摘要: A speaker module includes a frame; a miniature speaker fixed in the frame and comprising a membrane; and an inner wall arranged in the frame for forming an accommodation space for accommodating the miniature speaker therein. The inner wall further includes at least one projecting part. The inner wall includes a flat part on which no projecting part is arranged; and the projecting part abuts against an outer edge of the membrane of the miniature speaker.

摘要: A portable straw, including the limiting component, the adjusting component and the straw body. The said limiting component includes first limiting disc and second limiting disc which are mutually symmetrical and kept at a given gap. Both limiting discs are connected through a cylinder, and the first limiting disc, the second limiting disc and the cylinder are in a same axis, which eliminates the weakness of the prior straws of the environmental contamination, inconvenient carrying and fixed shape.

摘要: A method for determining a characteristic of a direct-gap semiconductor comprises measuring at least one optical constant of a first sample of a direct-gap semiconductor with an optical spectrometer, calculating an estimated value of an optical parameter of the first sample of the direct-gap semiconductor based on fitting the model αg(ln(1+e(hν-Eg)/(pEu))/ln(2))p to an optical absorption curve based on the at least one optical constant, obtaining at least one second value of the optical parameter, and calculating an estimated characteristic of the direct-gap semiconductor from the estimated value of the optical parameter and the obtained second value of the optical parameter. A method for determining a temperature of a direct-gap semiconductor and a system for determining a characteristic of a direct-gap semiconductor are also disclosed.

摘要: An apparatus, for examining an inner ear is provided. An endoscope is provided, comprising a wave guide and an end piece comprising an end window to be placed a first distance from an inner ear, wherein the waveguide focuses light to create a focal plane the first distance from the end window. An optical coherence tomography (OCT) system is connected to a second end of the wave guide and comprises an imaging system connected to the OCT system for generating an image of the inner ear.
