Embodiment Construction
[0031] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0032] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or intervening components can also be present. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or there may be intervening components at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

The invention discloses a microphone testing method, and the method is applied to a microphone testing system and comprises the following steps: plugging a microphone sound hole of a to-be-tested microphone by using a shielding film; covering the to-be-tested microphone and the loudspeaker together through a shielding case to form a closed space; inserting the to-be-tested microphone into a probeon a carrier plate; enabling an industrial personal computer to send a signal to a power amplifier board and making a sound through the loudspeaker; enabling the to-be-tested microphone to convert thesound into an electric signal, and enabling the test board card to measure the voltage value of the electric signal converted by the to-be-tested microphone; enabling the test board card to feed backthe measured voltage value to the industrial personal computer, enabling the industrial personal computer to compare the voltage value with a normal value, and if the voltage value is greater than the normal value, determining that the loop breaking problem occurs. The testing efficiency is high, the testing integration degree is high, space and manpower are saved, automatic testing is achieved,dependence on manpower is greatly reduced, timeliness is high, operation is easy, and cost is low. The invention further discloses a microphone testing system, electronic equipment and a storage medium.
Description
technical field [0001] The present invention relates to the testing field, in particular to a microphone testing method, system, electronic equipment and storage medium. Background technique [0002] At present, with the increasing update of technology, the integration of mobile phones and other consumer products is getting higher and higher, and the requirements for overall space utilization are getting higher and higher. At this time, it is necessary to optimize the integration of PCBA to meet the new test requirements. Among them, the voice quality of the microphone has always been the focus of mobile phones and other products, and the ring break test, ICT and FCT are the basic test contents of PCBA. Therefore, a test solution that integrates these two functions becomes a new requirement. Most of the microphone loop detection on the market is done by using an electroacoustic test system (Sound Check) or an audio analyzer (AudioPrecsion, referred to as AP). ICT (Online ...
