Patent ID: 10587958

Abstract:
A moving-coil loudspeak includes a vibrating diaphragm, a suspension, a voice coil, a magnetic circuit, and a support. The suspension includes a surround and a first spider. One side of the surround is connected to an outer surface of the vibrating diaphragm. The first spider vertically stands below a connection between the surround and the vibrating diaphragm, and one side of the first spider is connected to an inner surface of the vibrating diaphragm. The voice coil is located below the center of the vibrating diaphragm. The magnetic circuit is located below the voice coil, where a coil on the voice coil is disposed at a central position of a magnetic gap. After the voice coil is powered on, a generated magnetic induction force drives the voice coil to vibrate and produce a sound by using the vibrating diaphragm. The support supports the magnetic circuit.
