To create a simple audio test HMI project in minutes
- Convert the audio file to wav format in VideoBox
- Add audio wav file in the resource panel
- Add two buttons for PLAY and PAUSE and configure the background of these two components
- Add audio component, initial the audio en parameter as "0" and set audio ID as "0"
- Coding "wav0.en=1" for PLAY button Touch Release Event
- Coding "wav0.en=0" for STOP button Touch Release Event
- Compile and upload the project
*Note: To Be sure that the Nextion HMI display working properly, please increase 0.5A for the working current of the display power supply. For example, The official power supply recommendation of NX4827P043-011R is DC 5V/1.0A, if you would like to use the Nextion BOX speaker, the input current should be increased from 1.0A to 1.5A to ensure working stability.

The sound quality is reasonable given its small size. I’m using it to provide a simple melody during system boot-up and for audible alerts during system faults. Overall, I'm pleased with my purchase.
i used this product for sound alert.
maybe better put in some short circuit protection in the RX and TX system. or fail or error in conection with microcontroleitor.
my suggestion is because three screens of the basic model have damaged the tx system when connecting it to microcontrollers,
for this reason the screen receives data but does not send it,
we have made the same connection with other nextion screens and the same controller and it works normally sending and receiving data. but only on these three screens of the basic model. They receive but do not send data despite having done multiple tests.
If you could provide us with a solution. (change a component of the screen).
I would be very grateful.
I just didn't expect that good sound from something so small.
Het is een mooi compact luidsprekertje dat een duideliijk signaal kan laten horen. Voor zo'n klein luidsprekertje is de geluidskwaliteit van muziek best wel goed. Ik gebruik hem vooral om een signaal te geven dus een wav. bestandtje met een enkele toon.
I used this speaker for an prototype display in our test vehicle. Sound quality is good. It would be very good, if itead provide a better technichal drawing, height of mountings is not given.
