Abstract: The present disclosure discloses a method and an apparatus for testing a speaker, an electronic device and a storage medium. A specific implementation includes: obtaining first audio data recorded by a microphone integrated with the speaker in ambient white noise; analyzing the first audio data to derive a first analysis result; and determining whether there is a defect in the microphone according to the first analysis result. Hence, these allow for testing a completed set on an assembled speaker to ensure the consistency of a microphone test and improve the accuracy of the test result.

Abstract: A truck rear lamp includes a housing, a unitary circuit board, a main lamp shell, a side lamp shell and a license-plate lamp shell combined together. The circuit board has a front side provided with plural main LEDs and a rear side fixed with a connecting seat having an outer end disposed with a side LED, further having plural license plate LEDs arranged at a location near the bottom of a rear side, and the license plate LEDs has one side provided with a reflecting mirror. The unitary circuit board received in the housing is installed thereon with LEDs respectively located at different locations for carrying out different-purpose lighting and warning, able to save time and labor in assembly and lower producing cost.
