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.

Detection system and detection method for in-ear earphone

The present disclosure provides a control method for a touch device. The control method of the touch device allows the plurality of pressure sensors to be activated to detect the pressure on the touch position of the touch panel while the capacitive touch sensor is probably invalid and the touch device is abnormal. Therefore, the touch device works continuously when the capacitive touch sensor is probably invalid.
