The patent application (Publication Number: US20240022845A1) describes a speaker design comprising a vibrating body with a diaphragm and an edge, a coil attached to the diaphragm, lead wires connected to the coil, a yoke, a frame supporting the diaphragm and housing a magnetic circuit, and an inner terminal for connecting the lead wire. A passage for the lead wire is positioned between the coil and the inner terminal, enhancing the speaker's functionality.

Furthermore, the speaker includes an outer terminal partially outside the frame and electrically connected to the inner terminal. The inner terminal is uniquely shaped to protrude from the frame's inner periphery, optimizing the speaker's performance. Additionally, the yoke features a cutout at its bottom surface, with the inner terminal positioned accordingly. This configuration ensures that the inner terminal partially overlaps with the yoke's cutout in the direction of acoustic wave emission, further improving the speaker's acoustic properties.
