Fixtures are crucial for consistent measurement data. We design dedicated mounting modules for MEMS microphones, speakers, and mobile device components.
Customized design structure: Whether it’s TWS earphones, smart glasses, or MEMS microphones, etc., it can perfectly fit the positioning according to the appearance, improving positioning accuracy and stability.
Reduced assembly errors: One-step positioning and assembly significantly that it can reduce the cumulative errors caused by assembling multiple workpieces.
Low-reflection geometry structure: To eliminate the internal standing waves and echo interference which can restore truly the product’s purest frequency response curve.
Common modular design: The design adopts a modular approach. For the future product upgrades it will only replace the certain fixture modules without the whole fixture redesign that it can reduce subsequent development costs.
Flexible configuration: Combining 3D printing or precision CNC machining. Whether it is manual or automatic fixtures, and it can quickly meet customer needs.
The AOP acoustic test fixture is a specialized fixture which is used to measure the acoustic overload point (AOP) of microphones (especially MEMS microphones widely used in smartphones and headphones).
To support the MEMS MIC of the flex board and MEMS MIC component.
Dimension: W 280 × D 150 × H 159 mm
Frequency Response: 20 ~ 8 kHz / 94 dBSPL & 20 ~ 8 kHz / 140 dBSPL
THD: 1KHz < 0.1% for 120~130 dBSPL
The test fixture is a customized fixture which is used to measure the audio test items (ex: Sensitivity, FR and THD) for the digital MEMS MIC board product.
Reference microphones place on the fixture all the time; Easy to adjustable the down-press force
Quick and convenient test cable connection; Real time monitor output signal & environment noise
Independent EQ for sound source, avoid different FR result at different position; Reduce FR deviation on different fixture
Easy to do speaker calibration to 94dB; High stability fixtures (GR&R<5%)

Surround sound field test fixture is the directional fixture, and it has two design-type. One is for 180-degree vertical side and the other type is for 360-degree horizontal size. It can in-stall sound source or reference microphone to support the directional verification test.
Angle: 180 degree SPK Arc Vertical Jig fixture to support -80 ~ +90 degree; 360 degree SPK Arc Horizontal Jig fixture to support 0 ~ 360 degree; A sound source is for 10 degree, and the distance between the sound source and the center is 1 meter
Weight: 180 degree SPK Arc Vertical Jig fixture 44 kg (14 kg for without SPK Arc Jig, 10 kg for fixed support fixture and 20 kg for base plate jig); 360 degree SPK Arc Horizontal Jig fixture 41 kg (12 kg for without SPK Arc Jig, 9 kg for fixed support fixture and 20 kg for base plate jig)
Dimension: 180 degree SPK Arc Vertical Jig fixture W 1500 × D 1100 × H 2520 mm (Folding size: W 1500 × D 1100 × H 1525 mm); 360 degree SPK Arc Horizontal Jig fixture: The height can adjustable from 80cm to 120cm
Other features: 360 degree SPK Arc Horizontal Jig fixture is include 4 sets, and 1 set for 90 degrees; 180 degree SPK Arc Vertical Jig fixture can support two rotated methods. One is that the test turntable can drives the fixture, the other is that the test turntable rotates by itself; Easy to assembly with hand-tight fixing screw; To support install sound source and reference microphone.
無響箱、系統整合與委外量測可以單獨進行，也可以和治具一起規劃，從單一測項到整條產線，都能找到合適的起點。
Five standard models, Internal dimension size from 380 × 280 × 280 mm to 1000 × 1000 × 1000 mm or others, 30–50 dB of sound Isolation ability. Beyond this range, we can create the customized model base on your test requirement. ex: your DUT size, measurement distance and installation limitation space.
We can integrate the professional audio analysis systems which will help you to edit the related audio test sequence. At the same we also can support the automated control integration for the test fixture.
Low-cost measurement and testing for early-stage products that it can help you complete acoustic verification quickly during R&D and catch issues early.
The Reference MIC power supply and data acquisition equipment for acoustic measurement that it can help R&D teams and production lines establish the consistent and traceable measurement conditions.
Multi-material inkjet 3D printing. It can combine the different material properties in a single model and a single print, such as rigid plastics with rubber-like elastomers, or transparent with opaque materials.
