Description

Technical Field

[0001] The invention relates to the technical field of near-ear sound, in particular to a highly adaptable near-ear sound and a highly sensitive audio broadcasting device. Background Art

[0002] Near-ear speakers are different from in-ear speakers. They do not need to be inserted deep into the ear canal when used. The sound unit covers the auricle. Compared with in-ear speakers, near-ear speakers can avoid scratching the ear canal, have better comfort, and can be worn for a relatively longer time.

[0003] Close-to-ear speakers usually consist of earmuffs, a headband, and a telescopic rod. The telescopic rod is used to adjust the length of the headband, thereby changing the tightness of the earphones. Gradually adjust the length of the telescopic rod according to the size of your head. If your head is large, you can stretch the telescopic rod outward; if your head is small, you can retract the telescopic rod inward. Be careful to keep the length of the telescopic rods on both sides the same to ensure balance when wearing.

[0004] After the size adjustment of existing near-ear speakers is completed, they are usually simply locked by damping. With long-term use, the damping may fail. In addition, during the adjustment process, the extension and retraction of the telescopic rods on both sides cannot be synchronously controlled to remain consistent. This will cause the two earmuffs to be in an asymmetric position, resulting in problems such as subsequent wearing deviation and looseness. Summary of the invention

[0005] The object of the present invention is to provide a highly adaptable near-ear sound system and a highly sensitive audio broadcasting device to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a highly adaptable near-ear speaker, comprising: a sleeve plate, and an elastic bracket slidably installed in the sleeve plate and symmetrically arranged, the end of the elastic bracket is hinged with a connecting rod, and a loudspeaker is fixed on the connecting rod; it also includes: a spacing adjustment mechanism, which is arranged in the sleeve plate and connected to the elastic bracket, and the spacing adjustment mechanism can adjust the spacing between the two loudspeakers through the elastic bracket and the connecting rod; a follow-up bending component, which is arranged on the sleeve plate and connected to the elastic bracket, and the follow-up bending component can be actuated when the spacing adjustment mechanism moves to adjust the bending angle of the elastic bracket; a locking mechanism, which is arranged in the sleeve plate and connected to the spacing adjustment mechanism, and an unlocking mechanism connected to the locking mechanism is also arranged in the sleeve plate, and the unlocking mechanism can lock or unlock the spacing adjustment 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 effect of the present invention is that the present application can adjust the distance between the two players through the cooperation of the locking mechanism and the unlocking mechanism, and automatically lock the position of the speaker after the adjustment is completed. Specifically, in the initial state, under the action of the locking mechanism, the elastic bracket is controlled to be in a locked state through the distance adjustment mechanism. If the user's head circumference does not match the size of the speaker, the distance between the two speakers needs to be adjusted. At this time, the unlocking mechanism can be manually controlled to move, and the locking mechanism can be driven to move, so that the locking mechanism no longer locks the distance adjustment mechanism. At this time, the size of the elastic bracket and the sleeve plate can be freely adjusted, and under the action of the distance adjustment mechanism, the movement stroke of the two elastic brackets can be ensured to be consistent at all times, thereby ensuring that the two speakers are kept consistent with the distance between the sleeve plate when adjusted. When the adjustment is completed, the force applied to the unlocking mechanism is removed, and the locking mechanism is automatically reset. Under the action of the locking mechanism, the elastic bracket is locked again by the distance adjustment mechanism.

[0016] When the elastic bracket moves, it can also drive the follow-up bending component to move. Under the action of the follow-up bending component, the bending angle of the end of the elastic bracket can be automatically adjusted according to the extension amount of the elastic bracket to ensure that the speaker can always fit the user's ear, so that the speaker will not loosen and fall off the user's head.

[0017] By controlling the matching state of the limit latch and the fixed latch, the elastic bracket can be adjusted and locked, so that the speaker has the advantages of simple use and convenient operation. If a large force is suddenly applied to the speaker or the elastic bracket due to misoperation or other factors during use, the follower plate is subjected to the thrust provided by the spring. Therefore, when the force applied to the sliding block is greater than the locking force provided by the limit latch and the fixed latch, the follower plate will give way under the action of the spring to prevent the locking force provided to the elastic bracket from conflicting with the excessive external force, resulting in damage to the elastic bracket.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0022] See also Figure 1 to Figure 11In an embodiment of the present invention, a highly adaptable near-ear speaker comprises: a sleeve plate 1, and an elastic bracket 2 slidably mounted in the sleeve plate 1 and symmetrically arranged, a connecting rod 3 is hinged at the end of the elastic bracket 2, and a loudspeaker 4 is fixed on the connecting rod 3; it also comprises: a spacing adjustment mechanism, which is arranged in the sleeve plate 1 and connected to the elastic bracket 2, and the spacing adjustment mechanism can adjust the spacing between the two loudspeakers 4 through the elastic bracket 2 and the connecting rod 3; a follower bending component, which is arranged on the sleeve plate 1 and connected to the elastic bracket 2, and the follower bending component can be actuated when the spacing adjustment mechanism moves to adjust the bending angle of the elastic bracket 2; a locking mechanism, which is arranged in the sleeve plate 1 and connected to the spacing adjustment mechanism, and an unlocking mechanism connected to the locking mechanism is also arranged in the sleeve plate 1, and the unlocking mechanism can lock or unlock the spacing adjustment mechanism through the locking mechanism.

[0023] Specifically, when using the present speaker, the fitting size of the two elastic brackets 2 and the sleeve plate 1 can be adjusted according to the user's head circumference, thereby adjusting the distance 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 by the locking mechanism, so that the two elastic brackets 2 can slide freely in the sleeve plate 1. At this time, the two elastic brackets 2 can be controlled to move in the direction of approaching or moving away from each other, and under the action of the spacing adjustment mechanism, the two elastic brackets 2 move in the sleeve plate 1 The size is the same, thereby ensuring that the distance between the two speakers 4 and the sleeve plate 1 is the same. When the elastic bracket 2 moves, it will also drive the follow-up bending component to move. Under the action of the follow-up bending component, when the distance between the two speakers 4 increases, the bending angle of the elastic bracket 2 is controlled to increase, or when the distance between the two speakers 4 decreases, The bending angle of the elastic bracket 2 is controlled to decrease, so as to ensure that the two speakers 4 are more closely fitted to the user's ears, thereby ensuring that the present speaker can be adapted to the use of different users.

[0024] See also Figure 3-Figure 5 , Figure 7 , Fig.11 The spacing adjustment mechanism includes a slide groove 9 provided on the side wall of the sleeve plate 1, a sliding block 12 that can slide up and down is slidably installed in the slide groove 9, an arc-shaped limit plate 11 placed in the sleeve plate 1 is fixed to the side wall of the sliding block 12, and a guide component connected to the elastic bracket 2 is provided on the arc-shaped limit plate 11, wherein the guide component includes a corrugated groove 1101 provided on the side of the arc-shaped limit plate 11 and symmetrically arranged, a limit block 8 is fixed on the side of the elastic bracket 2, and the limit block 8 is slidably engaged with the corrugated groove 1101.

[0025] In detail, the corrugated groove 1101 is composed of two symmetrically arranged inclined grooves repeatedly combined, and the inclined grooves are arranged in multiple groups along the arc trajectory of the arc-shaped limit plate 11. In the initial state, the two limit blocks 8 are respectively located at the end of the stroke of the two corrugated grooves 1101 close to each other, so that the size of the two elastic brackets 2 inserted into the sleeve plate 1 is the largest, so that the distance between the two speakers 4 is controlled to be the smallest 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 sliding block 12 is released through the locking mechanism, so that the sliding block 12 can slide freely along the slide groove 9. At this time, any one or both elastic brackets can be driven manually. The elastic bracket 2 moves in the direction away from each other, thereby driving the limit 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 limit plate 11 to move up and down while moving away from each other, thereby driving the sliding block 12 to move along the length direction of the slide groove 9. Since the corrugated groove 1101 is symmetrically arranged, the positions of the two limit blocks 8 in the two corrugated grooves 1101 are consistent, ensuring that the dimensions of the two elastic brackets 2 and the sleeve plate 1 that fit each other always remain the same, so as to ensure that the distance between the speaker 4 and the center position of the sleeve plate 1 is the same, so that the speaker 4 can fit the user's ear when worn.

[0026] Preferably, after the elastic bracket 2 is adjusted to the desired position, the locking mechanism prevents the position of the sliding block 12 in the slide groove 9 from changing, and the position of the elastic bracket 2 is locked under the action of the corrugated groove 1101 and the limit block 8, to ensure that the speaker will not become loose when in use. The sleeve plate 1 is made of a hard material, and its outer surface is wrapped with a protective cover made of a soft material, which can increase the comfort of the user, thereby preventing discomfort to the head caused by the fit of the sleeve plate 1 against the user's head.

[0027] See also Figure 1-Figure 3 , Figure 5 , Fig.10 The follower bending assembly includes an arc-shaped support sleeve 5 fixedly mounted on the outside of the sleeve plate 1 and symmetrically arranged, an arc-shaped support plate 6 is slidably mounted 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.

[0028] 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 sleeve plate 1 is also arranged in an arc shape. Taking the center of the sleeve plate 1 as the center point, the center of the arc-shaped support sleeve 5 is located at a position where the center point is biased from the sleeve 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, taking the central axis of the sleeve plate 1 as a reference, the angle between the arc-shaped support sleeve 5 and the central axis of the sleeve plate 1 with the same arc length is smaller than the angle between the sleeve plate 1 with the same arc length and the central axis. In the initial state, the size of the elastic bracket 2 and the sleeve plate 1 fitting each other is the largest, and at the hinge rod 7 Under the action of , the size of the mutual fit of the arc support plate 6 and the arc support sleeve 5 is maximized. When the distance between the speakers 4 needs to be increased, the two elastic brackets 2 are controlled to move in the direction away from each other, and the hinge rod 7 is driven to move, so that the arc support plate 6 moves in the direction away from the arc support sleeve 5. As the arc support plate 6 moves, it will continue to move toward the direction of the elastic bracket 2. Under the action of the hinge rod 7, the ends of the two elastic brackets 2 close to the speakers 4 continue to swing toward the direction of approaching each other. When the adjustment is completed, under the action of the locking mechanism, the position of the elastic bracket 2 no longer changes.

[0029] Preferably, when it is necessary to increase the distance between the two speakers 4, the elastic bracket 2 can be controlled to gradually swing toward the central axis direction of the sleeve plate 1 through the cooperation of the arc support plate 6 and the hinge rod 7, thereby ensuring that the speaker 4 can always fit the user's ear, wherein the arc support sleeve 5 is fixed in a manner of being sleeved on a rotating shaft, and the rotating shaft is fixed to the sleeve plate 1 by bolts. During normal use, the rotating shaft can be fixed by bolts so that the angle of the arc support sleeve 5 does not change, and the initial angle of the arc support sleeve 5 can be adjusted by loosening the bolts, thereby adjusting the angle between the arc support sleeve 5 and the initial state of the sleeve plate 1, so as to change the deformation amount of the end of the elastic bracket 2 when the size of the elastic bracket 2 is adjusted according to actual needs, thereby further increasing the application range of the present speaker.

[0030] See also Figure 2 , Figure 5-Figure 9 , Fig.11 The locking mechanism includes a fixed sleeve 14 fixedly installed in the sleeve plate 1 and symmetrically arranged, a movable rod 15 is slidably installed in the fixed sleeve 14, a spring 16 is sleeved on the fixed sleeve 14 and the movable rod 15, and a limiting assembly connected to the sliding block 12 is provided on the movable rod 15, wherein the limiting assembly 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 movable rod 15, the follower plate 17 is in contact with the spring 16, and a limiting tooth 18 engaged with the fixed tooth 13 is fixed on the follower plate 17.

[0031] Furthermore, the side of the follower plate 17 away from the arc-shaped limit plate 11 is set in a right-angled trapezoidal shape, and the inclined surface of the right-angled trapezoidal part cooperates with the unlocking mechanism. In the initial state, the unlocking mechanism is not subjected to 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 away from the fixed sleeve 14. Under the action of the follower plate 17, the limit latch 18 and the fixed latch 13 are controlled to be in a locked state, so that the position of the sliding block 12 is locked by the limit latch 18 and the fixed latch 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, thereby driving the movable rod 15 to move toward the fixed sleeve 14. The spring 16 is elastically released and drives the following plate 17 to move toward the sliding block 12 to drive the movable rod 15 to move in the direction away from the fixed sleeve 14. At the same time, the following plate 17 also drives the limiting tooth 18 to move. When the limiting tooth 18 is engaged with the fixed tooth 13 again, the position of the sliding block 12 is locked again.

[0032] Preferably, by controlling the matching state of the limit latch 18 and the fixed latch 13, the elastic bracket 2 can be adjusted and locked, so that the present speaker has the advantages of simple use and convenient operation. If the present speaker is in use, due to misoperation or other factors, a large force is suddenly applied to the speaker 4 or the elastic bracket 2, because the follower plate 17 is subjected to the thrust provided by the spring 16, therefore, when the force applied to the sliding block 12 is greater than the locking force provided by the limit latch 18 and the fixed latch 13, under the action of the spring 16, the follower plate 17 will give way to prevent the locking force provided to the elastic bracket 2 from conflicting with the excessive external force, resulting in damage to the elastic bracket 2.

[0033] See also Figure 2 , Figure 5-Figure 9 , Fig.11The unlocking mechanism includes a through slot 10 provided on the sleeve plate 1, a limiting sleeve 19 is fixed on the sliding block 12, a push rod 21 slidably connected to the through slot 10 is slidably installed in the limiting sleeve 19, a pushing ring 22 is fixed to the end of the push rod 21 away from the limiting sleeve 19, a pushing assembly connected to the push rod 21 is provided on the limiting sleeve 19, wherein the pushing assembly includes a slot 20 provided on the circumferential outer wall of the limiting sleeve 19, a movable plate 23 slidably connected to the slot 20 is fixed on the push rod 21, and a symmetrically arranged tilting block 24 is fixed on the movable plate 23, and the tilting block 24 is in contact with the follower plate 17.

[0034] Furthermore, the tilting block 24 is arranged in an inclined shape, and the inclined surface is in conflict with the inclined surface 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 latch 18 is in a locked state with the fixed latch 13. Under the action of the inclined surface of the follower plate 17, the tilting block 24 is located at the end of the stroke away from the sliding block 12, so that the movable plate 23 is located at the end of the stroke of the slot 20 away from the sliding block 12. When the distance between the speakers 4 needs to be adjusted, at this time, the push ring 22 can be manually controlled to move toward the direction of the sleeve plate 1, and the push rod 21 can be driven to move toward the limit sleeve 19, thereby driving the movable plate 23 to move along the length direction of the slot 20. The plate 23 will also drive the tilting block 24 to move. When the inclined surface of the tilting 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 tooth 18 is separated from the fixed tooth 13 to ensure 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 elastic bracket 2 is adjusted, the distance between the two speakers 4 is adapted to the user's head circumference. At this time, the spring 16 is elastically released and drives the follower plate 17 to move toward the sliding block 12, so as to drive the limit tooth 18 to move again to the engaging position with the fixed tooth 13. Under the action of the inclined surface of the follower plate 17 and the tilting block 24, the movable plate 23 and the push rod 21 are reset.

[0035] Preferably, the elastic bracket 2 can be unlocked by pressing the push ring 22. At the same time, after the adjustment is completed, it is only necessary to remove the force applied to the push ring 22. Under the action of the spring 16, the push ring 22 can be automatically reset, and the limit tooth 18 can be controlled to engage with the fixed tooth 13 again, thereby automatically locking the elastic bracket 2, so as to achieve simple and convenient operation, and can automatically provide a locking force for the elastic bracket 2.
