Abstract: Examples herein relate to ambient noise level detection. For instance, in some examples an electronic device includes a cooling resource and a processor resource to alter an operational speed of the cooling resource from an initial operational speed to a first altered operational speed, detect an ambient noise level, compare the ambient noise level to a first noise threshold, and restrict the operational speed of the cooling resource to be less than the initial operational speed.

Abstract: An example device comprises: a surface-type sensor to detect a type of surface on which the device is located; a proximity sensor; and a processor. The processor is to: in response to detecting, using the surface-type sensor, that the device is located on a soft-type surface, increase noise output of the device; and, in response to detecting, using the proximity sensor, that a plurality of persons are proximal the device, decrease the noise output of the device.

Abstract: In an example, a speaker device may include a first transducer and a second transducer. The first transducer may include a first diaphragm, a first magnetic circuit, and a first voice coil disposed in a magnetic gap of the first magnetic circuit to cause vibration of the first diaphragm. The second transducer may include a second diaphragm, a second magnet circuit, and a second voice coil disposed in a magnetic gap of the second magnetic circuit to cause vibration of the second diaphragm. Further, the speaker device may include a magnetic plate having a first surface coupled to the first transducer and a second surface coupled to the second transducer. The first surface is opposite to the second surface.

Abstract: In example implementations, a mobile device is provided. The mobile device includes a camera, a microphone, a metallic housing and a privacy cover. The metallic housing encloses the camera and the microphone. The metallic housing includes a privacy cover storage area. The privacy cover is removably coupled to the privacy cover storage area. The privacy cover is dimensioned to cover the camera and the microphone and stay within a bezel of the metallic housing.

Abstract: A light source module for generating polarized light includes a light emitting element, a reflector, and an optical element. The light emitting element generates a light ray, and the reflector reflects the light ray towards the optical element. The optical element includes a light splitting face and a reflection face. The light splitting face receives the light ray, and an angle between the light splitting face and the incident light ray is at about a Brewster's Angle. After the light ray is irradiated to the light splitting face, the light ray is divided into a refraction light and a reflection light. The reflection face reflects the refraction light, and the reflection face is substantially perpendicular to a path of the refraction light. Therefore, a light source with a high degree of polarization is realized by a design of the light splitting face and the reflection face.

Abstract: A polarizer-alignment dual function film. The film comprising an optically anisotropic material layer having a plurality of strips integrally formed thereon. The strips provide an alignment function for aligning the liquid crystal molecules while the optically anisotropic material provides a polarization function such that the two functions can be integrated into a single-layered film.
