Abstract
Description
Technical Field
[0001] This utility model relates to the field of acoustic analysis technology, and in particular to an acoustic characteristic analyzer. Background Technology
[0002] Acoustic analyzers are widely used in acoustic signal acquisition, noise measurement, and environmental acoustic analysis. Existing acoustic analyzers typically use a fixed support for measurement, but fixed support equipment lacks stability in complex environments and is affected by factors such as uneven ground and external vibrations, leading to fluctuations in measurement results.
[0003] To address the aforementioned issues, existing technologies have proposed a triangular support structure to stably mount the acoustic analysis head on the substrate, thereby reducing external interference and improving measurement accuracy. However, relying solely on a tripod structure is still insufficient to completely eliminate vibration interference, especially in scenarios with uneven ground or significant external disturbances, where the equipment may still tilt or sway, affecting data accuracy. Therefore, how to further optimize the stability of the acoustic analyzer to adapt to different scenarios and effectively reduce the impact of external vibration on measurement accuracy is a pressing issue that needs to be addressed in current technology.
[0004] Therefore, we propose an acoustic characteristic analyzer to solve the existing problems. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an acoustic characteristic analyzer.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an acoustic characteristic analyzer, comprising a substrate, a mass block, an acoustic analysis head, and a pressing assembly, wherein the acoustic analysis head is disposed on the substrate, a main shaft is rotatably disposed on the substrate, and the pressing assembly is disposed below the substrate, the pressing assembly being used for friction positioning of the main shaft.
[0007] The mass block is mounted on the main shaft via a translation component, which is used to control the positional distance between the mass block and the main shaft.
[0008] Preferably, the pressing assembly consists of a paddle, a screw housing, a friction block, a shaft head block, and a screw seat. The screw seat is disposed on the lower surface of the base plate, the screw housing is threaded onto the screw seat, and the friction block is rotatably disposed at the central axis of the screw housing.
[0009] Preferably, the shaft head block is located at the bottom end of the main shaft, the friction block presses tightly against the shaft head block, and the pawl is located on the outer wall of the screw shell.
[0010] Preferably, the translation assembly consists of a connecting seat, a screw, a cap block, and a screw block. The connecting seat is mounted on the main shaft, the screw is rotatably mounted on the connecting seat, and the cap block is mounted on the other end of the screw.
[0011] Preferably, the screw block is threaded onto the screw rod, and the two mass blocks are symmetrically arranged on both sides of the screw block, with the lower mass block sliding in contact with the upper surface of the substrate.
[0012] Preferably, the screw block has a screw hole adapted to the screw rod, and the screw rod is threaded onto the screw hole.
[0013] Preferably, the outer wall of the acoustic analysis head is provided with a ring, and the outer wall of the ring is provided with legs at equal intervals, the bottom end of the legs being located on the upper surface of the substrate.
[0014] Preferably, the lower surface of the substrate is provided with four support seats, and the four support seats are arranged in a rectangular array on the lower surface of the substrate.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] In use, the acoustic analysis head of this utility model is mounted on the base plate via a triangular support leg. The acoustic analysis head analyzes the acoustic characteristics. In addition, the design of the adjustable mass block position, in addition to the tripod, includes an adjustable center of gravity base, thereby enhancing the stability of the device in different scenarios.
[0017] When adjusting the position of the mass block, the translation component works, thereby moving the mass block closer to or away from the spindle, increasing or decreasing the moving radius of the mass block. At the same time, the operator can manually rotate the spindle to move the mass block in a circular motion. When the mass block moves to the designated position, the pressure component works to position the spindle, thereby limiting the mass block.
[0018] When the translation component is working, manually rotating the cap block drives the screw to rotate. Through the threaded engagement between the screw block and the screw, and at this time the screw block is constrained by the mass block and does not deflect, the rotation of the screw is converted into the translation of the mass block under the principle of the lead screw.
[0019] When the pressure component is working, the operator manually rotates the screw housing using a lever. The threaded engagement between the screw housing and the screw seat causes the friction block to press against the surface of the shaft head block. Under the action of strong friction, the spindle is prevented from rotating.
[0020] This invention features an adjustable mass block base. By adjusting the position of the mass block, the center of gravity of the device is changed, allowing it to adapt to different terrains, reducing the impact of tilting or swaying, improving the environmental adaptability of the acoustic characteristic analyzer, enhancing the stability of the device, and thus ensuring that high-precision acoustic measurement data can be obtained in different measurement scenarios.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1
[0029] like Figures 1-4As shown, the acoustic characteristic analyzer proposed in this utility model includes a substrate 1, a mass block 3, an acoustic analysis head 8, and a pressing component 9. The acoustic analysis head 8 is mounted on the substrate 1, and a ring 7 is provided on the outer wall of the acoustic analysis head 8. Support legs 6 are provided at equal intervals on the outer wall of the ring 7, and the bottom ends of the support legs 6 are located on the upper surface of the substrate 1. A main shaft 5 is rotatably mounted on the substrate 1. The pressing component 9 is located below the substrate 1 and is used to rub and position the main shaft 5. The mass block 3 is mounted on the main shaft 5 through a translation component 4, which is used to control the positional distance between the mass block 3 and the main shaft 5. The acoustic analysis head 8 is mounted on the substrate 1 through a triangular support leg. The acoustic analysis head 8 analyzes acoustic characteristics. At the same time, through the adjustable position design of the mass block 3, in addition to the tripod, an adjustable center of gravity base is designed to enhance the stability of the device in different scenarios.
[0030] When adjusting the position of mass block 3, the translation component 4 works, thereby moving mass block 3 closer to or further away from the main shaft 5, increasing or decreasing the moving radius of mass block 3. At the same time, the operator can manually rotate the main shaft 5 to move mass block 3 in a circular motion. When mass block 3 moves to the designated position, the pressing component 9 works to position the main shaft 5, thereby limiting the position of mass block 3.
[0031] Example 2
[0032] like Figures 1-4 As shown, the acoustic characteristic analyzer proposed in this utility model, compared with Embodiment 1, further includes: a pressing component 9 consisting of a paddle 901, a screw housing 902, a friction block 903, a shaft head block 904, and a screw seat 905. The screw seat 905 is located on the lower surface of the base plate 1, the screw housing 902 is threaded onto the screw seat 905, the friction block 903 is rotatably located at the central axis of the screw housing 902, the shaft head block 904 is located at the bottom end of the main shaft 5, the friction block 903 presses tightly against the shaft head block 904, and the paddle 901 is located on the outer wall of the screw housing 902. When the pressing component 9 is working, the operator manually rotates the screw housing 902 through the paddle 901. Through the threaded engagement between the screw housing 902 and the screw seat 905, the friction block 903 is driven to abut against the surface of the shaft head block 904, and under the action of strong friction, the main shaft 5 is prevented from rotating.
[0033] The translation component 4 consists of a connecting seat 401, a screw 402, a cap 403, and a screw block 404. The connecting seat 401 is mounted on the main shaft 5. The screw 402 is rotatably mounted on the connecting seat 401. The cap 403 is mounted on the other end of the screw 402. The screw block 404 is threaded onto the screw 402.

The screw block 404 has a screw hole that matches the screw 402. The screw 402 is threaded onto the screw hole. When the translation component 4 is working, the cap 403 is manually rotated to drive the screw 402 to rotate. Through the threaded engagement between the screw block 404 and the screw 402, and at this time the screw block 404 is constrained by the mass block 3 and does not deflect, the rotation of the screw 402 is converted into the translation of the mass block 3 under the principle of the lead screw.
[0034] The lower surface of the substrate 1 is provided with support bases 2. There are four support bases 2 in total, and the positions of the four support bases 2 are distributed in a rectangular array on the lower surface of the substrate 1.
