Vibration isolation pick-up unit for stringed instruments

Abstract

The invention provides a vibration isolation type sound pickup unit of a string instrument. The unit mainly comprises a face board, an acoustic wave pickup head, a vibration isolation body and a fixing body. According to the vibration isolation type sound pickup unit, the acoustic wave pickup head is arranged under an inner face plate of a resonance chamber. The acoustic wave pickup head and the fixing body are connected by the vibration isolation body. The vibration isolation body is a vibration reducer between the acoustic wave pickup head and the fixing body. The vibration isolation body is made of vibration isolation material, and is of a suspension structure or a cantilever structure or a damping pad block structure. The unit can be used with an ordinary speaker. The audio signals of string instruments are connected to an ordinary speaker. The sound volume can be adjusted. The reverberation, treble and bass sections can all be adjusted. The sound tone can also be beautified. If it is necessary to improve the bass sound of the acoustic board, the face board can be covered with a rubber layer, the method can enable an electroacoustic erhu of the size of an ordinary erhu to play the octave note. The quantity of the acoustic wave pickup heads in the resonance chamber is equal to or more than one. Different types of pickup heads can be used for acquiring different tones, thus exerting the potential of the speaker in full capacity.

Description

technical field [0001] The present invention relates to string music, especially the "vibration-isolation pickup unit for string music". sound unit. Background technique [0002] The most common pick-up methods in electro-acoustic strings are: 1. The pressure-variable pick-up method uses piezoelectric sensing elements to pick up the sound by using the pressure change when the string vibrates to deform it, such as for guitars. Piezoelectric pick-up rods, its low-frequency sound quality is poor, and the instrument needs to be equipped with a preamplifier, or a dedicated guitar speaker. 2. The string cutting magnetic field line pickup method uses a special magnetic induction coil to pick up sound by cutting its magnetic force line when the string vibrates. This kind of pickup is generally a special pickup for musical instruments, and its signal is weak. The material requires a high iron content, and some guitars use multiple magnetic induction coils to pick up sound, and conn...

In addition, the panel of the stringed music is the vibrating board or the sounding board. The sounding board is mostly wooden, and the erhu is made of python skin. case

Electro-acoustic instruments usually only have one set of audio cables input to the speaker, which cannot fully play the role of the speaker
