Bridge, string instrument and string vibration detecting method

Abstract

The invention discloses a bridge, a string instrument and a string vibration detecting method. The bridge comprises a body, wherein a plurality of insertion holes are arranged in the body, piezoelectric sensors are detachably connected in the insertion holes, a string fixing part is arranged at one end of each piezoelectric sensor, an insertion pin is arranged at the other end of each piezoelectric sensor, the insertion pins are connected with a control circuit board, a controller is arranged on the control circuit board, and the controller is electrically connected with the piezoelectric sensors. The string instrument is provided with the bridge. The piezoelectric sensors are arranged on the bridge, the piezoelectric sensors are used for detecting the vibration of strings, and the vibration frequency of the strings is utilized for judging and recognizing the pitch and the chord. Compared with the traditional sound collection manner adopting a microphone, the method provided by the invention has the advantages that the accuracy is higher, and the anti-jamming capability is stronger. And the pitch and the chord can be recognized when multiple persons play the instruments together.

Description

technical field [0001] The invention relates to the technical field of sound pickup by stringed musical instruments, in particular to a bridge, a stringed musical instrument and a string vibration detection method. Background technique [0002] Stringed instruments refer to musical instruments that produce sound with stretched strings, including guitars, ukuleles, etc. The guitar includes a guitar body and strings, the guitar body includes a headstock, a neck, a sound box and a saddle; the strings connect the headstock and the saddle. The pronunciation of the guitar is to pluck the strings with your fingers, and the strings start to vibrate. When the guitar strings vibrate, the vibration will be transmitted to the bridge, and the bridge will transmit the vibration to the panel. The resonance between the panel and the body compresses the vibration in the cabinet. The air vibrates to generate sound waves, and the sound is transmitted from the sound hole through the reflection...
