Microphone test method and system for electronic device

The invention relates to an electronic device testing method and system, in particular to a microphone testing method and system of an electronic device.

At present, the microphone test of the recording device is to record and re-broadcast. When the broadcast is performed, the operator manually judges the recording result of the microphone of the recording device. The staff on the line hears that there is a problem and sends the repair station. If there is no problem, the user continues to run. In the next test, the judgment result is often subjective, and the external factors such as the environment are noisy, which makes the accuracy of the test lower and extremely unscientific. In addition, there is currently no microphone test method and system for testing multiple sets of recording devices at the same time.

Accordingly, it is an object of the present invention to provide a microphone test method and system for an electronic device capable of improving detection accuracy and capable of simultaneously testing a plurality of sets of electronic devices.

Therefore, in the microphone testing method of the electronic device of the present invention, the electronic device has a built-in test program, and the test program includes the following steps: (a) converting a sound collected by the microphone of the electronic device into a sound recording file; (b) If the recording conforms to a predetermined standard, the microphone passes the test if it is met, otherwise the microphone fails the test.

The microphone test system of the electronic device of the present invention comprises a sounding tool and an electronic device; the sounding tool is provided for playing a sound to the microphone of the electronic device; and the electronic device has a storage medium with a built-in test program. The test program converts the sound collected by the microphone into a recording file, and compares the predetermined standard with the recording file. If the recording meets the predetermined standard, the predetermined standard passes the test, otherwise the test fails.

The microphone test method of the electronic device of the present invention can be tested by a plurality of sets of electronic devices, and each group of electronic devices has a built-in test program, and the method comprises the following steps: (a) time-division/simultaneously approaching each of the electronic tools a microphone of the device and playing a sound to provide a microphone for each of the electronic devices; (b) a test program of each of the electronic devices respectively converting the sound collected by the microphone of the electronic device into a recording file; and (c) each The test program of the electronic device compares with the predetermined standard according to the recording file, and if it matches, the microphone passes the test, otherwise the microphone fails the test.

The efficacy of the microphone testing method and system of the electronic device of the invention: 1. Avoiding the problem of noisy environment: the sounding tool is close to the microphone of each electronic device to receive sound at a close distance, thereby avoiding noise interference.

2. Improve the accuracy rate: it is judged by the test program to avoid the problem of inaccurate manual judgment.
