The utility model provides a control system of strong sound electron bee calling organ of making an uproar falls, this control system of strong sound electron bee calling organ of making an uproar falls includes noise detector 4 and handles end 3, handle end 3 and noise detector 4 and install the upper and lower surface at bee calling organ vibration sound production body 1 respectively, it includes microprocessor 31, memory 33 and drive circuit 32 to handle end 3, noise detector 4's output passes through the API interface and is connected with microprocessor 31, microprocessor 31's output is connected with drive circuit 32, establish data transmission between microprocessor 31 and the memory 33 and be connected.
Here, the driving circuit 32 drives the buzzer vibration sounding body 1, and the noise and the sound wave output by the buzzer vibration sounding body 1 interfere with each other, and the principle is as follows:
when two or more sound waves meet, they add or subtract from each other, affecting each other in superposition, a phenomenon known as wave interference. If their peaks and valleys are perfectly in phase, they reinforce each other, and therefore the amplitude of the resulting waveform is higher than the amplitude of any single waveform. If the peaks and troughs of the two waveforms are completely out of phase, they cancel each other out, resulting in no waveform at all.
However, in most cases, the various sound waves will be out of phase to varying degrees, resulting in a combined waveform that is more complex than a single waveform. For example, complex waveforms representing music, speech, noise and other sounds combine waveforms of various sounds. Because of its unique physical structure, a single instrument can produce extremely complex sound waves. This is why violins and trumpets sound different even though they play the same note.
A control method of a noise reduction strong sound electronic buzzer comprises the following specific steps:
s1: detecting an external noise condition: the noise detector 4 detects the noise decibel of the external environment, and the result detected by the noise detector 4 is output to the microprocessor 31;
