Abstract: An acoustic enclosure has a housing at least partially defining an acoustic chamber for an acoustic radiator. The housing defines an acoustic port from the acoustic chamber to a surrounding environment. An acoustic resonator has a first resonant chamber and a second resonant chamber. The acoustic resonator also has a first duct to acoustically couple the first resonant chamber with the acoustic chamber and a second duct to acoustically couple the second resonant chamber with the first resonant chamber. An electronic device can have an electro-acoustic transducer. Circuitry in the electronic device can drive the electro-acoustic transducer to emit sound over a selected frequency bandwidth. Damping provided by the first and the second resonant chambers can de-emphasize one or more frequencies and/or extend a frequency response of the acoustic enclosure to improve perceived sound quality emitted by the electronic device.

Abstract: A transducer assembly including a stiffener plate having a first side and a second side; a voice coil coupled to the second side of the stiffener plate; a magnet assembly positioned along the second side of the stiffener, the magnet assembly operable to produce a magnetic field that causes a movement of the magnet assembly relative to the voice coil; and a spring suspending the magnet assembly from the stiffener plate such that the movement of the magnet assembly drives a movement of the stiffener plate.

Abstract: An input device, such as a stylus, can include a main body comprising a main body connector for connecting to a charger to charge a power source of the stylus. A separate functional end module is removable from the main body to expose the main body connector. The functional end module includes a functional component and a module connector that communicates with the main body via the main body connector. Various different functional end modules can be interchangeable to provide a variety of distinct features to the stylus.
