Abstract: Wedge shape headphone structures are disclosed. Wedge shape headphone structures can be constructed using plastics, metal, glass, or wood, which assembled a smooth tapered narrow audio outlet channel. The housing structures include two housing component to encompass a speaker unit and a conductor to transmit audio signals to the users. With the shape of narrowing size towards a pointed end, the audio signals can be transmitted to the ear canals in a more effective way and provide a better wearing experience to more people. A coating material can be added to tapering area of the housing structure.

Abstract: Techniques are disclosed for improving bit slice placement and wiring. Some embodiments include swapping cells to improve routing. An alternative embodiment includes copying wiring from a first bit slice to a second bit slice. Another embodiment includes copying blocks or cells from a first bit slice to a second bit slice. Further, the wiring from the first bit slice may be copied to the second bit slice.
