For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] See also Figure 1-4 A multi-band adaptive muffler comprises a muffler body 1 and an adjusting component, wherein the adjusting component is arranged on the inner side of the muffler body 1.

[0031] An electric control module 6 is disposed on the outer surface of the muffler body 1 , a connecting piece 2 is disposed on the left side of the muffler body 1 , and a sound outlet pipe 4 is disposed on the right side of the muffler body 1 .

[0032] In this embodiment, two upper and lower rebound shafts 12 are fixedly installed on the inner side of the connecting member 2, and the opposite sides of the two rebound shafts 12 are both driven and installed with limit bolts 10.

[0033] It should be noted that the transmission installation design of the limit bolt 10 and the rebound shaft 12 enables the muffler to more accurately adjust the resonance characteristics of the internal structure when dealing with noise in different frequency bands, thereby achieving efficient silencer of noise in a specific frequency band. This design improves the frequency selectivity and silencer efficiency of the muffler.

[0034] In this embodiment, reinforcement members 5 are fixedly installed on the upper and lower sides of the outer wall of the connecting member 2, and positioning blocks 14 that are clamped on the inner side of the connecting member 2 are provided on the opposite sides of the two reinforcement members 5. The setting of the positioning blocks 14 ensures that the reinforcement members 5 can be accurately clamped on the inner side of the connecting member 2 to achieve a tight fit between the two. Fixed bolts 13 are fixedly installed on the outer surfaces of the two reinforcement members 5. The introduction of the fixed bolts 13 makes the installation and disassembly of the reinforcement members 5 more convenient.

[0035] It should be noted that the fixed installation of the reinforcement member 5 significantly enhances the structural strength of the connecting member 2, further protecting the muffler body so that it can better resist deformation when subjected to sound wave impact or external pressure, thereby maintaining the stability and integrity of the structure.

[0036] In this embodiment, a threaded column 3 is threadedly connected to the inner side of the right end of the silencer body 1, a sound-absorbing layer 9 is fixedly installed on the inner wall side of the silencer body 1, and the sound-absorbing layer 9 is attached to the outer side of the threaded column 3. A sound outlet pipe 4 is fixedly installed on the right end of the threaded column 3, and a plurality of slots are opened on the outer surface of the sound outlet pipe 4.

[0037] It should be noted that the introduction of the sound-absorbing layer 9 significantly improves the sound-absorbing effect of the muffler. The sound-absorbing layer 9 can absorb and transform sound wave energy, reduce the reflection and propagation of sound waves inside the muffler, thereby achieving effective noise suppression. At the same time, the sound-absorbing layer 9 is attached to the outer side of the threaded column 3, ensuring that the sound waves can fully contact the sound-absorbing material when passing through the muffler, thereby improving the sound-absorbing efficiency.

[0038] The plurality of slots formed on the outer surface of the sound outlet tube 4 help to adjust the propagation direction and speed of the sound waves. These slots can change the propagation path of the sound waves in the sound outlet tube and reduce the sound wave energy in a specific frequency band, thereby achieving adaptive silencing of multi-band noise.

[0039] The adjusting component comprises a reflection plate 8 . A resonance block 7 is arranged on the inner side of the muffler body 1 . The reflection plate 8 is movably mounted on the inner wall side of the muffler body 1 . The resonance block 7 is slidably mounted on the outer surface of the resonance block 7 .

[0040] In this embodiment, a row of resonance blocks 7 are fixedly mounted on the inner side of the muffler body 1 . The resonance blocks 7 are triangular in shape, and reflection plates 8 are slidably mounted on the inner sides of adjacent resonance blocks 7 .

[0041] It should be noted that by installing the reflecting plate 8, the propagation path of the sound waves can be effectively changed, causing the sound waves to reflect and interfere multiple times inside the silencer, thereby consuming more sound wave energy and improving the sound elimination effect. The sliding installation design of the reflecting plate 8 allows its position to be flexibly adjusted to adapt to the characteristics of sound waves in different frequency bands, further improving the targetedness and efficiency of sound elimination.

[0042] In this embodiment, a circle of reflective plates 8 is transmission-connected to the bottom with a telescopic shaft 11, which is fixedly mounted on the inner side of the muffler body 1, and is circuit-connected to the electronic control module 6. Sliding blocks 15 which can fit with the resonance block 7 are provided on the left and right sides of the reflective plates 8, and a circle of reflective plates 8 can form a circle by fitting with the top of the resonance block 7.

[0043] It should be noted that since sound waves in different frequency bands have different propagation characteristics and reflection laws, the position and angle of the reflector 8 can be adjusted through the transmission of the telescopic shaft 11, so that effective control of sound waves in different frequency bands can be achieved. This design enables the silencer to have a wider range of multi-band adaptability and can cope with complex and changeable noise environments.

[0044] The beneficial effects of the above embodiments are:

[0045] By adding a connecting piece 2 and a reinforcing piece 5, as well as an inner reflective plate 8 and a sound-absorbing layer 9, the muffler can cover a wider frequency range and effectively suppress noise in multiple frequency bands. At the same time, with the help of the transmission of the telescopic shaft 11 and the sliding of the resonance block 7, the space inside the muffler body 1 can be adjusted and changed to absorb different noise frequency bands.

[0046] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
