Mobile telephone sound effect testing device and testing method

Abstract

The invention relates to a mobile telephone sound effect testing device, which comprises a processor, an artificial mouth, an artificial ear and an acoustic box, wherein the processor comprises a first test module, a second test module and a control module; the first test module is used for testing an element to be tested which converts electrical signals into acoustic signals; the second test module is used for testing an element to be tested which converts the acoustic signals into the electrical signals; the control module is connected with the first test module and the second test module, and is used for controlling the first test module and the second test module; and the artificial mouth and the artificial ear are arranged in the acoustic box, connected with the processor, and are used for generating the acoustic signals inputted into an acoustic element to be tested and receiving the acoustic signals outputted by the element to be tested respectively.

Description

technical field [0001] The invention relates to a mobile phone sound effect test device and a test method, in particular to an automatic mobile phone sound effect test device and a test method. Background technique [0002] In the manufacturing process of mobile phones, it is necessary to test the acoustic performance of components such as microphones, earphones and speakers. Most of the existing acoustic component detection methods use computers, artificial ears, soundless boxes and other equipment to simulate the working environment of the tested acoustic component, and then use the tested acoustic component to work in the simulated working environment and record The frequency response characteristic of the component under test is displayed by the oscilloscope, and then adjusted accordingly according to the frequency response characteristic of the component. [0003] However, in the above-mentioned existing testing methods, it takes a lot of time to display the acoustic c...

Problems solved by technology

[0003] However, in the above-mentioned existing test methods, it takes a lot of time to display the acoustic characteristics of the component under test through an oscilloscope and make corresponding adjustments accordingly

In actual production, the number of tested components on the production line is huge, and using an oscilloscope to display and adjust them one by one will take a lot of time and cannot meet the needs of the industry
