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.

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.

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.
