Therefore, music played by the mobile phone player can be sent out through the loudspeaker of the hand microphone. Therefore, the hand microphone accessory can continuously play the designated audio file, and the hand microphone can be placed in various environment boxes for testing. The corresponding hand microphone audio link multiplexes the gain of the original loudspeaker link (the gain is known), and the amplitude of the sound source can be calculated according to the rated power of the hand microphone loudspeaker; different application scenes are covered by making different audio files (pink noise) to achieve the effect of aging test.
