Embodiment Construction

[0022] An automated intelligent TWS bluetooth earphone testing system of the present invention comprises:

[0023] The computer (Personal Computer, PC) is pre-installed with host computer software that realizes human-computer interaction and communication between the computer and the Bluetooth headset to be tested. The host computer software controls the Bluetooth to be tested by sending Bluetooth instructions (based on the Bluetooth core5.1 protocol). In the working state of the earphone, the computer communicates with the bluetooth earphone to be tested through the spp mode. When connecting the spp, it sends the call (mac address) (uuid) rfcomm command. The general uuid is 1101. If you customize the uuid, you can also use The channel number of rfcomm for spp connection. Perform information interaction or issue commands to the headset to control the working status of the headset. The specific command can be defined by the headset designer, or the standardized command of the u...

Abstract

The invention provides an automatic intelligent TWS Bluetooth earphone test system, which comprises a computer in which upper computer software is installed in advance, wherein the upper computer software controls the working state of a Bluetooth earphone to be tested by sending an instruction; two shielding boxes which independently test the Bluetooth earphone in parallel, wherein at least one Bluetooth adapter is arranged in each shielding box, and the computer communicates with the Bluetooth earphone to be tested through the Bluetooth adapters and transmits audio data to the Bluetooth earphone to be tested through the Bluetooth adapters; and two test jigs which are arranged the shielding boxes respectively, wherein each test jig is provided with a plurality of artificial ears and artificial mouths, the artificial ears are used for collecting sound emitted by a loudspeaker of the Bluetooth earphone to be tested, the artificial mouths are used for generating sound to test the microphone performance of the Bluetooth earphone to be tested, and the artificial ears and the artificial mouths are in communication connection with the computer through the upper computer software. The system has higher equipment and personnel utilization rate and test efficiency, and the UPH of production line test is greatly improved.

Description

【Technical field】 [0001] The invention relates to the technical field of acoustic measurement, in particular to an automatic intelligent TWS bluetooth earphone testing system. 【Background technique】 [0002] TWS Bluetooth headsets have set off a wave in the world. Compared with the inconvenience of traditional wired headsets, people are more and more inclined to portable, convenient, small and comfortable TWS, which requires more systematic, professional and accurate testing. Existing test methods are often used to evaluate the simple human ear listening method, or simply evaluate the single performance of the speaker and microphone under test. Generally, the existing Bluetooth earphone testing system can only test a single earphone, which is very inefficient and wastes a lot of time and labor costs. [0003] There is following defective in prior art: [0004] 1. The facilities are too simple, the test is not complete, and many earphone functions are not detected, such as ...
