ABSTRACT:
A drum comprises a drum body made of at least one fiber layer. The drum body is provided with a drumhead at each of two opposite ends thereof. The drumheads are positioned on two reinforced frames disposed at both ends of the drum body by two drum hoops, so that the contact area between the drumheads and the drum body can be reduced through the reinforced frames. In addition, the reinforced frames reinforce the structure and maintain the shape of the drum body. Plural positioning screws are inserted through the periphery of the respective drum hoops, and the drum body is provided with plural fixing members to be screwed with the positioning screws. By such arrangements, the drum not only has the advantages of reinforced structure, light weight and easy production but exert a better resonance effect, making the sound produced by the drum more robust and powerful.
