Abstract
The invention discloses a kind of loud speaker of anti-distortion, comprise T iron, magnet, washer, voice coil loudspeaker voice coil, support and sound basin; Magnet is enclosed within T iron; Washer is enclosed within T iron, and washer is positioned at the top of magnet, has gap between washer and T iron; Voice coil loudspeaker voice coil is enclosed within T iron, and the lower end of voice coil loudspeaker voice coil extend in gap; Support is fixed on washer; Sound basin is located at the leading section of support; The magnetic circuit intensifier of aluminum is fixed with in the upper end of T iron; The sidewall that described magnetic circuit intensifier comprises base plate and extends to sound basin direction from base plate.Structure of the present invention, well can prevent audio distortions, and can improve radiating effect.
Description
Technical field
The present invention relates to loud speaker.
Background technology
As shown in Figure 1, existing loud speaker comprises T iron 1, magnet 2, washer 3, voice coil loudspeaker voice coil 4, support 5 and sound basin 6; Magnet 2 is enclosed within T iron 1; Washer 3 is enclosed within T iron 1, and washer 3 is positioned at the top of magnet 2, has gap between washer 3 and T iron 1; Voice coil loudspeaker voice coil 4 is enclosed within T iron 1, and the lower end of voice coil loudspeaker voice coil 4 extend in gap; Support 5 is fixed on washer 3; Sound basin 6 is located at the leading section of support 5.After voice coil loudspeaker voice coil 4 is energized, the excitatory sound basin that makes of voice coil loudspeaker voice coil 4 pairs of magnet 2 produces vibration.In excitatory process, as shown in Figure 1, can form toroid 7, in said structure, magnet and washer are all conducive to forming magnetic circuit, but at T iron place, the formation of toroid can be restricted, and therefore, whole magnetic circuit is bad, the easy distortion of sound.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of loud speaker of anti-distortion.
The technical scheme solved the problems of the technologies described above is: a kind of loud speaker of anti-distortion, comprises T iron, magnet, washer, voice coil loudspeaker voice coil, support and sound basin; Magnet is enclosed within T iron; Washer is enclosed within T iron, and washer is positioned at the top of magnet, has gap between washer and T iron; Voice coil loudspeaker voice coil is enclosed within T iron, and the lower end of voice coil loudspeaker voice coil extend in gap; Support is fixed on washer; Sound basin is located at the leading section of support; The magnetic circuit intensifier of aluminum is fixed with in the upper end of T iron; The sidewall that described magnetic circuit intensifier comprises base plate and extends to sound basin direction from base plate.
Said structure, owing to being provided with the magnetic circuit intensifier be made up of base plate and sidewall, when after voice coil loudspeaker voice coil energising, voice coil loudspeaker voice coil produces vibration to the excitatory sound basin that makes of magnet.In excitatory process, magnetic field is first introduced in base plate after sidewall, finally gets back to magnet, makes magnetic circuit closed loop better, well can prevent audio distortions; In addition, in excitatory process, can produce a large amount of heats, by arranging the magnetic circuit intensifier of aluminum, and magnetic circuit intensifier has base plate and sidewall, and area of dissipation is large, therefore, is conducive to quick heat radiating.
As improvement, described base plate is provided with hole, and base plate is enclosed within the upper end of T iron.This structure is convenient to fixing magnetic circuit intensifier.
As improvement, be provided with dust cap at the middle part of sound basin.Described dust cap can avoid dust to enter into the quality affecting sound in support.
Accompanying drawing explanation
Fig. 1 is the loadspeaker structure figure of prior art.
Fig. 2 is the structural representation of loud speaker of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
As shown in Figure 2, the loud speaker of anti-distortion comprises T iron 1, magnet 2, washer 3, voice coil loudspeaker voice coil 4, support 5 and sound basin 6; Magnet 2 is enclosed within T iron 1; Washer 3 is enclosed within T iron 1, and washer 3 is positioned at the top of magnet 2, has gap between washer 3 and T iron 1; Voice coil loudspeaker voice coil 4 is enclosed within T iron 1, and the lower end of voice coil loudspeaker voice coil 4 extend in gap; Support 5 is fixed on washer 3; Sound basin 6 is located at the leading section of support 5, is provided with dust cap 10 at the middle part of sound basin 6, prevents dust from entering in support and affecting tonequality.The magnetic circuit intensifier of aluminum is fixed with in the upper end of T iron; The sidewall 9 that described magnetic circuit intensifier comprises base plate 8 and extends to sound basin direction from base plate, base plate 8 is provided with hole, and magnetic circuit intensifier is enclosed within T iron upper end and fixes by passing hole.
In the present invention, owing to being provided with the magnetic circuit intensifier be made up of base plate 8 and sidewall 9, as shown in Figure 2, after voice coil loudspeaker voice coil 4 is energized, the excitatory sound basin that makes of voice coil loudspeaker voice coil 4 pairs of magnet 2 produces vibration.In excitatory process, magnetic field is first introduced in base plate 8 after sidewall 9, finally gets back to magnet 2, makes magnetic circuit closed loop 7 better, well can prevent audio distortions; In addition, in excitatory process, can produce a large amount of heats, by arranging the magnetic circuit intensifier of aluminum, and magnetic circuit intensifier has base plate and sidewall, and area of dissipation is large, therefore, is conducive to quick heat radiating.
