Abstract: An outdoor multifunctional solar energy foldable table includes a table plate, a foldable stand connected beneath the table plate, a vertical column for supporting the foldable stand, and table legs fixed to a lower end of the vertical column. The table plate includes an exterior frame with a control panel, an interior frame inside the exterior frame, a wireless charger positioned on a support on an internal side of the interior frame, inclined support tubes that intersect and connect to the internal side of the interior frame, fixed tubes connected to the inclined support tubes to form a framework structure, a photovoltaic chip positioned on the framework structure, a glass table plate for covering the photovoltaic chip, and a circuit cable box connected to a fixed tube. The circuit cable box includes fourth generation wireless network transmitter/receiver modules, a storage battery, a control chip, and direct current/alternating current circuits.

Abstract: A buzz detecting method and a buzz detecting system are provided for testing whether an under-test sound playing device generates a buzz while playing sound. By an application program module, plural under-test sound signals from the under-test sound playing device are converted into plural under-test frequency-domain signals corresponding to the under-test sound signals through Fourier transform. Moreover, the application program module calculates plural under-test noise ratios corresponding to the frequencies of respective under-test sound signals according to respective under-test frequency-domain signals. After the plural under-test noise ratios are compared with plural standard noise ratios from a standard sound playing device, the application program module may automatically judge whether the under-test sound playing device generates a buzz while playing sound. Since the testing procedure does not need to be implemented by the trained testers, the overall efficiency is largely enhanced.
