FAQ

Q1: What is the minimum order quantity (MOQ) for the SM20S022-F 20mm Mylar speaker?

A: The standard MOQ for this 20mm 8 ohm 90dB Mylar speaker is 1,000 pieces. However, Shenghui Electronic understands the need for prototyping and evaluation, so we also accept smaller trial orders and can provide sample quantities for testing before committing to a large purchase.

Q2: Is the IPX7 rating of this 20mm Mylar speaker tested and certified?

A: Yes. The IPX7 rating for this 20mm Mylar speaker is rigorously tested in-house according to IEC standard 60529. Each production batch undergoes sample testing to ensure it can withstand immersion in 1 meter of water for 30 minutes without failure, providing confidence for use in wet environments.

Q3: Can the impedance of this 20mm Mylar speaker be customized?

A: Absolutely. While the standard model is 8 ohms, Shenghui Electronic specializes in customizing acoustic components. We can adjust the impedance (e.g., to 4 ohms or 16 ohms) and other parameters like resonance frequency or connector type to perfectly match your 20mm Mylar speaker application requirements.
