Abstract

The present invention provides a multi-channel microphone-based acoustic performance testing device and method, including a probe card tooling, a signal switching circuit board, and a test case, wherein the probe card tooling is used to transmit performance signals of several microphones to be tested to signal Switching circuit board; signal switching circuit board, used to transfer the performance signals of several microphones to be tested transmitted by the probe card tooling to the test case in batches; the test case is used to test the received performance signal, and obtain The performance of each microphone under test. The present invention can solve the problems of low efficiency and high cost of current microphone testing.

Description

technical field [0001] The present invention relates to the technical field of microphone testing, and more specifically, to a multi-channel microphone-based acoustic performance testing device and method. Background technique [0002] At present, the laboratory tests the performance of the microphone, using a test machine simplex station test, which can only test one lap at a time, such as figure 1 As shown in the figure, when performing a performance test on the microphone, only one circle of microphones on the probe card tooling can be tested at a time. figure 1 The shown probe card tooling 1' can hold 24 microphones, and the probe card tooling 1' is used to place the microphones to be tested, wherein the microphones to be tested are arranged in a circle and fixed on the probe card tooling 1', 24 The signal of the microphone product is transmitted to the test box 3' through the signal transfer PCB2' and the signal line to test the acoustic performance of the microphone, ...
