Problems solved by technology

This greatly reduces the effective vibration area and reduces the output of low frequency energy
Especially for speakers with small diameter and hope to produce better low-frequency energy, the loss of low-frequency energy is greater
In addition, when the loudspeaker operates in large dynamics, due to the obvious dynamic restraint effect of the R side, the nonlinear distortion of the piston movement of the cone is caused.

Abstract

The invention provides a loudspeaker. The loudspeaker comprises a basin rack, a magnetic circuit system, a voice coil, a voice basin, a wave damper and a telescopic tube, wherein the magnetic circuit system is mounted on the basin rack, the voice coil is mounted in a magnetic field of the magnetic circuit system, the voice basin is connected with the voice coil, the wave damper is used for fixedly connecting the voice coil and the voice basin, and the telescopic tube is arranged on the back face of the voice basin; one end of the telescopic tube is connected with the voice basin, and the other end of the telescopic tube is connected with the basin rack. According to the loudspeaker provided by the invention, the telescopic tube is arranged at the edge of the voice basin and has good telescoping performance, so that the voice basin can keep good linear operating characteristics during large dynamic operation; the telescopic tube is arranged on the back face of the voice basin, so that the vibration area of the voice basin is not occupied, the low-frequency characteristics of the loudspeaker are improved greatly, and the loudspeaker can have the working performance of high efficiency and high fidelity.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to a loudspeaker. Background technique [0002] The horn is a transducer device that converts electrical signals into acoustic signals. When different electronic energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the cone to vibrate. Because the electronic energy changes at any time, the coil of the horn will move forward or backward, so the sound of the horn The pot will follow the movement, and these movements will change the density of the air to produce sound. [0003] In the existing speakers, in order to allow the sound cone to move forward and backward, and to isolate the air on the front and back of the sound cone without causing an acoustic short circuit, foam edges, rubber edges, or paper are added to the edges of the sound cone. R edge of the design such as ruffle edge....
