It should be noted that, as Figure 3 shown, it can be obviously seen from the cross-sectional view that the loudspeaker of the embodiment has a butterfly-shaped structure, and the structure stability is good.
[0048] The vibration mechanism comprises a paper basin 21, a rubber ball 22, and a support table 23 between the paper basin 21 and the rubber ball 22, the paper basin 21 is detachably connected with the support 1, the top end face and the bottom end face of the support table 23 are respectively bonded with the paper basin 21 and the rubber ball 22, in the embodiment, the technical means of additionally arranging the support table 23 between the rubber ball 22 and the paper basin 21 can effectively reduce the height of the paper basin 21 without changing the original sound quality of the loudspeaker; the side of the magnetic circuit mechanism away from the support 1 is sequentially penetrated through the rubber ball 22, the support table 23 and the paper basin 21, and the magnetic circuit mechanism is arranged in the support 1, so that the height of the loudspeaker as a whole can be significantly reduced compared with the prior art in which the magnetic circuit mechanism is arranged outside the support 1, and the height of the loudspeaker is reduced by 30% compared with the loudspeaker of the same specification in which the magnetic circuit mechanism is arranged outside the support 1, thereby solving the technical problem of the loudspeaker with excessively high height in the prior art. The rubber ball 22 is also known as a centering fin, and is formed with a plurality of wave-shaped protrusions and has a ring-shaped structure as a whole.
[0049] As shown in Figure 1 and Figure 3 , in the embodiment, the side of the paper basin 21 away from the support 1 comprises a first inclined surface 211, a first flat surface 212 and a second inclined surface 213 connected in sequence, an inner recess with an opening away from the support 1 is formed between the first inclined surface 211, the first flat surface 212 and the second inclined surface 213, a contact surface is formed on the support table 23 and abuts against the first flat surface 212, the top of the support table 23 has a chamfer 231 adapted to the inner wall of the second inclined surface 213, and the chamfer 231 extends along the inner wall of the second inclined surface 213 in the circumferential direction, in the embodiment, the chamfer 231 is additionally arranged on the support table 23, which can facilitate the positioning and assembly of the paper basin 21 on the support table 23, and can also increase the contact area between the paper basin 21 and the support table 23, thereby further improving the stability of the bonding between the paper basin 21 and the support table 23.
[0050] As shown in Figure 1 , Figure 2 and Figure 3 , in the embodiment, a plurality of reinforcing ribs 4 are arranged between the first inclined surface 211 and the second inclined surface 213, the reinforcing ribs 4 are correspondingly arranged in the inner recess, which can effectively strengthen the overall structural strength of the paper basin 21 and avoid the collapse of the paper basin 21 affecting the sound quality of the loudspeaker. In the embodiment, two reinforcing ribs 4 are symmetrically arranged on the paper basin 21, and the number of the reinforcing ribs 4 can be adjusted according to actual needs.
[0051] As shown in Figure 1 and Figure 3As shown, in this embodiment, a clearance opening 215 is provided in the middle of the paper cone 21. The magnetic circuit mechanism includes a U-shaped iron 31, a magnet assembly 32, and a voice coil 33. The magnet assembly 32 is attracted into the cavity of the U-shaped iron 31. The voice coil 33 is sleeved on the outer periphery of the magnet assembly 32, and the top of the voice coil 33 can extend out from the clearance opening 215 to ensure good overall sound quality of the speaker.

The magnets 321 will be transformed into electromagnets 321 and move under the influence of the current. The vibration is transmitted to the paper cone 21 through the voice coil 33, thereby driving the paper cone 21 to vibrate and realize the sound production of the speaker. In this embodiment, the pole piece 322 is a sheet-like low-carbon steel. The inner wall of the U-shaped iron 31 protrudes on the side facing away from the bottom of the bracket 1 and forms a raised platform to increase the placement height of the magnet assembly 32 and prevent the magnet 321 and pole piece 322 on the magnet assembly 32 from being too thick, which would affect the sound quality of the speaker.
[0052] like Figure 1 As shown, in this embodiment, the vibration mechanism also includes a dust cover 5. The end of the second inclined surface 213 is formed with a second flat surface 214. The dust cover 5 is adhered to the second flat surface 214 and used to cover the clearance opening 215 to prevent external dust from falling into the magnetic circuit mechanism through the clearance opening 215, which would cause excessive dust accumulation in the magnetic circuit mechanism and affect the sound quality of the speaker.
[0053] like Figure 4 As shown, in this embodiment, the speaker also includes a fastener 6. A locking hole 311 is provided at the bottom of the U-shaped iron 31, and a mounting hole 11 is also provided at the bottom of the bracket 1 corresponding to the locking hole 311. By arranging the fastener 6 and making the fastener 6 pass through the locking hole 311 and the mounting hole 11 in sequence, the U-shaped iron 31 and the bracket 1 are threadedly connected, thereby fixing the U-shaped iron 31 and preventing the magnet assembly 32 inside the U-shaped iron 31 from vibrating and causing the U-shaped iron 31 to move in series after the voice coil 33 passes through the audio current.
[0054] like Figure 1 and Figure 4As shown, in the embodiment, a plurality of heat dissipation openings 8 are arranged on the side wall surface of the support 1 in a circumferential direction. The support 1 is formed with a first step surface, and the elastic wave 22 is bonded to the first step surface. The support 1 is also formed with a second step surface, and the paper basin 21 is connected to the second step surface. The side wall surface between the first step surface and the second step surface of the support 1 and the side wall surface between the bottom of the support 1 and the first step surface are both provided with a plurality of heat dissipation openings 8 arranged in a circumferential direction. The heat dissipation openings 8 improve the heat dissipation effect of the loudspeaker as a whole, and on the other hand, the support 1 is divided into two independent spaces by the cooperation of the elastic wave 22 and the support table 23, and the heat dissipation openings 8 arranged at different positions of the support 1 can further ensure the air flow balance in the two spaces. The four corners of the second step surface are all provided with connecting holes 9 for connecting external components, and the number of the connecting holes 9 can be adjusted according to actual needs.
