In order to improve the performance of the speaker, the following methods can be adopted:
Low-frequency radiation improvement: Use composite side speakers or baffles, speakers (such as open boxes, closed boxes, and reflex boxes) to reduce the resonant frequency and improve low-frequency response .
High-frequency radiation improvement: Use a double-cone structure or a combination of multiple speakers to use the characteristics of different cones to widen the operating frequency band and reduce intermodulation distortion .
Voice coil inductance compensation: Add a short-circuit ring or coil to the magnetic circuit system to reduce the influence of the voice coil inductance and improve high-frequency radiation.
