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 battery detection device. The detection circuit is disposed on the battery and produces an impedance value variation quantity according to a deformation of the battery. The detection circuit includes four connection nodes. The first connection node and the third connection node are connected with the battery. A voltage variation quantity is produced between the second connection node and the fourth connection node according to the impedance value variation quantity. The protection circuit is connected with the second connection node and the fourth connection node. The protection circuit is in an ON state when the voltage variation quantity is greater than or equal to a cut-off voltage. The protection circuit is in an OFF state when the voltage variation quantity is less than the cut-off voltage, so that an operation state of the battery is changed accordingly.
