Description

cajon stand

This creation is related to the fixing frame of the wooden drum box, especially a fixing frame that can adjust the structure to match a variety of wooden drum boxes of different sizes.

When the orchestra plays music, it often uses instruments of different timbres to combine with each other to show a diverse and beautiful performance. Among them, the wooden box drum (commonly known as: Cajon or Cajon) is a percussion instrument that has become popular in recent years. Due to its degree of freedom High and easy to use, it is relatively suitable for beginners to learn. In addition, it can create a timbre and rhythm similar to jazz drums when struck. At the same time, it is easy to carry because of its small size, making the cajon very popular. Show scene. As the name suggests, the cajon looks like a wooden box and has a striking surface, and there is a circular resonance hole on the other side of the striking surface, so that the sound can be expanded and transmitted through the resonance hole.

When the player plays the cajon, the player usually steps on a pedal to drive the hammer connected to the pedal to beat the cajon. As shown in Figure 8, the cajon percussion device disclosed in the Chinese Patent No. M570516 9. It discloses the technical means of using the pedal mechanism 91 to drive the hammer mechanism 92 to beat the cajon 93. Since the action of beating the cajon 41 is relatively simple, the player chooses to assign the task of playing the cajon 93 to the feet. Rather than directly slapping the striking surface of the cajon 93 with the palm, thereby allowing the hands to be assigned to play more complicated musical instruments, the player can use the pedal mechanism 91 which is set apart from the hammer mechanism 92 without changing the hammer 921. Under the position, the position of pedal 911 is determined according to the body shape or leg length of the individual.

Because during the playing of the cajon 93, the landing point of the hammer 921 on the cajon 93 significantly affects the tone color emitted, therefore, in order to avoid the playing quality not as expected, the relative distance between the cajon 93 and the corresponding hammer 921 The position is extremely important. As shown in Figure 8, the player connects the cajon 93 and the hammer 921 with a cajon frame 94. The cajon frame 94 is provided with screw holes and corresponding adjustment bolts 95. The player waits to After the cajon 93 is installed, the adjusting bolt 95 is screwed in the screw hole, and one end of the adjusting bolt 95 is pushed against the outer peripheral surface of the cajon 93 to fix the position of the cajon 93. The cajon 93 and the hammer 921 are connected and fixed through the cajon frame 94 , so that the relative position of the two can be stabilized for the player, and the performance quality of the cajon 93 can be stabilized.

However, performers often need to travel between different exhibition venues. The wooden cajon stand is assembled before the performance starts and dismantled after the performance. Because the components of the conventional wooden cajon stand are relatively bulky, repeated assembly and handling processes It is troublesome and labor-intensive. Secondly, the cajon has many styles of different sizes. The width difference between cajons of different sizes can even reach more than 10 cm. The process of adjusting the bolt is extremely tedious and inefficient.

On the other hand, as mentioned earlier, the cajon is provided with a circular hole-shaped resonance hole, so that the sound can be enlarged and transmitted through the resonance hole, and in a relatively spacious performance venue (such as; a concert hall, an opera house, etc.) ), the player often needs to amplify the sound of the cajon to enough decibels through the microphone, so the player usually clamps the microphone on the inner edge of the resonance hole with a support frame, so that the microphone is directly facing the resonance hole for sound collection . However, clamping the microphone to the inner edge of the cajon's resonance hole through the support frame will affect the performance quality of the cajon. The support frame of the microphone will block the resonance structure of the drum sound, which will lead to a drop in tone. The assembly process of the conventional wooden cajon stand is time-consuming and labor-intensive, and the microphone support frame has a negative impact on the tone, so there is still room for improvement.
