Earpiece Speaker With Wire Routing for an Earpiece Speaker Voice Coil |
摘要 |
A wire routing for an earpiece speaker 100 voice coil 110 has a terminal wire 130 having a takeoff angle 134 that is less than forty-five degrees with respect to a tangent 195 of the voice coil at a takeoff point 132. The terminal wire 130 also has a U-bend 136 and crosses a basket rim 160 of the earpiece speaker 100 at a crossing point 163. A length of the terminal wire 130 between the crossing point 163 and a terminal pad 183 is at an angle 156 less than forty-five degrees relative to a tangent 199 of the basket rim 160 at the crossing point 163. This configuration promotes a terminal wire length and geometry that is able to convert stresses to avoid wire breakage due to fatigue failure.
