MAX9812L Amplified Microphone for Measuring Sound The MAX9812 is a sound amplifier specially designed to treat the signal coming from microphones.We can use it together with Arduino to measure sound from a processor like Arduino.When we saw the modules with microphone we commented that, in general, the signal generated is too low to be registered correctly.If we want to be able to measure sounds, we will have to amplify the signal. The MAX9812L has single / dual inputs, fixed gain of 20dB, bandwidth of 400 kHz, low noise and low signal distortion 0.015% THD.There are two models, its supply voltage is 2.7V to 3.6V.We can use the sensors with MAX9812 for applications that require measuring the intensity or frequency of the sound.

Transducer Bone conduction 8 Ohm Speaker 1 Watt Wired Bone Conductor Transducer - 8 Ohm 1 Watt This amazing speaker does not have a movable cone like most From the speakers you've seen, instead, a small metal rod is wrapped with the voice coil. When the current is driven through the coil, the magnetic field makes a piece of metal expands and contracts, if pressed against a flat surface or cavity makes it a speaker! Often these size transducers are pressed against the jaw or ear bone to turn the skull into a speaker socket. The effect is a perfect quality sound that comes from your head and no one else can hear it. You can also press it against your elbow bone and stick a finger in your ear to listen to the audio transmitted through your arm! Code M0113 ✗ Out-of-Stock Price €12.36
