Nordic Thingy 52 Speaker Hardware Datasheet

[samdaly]

I am trying to find the hardware datasheet for the speaker on the Nordic Thingy 52 - can someone help point me towards it? 

My end goal is to learn about the characteristics of the speaker so I can maximize the volume (Sound Pressure Level) of a .5 second tone I want my device to emit. I can change the frequency to meet the existing nature of the speaker, but hoping for knowledge on the speaker to make that choice.

Hi

The speaker on the Nordic Thingy:52 is a 15x11mm Rectangle mini speaker (Part No.: BMS1511F-11C-08H03P LF) from BeStar Technologies. Here is the link to the product page, and attached you can find the datasheet.

Best of luck and regards,

Hi Simon - Thanks for your help/response. We are trying to find the Wattage of the speaker/amplifier at maximum volume. If it matters, we are trying to play a simple square wave at ~1100Hz. Can you help us with that? I looked at the spec sheets and I couldn't find any information about the power output of the amplifier circuit. (Our goal is to make a .5s beep sound as loud as possible)

Hi

The product page I linked to informs that the speaker has a rated power of 0.5W and a maximum power of 1.0W. If you need more specific details, I think you'll have to contact BeStar Technologies. You can check out our GitHub page for the Thingy:52 source code for BLE services like the sound service and drivers, etc.

Best regards,

Simon
