Abstract

The invention relates to an interphone audio function detection device. The interphone audio function detection device comprises a test fixture and an audio control panel. The test fixture comprises apositioning device for fixing an interphone, an adjustment plate for fixing the audio control panel, and a height adjustment handle for controlling the adjusting plate to be lifted. The adjustment plate is located above a positioning device. Through rotation of the height adjustment handle, the adjustment plate can be controlled to move between a detection location and an allowed mounting location. The interphone audio function detection device is low in power and simple in structure and is easy to maintain. Components such as a sound insulation box, an artificial mouth, an artificial ear anda motion mechanism are avoided, a normal test still can be carried out in a noisy environment of a production line, the test cost is reduced, and the test efficiency is improved.

Description

technical field [0001] The invention relates to the field of electronic product detection, in particular to an audio function detection device of a walkie-talkie. Background technique [0002] See figure 1 , after the walkie-talkie is assembled, the audio function test must be carried out, that is, to test whether the audio path between the speaker and the microphone of the walkie-talkie is normal. The current test method is to use an audio analyzer (such as Keithley 2015), an artificial mouth, and an artificial ear. , a signal amplification board, a set of motion control devices (for X, Y, Z axis movement), such as Japan's IAI electric cylinder. Put the walkie-talkie into a sound-proof box, the audio analyzer outputs a signal of a certain frequency, which is amplified by the signal amplifier board and then output to the artificial mouth for sounding. Computer 2 controls the motion device to place the artificial mouth directly above the microphone of the walkie-talkie. The...
