Problems solved by technology
The traditional guitar produces sound with the vibration of the cabinet, and the volume and range are limited by the resonance box, which cannot be adjusted. However, the electric guitar uses the principle of electromagnetism, and a coil is installed on the body as an electromagnetic pickup device. When the guitar strings When vibrating, the magnetic induction line of the pickup device is cut, so that currents of different frequencies are generated in the wires in the piano body. When these currents are restored by the electronic speaker, the sound of the electric guitar is formed. However, the frequency response of the magnetic pickup is not flat and nonlinear. , In addition, electric guitars cannot overcome the shortcomings of traditional electrical equipment, such as being active, not resistant to electromagnetic interference, and not resistant to corrosion and moisture.

The invention relates to the technical field of guitar structures, in particular to a fiber optic guitar. The fiber optic guitar includes a guitar body, a fiber optic sensor, a Faraday rotating mirror, a transmission cable and a sound pickup processing host, the sound pickup processing host includes a light source module, an optical interference module, a photoelectric conversion and amplificationmodule, a data processing module and a loudspeaker which are connected successively, the fiber optic sensor aims at strings of the guitar body, one end of the fiber optic sensor is connected with theFaraday rotating mirror, and the other end of the fiber optic sensor is connected with the optical interference module through the transmission cable. The fiber optic guitar is novel in structure, the fiber optic sensor is used as a sound wave sensor, after a sound wave signal is restored and processed by the sound pickup processing host, the sound wave signal can be played by a loudspeaking device, and the disadvantages that in the prior art the sound volume, sound value and sound range of a traditional guitar have are limited and non-ajustable and electric guitar magnetic pickup frequency response capacity is not flat nonlinear, device-active, no resistance to electromagnetic interference and no resistant to corrosion and moisture are overcome.
Description
technical field [0001] The invention relates to the technical field of guitar structures, in particular to an optical fiber guitar. Background technique [0002] Existing guitar mainly contains two kinds of traditional guitars and electric guitars. The traditional guitar produces sound with the vibration of the cabinet, and the volume and range are limited by the resonance box, which cannot be adjusted. However, the electric guitar uses the principle of electromagnetism, and a coil is installed on the body as an electromagnetic pickup device. When the guitar strings When vibrating, the magnetic induction line of the pickup device is cut, so that currents of different frequencies are generated in the wires in the piano body. When these currents are restored by the electronic speaker, the sound of the electric guitar is formed. However, the frequency response of the magnetic pickup is not flat and nonlinear. , In addition, electric guitars cannot overcome the shortcomings of ...
