    Abstract: An electronic device includes a housing having an opening comprising an audio port and a speaker assembly carried by the device housing. The speaker assembly includes a water ejection system having a diaphragm coupled to a magnetic driver and a mesh that covers the audio port where the diaphragm and the mesh together define an acoustic volume. When a water ejection signal is received at the magnetic driver, the magnetic driver is caused to move the diaphragm in a manner that ejects water contained within the acoustic volume out of the acoustic volume and through the mesh.

    Abstract: An electronic device having a pressure detection system is disclosed. The electronic device may include one or more elements designed to detect pressure exerted on the electronic device. In some embodiments, the electronic device includes a membrane and a detection mechanism, both of which bend in response to a pressure change at the membrane. The membrane may be electrically coupled with a circuit that detects the bending of the membrane and correlates the bending with a pressure change at the membrane. A can may be hermetically sealed with the membrane and surround the circuit to shield the circuit from liquid ingress. In some embodiments, a light transmitter and light receiver are used to detect the bending of the membrane. The light may reflect from the membrane at different angles, based upon a shape of the membrane, and contact the receiving element at different locations, corresponding to pressure change.

    Abstract: An audio speaker having a magnet assembly for directing a magnetic field through a magnetic circuit, and an electrical circuit for carrying an electrical audio signal current through at least part of the magnet assembly, are disclosed. More particularly, a voicecoil in the electrical circuit may be in electrical contact with a magnetic plate of the magnet assembly. The voicecoil may be electrically connected with a speaker driver circuit at least partly through the magnetic plate. Other embodiments are also described and claimed.

    Abstract: A speaker or microphone module includes an acoustic membrane and at least one pressure vent. The pressure vent equalizes barometric pressure on a first side of the acoustic membrane with barometric pressure on a second side of the acoustic membrane. Further, the pressure vent is located in an acoustic path of the speaker or microphone module. In this way, differences between barometric pressures on the different sides of the acoustic membrane may not hinder movement of the acoustic membrane. In one or more implementations, the pressure vent may be acoustically opaque. As the pressure vent is located in the acoustic path of the speaker or microphone module, being acoustically opaque may ensure that the pressure vent itself does not interfere with the operation of the speaker or microphone module.

    Abstract translation: 扬声器或麦克风模块包括声膜和至少一个压力通风口。 压力孔在声膜的第二侧使大气压力在声膜的第一侧平衡大气压力。 此外，压力通风口位于扬声器或麦克风模块的声学路径中。 以这种方式，声膜不同侧面的气压之间的差异可能不会妨碍声膜的运动。 在一个或多个实施方案中，压力通气口可以是声学不透明的。 当压力通风口位于扬声器或麦克风模块的声学路径中时，声学不透明可以确保压力通风口本身不干扰扬声器或麦克风模块的操作。
