Microphone performance detection method and system

Abstract

The invention relates to the technical field of audio equipment, in particular to a microphone performance detection method and system. The method comprises the following steps: receiving a USB input signal; converting the USB input signal into a first TTL (Transistor-Transistor Logic) serial port signal; converting the first TTL serial port signal into an analog signal; amplifying the analog signal to generate an amplified signal; transmitting the amplified signal to an electric switch to form a test signal; and transmitting the test signal to the microphone so as to carry out a performance test. According to the microphone performance detection method and system provided by the invention, audio frequency does not need to be used when the performance of the microphone is detected, so that noise pollution cannot be generated, a silencing environment does not need to be provided, interference of other sounds in the environment is prevented, and detection is more accurate and environment-friendly.

Description

technical field [0001] The present application relates to the technical field of audio equipment, in particular to a microphone performance detection method and system. Background technique [0002] With the advent of the smart age, people's demand for smart products is becoming more and more urgent. The normal use of smart products often requires the use of voice recognition scenarios. However, the normal use of voice recognition functions inevitably requires the use of microphones or microphone arrays. , the performance of the microphone is an important factor affecting the effect of speech recognition, so it is particularly important to test the performance of the microphone before leaving the factory. [0003] At present, the main test methods for microphone performance include manual detection and automatic detection. In manual detection, the tester listens to the sound recorded by the microphone array to be tested, and judges whether the sound is normal to determine th...

Problems solved by technology

[0005] In order to solve the traditional technology, when the performance of the current microphone is tested, the sensitivity and consistency of the microphone acquisition circuit cannot be guaranteed due to the large quantity during mass production.

In addition, the existing test methods need to use audio, which produces noise pollution, and is also easily disturbed by external sounds, and will also interfere with each other during batch testing. The application provides a microphone performance testing method and system
