Patent number: 11733378Abstract: The present disclosure provides a detection system and a detection method. The microphone of the detection system receives the response signal formed according to the shape of the sealed cavity. The conversion unit transfers the response signal in the time domain to the frequency domain signal in the frequency domain. The calculation unit obtains every frequency value corresponding to the frequency gradient being zero of each frequency waveform which is chosen of the response signal. The average unit averages every frequency value corresponding to the frequency gradient being zero of each chosen frequency waveform into the average frequency value and outputs an average frequency value. The determination unit determines whether the average frequency value is located in the corresponding frequency tolerance range, so that the wearing status of the in-ear earphone is confirmed.Type: GrantFiled: February 11, 2022Date of Patent: August 22, 2023Assignee: COMPAL ELECTRONICS, INC.Inventors: Chung-Han Lin, Yueh-Hsiang Chen, Kun-Chi Pan
