MakerHawk 2pcs Mini Speaker - 3W 8 Full-Range Portable Advertising Speaker Connector (3.3V - 5V)

These MakerHawk mini speakers are compact yet produce clear, full-range sound for their size. They’re easy to connect via the included interface and work well with low-voltage setups (3.3V–5V). Perfect for DIY projects, small electronics, or portable audio devices. Great value for a pair of reliable, mini speakers.

Perfect for an internal pc beeper. Pretty loud too.

I paired this with an M5Stack Atom Lite ESP32 and a MAX98357 DAC/amplifier and set the volume at +12dB by shorting the gain pin to ground. The Atom is running ESPHome. I am driving it with the Piper TTS add-on to Home Assistant. It works great - volume is at a standard voice level and the voice is very clear. Overall it sounds better/clearer than a cell call on speaker with a volume that is similar. Below is the yaml I'm using on the Atom, if that is helpful. Of course your chosen pins may vary. Total cost, $22.50, but I'm using the same Atom for two other purposes - a relay and a smoke detector, so effectively this is very cheap. i2s_audio: i2s_lrclk_pin: GPIO23 i2s_bclk_pin: GPIO19 media_player: - platform: i2s_audio name: ESPHome Voice Announcements dac_type: external i2s_dout_pin: GPIO22 mode: mono

My goodness these things are incredibly loud!

Works well and sounds alright. Nice little test speaker for DIY projects before committing to a nicer one.

These are great little speakers; They are small and compact (you could probably fit them both on an altoids can) but the sound quality is nice; for now I am just messing around with them using an arduino uno but these will eventually end up on a larger project I haven't gotten all the parts for. I've also hooked them up to a small amplifier board I had around and they sound nice.

I bought a variety of compact 8 ohm speakers to evaluate for use with a horn-bell sound module in a model train engine. This one was the smallest and one of the least expensive speakers I evaluated. It certainly didn't look like a traditional speaker. Frankly I was expecting this speaker to perform the worst. But in tests, the speaker performed surprisingly excellent. It surpassed my expectations. A further advantage of the speaker is that it is encased and easy to mount.

These little speakers really have a lot of volume, and more bass than I expected. I am building some LM386 audio amplifiers for an intercom system and had no problem at all getting enough sound out of them. They get too loud before starting to distort. They are a good value.
