Overview
What this part is
The loudspeaker in the Honor 400 Smart 4G is an enclosed module at the bottom of the phone. It plays your ringtone, alarms, media and speakerphone calls. Water, a drop or a blocked grille can leave it quiet, rattly or silent.
If calls at your ear are fine but the ringtone and media are not, the loudspeaker is usually the fault. Check first that the grille is clean and that Bluetooth is not connected to another device.

The Honor 400 Smart 4G is a budget phone in the Honor 400 range. It is not the same phone as the Honor 400 and does not share its parts.
Professional installation
How a technician fits this part
- Power the Honor 400 Smart 4G off and remove the SIM tray.
- Remove the back cover carefully, using gentle heat if it is glued.
- Disconnect the battery connector first.
- Remove the screws and lift out the old loudspeaker module.
- Fit the new loudspeaker and test ringtone and media sound before closing.
- Refit the back cover with new adhesive and do a final sound check.
Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
FAQ
Frequently asked questions
Will this fit my Honor 400 Smart 4G?
Yes, if Settings › About phone shows Honor 400 Smart. It is made for the Honor 400 Smart 4G only.
Does it fit the Honor 400?
No. The Honor 400 is a different model and needs its own loudspeaker.
Will this fix quiet call audio at my ear?
No. This is the bottom loudspeaker. Call audio at your ear comes from the separate earpiece speaker.
Is it made by Honor?
No. It is a brand new, OEM-quality loudspeaker made to fit the Honor 400 Smart 4G, and every part is tested before dispatch.
Should I fit it myself?
We recommend professional installation. Opening the Honor 400 Smart 4G needs heat, the right tools and new adhesive, and the battery must be disconnected safely.
