Mini speaker with phone clip - KCX_BT010

1. Introduction:
The built-in speaker on my phone is too weak, so I made a small speaker with a phone clip. It enhances
the immersive experience when watching videos, with deep bass and detailed vocals . The speaker
diagram is as follows: It's relatively simple.
2. Core Component
: The KCX_BT010 module, which I bought from Uxin Electronics. I think other stores also sell it, but Uxin Electronics is more expensive.

3. EQ Recommendation:
Since this module does not have built-in EQ adjustment, I recommend the following EQ: The EQ adjuster is the Dolby sound effect built into Xiaomi.
4. Shell Design: Used in SW design, see attachment: 3D.7z independent cavity shell for
mobile phone speaker. Simply close the shell; no sealing is required. There is a reserved space for the passive radiator, but thicker speakers are not recommended; the passive radiator space needs to be sealed. 3-inch speakers are acceptable, but be careful to check if the screws can be removed. If not, the shell will need to be modified. 5. Summary : It is definitely stronger than the phone's built-in speaker. Removing the phone stand and using it as an outdoor speaker is also a good option.
