The processor outputs a DSD audio signal to the DSD audio playback circuit in response to triggering performed by a user. The DSD audio playback circuit is configured to process the DSD audio signal, generate an alert tone based on a current scenario, and superpose the processed DSD audio signal and the alert tone. The headset jack is configured to connect to a headset and play the superposed audio signal and alert tone using the headset.
