Rockin’ Patent – Dartmouth College’s “Modulated Electromagnetic Musical System And Associated Methods”

US Patent No. 10,777,181 - Dartmouth College - Modulated Electromagnetic Musical System And Associated Methods - Patents Rock - Russell IP
  • Rockin’ Patent®: US Patent No. 10,777,181
  • Filed: 10 July 2017
  • In the name of: Dartmouth College
  • Title: Modulated Electromagnetic Musical System And Associated Methods
  • What’s claimed: “A modulated electromagnetic (EM) musical system, comprising: an acoustic carrier signal source for generating an acoustic carrier signal; an EM actuator configured to generate an acoustic modulator signal; a linkage element, driven by the EM actuator, that exhibits nonlinear behavior when physically mixing the acoustic carrier signal and the acoustic modulator signal; and an acoustic output coupled with the linkage element to generate acoustic modulation with the non-linear behavior.”
  • Why this patent rocks: This appears to be the patent for the technology underlying Cicada by the company Physical Synthesis, an acoustic synthesiser that converts voltage to vibrations in a mechanical oscillator. The instrument was developed at Dartmouth College by Spencer Topel, a music professor at the time and the founder of Physical Synthesis. Vibrations generated by the voice-coil motors in the actuator are transmitted and amplified by the bridge, causing intermittent and periodic interaction with the soundboard resulting in modulation.

It is a fair concern: patent disputes can be expensive. One option that some businesses may not be aware of is intellectual property (IP) insurance. Important note: Our expertise is

What Does A New UK Government Study Reveal About AI Patents? Published: September 2026 | Last updated: September 2026 A recent government-backed study in the UK has found that AI-related patent applications rose from 5.2% of all US patent applications filed in 2014 to 20.3% in 2023. In other words, AI patent applications now make up roughly one in five filings in the US. The finding comes from a study called AI Skills for Life and
