Abstract

Provided is a loudspeaker, comprising a cone support, a magnetic circuit system installed on the cone support, a voice coil installed in the magnetic field of the magnetic circuit system, a cone connected to the voice coil, an elastic wave for fixedly connecting the voice coil and the cone, and an extension tube disposed on the back of the cone; one end of the extension tube is connected to the cone, and the other end is connected to the cone support. The loudspeaker has extension tubes disposed on the edge of the cone, thus having good elasticity, and allowing the cone to maintain good linear working characteristics in a large dynamic operation; in addition, the extension tubes are disposed on the back of the cone, without occupying the vibration area of the cone, thus greatly improving the low-frequency characteristics of the loudspeaker, and ensuring that the loudspeaker has working performance of high efficiency and high fidelity.
