Magnetic energy guide angle sound effect type loudspeaker

Abstract

A magnetic energy guide angle sound effect type loudspeaker comprises a washer, a voice coil, T iron, a permanent magnet, a support and a vibrating diaphragm, and an annular guide angle upper convex ring is arranged on the upper edge of an inner hole of the washer; an upper groove is formed in the upper edge of an inner hole of the washer, the edge of the upper groove protrudes to form an annular lead angle upper protruding ring, the upper groove in the upper edge of the inner hole of the washer is one or a combination of any two of an arc shape, a trapezoid shape, a triangle shape, a right angle shape and a step shape, an annular lead angle pad is fixed to the upper end of the inner hole of the washer, and the edge of the annular lead angle pad protrudes to form an annular lead angle upper protruding ring. The loudspeaker has the advantages that after the structure of the washer is changed, the magnetic energy is provided for the voice coil through the annular lead angle upper convex ring after reducing means such as contraction and expansion, the loudspeaker is high in sound pressure, good in sound effect and natural in tone, and the sound effect can be adjusted according to the size or width of the annular lead angle upper convex ring; the original loudspeaker can also be modified by adopting the structure of the annular lead angle pad.

Description

Technical field [0001] Technical Field The present invention relates to a speaker, and more particularly, to a magnetic steering angle audio speaker. Background technique [0002] Currently use speaker which washer is substantially flat configuration, the magnetic field of the permanent magnet, through the washer magnetic, magnetic field lines are smooth delivery configuration, the audio sound thus emitted pressure is small, the sound effect is poor, low efficiency of the loudspeaker; now the market under the fixed horn material, the way to change a single, more difficult while changing various properties of sound. Inventive content [0003] Object of the present invention is to provide an electromagnetic acoustic transfer more efficient, at the same current and voltage, sound pressure, sound, voice, while the details may lead angle adjustment of the magnetic sound speaker. [0004] The technical solution disclosed in the present invention is: [0005] One kind of magnetic audio...

AI Technical Summary

Problems solved by technology

[0002] The speakers currently used are basically flat plate structures. When the magnetic field of the permanent magnet passes through the washer, the magnetic lines of force are smoothly transmitted. Therefore, the sound pressure is small, the sound effect is poor, and the efficiency of the speaker is low; The current speaker on the market has a single change method when the material is fixed, and it is more difficult to change various characteristics of the sound at the same time
