    摘要： A detection system is provided for detecting a musical note played on a string instrument having a fretboard provided with a plurality of conductive frets and conductive strings. The system includes at least one conductor coupled to each of the frets; an inverter having a first terminal coupled to the conductor and a second terminal coupled to the conductive string, the inverter being configured to logically invert a signal transmitted therethrough, such that when the conductive string is pressed against one of the frets allowing thereby for a signal to be transmitted therethrough, the signal is sequentially inverted between two logical states at a frequency being dependent on the distance between the inverter and the fret; a frequency detector configured to measure the frequency; and a controller configured for determining the location of the fret along the fretboard in accordance with the frequency, and to thereby detect the musical note.

    摘要： A control system controls the motion of a physical subject such as a mechanical system to damp or enhance the motion via a single transducer which alternates in a time-discrete manner between the task of reading a signal indicative of the state of the subject and the task of influencing said state by the application of a force. Control of motion or vibration is achieved through a series of actuating pulses interleaved with sensing operations. The same single transducer alternately acts as input to the control system from the subject and output from the control system to the subject. The control system provides full and individual control of all important harmonic modes of vibration of a subject mechanical system.

    摘要： An apparatus and method for amplifying low amplitude vibrations from stringed instruments, and in particular guitars while reducing Gaussian and 60 Hz hum noise from the signal. In particular, the invention incorporates the use of one or more bipolar magnets in conjunction with high precision differential amplifiers and a power source. The bipolar magnets may be arranged at varying locations on the guitar as long as they are within range to induce an electrical signal in the strings when they are played. The signal is then fed through the amplifier circuitry whereby noise is eliminated and then played through a standard speaker.

    摘要： A guitar-like electronic musical instrument for use with a synthesizer has six pitch strings on the neck which the player depresses onto conductive frets to determine the selected semitone. A transducer senses if the player forces the string laterally on the fret and if the string is so laterally forced (bent) beyond a threshold, further pitch detection is inhibited. The fret construction can be much simplified and there is no danger of spurious notes being caused by contact with adjacent strings.

    摘要： A guitar-like electronic musical instrument for use with a synthesizer (18) has a body (20) and a neck (22). The neck carries six pitch strings (40) which the player depresses onto conductive frets to determine the selected note. The body carries six trigger strings (50) which can be plucked or strummed to initiate or trigger the desired notes. Alternatively they can be triggered by six keys (70). The trigger strings (50) and pitch strings (40) are at an angle to each other. The three lower strings and the three higher strings can be triggered together by group trigger keys (300,302) and all six strings triggered by a master trigger key (204). If either of switches (200,202) are actuated, notes will be triggered automatically as soon as the pitch string is depressed onto the fret. Touching of the string is detected by an a.c. waveform superposed on a d.c. potential. Hall effect devices are used to sense triggering by the trigger strings (50) or keys (70). Each fret has eleven conductive sections so that sideways bending can be detected, and bend detection coils are embedded in the finger board for the same purpose. A vibrato arm (210) using a Hall effect device can be used to introduce a vibrato effect. A console (32) enables resetting of the note of each string, storing various set values for each string, transposition of the instrument as a whole and a `Capo` effect to be obtained. A pedal unit (30) allows some functions to be selectively operated during playing, such as variation in the decay rate, or sustaining of notes played while a hold pedal is depressed.
