20mm 8Ω 1W Mini Mylar Speaker
91dB High SPL for Smart Devices
Why OEMs Switch to 20mm Mylar Speakers for Compact Devices
Traditional paper-cone micro speakers are bulky, low-SPL, and inconsistent in batch - the mylar diaphragm approach solves all three.
❌ Common 20mm Speaker Pain Points
- SPL below 85dB - alerts get lost in noisy rooms
- THD above 10% - voice prompts sound muffled
- Poor batch consistency - L/R pairing problems
- Weak low-frequency - toy sound effects feel thin
- No vibration tolerance - outdoor doorbells fail fast
- Unstable lead times - supply chain breaks in peak season

Five Engineering Advantages of the 20mm Mylar Speaker
From diaphragm material to assembly process, every detail is optimized for consumer electronics.
91dB High SPL Output
Industry-leading sensitivity in this size class - 1W input delivers room-filling sound for doorbell, alarm, and voice prompt applications.
20mm Ultra-Slim Form Factor
20×5.1H mm compact body fits into tight enclosures - wearable devices, handheld gadgets, and ultra-thin smart products.
F0=940Hz Full-Bodied Mid-Low
F0 reaches down to 940Hz - toy sound effects, learning tablet voice, and electronic piano tone all sound warm and full.
-25~+60°C Wide-Temp Rated
Thermal-shock tested for outdoor doorbell, vehicle-mounted alert, and cold-climate installations - works year-round.
Tight Batch Consistency
Fully automated production line + 100% electro-acoustic test - inter-batch SPL deviation stays within ±3dB for predictable integration.
8Ω Standard Impedance
Standard 8Ω voice coil - no exotic amplifier IC required, plugs directly into mainstream consumer MCUs and audio SoCs.

Frequently Asked Questions
Q1: Is this 20mm mylar speaker suitable for a smart doorbell?
A: Absolutely. 91±3dB SPL keeps the doorbell chime audible from 10+ meters away, 8Ω impedance matches mainstream doorbell controller boards, F0=940Hz gives the alert tone strong recognizability, and -25~+60°C rating handles outdoor winter and summer conditions without issue.
Q2: What is the MOQ and lead time for custom orders?
A: Prototype starts at 500 pcs, standard production at 3,000 pcs, ODM customization at 10,000 pcs. Standard SKUs ship in 3–5 days, regular production in 5–7 days, and ODM projects in 15–20 days. With 50M units monthly capacity, we keep peak-season supply stable.
Q3: How does a 20mm speaker compare to 23mm or 28mm in the same family?
A: The 20mm with 5.1mm thickness is the slimmest option, ideal for ultra-compact enclosures. Its higher F0=940Hz makes voice prompts sound especially crisp. The 23mm and 28mm options have thicker cones and lower F0, delivering warmer bass - choose by enclosure depth and target sound character.
Q4: Can you provide test reports (EMC, reliability, RoHS)?
A: Yes. Every batch ships with a factory load test, thermal-shock, and humidity report. We are ISO 9001 certified, and we support third-party lab verification (SGS, TUV) when required by your regulatory team.
Q5: Do you support OEM/ODM - can we customize wire, connector, impedance?
A: Yes. From 10,000 pcs we offer: diaphragm material, impedance (4Ω/8Ω/16Ω/32Ω), sensitivity bin, wire length, connector type (PH 2.0 / XH 2.54 / JST / Molex), housing color, and printed logo. Engineering selection guidance within 24 hours, datasheet review within 48 hours.
Q6: Is pricing competitive vs. other Asian manufacturers?
A: As a 17-year direct factory with automated lines and centralized raw-material sourcing, we typically price 10–20% below trading companies. Three MOQ tiers give you step-volume pricing. Free samples available - drop your inquiry and we'll arrange shipment within 48 hours.
