The traditional speaker uses a voice coil to push a fixed size paper tub to produce sound, and its own structure and characteristics determine that the speaker cannot achieve flat and miniaturization. Secondly, the fixed diameter of the vibration basin makes the speaker's passband very narrow, with poor amplitude frequency characteristics. The entire frequency response characteristic has a single peak characteristic at its mechanical resonance frequency point, resulting in the need for high fidelity speakers to be implemented in a frequency division combination of high, medium, and bass speakers.

The voice coil is a thruster and a part of the vocal body. Its mechanical structure and performance are in conflict, especially in high-fidelity systems. To achieve a large dynamic range, it requires high power. This requires high mechanical strength for the voice coil, and the coil has to be made stronger. However, as the mechanical inertia of the voice coil increases, the high-frequency characteristics will greatly decrease. In order to meet the needs of both mechanical strength and high-frequency characteristics, Voice coils typically operate in extreme environments and are extremely prone to burnout. Therefore, high fidelity speakers designed and manufactured with traditional loudspeakers have large volume, high cost, and poor reliability.

In order to meet the requirements of modern acoustics for the wide frequency response, wide directivity, and miniaturization of speakers, flat panel speakers have begun to "surface", and exhibit extremely attractive application prospects with their outstanding advantages. The typical ones include NXT flat panel speakers and equimagnetic tape speakers, but both have shortcomings such as insufficient low-frequency response and poor sound quality. This paper presents a flat panel speaker system. Through structural analysis, it can be seen that using it as the speaker of a high fidelity speaker can significantly improve the low-frequency response of the flat panel speaker, making the frequency response characteristics of the flat panel speaker more flat.
