Full-frequency loudspeaker provided with double voice coils

Abstract

The invention discloses a full-frequency loudspeaker provided with double voice coils, which comprises a loudspeaker bracket, a loudspeaker diaphragm, a dustproof cap, a spring wave, the voice coils, a magnetic circuit structure and a base bracket, wherein the loudspeaker diaphragm, the dustproof cap and the spring wave are installed on the loudspeaker bracket; the voice coils are used for driving the diaphragm to vibrate; the loudspeaker bracket and the magnetic circuit structure are installed on the base bracket; the two voice coils comprise a voice coil I and a voice coil II which are wound along the reverse direction; the magnetic circuit structure is a radial magnetic circuit structure which comprises a magnetic conductor and a permanent magnet; the magnetic conductor takes on a ring shape and is provided with a ring-shaped groove in the middle; and the permanent magnet takes on a ring shape and is arranged in the ring-shaped groove of the magnetic conductor in a suspension way.

Description

A full-range speaker with dual voice coils Technical field The invention relates to a loudspeaker. Background technique In the design of full-band speakers, due to the generally adopted transverse magnetic circuit, whether it is a single voice coil or a dual voice coil, the sound quality of the speaker will be affected due to magnetic permeability issues. Summary of the invention The problem to be solved by the present invention is to provide a dual-voice-coil full-range speaker that can greatly improve the efficiency and sound quality of the speaker. The technical solution adopted by the present invention is: a dual-voice-coil full-range speaker includes a speaker stand, a speaker diaphragm, a dust cap, a spring wave, a voice coil, a magnetic circuit structure, and a base stand. The speaker diaphragm and dust cap , The elastic wave is installed on the speaker bracket, the voice coil drives the diaphragm to vibrate, the speaker bracket and the magnetic circuit structure are ...
