SPEAKER (without tolerance) and the gap between the shell to take 0. 1mm/ unilateral, sound chamber part should be bone seal, resonant cavity depth 0. 7-1. 0mm. SPEAKER, and between the shell using sponge compression. when the electronic motor is fixed, the bone is often killed by the bone, but the bone bit can not be placed in the center of the motor. It should be separated from the outer edge of the motor, and the clearance of the pendulum head is more than 0. 4. screw head part structure sketch: sink the thickness to do 0. 8mm above, screw head thickness space more than 0. 8, the lid if use TPE material must do 0. 5mm above, if the thickness is insufficient, can do 0. 3mm PVC. Bottom flip: bottom flip: Directions: the upper and lower shell: shell and the bottom shell with matching rabbet do 0. 2mm, do double check (see Figure 1 and flip); 10 interface to do the 2 screws, a rotating shaft end at least to do a screw, if you really can not do the screws, must do as much as possible buckling. The middle part is unilateral to do 1 to 2 buttons. Icon: key and C key: shell surface and shell surface generally do, it is necessary to do more in the 0. 1mm shell, C shell thickness of a key part of glue should ensure th
