The voice coil bobbin 140 is a hollow cylindrical structure, and the magnetic core column 124 Concentrically disposed and sleeved on the magnetic core barrel 24 while being received in the magnetic field gap 125. The outer surface of the voice coil bobbin 14 is fixed to the voice coil 130, and is away from the magnetic circuit. One end of the system 120 is fixedly coupled to a central position of the diaphragm 150. When the voice coil bobbin 14 〇 vibrates with the voice coil 13 ,, the vibrating 貘 15 〇 vibrates 'to move the air around the vibration Acoustic wave is generated.

The shape of the diaphragm 150 is not limited, and is related to its specific application, such as when the diaphragm 150 is applied to a large speaker. The diaphragm 150 can be a hollow cone structure; When the vibrating membrane 150 is applied to a microspeaker, the vibrating membrane 150 may be a disc-like structure. The bottom end of the vibrating membrane 150 and the voice coil bobbin 140 may be connected by bonding, and the other end of the vibrating membrane 150 The edge is connected to the bracket 110, that is, the end of the diaphragm 150 connected to the bracket 110 can move up and down to achieve the effect of vibration and sound. In the embodiment, the f) diaphragm 150 is a hollow cone structure. [0014] The centering piece 160 is a wavy ring structure composed of a plurality of concentric rings. The inner edge of the centering piece 160 is sleeved on the voice coil frame 140 for supporting the sound. a ring skeleton 140 having an outer edge fixed at an end of the bracket 110 adjacent to the center hole 113. The centering piece 160 has a large radial rigidity and a small axial rigidity, thereby The voice coil 130 is freely moved up and down in the magnetic field gap 125 without lateral movement, and the voice coil 130 is prevented from coming into contact with the magnetic circuit system 120, and functions as a center of the fixed diaphragm 150.

The larger the diameter of the voice coil 1.3 〇 wire structure, the greater the current that the voice coil 00 can withstand. When the voice coil I30 receives the audio signal, the voice coil 130 produces a change in the intensity of the audio signal. The varying magnetic field interacts with the magnetic field generated by the magnetic field system 120 in the magnetic field gap 125, thereby forcing the voice coil 130 to move piston movement along its axial direction. The voice coil I30 drives the voice coil bobbin to perform the lacquer movement. Since one end of the voice coil bobbin 140 is connected to the vibrating membrane 150, the vibrating membrane 150 vibrates, and the vibrating membrane pushes the surrounding air to make the speaker 100 emit sound.读 Read see Figure 4, the voice coil!
