Abstract: A data transmission system is disclosed. The data transmission system includes at least one signal processing device, at least one conversion device, at least one antenna device, and at least one flexible printed circuit board. The at least one signal processing device is configured to generate or receive at least one data. The at least one conversion device is configured to transform between the at least one data and an optical signal. The at least one antenna device is configured to obtain the at least one data according to the optical signal, and configured to receive or transmit the at least one data wirelessly. The at least one flexible printed circuit board includes at least one conductive layer and at least one optical waveguide layer. The at least one optical waveguide layer is configured to transmit the optical signal.

Abstract: The inventive subject matter is directed to headset audio systems having resonance chambers designed to improve a system's frequency response in certain ranges. Systems of the inventive subject matter include a casing that both holds a speaker driver and creates two resonance chambers. Each resonance chamber vents to ambient air outside the casing, where the length and cross-sectional areas of each vent can impact the system's frequency response. Each resonance chamber is tuned to a resonant frequency to improve the system's frequency response across a range of frequencies on either side of each chamber's resonant frequency.

Abstract: This application is directed to acoustic chambers that can be incorporated into headsets to improve consistency of sound reproduction between a left and right earcup. Headsets, especially wireless headsets, need to hold many different components within the earcups (e.g., batteries, wireless components, etc.). As earcups are required to hold more components, imbalances between left and right can result. For example, a left earcup might hold a battery, while a right earcup holds wireless charging components. Differences between left and right components can ultimately result in sound reproduction inconsistencies between left and right earcups. Embodiments of the inventive subject matter create consistent acoustic chambers for both left and right earcups so that sound reproduction between the earcups is unaffected by components housed within each earcup.
