Abstract: A multi-way speaker array is disclosed that includes rings of transducers of different types. The rings of transducers may encircle the cabinet of the speaker array such that the speaker array is rotationally symmetric. The distance between rings of transducers may be based on a logarithmic scale. By separating rings of transducers using logarithmic spacing, denser transducer spacing at short wavelengths is achieved while limiting the number of transducers needed for longer wavelengths by spacing them in larger and larger logarithmic increments. Transducers with overlapping frequency ranges may be used in the speaker array to avoid initial dips or shortfalls in directivity for corresponding beam patterns.

Abstract: A first electronic device includes a first coil that is operative in at least two modes. In a first mode, the first coil may be utilized to moves a membrane to produce one or more sound waves, register movement of a membrane to detect one or more sound waves, or generates one or more haptic outputs. In the second mode, the first coil may be used to inductively transmit power to and/or inductively receive power from a second coil included in a second electronic device. In various cases, the second coil may be a dedicated inductive power transmission coil. In other cases, the second coil may be capable of multimode operation similar to the first coil.
