Description

Technical Field

[0001] This application belongs to the technical field of sound recording devices, and particularly relates to a bracket and a sound recording device. Background Art

[0002] A sound recording device is a tool for capturing and recording sounds. For example, a microphone is an electro-acoustic device and a transducer for converting sound into electricity. When sound waves act on the electro-acoustic element, a voltage is generated and then converted into electrical energy, thereby realizing the conversion of sound into electricity. Currently, a microphone includes a microphone body and a support for supporting the microphone body. The microphone body is rotatably arranged on the support, and the sound collection direction can be adjusted by rotating the microphone body.

[0003] However, the rotation range of the existing microphone body is limited by a stop block provided on the microphone body. When the microphone body rotates to the maximum angle, the stop block abuts against the support to prevent the microphone body from continuing to rotate. With this arrangement, if the user applies a large force or after long-term use, the support is liable to be deformed or even damaged under stress, and thus can no longer support the microphone body.

[0004] Therefore, the existing sound recording device has the defect that the support is liable to be deformed or even damaged under stress. Summary of the Utility Model

[0005] The purpose of the embodiments of this application is to provide a bracket and a sound recording device, which can solve the problem that the support in the related art is liable to be deformed or even damaged under stress.

[0006] In a first aspect, the embodiments of this application provide a bracket, which includes a rotating shaft assembly and a support. The rotating shaft assembly includes:

[0007] A rotating arm for connecting with the sound collection body of the sound recording device;

[0008] A rotating shaft rotatably connected to the rotating arm. The support is connected to the rotating shaft, and a damping component is provided on one of the rotating shaft and the rotating arm;

[0009] Wherein, a limiting part is provided on one of the rotating arm and the rotating shaft, and the limiting part is used to limit the rotation angle of the rotating shaft relative to the rotating arm in the circumferential direction of the rotating shaft.

[0010] In a second aspect, the embodiments of this application further provide a sound recording device, which includes a sound collection body and the above-mentioned bracket, and the rotating arm of the bracket is connected to the sound collection body.

[0011] In the embodiment of the present application, the damping component can provide a damping force between the rotating shaft and the rotating arm, enabling the sound collection main body of the sound collection device to be positioned arbitrarily within a preset angle to maintain the required angle. At the same time, the damping component can also prevent the components from colliding and being damaged due to excessive force when the user rotates the sound collection main body. Moreover, the limiting portion on one of the rotating arm and the rotating shaft can limit the rotating shaft in the circumferential direction of the rotating shaft, thereby restricting the rotation angle of the rotating shaft relative to the rotating arm, that is, enabling the sound collection main body to rotate within a preset angle, and thus avoiding damage to the sound collection main body due to excessive rotation angle. At the same time, since the limiting portion is provided on one of the rotating arm and the rotating shaft and limits the rotating shaft, it does not contact the support during use, and the support is not easily affected by the force of the limiting portion. Therefore, the support is not easily deformed by force, and thus the service life of the support can be extended. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, rather than all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0037] The terms "first", "second", "third", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", "third", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally indicates an "or" relationship between the associated objects before and after.

[0038] The following will combine the drawings to describe in detail the bracket and the sound collection device provided by the embodiments of this application through specific embodiments and their application scenarios.

[0039] Refer to Figures 1-11 , a bracket provided by an embodiment of this application may include a rotating shaft assembly 200 and a support 300. The rotating shaft assembly 200 may include a rotating arm 210 and a rotating shaft 220. The rotating arm 210 may be used to connect to the sound collection main body 100 of the sound collection device. The rotating shaft 220 may be rotatably connected to the rotating arm 210. The support 300 may be connected to the rotating shaft 220, and a damping assembly 230 may be provided on one of the rotating shaft 220 and the rotating arm 210. The damping assembly 230 may enable a damping force between the rotating shaft 220 and the rotating arm 210, so that the sound collection main body 100 of the sound collection device can be arbitrarily positioned within a preset angle to maintain the required angle. At the same time, the damping assembly 230 can prevent the components from colliding and being damaged due to excessive force when the user rotates the sound collection main body 100.

[0040] A limiting portion 240 may be provided on one of the rotating arm 210 and the rotating shaft 220. The limiting portion 240 may be used to limit the rotation angle of the rotating shaft 220 relative to the rotating arm 210 in the circumferential direction of the rotating shaft 220, so that the sound collection main body 100 can rotate within a preset angle, thereby avoiding damage to the sound collection main body 100 due to excessive rotation angle. At the same time, since the limiting portion 240 is provided on one of the rotating arm 210 and the rotating shaft 220, and the limiting portion 240 limits the rotating shaft 220 and does not contact the support 300 during use, the support 300 is not easily affected by the acting force of the limiting portion 240. Therefore, the support 300 is not easily deformed by force, and thus the service life of the support 300 can be extended.

[0041] In an alternative embodiment of the present application, the limiting portion 240 may be provided on the rotating shaft 220. A through hole 213 and a limiting hole 214 may be provided on the rotating arm 210. The limiting hole 214 may communicate with the through hole 213. Moreover, the rotating shaft 220 may pass through the through hole 213 and be rotatable within the through hole 213. The limiting portion 240 may be located within the limiting hole 214 and be rotatable within the limiting hole 214. In this way, the rotational connection between the rotating arm 210 and the rotating shaft 220 can be achieved. Of course, the limiting portion 240 may also be provided on the rotating arm 210.

[0042] Here, the way of providing the limiting portion 240 on the rotating shaft 220 is more convenient for machining and helps to reduce the machining difficulty compared to the way of providing the limiting portion 240 on the rotating arm 210.

[0043] Among them, the hole wall of the limiting hole 214 may include a first limiting wall 2141 and a second limiting wall 2142, and the limiting portion 240 may be in limiting cooperation with the first limiting wall 2141 and the second limiting wall 2142 respectively. In this way, the structure of the rotating shaft assembly 200 can be simplified and it is convenient for machining and manufacturing.

[0044] Optionally, the first limiting wall 2141 and the second limiting wall 2142 may be of a planar structure, and the included angle α between the plane where the first limiting wall 2141 is located and the plane where the second limiting wall 2142 is located may be 50°, so that the rotating shaft 220 can rotate relative to the rotating arm 210 within a range of 0 to 50°. Of course, the included angle α between the plane where the first limiting wall 2141 is located and the plane where the second limiting wall 2142 is located may also be other values, and the embodiments of the present application do not limit this.

[0045] In other embodiments, the limiting hole 214 may not be provided on the rotating arm 210, that is, only the through hole 213 is provided on the rotating arm 210. Moreover, the limiting portion 240 may be provided on the rotating shaft 220 and be located on one side of the through hole 213. A limiting stop block may also be provided on the rotating arm 210. The limiting stop block and the limiting portion 240 are on the same side of the rotating shaft 220, and the limiting portion 240 may be in limiting cooperation with the limiting stop block in the circumferential direction of the rotating shaft 220 to limit the rotation angle of the rotating shaft 220 relative to the rotating arm 210.

[0046] In an alternative embodiment, the damping assembly 230 may include a spring piece 231 and a locking member 232. Both the spring piece 231 and the locking member 232 may be sleeved outside the rotating shaft 220. Moreover, the spring piece 231 may be located between the rotating arm 210 and the locking member 232, and the spring piece 231 may abut against the rotating arm 210 to be able to apply a damping force to the rotating arm 210. Here, the way of using the spring piece 231 to achieve the damping effect occupies less space compared to the way of using a spring to achieve the damping effect, and can bear a larger load within a limited space, as well as having a low maintenance cost.

[0047] Of course, in other embodiments, a spring may also be used to replace the elastic sheet 231.

[0048] Optionally, the damping assembly 230 may include at least two elastic sheets 231. Each elastic sheet 231 may be sleeved outside the rotating shaft 220 and connected in sequence along the axial direction of the rotating shaft 220. In this way, the damping effect can be improved. Here, the elastic sheets 231 may be arranged in an overlapping manner or side by side.

[0049] It should be noted that in this embodiment, the number and specifications of the elastic sheets 231 are not limited. Specifically, the number and specifications of the elastic sheets 231 may be set according to the required damping force to achieve different rotation feels.

[0050] Optionally, the locking member 232 may move along the rotating shaft 220 to adjust the elastic force of the elastic sheet 231, and further adjust the damping force between the rotating shaft 220 and the rotating arm 210.

[0051] Here, the locking member 232 may be a locking nut. External threads may be provided on the rotating shaft 220, and the locking nut may be threadedly connected to the rotating shaft 220. Tightening the locking member 232 can increase the elastic force of the elastic sheet 231, and loosening the locking member 232 can decrease the elastic force of the elastic sheet 231.

[0052] In addition, the damping assembly 230 may further include an anti-rotation gasket 233. The anti-rotation gasket 233 may be sleeved outside the rotating shaft 220. The anti-rotation gasket 233 may be located between the locking member 232 and the elastic sheet 231, and the anti-rotation gasket 233 and the rotating shaft 220 may be in circumferential limit fit. In this way, during the relative rotation of the rotating shaft 220 and the rotating arm 210, when the elastic sheet 231 rotates relative to the rotating shaft 220 under the action of the rotating arm 210, the anti-rotation gasket 233 can prevent the locking member 232 from rotating relative to the rotating shaft 220, so that the locking member 232 can still lock the elastic sheet 231, and further ensure that the damping force between the rotating shaft 220 and the rotating arm 210 does not change.

[0053] Here, a first plane 2221 may be provided on the rotating shaft 220, and a second plane 2331 may be provided on the inner wall of the anti-rotation gasket 233. The first plane 2221 and the second plane 2331 may be in contact with each other to enable the anti-rotation gasket 233 and the rotating shaft 220 to be in circumferential limit fit.

[0054] In other embodiments, the damping assembly 230 may not include the anti-rotation gasket 233. Specifically, the locking member 232 may be in direct contact with the elastic sheet 231.

[0055] In an alternative embodiment, such as Figure 2As shown, the rotating shaft assembly 200 may include two rotating arms 210. The rotating arm 210 includes a connecting plate 212, and the connecting plate 212 can be used for fitting connection with the sound receiving main body 100.

[0056] Wherein, one of the two rotating arms 210 can rotate 180° around a preset axis and coincide with the other. It should be noted that the preset axis coincides with the axis of the rotating shaft 220 and is perpendicular to the connecting plate 212. In this way, the two rotating arms 210 can be parts with the same structure, which not only improves the reuse rate, reduces the production cost, but also simplifies the manufacturing and assembly processes. And since only one set of molds and processing equipment is needed, production management can become more efficient.

[0057] Optionally, the rotating arm 210 may further include a rotating plate 211 connected to the connecting plate 212. The through hole 213 and the limiting hole 214 may be located on the rotating plate 211. Specifically, the rotating plate 211 can be perpendicularly connected to the connecting plate 212.

[0058] Here, two limiting portions 240 may be provided on the rotating shaft 220, and the two limiting portions 240 may be respectively located in the two limiting holes 214 on the two rotating arms 210.

[0059] In one way, the two limiting portions 240 may be respectively located on opposite sides of the rotating shaft 220 for circumferential limiting cooperation with the two rotating arms 210 respectively.

[0060] In another way, the two limiting portions 240 may not be respectively located on opposite sides of the rotating shaft 220. Specifically, the positional relationship of the two limiting portions 240 only needs to meet the following requirements:

[0061] Here, the limiting holes 214 on the two rotating arms 210 are respectively referred to as the first limiting hole 2143 and the second limiting hole 2144, and the two limiting portions 240 are respectively referred to as the first limiting portion 2401 and the second limiting portion 2402. When the first limiting portion 2401 abuts against the first limiting wall 2141 of the first limiting hole 2143, the second limiting portion 2402 abuts against the second limiting wall 2142 of the second limiting hole 2144; when the first limiting portion 2401 abuts against the second limiting wall 2142 of the first limiting hole 2143, the second limiting portion 2402 abuts against the first limiting wall 2141 of the second limiting hole 2144.

[0062] In other embodiments, one of the two rotating arms 210 cannot coincide with the other after rotating 180° around a preset axis, so that the two rotating arms 210 are parts with different structures.

[0063] Optionally, the rotating shaft 220 may include a support connection part 221 and two rotating parts 222. The support connection part 221 may be connected to the support 300. The two rotating parts 222 may be respectively connected to both ends of the support connection part 221. The rotating shaft assembly 200 may include two rotating arms 210. The two rotating parts 222 may be respectively rotatably connected to the two rotating arms 210, and damping assemblies 230 may be provided on both of the two rotating parts 222. The elastic pieces 231 of the two damping assemblies 230 may respectively abut against the two rotating arms 210, and limiting parts 240 may also be provided on both of the two rotating parts 222. In this way, the balance of the sound collecting body 100 can be improved. Of course, the rotating shaft 220 may also only include one rotating part 222, and the rotating shaft assembly 200 may also only include one rotating arm 210.

[0064] Here, convex parts 2212 may be provided at both ends of the support connection part 221. The convex parts 2212 and the rotating arm 210 may be in axial limiting cooperation on the rotating shaft 220 to prevent relative movement between the rotating arm 210 and the rotating shaft 220 in the axial direction.

[0065] In an alternative embodiment of the present application, the support 300 may include a base 310 and a connector 320. A first connecting piece 311 may be provided on the base 310. The first connecting piece 311 may be used for electrically connecting with a power supply component. One end of the connector 320 may be provided with a second connecting piece 323. The second connecting piece 323 may be used for electrically connecting with the sound collecting body 100, and the first connecting piece 311 and the second connecting piece 323 may be inserted and electrically connected. In this way, it is convenient to disassemble and assemble the base 310 and the connector 320 to facilitate the repair or replacement of the base 310 or the connector 320. Of course, the first connecting piece 311 and the second connecting piece 323 may also be fixedly connected in a non-detachable manner, or the first connecting piece 311 and the second connecting piece 323 may also be fixedly connected by fixing screws.

[0066] Here, the other end of the connector 320 may be connected to the rotating shaft 220 to realize the connection between the support 300 and the sound collecting body 100.

[0067] In an alternative embodiment, the bracket may further include a wire 330. The first end of the wire 330 may be electrically connected to the second connecting piece 323. The connector 320 may be provided with a wire passing hole 321. The other end of the wire 330 may be used to pass through the wire passing hole 321 and connect to the sound collecting body 100 so that the first connecting piece 311 is electrically connected to the sound collecting body 100, and further the power supply component can supply power to the sound collecting body 100 through the wire 330.

[0068] The bracket may further include an adapter 340. The connector 320 may be connected to the rotating shaft 220 through the adapter 340. In this way, it is convenient to connect the rotating shaft 220 and the connector 320.

[0069] Of course, the bracket may not include the adapter 340. The connector 320 can be directly connected to the rotating shaft 220. Specifically, the connector 320 can be provided with a connection hole, and the rotating shaft 220 can pass through the connection hole and be circumferentially limited and matched with the hole wall of the connection hole to realize the connection between the rotating shaft 220 and the connector 320. Alternatively, the connector 320 can be adhesively bonded to the rotating shaft 220.

[0070] Furthermore, the adapter 340 can be embedded in the wire passing hole 321. In this way, the contact area between the connector 320 and the adapter 340 can be increased, which is beneficial to improving the connection strength between the connector 320 and the adapter 340. And it can avoid the exposure of the adapter 340, which is beneficial to improving the aesthetics of the sound receiving device. Of course, the adapter 340 may not be embedded in the wire passing hole 321, and one end of the adapter 340 facing away from the rotating shaft 220 can be directly connected to one end of the connector 320 facing away from the base 310.

[0071] Optionally, the adapter 340 can be connected to the rotating shaft 220 through a first screw, and the adapter 340 can be connected to the connector 320 through a second screw. In this way, the connection stability between the connector 320 and the rotating shaft 220 can be improved. Here, the rotating shaft 220 can be provided with a first connection hole 2211, and the first screw can pass through the first connection hole 2211 and be threadedly connected to the adapter 340 to realize the connection between the rotating shaft 220 and the adapter 340. The connector 320 can be provided with a second connection hole 322, and the second screw can pass through the second connection hole 322 and be connected to the adapter 340 to realize the connection between the connector 320 and the adapter 340.

[0072] In an alternative embodiment, the adapter 340 can be provided with a wire groove 341 for the wire 330 to pass through. In this way, the adapter 340 will not interfere with the wire 330, and thus will not affect the layout of the wire 330, and there is no need to additionally provide a perforation for the wire 330 to pass through on the connector 320.

[0073] Of course, the wire groove 341 may not be provided on the adapter 340. Specifically, the connector 320 can be provided with a perforation for the wire 330 to pass through. The perforation can communicate with the wire passing hole 321, and the axis of the perforation can intersect with the axis of the wire passing hole 321.

[0074] Based on the bracket provided by the embodiments of the present application, the embodiments of the present application further provide a sound receiving device, which can include a sound receiving main body 100 and the bracket described in any of the above embodiments. The swing arm 210 of the bracket can be connected to the sound receiving main body 100.

[0075] In an alternative embodiment of the present application, the sound receiving main body 100 can be a square tube microphone, that is, the shape of the sound receiving main body 100 is a cuboid.

[0076] The beneficial effects achieved by the radio device provided in the embodiment of the present application are consistent with the beneficial effects achieved by the bracket provided in the embodiment of the present application, and will not be repeated here.

[0077] In an optional embodiment of the present application, the sound receiving body 100 may be provided with a cavity 110, an inlet and outlet 130 and a mounting hole 120, and the sound receiving device may further include a slider 400, which may be used to enter the cavity 110 through the inlet and outlet 130 and connect with the sound receiving body 100, and the slider 400 may be provided with a receiving groove 410. When the slider 400 is located in the cavity 110, the notch of the receiving groove 410 may be opposite to the mounting hole 120, so that the connector 320 described below can extend from the receiving groove 410.

[0078] The support 300 of the bracket may include a connector 320. When the slider 400 enters and exits the inlet and outlet 130, the connector 320 may be located in the receiving groove 410. This facilitates the assembly of the wire 330 to reduce the difficulty of connecting the wire 330 to the electroacoustic element of the sound receiving body 100.

[0079] Furthermore, when the slider 400 is located in the cavity 110, the rotating arm 210 can be connected to the slider 400, and the connector 320 can extend out of the receiving groove 410 through the notch of the receiving groove 410 and the mounting hole 120. In this way, it is convenient for the connector 320 to be connected to the base 310, so that the connector 320 can play the role of supporting the sound receiving body 100.

[0080] In other embodiments, the sound receiver body 100 may not be provided with the cavity 110 , the inlet and outlet 130 and the mounting hole 120 , and the sound receiver device may not include the slider 400 , and the rotating arm 210 of the rotating shaft assembly 200 may be directly connected to the sound receiver body 100 .

[0081] In this embodiment, a sound receiving hole may be provided at one end of the sound receiving body 100 , and the inlet and outlet 130 may be provided at the end of the sound receiving body 100 away from the sound receiving hole.

[0082] Optionally, in order to facilitate the sliding of the slider 400, a slide groove 430 can be provided on the slider 400, and a slide rail 150 can be provided in the cavity 110. The slide rail 150 can be slidably connected to the slide groove 430. Here, the slide rail 150 can be set along the length direction of the sound receiving body 100.

[0083] Among them, two sliding grooves 430 can be provided on the slider 400, and two sliding rails 150 can be provided in the cavity 110. The two sliding grooves 430 can be respectively slidably connected to the two sliding rails 150, so that the connection strength between the slider 400 and the sound receiving main body 100 can be improved. Of course, only one sliding groove 430 can also be provided on the slider 400, and only one sliding rail 150 can also be provided in the cavity 110.

[0084] Moreover, after the slider 400 enters the cavity 110, the slider 400 can be connected to the sound receiving main body 100 through a fixing nail.
