This electret microphone module is a high-quality amplifier. It has a single/dual input of 20dB. This is useful in recording sounds, applicable to portable audio devices such as laptops, cell phones, and handheld computers.
A very powerful and easy to use sound module.
TPA6120 High Fidelity Stereo Headphone Amplifier Module
This slim little board has a class D amplifier on board that can drive 2 channels of 4-8 ohm impedance speakers at 20W each.
This module is based on the MEMS SPH0645LM4H microphone with I2S interface. It is useful for most detection and recording applications thanks to the 50Hz - 15KHz range.
This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT. To keep the breakout small and simple, we only added a 3V voltage regulator (the microphone requires 3.3V DC) and filter capacitors.
The buzzer can be used in your Arduino development plots to generate sounds at different frequencies. This device can play a wide range of frequencies. It's ideal to alert you that a particular process has ended, for example, the completion of tea making by an automaton.
PDM is a little like 1-bit PWM. You clock the mic with a 1 MHz - 3 MHz clock rate, and on the data line you'll get a square wave out that syncs with the clock. The data line with be 0 or 1 logic output, with the square wave creating a density that when averaged will result in the analog value out.
