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: 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.
Abstract translation: 本发明的实施例包括具有两个驱动器的微型扬声器组件，每个驱动器具有单独的轭，一组磁体，音圈和声隔膜。 一个驱动器可能产生高频（HF）声音，而另一个产生低频（LF）声音。 两个驱动器可以并排包装在同一个微型扬声器声学封套内。 驱动器可以将其各自的磁体系统彼此物理连接，以便增强从一个到另一个的热传递。 特别地，导热部分或桥接件可用于直接连接或热连接两个磁体系统的磁轭部分的相邻边缘，以便增强第一和第二微型扬声器驱动器之间的热传递。 因此，组件可以处理更多的功率而不会过热。 还描述和要求保护其他实施例。

Abstract: An electro-acoustic transducer has an acoustic diaphragm and a voice-coil. The diaphragm defines a first major surface. A flange extends from the diaphragm in a direction opposite the first major surface. The voice-coil has a first plurality of windings positioned adjacent to the acoustic diaphragm and a second plurality of windings positioned distally from the acoustic diaphragm. The flange overlaps the first plurality of windings. The flange and the windings can be adhesively bonded with each other to form a lap joint. The lap joint can transfer force from the voice-coil to the diaphragm.
