Abstract

The invention discloses a microphone detection method and system, and a microphone, and belongs to the technical field of the audio. The microphone detection method is applied to a microphone, and themicrophone comprises at least one pair of audio receiving units; the detection method comprises the following steps: adjusting trigger levels of at least one pair of audio receiving units; acquiringdigital signals output by at least one pair of audio receiving units; and analyzing the digital signals to acquire working states of at least one pair of audio receiving units. By adjusting the trigger levels of at least one pair of audio receiving units, the audio receiving units can send the data signal along a rising edge or a descending edge of a clock signal, the digital signals output by atleast one pair of audio receiving units are analyzed to acquire the working states of at least one pair of audio receiving units, thereby realizing an aim of troubleshooting and positioning the audioreceiving units in fault.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a microphone detection method, system and microphone. Background technique [0002] Based on PDM (pulse code modulation, pulse density modulation) signal characteristics (reference figure 1 ), one DATA interface of the control unit can be connected to two microphone chips (MIC0 and MIC1). Since the DATA pin of the microphone has parasitic capacitance, if the interface of one PDM interface chip is weakly welded or damaged, another good PDM interface chip will be It will maintain the same signal as before in the high configuration (HighZ) state, resulting in the same data of the two PDM interface chips (MIC0 and MIC1). At present, it is difficult to troubleshoot and locate the faulty microphone chip if there are multiple microphone chips with weak soldering, which will affect voice recognition and user experience. Contents of the invention [0003] Aiming at the problem that the...
