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.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1:

[0031] Please see Figures 1-5 As shown, this utility model provides an analog and digital dual-domain audio monitoring instrument, including a dual-domain audio monitoring instrument body 1. A fixed frame 8 is fixedly connected to the back of the dual-domain audio monitoring instrument body 1. Pin holes 14 are opened at both ends of the bottom of the fixed frame 8. A connecting shaft 20 is movably connected to the upper end of the inner cavity of the fixed frame 8 through a bearing. A torsion spring 19 is fixedly connected between the middle end of the connecting shaft 20 and the top of the inner cavity of the fixed frame 8. An adjusting plate 13 is fixedly connected between the two ends of the connecting shaft 20. The surface of the adjusting plate 13 contacts the inner cavity of the fixed frame 8. An elastic anti-detachment strap 12 is fixedly connected between the two ends of the back of the adjusting plate 13. A receiving cavity 21 is opened at the lower end of the adjusting plate 13. A pin 15 is slidably connected between the bottom of the receiving cavity 21 and the surface of the pin hole 14. A horizontal plate 22 is fixedly connected between the tops of the two pins 15. A push rod 16 is fixedly connected to the back of the horizontal plate 22.

[0032] In this technical solution, by adjusting the elastic anti-slip strap 12 on the back of the plate 13, the hand can be inserted into the elastic anti-slip strap 12 during the process of holding and using the dual-domain audio monitor body 1. Under the action of the elastic anti-slip strap 12, it can be tightly pressed against the hand, thus creating a certain restraint between the dual-domain audio monitor body 1 and the hand, thereby reducing the probability of the dual-domain audio monitor body 1 slipping off the hand during use, improving the overall anti-slip effect during use. Furthermore, through the pin hole 15 and the pin rod 14... The configuration of the adjustment plate 13 and the lower end of the fixed frame 8 can limit the movement of the adjustment plate 13 and the connecting shaft 20 along the bearing on the fixed frame 8 during the handling and use process. At the same time, the push rod 16, the horizontal plate 22, the pin 15, the pin hole 14, the torsion spring 19, the connecting shaft 20, the adjustment plate 13 and the fixed frame 8 can support the dual-domain audio monitor body 1 in an inclined manner during the placement and use of the dual-domain audio monitor body 1 by the personnel, so as to facilitate the operation and use of the dual-domain audio monitor body 1.

[0033] Example 2:

[0034] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a dual-domain audio monitor body 1 has silicone pads 2 fixedly connected to both sides, silicone protrusions 3 fixedly connected to the surface of the silicone pads 2, guide grooves 17 are provided at both ends of the top of the inner cavity of the fixed frame 8, guide blocks 18 are fixedly connected to both ends of the top of the adjustment plate 13, the surface of the guide blocks 18 is slidably connected to the surface of the guide grooves 17, a support spring 23 is fixedly connected to the top of the horizontal plate 22, the top of the support spring 23 is fixedly connected to the top of the receiving cavity 21, a control panel is fixedly installed on the upper end of the front surface of the dual-domain audio monitor body 1, a USB interface 7 is fixedly installed on the upper right side of the dual-domain audio monitor body 1, a headphone jack 4, a DC input port 5 and a power switch 6 are fixedly installed on the top of the dual-domain audio monitor body 1 from left to right, and an OUTPUT port 11, an INPUT port 10 and an SDI input port 9 are fixedly installed on the bottom of the dual-domain audio monitor body 1 from left to right.

[0035] In this technical solution, the silicone pad 2 and silicone protrusion 3 can form good collision protection around the dual-domain audio monitor body 1, effectively reducing the probability of damage to the dual-domain audio monitor body 1 due to drop or collision, and improving the safety protection effect of the dual-domain audio monitor body 1. The guide block 18 and guide groove 17 can effectively limit and guide the adjustment plate 13 during rotation adjustment. The support spring 23 can achieve the purpose of elastic support for the top of the horizontal plate 22, and under the action of the support spring 23, the pin 15 can be inserted into the surface of the pin hole 14.

[0036] The working principle of this utility model is as follows: By adjusting the elastic anti-slip strap 12 on the back of the adjusting plate 13, the user's hand can be inserted into the elastic anti-slip strap 12 during the holding and use of the dual-domain audio monitor body 1. Under the action of the elastic anti-slip strap 12, the hand is tightly pressed against the user's hand, thus creating a certain restraint between the dual-domain audio monitor body 1 and the user's hand. This reduces the probability of the dual-domain audio monitor body 1 slipping off the user's hand during use, improving the overall anti-slip effect. Simultaneously, the pin hole 15 and pin rod 14 limit the movement between the adjusting plate 13 and the lower end of the fixed frame 8, preventing slippage during holding and use. In the process, the adjusting plate 13 and the connecting shaft 20 rotate along the bearing on the fixed frame 8. When the user needs to place the dual-domain audio monitor body 1 for use, the push rod 16 is pushed upward to move the horizontal plate 22 and the pin 15, causing the pin 15 to disengage from the surface of the pin hole 14. Under the action of the pre-compressed reaction force of the torsion spring 19, the connecting shaft 20 and the adjusting plate 13 can rotate and tilt along the bearing on the fixed frame 8. This allows the adjusting plate 13 to support the back of the dual-domain audio monitor body 1 during placement, while also allowing the dual-domain audio monitor body 1 to be placed on the table at an angle, making it easier for the user to operate and use.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
