Our assignment was to design a passive phone amplifier using Fusion360. This phone speaker is designed specifically for the iPhone 8+
Step 1: Sketch a 200 mm x 50 mm 2-point rectangle.
Step 2: Extrude the rectangle 35 mm.
Step 3: Use the chamfer command on the two short sides of the rectangle, making the chamfer distance 30 mm.
Step 4: Sketch a slot on the top of the speaker towards the back. The slot should be 90 mm long and have side arc radii of 9 mm.
Step 5: Using the extrude command, cut the slot 25 mm into the speaker.
Step 6: On the front of the speaker sketch an ellipse with a horizontal radius of 50 mm and a vertical radius of 25 mm. Next, sketch a line down the midpoint of the front surface. Then mirror the ellipse over the line so their are two equidistant ellipses on the front of the speaker.
Step 7: Sketch a slot on the inside of the cut slot on the side closest to the side that the ellipses are on. The slot should be 20.5 mm long and have arc radii of 2.25 mm. Repeat the steps taken to mirror the ellipses using the slots on the inside of the speaker to make two identical slots equidistant from each other.
Step 8: Use the loft command to cut holes between the inner slots sketched in step 7 and the outer ellipses sketched in step 6.
Step 9: Using the fillet command, round the edges of the ellipses on the front of the speaker to a distance of 2.5 mm. Then fillet the top slot of the speaker to a distance of 5 mm.
Step 10: Finally, fillet the long edges on the top of the speaker to a distance of 5 mm. Then fillet the chamfered edges to a distance of 5 mm.
