[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 An audio signal analyzer in this embodiment includes a supporting base 1, an analyzer body 2 is arranged on the top of the supporting base 1, and an adjustment mechanism 5 is arranged between the supporting base 1 and the analyzer body 2.

[0025] The analyzer body 2 is composed of a power supply, an interface 3, a signal processing unit, a measurement and analysis unit and a display screen 4. When using the device, the audio device or signal source to be analyzed is connected to the interface 3 of the audio signal analyzer, and the power supply is connected, and the signal processing unit starts to work. After the signal processing unit is started, the audio signal analyzer will automatically process and analyze the input signal, and the analysis result will be displayed through the display screen 4, and the user can read the test result on the display screen 4.

[0026] The adjusting mechanism 5 includes a accommodating chamber 501, an adjusting rod 502, a moving block 503, a limiting block 504, a sliding groove 505 and a connecting rod 506. The supporting base 1 has a accommodating chamber 501 inside, the adjusting rod 502 is rotatably installed inside the accommodating chamber 501, the moving block 503 is threadedly connected to the outer surface of the adjusting rod 502, the limiting block 504 is fixedly installed at the bottom of the moving block 503, the inner bottom wall of the accommodating chamber 501 is provided with a sliding groove 505, and the top of the moving block 503 is rotatably installed with a connecting rod 506.

[0027] A bearing seat is provided on the left inner wall of the accommodating cavity 501, and one end of the adjusting rod 502 is rotatably connected to the inner wall of the accommodating cavity 501 through the bearing seat, and the other end of the adjusting rod 502 passes through the right side wall of the supporting base 1 and is fixedly installed with an anti-slip knob. The adjusting rod 502 is driven to rotate by rotating the anti-slip knob, thereby adjusting the angle of the display screen 4.

[0028] A non-slip pad is provided at the bottom of the support base 1 to improve the stability of the device when placed. A mounting bracket is fixedly installed on the top left end of the support base 1. The left end of the analyzer body 2 is rotatably connected to the mounting bracket, and the right end is rotatably connected to the moving block 503. Under the rotation of the adjustment rod 502 and the movement of the moving block 503, the analyzer body 2 is driven to rotate on the mounting bracket, so that the display angle of the display screen 4 is changed. When reading the data on the display screen 4, the display screen 4 can be adjusted to the best viewing angle, thereby improving convenience during use and reducing fatigue.

[0029] The interface 3 and the display screen 4 are both arranged on the right side of the analyzer body 2 . Arc-shaped airbags 301 are movably installed on both sides of the interface 3 . Springs 302 are fixedly installed between the opposite sides of the two arc-shaped airbags 301 and the inner wall of the interface 3 .

[0030] The spring 302 can be deformed when subjected to external force and return to its original shape after the external force is removed. Installing the spring 302 at the interface 3 can provide a certain pressure to make the connection tighter, thereby reducing wear and looseness caused by vibration or other external forces. The arc-shaped airbag 301 can absorb impact force. It can play a buffering role when the interface 3 is subjected to a large impact, reducing direct damage to the interface 3. In addition, the arc-shaped airbag 301 can also adapt to the size changes of the wiring port to a certain extent and maintain the stability of the connection.

[0031] When implementing, follow these steps:

[0032] 1) When in use, first insert the wiring into the interface 3, and under the contraction and expansion of the spring 302, the two arc-shaped airbags 301 fix the wiring, so that the wiring is stably connected to the analyzer body 2;

[0033] 2) Then the power is turned on, and after being processed by the signal processing unit and the measurement and analysis unit, the final result is displayed on the display screen 4;

[0034] 3) When adjusting the viewing angle of the display screen 4, firstly, the adjusting rod 502 is rotated by the anti-slip knob, and the adjusting rod 502 drives the moving block 503 to move rightward on the surface of the adjusting rod 502. When the moving block 503 moves, it drives the limit block 504 to slide inside the slide groove 505, and the movement of the moving block 503 drives the connecting rod 506 to rotate;

[0035] 4) Finally, the connecting rod 506 rotates to drive the analyzer body 2 to rotate on the mounting frame, thereby adjusting the display screen 4 to a suitable reading angle.

[0036] In summary, by setting the adjustment mechanism 5, the analyzer body 2 can be rotated to adjust the angle of the display screen 4, so that the operator can find a suitable angle to observe the data on the display screen 4 in different working environments without turning the head and body, thereby improving the comfort during use.

[0037] Furthermore, by arranging an arc-shaped airbag 301 and a spring 302 in the interface 3, the arc-shaped airbag 301 and the spring 302 can absorb the impact force generated during plugging and unplugging, reduce the physical wear of the interface 3 and the wire, extend the service life, and make the connection tighter, improve the stability of the connection, and ensure the continuity and reliability of signal transmission.
