In this article, George Ntanavaras describes the design and operation of a system consisting of the ACH-01 accelerometer and a preamplifier with an integrated analog signal processor. With this system, it will be possible to measure the acceleration, the velocity, and a loudspeaker cone’s excursion at the low frequencies. Also, a loudspeaker cabinet’s panel vibrations will be easily obtained. Originally published on audioXpress June 2011.
Meanwhile, the author has made un upgrade of this design and has available PCBs and Front panels to build the Accelerometer amplifier. You can find more information here :
