Description

Technical Field

[0001] This application relates to the field of acoustic equipment testing technology, and in particular to a sound leakage detection device. Background Technology

[0002] Acoustic devices refer to various devices that can generate, process, transmit, or receive sound signals, such as headphones, VR headsets, and smart glasses. During use, acoustic devices may experience sound leakage, which means that sound is unexpectedly leaked from inside the acoustic device to the outside. Sound leakage detection devices can detect situations where sound is unexpectedly leaked to the outside when the acoustic device is playing sound.

[0003] In related technologies, a sound leakage detection device includes a base, a support platform, and a support column. The support platform and support column are installed on the base. A test dummy wearing acoustic equipment is placed on the support platform. A bracket is set on the support column, and multiple microphones are installed on the bracket. These microphones are distributed around the test dummy. When the acoustic equipment plays sound, these microphones simultaneously collect sound signals from the surrounding space. By analyzing information such as the sound pressure level, phase, and propagation characteristics of the sound signals received by the microphones at different locations, the intensity, direction, and source location of the sound leakage can be accurately determined.

[0004] However, when moving the sound leakage detection device, the base is used to move the support column, bracket and multiple microphones as a whole. The overall weight of the sound leakage detection device is relatively heavy, making it inconvenient to move the entire sound leakage detection device. Utility Model Content

[0005] This application provides a sound leakage detection device to solve the technical problem that related sound leakage detection devices require the support column, bracket and multiple microphones to be moved as a whole during transportation, which makes it inconvenient to transport the sound leakage detection device.

[0006] This application provides a sound leakage detection device, including:

[0007] Base;

[0008] A support column is mounted on the base.

[0009] A bracket, which is mounted on the support column;

[0010] A first mounting component is used to detachably connect the bracket and the support column;

[0011] Multiple microphones, all of which are mounted on the bracket;

[0012] Multiple second mounting components, each of the microphones being detachably connected to the bracket via a corresponding second mounting component.

[0013] In some embodiments, the first mounting assembly includes a first mounting plate, a second mounting plate, and at least two first mounting members. The first mounting plate is disposed on the support column, the second mounting plate is disposed on the bracket, and the first mounting members are used to simultaneously pass through or detach from the first mounting plate and the second mounting plate to fix or detach the first mounting plate and the second mounting plate.

[0014] In some embodiments, a clamping plate is further included, and an installation space is formed between the clamping plate and the first mounting plate. The installation space is used for the second mounting plate to be moved in or out. The first mounting member is used to be simultaneously or separately inserted with the clamping plate, the first mounting plate and the second mounting plate to detachably connect the second mounting plate to the first mounting plate.

[0015] In some embodiments, the first mounting plate is provided with a groove for accommodating the clamping plate, and the mounting space is formed between the opposing surfaces of the clamping plate and the groove.

[0016] In some embodiments, the first mounting member includes a first mounting bolt for passing through and threadedly connected to the clamp, the first mounting plate, and the second mounting plate.

[0017] In some embodiments, each of the second mounting components includes a mounting block and at least two second mounting members. The mounting block is disposed on the bracket and has mounting holes for the microphone to be moved into or out. The second mounting members are used to fix or detach the microphone from the mounting holes.

[0018] In some embodiments, the mounting block includes a first mounting portion and a second mounting portion. The first mounting portion is disposed on the bracket and has a first mounting groove. The second mounting portion has a second mounting groove. The first mounting groove and the second mounting groove surround each other to form the mounting hole. The second mounting member is used to simultaneously pass through or detach from the first mounting portion and the second mounting portion to fix or detach the first mounting portion and the second mounting portion.

[0019] In some embodiments, the second mounting member includes a second mounting bolt, which is used to pass through the second mounting portion and to be threadedly connected to the first mounting portion.

[0020] In some embodiments, a third mounting component is further included, with at least two third mounting components provided on each of the first mounting portions. The third mounting components are used to pass through or detach from the first mounting portion and the bracket to fix or detach the first mounting portion from the bracket.

[0021] In some embodiments, at least one cable management tray is further included, which is disposed on the support column. The cable management tray has a plurality of cable management holes arranged along its circumference, which are used for moving the corresponding microphone wires into or out.

[0022] This application provides a sound leakage detection device. A first mounting assembly detachably connects the bracket and support column. When the sound leakage detection device needs to be moved, the bracket is removed from the support column, allowing multiple microphones to be removed as well. This facilitates the individual movement of the base and bracket, preventing the overall weight of the sound leakage detection device from hindering movement and improving its ease of transport. A second mounting assembly detachably connects the multiple microphones to the bracket. When the bracket needs to be moved, the multiple microphones are removed from the bracket, facilitating the individual movement of the bracket and microphones. This prevents the weight of the bracket and microphones from hindering movement and also prevents the microphone wires from interfering with the movement of the bracket, further improving its ease of transport.

[0038] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0039] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0040] In related technologies, sound leakage detection devices include a base, a support platform, and a support column. The base serves as the foundational structure of the entire device, providing stable support. The support platform and support column are mounted on the base. The support platform holds a test dummy wearing the acoustic equipment to simulate real-world usage scenarios. The support column is equipped with a bracket, on which multiple microphones are mounted, surrounding the test dummy. When the acoustic equipment plays sound, these microphones simultaneously collect sound signals from the surrounding space. Through specialized analysis software and algorithms, detailed analysis is performed on the sound pressure level, phase, and propagation characteristics of the sound signals received by the microphones at different locations. This allows for the precise determination of the intensity, direction, and specific source of sound leakage. This detection method provides a scientific basis for the optimized design of acoustic equipment, ensuring that sound leakage does not occur during use.

[0041] However, in actual use, the sound leakage detection device is difficult to move. During the movement, the base is used to move the support column, bracket and multiple microphones as a whole. Due to the structural design of the support column, bracket and multiple microphones, the weight of the entire sound leakage detection device is significantly increased. This increased weight not only puts a great physical burden on the movers, but may also cause instability during the movement, increasing the risk of damage to the device.

[0042] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0043] Combination Figures 1 to 4 This application provides a sound leakage detection device, comprising:

[0044] The system comprises a base 100, a support column 200, a bracket 300, a first mounting component 400, multiple microphones 500, and multiple second mounting components 600. The support column 200 is mounted on the base 100, and the bracket 300 is mounted on the support column 200. The first mounting component 400 is used to detachably connect the bracket 300 and the support column 200. The multiple microphones 500 are all mounted on the bracket 300, and each microphone 500 is detachably connected to the bracket 300 through a corresponding second mounting component 600.

[0045] In this application, by using a first mounting component 400 to detachably connect the bracket 300 and the support column 200, when the sound leakage detection device needs to be moved, the bracket 300 can be removed from the support column 200, allowing the bracket 300 to pull off multiple microphones 500. This facilitates the separate movement of the base 100 and the bracket 300, preventing the heavy weight of the entire sound leakage detection device from making it inconvenient to move, and improving the ease of movement of the sound leakage detection device. By using a second mounting component 600 to detachably connect the multiple microphones 500 to the bracket 300, when the bracket 300 needs to be moved, the multiple microphones 500 can be removed from the bracket 300, facilitating the separate movement of the bracket 300 and the multiple microphones 500. This prevents the heavy weight of the bracket 300 and the multiple microphones 500 from making it inconvenient to move, and also prevents the wires of the multiple microphones 500 from affecting the movement of the bracket 300, thus improving the ease of movement of the bracket 300.

[0046] In this embodiment, when manual handling is used, the base 100 and the bracket 300 are handled separately, which can prevent the sound leakage detection device from being too heavy to be pushed and handled manually, thus saving some manpower. When handling equipment such as a handling vehicle is used, the base 100 and the bracket 300 are handled separately, eliminating the need for a large handling vehicle. A smaller handling vehicle can be used to facilitate handling.

[0047] In this embodiment, the pickup 500 is a microphone. When the acoustic device plays sound, these microphones will simultaneously collect the sound signals of the surrounding space. By analyzing the sound pressure level, phase and propagation characteristics of the sound signals received by the microphones at different locations, the intensity, direction and source location of the leaked sound can be accurately determined.

[0048] In this embodiment, the sound leakage detection device further includes a support platform 700, which is disposed on the base 100. A test dummy wearing acoustic equipment is placed on the support platform 700. The sound leakage detection device also includes an adjustment mechanism, which is disposed on the base 100 and connected to the bracket 300 and the support platform 700. The adjustment mechanism is used to adjust the relative position of the bracket 300 and the support platform 700, so that the bracket 300 can drive multiple microphones 500 to different positions around the test dummy to achieve sound leakage detection, thereby indirectly increasing the detection range of sound leakage detection and thus indirectly improving the detection accuracy.

[0049] The first mounting assembly 400 includes a first mounting plate 410, a second mounting plate 420, and at least two first mounting members 430. The first mounting plate 410 is disposed on the support column 200, and the second mounting plate 420 is disposed on the bracket 300. The first mounting members 430 are used to simultaneously pass through or detach from the first mounting plate 410 and the second mounting plate 420 to fix or detach the first mounting plate 410 and the second mounting plate 420.

[0050] In this embodiment, a rotating shaft 210 is rotatably connected to the support column 200. A fixing block 220 is detachably connected to one end of the rotating shaft 210. The fixing block 220 is sleeved on the rotating shaft 210, and a fixing bolt for insertion and threaded connection to the rotating shaft 210 is passed through the fixing block 220. The fixing block 220 is detachably connected to the rotating shaft 210 through the fixing bolt. A first mounting plate 410 is disposed on the fixing block 220 and is disposed on the support column 200 through the fixing block 220. The fixing block 220 and the first mounting plate 410 are integrally disposed.

[0051] In this embodiment, the bracket 300 is arc-shaped, the second mounting plate 420 is integrally formed with the bracket 300, and the second mounting plate 420 is located in the middle of the arc-shaped bracket 300. The first mounting plate 410 and the second mounting plate 420 are overlapped, and the first mounting plate 410 and the second mounting plate 420 have the same length.

[0052] In this embodiment, two first mounting members 430 are provided, and the two first mounting members 430 are respectively provided at both ends of the first mounting plate 410 and the second mounting plate 420 along the length direction; in other embodiments, the number of first mounting members 430 can be adjusted as needed, for example, four first mounting members 430 are provided, and the four first mounting members 430 are evenly distributed along the length direction of the first mounting plate 410 and the second mounting plate 420.

[0053] In this application, by using the first mounting plate 410 and the second mounting plate 420, it is possible to prevent the first mounting member 430 from being directly connected to the support column 200 and the bracket 300, which would cause damage to the structure of the support column 200 and the bracket 300, thus indirectly maintaining the strength of the support column 200 and the bracket 300. By using the method of simultaneously inserting the first mounting member 430, the first mounting plate 410, and the second mounting plate 420, the fixing between the first mounting plate 410 and the second mounting plate 420 is achieved. The fixing method is convenient and simple, improving the ease of assembly and disassembly of the bracket 300.

[0054] In other embodiments, the first mounting member 430 can be replaced by a snap fastener provided on the first mounting plate 410 and the second mounting plate 420. The first mounting plate 410 and the second mounting plate 420 can be disassembled and assembled by engaging or disengaging the snap fastener on the first mounting plate 410 with the snap fastener on the second mounting plate 420.

[0055] The sound leakage detection device also includes a clamping plate 800, and an installation space 810 is formed between the clamping plate 800 and the first mounting plate 410. The installation space 810 is used for the second mounting plate 420 to move in or out. The first mounting member 430 is used to be inserted or detached from the clamping plate 800, the first mounting plate 410 and the second mounting plate 420 at the same time, so as to detachably connect the second mounting plate 420 to the first mounting plate 410.

[0056] In this embodiment, the clamping plate 800 and the second mounting plate 420 have the same shape.

[0057] In this application, by adopting the clamping plate 800, the clamping plate 800 and the first mounting plate 410 can clamp the second mounting plate 420, thereby further improving the fixing strength of the second mounting plate 420, and thus indirectly improving the fixing strength of the bracket 300.

[0058] The first mounting plate 410 is provided with a groove 411 for accommodating the clamping plate 800, and the mounting space 810 is formed between the clamping plate 800 and the opposite surfaces of the groove 411.

[0059] In this embodiment, the first mounting plate 410 is L-shaped, allowing the clamping plate 800 to be easily moved into or out of the groove 411. In other embodiments, the first mounting plate 410 can be U-shaped, and the second mounting plate 420 can be moved into or out of the U-shaped groove 411 of the first mounting plate 410, which also enables the assembly and disassembly of the second mounting plate 420. Alternatively, the cross-section of the groove 411 can be dovetail-shaped, and the second mounting plate 420 can be fitted with the dovetail-shaped groove 411, which also enables the assembly and disassembly of the second mounting plate 420.

[0060] In this application, by adopting the setting of the groove 411, the groove 411 can accommodate the clamping plate 800 and the second mounting plate 420, thereby reducing the overall thickness of the clamping plate 800, the first mounting plate 410 and the second mounting plate 420, preventing the thicker clamping plate 800, the first mounting plate 410 and the second mounting plate 420 from occupying a large space. In addition, the groove 411 reduces the material used for the first mounting plate 410, thereby reducing the weight of the first mounting plate 410 and making it easier to handle the first mounting plate 410.

[0061] The first mounting component 430 includes a first mounting bolt, which is used to pass through and is threadedly connected to the clamping plate 800, the first mounting plate 410, and the second mounting plate 420.

[0062] In this application, the first mounting bolt can be a hexagonal bolt, a round head bolt, a countersunk head bolt, or a self-tapping bolt. Hexagonal bolts, due to their hexagonal head design, are easy to tighten and loosen with a wrench, providing stable fastening force. Round head bolts have a round head, making them more aesthetically pleasing. Countersunk head bolts have heads that can be completely recessed below the mounting surface, making the surface smoother. Self-tapping bolts have self-tapping threads, which can tap threads in softer materials without the need for pre-drilling, making installation convenient and quick. In addition, there are high-strength bolts, which have high material strength and can withstand greater tensile and shear forces, suitable for structural components requiring high-strength connections.

[0063] In other embodiments, the first mounting member 430 can also be replaced with a magnet. By providing magnets on both the first mounting plate 410 and the second mounting plate 420, the first mounting plate 410 and the second mounting plate 420 can be fixed together by magnetic attraction, thereby further facilitating the assembly and disassembly of the first mounting plate 410 and the second mounting plate 420.

[0064] Each second mounting assembly 600 includes a mounting block 610 and at least two second mounting members 620. The mounting block 610 is mounted on the bracket 300 and has mounting holes 611 for the microphone 500 to be moved into or out. The second mounting members 620 are used to fix or detach the microphone 500 from the mounting holes 611.

[0065] In this embodiment, the mounting block 610 is arranged along the length direction of the bracket 300, and the width of the mounting block 610 is smaller than the width of the bracket 300. There are two second mounting members 620, which are respectively arranged at both ends of the mounting block 610 along the length direction of the bracket 300. In other embodiments, the number of second mounting members 620 can be adjusted as needed. For example, four second mounting members 620 can be set and evenly distributed along the length direction of the mounting block 610.

[0066] In this embodiment, the microphone 500 has a circular cross-section, and the mounting hole 611 is configured to mate with the circular microphone 500. In other embodiments, when the shape of the microphone 500 changes, the mounting hole 611 can change accordingly. For example, when the cross-section of the microphone 500 is rectangular, the mounting hole 611 can be set to be rectangular to mate with the rectangular microphone 500.

[0067] In this application, by using a mounting block 610 and a mounting hole 611, and by passing the microphone 500 through the mounting hole 611, the mounting hole 611 can guide the microphone 500, preventing the microphone 500 from shifting away from the test dummy, thereby indirectly improving the testing accuracy of the microphone 500. By using a second mounting member 620, the second mounting member 620 can fix the microphone 500 in the mounting hole 611, thereby indirectly improving the fixing strength of the microphone 500 in the mounting hole 611.

[0068] The mounting block 610 includes a first mounting part 612 and a second mounting part 613. The first mounting part 612 is disposed on the bracket 300 and has a first mounting groove 614. The second mounting part 613 has a second mounting groove 615. The first mounting groove 614 and the second mounting groove 615 surround each other to form a mounting hole 611. The second mounting member 620 is used to pass through or detach from the first mounting part 612 and the second mounting part 613 simultaneously, so as to fix or detach the first mounting part 612 and the second mounting part 613.

[0069] In this embodiment, the first mounting portion 612 is T-shaped. The T-shaped first mounting portion 612 includes a first mounting segment 616 and a second mounting segment 617. The first mounting segment 616 is arranged along the length direction of the bracket 300, and the second mounting segment 617 is integrally arranged on the side of the first mounting segment 616 away from the bracket 300. The length of the second mounting segment 617 along the length direction of the bracket 300 is less than the length of the first mounting segment 616 along the length direction of the bracket 300. The second mounting segment 617 is located in the middle of the first mounting segment 616.

[0070] In this embodiment, the first mounting groove 614 is semi-circular and the second mounting groove 615 is semi-circular. When the first mounting groove 614 and the second mounting groove 615 are joined together, the first mounting groove 614 and the second mounting groove 615 can be joined together to form a circular mounting hole 611.

[0071] In this embodiment, two second mounting members 620 are respectively disposed at both ends of the second mounting section 617 along the length direction of the bracket 300.

[0072] In this application, by employing the first mounting part 612 and the second mounting part 613, misalignment of the microphone 500 with the mounting hole 611 is prevented, thereby facilitating the movement of the microphone 500 into or out of the mounting hole 611 and indirectly improving the ease of assembly and disassembly of the microphone 500. By using the first mounting member 430 to pass through the first mounting part 612 and the second mounting part 613, the first mounting part 612 and the second mounting part 613 are fixed. The fixing method is convenient and simple, further improving the ease of assembly and disassembly of the microphone 500. In addition, the first mounting member 430 can position the first mounting part 612 and the second mounting part 613, thereby preventing positional misalignment between the first mounting groove 614 and the second mounting groove 615.

[0073] The second mounting member 620 includes a second mounting bolt, which is used to pass through the second mounting part 613 and is used to thread a connection with the first mounting part 612.

[0074] In this application, the second mounting bolt can be a hexagonal bolt, a round head bolt, a countersunk head bolt, or a self-tapping bolt. Hexagonal bolts, due to their hexagonal head design, are easy to tighten and loosen with a wrench, providing stable fastening force. Round head bolts have a round head, making them more aesthetically pleasing. Countersunk head bolts have heads that can be completely recessed below the mounting surface, making the surface smoother. Self-tapping bolts have self-tapping threads, which can tap threads in softer materials without the need for pre-drilling, making installation convenient and quick. In addition, there are high-strength bolts, which have high material strength and can withstand greater tensile and shear forces, making them suitable for structural components requiring high-strength connections.

[0075] In other embodiments, the second mounting bolt can be directly inserted and threaded onto the mounting block 610, so that the second mounting bolt abuts against the microphone 500 in the mounting hole 611. This eliminates the need to divide the mounting block 610 into a first mounting part 612 and a second mounting part 613, and the microphone 500 can still be fixed. Alternatively, the second mounting component 600 can be replaced with a spring, with one end of the spring connected to the first mounting part 612 and the other end connected to the second mounting part 613. This allows the first mounting part 612 and the second mounting part 613 to abut against the microphone 500 using the spring force, thus also fixing the microphone 500.

[0076] The sound leakage detection device also includes a third mounting component 900. At least two third mounting components 900 are provided on each first mounting part 612. The third mounting component 900 is used to pass through or detach from the first mounting part 612 and the bracket 300 to fix or detach the first mounting part 612 from the bracket 300.

[0077] In this embodiment, each first mounting part 612 is provided with two third mounting components 900. The third mounting components 900 are third mounting bolts. The two third mounting bolts are respectively provided at both ends of the first mounting section 616 along the length direction of the bracket 300. The third mounting bolts pass through the first mounting section 616 and are used for insertion and threaded connection to the bracket 300.

[0078] In this application, the use of a third mounting bolt facilitates the disassembly and assembly of the mounting block 610 and the adjustment of the position of the mounting block 610 on the bracket 300. This facilitates the adjustment of the position and number of multiple microphones 500, allowing for a greater detection range and accuracy with different numbers and positions of microphones 500. By removing the unnecessary mounting block 610, the overall weight of the bracket 300 is reduced, making it easier to move the bracket 300.

[0079] In other embodiments, the third mounting component 900 can be a plug-in rod disposed on the first mounting section 616. By plugging the plug-in rod into the bracket 300, the plug-in rod and the bracket 300 are fixed by friction, which can also realize the assembly and disassembly of the mounting block 610.

[0080] The sound leakage detection device also includes at least one cable management tray 230, which is mounted on the support column 200. Multiple cable management holes 231 are provided on the cable management tray 230 along its circumference. The cable management holes 231 are used for the wires of the corresponding pickups 500 to be moved in or out.

[0081] In this embodiment, two cable management trays 230 are provided. One cable management tray 230 is located at the end of the support column 200 away from the base 100, and the cable management tray 230 is located on the side of the support column 200 away from the bracket 300. The other cable management tray 230 is located at the position of the support column 200 close to the base 100, and the cable management tray 230 is sleeved and fixedly connected to the support column 200. The cable management hole 231 is provided through the cable management tray 230 on the side away from the center of the cable management tray 230, so as to facilitate the movement of wires into or out of the cable management hole 231.

[0082] In this application, by adopting the cable management tray 230, when the wires pass through the cable management holes 231 on the two cable management trays 230, they can extend along the height direction of the support column 200, thereby avoiding the tangling and knotting of the wires, making the wiring of multiple microphones 500 more neat and orderly, and facilitating management and maintenance. The cable management tray 230 can fix the wires, reduce the pulling and wear of the wires during use, thereby extending the service life of the wires. Neat wiring can also improve the cleanliness and professionalism of the working environment, reduce safety hazards caused by messy wires, and improve work efficiency and equipment operation reliability.

[0083] The sound leakage detection device provided in this application, by employing a first mounting bolt, allows the second mounting plate 420 to be separated from the clamping plate 800 and the first mounting plate 410, thereby detachably connecting the bracket 300 and the support column 200. When the sound leakage detection device needs to be moved, by removing the bracket 300 from the support column 200, the bracket 300 can pull multiple microphones 500 off, thus facilitating the separate movement of the base 100 and the bracket 300, preventing the heavy weight of the entire sound leakage detection device from making it inconvenient to move, and improving the ease of movement of the sound leakage detection device; by employing the second mounting bolt, multiple microphones 500 can be separated from the bracket 300, allowing multiple... Each microphone 500 is detachably connected to the bracket 300. When the bracket 300 needs to be moved, the microphones 500 can be removed from the bracket 300, making it easier to move the bracket 300 and the microphones 500 individually. This prevents the bracket 300 and the microphones 500 from being too heavy to move and prevents the wires of the microphones 500 from affecting the movement of the bracket 300, thus improving the ease of moving the bracket 300. By using a third mounting bolt, the mounting blocks 610 can be separated from the bracket 300. By removing the unused mounting blocks 610, the weight of the bracket 300 is reduced, making it easier to move the bracket 300.
