H04R1/288 - CPC Classification

Classification description:

Details of transducers, loudspeakers or microphones; Arrangements for obtaining desired frequency or directional characteristics for obtaining desired frequency characteristic only; Transducer mountings or enclosures modified by provision of mechanical or acoustic impedances, e.g. resonator, damping means; Reduction of undesired resonances, i.e. standing waves within enclosure, or of undesired vibrations, i.e. of the enclosure itself by means of damping material, e.g. as cladding for loudspeaker transducers
