A structure of a rectangular transducer is provided. The structure includes a magnet assembly, a voice coil assembly and a positioning assembly. The magnet assembly has a pair of magnetic units with a gap therebetween for generating two magnetic fields having magnetic fluxes in opposite direction within the gap. The voice coil assembly includes a slab, a coil and a suspension unit, wherein the slab is used for being attached to a panel and the coil is immersed within the gap. The positioning assembly is used for supporting and positioning the magnet assembly and the voice coil assembly. When electric current flows through the coil, the voice coil assembly generates a motion in a direction vertical to the magnetic fluxes so as to excite the panel to generate flexural vibration and radiate sound.
