Description

Technical Field

[0001] The invention relates to the technical field of human-repelling technology, in particular to a human-repelling signal generator component. Background Art

[0002] When special circumstances arise and the police are unable to disperse the crowd, they need to use a signal generator to send out a dispersal signal to evacuate the crowd.

[0003] However, when using existing signal generators, they usually use a sound amplifier to repeatedly play the evacuation information recorded in advance. Since it has no direct impact on humans, it is difficult for the masses to evacuate directly. This evacuation method is very inefficient, the masses are difficult to disperse, and the speakers are prone to dust accumulation, affecting normal use. Summary of the invention

[0004] The object of the present invention is to provide a human repelling signal generator assembly to solve the problem of low repelling efficiency mentioned in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A speaker assembly, wherein a square frame is inserted into one side of the speaker assembly;

[0007] The isolation component includes a square frame, a filter is fixedly installed on the inner side of the square frame, a handle is fixedly arranged on the top of the square frame, a limit plate is arranged on the top of the square frame, a fixed rod No. 1 penetrates the inside of the end of the limit plate away from the square frame, and a common spring is arranged on the outer periphery below the fixed rod No. 1.

[0008] Preferably, the speaker assembly comprises a speaker body, a battery and a circuit board are arranged inside the speaker body, and a piezoelectric speaker is fixedly mounted on one side of the speaker body close to the square frame.

[0009] Preferably, the square frame is slidably connected to the speaker body, and a groove is formed in the square frame corresponding to the limiting plate.

[0010] Preferably, the limiting plate is movably connected to the No. 1 fixing rod, and the No. 1 fixing rod is fixedly connected to the speaker body.

[0011] Preferably, two ends of the common spring are fixedly connected to the limiting plate and the speaker body respectively.

[0012] A human repelling signal generator component:

[0013] S1. The initial base frequency is 3000Hz, square wave, duty cycle is 1:1~2:1, and on this basis, the frequency is fine-tuned to a ratio of 10%~15%, a period of 15Hz square wave, and amplitude cutting is performed at the same time. The modulation period is synchronized with the frequency modulation, the amplitude is 80%~100%, and the square wave duty cycle is 97%~99%. The above synthesized waveform is amplitude modulated, the frequency is 0.8~1.2Hz, sine wave, and the modulation amplitude is 30%~50%. Insert the circuit board with this frequency into the main body of the speaker;

[0014] S2. When the filter is damaged or needs to be cleaned, lift the limit plate upwards and turn it to the side away from the square frame. Hold the handle and remove the square frame together with the filter from the speaker body for replacement.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the setting of the present invention replaces the originally recorded evacuation information with an adjusted sound wave frequency band. This sound will cause people to feel physiological discomfort, and may cause reactions such as scalp tingling and heartbeat acceleration. This is because the frequency and timbre are related to human perception of danger signals, triggering the brain's aversion mechanism, making people feel uncomfortable and leave quickly or take actions such as covering their ears, thereby making them lose their ability to attack and the possibility of destructive activities. Compared with repeated evacuation information, the effect is more direct, can have a direct impact on humans, and has a higher expulsion efficiency.

[0016] The present invention arranges a filter screen on the periphery of the piezoelectric speaker through the setting of an isolation component. The filter screen serves to isolate dust. When the filter screen is damaged or needs to be cleaned, the limit plate can be lifted upward and turned to the side away from the square frame. The handle is held and the square frame together with the filter screen can be removed from the speaker body for replacement. The operation is simple and quick, which improves the efficiency of replacement and cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
