[0023] A further embodiment of the carcass 1 in the present invention: the carcass 1 is composed of a cotton pulp layer 14, a wood pulp layer 15, a glass fiber layer 16 and a carbon fiber layer 17. The carcass 1 is made of a composite material composed of multiple layers of materials, and the sound is clearer, richer and louder than the carcass 1 made of the first material.

[0024] A further embodiment of the carcass 1 in the utility model: the cotton pulp layer 14, the wood pulp layer 15, the glass fiber layer 16 and the carbon fiber layer 17 are formed into the carcass 1 by cold pressing. In the prior art, the multi-layer material is pressed into the carcass of the composite material. The cold pressing of the composite board refers to the cold pressing of the composite material pretreated by heating, which is applied to the material manufacturing process in the fields of construction, automobiles, machinery, etc. It uses the hot pressing effect under high pressure to compound the materials together to form a strong and durable composite board. The cold pressing technology is more convenient and more efficient than the traditional hot pressing technology.

[0025] A further embodiment of the annular sound amplifier 11 in the present invention: the annular sound amplifier 11 is in a runway shape, and the cross-section of the annular sound amplifier 11 is U-shaped. The carcass is made into a runway shape so that when the carcass vibrates to generate sound, the air will be further compressed and expanded in the U-shaped cross-section of the sound amplifier 11, thereby generating a louder, thicker and longer sound than a flat carcass, further improving the sound quality.

[0026] A further embodiment of the annular sound amplifier 11 in the utility model: a first arc-shaped transition groove 18 is provided at the connection between the annular sound amplifier 11 and the flat sound amplifier 12. The first transition groove 18 is to prevent the sound amplifier 11 and the flat sound amplifier 12 from breaking when the carcass is cold pressed.

[0027] A further embodiment of the annular sound amplifier 11 in the present invention: a second arc-shaped transition groove 19 is provided at the connection between the annular sound amplifier 11 and the first assembly platform 13 .

[0028] A further embodiment of the hanging edge 2 of the present invention is as follows: a second assembly platform 22 is provided at the inner ring of the assembly groove 21 of the hanging edge 2 , and the first assembly platform 13 is fixed on the second assembly platform 22 .

[0030] A further embodiment of the hanging edge 2 in the present invention is as follows: the hanging edge 2 is in a runway shape, and the cross section of the hanging edge 2 is in a U shape. The U-shaped cross section of the hanging edge 2 will give the entire drum paper a larger moving space when vibrating, so that the amplitude of the drum paper vibration is larger.

[0031] A further embodiment of the hanging edge 2 in the present invention is as follows: a folded portion 25 is provided at the two arc-shaped ends of the hanging edge 2. The folded portion 25 provides more deformation space for the hanging edge 2 when it is deformed due to vibration, thereby preventing the hanging edge 2 from being broken by excessive pulling due to vibration.

[0032] When in use: the carcass 1 is composed of multiple layers of materials to form a composite material carcass, and the sound will be clearer, thicker and louder than the carcass 1 of the first material. In the prior art, multiple layers of materials are pressed into a composite material carcass. Composite board cold pressing refers to the material manufacturing process of cold pressing the pre-treated composite material by heating, which is used in the fields of construction, automobiles, machinery and other fields. It utilizes the effect of hot pressing under high pressure to compound materials together to form a strong and durable composite board. Cold pressing technology is more convenient and efficient than traditional hot pressing technology. The carcass is made into a runway shape so that when the carcass vibrates to produce sound, the air will be further compressed and expanded in the U-shaped cross-section of the sound amplifier 11, thereby producing a louder, thicker and longer sound than a flat carcass, further improving the sound quality. The first transition groove 18 is to prevent the sound amplifier 11 and the flat sound amplifier 12 from breaking when the carcass is cold pressed. The U-shaped cross-section of the suspension edge 2 will give the entire drum paper a larger moving space when it vibrates, making the drum paper vibrate with a larger amplitude. The pleated portion 25 will provide more deformation space for the suspension edge 2 when it is deformed due to vibration, thereby preventing the suspension edge 2 from being excessively pulled and broken due to vibration.
