Resonate with the sound of the surrounding paper or diaphragm and produce electromagnetic resonance with the sound of the surrounding paper or diaphragm. According to the energy exchange mechanism and structure, the electric loudspeaker has the advantages of good electroacoustic performance, firm structure and low cost.

It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity and directional propagation as rays.The working frequency is the resonant frequency of the piezoelectric wafer. When the frequency of the AC voltage applied to both ends is equal to the resonant frequency of the chip, the output energy is the largest and the sensitivity is the highest.
