Technical Field

[0001] The invention relates to an acoustic device, in particular to a loudspeaker. Background Art

[0002] The speaker makes sound by pushing the sound diaphragm to vibrate under the action of the magnetic field, thereby driving the air to vibrate. The existing sound diaphragm is composed of a paper cone and a folding ring. After the paper cone, the voice coil and the elastic wave are assembled, an annular shock-absorbing component needs to be attached to the outside of the drum ring of the folding ring, so as to better install the sound diaphragm between the speaker body and the basin frame. However, the above-mentioned method is to attach the annular shock-absorbing component on the folding ring, which is prone to poor positioning. In order to solve the above-mentioned problems, the existing technology allows the sound diaphragm to have its own shock-absorbing ring, wherein the shock-absorbing ring is located on the outside of the drum ring relatively far away from the paper cone and has a certain height, which results in poor stability of the up and down vibration of the voice coil and the overall height of the speaker cannot be reduced.

[0037] For more details, please refer to Figure 1A , Figure 1C as well as Figure 1D In this embodiment, the paper cone 110a and the vibration-damping ring 120a are embodied as an integrally formed structure, that is, seamlessly connected, wherein the first side edge 121a of the vibration-damping ring 120a is vertically connected to the paper cone 110a. In other words, the paper cone 110a of this embodiment adopts a non-overhanging edge design, which can not only increase the vibration area, but also serve as a single body of the coaxial speaker. Furthermore, the paper cone 110a of this embodiment has an opening 115, and the voice coil 150 is arranged corresponding to the opening 115 and abuts against the periphery of the opening 115, wherein the opening 115a exposes the surface 151 of the voice coil 150. In addition, the speaker 100a of this embodiment may further include a dust cover 160, which is disposed at the opening 115 of the paper cone 110a to cover the surface 151 of the voice coil 150 exposed by the opening 115.

[0038] Next, please refer to Figure 1C and Figure 1DThe damper 130 of this embodiment includes a hollow frame 132 and a plurality of annular structures 134. The hollow frame 132 has an inner edge 131 and an outer edge 133. The annular structures 134 are separately disposed on the hollow frame 132 and are located between the inner edge 131 and the outer edge 133.

[0040] Since the damping ring 120a is integrally connected to the paper cone 110a, the first side edge 121a of the damping ring 120a is connected to the paper cone 110a, and the second side edge 123a of the damping ring 120a and the magnetic component 140 respectively abut the outer edge 131 and the inner edge 133 of the damping wave 130, and the voice coil 150 is disposed in the space S defined by the paper cone 110a, the damping ring 120a, the damping wave 130 and the magnetic component 140 and abuts the paper cone 110a. In this way, the voice coil 150 and the paper cone 110a are suspended by the damping ring 120a, which can effectively reduce the overall height of the speaker 100a, and improve the stability of the linear (up and down) vibration of the voice coil 150 and prevent the voice coil 150 from shaking and deflecting. In addition, compared with the speaker in the prior art having a basin frame, the speaker 100a of this embodiment does not have a basin frame, thereby reducing components and reducing processing costs.
