2 new documentation has been added for the CH-101. They are the
1. AN-000209 MOD_CH101-03-01 Retrofit with 45 FoV Horn v 1.1 - which details how you can take a DK-CH101 or a MOD-CH101 board which has a 180 deg FOV cap included, and add on a 45 deg FOV horn on top of the cap to change the CH-101 FOV to 45 deg.
2. AH-10133-045045MR.STEP - this is the 3D STEP file for customers to 3D print their own 45 deg FOV horn.
Enjoy!
Hi Sir,
Is this 45 deg FOV horn can only apply to MOD_CH101 or can it apply directly to CH101 chip ? (since 2 caps make no sense)
I wish there is a horn design have as small FOV as possible that can be applied directly to CH101 chip. (ex. 23 deg FOB)
Is that possible ?
Thanks,
Sam Lin
We also need to decrease the FoV using a horn but it's hard to do it without deep acoustic knowledge. The only option is to change the dimensions in various parameters and test them one by one. It would be very good to have a narrower horn design provided by TDK.
