What Are the Two Speaker Types?
Mylar speakers (polyester-film diaphragm) are ultra-thin drivers built for compact and portable devices. Box speakers use a paper/polymer cone mounted in an enclosed cabinet, producing fuller bass and higher power handling for devices with more physical space.
SHENGQUN manufactures both as an OEM / ODM supplier: mylar speakers from 8mm–57mm with IP55 waterproof film options, and box speakers from 3W–200W, 2Ω–8Ω, with paper-cone natural tone.

| Property | Mylar Speaker | Box Speaker |
|---|---|---|
| Diaphragm | Polyester film (mylar) | Paper / coated cone |
| Typical size | 8–57 mm | Larger, cabinet dependent |
| Power handling | Low (micro-speaker class) | 3W–200W |
| Impedance | Custom per model | 2Ω–8Ω |
| Bass response | Limited (thin enclosure) | Better (enclosed cabinet) |
| Waterproof options | IP55 film available | Depends on construction |
| Best for | Phones, wearables, compact devices | TV, multimedia, audio systems |
How to Choose
- Measure the space. If depth and size are tight, a mylar speaker fits.
- Set the acoustic goal. Need bass and output volume? Prefer a box speaker.
- Check enclosure volume. Box speakers need a cabinet to sound their best.
- Consider moisture. For washable or outdoor areas, check IP options.
- Validate with samples. Test both types in your real device.
Frequently Asked Questions
Can a mylar speaker replace a box speaker?
Only when the space and output targets are much smaller; box speakers provide higher power and better bass, so the choice depends on your enclosure and acoustic budget.
Which type is better for a smart device?
For slim portable devices, mylar speakers are common; for devices with room for a cabinet, box speakers deliver better audio.
Does SHENGQUN make both types?
Yes, as an OEM / ODM supplier we produce both mylar and box speakers; see Mylar Speaker and Box Speaker.
Can I get samples to compare?
Yes. Share your device drawings and acoustic target, and we can supply samples of both types for a side-by-side test.
