About the speaker aluminum basin frame

    The basin frame is the "skeleton" of a conical speaker, which can combine diaphragm, folding ring, centering plate, magnet, magnetic element, etc. It can also play the role of installing the speaker on the box. When the speaker is working, the diaphragm will conduct the vibration to the folding ring, then to the frame, and further to the box. This transmission will also propagate in the opposite direction, interfering with other waves, and the vibration situation is very complex.

    Aluminum has low rigidity and strength, but aluminum can compensate for this deficiency by increasing the amount of material per unit volume. Thick cast aluminum frames have strong rigidity. At present, in order to ensure strength, the aluminum materials used on high-end basin frames adopt the method of using thicker cast aluminum and increasing the cross-sectional area, so most aluminum basin frames look very rough.
 The appearance of aluminum does not change much after long-term use. It is not easy to detect changes in appearance,
1. Aluminum has higher internal damping than iron and is less prone to resonance.
2. Aluminum is easy to dissipate heat, especially for temperature sensitive neodymium iron boron magnets, and the basin frame can become an important factor for temperature stability.
The above are all the advantages of aluminum, but this material also has two disadvantages. Aluminum has poor metal fatigue and lacks elasticity,
