Abstract: The disclosure relates to an audio device that includes a diaphragm having a graphene material, such as a graphene flake, that is incorporated into a base material. The audio device may form part of a speaker device, a microphone device, or a headphone device. The concentration of the graphene and/or a size of the graphene flakes may be varied throughout the diaphragm to define a stiff center portion and a flexible portion that surrounds the center portion.

Abstract: Asymmetrically strengthened glass articles, methods for producing the same, and use of the articles in portable electronic device is disclosed. Using a budgeted amount of compressive stress and tensile stress, asymmetric chemical strengthening is optimized for the utility of a glass article. In some aspects, the strengthened glass article can be designed for reduced damage, or damage propagation, when dropped.

Abstract: Glass articles having a base layer formed of glass and having a first compressive stress, an adjacent compression layer formed in the glass and having a second compressive stress, and a witness layer formed in the glass adjacent the compression layer and having a third compressive stress. The first, second and third compressive stresses all differing from one another. The witness layer also having a higher index of refraction than an index of refraction for the base or compression layers. Methods for manufacturing and methods of quality control that include the use of the witness layer are also disclosed.

Abstract: A material testing apparatus and methods of testing material are disclosed. The material testing apparatus may include a support ring contacting a test material and a moveable contact component positioned adjacent to the support ring. The moveable contact component may include a substantially curved contact surface comprising a radius-varying curvature profile formed between a center and a perimeter of the substantially curve contact surface. The curvature profile may be based on a predetermined deflection-force profile specific to the test material. Additionally, the curvature profile may also be based on the material characteristics of the test material, the physical characteristics of the test material, the physical characteristics of the support ring and/or a testing process performed on the test material.

Abstract: Asymmetrically strengthened glass articles, methods for producing the same, and use of the articles in portable electronic device is disclosed. The asymmetrically strengthened glass articles include glass articles having a deeper compressive stress layer in a thicker portion of the glass article. Using a budgeted amount of compressive stress and tensile stress, asymmetric chemical strengthening is optimized for the utility of a glass article. In some aspects, the strengthened glass article can be designed for reduced damage, or damage propagation, when dropped.

Abstract: Components of an electronic device, such as glass articles, are susceptible to breakage, especially in regions where machining a glass article has created flaws. Chemical strengthening can be performed to create deeper compression layers at regions of a glass article that have been machined, include and/or are adjacent to an edge feature, have greater surface roughness, and/or have more or deeper cracks.
