Electronic Mute for Trumpet & Cornet
thingiverse
This is a versatile system for the trumpet and cornet. It can be used as follows: 1. As an active mute (all holes at the bottom sealed from the inside except for the pipe output). 2. Electronic mute, install a condenser microphone on top, embed a small amplifier circuit within and integrate a voltage boost circuit to convert 1.5V dc to the required voltage for amplification. My chosen voltage converter is http://www.ebay.com/itm/DC-DC-Boost-Converter-Step-Up-Module-1-5V-to-5V-500mA-for-phone-MP4-MP3-Arduino-/351390823155?pt=LH_DefaultDomain_0&hash=item51d08672f3. I've ordered the microphone amplification module http://www.ebay.com/itm/1pcs-Microphone-MIC-amplifier-module-Voice-Module-NEW-/201226168458?pt=LH_DefaultDomain_0&hash=item2eda03a88a, which I plan to test for mic sensitivity and audio fidelity. Following my tests on these modules with a small speaker, they seem effective. However, this should be enough to produce quality sound via headphones.
