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 bow hair tooth saw loss detecting platform which comprises the components of a side plate which is formed through heating, bending and forming six maple blocks, thereby forming a frame of a violin, wherein the side plate comprises an upper side plate, a middle side plate and a lower side plate; a sound post which is a cylindrical wood post that is supported between a panel and a back plate in a resonance chamber and is located at one side of a violin bridge high-pitch leg and is used for supporting the panel and transmitting vibration of the panel to a backboard; a decorating rim which is composed of two ebony strips and one pine strip and is used for reinforcing a violin body; a sound beam which is a wood strip that is adhered to the panel in the resonance chamber is arranged at one side of the violin bridge bass leg and is used for transmitting vibration of a string; and signal triggering equipment which is connected with profile contrasting equipment and is used for transmitting a tooth saw loss signal when the received similarity is lower than or equal with a preset percentage threshold, and otherwise, transmitting a use maintaining signal. Through the bow hair tooth saw loss detecting platform, valuable reference data can be supplied for changing of the bow hair.

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 ...
