Abstract: An audio speaker having a suspension system including a surround to support a diaphragm within a frame and to reduce non-pistonic motion of the diaphragm at several resonant frequencies is disclosed. More particularly, embodiments of the surround include a film that undulates in a peripheral direction around the diaphragm and includes several undulations above and below a radial gap between the diaphragm and the frame. Other embodiments are also described and claimed.

Abstract: An acoustic module, such as a microphone or speaker module, includes an acoustic membrane that vibrates to produce acoustic waves and an acoustic cavity through which acoustic waves produced by the membrane travel. A liquid removal mechanism removes liquid from the acoustic cavity. Such a liquid removal mechanism may include the acoustic membrane, heating elements, hydrophobic and/or hydrophilic surfaces, and so on. In some cases, the liquid removal mechanism may remove liquid from the acoustic cavity upon connection of the acoustic module and/or an associated electronic device to an external power source.

Abstract: A magnet assembly for a audio speaker provides a gap through which a voice coil assembly passes. A magnetic member, a yoke, and a pole piece form a magnetic circuit that focuses magnetic energy in the gap. A spider movably supports the voice coil assembly. The spider is coupled to one of the magnetic member or the yoke by forming the one of the magnetic member or the yoke in two parts and joining the two parts with a portion of the spider between the two parts. The spider may be formed from a thin film thermoplastic, such as polyetheretherketone (PEEK), and may be less than 10 microns thick. The portion of the spider that is between the two parts may be shaped such that a portion of the two parts are in direct contact with one another.

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.
