<p>Disclosed are a speaker unit and portable data terminal that accomplish miniaturization, a thinner form factor, and high acoustic pressure. A speaker unit is equipped with a yoke (1), which has a rectangular outer shape viewed from above, a magnet member (2), which is disposed on the yoke (1) and magnetized so that the N pole and S pole are aligned in one direction at the top surface, a coil (3), which is disposed on the top surface of the magnet member (2) with a space between, a diaphragm (4), which is mounted on the coil (3), and a frame (5), which supports the diaphragm (4). The yoke (1) includes a mounting part (6) protruding upward at the outer circumference thereof, to which the frame (5) is mounted. The mounting part (6) has cutouts (7) at the center of the mounting part (6), intersecting the aforementioned one direction.</p> |
