Title: MULTI-TUBE RESONATOR OF STRINGED INSTRUMENT, AND STRINGED INSTRUMENT
Abstract:
A stringed instrument and multi-tube resonator (100) thereof. The multi-tube resonator (100) comprises: a main body comprising a first resonant tube (111) and a second resonant tube (112) having both ends closed, abutting each other, and being arranged in parallel; air openings (131, 132, 133) provided on the main body; a mounting rod (150) used to mount the main body within a resonance cavity; and two magnets (170) respectively located on the two ends of the main body and having magnetic poles oppositely arranged. For the multi-tube resonator (100) of the stringed instrument, when a sound generator receives a force and vibrates, the sound generator is provided with a magnetic property as a result of the effect of the magnets (170) arranged at the two ends of the main body, and the vibration amplitude thereof increases as a result of the effect of the magnetic field of the magnets (170) at the two ends. At the same time, variations in the magnetic field enable the multi-tube resonator (100) to increase the speed of propagation of the acoustic energy and enhance the radiated acoustic energy and the energy of harmonics in respective frequency bands, thereby increasing the volume and reverberation of the stringed instrument, and improving sound quality and timbre, i.e., making a stringed instrument more pleasant to the ear.
