[0003] The existing voice processing devices for simulating ground-air communication are large in size, which will occupy too much desktop space of the operation console during use. Moreover, they only support the use of aviation plug hand-held headphones, and the market price of this accessory is high. As a consumable that is easily damaged, it greatly increases the use cost of the control simulator. At the same time, the large size makes maintenance and repair very inconvenient. In addition, most of the plug-in interfaces of the existing voice processing devices are exposed, and dust will enter these plug-in interfaces when not in use, resulting in blockage of the plug-in interfaces, thus affecting the normal use of the device. Summary of the Utility Model

[0004] In view of the problems in the related art, the utility model provides a voice processor to overcome the above technical problems existing in the related art.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model provides a voice processor, which includes a protective shell, a voice processing module, an opening and closing assembly, and side baffles. The voice processing module is placed inside the protective shell. The opening and closing assembly is installed on the protective shell. The opening and closing assembly includes a main opening and closing plate and a sub-opening and closing plate. The main opening and closing plate and the sub-opening and closing plate are rotatably arranged on the upper side of the protective shell. The main opening and closing plate can drive the sub-opening and closing plate to open and close on the protective shell. Side baffles are arranged on both sides of the protective shell, and dust-proof boxes are installed on the side baffles. Plug-in interfaces are arranged inside the dust-proof boxes, and the plug-in interfaces are connected to the voice processing module.

[0007] Furthermore, an installation groove is formed on one side of the protective shell.

[0008] Furthermore, rotating shafts are fixedly connected to both sides of the main opening and closing plate. The rotating shafts are rotatably connected to the protective shell. One of the rotating shafts penetrates through the protective shell and the side baffle on the same side. An active gear and an opening and closing knob are coaxially and fixedly connected to this rotating shaft in sequence. The active gear is located inside the installation groove, and the opening and closing knob is located outside the side baffle. Anti-slip lines are provided on the opening and closing knob, and a clamping block is fixedly connected to the main opening and closing plate.

[0009] Further, both sides of the auxiliary opening and closing plate are also fixedly connected with the rotating shaft, the rotating shaft is rotatably connected to the protective shell, a driven gear is coaxially and fixedly connected to the rotating shaft on one side, the driven gear is located in the installation groove, and the driven gear meshes with the driving gear. A fitting groove is formed in the auxiliary opening and closing plate, and the fitting groove corresponds to the block.

[0010] Further, sliding grooves are formed on the outer sides of both sides of the dust-proof box, grooves are formed on the side baffle, the grooves are located above the dust-proof box, a dust-proof cover is arranged on the dust-proof box, and rotating shafts are fixedly connected to both sides of the dust-proof cover. The rotating shafts are slidably installed in the sliding grooves. When the rotating shafts slide in the sliding grooves, the dust-proof cover can be driven to rotate, and the grooves correspond to the dust-proof cover.

[0011] Further, a number of fixing screw holes are correspondingly formed in the side baffle and the protective shell, fixing bolts are assembled in the fixing screw holes, and the side baffle is fixedly connected to the protective shell through the fixing bolts.

[0012] Further, the voice processing module is located between the two side baffles and is fixedly installed at the bottom inside the protective shell.

[0013] Further, the wire plug interface is composed of a variety of model interfaces and is arranged in the dust-proof box in sequence.

[0014] The utility model has the following beneficial effects: By using a voice processor, during use, manually pull the dust-proof cover closed on the dust-proof box outwards, the dust-proof cover is separated from the dust-proof box, the rotating shaft on the dust-proof cover slides to the front end in the sliding groove, then lift the dust-proof cover upwards, so that the rotating shaft continues to slide along the sliding groove, and turn the dust-proof cover upwards by 90 degrees. At this time, the dust-proof cover is attached to the upper side of the dust-proof box, and then push the dust-proof cover into the groove to open the dust-proof box. After opening the dust-proof covers on both sides, connect an external device to the wiring interface. Among them, the wiring interface can connect to an aviation plug hand-held PTT headset, 3.For devices such as 5-interface general-purpose headsets for telephone calls and industrial control foot pedals, etc., the voice processor can then be used. During use, after the external device inputs the signal into the voice processing module for processing, the voice processing module then outputs it to the user. The design of the voice processing module adopts a simplified process. On the premise of ensuring the realization of analog communication functions, the USB transmission technology is used, which greatly reduces the hardware complexity of voice transmission and control and can be compatible with different types of hardware. After using the voice processor and unplugging the external device, drag out the dust cover in the groove, and then pull down the dust cover and rotate it 90 degrees, and then push the dust cover towards the dust box to close the dust box with the dust cover. During maintenance and repair, rotate the opening and closing knob forward 90 degrees. The opening and closing knob drives the rotating shaft on it to rotate, flipping the main opening and closing plate upwards 90 degrees, and rotating the driving gear on it. When the driving gear rotates, it drives the driven gear meshing with it to rotate in the opposite direction. The driven gear drives the auxiliary opening and closing plate to flip upwards 90 degrees through the rotating shaft on it. The main opening and closing plate and the auxiliary opening and closing plate approach each other when flipping. When both flip 90 degrees, the latch on the main opening and closing plate inserts into the fitting groove of the auxiliary opening and closing plate to fix the main opening and closing plate and the auxiliary opening and closing plate to prevent them from falling. At this time, the upper side of the protective shell is opened. Stop rotating the locking knob, and then the components inside the protective shell can be maintained and repaired. After completing the maintenance and repair, rotate the opening and closing knob backward 90 degrees. The rotating shaft on it drives the main opening and closing plate to flip downwards 90 degrees and drives the driving gear on it to rotate. The driving gear drives the driven gear meshing with it to rotate in the opposite direction. The driven gear drives the auxiliary opening and closing plate to flip downwards 90 degrees through the rotating shaft on it. The latch on the main opening and closing plate is pulled out of the fitting groove, and the main opening and closing plate and the auxiliary opening and closing plate are separated, and the protective shell is closed again. Through the simplified design of the voice processing module, the volume of the voice processor is reduced, making the voice processor miniaturized, and it can be compatible with a variety of hardware for use, reducing the use cost of the control simulator, improving the applicability of the voice processor. At the same time, the simplified design makes the voice processor easier to maintain and repair. Through the setting of the opening and closing component, when maintenance and repair are required, only the main opening and closing plate and the auxiliary opening and closing plate need to be opened to maintain and repair the components inside the protective shell, making the maintenance and repair of the voice processor very convenient. Through the setting of the dust box, when the voice processor is not in use, the dust cover closes the dust box to prevent dust from entering the wiring interface and causing the wiring interface to be blocked, thus affecting the subsequent use of the voice processor and ensuring the normal subsequent use of the voice processor.

[0033] Among them, when manually opening the dust-proof box 71, the dust-proof cover 73 closed on the dust-proof box 71 is pulled outwards. The dust-proof cover 73 is separated from the dust-proof box 71. The rotating shaft 731 on the dust-proof cover 73 slides to the front end in the sliding groove 711. Subsequently, the dust-proof cover 73 is lifted upwards, so that the rotating shaft 731 continues to slide along the sliding groove 711, and the dust-proof cover 73 is turned upwards by 90 degrees. At this time, the dust-proof cover 73 is attached to the upper side of the dust-proof box 71. Subsequently, the dust-proof cover 73 is pushed into the groove 72, thereby opening the dust-proof box 71. When closing the dust-proof box 71, the dust-proof cover 73 in the groove 72 is pulled out, and the dust-proof cover 73 is turned downwards by 90 degrees, and then the dust-proof cover 73 is pushed towards the dust-proof box 71, so that the dust-proof cover 73 closes the dust-proof box 71.

[0034] In one embodiment, for the above-mentioned voice processor, a number of fixing screw holes 8 are correspondingly provided on the side baffle 7 and the protective shell 1.
