the fitting plate 1 is the largest. Under the action of the hinge rod 7, the size of the mutual fitting between the arc-shaped support plate 6 and the arc-shaped support sleeve 5 is the largest. When it is necessary to increase the spacing of the speakers 4, at this time, control the two elastic brackets 2 to move in the direction away from each other, and drive the hinge rod 7 to move, so that the arc-shaped support plate 6 moves in the direction away from the arc-shaped support sleeve 5. Since the arc-shaped support plate 6 will continuously deviate towards the direction of the elastic bracket 2 during movement, under the action of the hinge rod 7, the ends of the two elastic brackets 2 close to the speakers 4 continuously swing towards each other. When the adjustment is completed, under the action of the locking mechanism, the position of the elastic bracket 2 no longer changes.

[0039] Preferably, when it is necessary to increase the spacing between the two speakers 4, through the cooperation of the arc-shaped support plate 6 and the hinge rod 7, the elastic bracket 2 can be controlled to gradually swing towards the central axis direction of the fitting plate 1, so as to ensure that the speakers 4 can always fit on the user's ears. Among them, the fixing method of the arc-shaped support sleeve 5 is to be sleeved on a rotating shaft, and this rotating shaft is fixed to the fitting plate 1 by bolts. During normal use, the bolts can be used to fix the rotating shaft, so that the angle of the arc-shaped support sleeve 5 will not change. The initial angle of the arc-shaped support sleeve 5 can also be adjusted by loosening the bolts, so as to adjust the included angle between the arc-shaped support sleeve 5 and the fitting plate 1 in the initial state, so as to change the deformation amount at the end of the elastic bracket 2 when adjusting the size of the elastic bracket 2 according to actual needs, thereby further increasing the applicable range of this audio.

[0040] Please refer to Figure 2 、 Figures 5 to 9 、 Figure 11, the locking mechanism includes fixed sleeves 14 that are fixedly installed symmetrically inside the fitting plate 1. An active rod 15 is slidably installed inside the fixed sleeves 14. A spring 16 is sleeved on the fixed sleeves 14 and the active rod 15. A limiting component connected to the sliding block 12 is arranged on the active rod 15. Among them, the limiting component includes fixed teeth 13 fixedly installed on both sides of the sliding block 12. A follower plate 17 is fixed to the end of the active rod 15. The follower plate 17 abuts against the spring 16. A limiting tooth 18 that engages with the fixed teeth 13 is fixed to the follower plate 17.

[0041] Furthermore, the side of the follower plate 17 away from the arc-shaped limiting plate 11 is arranged in a right trapezoid shape, and the inclined surface of the right trapezoid part cooperates with the unlocking mechanism. In the initial state, the unlocking mechanism is not subjected to an external force, and the spring 16 is in a compressed state, so that the follower plate 17 is located at the end of the stroke in the direction away from the fixed sleeve 14. Under the action of the follower plate 17, the limiting tooth 18 and the fixed teeth 13 are controlled to be in an engaged state, so as to lock the position of the sliding block 12 through the limiting tooth 18 and the fixed teeth 13. When it is necessary to adjust the distance between the two speakers 4, at this time, the unlocking mechanism can be manually controlled to move. Under the action of the unlocking mechanism, the follower plate 17 is driven to move, so as to drive the active rod 15 to move towards the fixed sleeve 14, so that the spring 16 is compressed. The follower plate 17 will also drive the limiting tooth 18 to move in the direction away from the fixed teeth 13. When the limiting tooth 18 is separated from the fixed teeth 13, the sliding block 12 can move freely. At this time, the elastic support 2 can be controlled to slide in the fitting plate 1 to adjust the distance between the two speakers 4. After the adjustment is completed, the force applied to the unlocking mechanism is removed. At this time, the spring 16 elastically releases and drives the follower plate 17 to move towards the sliding block 12 to drive the active rod 15 to move in the direction away from the fixed sleeve 14. At the same time, the follower plate 17 will also drive the limiting tooth 18 to move. When the limiting tooth 18 is engaged with the fixed teeth 13 again, the position of the sliding block 12 is locked again.

[0042] Preferably, by controlling the cooperation state of the limiting tooth 18 and the fixed teeth 13, the adjustment and locking of the elastic support 2 can be realized, so that the sound box has the advantages of simple use and convenient operation. If the sound box is used and a large force is suddenly applied to the speaker 4 or the elastic support 2 due to misoperation or other factors, since the follower plate 17 receives the thrust provided by the spring 16, when the force received by the sliding block 12 is greater than the locking force provided by the limiting tooth 18 and the fixed teeth 13, under the action of the spring 16, the follower plate 17 will give way to prevent the problem that the elastic support 2 is damaged when the locking force provided to the elastic support 2 conflicts with the excessive external force received.

[0043] Please refer toFigure 2 , Figures 5 to 9 , Figure 11 , the unlocking mechanism includes a through groove 10 formed in the fitting plate 1. A limiting sleeve 19 is fixed on the sliding block 12. A push rod 21 that is slidably connected to the through groove 10 is slidably installed in the limiting sleeve 19. One end of the push rod 21 away from the limiting sleeve 19 is fixed with a pushing ring 22. A pushing assembly connected to the push rod 21 is arranged on the limiting sleeve 19. Wherein, the pushing assembly includes a clamping groove 20 formed on the circumferential outer wall of the limiting sleeve 19. An activity plate 23 slidably connected to the clamping groove 20 is fixed on the push rod 21. Symmetrically arranged inclined blocks 24 are fixed on the activity plate 23. The inclined blocks 24 are in abutting cooperation with the follower plate 17.

[0044] Furthermore, the inclined blocks 24 are arranged in an inclined shape, and the inclined surfaces are in abutting cooperation with the inclined surfaces of the follower plate 17. In the initial state, under the action of the spring 16, the distance between the two follower plates 17 is minimized, and the limit teeth 18 and the fixed teeth 13 are in a clamped state. Under the action of the inclined surface of the follower plate 17, the inclined blocks 24 are located at the end of the stroke in the direction away from the sliding block 12, so that the activity plate 23 is located at the end of the stroke on the side of the clamping groove 20 away from the sliding block 12. When it is necessary to adjust the distance between the speakers 4, at this time, the pushing ring 22 can be manually controlled to move towards the fitting plate 1, and the push rod 21 is driven to move into the limiting sleeve 19, thereby driving the activity plate 23 to move along the length direction of the clamping groove 20. The activity plate 23 will also drive the inclined blocks 24 to move. When the inclined surface of the inclined block 24 abuts against the inclined surface of the follower plate 17, the follower plate 17 is driven to move in the direction away from the sliding block 12, so that the limit teeth 18 and the fixed teeth 13 are separated, ensuring that the sliding block 12 can slide freely. At this time, the fitting size of the elastic bracket 2 and the fitting plate 1 can be adjusted. When the adjustment of the elastic bracket 2 is completed, the distance between the two speakers 4 is adapted to the head circumference of the user. At this time, the spring 16 elastically releases and drives the follower plate 17 to move towards the sliding block 12, so as to drive the limit teeth 18 to move to the position where they are engaged with the fixed teeth 13 again. Under the action of the inclined surface of the follower plate 17 and the inclined block 24, the activity plate 23 and the push rod 21 are reset.

[0045] Preferably, by pressing the pushing ring 22, the unlocking of the elastic bracket 2 can be realized. At the same time, after the adjustment is completed, only the force applied to the pushing ring 22 needs to be removed. Under the action of the spring 16, the automatic reset of the pushing ring 22 can also be realized, and the limit teeth 18 are controlled to be engaged with the fixed teeth 13 again, so as to automatically lock the elastic bracket 2, achieving the effects of simple and convenient operation and being able to automatically provide a locking force for the elastic bracket 2.
