Abstract: A common plate is formed in a moveable element of a device, the device having an actuator coupled to drive the moveable element. A first plate and the common plate together form a first capacitance, while a second plate and the common plate together form a second capacitance, both of which varies as a function of displacement of the moveable element. A measurement circuit has an input coupled to the first plate, while an excitation voltage source has an output coupled to the second plate. A guard voltage source has an output coupled to a conductive portion of the device. Other embodiments are also described and claimed.

Abstract: An audio speaker having a speaker housing surrounding a back volume that is divided into a rear cavity behind a speaker driver and an adsorption cavity separated from the rear cavity by a permeable partition, is disclosed. More particularly, the adsorption cavity may be defined between the speaker housing and the permeable partition, and may be directly filled with adsorptive particles to adsorb gas during sound generation. The permeable partition may allow the gas to flow between the rear cavity and the adsorption cavity, and may retain the adsorptive particles within the adsorption cavity. Other embodiments are also described and claimed.

Abstract: Embodiments of the invention include a micro speaker assembly that has two drivers, each having a separate yoke, set of magnets, voice coil, and acoustic diaphragms. One driver may produce high frequency (HF) sound while the other produces low frequency (LF) sound. The two drivers may be packaged, side-by-side, within the same micro speaker acoustic enclosure. The drivers may have their respective magnet systems physically connected to each other, in order to enhance heat transfer from one to the other. In particular, a thermally conductive portion or bridge may be used to directly join or thermally connect adjacent edges of the yoke portions of the two magnet systems, in order to enhance heat transfer between the first and second micro speaker drivers. Thus, the assembly can handle more power without overheating. Other embodiments are also described and claimed.
