Abstract

This invention discloses a testing fixture for semi-finished AR glasses frames, belonging to the field of acoustic testing tooling. It includes a Holder module, a tray module, a probe module, a Nose MIC sealing module, an AP MIC sealing module, and a reference speaker module. The tray module carries and drives the Holder module in and out of the testing station, where it positions and clamps the semi-finished frame.

The reference speaker module outputs the test sound source. This fixture is equipped with a motion control system that collects sensor signals from each module to achieve closed-loop logic control. It can collect acoustic signals from the microphones under sealed and unsealed conditions, convert them from digital to analog, and then analyze and determine the microphone performance using upper-level software. This invention automates the entire acoustic testing process for semi-finished frames, improving upon the defects of unstable sealing and poor wiring contact caused by manual operation.

Description

Technical Field

[0001] This invention relates to the field of acoustic testing fixtures technology, and more particularly to a testing fixture for semi-finished AR glasses frames. Background Technology

[0002] With the rapid development of the AR smart glasses industry, the demand for acoustic performance testing at the semi-finished frame stage continues to grow. Currently, most acoustic testing solutions in the industry focus on individual microphone and speaker performance testing for finished AR glasses devices, while integrated acoustic testing fixtures specifically adapted to semi-finished frames are relatively few.

[0003] The AR glasses frame is a semi-finished product with incomplete assembly. The frame integrates multiple microphones (Nose MIC and AP-MIC) and has FPC cables leading out. Acoustic testing requires collecting acoustic response signals from the microphones under both sealed and unsealed conditions to determine the microphone assembly quality and acoustic performance. Traditional testing largely relies on manual processes for product positioning, FPC cable connection, and microphone hole sealing. Manual sealing suffers from poor clamping force and alignment consistency, easily leading to seal failure or damage to the frame. Manually connecting the FPC cables is prone to misalignment and poor contact, introducing testing errors. Furthermore, the lack of standardized reference sound sources and acoustic noise reduction and vibration damping structures means that environmental noise and equipment vibration can interfere with the acoustic acquisition results.

[0004] Existing single-unit testing fixtures can only test a single microphone independently, and cannot simultaneously complete sealed-to-unsealed comparison tests of multiple microphones. The testing process is scattered and has a long cycle time. The fixtures lack automated closed-loop control that links each station, resulting in a lot of human intervention by operators. The consistency and efficiency of testing cannot meet the requirements of mass production line testing for large batches.

[0005] Therefore, a highly integrated automated test fixture is needed to achieve integrated automated testing of semi-finished frame positioning, electrical connection, microphone sealing switching, acoustic excitation and signal acquisition. Summary of the Invention
