G10H2220/461 - CPC Classification

Classification description:

Input/output interfacing specifically adapted for electrophonic musical tools or instruments Transducers, i.e. details, positioning or use of assemblies to detect and convert mechanical vibrations or mechanical strains into an electrical signal, e.g. audio, trigger or control signal

Sub-classes:

G10H2220/465 » Bridge-positioned, i.e. assembled to or attached with the bridge of a stringed musical instrument 11
G10H2220/505 » Dual coil electrodynamic string transducer, e.g. for humbucking, to cancel out parasitic magnetic fields 41
G10H2220/521 » Hall effect transducers or similar magnetic field sensing semiconductor devices, e.g. for string vibration sensing or key movement sensing 31
G10H2220/525 » Piezoelectric transducers for vibration sensing or vibration excitation in the audio range; Piezoelectric strain sensing, e.g. as key velocity sensor; Piezoelectric actuators, e.g. key actuation in response to a control voltage 136
G10H2220/561 » Piezoresistive transducers, i.e. exhibiting vibration, pressure, force or movement -dependent resistance, e.g. strain gauges, carbon-doped elastomers or polymers for piezoresistive drumpads, carbon microphones 37
G10H2220/565 » Shielding, electromagnetic or magnetic, e.g. for transducers, i.e. for controlling, orienting or suppressing magnetic fields or for preventing unintentional generation, propagation and reception of electromagnetic energy in electrophonic musical instruments, their vicinity or their interconnections 19
