In some embodiments of the present application, the method for determining the spatial position of each sound emitting region of a metallic musical instrument by the detecting component 320 includes:
for the top voice zone, the detecting component 320 performs cross scanning, processes the obtained data, finds the characteristic points of the top voice zone, and finds the midpoints of the two groups of characteristic points, namely the midpoints in the X, Y directions respectively, and can refer to fig. 4 and 5;
For the side tone regions, first, the angle information of the center point of each tone region with respect to the metal musical instrument is obtained, the detection component 320 performs circular scanning so that the scanning track passes through each surrounding tone region, then processes the scanning data, specifically, referring to fig. 6 and fig. 7, it can be seen that eight minimum values of the green line in the data map correspond to the angle positions of the center points of eight surrounding tone regions, then determines the position of the center point of each surrounding tone region along the radius direction of the metal musical instrument, scans and reads and processes the data along the radius direction, specifically, referring to fig. 8 and fig. 9, X1 and X2 in the data map are two feature points, the distance between the center points of the tone regions in the radial direction can be known by solving the midpoints of the two feature points, and the angle and the radial position (corresponding to θ and ρ of the polar coordinate system respectively) of the center point of the surrounding tone region are determined, namely, the spatial position of the tone region is determined.
The same applies to other surrounding regions of sound.
It can be understood that each sound zone is a standard ellipse, and only the center point of the ellipse needs to be found, and each sound zone has corresponding size information, so that the spatial position of each sound zone can be known. In some embodiments, the manner in which the obtained data is processed includes, but is not limited to, filtering, derivative taking, etc., mathematical means, and is not described herein. In some embodiments, the XY axis is controlled to realize a cross scan, a circular scan, a radial scan, and the like.
In some embodiments of the present application, a method of determining a distance at which a test part 310 is struck includes setting an initial relative position of a detecting assembly 320 and the test part 310 in a X, Y, Z direction, scanning using the detecting assembly 320 to obtain a relative positional relationship of the detecting assembly 320 and a sound region of a metallic instrument, calculating in conjunction with the initial relative position to obtain a relative position of the test part 310 and the sound region, sending the test part 310 to a suitable position at which the metallic instrument can be struck, and extending the test part 310 a suitable distance for testing. It will be appreciated that the relative positions of the outer sensor, the dc plunger and the electromagnet in the XYZ direction are initially fixed and the relative values can be measured. The infrared distance measuring sensor is used for scanning in the front, the XYZ relative position relation between the infrared distance measuring sensor and the sounding region of the metal musical instrument is obtained, and the relative position between the electromagnet and the sounding region is obtained through simple calculation. Thus, the electromagnet is sent to a proper position where it can be knocked to the metal musical instrument, and the dc motor pushrod 311 is extended a distance that has been tested in advance.
In some embodiments of the present application, the tuning method of the tuning members 220 includes setting a target frequency, moving each tuning member 220 to both upper and lower sides of the same position of the sound zone, decreasing the frequency of the sound zone by pressing down, tuning in such a manner that the frequency of the sound zone increases by pressing down, knocking the sound zone by the test member 310 after each pressing operation, receiving the sound frequency and comparing with the target frequency, and judging the direction of the next pressing until the frequency meets the target frequency.
It will be appreciated that the present application controls the position and amount of depression by an algorithm. In general, pressing down from top to bottom causes the frequency of the soundtrack to decrease and pressing up from bottom to top causes the frequency to increase. First, a target frequency is set. If the force from top to bottom is too large, the frequency is smaller than the target frequency, then the lower push rod is used for pressing from bottom to top at the same position of the sound zone, the frequency can be increased, the force of the jacking during tuning can be controlled through the mode, and the condition of excessive adjustment caused by the too large force is avoided.
