The core of high-fidelity Bluetooth sound is that it can provide high-fidelity sound effects close to the original sound. This means that the sound equipment can maximize the details of the sound, reduce distortion, and ensure that every note in the music can be clearly and accurately conveyed to the listener.
[0003] As we all know, sound is generated by vibration, such as in the sound equipment "sound" commonly used by people, the main sound generating part is the loudspeaker, the electrical signal will be transmitted to the diaphragm after passing through the driver, and the diaphragm will start to vibrate, and the vibrating diaphragm will generate sound waves in the air, which is the sound we hear.
[0004] That is, when the loudspeaker is working, it will produce vibrations of a certain frequency inside, and as the volume is adjusted, the frequency of the vibration will also rise, and high-frequency vibration will cause the container installed (i.e. the sound) to resonate, and will also cause the internal parts to demagnetize, and even worse, will cause damage, which is not conducive to the stable operation of the sound, so we make improvements and propose a high-fidelity Bluetooth sound anti-resonance structure.
