I need a small module or a single chip to handle the music decoding and sound playback in my project. I have seen DFPlayer, but I think there is still room in terms of cost. Or I can solve this part of the design with a single chip for a moment. Isn't it more simplified and cost-effective?
Basically, the sounds being played are uncertain. They could be music, alarms, or some type of operation prompt sound. They are some pre-processed simple voice files in MP3 or WAV format, which can cover the general requirements for sound quality and volume. I think I need some storage space. I don't know if the SD card is suitable for this. It would be even more perfect if the chip had its own independent built-in storage space.
Finally, I may not need an amplifier or a separate power supply, but I do need some speakers.
Could anyone offer some suggestions on this topic?
TI makes a lot of special audio chips but my guess is that the DFplayer is (or is based on) a microcintroller because it has the MP3 decoder and that's done in software/firmware.
Sparkfun have recently come out with breakout board that looks interesting, it's more expensive than the DFPlayer modules but the video makes it look good. I think I am going to buy one and see what it sounds like.
I think this has nothing to do with the target price. It just stems from the intuition of technology. More professional and simple things are easier to apply and the price will also reach an extreme
What you said is correct. Products that are relatively widely used in the market must go through a process of verification, refinement and re-verification. I need to pay attention to this point
TI's audio chips are great, but they tend to be 'big and beautiful'—which often means expensive. I'm looking for something more like the 'small and smart' solutions you'd find in, say, China's Yiwu market.
In fact, the budget is not the issue I need to consider at this stage. It's just that making the product as simple and inexpensive as possible is a problem that needs to be kept in mind from the design stage with a focus on long-term development until the product goes into mass production.
I recently found a chip and just got its user manual, schematic diagram and other materials. It looks very similar to DFPlayer. After I finish reading its technical materials, I plan to get a sample to try next
The inexpensive DFR module's speakers can be rated at 3W, v 0.5W of your (unpriced?) chip. Which may be irrelevant if your product is tiny, and/or uses earphones
