the following describes in detail the case 1 for storing the audio monitoring device in this embodiment, which specifically includes the following steps:

as shown in fig. 1, the upper and lower ends of the case 1 are fixed to an upper site to be monitored (for example: site wall or other position that can be used for realizing the installation of the box body 1), as shown in fig. 2, the fan 2 is respectively installed at two ends in the box body 1, a spring is connected between the fan 2 and the box body 1, when the fan 2 starts to work, an internal motor vibrates and drives the fan 2 to shake vertically relative to the box body 1, the vibration can be buffered and absorbed by the spring arranged between the fan 2 and the box body 1, the vibration generated by the operation of the fan 2 can be reduced to the box body 1 as far as possible (so as not to influence the normal operation of audio monitoring equipment in the box body 1), the two ends in the box body 1 are respectively provided with a silencing cavity 4 (an equipment cavity 6 is arranged between the two silencing cavities 4 and used for placing audio monitoring equipment, the equipment cavity 6 is arranged between the two partition boards 20), and a silencing pipe 5 is installed in the silencing cavity 4, the silencing pipes 5 are communicated with the fans 2 corresponding to the silencing pipes, as shown in fig. 2, when the fans 2 arranged at two sides of the box body 1 work, air flows enter from one side of the box body 1 and are discharged from the other side of the box body 1 after passing through the equipment cavity 6, so that the audio monitoring equipment in the equipment cavity 6 is cooled and radiated, as the density of hot air is smaller than that of cold air, the hot air in the equipment cavity 6 is concentrated above a dotted line frame and two side areas of the dotted line frame, as shown in fig. 3, 3 silencing pipes 5 are arranged in each silencing cavity 4 in a pattern in the drawing, and when the fans 2 are started and generate air flows, the audio monitoring equipment in the equipment cavity 6 is arranged in the dotted line frame in fig. 3, and the air flows are respectively guided to the top area in the equipment cavity 6 through the guidance of the three silencing pipes 5, two side areas, which are used for taking away the heat in the areas along with the airflow and finally discharging the heat out of the box body 1;

as shown in fig. 1, a ventilation window 3 for heat dissipation is provided at the front end of the box body 1, when the temperature in the equipment cavity 6 in the box body 1 is in a normal range, the fan 2 is not required to be started at this time, and the heat dissipation requirement can be met by natural ventilation through the ventilation window 3, and since the fan 2 is not started, the box body 1 will not vibrate and noise will not be generated to interfere with the normal operation of the audio monitoring equipment in the box body 1;

when the ambient temperature is higher, the natural ventilation through the ventilation window 3 can not meet the heat dissipation requirement, and the fan 2 can only be controlled to start to forcedly dissipate heat to the environment in the equipment cavity 6, so that the audio monitoring equipment can work in a proper temperature interval (a temperature sensor can be installed in the equipment cavity 6 and electrically connected with the microcontroller, and the microcontroller can control the start of the fan 2 and the corresponding running power), and the method is as follows:

when the fan 2 is started, air flow is conveyed into the equipment cavity 6 from one side of the box body 1 through three silencing pipes 5 arranged in the silencing cavity 4, the air flow passes through the equipment cavity 6 and takes away hot air along with the air flow, and finally the hot air is discharged out of the box body 1 through the silencing pipes 5 arranged in the left silencing cavity 4, so that the cooling and heat dissipation processes are realized, vibration and noise (transmitted in the form of sound waves) are generated due to the operation of the fan 2, and part of sound waves can be absorbed by the silencing pipes 5 in the transmission process of the sound waves in the silencing pipes 5 so as to weaken the energy of the sound waves, and the noise energy finally transmitted into the equipment cavity 6 is reduced to a lower level as much as possible;

in this embodiment, the silencing pipes 5 installed in the two silencing cavities 4 realize filtering and absorbing of noise generated when the fans 2 arranged on two sides of the box body 1 work, so as to weaken energy of noise sound waves and further reduce noise transmitted into the equipment cavity 6;

the fan 2 and the box body 1 are vertically and slidably arranged, and the spring is arranged between the fan 2 and the box body 1, so that when the fan 2 starts to work, vibration generated by the fan is buffered and absorbed, the degree of transmission of vibration energy generated by the fan 2 to the box body 1 is weakened, and the box body 1 is in a relatively stable state as much as possible;

the fan 2 operating power in this scheme can be according to the size of equipment intracavity 6 temperature and corresponding by microcontroller control, if the temperature in the equipment intracavity 6 continuously rises when, microcontroller control fan 2 increases operating power to realize stronger cooling effect, if the equipment intracavity 6 temperature begins when falling, the corresponding reduction of its operating power of fan 2 of microcontroller control is in order to realize under the prerequisite that satisfies the cooling demand, the effect of saving the electric energy (also reduce the noise amplitude because of fan work produces simultaneously).

In embodiment 2, on the basis of embodiment 1, as shown in fig. 2, rectangular cavities 7 are provided at two ends of a box body 1, a fan 2 is provided in the rectangular cavities 7, one end of the rectangular cavity 7 facing away from the box body 1 is provided with an opening 18 (not shown in the figure) corresponding to the fan 2, so as to realize air flow inlet (outlet), slide bars 8 are respectively provided at the upper and lower ends of the fan 2 and are vertically and slidably mounted in the rectangular cavities 7 through the slide bars 8, springs are sleeved on the slide bars 8 and are connected between the top wall of the rectangular cavity 7 and the body of the fan 2, the rectangular cavity 7 is communicated with the corresponding silencing pipe 5, when the fan 2 is started, generated air flow enters the silencing pipe 5 from the rectangular cavity 7, finally enters the equipment cavity 6, and takes away hot air in the equipment cavity 6, and is then discharged outwards from the silencing pipe 5 and the rectangular cavity 7 at the other side.

In the embodiment 3, on the basis of the embodiment 1, as shown in fig. 2, a silencing pipe 5 comprises a vertical part 9 and horizontal parts 10 communicated with two ends of the vertical part 9, wherein one horizontal part 10 is communicated with an equipment cavity 6, the other horizontal part 10 is communicated with a rectangular cavity 7 corresponding to the vertical part, a bearing cylinder 11 (the inside is of a hollow structure) is coaxially arranged in the two horizontal parts 10, a flexible sound absorbing material 12 is arranged on the outer circumferential surface of the bearing cylinder 11 (arranged around the outer circumferential surface of the bearing cylinder 11), an annular balloon 13 is arranged between the flexible sound absorbing material 12 and the outer wall of the bearing cylinder 11, the annular balloon 13 is connected with a gas generator, and a through hole 14 is arranged on the outer wall of the bearing cylinder 11 so as to realize the communication between the annular balloon 13 and the hollow structure inside the bearing cylinder 11;

in this embodiment, when the fan 2 is not started, the annular balloon 13 is filled with a certain amount of gas and is in a certain expansion state, so that the flexible sound absorbing material 12 arranged outside the annular balloon 13 is expanded to a certain extent (as shown in a partial enlarged view in fig. 4), and the expansion degree of the flexible sound absorbing material 12 arranged outside the annular balloon 13 is low (some parts are in an un-expanded state) because the expansion degree of the annular balloon 13 is low;

when the fan 2 is started, noise generated by the operation of the fan is transmitted into the equipment cavity 6 along the silencing pipe 5, and when noise sound waves are transmitted in the silencing pipe 5, the sound waves strike the flexible sound absorbing material 12 in a stretched state to a certain extent and are absorbed by the flexible sound absorbing material 12, so that the energy value of the noise is weakened, and the noise value transmitted into the equipment cavity 6 is further reduced;

if the temperature in the equipment cavity 6 continuously rises (the running power of the fan 2 increases), the generated noise value is synchronously increased, at the moment, a certain amount of gas is conveyed into the bearing cylinder 11 through the gas generator and enters the annular balloon 13 through the through hole 14 to further expand, and as the annular balloon 13 further expands, the flexible sound absorbing material 12 which is not fully expanded further expands (the expansion degree is increased, and the interception capability of the noise sound wave is enhanced), as shown in the partial enlarged diagrams in fig. 5 and 6, as the expansion degree of the annular balloon 13 increases, more noise sound waves collide with (contact with) the flexible sound absorbing material 12 in the transmission process of the noise sound wave in the silencing pipe 5 and are absorbed by the flexible sound absorbing material to improve the filtering and absorption capacity of the noise;

if the temperature in the equipment chamber 6 decreases (the operating power of the fan 2 decreases, so that the airflow velocity is reduced), the noise value generated by the fan is also synchronously reduced, at this time, the gas originally conveyed into the annular balloon 13 is gradually pumped out by the gas generator, so that the expansion degree of the annular balloon 13 is reduced, and further, the expansion degree of the flexible sound absorbing material 12 is reduced (the corresponding filtering and absorption amount of the noise sound wave is reduced), because the noise value is gradually reduced, the influence on the equipment chamber 6 is reduced, at this time, the expansion degree of the annular balloon 13 is reduced, so as to avoid affecting the smooth circulation of the air flow in the silencer 5, because the larger the expansion degree of the annular balloon 13 is, the larger the flow obstruction degree of the air flow in the silencer 5 is, and at this time, the operating power of the fan 2 is reduced (the airflow velocity is reduced), so as to further affect the heat dissipation effect on the equipment chamber 6.

In the embodiment 4, on the basis of the embodiment 3, as shown in fig. 4, the gas generator comprises gas cylinders 15 arranged at the upper end and the lower end of a rectangular cavity 7, a piston 16 is arranged in each gas cylinder 15, the piston 16 is fixedly connected with a sliding rod 8 corresponding to the piston 16, one end of each gas cylinder 15 close to the rectangular cavity 7 is communicated with the outside, one end far away from the rectangular cavity 7 is communicated with a bearing cylinder 11 corresponding to the rectangular cavity 7, one end of each gas cylinder 15 far away from the rectangular cavity 7 is provided with a pipe B, one bearing cylinder 11 in each silencing pipe 5 is provided with a pipe a (the pipe a extends outwards from the silencing pipe 5 and is communicated with the a pipe a), the other bearing cylinder 11 is provided with a pipe B (the pipe B extends outwards from the silencing pipe 5 and is communicated with the B pipe), and in the scheme, three silencing pipes 5 are arranged in the silencing cavity 4, and therefore, the three A pipes in the three silencing pipes 5 are communicated with the a pipe B;

when the fan 2 is started to work, vibration is generated and a shaking amplitude is generated vertically, namely, the corresponding piston 16 is driven to move in the corresponding air cylinder 15, as shown in fig. 5, and the shaking displacement generated by the upward direction of the fan 2 is taken as an example for description and illustration:

stage one: as shown in fig. 5, when the fan 2 moves upwards, the piston 16 (corresponding to the B pipe) is driven to move upwards synchronously to convey the gas into the bearing cylinder 11 corresponding to the B pipe and the B pipe, so that the corresponding annular balloon 13 is inflated (the expansion degree of the flexible sound absorbing material 12 is increased, the filtering and absorption amount of the noise sound wave is increased), meanwhile, the other piston 16 (corresponding to the a pipe) moves synchronously in the air cylinder 15 corresponding to the air cylinder, and the gas in the annular balloon 13 corresponding to the piston is pumped out (the expansion degree of the annular balloon 13 is reduced) through the a pipe and the a pipe, and at the moment, the noise sound wave flowing through the silencing pipe 5 is mainly filtered by the flexible sound absorbing material 12 corresponding to the B pipe;

stage two: as shown in fig. 6, when the fan 2 moves downward, the piston 16 (corresponding to the a pipe) is driven to move upward synchronously to convey the gas into the corresponding carrying cylinder 11 through the a pipe and the a pipe, so that the corresponding annular balloon 13 is inflated (the expansion degree of the flexible sound absorbing material 12 is increased, the filtering and absorption amount of the noise sound wave are increased), meanwhile, the other piston 16 (corresponding to the B pipe) moves synchronously in the corresponding air cylinder 15, and the gas in the corresponding annular balloon 13 is pumped out through the B pipe and the B pipe (the expansion degree of the annular balloon 13 is reduced), and at the moment, the noise sound wave flowing through the silencing pipe 5 is mainly filtered by the flexible sound absorbing material 12 corresponding to the a pipe;

because the fan 2 is operated with higher vibration frequency, the above process (two stages) can be completed in a shorter time interval, that is, the two annular balloons 13 installed in the silencing tube 5 are alternately inflated (with extremely short time interval), so that the noise sound wave can be filtered and absorbed as much as possible under the cooperation of the two flexible absorbing materials in the process of transmitting the noise sound wave in the silencing tube 5, if the noise sound wave is filtered and absorbed in the position of the tube A, the noise sound wave is further filtered and absorbed when the noise sound wave is transmitted to the position of the tube B, and thus better noise reduction effect is realized.

In embodiment 5, on the basis of embodiment 3, a tapered portion 17 is provided on the side of the carrier 11 facing the airflow direction to guide the airflow, so that the arrangement of the carrier 11 is reduced as much as possible to flow the airflow in the muffler pipe 5.

because this part of noise that gets into in the equipment chamber 6 influences, the interference is great to the monitoring equipment in the equipment chamber 6, therefore, also set up flexible sound absorbing material 12 at the amortization pipe 5 inner wall, as shown in fig. 4, when noise sound wave gets into in the horizontal part 10 by rectangular chamber 7, when it is transmitted to horizontal part 10 and vertical portion 9 junction position, noise sound wave can strike the flexible sound absorbing material 12 of locating above-mentioned junction position department (noise sound wave is filtered, absorbed), then noise sound wave continues to remove along vertical portion 9, so that when removing to vertical portion 9 and another horizontal portion 10 junction position, noise sound wave strikes above-mentioned junction position again (noise, sound wave further filter, absorbed) in addition under the processing of setting up in annular sacculus 13 outside flexible sound absorbing material 12 (annular), thereby realize reducing the noise sound wave energy that will transmit to in the equipment chamber 6 as far as possible and minimizing.

Embodiment 8, on the basis of embodiments 1-7, the flexible sound absorbing material 12 in the scheme is vinyl sponge, and is arranged into a shape matched with the silencing pipe 5 and the bearing cylinder 11 according to actual installation requirements and is installed (by gluing or other fixing modes);
