[0002] The voice coil is an important component of the loudspeaker. Its function is to generate a magnetic field in the coil through the current. The charged wire is acted upon by the Lorentz force in the magnetic field, causing it to move, which in turn drives the related components to vibrate and produce sound. The performance of the voice coil directly affects the sound intensity characteristics, impedance curve, and sound quality of the loudspeaker.

[0003] In order to enhance and optimize specific aspects of the audio signal and improve the sound quality and listening experience, an effect enhancer is required.
