[0044] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0045] See Figure 1 An embodiment of the acoustic detection device provided in this application includes a host 10, a first acoustic detection module 20 and a second acoustic detection module 30.

[0046] See Figure 2 and Figure 17 The host 10 is equipped with a display screen 17, which is electrically connected to the first acoustic detection module 20 and the second acoustic detection module 30. The display screen 17 can display the data collected by the first acoustic detection module 20 and the second acoustic detection module 30.

[0047] See Figure 17 The host 10 has a first receiving groove 11 on the side opposite to the display screen 17. Specifically, see [reference needed]. Figure 1 and Figure 17 The first acoustic detection module 20 and the second acoustic detection module 30 are detachably connected. At least a portion of the first acoustic detection module 20 and at least a portion of the second acoustic detection module 30 are disposed in the first receiving groove 11 and are detachably connected to the host 10.

[0048] The first acoustic detection module 20 includes a first housing 21 and a first acoustic detection device. The first housing 21 includes a first mounting surface, and the first acoustic detection device is disposed on the first mounting surface. The second acoustic detection module 30 includes a second housing 31 and a second acoustic detection device. The second housing 31 includes a second mounting surface, and the second acoustic detection device is disposed on the second mounting surface. The area of ​​the first mounting surface is larger than the area of ​​the second mounting surface.

[0049] Optionally, both the first outer shell 21 and the second outer shell 31 are square structures.

[0050] In its initial state, at least a portion of the first acoustic detection module 20 and at least a portion of the second acoustic detection module 30 are disposed within the first receiving slot 11 and connected to the host 10. Thus, the acoustic detection device in its initial state can detect sound sources within a relatively large space.

[0051] Since both the first acoustic detection module 20 and the second acoustic detection module 30 are detachably connected to the host 10, they can be removed from the first receiving slot 11, thus separating them from the host 10. This allows the first acoustic detection module 20 and the second acoustic detection module 30 to extend into a narrow space to detect sound sources within that space.

[0052] Since the area of ​​the second mounting surface is smaller than that of the first mounting surface, and the first acoustic detection module 20 and the second acoustic detection module 30 can be detachably connected, the second acoustic detection module 30 can be removed from the first receiving groove 11, thus separating the second acoustic detection module 30 from the first acoustic detection module 20. This allows the second acoustic detection module 30 to extend into a narrower space to detect sound sources in a narrower space.

[0053] The acoustic detection device described above can detect sound sources not only in large spaces, but also in various narrow spaces, thus expanding the applicability of the acoustic detection device.

[0054] In one embodiment, see Figure 1 The first acoustic detection device includes a first microphone 22 and a first camera 23. Multiple first microphones 22 are provided, and an array of multiple first microphones 22 is arranged. The second acoustic detection device includes a second microphone 32 and a second camera 33. Multiple second microphones 32 are provided, and an array of multiple second microphones 32 is arranged. The first camera 23 is located in the middle of the area where the first mounting surface and the second mounting surface are located, and the second camera 33 is located in the middle of the second mounting surface. This improves the accuracy of the detection.

[0055] In one embodiment, see Figure 3 , Figure 4 and Figure 17 The acoustic testing device also includes a first mounting base 40 and a second mounting base 50. The first mounting base 40 is disposed in the first receiving groove 11 and is detachably connected to the main unit 10, and the first acoustic testing module 20 is disposed on the first mounting base 40.

[0056] See Figure 3 and Figure 18 The first mounting base 40 is provided with a second receiving groove 41, the area of ​​which is less than half the area of ​​the first mounting base 40. A second mounting base 50 is disposed within the second receiving groove 41 and is detachably connected to the first mounting base 40. The second acoustic detection module 30 is disposed on the second mounting base 50. For details, please refer to... Figure 4The first acoustic detection module 20 and the second acoustic detection module 30 are arranged side by side in a first direction, denoted by S. By providing a first mounting base 40 and a second mounting base 50, the first mounting base 40 provides a mounting position for the first acoustic detection module 20, and the second mounting base 50 provides a mounting position for the second acoustic detection module 30, etc.

[0057] To detect a sound source in a narrow space, the first mounting base 40 and its second mounting base 50, the first acoustic detection module 20, and the second acoustic detection module 30 are removed from the first receiving slot 11, so that the first mounting base 40, the second mounting base 50, the first acoustic detection module 20, and the second acoustic detection module 30 are all separated from the host 10. In this way, the first acoustic detection module 20 and the second acoustic detection module 30 can be inserted into the narrow space to detect the sound source in the narrow space.

[0058] If a sound source in a more confined space is to be detected, the second mounting base 50 is removed from the second receiving slot 41, so that the second mounting base 50 is separated from the first mounting base 40. In this way, the second acoustic detection module 30 can be extended into the more confined space to detect the sound source in the more confined space.

[0059] In one embodiment, see Figure 4 and Figure 6 The acoustic detection device also includes a first locking assembly 60. The first locking assembly 60 is located between the main unit 10 and the first mounting base 40, allowing the main unit 10 and the first mounting base 40 to be detachably connected. When detecting sound sources in a large space, the first locking assembly 60 locks the first mounting base 40 to the main unit 10, preventing the first mounting base 40 from shaking and improving the reliability of the acoustic detection device. When detecting sound sources in a narrow space, the first locking assembly 60 is released from the first mounting base 40, allowing the first mounting base 40 to be removed from the first receiving slot 11, facilitating the detection of sound sources in narrow spaces by the first acoustic detection module 20 and the second acoustic detection module 30.

[0060] In one embodiment, see Figure 17 The first receiving groove 11 has a first mounting groove 12 on its wall, and the first mounting groove 12 communicates with the first receiving groove 11. (See reference...) Figure 6 The first mounting base 40 is provided with a first limiting part 42.

[0061] Further, see Figure 6The first lock assembly 60 includes a first actuating member 61, which is movably disposed within a first mounting groove 12. The first actuating member 61 has a second limiting portion 611. Optionally, the first actuating member 61 is rod-shaped, with the second limiting portion 611 at one end and the other end outside the first mounting groove 12. The first actuating member 61 can move within the first mounting groove 12 to give the first lock assembly 60 a first locked state and a first unlocked state. In the first locked state, the first limiting portion 42 and the second limiting portion 611 are engaged; in the first unlocked state, the first limiting portion 42 and the second limiting portion 611 are disengaged.

[0062] When detecting sound sources in a large space, the first limiting part 42 and the second limiting part 611 cooperate to lock the first mounting base 40 to the main unit 10, preventing the acoustic detection device from shaking and improving the reliability of the acoustic detection device.

[0063] When detecting a sound source in a confined space, an external force is applied to the first actuating member 61, causing it to move within the first mounting groove 12, thus switching the first locking assembly 60 from a first locked state to a first unlocked state. In the first unlocked state, the first limiting part 42 separates from the second limiting part 611, allowing the first mounting base 40 to be removed from the first receiving groove 11, thereby separating the first acoustic detection module 20 and the second acoustic detection module 30 from the main unit 10.

[0064] In one embodiment, see Figure 6 and Figure 18 The first limiting part 42 is provided with a first limiting groove 421, and the second limiting part 611 is provided with a first limiting block 6111. Optionally, the first limiting groove 421 is hemispherical, and the first limiting block 6111 is spherical. In the first locked state, the first limiting block 6111 is disposed within the first limiting groove 421. In the first unlocked state, the first limiting block 6111 is separated from the first limiting groove 421. Thus, through the cooperation of the first limiting groove 421 and the first limiting block 6111, the first mounting base 40 and the main unit 10 can be quickly locked and unlocked.

[0065] Of course, in other embodiments, the first limiting part 42 is provided with a first magnetic attracting member, and the second limiting part 611 is provided with a second magnetic attracting member. In the first locked state, the first magnetic attracting member and the second magnetic attracting member are magnetically attracted to each other; in the first unlocked state, the first magnetic attracting member and the second magnetic attracting member are separated.

[0066] In one embodiment, see Figure 6 and Figure 7The first actuating member 61 is rotatably disposed within the first mounting groove 12. Optionally, a first rotating member 62 is provided at the middle of the first actuating member 61 along its length, and the first rotating member 62 is rotatably connected to the groove wall of the first mounting groove 12.

[0067] Further, see Figure 6 and Figure 7 The first locking assembly 60 also includes a first elastic element 63, which drives the first actuating element 61 to move so that the first limiting part 42 and the second limiting part 611 are engaged in a limiting engagement. When the first mounting base 40 is fully inserted into the first receiving groove 11, the first actuating element 61 moves under the action of the first elastic element 63, so that the first limiting part 42 and the second limiting part 611 are engaged in a limiting engagement, thereby locking the first mounting base 40 onto the main unit 10.

[0068] Optionally, the first elastic element 63 is a spiral spring. The spiral spring is sleeved on the first rotating element 62, with one end located on the inner side of the spiral spring connected to the first rotating element 62, and the other end located on the outer side of the spiral spring connected to the main unit 10.

[0069] In one embodiment, see Figure 6 The first mounting groove 12 has a first sliding groove 16 on its wall, which communicates with the first receiving groove 11. The first sliding groove 16 is arc-shaped, and the second limiting part 611 is movably disposed within the first sliding groove 16. In the first unlocked state, the second limiting part 611 can move within the first sliding groove 16, and the first sliding groove 16 can guide the movement of the second limiting part 611, thereby improving the reliability of locking and unlocking.

[0070] In one embodiment, see Figure 8 The acoustic detection device also includes a second locking assembly 70. The second locking assembly 70 is located between the first mounting base 40 and the second mounting base 50, allowing the first mounting base 40 and the second mounting base 50 to be detachably connected. When detecting sound sources in a larger space, the second locking assembly 70 locks the second mounting base 50 to the first mounting base 40, preventing the second mounting base 50 from shaking and improving the reliability of the acoustic detection device. When detecting sound sources in a more confined space, the second locking assembly 70 is released from the second mounting base 50, allowing the second mounting base 50 to be removed from the second receiving slot 41, facilitating the detection of sound sources in even more confined spaces by the second acoustic detection module 30.

[0071] In one embodiment, see Figure 18 The second receiving groove 41 has a second mounting groove 44 on its groove wall, and the second mounting groove 44 communicates with the second receiving groove 41. (See reference...) Figure 9 and Figure 19 The second mounting base 50 is provided with a third limiting part 51.

[0072] Further, see Figure 9 The second locking assembly 70 includes a second actuating member 71, which is movably disposed within the second mounting groove 44. The second actuating member 71 has a fourth limiting portion 711. Optionally, the second actuating member 71 is rod-shaped, with the fourth limiting portion 711 at one end and the other end outside the second mounting groove 44. The second actuating member 71 can move within the second mounting groove 44 to give the second locking assembly 70 a second locked state and a second unlocked state. In the second locked state, the third limiting portion 51 and the fourth limiting portion 711 are engaged; in the second unlocked state, the third limiting portion 51 and the fourth limiting portion 711 are disengaged.

[0073] When detecting sound sources in a large space, the third limiting part 51 and the fourth limiting part 711 cooperate to lock the second mounting base 50 to the first mounting base 40, preventing the second acoustic detection module 30 from shaking, which helps to improve the reliability of the acoustic detection device.

[0074] When detecting a sound source in a confined space, an external force is applied to the second actuating member 71, causing it to move within the second mounting groove 44. This switches the second locking assembly 70 from a second locked state to a second unlocked state. In the second unlocked state, the third limiting part 51 separates from the fourth limiting part 711, allowing the second mounting base 50 to be removed from the second receiving groove 41. This separates the second acoustic detection module 30 and the second mounting base 50 from the first mounting base 40, enabling the second acoustic detection module 30 to extend into the confined space to detect sound sources within it.

[0075] In one embodiment, see Figure 9 and Figure 19 The third limiting part 51 is provided with a second limiting groove 511, and the fourth limiting part 711 is provided with a second limiting block 7111. Optionally, the second limiting groove 511 is a hemispherical groove, and the second limiting block 7111 is a spherical block. In the second locked state, the second limiting block 7111 is disposed within the second limiting groove 511. In the second unlocked state, the second limiting block 7111 is separated from the second limiting groove 511. Thus, through the cooperation of the second limiting groove 511 and the second limiting block 7111, the first mounting base 40 and the second mounting base 50 can achieve rapid locking and unlocking.

[0076] Of course, in other embodiments, the third limiting part 51 is provided with a third magnetic attracting member, and the fourth limiting part 711 is provided with a fourth magnetic attracting member. In the second locked state, the third magnetic attracting member and the fourth magnetic attracting member are magnetically attracted to each other; in the second unlocked state, the third magnetic attracting member and the fourth magnetic attracting member are separated.

[0077] In one embodiment, see Figure 9 and Figure 10 The second actuating member 71 is rotatably disposed within the second mounting groove 44. Specifically, a second rotating member 72 is provided at the middle of the length direction of the second actuating member 71, and the second rotating member 72 is rotatably connected to the groove wall of the second mounting groove 44.

[0078] Further, see Figure 10 The second locking assembly 70 also includes a second elastic member 73, which drives the second actuating member 71 to move so that the third limiting part 51 and the fourth limiting part 711 are engaged in a limiting engagement. When the second mounting base 50 is fully inserted into the second receiving groove 41, the second actuating member 71 moves under the action of the second elastic member 73 so that the third limiting part 51 and the fourth limiting part 711 are engaged in a limiting engagement, thereby locking the second mounting base 50 in the second receiving groove 41.

[0079] Optionally, the second elastic element 73 is a spiral spring. The spiral spring is sleeved on the second rotating element 72, with one end located on the inner side of the spiral spring connected to the second rotating element 72, and the other end located on the outer side of the spiral spring connected to the first mounting base 40.

[0080] In one embodiment, see Figure 9 The second mounting groove 44 has a second sliding groove 43 on its wall, which communicates with the second receiving groove 41. The second sliding groove 43 is arc-shaped, and the fourth limiting part 711 is movably disposed within the second sliding groove 43. In the second unlocked state, the fourth limiting part 711 can move within the second sliding groove 43, and the second sliding groove 43 can guide the movement of the fourth limiting part 711, thereby improving the reliability of locking and unlocking.

[0081] In one embodiment, see Figure 3 and Figure 4 The first acoustic detection module 20 also includes a first chip 24, which is electrically connected to the first acoustic detection device. The second acoustic detection module 30 also includes a second chip 34, which is electrically connected to the second acoustic detection device.

[0082] Further, see Figure 4 The acoustic detection device also includes a control component 14, which is located on the main unit 10. The control component 14 is electrically connected to one of the first chip 24 and the second chip 34 via a first cable 84. The first chip 24 is electrically connected to the second chip 34 via a second cable 94.

[0083] In one embodiment, see Figure 3 The acoustic detection device also includes a first pulley assembly 80. The first pulley assembly 80 is located on the main unit 10. Specifically, see [link to documentation]. Figure 8The main unit 10 is also provided with a first receiving cavity 13, and the first pulley assembly 80 is disposed in the first receiving cavity 13.

[0084] Further, see Figure 11 and Figure 12 The first pulley assembly 80 includes a first fixed pulley 81 and a first movable pulley 82. Both the first fixed pulley 81 and the first movable pulley 82 are located on the cavity wall of the first receiving cavity 13. The first movable pulley 82 can move towards or away from the first fixed pulley 81. A first cable 84 is wound around the first fixed pulley 81 and the first movable pulley 82. Optionally, the first movable pulley 82 can move along a first direction. To detect a sound source in a narrow space, the first mounting base 40 and the first acoustic detection module 20 and the second acoustic detection module 30 mounted thereon are removed from the first receiving groove 11. During removal, one end of the first cable 84 connected to one of the first chip 24 and the second chip 34 drives the first movable pulley 82 towards the first fixed pulley 81. This provides sufficient extension and retraction of the first cable 84, ensuring that the first mounting base 40 can be smoothly removed from the first receiving groove 11.

[0085] In one embodiment, see Figure 11 Multiple first fixed pulleys 81 are provided, arranged side by side and spaced apart. At least two first movable pulleys 82 are provided, with one first movable pulley 82 corresponding to each of two adjacent first fixed pulleys 81. In this embodiment, there are three first fixed pulleys 81, and two first fixed pulleys 81 are provided.

[0086] In one embodiment, see Figure 11 The cavity wall of the first receiving cavity 13 is provided with a first guide groove 15, which extends along a first direction.

[0087] Further, see Figure 11 and Figure 12 The first pulley assembly 80 also includes a first wheel seat 83, on which a first movable pulley 82 is disposed. The first wheel seat 83 has a first guide block 831 disposed within a first guide groove 15. Thus, the first wheel seat 83 provides an installation position for the first movable pulley 82, facilitating its installation within the first receiving cavity 13. Furthermore, the cooperation between the first guide block 831 and the first guide groove 15 ensures directional movement of the first wheel seat 83, improving the smoothness of its movement and consequently enhancing the ease of winding and unwinding the first cable 84.

[0088] Optionally, the first guide groove 15 is trapezoidal, and the first guide block 831 is trapezoidal.

[0089] In one embodiment, see Figure 11 and Figure 12The acoustic detection device also includes a third elastic element 85. The third elastic element 85 is disposed within the first receiving cavity 13 and is capable of extending and retracting along a first direction. One end of the third elastic element 85 is connected to the cavity wall of the first receiving cavity 13, and the other end is connected to the first wheel seat 83. During the process of removing the first mounting seat 40 from the first receiving groove 11, the first wheel seat 83 moves towards the first fixed pulley 81, thereby stretching the third elastic element 85. When the first mounting seat 40 is assembled into the first receiving groove 11, the third elastic element 85 gradually recovers its deformation, thereby causing the first wheel seat 83 to move away from the first fixed pulley 81, thus driving the first cable 84 to be wound up.

[0090] In one embodiment, see Figure 3 The acoustic detection device also includes a second pulley assembly 90. The second pulley assembly 90 is disposed on the first mounting base 40. Specifically, see [link to relevant documentation]. Figure 8 The first mounting base 40 is provided with a second receiving cavity 45, and the second pulley assembly 90 is disposed within the second receiving cavity 45. In this way, the second pulley assembly 90 is hidden within the second receiving cavity 45, avoiding external interference to the second pulley assembly 90 and ensuring the reliability of the operation of the second pulley assembly 90.

[0091] Further, see Figure 13 and Figure 14 The second pulley assembly 90 includes a second fixed pulley 91 and a second movable pulley 92. Both the second fixed pulley 91 and the second movable pulley 92 are disposed on the cavity wall of the second receiving cavity 45. The second movable pulley 92 is movable towards or away from the second fixed pulley 91. Optionally, the second movable pulley 92 is movable in a first direction. The second cable 94 passes around the second fixed pulley 91 and the second movable pulley 92.

[0092] If the sound source is to be detected in a more confined space, the second mounting base 50 is removed from the second receiving slot 41. During the removal process, the end of the second cable 94 connected to the second chip 34 drives the second movable pulley 92 to move towards the second fixed pulley 91. This gives the second cable 94 sufficient extension and retraction, ensuring that the second mounting base 50 can be smoothly removed from the second receiving slot 41.

[0093] In one embodiment, see Figure 13 Multiple second fixed pulleys 91 are provided, arranged side by side and spaced apart. At least two second movable pulleys 92 are provided, with one second movable pulley 92 corresponding to each two adjacent second fixed pulleys 91. In this embodiment, there are three second fixed pulleys 91, and two second fixed pulleys 91 are provided.

[0094] In one embodiment, see Figure 13The cavity wall of the second receiving cavity 45 is provided with a second guide groove 46, which extends along the first direction.

[0095] Further, see Figure 13 and Figure 14 The second pulley assembly 90 also includes a second wheel seat 93, on which the second movable pulley 92 is disposed. The second wheel seat 93 is provided with a second guide block 931, which is disposed within a second guide groove 46. Thus, the second wheel seat 93 provides an installation position for the second movable pulley 92, facilitating its installation within the second receiving cavity 45. Furthermore, the cooperation between the second guide block 931 and the second guide groove 46 ensures directional movement of the second wheel seat 93 and the second movable pulley 92, improving the smoothness of their movement and consequently enhancing the ease of retracting and extending the second cable 94.

[0096] Optionally, the second guide groove 46 is trapezoidal, and the second guide block 931 is trapezoidal.

[0097] In one embodiment, see Figure 13 and Figure 14 The acoustic detection device also includes a fourth elastic element 95. The fourth elastic element 95 is disposed within the second receiving cavity 45 and is capable of extending and retracting along a first direction. One end of the fourth elastic element 95 is connected to the cavity wall of the second receiving cavity 45, and the other end is connected to the second wheel seat 93. During the removal of the second mounting seat 50 from the second receiving groove 41, the second wheel seat 93 moves towards the second fixed pulley 91, thereby stretching the fourth elastic element 95. When the second mounting seat 50 is assembled into the second receiving groove 41, the fourth elastic element 95 gradually recovers its deformation, thereby causing the second wheel seat 93 to move away from the second fixed pulley 91, thus driving the second cable 94 to be wound up.

[0098] In one embodiment, see Figure 4 , Figure 5 and Figure 20 The first mounting surface is positioned away from the first mounting base 40, and the first mounting surface is provided with a first socket 211 and a second socket 214.

[0099] The first microphone 22 is housed within the first jack 211, and the first camera 23 is housed within the second jack 214. By integrating the first microphone 22 into the first jack 211 and the first camera 23 into the second jack 214, the first acoustic detection module 20 achieves a compact structure, which is beneficial for miniaturization. Furthermore, the first microphone 22 can capture ambient sound signals through the first jack 211, and the first camera 23 can acquire visual image information through the second jack 214, thus improving the richness and accuracy of data acquisition.

[0100] In one embodiment, the first housing 21 further includes a third mounting surface, which is disposed near the first mounting base 40. The third mounting surface is provided with a first sliding hole 212 and a second sliding hole 215, the first sliding hole 212 being disposed opposite to the first insertion hole 211, and the second sliding hole 215 being disposed opposite to the second insertion hole 214.

[0101] See Figure 5 The first acoustic detection module 20 also includes a first support member 25 and a second support member 26. Both the first support member 25 and the second support member 26 are disposed inside the first housing 21. One end of the first support member 25 is slidably disposed in the first sliding hole 212 and is sealed to the hole wall of the first sliding hole 212. The first support member 25 is connected to the first mounting base 40, and the other end of the first support member 25 is connected to the first microphone 22.

[0102] See Figure 5 One end of the second support member 26 is slidably disposed in the second sliding hole 215 and is sealed to the hole wall of the second sliding hole 215. The second support member 26 is connected to the first mounting base 40, and the other end of the second support member 26 is connected to the first camera 23.

[0103] If it is necessary to clean the first microphone 22, the first camera 23, the first jack 211, and the second jack 214, an external force is applied to the first housing 21, causing the first housing 21 to move away from the first mounting base 40. This causes the first microphone 22 to exit the first jack 211 and the first camera 23 to exit the second jack 214. In this way, external air can enter the first housing 21 through the first jack 211 and the second jack 214. Under the action of the airflow, the impurities in the first microphone 22, the first camera 23, the first jack 211, and the second jack 214 can be cleaned.

[0104] In one embodiment, see Figure 5 The first mounting surface is provided with a first conical sleeve 216 and a second conical sleeve 217, both of which are located inside the first outer shell 21. The first conical sleeve 216 corresponds to and communicates with the first socket 211, and is fitted onto the first microphone 22. The second conical sleeve 217 corresponds to and communicates with the second socket 214, and is fitted onto the first camera 23.

[0105] See Figure 5The first support member 25 is provided with a first conical cover 251, and a first conical sleeve 216 is disposed inside the first conical cover 251. The second support member 26 is provided with a second conical cover 261, and a second conical sleeve 217 is disposed inside the second conical cover 261. With the cooperation of the first conical sleeve 216 and the first conical cover 251, the first microphone 22 can be quickly and accurately inserted into the first jack 211. With the cooperation of the second conical sleeve 217 and the second conical cover 261, the first camera 23 can be quickly and accurately inserted into the second jack 214.

[0106] In one embodiment, see Figure 4 , Figure 5 and Figure 21 The second mounting surface is positioned away from the second mounting base 50, and the second mounting surface is provided with a third socket 311 and a fourth socket 314.

[0107] The second microphone 32 is housed within the third jack 311, and the second camera 33 is housed within the fourth jack 314. By integrating the second microphone 32 into the third jack 311 and the second camera 33 into the fourth jack 314, the second acoustic detection module 30 achieves a compact structure, which is beneficial for miniaturization. Furthermore, the second microphone 32 can capture ambient sound signals through the third jack 311, and the second camera 33 can acquire visual image information through the fourth jack 314, thus improving the richness and accuracy of data acquisition.

[0108] In one embodiment, the second housing 31 further includes a fourth mounting surface disposed near the second mounting base 50. The fourth mounting surface is provided with a third sliding hole 312 and a fourth sliding hole 315, the third sliding hole 312 being disposed opposite to the third insertion hole 311, and the fourth sliding hole 315 being disposed opposite to the fourth insertion hole 314.

[0109] See Figure 5 The second acoustic detection module 30 also includes a third support member 35 and a fourth support member 36, both of which are located within the second housing 31. One end of the third support member 35 is slidably disposed within a third sliding hole 312 and is sealed to the wall of the third sliding hole 312. The third support member 35 is connected to the second mounting base 50, and the other end of the third support member 35 is connected to the second microphone 32.

[0110] See Figure 5 One end of the fourth support member 36 is movably disposed in the fourth sliding hole 315 and is sealed to the hole wall of the fourth sliding hole 315. The fourth support member 36 is connected to the second mounting base 50, and the other end of the fourth support member 36 is connected to the second camera 33.

[0111] If it is necessary to clean the impurities from the second microphone 32, the second camera 33, the third jack 311, and the fourth jack 314, an external force is applied to the second housing 31, causing the second housing 31 to move away from the second mounting base 50. This causes the second microphone 32 to exit the third jack 311 and the second camera 33 to exit the fourth jack 314. In this way, external air can enter the second housing 31 through the third jack 311 and the fourth jack 314. Under the action of the airflow, the impurities from the second microphone 32, the second camera 33, the third jack 311, and the fourth jack 314 can be cleaned.

[0112] In one embodiment, see Figure 5 The second mounting surface is provided with a third conical sleeve 316 and a fourth conical sleeve 317, both of which are located inside the second outer shell 31. The third conical sleeve 316 corresponds to and communicates with the third socket 311, and is fitted onto the second microphone 32. The fourth conical sleeve 317 corresponds to and communicates with the fourth socket 314, and is fitted onto the second camera 33.

[0113] Furthermore, the third support member 35 is provided with a third conical cover 351, and a third conical sleeve 316 is disposed inside the third conical cover 351. One end of the fourth support member 36 is provided with a fourth conical cover 361, and a fourth conical sleeve 317 is disposed inside the fourth conical cover 361. With the cooperation of the third conical sleeve 316 and the fourth conical cover 361, the second microphone 32 can be quickly and accurately inserted into the third jack 311. With the cooperation of the third conical sleeve 316 and the fourth conical cover 361, the second camera 33 can be quickly and accurately inserted into the fourth jack 314.

[0114] In one embodiment, the first housing 21 and the second housing 31 can be detachably connected. Optionally, the first housing 21 is provided with a retaining strip 28, and the second housing 31 is provided with a retaining groove 38, with the retaining strip 28 disposed in the retaining groove 38.

[0115] Furthermore, the acoustic testing device also includes an air pump 110, which is located in the main unit 10. The air pump 110 has an air intake port, which is connected to the first housing 21 and the second housing 31.

[0116] Optionally, see Figure 3The first outer casing 21 is provided with a first connecting hole 213, and the second outer casing 31 is provided with a second connecting hole 313, with the first connecting hole 213 communicating with the second connecting hole 313. The acoustic detection device also includes an air intake pipe 120, one end of which is connected to an air intake port, and the other end of which is connected to one of the first outer casing 21 and the second outer casing 31. The air intake pipe 120 is a retractable corrugated pipe; alternatively, the air intake pipe 120 includes at least two pipe bodies nested together, so that the length of the air intake pipe 120 is adjustable, ensuring that the first acoustic detection module 20 and the second acoustic detection module 30 can be separated from the main unit 10.

[0117] Optionally, the acoustic detection device further includes a first suction pipe 120 and a second suction pipe 120. One end of the first suction pipe 120 is connected to the first housing 21, one end of the second suction pipe 120 is connected to the second housing 31, and the other ends of both the first and second suction pipes 120 are connected to the suction port.

[0118] During cleaning, external force is applied to the first housing 21 and the second housing 31. The first housing 21 moves away from the first mounting base 40, causing the first microphone 22 to exit the first jack 211 and the first camera 23 to exit the second jack 214. At the same time, the second housing 31 moves away from the second mounting base 50, causing the second microphone 32 to exit the third jack 311 and the second camera 33 to exit the fourth jack 314. Then, the air pump 110 is activated, creating negative pressure inside the first housing 21 and the second housing 31. Under this negative pressure, external air enters the first housing 21 through the first socket 211 and the second socket 214, thus drawing in and collecting the dust accumulated in the first socket 211, the second socket 214, the first microphone 22, and the first camera 23. Simultaneously, external air enters the second housing 31 through the third socket 311 and the fourth socket 314, drawing in and collecting the dust accumulated in the third socket 311, the fourth socket 314, the second microphone 32, and the second camera 33. After cleaning, the dust inside the first housing 21 and the second housing 31 is cleaned. Thus, during the cleaning process, the first microphone 22 and the second microphone 32 are not impacted by the airflow, preventing damage to them.

[0119] In one embodiment, the first housing 21 includes a first housing adjacent to the first mounting base 40 and a second housing opposite to the first mounting base 40, the first housing and the second housing being detachably connected. This allows the first housing and the second housing to be separated, facilitating the cleaning of impurities inside the first housing 21.

[0120] Furthermore, the second housing 31 includes a third housing adjacent to the second mounting base 50 and a fourth housing opposite to the second mounting base 50, the third housing and the fourth housing being detachably connected. This allows the third housing to be separated, facilitating the cleaning of impurities inside the second housing 31.

[0121] In one embodiment, see Figure 3 The acoustic detection device also includes a filter assembly 130, which is located at the end of the suction pipe 120 away from the air pump 110. In this way, the filter assembly 130 filters impurities in the first housing 21 and the second housing 31 before passing them through the suction pipe 120, thus preventing impurities from clogging the suction pipe 120.

[0122] In one embodiment, see Figure 16 The acoustic detection device also includes a drive element 100. Optionally, the drive element 100 is an electric actuator. The drive element 100 is connected to at least one of the first housing 21 and the second housing 31, and the drive element 100 is used to drive the first housing 21 and the second housing 31 to move in a direction away from the first mounting base 40. During the cleaning of impurities, the drive element 100 can drive the first housing 21 and the second housing 31 to move in a direction away from the first mounting base 40.

[0123] Further, see Figure 18 The first mounting base 40 is provided with a clearance groove 47, and the drive component 100 is disposed in the clearance groove 47 and connected to the first housing 21. In this way, the clearance groove 47 can play a role in avoiding interference with the installation of the drive component 100.

[0124] In one embodiment, see Figure 15 At least one of the first support member 25 and the second support member 26 is connected to a fifth elastic member 27. The other end of the fifth elastic member 27 is connected to the first housing 21, and the fifth elastic member 27 is used to drive the first housing 21 to reset. Optionally, the first support member 25 is provided with a first compression spring ring 252, one end of the fifth elastic member 27 is connected to the first compression spring ring 252, and the other end of the fifth elastic member 27 is connected to the third mounting surface. During the movement of the first housing 21 away from the first mounting base 40, the fifth elastic member 27 is gradually compressed. After cleaning, the fifth elastic member 27 restores its deformation, and the first housing 21 resets under the action of the fifth elastic member 27, so that the third mounting surface fits against the first mounting base 40, the first microphone 22 is inserted into the first jack 211, and the first camera 23 is inserted into the second jack 214.

[0125] Optionally, the fifth elastic element 27 is a spring, which is sleeved on the first support element 25. In this way, the first support element 25 can guide the extension and contraction of the spring, thereby improving the stability of the spring's extension and contraction.

[0126] In one embodiment, see Figure 15 At least one of the third support member 35 and the fourth support member 36 is connected to a sixth elastic member 37. The other end of the sixth elastic member 37 is connected to the second housing 31, and the sixth elastic member 37 is used to drive the second housing 31 to reset. Optionally, the third support member 35 is provided with a second compression spring ring 352. One end of the sixth elastic member 37 is connected to the second compression spring ring 352, and the other end of the sixth elastic member 37 is connected to the fourth mounting surface. As the second housing 31 moves away from the second mounting base 50, the sixth elastic member 37 is gradually compressed. After cleaning, the sixth elastic member 37 returns to its original shape, and the second housing 31 resets under the action of the sixth elastic member 37, so that the fourth mounting surface fits against the second mounting base 50, the second microphone 32 is inserted into the third jack 311, and the second camera 33 is inserted into the fourth jack 314.

[0127] Optionally, the sixth elastic element 37 is a spring, which is sleeved on the third support element 35. In this way, the third support element 35 can guide the extension and contraction of the spring, thereby improving the stability of the spring's extension and contraction.

[0128] In one embodiment, see Figure 3 and Figure 20 The first mounting surface is also provided with a first conical hole 218. The first conical hole 218 is located on the side of the first insertion hole 211 away from the first mounting base 40 and communicates with the first insertion hole 211. The small end of the first conical hole 218 is connected to the hole wall of the first insertion hole 211. In this way, the first conical hole 218 can effectively collect sound waves.

[0129] In one embodiment, see Figure 3 and Figure 20 The first mounting surface is also provided with a second conical hole 219. The second conical hole 219 is located on the side of the second insertion hole 214 away from the first mounting base 40 and communicates with the second insertion hole 214. The small end of the second conical hole 219 is connected to the hole wall of the second insertion hole 214. In this way, the field of view of the first camera 23 can be expanded by the action of the second conical hole 219.

[0130] In one embodiment, see Figure 3 and Figure 21 The second mounting surface is also provided with a third conical hole 318. The third conical hole 318 is located on the side of the third insertion hole 311 away from the second mounting base 50 and communicates with the third insertion hole 311. The small end of the third conical hole 318 is connected to the hole wall of the third insertion hole 311. In this way, the sound waves can be effectively collected by the action of the third conical hole 318.

[0131] In one embodiment, see Figure 3 and Figure 21The second mounting surface is also provided with a fourth conical hole 319. The fourth conical hole 319 is located on the side of the fourth insertion hole 314 opposite to the second mounting base 50 and communicates with the fourth insertion hole 314. The small end of the fourth conical hole 319 is connected to the hole wall of the fourth insertion hole 314. In this way, the field of view of the second camera 33 can be expanded by the action of the fourth conical hole 319.

[0132] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0133] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0134] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0135] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0136] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element.
