Problems solved by technology

[0002] There are always snares inside the clapper box. Generally, the snares are simply attached to the inner wall of the front panel of the box, and have no adjustment function, which makes the sound effect of the clapper box relatively simple; there are also some clapper boxes that are only on one side. A regulator is added, and since several snares are connected side by side on the inner ...

Abstract

The invention discloses a cajon which comprises a box body, a plurality of snares and two adjustment devices. Each adjustment device includes an installation plate, a connection plate, a rotating shaft which is fixedly connected to the lower end of the connection plate and can be rotatably installed on the installation plate, a swing arm vertically and fixedly connected to the rotating shaft, and a slide block fixedly connected to the swing arm. Each installation plate is arranged on an inner side wall of a side plate near one side of a front face plate, and an arc hole for guiding one of the slide blocks to move is formed in the installation plate. The upper end of each connection plate is fixedly connected to the corresponding snare. The slide block pass through the arc holes and extend out of the box body. Through adjustment of positions of the slide blocks on two sides of the box body, distances between the snares and inner side walls of the front face plate of the box body can be adjusted. The fitting degrees of the snares and the cajon are more consistent, and more cajon sound effects can be created by means of different adjusted status of the two adjustment devices. Besides, feet arranged on the bottom of the cajon can be adapted to fields with poor environments, so that the cajon is more widely applicable.

Example Embodiment

[0010] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:
[0011] see figure 1 and figure 2 The clapper box of the present invention includes a box body 1, a plurality of snares 2 arranged on the inner side wall of the front panel of the box body 1, and is used to adjust the distance between the snare strings 2 and the inner side wall of the front panel of the box body 1 and is separately placed on the inner side wall of the front panel of the box body 1. Two adjustment devices on the two side plates of the box body 1, the upper end of each snare 2 is fixedly connected to the upper part of the inner side wall of the front panel of the box body 1, and the lower end is respectively connected with the corresponding adjustment device.
[0012] Each of the adjustment devices includes a mounting plate 3, a connecting plate 4, a rotating shaft 5 fixed horizontally on the lower end of the connecting plate 4 and rotatably mounted on the mounting plate 3, and a swing arm 6 with one end vertically fixed to one end of the rotating shaft 5 As well as the slider 7 fixedly connected to the other end of the swing arm 6, since the structures of the two adjustment devices are consistent, an adjustment device is taken as an example to illustrate: the installation plate 3 is arranged on the inner side wall of the side plate and adjacent to the front On the panel side, the mounting plate 3 is also formed with an arc-shaped hole 8 for the movement guidance of the slider 7, the upper end of the connecting plate 4 is fixedly connected with the corresponding snare 2, and the slider 7 passes through the arc-shaped hole 8 Stretch out to the outside of box body 1.
[0013] By adjusting the position of the sliders 7 on both sides of the box 1 in the arc-shaped hole 8, the swing arm 6 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the connecting plate 4 to rotate, so that the snare 2 corresponding to the connecting plate 4 is in front of the box 1. The distance between the inner side walls of the panels will then vary. like figure 1 and figure 2 As shown, when the slider 7 is at the uppermost position of the arc-shaped hole 8, the distance between the snare 2 and the inner wall of the front panel of the box body 1 is the smallest, and the degree of bonding between the snare 2 and the clapper box is the largest; on the contrary, the slider 7 When it is at the lowermost position of the arc-shaped hole 8, the distance between the snare string 2 and the inner side wall of the front panel of the box body 1 is the largest, and the bonding degree between the snare string 2 and the clapper box is the smallest.
[0014] Each of the connecting plates 4 is respectively connected with two snares 2 .
[0015] The four top corners of the bottom of the box body 1 are respectively provided with a foot 9, each of which includes a foot rod and a tapered leather sheath, and each of the bottom of the foot rod is respectively provided with a spherical The upper part of each said conical leather cover is respectively formed with a spherical groove capable of accommodating the spherical block. Through the cooperation of the spherical block and the spherical groove, the angle of the conical holster can be adjusted relative to the foot rod. The feet can adapt to venues with poor environment, which makes the applicability of the racket box wider.
[0016] In summary, the content of the present invention is not limited to the above-mentioned embodiments, and those skilled in the art can propose other embodiments within the technical guidance of the present invention, but these embodiments are all included in the scope of the present invention. within range.
