    Abstract: Aspects of the subject technology relate to electronic devices having speakers and airflow sensors for the speakers. In one or more implementations, the airflow sensor may be formed, in part, by a mesh structure that spans a port in a housing of the electronic device. In one or more implementations, the airflow sensor may be formed, in part, by an exposed portion of a conductive trace of the speaker.

    Abstract: Aspects of the subject technology relate to electronic devices having sensors such as pressure sensors. A pressure sensor may be integrated into an audio component of an electronic device such that the pressure sensor is fluidly coupled to an environment external to a device housing via at least a portion of an internal cavity of the audio component housing. The audio component housing may include an opening. The pressure sensor may be mounted adjacent to or within the opening. The opening may be sealed to prevent passage of gas or liquid through the opening. The pressure sensor may be integrally formed with an inner wall of the audio component housing. The audio component may be a speaker or a microphone.

    Abstract: The described embodiments relate to an electronic assembly that includes multiple varied electrical components. In some embodiments, the electronic assembly can include electrical components susceptible to electromagnetic interference (EMI). In one particular embodiment, an antenna can be positioned along an exterior surface of an enclosure of the electronic assembly and another electrical component can be disposed within the enclosure. When the other electrical component is a speaker component, a port or opening for emitting audio output can be protected from EMI by surrounding the port with a conductive gasket that includes a closed cell foam substrate wrapped in an electrically conductive fabric. In some embodiments, the closed cell foam substrate defines a number of perforations that are plated with an electrically conductive material.

    Abstract: Aspects of the subject technology relate to electronic devices having speakers. An electronic device may operate the speaker to generate audio output at one or more resonance frequencies of the speaker and/or the electronic device. This can allow the electronic device to generate particularly loud audio outputs while reducing the power consumption used to generate those audio outputs. In order, for example, to help ensure that the audio output is generated at the resonance frequencies, the electronic device can determine the resonance frequencies prior to generating the audio outputs. For example, the electronic device may determine resonance frequencies by obtaining one or more electrical characteristics of an electronic component while operating the speaker, and determine the resonance frequencies based on the obtained electrical characteristics.
