Finished earphone testing method and device and earphone manufacturing system

Abstract

The invention provides a finished earphone testing method and device and an earphone manufacturing system, and the method comprises the steps: obtaining the sampling data of a sensor in a testing time period of each operation event through a testing device, and enabling the value of a second filtering parameter to be the current value of a first filtering parameter; for each operation event, the test device performs second filtering processing on the sampling data of the sensor in the test time period of the operation event according to the value of the second filtering parameter, and judges whether a filtering result meeting a set triggering condition of the operation event exists in the obtained filtering results or not; the testing device enables the value of the first filtering parameter in the finished earphone to be the current value of the second filtering parameter; the testing device judges whether an alternative filtering numerical value of which the second filtering parameter is not adopted exists in a plurality of groups of preset alternative filtering numerical values or not; according to the invention, the number of earphones needing to be returned to a factory for disassembly processing in the earphone production process can be reduced, and the yield of earphone products is improved.

Description

technical field [0001] The invention relates to the technical field of earphone testing, in particular to a testing method and device for a finished earphone, and an earphone manufacturing system. Background technique [0002] A Bluetooth headset is a Bluetooth audio device with a variety of sensors (such as sensors for touch sensing, sensors for in-ear detection, etc.). During the production process of Bluetooth headsets, some sensors in Bluetooth headsets are susceptible to differences in assembly process and shell materials The impact of the impact may cause changes in the hardware parameters of some finished products after the shell is installed, and then there will be problems that the accuracy or sensitivity does not meet the actual use requirements. For example, the touch-sensing buttons based on capacitive sensors are easily affected by the length of the traces and coverage. The influence of parameters such as layer thickness and dielectric constant, or the influence...

[0002] A Bluetooth headset is a Bluetooth audio device with a variety of sensors (such as sensors for touch sensing, sensors for in-ear detection, etc.). During the production process of Bluetooth headsets, some sensors in Bluetooth headsets are susceptible to differences in assembly process and shell materials The impact of the impact may cause changes in the hardware parameters of some finished products after the shell is installed, and then there will be problems that the accuracy or sensitivity does not meet the actual use requirements. For example, the touch-sensing buttons based on capacitive sensors are easily affected by the length of the traces and coverage. The influence of parameters such as layer thickness and dielectric constant, or the influence of internal sampling accuracy deviations may affect the sensitivity of the touch response, which is likely to cause false triggering or no response to the triggering of some finished touch-sensitive keys, so it is necessary to When testing the finished product of the Bluetooth headset, pay attention to the working status of the sensor after the shell is installed, and screen the finished product with problems to ensure product consistency and reliability

[0003] In the current bluetooth headset product testing method, only fixed test parameters are used to test the bluetooth headset, and according to the test results, the finished bluetooth headset is directly output as qualified or unqualified, causing a large number of bad prototypes to be returned to the factory for processing
