The invention belongs to the technical field of audio recognition, and particularly relates to a string music tremolo automatic detection method which comprises the following steps: S1, preprocessing and framing an input audio, and extracting time sequence features; s2, obtaining an emotion intensity score through an emotion intensity evaluation function; s3, mapping the emotion intensity score into an expected tremor speed, and obtaining a stable tremor speed through exponential smoothing and amplitude limiting; s4, generating a dynamic threshold value changing along with time; and S5, the main tremolo detector calculates the criterion in parallel, compares the criterion with a dynamic threshold value on a synchronization time axis to determine frame-level tremolo, connects adjacent frames to obtain a tremolo segment, and drives threshold value self-adaption by emotional intensity, so that the detection criterion is synchronized with a playing situation, wrong division and over-division are reduced, and the boundary consistency and the stability and accuracy of tremolo estimation are improved.

A floating-tremolo unit comprises a string saddle-assembly means 13 with a tremolo-arm 11 and Z shaped bracket. The Z shaped bracket extends outwardly backwards and beneath the surface height of an electric guitar, engaging with ball bearings (2, 5, figure 3). The ball bearings are in contact with cushioning means in the form of disc shaped compression springs such as Belleville washers. Ideally the bracket is suspended between two axially mounted columnar sets of the compression springs (3, 4, 6, 7, figure 3). The upper set may have clearance for threaded fasteners to adjust the preloading tension. The string saddle-assembly means may be rotated clockwise or anticlockwise, about a pivoting means to generate augmented or diminished pitch-shifting of notes. The entire unit is front-mounted, thereby not requiring machining operations to the rear face of the guitar body during manufacture. Conventional steel or brass ‘sustain’ block may be incorporated optionally. A multitude of spring tensions may be realised by varying combinations.

The invention discloses a sound device with a tremolo eliminating effect and a self-adaptive tremolo eliminating method, and relates to the technical field of sound devices, the sound device with the tremolo eliminating effect comprises a box body with a containing space, a loudspeaker element and a signal processing element, the containing space is internally provided with an element placement table, and the element placement table is internally provided with a signal processing element; the element placement table is fixedly connected with the inner wall of the box body, the loudspeaker element and the signal processing element are arranged on the element placement table, and the containing space is of a spherical structure so as to reduce tremolo caused by sound wave reflection and mechanical vibration.

An electric guitar bridge ball trill system provided by the present invention comprises a bridge bottom plate, the surface of the bridge bottom plate is provided with a placing groove, the side wall of the placing groove in the length direction is provided with a bridge main shaft, and the two ends of the bridge main shaft penetrate through the inner wall of the placing groove to the two sides of the exterior of the bridge bottom plate and are provided with main bearings. The bridge main shaft is rotationally connected with the main bearing; the bridge assembly is arranged in the placing groove, and the bridge assembly is formed by linearly arranging a plurality of bridges; the bridge supporting assemblies are arranged on the two sides of the bridge bottom plate, and the bridge supporting assemblies are rotationally connected with the main bearing. The bridge main shaft is arranged on the side wall of the bridge bottom plate placement groove, the two ends of the bridge bottom plate placement groove are connected with the main bearings, the bridge assemblies are linearly arranged in the placement groove, and the bridge supporting assemblies rotationally connected with the main bearings are arranged on the two sides of the bridge bottom plate, so that the tremolo effect of the electric guitar can be achieved, meanwhile, abrasion between structures is reduced, and the tremolo intonation stability is guaranteed.

A system for stabilizing a tremolo (vibrato) of a guitar includes a tremolo stabilizer and a lockable claw that can be used in place of a traditional tremolo spring and claw, respectively. The stabilizer uses an extension spring as well as a compression spring with an adjustable preload to stabilize the tremolo. The overall length of the stabilizer can be calibrated with a thumbwheel. The locking claw uses anchor screws and a claw screw for restricting movement when the stabilizer is under tension or compression, respectively.

A bridge for a stringed musical instrument is provided. The bridge is machined solid from various metals, selected for their metallurgic and sonorous qualities. It is machined as a movable one-piece solid body and plate, selectively used in combination with a separate machined tremolo block and tremolo arm, or a fixed two-piece system: a body and mounting plate. Increased mass of a rounded, machined design and the qualities of the bridge metals combine to improve sustain of the instrument. The bridge's preferred rounded ergonomic design allows the player hand protection from the string saddles and screws, the bridge itself visually compliments typical guitar contours and provides a surface for branding. It may replace existing bridges or be used in new instruments.

In some aspects, a tremolo for a stringed-instrument includes a tremolo frame and tremolo cams including a laterally spaced-apart curved string contact surfaces at positions and spacings corresponding to string positions of strings for a stringed instrument. The tremolo lever is rotatably mounted to the tremolo frame to rotate about an axis of rotation, an upper portion of the tremolo lever adjacent the tremolo frame and a lower portion extending downwardly from the upper portion, the lower portion including, at or near a distal portion thereof, one or more string retention structures configured to secure string end portions. The upper portion of the tremolo lever includes a first mechanical connector to receive a mating second mechanical connector at a first end portion of an outer lever arm so that forces applied to the outer lever arm by a user to rotate the tremolo lever about the axis of rotation in a first direction of rotation displace the distal portion of the tremolo lever in a first direction to increase a tension in, and a pitch of, strings secured at the distal portion of the tremolo lever and forces applied to the outer lever arm to rotate the tremolo lever about the axis of rotation in a second direction of rotation displace the distal portion of the tremolo lever in a second direction to decrease a tension in, and a pitch of, strings secured at the distal portion of the tremolo lever.
