Multi-channel audio test device and test method

Abstract

The invention discloses a multi-channel audio test device and a test method. The multi-channel audio test device comprises an equipment access module, a control module, an audio signal acquisition module, an audio output module, a storage module and a terminal access module; the audio signal acquisition module is used for acquiring a first audio signal when a to-be-tested device plays a first preset audio through the audio playing interface in a playing test stage; the audio output module is used for playing a second preset audio in an answering test stage, so that an audio acquisition interface of the to-be-tested device acquires a second audio signal; and the terminal access module is used for receiving a control instruction of the terminal to enter a playing test stage, an answering test stage or a reading stage, and in the reading stage, the content stored by the storage module is read and output to the terminal.

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...

Problems solved by technology

However, the audio test of the existing solutions does not have a high degree of device integration, mainly using an external DC source and a sound card to collect audio signals, and the test flexibility and debuggability are poor
