BACKGROUND OF THE INVENTION
1. Field of the Invention
The present disclosure relates to a percussion instrument, more particularly to a drum. The present disclosure provides an electronic drum pad which can be combined on the drum frame of the jazz drum, whereby the jazz drum can be changed to an electronic drum.
2. Description of the Related Art
A jazz drum, also known as drum kit, is set of combination of the hand hit instruments and the foot hit instruments having with different types and different tones, and can be applied to a variety of music types. An electronic drum is a percussion instrument using an electronic synthesizer to produce drumbeats, and includes two parts of the electronic synthesizers and a striking region portion. The electronic drum looks like the jazz drum in appearance, but has relatively smaller size and smaller drumhead.
Based on the diversification in types of music and performance, many drummers must be familiar with both of jazz drum and electronic drum. However, it is very space-consuming while both of the jazz drum and the electronic drum are placed in the performance occasions or practice environments at the same time. In addition, the positions and heights of the large jazz drum, medium jazz drum, snare jazz drum and cymbal are different from the electronic drum, so the drummer who is familiar to the jazz drum already also must spend time for re-adapting to the positions and heights of the electronic drums for re-training feel. Therefore, if the jazz drums can be converted into the electronic drums directly, the problem of re-adaption for drummers can be solved and the space is prevented from being occupied by two sets of drums.
SUMMARY OF THE INVENTION
The problem to be solved in this disclosure is how to convert a jazz drum to an electronic drum. An aspect of the embodiment of the present disclosure is to provide an electronic drum pad which can be combined on a jazz drum to convert the jazz drum to an electronic drum. The electronic drum pad comprises: a base body having a frame rim protruding upwardly at an edge part of an upper surface thereof and a frame dike protruding downwardly at an edge part of a lower surface thereof; a striking region portion arranged in a center of the base body; a first trigger configured for sensing the vibration of the striking region portion, arranged inside a first electronic component groove of the base body, and located in a bottom part of the striking region portion; a second trigger configured for sensing the vibration of the frame rim, arranged inside a second electronic component groove of the base body, and the second electronic component groove being close to the frame rim.
The base body can be combined the drum frame of a jazz drum by the frame dike, the lower surface of the base body and a drum skin of the jazz drum are spaced from a distance. When a drum stick knocks the striking region portion or the frame rim, the first trigger senses the vibration of the striking region portion, and the second trigger senses the vibration of the frame rim. The first trigger and the second trigger output a vibration signal to a trigger module. The trigger module then transforms the vibration signal into a simulated drum head sound or simulated drum frame sound, and the simulated sounds are outputted via a sound box or earphones.
The materials of the base body and the striking region portion are selected from rubber or silica gel.
The base body has at least one decorative groove at the upper surface thereof outside against the striking region portion. An LED lighting unit set and a circuit unit related to the LED lighting unit set are embedded in the decorative groove, and the circuit unit is coupled with the first trigger.
