Abstract
A stringed instrument includes a body, a string, a string exciting device and a bridge. The body supports the string, the string exciting device and the bridge. The string has a scale length determined by a distance between a first support point and a second support point. The string exciting device is designed to be driven by an electrical signal having a certain frequency and vibrate the string by applying an excitation signal having a frequency corresponding to the frequency of the electrical signal. The bridge has the first support point and a surface located between the first support point and the second support point and designed to come into contact with the string during vibration of the string.
Claims19
A stringed instrument comprising:
- a bridge having a first support point and a surface;
- a plurality of strings, each of the strings supported by the first support point and a second support point, the surface located between the first support point and the second support point, the surface being designed to come into contact with the strings during vibration of the strings;
- a string exciting device driven by an electrical signal to directly vibrate the strings;
- and
- a body supporting the bridge, the strings and the string exciting device,
- wherein the electrical signal driving the string exciting device is generated from sound information outside the stringed instrument and supplied into the stringed instrument to vibrate the strings.
A stringed instrument comprising:
- a bridge having a first support point and a surface;
- a plurality of strings, each of the strings supported by the first support point and a second support point, the surface located between the first support point and the second support point, the surface being designed to come into contact with the strings during vibration of the strings;
- a positive feedback oscillator circuit;
- and
- a body supporting the bridge, the strings and a string exciting device, wherein the positive feedback oscillator circuit comprising:
- the string exciting device driven by an electrical signal to vibrate the strings;
- an exciter provided for each of the strings to vibrate each of the strings;
- a converter provided for each of the strings to produce an electric signal;
- and
- an amplifier;
- wherein even when each of the strings is not vibrated, an electric signal produced in the positive feedback oscillator circuit serves as a trigger signal to cause a positive feedback to start vibrating each of the strings.
