Optical string device

Abstract

The invention relates to an optical string device. The optical string device mainly comprises an optical string and an optical path system. The optical string comprises a first functional sensing optical fiber with a strain information sensing function, a second functional sensing optical fiber with a position information sensing function, a reinforcing unit and a protective layer; the optical path system comprises a light source module, a first coupler, an optical pickup and a loudspeaker; the optical pickup comprises a sound frequency information processing part and a sound intensity information processing part. Optical strings are utilized to realize simultaneous sensing of the position and the action intensity of the external force action point, the optical pickup is further utilized to convert the position information of the external force action point into sound frequency information, the intensity information of the external force action is converted into sound intensity information, the sound intensity information is matched and output through the loudspeaker, a brand-new thought is provided for design and preparation of a stringed musical instrument, the expression form ofthe stringed musical instrument is greatly enriched, and more possibilities are provided for development of the field of musical instruments.

Description

technical field [0001] The invention belongs to the technical field of musical instruments, and in particular relates to an optical string device. Background technique [0002] Strings are one of the important components of stringed instruments. The regular vibration of strings makes stringed instruments produce changes in sound intensity and sound frequency, which is the basic principle of stringed instrument performance. Existing strings often require both hands to play, such as one hand plucks the strings to control the sound intensity, and the other hand changes the effective string length by changing the position of the strings, thereby producing a change in the sound frequency, and then achieving the purpose of playing , that is, the existing strings often need two hands to cooperate to operate, wherein one hand is used to control the sound intensity, and the other hand is used to control the sound frequency. However, this way of playing with both hands is not conduc...
