Abstract
Description
technical field
[0001] The present application relates to the technical field of intelligent equipment automatic testing, in particular to a multi-channel audio testing device and testing method. Background technique
[0002] With the current increase in labor costs, more and more factories have begun to deploy automated production lines. In mobile phone audio automated test equipment, most of the audio signal collection work is done using Peripheral Component Interconnect (PCI) sound cards or An external universal serial bus (Universal Serial Bus, referred to as USB) sound card is combined with an external DC power supply to collect audio signals. That is to use the acquisition equipment to collect the sound from the handset and speaker of the mobile phone, and then convert it into a digital signal through a DC source and a sound card to test the audio of the mobile phone.
[0003] In the prior art, a field programmable gate array (Field Programmable Gate Array, FPGA for s...
