Embodiment Construction

[0024] The following will describe in detail the implementation of the detection platform for the absence of bow-toothed saws according to the present invention.

[0025] The bow hair is an important component of the bow, with a total length of 76 cm. The bow rod is the support for the bow hair. The length of the bow is 2.4 feet. It is made of river reed bamboo. At the end of the bow, the ponytail is placed between the two strings to rub the strings for sound.

[0026] Most of the bow hair is ponytail, and it is also imitated by nylon silk. To measure whether the bow hair can be durable and wear-resistant, it mainly depends on whether the bow hair is arranged neatly and flat, with the same length and uniform thickness. Good bow hair requires no broken ends, no softness, no messy twists, etc. When choosing a bow stick, you should pay attention to the length that meets the standard, and also take into account the solid texture, aging, coordinated thickness, well-proportioned, ...

Abstract

The invention relates to a detection platform for the lack of a bow tooth saw, including: a side plate, which is formed by heating and bending six pieces of maple wood to form the frame of the violin, and the side plate includes an upper side plate, a middle side plate and a lower side plate ;Sound column, a cylindrical wooden column supported between the panel and the back panel inside the resonance box, located on one side of the treble foot of the piano bridge, used to transmit the vibration of the panel to the back panel while supporting the panel; trim , consisting of two ebony strips sandwiched by a pine strip, used to reinforce the body; the sound beam is a wooden strip glued to the panel inside the resonance box, located on the side of the bass foot of the bridge, and used to transmit the vibration of the strings; The signal triggering device is connected with the shape comparison device, and is used to send out a tooth saw missing signal when the received similarity is less than or equal to the preset percentage threshold, otherwise, send out a maintenance signal. Through the present invention, valuable reference data can be provided for the replacement of bow hairs.

Description

technical field [0001] The invention relates to the field of bow hair detection, in particular to a detection platform for missing bow hair tooth saws. Background technique [0002] The horsehair tail is tightly tied to both ends of the bow, and the player can change its tension when drawing the bow, so that single string or multiple strings can be played more smoothly at the same time. Hold the bow tightly and press your fingers on the bow hairs to change the tension of the bow. The length and style of the bows are different, the shortest is only 20 centimeters long. In the 16th century, the violin was an extremely popular instrument in dance music, so its short bow was about 35 cm long. The bows used in music concerts are longer, and some are even twice as long as the instrument itself. Some bows have a knob at the end for easy manipulation of the bow tension. [0003] The bow hair is composed of 150-200 white horse tail hairs, and these horse tail hairs are connected ...
